What does it do?
The package provides additional tasks for deployer (deployer.org) for synchronizing databases between instances. Most useful are two tasks:
- task "db:pull [source-instance]" task which allows you to pull database from source instance to current instance,
- task "db:copy [source-instance] [target-instance]" which allows to copy database between instances.
NOTE! Its tested only with Deployer 4.3.1!
Installation
Install package with composer:
composer require sourcebroker/deployer-extended-database
If you are using deployer as composer package then just put following line in your deploy.php:
new \SourceBroker\DeployerLoader\Load([['path' => 'vendor/sourcebroker/deployer-extended-database/deployer']]);
If you are using deployer as phar then put following lines in your deploy.php:
require_once(__DIR__ . '/vendor/sourcebroker/deployer-loader/autoload.php'); new \SourceBroker\DeployerLoader\Load([['path' => 'vendor/sourcebroker/deployer-extended-database/deployer']]);
IMPORTANT NOTE!Do not putrequire('/vendor/autoload.php')
inside your deploy.php because you can have dependency problems. Userequire_once(__DIR__ . '/vendor/sourcebroker/deployer-loader/autoload.php');
instead as suggested.Create ".env" file in your project root (where you store deploy.php file). The .env file should be out of git because you need to store here information about instance name. Additionally put there info about database you want to synchronise. You can move the info about database data to other file later but for the tests its better to put it in .env file. Remember to protect .env file from downloading with https request.
INSTANCE="local" DATABASE_HOST="127.0.0.1" DATABASE_NAME="database_name" DATABASE_USER="database_user" DATABASE_PASSWORD="password"
The INSTANCE must correspond to server() name. You need to put the .env file with proper INSTANCE name and database access data on on each of you instances.
Define "local" server and set the "db_databases" for it. Use following code:
(new \SourceBroker\DeployerExtendedDatabase\Driver\EnvDriver())->getDatabaseConfig()
which will read database data from .env file.
server('local', 'localhost') ->set('deploy_path', getcwd()) ->set('db_databases', [ 'database_default' => [ (new \SourceBroker\DeployerExtendedDatabase\Driver\EnvDriver())->getDatabaseConfig() ] ])
Add "db_databases" var for all other servers. For example for live server it can be:
server('live', 'my-server.example.com') ->user('deploy') ->set('deploy_path', '/var/www/myapplication/') ->set('db_databases', [ 'database_default' => [ (new \SourceBroker\DeployerExtendedDatabase\Driver\EnvDriver())->getDatabaseConfig() ] ])
Make sure all instances have the same /vendors folder with deployer-extended-database and the same deploy.php file. Most problems are because of differences in deploy.php file between instances.
Run
dep db:pull live
to test if all works.
Options
- db_databasesdefault value: nullDatabases to be synchronized. You can define more than one database to be synchronized. See db_databases for options available inside db_databases. Look for Examples for better understanding of structure.
- db_storage_path_relativedefault value: .dep/database/dumpsPath relative to "deploy_path" where you want to store database dumps produced during database synchro commands.
Options for "db_databases"
"db_databases" is an array of "database configurations" and "database configuration" is array of configuration parts. Configuration part can be array or string. If its string then its treated as absolute path to file which should return array of configuration. Each or array configuration parts is merged. Look for Examples for better understanding.
- hostdefault value: nullDatabase host.
- userdefault value: nullDatabase user.
- passworddefault value: nullDatabase user password.
- dbnamedefault value: nullDatabase name.
- truncate_tablesdefault value: nullArray of tables names that will be truncated with task db:truncate. Usually it should be some caching tables that will be truncated while deployment. The value is put between ^ and $ and treated as preg_match. For example you can write "cf_.*" to truncate all tables that starts with "cf_". The final preg_match checked is /^cf_.*$/i
- ignore_tables_outdefault value: nullArray of tables names that will be ignored while pulling database from target instance with task db:pull The value is put between ^ and $ and treated as preg_match. For example you can write "cf_.*" to truncate all tables that starts with "cf_". The final preg_match checked is /^cf_.*$/i
- post_sql_indefault value: nullSQL that will be executed after importing database on current instance.
