> Docker doesn't require boiling the oceans.
Look, this is from a Windows perspective but I totally get this pro of Docker. I am the last line of defense at my company when stuff goes wrong and the sheer amount of variables that customer environments introduce is frightening. In one case, some HP server management solution changed a benign environment variable to something strange; completely breaking MSBuild (which we used heavily at the time). It took weeks to escalate to me, and hours in a meeting and ILSpy figuring out what was going wrong. Oceans we're boiled by burning money.
Docker is plug-and-play. We can mandate that customers can't futz with our image. Our software becomes an appliance that plugs into their network. We can upgrade from known states, with no HP BS throwing a spanner in the works. I am pushing it heavily for on-prem for this reason.
That answers the question cleanly: stupid stuff that happens on customer environments. Don't get me started on how much this lifts off of the ops team - our Docker stuff isn't yet in production but ops are salivating over it. There is no installer to run, no xcopy, you just ask Kube to give you an upgraded cluster.
I strongly suspect change aversion here. Nobody likes their cheese being moved.
