At the end of 2021, a new version of Rancher Desktop came out that provides the Docker CLI and a dockerd socket as an alternative to nerdctl and containerd. In this post I’ll cover some details on why and how we did it.
When I recently bought a Framework laptop, one of the tasks I needed to do was to choose a processor. When I bought Mac computers there were few things to think about in terms of processors. A more expensive processor just meant more power. The processors available in Framework laptops don’t quite operate on that model. In some cases, you may get more features and not more power. Are those features you want? That’s the question I asked myself.
It was time to replace my 7 year old Macbook Pro. Two cores running the latest macOS was not longer capable of easily doing everything I threw at it. Instead of buying another Macbook Pro I went a different route. After close to 20 years of having a personal Mac laptop, I switched to a Framework laptop. This is the reasoning behind the move.
Almost everywhere I look, IT is treated as a cost center. Their goal is often to cut costs (expenses) to be as low as possible. But, this isn’t working well for them or the companies that treat things like this. In companies like this you end up with shadow IT, lines of business who are held back (which hurts income), or a little of both. Let’s explore what this means.
The Docker CLI has some competition in the form of podman and nerdctl. Recent changes in the Docker ecosystem have caused some folks to start looking at what the other options are. Since these are two of the most capable Docker CLI alternatives, it’s worth looking at them.
