Goiardi

Goiardi is an implementation of the Chef server (http://www.opscode.com) written in Go. It can either run entirely in memory with the option to save and load the in-memory data and search indexes to and from disk, drawing inspiration from chef-zero, or it can use MySQL or PostgreSQL as its storage backend.

Like all software, it is a work in progress. Goiardi now, though, should have all the functionality of the open source Chef Server, plus some extras like reporting and event logging. It does not support other Enterprise Chef type features like organizations or pushy at this time. When used, knife works, and chef-client runs complete successfully. Almost all chef-pendant tests successfully successfully run, with a few disagreements about error messages that don't impact the clients. It does pretty well against the official chef-pedant, but because goiardi handles some authentication matters a little differently than the official chef-server, there is also a fork of chef-pedant located at https://github.com/ctdk/chef-pedant that's more custom tailored to goiardi.

Many go tests are present as well in different goiardi subdirectories.

DEPENDENCIES

Goiardi currently has nine dependencies: go-flags, go-cache, go-trie, toml, the mysql driver from go-sql-driver, the postgres driver, logger, go-uuid, and serf.

To install them, run:

   go get github.com/jessevdk/go-flags
   go get github.com/pmylund/go-cache
   go get github.com/ctdk/go-trie/gtrie
   go get github.com/BurntSushi/toml
   go get github.com/go-sql-driver/mysql
   go get github.com/lib/pq
   go get github.com/ctdk/goas/v2/logger
   go get github.com/codeskyblue/go-uuid
   go get github.com/hashicorp/serf/client

from your $GOROOT, or just use the -t flag when you go get goiardi.

If you would like to modify the search grammar, you'll need the peg package. To install that, run

   go get github.com/pointlander/peg

In the search/ directory, run peg -switch -inline search-parse.peg to generate the new grammar. If you don't plan on editing the search grammar, though, you won't need that.

INSTALLATION

Install go. (http://golang.org/doc/install.html) You may need to upgrade to go 1.2 to compile all the dependencies. Go 1.3 is also confirmed to work.
Make sure your $GOROOT and PATH are set up correctly per the Go installation instructions.
Download goairdi and its dependencies.

go get -t github.com/ctdk/goiardi
Run tests, if desired. Several goiardi subdirectories have go tests, and chef-pedant can and should be used for testing goiardi as well.
Install the goiardi binaries.

go install github.com/ctdk/goiardi
Run goiardi.

goiardi

Or, you can look at the goiardi releases page on github at https://github.com/ctdk/goiardi/releases and see if there are precompiled binaries available for your platform.

You can get a list of command-line options with the '-h' flag.

Goiardi can also take a config file, run like goiardi -c /path/to/conf-file. See etc/goiardi.conf-sample for an example documented configuration file. Options in the configuration file share the same name as the long command line arguments (so, for example, --ipaddress=127.0.0.1 on the command line would be ipaddress = "127.0.0.1" in the config file.

Currently available command line and config file options:

   -v, --version          Print version info.
   -V, --verbose          Show verbose debug information. Repeat for more
			  verbosity.
   -c, --config=          Specify a config file to use.
   -I, --ipaddress=       Listen on a specific IP address.
   -H, --hostname=        Hostname to use for this server. Defaults to hostname
                          reported by the kernel.
   -P, --port=            Port to listen on. If port is set to 443, SSL will be
                          activated. (default: 4545)
   -i, --index-file=      File to save search index data to.
   -D, --data-file=       File to save data store data to.
   -F, --freeze-interval= Interval in seconds to freeze in-memory data
                          structures to disk (requires -i/--index-file and
                          -D/--data-file options to be set). (Default 300
                          seconds/5 minutes.)
   -L, --log-file=        Log to file X
   -s, --syslog           Log to syslog rather than a log file. Incompatible
                          with -L/--log-file.
       --time-slew=       Time difference allowed between the server's clock and
                          the time in the X-OPS-TIMESTAMP header. Formatted like
                          5m, 150s, etc. Defaults to 15m.
       --conf-root=       Root directory for configs and certificates. Default:
                          the directory the config file is in, or the current
                          directory if no config file is set.
   -A, --use-auth         Use authentication. Default: false.
       --use-ssl          Use SSL for connections. If --port is set to 433, this
                          will automatically be turned on. If it is set to 80,
                          it will automatically be turned off. Default: off.
                          Requires --ssl-cert and --ssl-key.
       --ssl-cert=        SSL certificate file. If a relative path, will be set
                          relative to --conf-root.
       --ssl-key=         SSL key file. If a relative path, will be set relative
                          to --conf-root.
       --https-urls       Use 'https://' in URLs to server resources if goiardi
                          is not using SSL for its connections. Useful when
                          goiardi is sitting behind a reverse proxy that uses
                          SSL, but is communicating with the proxy over HTTP.
       --disable-webui    If enabled, disables connections and logins to goiardi
                          over the webui interface.
       --use-mysql        Use a MySQL database for data storage. Configure
                          database options in the config file.
       --use-postgresql   Use a PostgreSQL database for data storage.
                          Configure database options in the config file.
       --local-filestore-dir= Directory to save uploaded files in. Optional when
                          running in in-memory mode, *mandatory* for SQL
                          mode.
       --log-events       Log changes to chef objects.
   -K, --log-event-keep=  Number of events to keep in the event log. If set,
                          the event log will be checked periodically and
                          pruned to this number of entries.
   -x, --export=          Export all server data to the given file, exiting
                          afterwards. Should be used with caution. Cannot be
                          used at the same time as -m/--import.
   -m, --import=          Import data from the given file, exiting
                          afterwards. Cannot be used at the same time as 
                          -x/--export.
   -Q, --obj-max-size=    Maximum object size in bytes for the file store.
                          Default 10485760 bytes (10MB).
   -j, --json-req-max-size= Maximum size for a JSON request from the client.
                          Per chef-pedant, default is 1000000.
       --use-unsafe-mem-store Use the faster, but less safe, old method of
                          storing data in the in-memory data store with
                          pointers, rather than encoding the data with gob
                          and giving a new copy of the object to each
                          requestor. If this is enabled goiardi will run
                          faster in in-memory mode, but one goroutine could
                          change an object while it's being used by
                          another. Has no effect when using an SQL backend.
       --db-pool-size=    Number of idle db connections to maintain. Only
                          useful when using one of the SQL backends.
                          Default is 0 - no idle connections retained
       --max-connections= Maximum number of connections allowed for the
                          database. Only useful when using one of the SQL
                          backends. Default is 0 - unlimited.
       --use-serf         If set, have goidari use serf to send and receive
                          events and queries from a serf cluster. Required
                          for shovey.
       --serf-event-announce Announce log events over serf and joining the serf
                          cluster, as serf events. Requires --use-serf.
       --serf-addr=       IP address and port to use for RPC communication
                          with a serf agent. Defaults to 127.0.0.1:7373.
       --use-shovey       Enable using shovey for sending jobs to nodes.
			  Requires --use-serf.
       --sign-priv-key=   Path to RSA private key used to sign shovey
                          requests.

Options specified on the command line override options in the config file.

If goiardi is not running in use-auth mode, it does not actually care about .pem files at all. You still need to have one to keep knife and chef-client happy. It's like chef-zero in that regard.

If goiardi is running in use-auth mode, then proper keys are needed. When goiardi is started, if the chef-webui and chef-validator clients, and the admin user, are not present, it will create new keys in the --conf-root directory. Use them as you would normally for validating clients, performing tasks with the admin user, or using chef-webui if webui will run in front of goiardi.

In auth mode, goiardi supports versions 1.0, 1.1, and 1.2 of the Chef authentication protocol.

Note: The admin user, when created on startup, does not have a password. This prevents logging in to the webui with the admin user, so a password will have to be set for admin before doing so.

UPGRADING

Upgrading goiardi is generally a straightforward process. Usually all you should need to do is get the new sources and rebuild, or download the appropriate new binary. However, sometimes a little more work is involved. Check the release notes for the new release in question for any extra steps that may need to be done. If you're running one of the SQL backends, you may need to apply database patches (either with sqitch or by hand), and in-memory mode especially may require using the data import/export functionality to dump and load your chef data between upgrades if the binary save file compatibility breaks between releases. However, while it should not happen often, occasionally more serious preparation will be needed before upgrading. It won't happen without a good reason, and the needed steps will be clearly outlined to make the process as painless as possible.

As a special note, if you are upgrading from any release prior to 0.6.1-pre1 to 0.7.0 and are using one of the SQL backends, the upgrade is one of the special cases. Between those releases the way the complex data structures associated with cookbook versions, nodes, etc. changed from using gob encoding to json encoding. It turns out that while gob encoding is indeed faster than json (and was in all the tests I had thrown at it) in the usual case, in this case json is actually significantly faster, at least once there are a few thousand coobkooks in the database. In-memory datastore (including file-backed in-memory datastore) users are advised to dump and reload their data between upgrading from <= 0.6.1-pre1 and 0.7.0, but people using either MySQL or Postgres have to do these things:

Export their goiardi server's data with the -x flag.
Either revert all changes to the db with sqitch, then redeploy, or drop the database manually and recreate it from either the sqitch patches or the full table dump of the release (provided starting with 0.7.0)
Reload the goiardi data with the -m flag.

