In some cases, I need to restart other containers after deunhealth restarts the one with the deunhealth.restart.on.unhealthy label.
In order to do this, I added a new label deunhealth.restart.with.unhealthy.container which should be applied on containers which must be restarted after deunhealth restarts a monitored one. The value of the label should refer to a deunhealth monitored container.
Ex:
Container_1 has the label deunhealth.restart.on.unhealthy=true
Container_2 has the label deunhealth.restart.with.unhealthy.container=Container_1
When Container_1 gets unhealthy, deunhealth will restart it, and will restart Container_2 afterward:
