I’m trying to find a thing, and I’m not turning up anything in my web searches so I figure I’d ask the cool people for help.
I’ve got several projects, tracked in Git, that rely on having a set of command line tools installed to work on locally - as an example, one requires Helm, Helmfile, sops, several Helm plugins, Pluto, Kubeval and the Kubernetes CLI. Because I don’t hate future me, I want to ensure that I’m installing specific versions of these tools rather than just grabbing whatever happens to be the latest version. I also want to ensure that my CI runner grabs the same versions, so I can be reasonably sure that what I’ve tried locally will actually work when I go to deploy it.
My current solution to this is a big ol’ Bash script, which works, but is kind of a pain to maintain. What I’m trying to find is a tool where I:
Can write a definition, ideally somewhere shared between projects, of what it means to “install tool X”
Include a file in my project that lists the tools and versions I want
Run the tool on my machine and let it go grab the platform- and architecture- specific binaries from wherever, and install them somewhere that I can add to my $PATH for this specific project
Run the tool in CI and do the same - if it can cache stuff then awesome
Linux support is a must, other platforms would be nice as well.
Basically I’m looking for Pythons’ pip + virtualenv workflow, but for prebuilt tools like helm, terraform, sops, etc. Anyone know of anything? I’ve looked at homebrew (seems to want to install system-wide), and VSCode dev containers (doesn’t solve the CI need, and I’d still need to solve installing the tools myself)
Dev containers is a Docker container under the hood, it’s just some tooling to make it slightly easier to set up - same objections, if I’m using Docker, I’m still stuck with a gross script, just that it’s running inside the container rather than directly on my machine
Now install tools that are only available as github released binaries. And ensure that hashes match for that. Maybe install a tool that needs to be compiled.

I have no knowledge in this area, but this really sounds like containers territory (Docker, not VSCode) ?

What do you mean? I containerize my tools, and write a docker file to install everything. The dockerfile is just something like:
FROM ubuntu:22.04
RUN apt-get update &&
apt-get install -y helm pluto kubeval etc
How is that gross?

It’s news to me that we’re not all just abusing Docker for this. I’ll have to look into some of these mentioned tools.