- post_sql_in_markersdefault value: nullSQL that will be executed after importing database on current instance. The diffrence over "post_sql_in" is that you can use some predefined markers. For now only marker is {{domainsSeparatedByComma}} which consist of all domains defined in
->set('public_urls', ['https://live.example.com']);
and separated by comma. Having such marker allows to change active domain in database after import to other instance as some frameworks keeps domain names in database.
Examples
Below examples should illustrate how you should build your database configuration.
Config with one database and database data read from .env file
deploy.php file:
set('db_defaults', [ 'ignore_tables_out' => [ 'caching_*' ] ]); server('live', 'my-server.example.com') ->user('deploy') ->set('deploy_path', '/var/www/myapplication') ->set('db_databases', [ 'database_foo' => [ get('db_defaults'), (new \SourceBroker\DeployerExtendedDatabase\Driver\EnvDriver())->getDatabaseConfig() ], ] ); server('local', 'localhost') ->set('deploy_path', getcwd()) ->set('db_databases', [ 'database_foo' => [ get('db_defaults'), (new \SourceBroker\DeployerExtendedDatabase\Driver\EnvDriver())->getDatabaseConfig() ], ] );
Mind that because the db_* settings for all server will be the same then you can make the 'db_databases' setting global and put it out of server configurations. Look for below example where we simplified the config.
deploy.php file:
set('db_databases', [ 'database_foo' => [ 'ignore_tables_out' => [ 'caching_*' ] (new \SourceBroker\DeployerExtendedDatabase\Driver\EnvDriver())->getDatabaseConfig() ], ] ); server('live', 'my-server.example.com') ->user('deploy') ->set('deploy_path', '/var/www/myapplication/'); server('local', 'localhost') ->set('deploy_path', getcwd());
The .env file should look then like:
INSTANCE="[instance name]" DATABASE_HOST="127.0.0.1" DATABASE_NAME="database_name" DATABASE_USER="database_user" DATABASE_PASSWORD="password"
Config with two databases and database data read from .env file
deploy.php file:
set('db_databases', [ 'database_application1' => [ 'ignore_tables_out' => [ 'caching_*' ] (new \SourceBroker\DeployerExtendedDatabase\Driver\EnvDriver())->getDatabaseConfig('APP1_') ], 'database_application2' => [ 'ignore_tables_out' => [ 'cf_*' ] (new \SourceBroker\DeployerExtendedDatabase\Driver\EnvDriver())->getDatabaseConfig('APP2_') ], ] ); server('live', 'my-server.example.com') ->user('deploy') ->set('deploy_path', '/var/www/myapplication/'); server('local', 'localhost') ->set('deploy_path', getcwd());
The .env file should look then like:
INSTANCE="[instance name]" APP1_DATABASE_HOST="127.0.0.1" APP1_DATABASE_NAME="database_name" APP1_DATABASE_USER="database_user" APP1_DATABASE_PASSWORD="password" APP2_DATABASE_HOST="127.0.0.1" APP2_DATABASE_NAME="database_name" APP2_DATABASE_USER="database_user" APP2_DATABASE_PASSWORD="password"
Config with one database and database config read from from different sources
In example we will use:
array,
'ignore_tables_out' => [ 'caching_*' ]
get() which returns array with database options,
get('db_default')
direct file include which returns array with database options
__DIR__ . '/databases/conifg/additional_db_config.php
class/method which returns array with database options
(new \YourVendor\YourPackage\Driver\MyDriver())->getDatabaseConfig()
closure which returns array with database options
function() { return (new \YourVendor\YourPackage\Driver\MyDriver())->getDatabaseConfig()
}
Each of this arrays are merged to build final configuration for database synchro.
