To perform auto update, we use
watchtower. It
watches ap_operator container and check for the docker image update.
Once a new image is pushed to docker hub, watchtower pulls the new image,
then restarts the container that it momonitors with the new docker image.
Obviously this kind of update will only work when there is no config change required. If there is a configuration change that requires you to set a flag in the config, then we will need to perform a manually config change and then update.
However, we try hard to make the update painless and majority of time we can let it auto updated.
To run the auto update simply perform:
# make sure you're inside the `watchtower` directory.
# then bring up docker compose
docker compose up -d
you should see something like this
✔ Container watchtower Started
To check the log you can do:
docker compose logs -f
And it should show up like this:
❯ docker compose logs -f
