Pulling new images for custom apps deployed via yaml

Apps and Virtualization
1

I have successfully deployed the FOUNDRY VTT app via a YAML script (included compose.yml). The app is telling me that a new version is available and that I should pull a new Docker image. On a PC, I would issue the docker compose down command followed by the docker compose pull command (while being in the directory where the compose.yml file is stored. When I tried issuing the command from an SSH session, I get permission denied. Is there a better way for me to do this? FYI I do have portainer loaded on the system as well but it doesn’t look like I can selectively PULL images. Any thoughts or suggestions would be appreciated! Thanks

Maybe i misurunderstood your question, but with Portainer, if you enter your app stack and press update, a popup will ask you if you want pull the new image too… Have you tried?

Just to mention, if can be interesting for your use case, Is possible to automate this process deploing watchtower app and adding this label

    labels:
      - "com.centurylinklabs.watchtower.enable=true"

on specific app (using image latest). For no-critical app Is very usefull IMHO

I have not tried what you suggested. I’m a novice with TrueNAS and portainer, so just uncovering “possible” fixes is helpful. Let me test this out! Thanks!
