The following recipes are exposed to consumers of capistrano-extensions. You’ll likely want to create custom recipes that group some of these together a la passenger-recipes . Also check out Properties and Code Extensions.
Creates shared filecolumn directories and symbolic links to them by reading the :content_directories property. Note that this task is not invoked by default, but rather is exposed to you as a helper. To utilize, you’ll want to override deploy:default and invoke this yourself. Invokes geminstaller to ensure that the proper gem set is installed on the target server. Note that this task is not invoked by default, but rather is exposed to you as a helper. Tarballs deployable environment’s rails logfile (identified by RAILS_ENV environment variable, which defaults to ‘production’) and copies it to the local filesystem Backs up deployable environment’s database (identified by the RAILS_ENV environment variable, which defaults to ‘production’) and copies it to the local machine Untars the backup file downloaded from local:backup_db (specified via the FROM env variable, which defaults to RAILS_ENV), and imports (via mysql command line tool) it back into the database defined in the RAILS_ENV env variable. ToDo: implement proper rollback: currently, if the mysql import succeeds, but the rm fails, the database won’t be rolled back. Not sure this is even all that important or necessary, since it’s a local database that doesn’t demand integrity (in other words, you’re still going to have to fix it, but it’s not mission critical). Downloads a tarball of uploaded content (that lives in public/ directory, as specified by the :content_directories property) from the production site back to the local filesystem Restores the backed up content (env var FROM specifies which environment was backed up, defaults to RAILS_ENV) to the local development environment app Wrapper for local:backup_db and local:restore_db $> cap local:sync_db RAILS_ENV=production RESTORE_ENV=development Wrapper for local:backup_content and local:restore_content $> cap local:sync_content RAILS_ENV=production RESTORE_ENV=development Wrapper for local:sync_db and local:sync_content $> cap local:sync RAILS_ENV=production RESTORE_ENV=development Uploads the backup file downloaded from local:backup_db (specified via the FROM env variable), copies it to the remove environment specified by RAILS_ENV, and imports (via mysql command line tool) it back into the remote database. Backs up target deployable environment’s database (identified by the FROM environment variable, which defaults to ‘production’) and restores it to the remote database identified by the TO environment variable, which defaults to “staging.” Because multiple capistrano configurations must be loaded, an external executable (capistrano-extensions-sync_db) is invoked, which independently calls capistrano. See the executable at $GEM_HOME/capistrano-extensions-0.1.3/bin/capistrano-extensions-sync_db $> cap remote:sync_db FROM=production TO=staging Uploads the backup file downloaded from local:backup_content (specified via the FROM env variable), copies it to the remote environment specified by RAILS_ENV, and unpacks it into the shared/ directory. Backs up target deployable environment’s shared content (identified by the FROM environment variable, which defaults to ‘production’) and restores it to the remote environment identified by the TO envrionment variable, which defaults to “staging.” Because multiple capistrano configurations must be loaded, an external executable (capistrano-extensions-sync_content) is invoked, which independently calls capistrano. See the executable at $GEM_HOME/capistrano-extensions-0.1.2/bin/capistrano-extensions-sync_content $> cap remote:sync_content FROM=production TO=staging Wrapper fro remote:sync_db and remote:sync_content. $> cap remote:sync FROM=production TO=staging
