1# This file defines an action that builds the various Docker images used to run2# libc++ CI whenever modifications to those Docker files are pushed to `main`.3#4# The images are pushed to the LLVM package registry at https://github.com/orgs/llvm/packages5# and tagged appropriately. The selection of which Docker image version is used by the libc++6# CI nodes at any given point is controlled from the workflow files themselves.7 8name: Build Docker images for libc++ CI9 10permissions:11 contents: read12 13on:14 push:15 branches:16 - main17 paths:18 - 'libcxx/utils/ci/docker/**'19 - '.github/workflows/libcxx-build-containers.yml'20 pull_request:21 paths:22 - 'libcxx/utils/ci/docker/**'23 - '.github/workflows/libcxx-build-containers.yml'24 25jobs:26 build-and-push:27 runs-on: ubuntu-24.0428 if: github.repository_owner == 'llvm'29 permissions:30 packages: write31 32 steps:33 - uses: actions/checkout@1af3b93b6815bc44a9784bd300feb67ff0d1eeb3 # v6.0.034 35 # The default Docker storage location for GitHub Actions doesn't have36 # enough disk space, so change it to /mnt, which has more disk space.37 - name: Change Docker storage location38 run: |39 sudo mkdir /mnt/docker40 echo '{ "data-root": "/mnt/docker" }' | sudo tee /etc/docker/daemon.json41 sudo systemctl restart docker42 43 - name: Build the base image44 run: docker compose --file libcxx/utils/ci/docker/docker-compose.yml build libcxx-linux-builder-base45 env:46 TAG: ${{ github.sha }}47 48 - name: Build the Linux Github Actions image49 run: docker compose --file libcxx/utils/ci/docker/docker-compose.yml build libcxx-linux-builder50 env:51 TAG: ${{ github.sha }}52 53 - name: Build the Android builder image54 run: docker compose --file libcxx/utils/ci/docker/docker-compose.yml build libcxx-android-builder55 env:56 TAG: ${{ github.sha }}57 58 - name: Log in to GitHub Container Registry59 uses: docker/login-action@5e57cd118135c172c3672efd75eb46360885c0ef # v3.6.060 with:61 registry: ghcr.io62 username: ${{ github.actor }}63 password: ${{ secrets.GITHUB_TOKEN }}64 65 - name: Push the images66 if: github.event_name == 'push'67 run: docker compose --file libcxx/utils/ci/docker/docker-compose.yml push libcxx-linux-builder-base libcxx-linux-builder libcxx-android-builder68 env:69 TAG: ${{ github.sha }}70 71 # We create tarballs with the images and upload them as artifacts, since that's useful for testing72 # the images when making changes.73 - name: Create image tarballs74 run: |75 docker image save ghcr.io/llvm/libcxx-linux-builder-base:${{ github.sha }} | gzip > libcxx-linux-builder-base.tar.gz76 docker image save ghcr.io/llvm/libcxx-linux-builder:${{ github.sha }} | gzip > libcxx-linux-builder.tar.gz77 docker image save ghcr.io/llvm/libcxx-android-builder:${{ github.sha }} | gzip > libcxx-android-builder.tar.gz78 - uses: actions/upload-artifact@330a01c490aca151604b8cf639adc76d48f6c5d4 # v5.0.079 with:80 name: libcxx-docker-images81 path: |82 libcxx-linux-builder-base.tar.gz83 libcxx-linux-builder.tar.gz84 libcxx-android-builder.tar.gz85