It's a fairly quick process (a goiardi dump with the -x flag took 15 minutes or so to load with over 6200 cookbooks) at least, but if you don't do it very little of your goiardi environment will work correctly. The above steps will take care of it.

Logging

By default, goiardi logs to standard output. A log file may be specified with the -L/--log-file flag, or goiardi can log to syslog with the -s/--syslog flag on platforms that support syslog. Attempting to use syslog on one of these platforms (currently Windows and plan9 (although plan9 doesn't build for other reasons)) will result in an error.

Log levels

Log levels can be set in goiardi with either the log-level option in the configuration file, or with one to four -V flags on the command line. Log level options are "debug", "info", "warning", "error", and "critical". More -V on the command line means more spewing into the log.

MySQL mode

Goiardi can now use MySQL to store its data, instead of keeping all its data in memory (and optionally freezing its data to disk for persistence).

If you want to use MySQL, you (unsurprisingly) need a MySQL installation that goiardi can access. This document assumes that you are able to install, configure, and run MySQL.

Once the MySQL server is set up to your satisfaction, you'll need to install sqitch to deploy the schema, and any changes to the database schema that may come along later. It can be installed out of CPAN or homebrew; see "Installation" on http://sqitch.org for details.

The sqitch MySQL tutorial at https://metacpan.org/pod/sqitchtutorial-mysql explains how to deploy, verify, and revert changes to the database with sqitch, but the basic steps to deploy the schema are:

Create goiardi's database: mysql -u root --execute 'CREATE DATABASE goiardi'
Optionally, create a separate mysql user for goiardi and give it permissions on that database.
In sql-files/mysql-bundle, deploy the bundle: sqitch deploy db:mysql://root[:<password>]@/goiardi

To update an existing database deployed by sqitch, run the sqitch deploy command above again.

If you really really don't want to install sqitch, apply each SQL patch in sql-files/mysql-bundle by hand in the same order they're listed in the sqitch.plan file.

The above values are for illustration, of course; nothing requires goiardi's database to be named "goiardi". Just make sure the right database is specified in the config file.

Set use-mysql = true in the configuration file, or specify --use-mysql on the command line. It is an error to specify both the -D/--data-file flag and --use-mysql at the same time.

At this time, the mysql connection options have to be defined in the config file. An example configuration is available in etc/goiardi.conf-sample, and is given below:

[mysql]
	username = "foo" # technically optional, although you probably want it
	password = "s3kr1t" # optional, if you have no password set for MySQL
	protocol = "tcp" # optional, but set to "unix" for connecting to MySQL
			 # through a Unix socket.
	address = "localhost"
	port = "3306" # optional, defaults to 3306. Not used with sockets.
	dbname = "goiardi"
	# See https://github.com/go-sql-driver/mysql#parameters for an
	# explanation of available parameters
	[mysql.extra_params]
		tls = "false"

Postgres mode

Goiardi can also use Postgres as a backend for storing its data, instead of using MySQL or the in-memory data store. The overall procedure is pretty similar to setting up goiardi to use MySQL. Specifically for Postgres, you may want to create a database especially for goiardi, but it's not mandatory. If you do, you may also want to create a user for it. If you decide to do that:

Create the user: $ createuser goiardi <additional options>
Create the database, if you decided to: $ createdb goiardi_db <additional options>. If you created a user, make it the owner of the goiardi db with -O goiardi.

After you've done that, or decided to use an existing database and user, deploy the sqitch bundle in sql-files/postgres-bundle. If you're using the default Postgres user on the local machine, sqitch deploy db:pg:<dbname> will be sufficient. Otherwise, the deploy command will be something like sqitch deploy db:pg://user:password@localhost/goairdi_db.

The Postgres sqitch tutorial at https://metacpan.org/pod/sqitchtutorial explains more about how to use sqitch and Postgres.

Set use-postgresql in the configuration file, or specify --use-postgresql on the command line. It's also an error to specify both -D/--data-file flag and --use-postgresql at the same time like it is in MySQL mode. MySQL and Postgres cannot be used at the same time, either.

