Upgrade Arangodb - how to add a command line flag when running in Docker?

We deployed an arangodb docker instance on google compute engine, about 2 years ago.

It always worked fine and was never restarted until now. The arangodb was upgraded, but I can not upgrade the database. This is de compute engine log:

I can not add that --database.auto-upgrade true anywhere in compute engine (I tried in the environment variables section in the compute engine, but didn't seem to catch on).

I am able to login on the Microserver where the docker container is installed, but the container stops working almost immediately after startup, so I can not shell to a prompt to do the upgrade manually.

I can start the container with:

docker run -ti -u root --entrypoint=sh image_id_or_name -s

But the config or changes are not retained here. Any insights or suggestions ?

First of all, you need to know, what volumes or paths are mapped on instance created by compute engine, it's under Advanced container options

in terminal you can use https://github.com/nexdrew/rekcod, run following command, change <container> to id/name of your initial instance

docker run --rm -i -v /var/run/docker.sock:/var/run/docker.sock nexdrew/rekcod <container>

in output you should get something like

docker run --name arangodb --runtime runc -v arangodb--3.7:/var/lib/arangodb3 -v arangodb-apps--3.7:/var/lib/arangodb3-apps -p 8529:8529/tcp --restart no -h 0e989039f8c8 --expose 8529/tcp -e 'ARANGO_NO_AUTH=1' -e 'PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin' -e 'GLIBCXX_FORCE_NEW=1' -d --entrypoint "/entrypoint.sh" arangodb/arangodb:3.7.5 'arangod'

-v arguments are those you'll need to add when you run backup and upgrade

before upgrade create backup with following command, if you have default config, then you need backup /var/lib/arangodb3, change <volume> to volume/path according to output in previous step

docker run --rm -v /tmp:/backup -v <volume>:/var/lib/arangodb3 busybox tar -zcvf /backup/arangodb3.tar.gz /var/lib/arangodb3

that gonna create data backup /tmp/arangodb3.tar.gz on your host machine, keep that.

if you'll need restore you can run

docker run --rm -v <volume>:/var/lib/arangodb3 -v /tmp:/backup busybox tar -xzvf /backup/arangodb3.tar.gz var/lib/arangodb3

WARNING: as per General Upgrade Information / Upgrade Paths

you'll need to upgrade your 3.5.3 in multiple steps

  1. first to 3.5.7
  2. second to 3.6.13
  3. last to 3.7.11

to upgrade run following command, change <volume> to volume/path according to output in previous step, change <arango-image> to target arangodb image version

docker run -v <volume>:/var/lib/arangodb3 <arango-image> arangod --database.auto-upgrade=true

then start arangodb in compute engine
