Docker Deployment

This assumes that Postgres is physically installed on the machine. But what if I have both Strapi and Postgres running in docker containers. How do I get the plugin to see pg_dump

I actually tested postgres backup workflow using docker. All you need is the pgdump tool which is basically just a postgres client.

You can definitely have it without a whole PG install, see this thread for more : https://dba.stackexchange.com/questions/193023/pg-dump-without-postgresql

I plan to add configuration option where you would be able to give the path to pg_dump tool. With this new way you'd be able to bind directly pg_dump from postgres container using volumes.

@laportem release 0.5.1 is out with pg_dump path override.

You can now add to config/plugins.js

// config/plugins.js
module.exports = () => ({
  //...
  "backup-restore": {
    postgres: {
      // Update with your path
      pathToPgDump: "/usr/local/opt/libpq/bin/pg_dump",
    },
  },
});

If you want to keep your strapi image as it is now, you could bind pg_dump from postgres container. See https://phoenixnap.com/kb/how-to-share-data-between-docker-containers for more. Basically it's just about binding the tool to a path in strapi container and then use this path in strapi config.

thanks, will give it a try and feedback if issues

Got the backup to work ok. i see on your TODO list, restore is still in the pipeline. Until then can you advise on a restore progress

Could you guide on the same for restoring from dump for docker setup?

Sorry for late reply, I have actually no ETA for this. If anyone wants to submit a PR feel free to do it!

Since it's not yet implemented in this plugin you'd have to handle it manually. Using docker based install, you can achieve this using

# copy backup in your db container
docker cp my_data.dump postgres_container:/backups

docker exec postgres_container pg_restore -U postgres -d some_database /backups/my_data.dump

https://www.postgresqltutorial.com/postgresql-restore-database/

The same could be achieved for mysql, you just need to update exec command :

docker cp backup.sql postgres_container:/backups

docker exec postgres_container mysql -u [user] -p [database_name] < /backups/backup.sql
