Hello everyone. Is there a best practice or some workflow for doing rollbacks in AWS/Spryker Cloud environment? Rolling back the code base to a previous version is just a matter of creating containers from some older images, but what is the right (or the best) way to roll back database, redis and elasticsearch?

    We are currently just finishing up the documentation. Should be ready for release shortly

    Here is a preliminary version I can share with you. The final version will be published in our documentation sometime next week.

    thx,
    this is just a documentation how to restore a database backup.
    I'm more interested in rolling back a deployment without deleting data. When restoring the backup, things like e.g. orders or new customer accounts that happened in the meantime will be deleted

    Hi Philipp,

    There are 2 different options, what is possible to rollback, actually 3 when needed:
    1. DB: using a previously created snapshot you can restore the whole DB (structure + data)
    2. Application: using a deploy function with a dedicated version (GitHub commit)
    3. Do steps 1 and 2 simultaneously
    It sounds to me you are asking about the 2nd step and it is covered in the documentation here: https://cloud.spryker.com/docs/deploying-in-a-production-environment#roll-back-an-application

    Could you please check it and let us know if that is what you are looking for?
    Thank you.

    P.S. there is no backup and this restore solutions for redis, ES at the moment.

    We treat the DB as a single source of truth. Thus, there are solutions to backup and restore:
    1. data in database (backup and restore RDS)
    2. application or code (deploy a specific version).
    Everything else should be updated from these 2 places: DB or code of application.
    With backups of many interconnected pieces a new problem would need to be solved: keep all moving part in a consistency, when backed up and when restored.

    So basically suggested way to go is to
    • deploy older docker image
    • restore a db from a snapshot and then run data sync to sync the data with ES and redis
    Is there a reason why aren’t you suggesting the Propel Migrations? This seems to me a better way to revert the database structure without loosing the data.
    If we restore the DB from a snapshot, it would mean that we lose potential data saved since last snapshot (max 1 hour in this case), which, in a high traffic shop, would mean a large potential loss.

    Propel Migrations are also possible, but requires code changes.
    With RDS backup/restore no code changes are needed, as only AWS services need to be triggered.
    It is just a different approach.

    RDS Backup & Restore is of cause the "easier" way, but as Neven wrote, there will be a loss of data, which doesn't sound too cool
