running command inside container

[perler]

for an import script I want to run a bash command inside a (here: nextcloud..) container. This instruction to identify the container from the hostname doesn't seem to work anymore:

https://forum.cloudron.io/post/2011

what's the current approach?

The script mentioned in the other forum post should still work fine. At its core is the following docker cli line to detect the container id:

docker ps -q -f label=fqdn=$app -f label=isSubcontainer=false

The attributes it filters on have not changed since then.

Hi @perler

from the settings of the app on in the Cloudron dashboard you could open a terminal. which will give you access to the container.

You could also use the cloudron cli from your workstation. cloudron exec --app $locationofyournextcloud.

we want to use this in a script which runs locally on the cloudron server - what would be the preferred way here?

@perler is this a one off thing, or something to run on a regular base?

Personally I would use cloudron exec, but if you're planning to run the task regularly then it may be better to add this to the cron jobs of the app.

it's a one off thing, but preferrable within a script (so it should resolve the local container-id by hostname)

@perler Have you seen https://docs.cloudron.io/apps/#cron already? This will run the job in the context of a container.

I am happy to add other "meta" patterns, if none of those fit your use case
