Julia CI with Buildkite

Name: julia-ci-buildkite
Rating: 76
Author: Krastanov

Configure continuous integration for Julia packages using Buildkite.

Buildkite is useful for:

•GPU testing (CUDA, ROCm, OpenCL)
•Specialized hardware queues
•Long-running tests that exceed GitHub Actions limits
•Private/on-premise runners

Basic Pipeline

.buildkite/pipeline.yml

yaml

env:
  CODECOV_TOKEN: your-codecov-token
  JULIA_NUM_THREADS: auto,auto
  PYTHON: ""

steps:
  - label: "MyPackage Tests"
    plugins:
      - JuliaCI/julia#v1:
          version: "1"
      - JuliaCI/julia-test#v1: ~
      - JuliaCI/julia-coverage#v1:
          codecov: true
          dirs: './src,./ext'

Matrix Builds

yaml

steps:
  - label: "Tests - {{matrix.LABEL}}"
    plugins:
      - JuliaCI/julia#v1:
          version: "1"
      - JuliaCI/julia-test#v1: ~
    env:
      JET_TEST: "{{matrix.JET_TEST}}"
    agents:
      queue: "{{matrix.QUEUE}}"
    matrix:
      setup:
        LABEL: ["base tests"]
        QUEUE: ["default"]
        JET_TEST: ["false"]
      adjustments:
        - with:
            LABEL: "JET"
            QUEUE: default
            JET_TEST: true

Agent Queues

Route jobs to specific hardware:

Queue	Purpose
`default`	Standard x86_64 runners
`cuda`	NVIDIA GPU runners
`rocm`	AMD GPU runners
`arm64`	ARM runners

yaml

agents:
  queue: "{{matrix.QUEUE}}"

Available Plugins

Plugin	Purpose
`JuliaCI/julia#v1`	Install Julia
`JuliaCI/julia-test#v1`	Run package tests
`JuliaCI/julia-coverage#v1`	Generate/upload coverage
`QuantumSavory/julia-xvfb#v1`	Virtual framebuffer for graphics
