Brief about Chef Private Supermarket

Configuration

All of the Chef Supermarket's non-default configuration parameters are stored in the supermarket.rb file. Only non-default values should be added to the supermarket.rb file because the default values are already included in the Chef Supermarket setup. The supermarket-ctl reconfigure command applies these configuration settings. Since the supermarket.rb file is a Ruby file, the configuration file can contain conditional statements.

Backup and Restore

Frequent Backup is required to ensure we don’t lose any important files or data. We can backup supermarket data frequently and then restore it later.

Let’s look at how we can backup the database and cookbook.

CookBook Backup

It is necessary to back up the local cookbook storage location on the Supermarket server if Supermarket is not set up to use AWS S3 storage for cookbooks.

/var/opt/supermarket/data/cookbook versions is the default location.

Use the below-mentioned commands to backup the cookbook.

cd /var/opt/supermarket/data/
tar cvzf ~/supermarket_cookbook_versions.tar.gz cookbook_versions

Database Backup

There are various formats available for database exports. For example, the following syntax can be used to create a database export in the .dump format:

/opt/supermarket/embedded/bin/pg_dump --host localhost --username supermarket --dbname supermarket --port 15432 --format c --blobs --verbose --file ~/supermarket_database_backup.dump

After backing up data, Now it’s time to restore the data.

Cookbook Restore

When restoring cookbooks, confirm that the Supermarket user has permission to write to the cookbook directory.
To restore your cookbook files, run the following command:

cd /var/opt/supermarket/data/
tar xvzf /supermarket_cookbook_versions.tar.gz

Database Restore

Backups cannot be transferred between Supermarket versions using the restore feature. Backups must be restored to the same Supermarket version that was in use when they were made.

Use the following command to restore the database:

/opt/supermarket/embedded/bin/pg_restore --username supermarket --host localhost --port 15432 --clean --no-acl --no-owner --dbname supermarket --verbose ~/supermarket_database_backup.dump

Other Things can also be done in the private supermarket, like monitoring supermarket, Supermarket logs, and lastly, we can always upgrade to the latest version of the supermarket.
