Agree with the article, but instead of Docker vs continuous delivery, I'd say learn about managing UNIX/Linux environments and reproducing these environments in other systems. Reproducing environments can be for CI, but also for dev, production, self-hosting, etc.
It can be with Docker, but also with lxc, chroot, virtual machines, scripts, etc. Generally, a common set of UNIX tools will stay useful in all contexts.
- olavgg 8y agoThe biggest failure I see with Docker is people not using the signal system in POSIX. Want to stop a container running a java application? You hit ctrl-c and send sigterm to the bash shell...not the java process. Or the default settings in Docker, you have a long running job in your java appliction, and you execute docker stop, which sends the correct sigterm, but after just 10 seconds it sends the sigkill signal. sigh