deploy.php file:
set('db_default', [ 'post_sql_in' => 'UPDATE sys_domains SET hidden=1;' ]); set('db_databases', [ 'database_foo' => [ 'ignore_tables_out' => [ 'caching_*' ] get('db_default'), __DIR__ . '/databases/conifg/additional_db_config.php (new \YourVendor\YourPackage\Driver\MyDriver())->getDatabaseConfig(), function() { return (new \YourVendor\YourPackage\Driver\MyDriver())->getDatabaseConfig() } ], ] ); server('live', 'my-server.example.com') ->user('deploy') ->set('deploy_path', '/var/www/myapplication/'); server('local', 'localhost') ->set('deploy_path', getcwd());
Config with one database and database config read from "my framework" file
Its advisable that you create you own special method that will return you framework database data. In below example
its call to \YourVendor\YourPackage\Driver\MyDriver()
. This way you do not need to repeat the data of database
in .env file. In that case .env file should hold only INSTANCE.
set('db_databases', [ 'database_default' => [ (new \YourVendor\YourPackage\Driver\MyDriver())->getDatabaseConfig() ], ] );
Config of truncate_tables, ignore_tables_out, post_sql_in_markers
Real life example for CMS TYPO3:
set('db_default', [ 'truncate_tables' => [ 'cf_.*' ], 'ignore_tables_out' => [ 'cf_.*', 'cache_.*', 'be_sessions', 'fe_sessions', 'sys_history', 'sys_file_processedfile', 'sys_log', 'sys_refindex', 'tx_devlog', 'tx_extensionmanager_domain_model_extension', 'tx_realurl_chashcache', 'tx_realurl_errorlog', 'tx_realurl_pathcache', 'tx_realurl_uniqalias', 'tx_realurl_urldecodecache', 'tx_realurl_urlencodecache', 'tx_powermail_domain_model_mails', 'tx_powermail_domain_model_answers', 'tx_solr_.*', 'tx_crawler_queue', 'tx_crawler_process', ], 'post_sql_in_markers' => 'UPDATE sys_domain SET hidden = 1; UPDATE sys_domain SET sorting = sorting + 100; UPDATE sys_domain SET sorting = 1, hidden = 0 WHERE domainName IN ({{domainsSeparatedByComma}});' ]);
Tasks
db:backup
Backup database. In background, on target instance, two tasks are executed 'db:export' and 'db:compress'. Results are stored in "{{deploy_path}}/.dep/databases/dumps/". If no target is given the it will be done on current instance.
If releases folder will be detected then it adds info about release in dumpcode name like in this example:
2017-12-04_00:20:22#server=live#dbcode=database_default#dumpcode=backup_for_release_160_ec77cb6bc0e941b0ac92e2109ad7b04e#type=structure.sql.gz
Example
dep db:backup dep db:backup live dep db:backup live --dumpcode=mycode
db:compress
Compress dumps with given dumpcode stored in folder "{{deploy_path}}/.dep/databases/dumps/" on target instance. If no target is given the it will compress dumps on current instance. There is required option --dumpcode to be passed.
Look for config vars 'db_compress_suffix', 'db_compress_command', 'db_uncompress_command' for possible ways to overwrite standard gzip compression with your own.
Example
dep db:compress live --dumpcode=0772a8d396911951022db5ea385535f6
db:copy
This command allows you to copy database between instances.
dep db:copy [source-instance] [target-instance]
In the background it runs several other tasks to accomplish this. Lets assume we want to copy database from live to dev instance. We will run following command on you local current (in out exmaple local instance):
dep db:copy live dev
Here are the tasks that will be run in background:
- In below description:
- source instance = live
- target instance = dev
- current instance = local
- First it runs
dep db:export --dumpcode=123456
task on source instance. The dumps from export task are stored in folder "{{deploy_path}}/.dep/databases/dumps/" on target instance. - Then it runs
db:download live --dumpcode=123456
on current instance to download dump files from live instance from folder "{{deploy_path}}/.dep/databases/dumps/" to current instance to folder "{{deploy_path}}/.dep/databases/dumps/". - Then it runs
db:process --dumpcode=123456
on current instance to make some operations directly on SQL dumps files. - Then it runs
db:upload dev --dumpcode=123456
on current instance. This task takes dump files with code:123456 and send it to dev instance and store it in folder "{{deploy_path}}/.dep/databases/dumps/". - Finally it runs
db:import --dumpcode=123456
on target instance. This task reads dumps with code:123456 from folder "{{deploy_path}}/.dep/databases/dumps/" on dev instance and import it to database. - At the very end it removes dumps it just imported in step 5 with command
db:rmdump --dumpcode=123456
db:decompress
Decompress dumps with given dumpcode stored in folder "{{deploy_path}}/.dep/databases/dumps/" on target instance. If no target is given the it will compress dumps on current instance. There is required option --dumpcode to be passed.