Like MySQL, the Postgres connection options must be specified in the config file at this time. There is also an example Postgres configuration in the config file, and can be seen below:

# PostgreSQL options. If "use-postgres" is set to true on the command line or in
# the configuration file, connect to postgres with the options in [postgres].
# These options are all strings. See 
# http://godoc.org/github.com/lib/pq#hdr-Connection_String_Parameters for details
# on the connection parameters. All of these parameters are technically optional,
# although chances are pretty good that you'd want to set at least some of them.
[postgresql]
	username = "foo"
	password = "s3kr1t"
	host = "localhost"
	port = "5432"
	dbname = "mydb"
	sslmode = "disable"

General Database Options

There are two general options that can be set for either database: --db-pool-size and --max-connections (and their configuration file equivalents db-pool-size and max-connections). --db-pool-size sets the number of idle connections to keep open to the database, and --max-connections sets the maximum number of connections to open on the database. If they are not set, the default behavior is to keep no idle connections alive and to have unlimited connections to the database.

It should go without saying that these options don't do much if you aren't using one of the SQL backends.

Event Logging

Goiardi has optional event logging. When enabled with the --log-events command line option, or with the "log-events" option in the config file, changes to clients, users, cookbooks, data bags, environments, nodes, and roles will be tracked. The event log can be viewed through the /events API endpoint.

If the -K/--log-event-keep option is set, then once a minute the event log will be automatically purged, leaving that many events in the log. This is particularly recommended when using the event log in in-memory mode.

The easiest way to use the event log is with the knife-goiardi-event-log knife plugin. It's available on rubygems, or at github at https://github.com/ctdk/knife-goiardi-event-log.

The event API endpoints work as follows:

GET /events - optionally taking offset, limit, from, until, object_type, object_name, and doer query parameters.

List the logged events, starting with the most recent. Use the offset and limit query parameters to view smaller chunks of the event log at one time. The from, until, object_type, object_name, and doer query parameters can be used to narrow the results returned further, by time range (for from and until), the type of object and the name of the object (for object_type and object_name) and the name of the performer of the action (for doer). These options may be used in singly or in concert.

DELETE /events?purge=1234 - purge logged events older than the given id from the event log.

GET /events/1234 - get a single logged event with the given id.

DELETE /events/1234 - delete a single logged event from the event log.

A user or client must be an administrator account to use the /events endpoint.

The data returned from the event log should look something like this:

{
  "actor_info": "{\"username\":\"admin\",\"name\":\"admin\",\"email\":\"\",\"admin\":true}\n",
  "actor_type": "user",
  "time": "2014-05-06T07:40:12Z",
  "action": "delete",
  "object_type": "*client.Client",
  "object_name": "pedant_testclient_1399361999-483981000-42305",
  "extended_info": "{\"name\":\"pedant_testclient_1399361999-483981000-42305\",\"node_name\":\"pedant_testclient_1399361999-483981000-42305\",\"json_class\":\"Chef::ApiClient\",\"chef_type\":\"client\",\"validator\":false,\"orgname\":\"default\",\"admin\":true,\"certificate\":\"\"}\n",
  "id": 22
}

Reporting

Goiardi now supports Chef's reporting facilities. Nothing needs to be enabled in goiardi to use this, but changes are required with the client. See http://docs.opscode.com/reporting.html for details on how to enable reporting and how to use it.

There is a goiardi extension to reporting: a "status" query parameter may be passed in a GET request that lists reports to limit the reports returned to ones that match the status, so you can read only reports of chef runs that were successful, failed, or started but haven't completed yet. Valid values for the "status" parameter are "started", "success", and "failure".

To use reporting, you'll either need the Chef knife-reporting plugin, or use the knife-goiardi-reporting plugin that supports querying runs by status. It's available on rubygems, or on github at https://github.com/ctdk/knife-goiardi-reporting.

Import and Export of Data

Goiardi can now import and export its data in a JSON file. This can help both when upgrading, when the on-disk data format changes between releases, and to convert your goiardi installation from in-memory to MySQL (or vice versa). The JSON file has a version number set (currently 1.0), so that in the future if there is some sort of incompatible change to the JSON file format the importer will be able to handle it.

Before importing data, you should back up any existing data and index files (and take a snapshot of the SQL db, if applicable) if there's any reason you might want it around later. After exporting, you may wish to hold on to the old installation data until you're satisfied that the import went well.

Remember that the JSON export file contains the client and user public keys (which for the purposes of goiardi and chef are private) and the user hashed passwords and password salts. The export file should be guarded closely.

