Everyone is talking about Docker, but you already have a day job and spend your nights learning three other new technologies. Plus the kids need a story before bed, the toilet won’t flush right, the trash needs gathering up and – who has the time?! Don’t worry, we’ve got you covered! I can’t help with the plumbing, but we here at Linux Academy and Cloud Assessments can give you a head start on Docker and maybe even save you a few minutes by using it.
Docker has been touted as a “lighter visor,” and I’m still not sure how I feel about that. On the one hand, it’s correct: Docker containers are, in many ways, similar to virtual machines in that they are discrete units of compute designed around an application or set of applications making up a task. Besides being an order of magnitude more efficient by making use of the host’s kernel, containers are smaller, faster, and generally better for many tasks than virtual machines.