Look for config vars 'db_compress_suffix', 'db_compress_command', 'db_uncompress_command' for possible ways to overwrite standard gzip compression with your own.
Example
dep db:decompress live --dumpcode=0772a8d396911951022db5ea385535f6
db:download
Download database dumps with selected dumpcode from folder "{{deploy_path}}/.dep/databases/dumps/" on target instance and store it in folder "{{deploy_path}}/.dep/databases/dumps/" on current instance. There is required option --dumpcode to be passed.
Example
dep db:download live --dumpcode=0772a8d396911951022db5ea385535f6
db:dumpclean
Clean database dump storage on target instance (or on current instance if target instance is not set). By default it removes all dumps except last five but you can set your values and also change the values depending on instance.
Example
set('db_dumpclean_keep', 10); // keep last 10 dumps for all instances set('db_dumpclean_keep', [ 'live' => 10 // keep last 10 dumps for live instance dumps 'dev' => 5 // keep last 5 dumps for dev instance dumps '*' => 2 // keep last 5 dumps for all other instances dumps ]); dep db:dumpclean live
db:export
Dump database to folder on current instance located by default in "{{deploy_path}}/.dep/databases/dumps/". Dumps will be stored in two separate files. One with tables structure. The second with data only. There is option --dumpcode that can be passed. If there is no dumpcode then its created and returned as json structure.
Example
Example task call:
dep db:export
Example output files located in folder {{deploy_path}}/.dep/databases/dumps/:
2017-02-26_14:56:08#server=live#dbcode=database_default#type=data#dumpcode=362d7ca0ff065f489c9b79d0a73720f5.sql 2017-02-26_14:56:08#server=live#dbcode=database_default#type=structure#dumpcode=362d7ca0ff065f489c9b79d0a73720f5.sql
Example task call with own dumpcode=
dep db:export --dumpcode=mycode
Example output files:
2017-02-26_14:56:08#server=live#dbcode=database_default#type=data#dumpcode=mycode.sql 2017-02-26_14:56:08#server=live#dbcode=database_default#type=structure#dumpcode=mycode.sql
db:import
Import database dump files from current instance folder "{{deploy_path}}/.dep/databases/dumps/" to current database(s). There is required option --dumpcode to be passed.
Example
dep db:import --dumpcode=0772a8d396911951022db5ea385535f66
db:process
This command will run some defined commands on pure sql file as its sometimes needed to remove or replace some strings directly on sql file before importing. There is required option --dumpcode to be passed.
Example
dep db:process --dumpcode=0772a8d396911951022db5ea385535f66
db:pull
This command allows you to pull database from target instance to current instance. In the background it runs several other tasks to accomplish this.
Here is the list of tasks that will be done afer "db:pull":
- First it runs db:export task on target instance and get the "dumpcode" as return to use it in next commands.
- Then it runs db:download on current instance (with "dumpcode" value from first task).
- Then it runs db:process on current instance (with "dumpcode" value from first task).
- Then it runs db:import on current instance (with "dumpcode" value from first task).
Example
dep db:pull live
db:rmdump
This command will remove all dumps with given dumpcode (compressed and uncompressed). There is required option --dumpcode to be passed.
Example
dep db:rmdump live --dumpcode=0772a8d396911951022db5ea385535f66
db:truncate
This command allows you to truncate database tables defined in database config var "truncate_tables". No dumpcode is needed because it operates directly on database.
Example Truncate current instance databases tables.
dep db:truncate
Truncate live instance databases tables.
dep db:truncate live
db:upload
Upload database dumps with selected dumpcode from folder "{{deploy_path}}/.dep/databases/dumps/" on current instance and store it in folder "{{deploy_path}}/.dep/databases/dumps/" on target instance. There is required option --dumpcode to be passed.
Example
dep db:upload live --dumpcode=0772a8d396911951022db5ea385535f6
