Basically have watchtower monitor and update containers whenever new images are released. I’ve recently noticed that with searxng (using redis as db), hosted through nginx proxy manager, will have a steady downtime of about 15mins post update then come back online.
This is extremely frequent for searxng’s case as I have watchtower run every day and my preferred way of running most of my containers is with the latest tag. The way out of this downtime in my experience is a restart of NPM which brings back the searxng service.
I’m looking for a way to automate a restart of the NPM container after a successful update of searxng’s container.
I have checked the docs for watchtower, and the lifecycle hooks (a way to run sh scripts pre/post update) are able to run only from the applied container and not from the host system.
Either use depends_on or think of a health check and use Will Farrell’s simple Docker Autoheal container that restarts containers when they become unhealthy.
