Using Hashicorp Waypoint runner for Kubernetes is pretty straight forward... but sometimes runs into permissions errors.

Specifically jobs.batch is forbidden: User "system:serviceaccount:waypoint:waypoint-runner" cannot create resource "jobs" in API

You need to

• create a role with access to the jobs.batch api
• bind it to the service account

You can do this as follows

let
  mach-nix = import (builtins.fetchGit {
    url = "https://github.com/DavHau/mach-nix";
    ref = "refs/tags/3.4.0";
  }) {
    python = "python39";
    pypiData = builtins.fetchTarball "https://github.com/DavHau/pypi-deps-db/tarball/master";

Generate code for configuration.nix with packages that you need installed

Using nix-template for ease of use

nix-shell -p nix-template

# add any package you want with the `-u` flag
nix-template python -u https://pypi.org/project/libagent/ --stdout

0xperp

# should include all of the packages that you need and produce a binary
nix-shell -p cargo libiconv openssl pkgconfig --run "cargo build --release"