The -x/--export and -m/--import flags control importing and exporting data. To export data, stop goiardi, then run it again with the same options as before but adding -x <filename> to the command. This will export all the data to the given filename, and goiardi will exit.

Importing is ever so slightly trickier. You should remove any existing data store and index files, and if using an SQL database use sqitch to revert and deploy all of the SQL files to set up a completely clean schema for goiardi. Then run goiardi with the new options like you normally would, but add -m <filename>. Goiardi will run, import the new data, and exit. Assuming it went well, the data will be all imported. The export dump does not contain the user and client .pem files, so those will need to be saved and moved as needed.

Theoretically a properly crafted export file could be used to do bulk loading of data into goiardi, thus goiardi does not wipe out the existing data on its own but rather leaves that task to the administrator. This functionality is merely theoretical and completely untested. If you try it, you should back your data up first.

Berks Universe Endpoint

Starting with version 0.6.1, goiardi supports the berks-api /universe endpoint. It returns a JSON list of all the cookbooks and their versions that have been uploaded to the server, along with the URL and dependencies of each version. The requester will need to be properly authenticated with the server to use the universe endpoint.

The universe endpoint works with all backends, but with a ridiculous number of cookbooks (like, loading all 6000+ cookbooks in the Chef Supermarket), the Postgres implementation is able to take advantage of some Postgres specific functionality to generate that page significantly faster than the in-mem or MySQL implementations. It's not too bad, but on my laptop at home goiardi could generate /universe against the full 6000+ cookbooks of the supermarket in ~350 milliseconds, while MySQL took about 1 second and in-mem took about 1.2 seconds. Normal functionality is OK, but if you have that many cookbooks and expect to use the universe endpoint often you may wish to consider using Postgres.

Serf

As of version 0.8.0, goiardi has some serf integration. At the moment it's mainly used for shovey (see below), but it will also announce that it's started up and joined a serf cluster.

If the --serf-event-announce flag is set, goiardi will announce logged events from the event log and starting up and joining the serf cluster over serf as serf user events. Be aware that if this is enabled, something will need to read these events from serf. Otherwise, the logged events will pile up and eventually take up all the space in the event queue and prevent any new events from being added.

Shovey

Shovey is a facility for sending jobs to nodes independently of a chef-client run, like Chef Push but serf based.

Shovey requirements

To use shovey, you will need:

Serf installed on the server goiardi is running on.
Serf installed on the node(s) running jobs.
schob, the shovey client, must be installed on the node(s) running jobs.
The knife-shove plugin must be installed on the workstation used to manage shovey jobs.

The client can be found at https://github.com/ctdk/schob, and a cookbook for installing the shovey client on a node is at https://github.com/ctdk/shovey-jobs. The knife-shove plugin can be found at https://github.com/ctdk/knife-shove or on rubygems.

Shovey Installation

Setting goiardi up to use shovey is pretty straightforward.

Once goiardi is installed or updated, install serf and run it with serf agent. Make sure that the serf agent is using the same name for its node name that goiardi is using for its server name.
Generate an RSA public/private keypair. Goiardi will use this to sign its requests to the client, and schob will verify the requests with it.

	$ openssl genrsa -out shovey.pem 2048 # generate 2048 bit private key
	$ openssl rsa -in shovey.pem -pubout -out shovey.key # public key

Obviously, save these keys.

Run goiardi like you usually would, but add these options: --use-serf --use-shovey --sign-priv-key=/path/to/shovey.pem
Install serf and schob on a chef node. Ensure that the serf agent on the node is using the same name as the chef node. The shovey-jobs cookbook makes installing schob easier, but it's not too hard to do by hand by running go get github.com/ctdk/schob and go install github.com/ctdk/schob.
If you didn't use the shovey-jobs cookbook, make sure that the public key you generated earlier is uploaded to the node somewhere.
Shovey uses a whitelist to allow jobs to run on nodes. The shovey whitelist is a simple JSON hash, with job names as the keys and the commands to run as the values. There's a sample whitelist file in the schob repo at test/whitelist.json, and the shovey-jobs cookbook will create a whitelist file from Chef node attributes using the usual precedence rules. The whitelist is drawn from node["schob"]["whitelist"].
If you used the shovey-jobs cookbook schob should be running already. If not, start it with something like schob -VVVV -e http://chef-server.local:4545 -n node-name.local -k /path/to/node.key -w /path/to/schob/test/whitelist.json -p /path/to/public.key --serf-addr=127.0.0.1:7373. Within a minute, goiardi should be aware that the node is up and ready to accept jobs.

