This works for one Go or Rust executable but any real system is a mix of technologies e.g A Go service talking to a Java application server proxied with a C webserver that was configured with a bash script.

Once you have a mix of different technologies its easier to just say "everything in Docker".

The ship container analogy on the old Docker website was a great illustration of this. Its a shame the new website is not so clear about the benefits and is full empty phrases such as "accelerating innovation".

Does it even work well for go or rust executables? I seem to recall that Docker itself was written in golang because "fat binaries1111", but now docker is one of the hardest to install applications that I know of, and certainly isn't simply one executable file to be copied onto the system.

Managing resource files in fat binaries is really problematic.

I've never had trouble installing Docker anywhere, whether from package managers or installers. Where have you, and what kind of trouble? If I might run into something similar down the road, better I should know about it now.

It used to be that docker could be installed literally by downloading the docker binary, then it was a single curl command. Now the documentation looks like this: https://www.docker.com/get-docker

You press "get docker community image". Then you find your distro. Go to "download from the docker store", discover that there is no dowload link https://store.docker.com/editions/community/docker-ce-server... then you click on the long form link to the docs. Which gets you here: https://docs.docker.com/engine/installation/linux/docker-ce/...

And then that is not simple at all.

So much for fat binaries making things easy. Good-ness grief.

Adding a package repository and installing some packages doesn't seem that hard, and the major distros - and at least some minor ones; I see mention of Mint there - are supported. I've never had to do more than that, and it hasn't seemed especially objectionable; I have to confess I'm still not seeing where the additional burden arises.

If you simply want the latest stable docker version, try:

  curl -o /tmp/get-docker.sh https://get.docker.com && bash /tmp/get-docker.sh

or even just

  curl https://get.docker.com | bash

You can also use this script to update to the latest version, if you previously used it to install.
