Upgrade from 0.36.6 to 0.37.x

Get Help
1

Hi friends!

I’m running metabase 36.6 on docker with a “custom container” as it is described here:

https://www.metabase.com/docs/latest/operations-guide/running-metabase-on-docker.html > under the heading “Getting your config back if you stopped your container”.

I connected a mysql database to this container and configured a lot of questions, dashboards.

If I’m understand it correctly the current application database is mysql, metabase made an own table in my mysql database.

If im correct: In order to upgrade to 37.3 I need application database config from the container and load it to an shared volume for 37.3. However I can not find it.

This command, leads to an empty metabase.db folder.

docker cp CONTAINER_ID:/metabase.db ./

I also search the active container via the bash and couldn’t find any databases.

Hi @megrano
Please post “Diagnostic Info” from Admin > Troubleshooting.
If you have configured MySQL as the application database, then all your Metabase data is stored there, and there will not be a H2 file in the container.

      "hash": "cb258fb"
    },
    "settings": {
      "report-timezone": null
    }
  }
}

I guess this means that the application database is mysql. But how do I upgrade to latetst? How do I tell the new metabase-lastest container to load from my mysql database?

@megrano You would remove your current container, update the image, and start a new container with the same environment variables as your current container.
https://www.metabase.com/docs/latest/operations-guide/upgrading-metabase.html

I did exactly this. But the new container started up with the empty h2 database. He didn’t recognize the mysql database as application database.

@megrano Post your docker run command (redact sensitive info)

Im running on docker-compose… can switch to docker run is necessary:

docker-compose.yml:

version: "3"

services:
  metabase:
    network_mode: host
    container_name: "metabase-lastest"
    restart: "unless-stopped"
    image: metabase/metabase
    env_file:
      - ./config/metabase_database.env

with the evn_file: metabase_database.env

ENV MB_DB_TYPE=mysql
ENV MB_DB_DBNAME=metabase
ENV MB_DB_PORT=3306
ENV MB_DB_USER=root
ENV MB_DB_PASS=XXXXXXXX
ENV MB_DB_HOST=localhost

ENV MB_ENCRYPTION_SECRET_KEY=XXXXXXXXXXX

@megrano Post the commands that you do to remove, update, and create new instance.

It’s simply docker-compose down, then I edit the docker-compose.yml file to the one I posted above. (I modify container_name and image).

After that docker-compose up.

Very simple.)

@megrano You should not use ENV in front of your variables: https://docs.docker.com/compose/env-file/