At this point you should be able to submit jobs and have them run. The knife-shove documentation goes into detail on what actions you can take with shovey, but to start try knife goiardi job start ls <node name>. To list jobs, run knife goiardi job list. You can also get information on a shovey job, detailed information of a shovey job's run on one node, cancel jobs, query node status, and stream job output from a node with the knife-shove plugin. See the plugin's documentation for more information.

See the serf docs at http://www.serfdom.io/docs/index.html for more information on setting up serf. One serf option you may want to use, once you're satisfied that shovey is working properly, is to use encryption with your serf cluster.

The shovey API is documented in the file shovey_api.md in the goiardi repository.

Shovey In More Detail

Every thirty seconds, schob sends a heartbeat back to goiardi over serf to let goiardi know that the node is up. Once a minute, goiardi pulls up a list of nodes that it hasn't seen in the last 10 minutes and marks them as being down. If a node that is down comes back up and sends a heartbeat back to goiardi, it is marked as being up again. The node statuses are tracked over time as well, so a motivated user could track node availability over time.

When a shovey run is submitted, goiardi determines which nodes are to be included in the run, either via the search function or from being listed on the command line. It then sees how many of the nodes are believed to be up, and compares that number with the job's quorum. If there aren't enough nodes up to satisfy the quorum, the job fails.

If the quorum is satisfied, goiardi sends out a serf query with the job's parameters to the nodes that will run the shovey job, signed with the shovey private key. The nodes verify the job's signature and compare the job's command to the whitelist, and if it checks out begin running the job.

As the job runs, schob will stream the command's output back to goiardi. This output can in turn be streamed to the workstation managing the shovey jobs, or viewed at a later time. Meanwhile, schob also watches for the job to complete, receiving a cancellation command from goiardi, or to timeout because it was running too long. Once the job finishes or is cancelled or killed, schob sends a report back to goiardi detailing the job's run on that node.

Tested Platforms

Goiardi has been built and run with the native 6g compiler on Mac OS X (10.7, 10.8, and 10.9), Debian squeeze and wheezy, a fairly recent Arch Linux, FreeBSD 9.2, and Solaris. Using Go's cross compiling capabilities, goiardi builds for all of Go's supported platforms except Dragonfly BSD and plan9 (because of issues with the postgres client library). Windows support has not been tested extensively, but a cross compiled binary has been tested successfully on Windows.

Goiardi has also been built and run with gccgo (using the -compiler gccgo option with the go command) on Arch Linux. Building it with gccgo without the go command probably works, but it hasn't happened yet. This is a priority, though, so goiardi can be built on platforms the native compiler doesn't support yet.

Note regarding goiardi persistence and freezing data

As mentioned above, goiardi can now freeze its in-memory data store and index to disk if specified. It will save before quitting if the program receives a SIGTERM or SIGINT signal, along with saving every "freeze-interval" seconds automatically.

Saving automatically helps guard against the case where the server receives a signal that it can't handle and forces it to quit. In addition, goiardi will not replace the old save files until the new one is all finished writing. However, it's still not anywhere near a real database with transaction protection, etc., so while it should work fine in the general case, possibilities for data loss and corruption do exist. The appropriate caution is warranted.

DOCUMENTATION

In addition to the aforementioned Chef documentation at http://docs.opscode.com, more documentation specific to goiardi can be viewed with godoc. See http://godoc.org/code.google.com/p/go.tools/cmd/godoc for an explanation of how godoc works. The goiardi godocs can also be viewed online at http://godoc.org/github.com/ctdk/goiardi.

TODO

See the TODO file for an up-to-date list of what needs to be done. There's a lot.

BUGS

There's going to be a lot of these for a while, so we'll just keep those in a BUGS file, won't we?

WHY?

This started as a project to learn Go, and because I thought that an in memory chef server would be handy. Then I found out about chef-zero, but I still wanted a project to learn Go, so I kept it up. Chef 11 Server also only runs under Linux at this time, while Goiardi is developed under Mac OS X and ought to run under any platform Go supports (only partially tested at this time though).

CONTRIBUTING

If you feel like contributing, great! Just fork the repo, make your improvements, and submit a pull request. Tests would, of course, be appreciated. Adding tests where there are no tests currently would be even more appreciated. At least, though, try and not break anything worse than it is. Test coverage has improved, but is still an ongoing concern.
