Is there a way to embed or cache this in our CI Agent AMIs? We find that GitHub is rather unreliable. We see issues conservatively once a quarter and it disrupts CI. > Failed to fetch https://github.com/pantsbuild/pants/releases/download/release_2.28.0/pants.2.28.0-cp311-linux_x86_64.pex: [28] Timeout was reached (Failed to connect to github.com port 443 after 129444 ms: Couldn't connect to server) > Wasn't able to fetch the Pants PEX at https://github.com/pantsbuild/pants/releases/download/release_2.28.0/pants.2.28.0-cp311-linux_x86_64.pex. > Check to see if the URL is reachable. > > Exception: > Command '['/var/lib/buildkite-agent/.cache/nce/22652cf60b12e7a187ea0cf21d7bc9d8234bbb630fa94ca6f9c28655bd6a81fb/ptex-linux-x86_64', 'https://github.com/pantsbuild/pants/releases/download/release_2.28.0/pants.2.28.0-cp311-linux_x86_64.pex']' returned non-zero exit status 1. > Error: Failed to establish atomic directory /var/lib/buildkite-agent/.cache/nce/5c54a0c25255df2afb0525da856d49eb81b48cff0e32a9c868f77a296af24319/locks/install-c0ce0c6f977d6f5d0786222a4e158390b5b503257ea667345b3e995f3e2d738f.

Yes. In your AMI build script, download and install the Pants launcher binary. Then create a trivial Pants project with just a

pants.toml

set to the version of Pants you want (and the backend packages) to cache in the AMI. Then run

pants --version

and as a side effect that Pants version will be downloaded and its venv built in the AMI image.

We rebuild our CI agent AMI daily anyway because we have a large monorepo that we embed so this works great for us.

also if I rewrote this script now, I would avoid the

get-pants.sh

script and just download the scie-pants launcher directly from https://github.com/pantsbuild/scie-pants and check its expected sha256 hash.

@fast-nail-55400 this worked great. Thanks!
