Kiln helps you maintain tile metadata.

Kiln

Kiln bakes tiles

Kiln helps tile developers build products for Pivotal Operations Manager. It provides an opinionated folder structure and templating capabilities. It is designed to be used both in CI environments and in command-line to produce a tile.

Subcommands

bake

It takes release and stemcell tarballs, metadata YAML, and JavaScript migrations as inputs and produces an OpsMan-compatible tile as its output.

Here is an example command line:

$ kiln bake \
    --version 2.0.0 \
    --metadata /path/to/metadata.yml \
    --releases-directory /path/to/releases \
    --stemcell-tarball /path/to/stemcell.tgz \
    --migrations-directory /path/to/migrations \
    --output-file /path/to/cf-2.0.0-build.4.pivotal

Refer to the example-tile for a complete example showing the different features kiln supports.

Options

--bosh-variables-directory

The --bosh-variables-directory flag can be used to include CredHub variable declarations. You should prefer the use of variables rather than Ops Manager secrets. Each .yml file in the directory should define a top-level variables key.

This flag can be specified multiple times if you have organized your variables into subdirectories for development convenience.

Example variables directory.

--embed

The --embed flag is for embedding any extra files or directories into the tile. There are very few reasons a tile developer should want to do this, but if you do, you can include these extra files here. The flag can be specified multiple times to embed multiple files or directories.

--forms-directory

The --forms-directory flag takes a path to a directory that contains one or more forms. The flag can be specified more than once.

To reference a form file in the directory you can use the form template helper:

$ cat /path/to/metadata
---
form_types:
- $( form "first" )

Example forms directory.

--icon

The --icon flag takes a path to an icon file.

To include the base64'd representation of the icon you can use the icon template helper:

$ cat /path/to/metadata
---
icon_image: $( icon )

--instance-groups-directory

The --instance-groups-directory flag takes a path to a directory that contains one or more instance groups. The flag can be specified more than once.

To reference an instance group in the directory you can use the instance_group template helper:

$ cat /path/to/metadata
---
job_types:
- $( instance_group "my-instance-group" )

Example instance-groups directory.

--jobs-directory

The --jobs-directory flag takes a path to a directory that contains one or more jobs. The flag can be specified more than once.

To reference a job file in the directory you can use the job template helper:

$ cat /path/to/instance-group
---
templates:
- $( job "my-job" )
- $( job "my-aliased-job" )
- $( job "my-errand" )

Example jobs directory.

You may find that you want to define different job files for the same BOSH job with different properties. To do this you add an alias key to the job which will be used in preference to the job name when resolving job references:

$ cat /path/to/my-aliased-job
---
name: my-job
alias: my-aliased-job

--metadata

Specify a file path to a tile metadata file for the --metadata flag. This metadata file will contain the contents of your tile configuration as specified in the OpsManager tile development documentation.

--metadata-only

Output the generated metadata to stdout. Cannot be used with --output-file.

--migrations-directory

If your tile has JavaScript migrations, then you will need to include the --migrations-directory flag. This flag can be specified multiple times if you have organized your migrations into subdirectories for development convenience.

--output-file

The --output-file flag takes a path to the location on the filesystem where your tile will be created. The flag expects a full file name like tiles/my-tile-1.2.3-build.4.pivotal.

Cannot be used with --metadata-only.

--properties-directory

The --properties-directory flag takes a path to a directory that contains one or more blueprint property files. The flag can be specified more than once.

To reference a properties file in the directory you can use the property template helper:

$ cat /path/to/metadata
---
property_blueprints:
- $( property "rep_password" )

Example properties directory.

--releases-directory

The --releases-directory flag takes a path to a directory that contains one or many release tarballs. The flag can be specified more than once. This is useful if you consume bosh releases as Concourse resources. Each release will likely show up in the task as a separate directory. For example:

$ tree /path/to/releases
|-- first
|   |-- cflinuxfs2-release-1.166.0.tgz
|   `-- consul-release-190.tgz
`-- second
    `-- nats-release-22.tgz

To reference a release you can use the release template helper:

$ cat /path/to/metadata
---
releases:
- $( release "cflinuxfs2" )
- $( release "consul" )
- $( release "nats" )

Example kiln command line:

$ kiln bake \
    --version 2.0.0 \
    --metadata /path/to/metadata.yml \
    --releases-directory /path/to/releases/first \
    --releases-directory /path/to/releases/second \
    --stemcell-tarball /path/to/stemcell.tgz \
    --output-file /path/to/cf-2.0.0-build.4.pivotal

--runtime-configs-directory

The --runtime-configs-directory flag takes a path to a directory that contains one or more runtime config files. The flag can be specified more than once.

To reference a runtime config in the directory you can use the runtime_config template helper:

$ cat /path/to/metadata
---
runtime_configs:
- $( runtime_config "first-runtime-config" )

Example runtime-configs directory.

--stemcell-tarball

The --stemcell-tarball flag takes a path to a stemcell.

To include information about the stemcell in your metadata you can use the stemcell template helper:

$ cat /path/to/metadata
---
stemcell_criteria: $( stemcell )

--stub-releases

For tile developers looking to get some quick feedback about their tile metadata, the --stub-releases flag will skip including the release tarballs into the built tile output. This should result in a much smaller file that should upload much more quickly to OpsManager.

--variable

The --variable flag takes a key=value argument that allows you to specify arbitrary variables for use in your metadata. The flag can be specified more than once.

To reference a variable you can use the variable template helper:

$ cat /path/to/metadata
---
$( variable "some-variable" )

--variables-file

The --variables-file flag takes a path to a YAML file that contains arbitrary variables for use in your metadata. The flag can be specified more than once.

To reference a variable you can use the variable template helper:

$ cat /path/to/metadata
---
$( variable "some-variable" )

Example variables file.

--version

The --version flag takes the version number you want your tile to become.

To reference the version you use the version template helper:

$ cat /path/to/metadata
---
product_version: $( version )
provides_product_versions:
- name: example
  version: $( version )

Template functions

select

The select function allows you to pluck values for nested fields from a template helper.

For instance, this section in our example tile:

my_release_version: $( release "my-release" | select "version" )

Results in:

my_release_version: 1.2.3
