Just in case some folks aren’t exactly sure what a Swarm is, it’s basically a clustering of individual Docker hosts. They create what’s called a routing mesh, and instead…
The other day, I experienced an outage in my home data center. One of my Docker container hosts stopped working, and while most of its containers aren’t essential, one of them had an impact on a different system running on another server.
