Container selection

By default, watchtower will watch all containers. However, sometimes only some containers should be updated.

If you need to exclude some containers, set the com.centurylinklabs.watchtower.enable label to false.

LABEL com.centurylinklabs.watchtower.enable="false"

Or, it can be specified as part of the docker run command line:

docker run -d --label=com.centurylinklabs.watchtower.enable=false someimage

If you need to include only containers with the enable label, pass the --label-enable flag or the WATCTOWER_LABEL_ENABLE environment variable on startup and set the com.centurylinklabs.watchtower.enable label with a value of true for the containers you want to watch.

LABEL com.centurylinklabs.watchtower.enable="true"

Or, it can be specified as part of the docker run command line:

docker run -d --label=com.centurylinklabs.watchtower.enable=true someimage
