Setup

By default, watchtower will monitor all containers

docker run -d \
    -v /var/run/docker.sock:/var/run/docker.sock \
    --name Watchtower \
    containrrr/watchtower

If you want to specify specific containers to monitor, add extra parameters

docker run -d \
    -v /var/run/docker.sock:/var/run/docker.sock \
    --name Watchtower \
    containrrr/watchtower \
    ESPHome

You can also specify containers to be automatically updated based on label. To enable a container to update, set the container label com.centurylinklabs.watchtower.enable to true

docker run -d \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -e WATCHTOWER_LABEL_ENABLE=true \
    --name Watchtower \
    containrrr/watchtower
