Updating a Docker Mirror image

[technofab]

Mmhmm great, so what you suggest? Backup config and modules delete all, reinstall container and restore config and modules?

[sdetweil]

@technofab well, TRY it…

[technofab]

For now I suppose this scenario:

docker stop magic_mirror
docker rm magic_mirror
docker system prune -a -f
docker run -d --publish 80:8080 --restart always…

In this way I suppose that after run is completed is full updated.

@technofab looks like docker added a new flag to handle some of this

on docker run

--pull=[always,*missing,never]

I think there should have been ‘updated’ too

so add

--pull=always

then u don’t need the other steps

[technofab]

I don’t know that switch! But it read from dockerfile? My strategy is a bit longer but it can guarantee that all is updated and I can also add git pull for every module in the sequence…

Edit: I give a try, but not works, and didn’t find that on documentation.
