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.

    No worries. I ended up writing a systemd service that restarts the npm container a minute after the watchtower runs. I don’t know why I didn’t think of that earlier but I guess it’s a much simpler solution than using depends_on with npm which hosts a lot of my other services.
