Auto-Restarting Docker Containers

Andrew Pruski helps out those of us who can’t seem to let our containers go:

One of the problems that I’ve encountered since moving my Dev/QA departments to using SQL Server within containers is that the host machine is now a single point of failure.

Now there’s a whole bunch of posts I could write about this but the one point I want to bring up now is…having to start up all the containers after patching the host.

I know, I know…technically I shouldn’t bother. After patching and bouncing the host, the containers should all be blown away and new ones deployed. But this is the real world and sometimes people want to retain the container(s) that they’re working with.

It’s pretty easy to set up a restart policy, as Andrew shows.
