Why is the linux build so much bigger than the others?

[retrogradeorbit]

Not a bug, just a question I'm having a hard time trying to find the answer to.

Take the 5.4.1 built artifacts for example:

darwin: 61.3MB
windows: 59.1MB
linux 537 MB!!

It's almost ten times the size!!

However the fly artifact, they are all about the same size.

What is going on here?

I believe we package the linux binary with our base resource types (git, docker, etc...). These resources are based off of ubuntu docker images which are quite large. Non-linux workers do not run resources (checks, gets, puts) but only tasks. So their binaries will be a lot smaller.

cc @cirocosta you've been working on something for this right?

We actually package the alpine variants for the binary distribution since otherwise it'd be even bigger.

We're planning to extract them out: concourse/rfcs#30
