How can I monitor a private git docker repositry.

Hi,

We are publishing the docker images as packages to the docker github registry (docker.pkg.github.com). How can I use the watch tower to monitor the image on this registry?

Thanks

Hi!

Just as you would any other registry. Just make sure you launch your containers using their fully qualified vanity-url, for instance: docker.pkg.github.com/usman557/your-project/your-repo:latest

Best,

Thanks for the reply @simskij but that is exactly what I am doing but the latest image is not being pulled down. Below is the details.

Command to run docker image:

docker run docker.pkg.github.com/usman557/consoleapp1/consoleapp1:master

Command to watch the container:

docker run -d --name watchtower -e REPO_USER=USERNAME -e REPO_PASS=PASSWORD -v /var/run/docker.sock:/var/run/docker.sock containrrr/watchtower docker.pkg.github.com/usman557/consoleapp1/consoleapp1:master --debug --trace --interval 10

I am not getting the latest changes that I am making to my docker image. Can you please let me know what I am missing here?

Command to watch the container:

docker run -d --name watchtower -e REPO_USER=USERNAME -e REPO_PASS=PASSWORD -v
/var/run/docker.sock:/var/run/docker.sock containrrr/watchtower 
docker.pkg.github.com/usman557/consoleapp1/consoleapp1:master --debug --trace --interval 10

If you want to do selective monitoring, then docker.pkg.github.com/usman557/consoleapp1/consoleapp1:master needs to be switched to the name of the container, rather than the full URL of the image. For instance:

 $ docker run --name console docker.pkg.github.com/usman557/consoleapp1/consoleapp1:master
 $ docker run -d \
      --name watchtower \
      -e REPO_USER=USERNAME \
      -e REPO_PASS=PASSWORD \
      -v /var/run/docker.sock:/var/run/docker.sock \
      containrrr/watchtower \
      console \
      --debug \
      --trace \
      --interval 10

If you'd rather have watchtower monitor everything in your docker instance, just remove that part altogether:

 $ docker run -d \
      --name watchtower \
      -e REPO_USER=USERNAME \
      -e REPO_PASS=PASSWORD \
      -v /var/run/docker.sock:/var/run/docker.sock \
      containrrr/watchtower \
      --debug \
      --trace \
      --interval 10

Do I really need REPO_USER and REPO_PASS? I don't want to provide my username and password in my docker-compose file. I want to use $HOME/.docker/config.json that gets generated after login based on their instructions using personal token.

@samru-rai yeah, that is the usual way of doing it. As long as you use the full image name for the docker image it should work with a mounted docker config.
