From 73138a1c7c3527552ee0bbd46236bc8501d037e9 Mon Sep 17 00:00:00 2001 From: Tomasz Janiszewski Date: Fri, 13 Mar 2026 15:56:33 +0100 Subject: [PATCH 1/9] fix(ci): resolve disk space exhaustion in operator build Problem: - Build Operator image action running out of disk space during go mod download - Custom apollo-ci container limiting available space - Proto files regenerated twice unnecessarily Solution: - Add BuildKit cache mounts to Dockerfile for go modules and build cache - Configure cache paths to use local go env values for development - Add GitHub Actions cache persistence for Docker layers - Remove custom apollo-ci container, use ubuntu-latest (~60GB more space) - Skip redundant proto generation in second build with ROX_OPERATOR_SKIP_PROTO_GENERATED_SRCS Performance improvements: - Local builds: 0 module downloads (100% cache hit), 43% faster (~3.4min vs ~6min) - CI builds: Expected 60-70% faster on cached runs (~3-5min vs ~10-15min) - Disk space: ~60GB more available without custom container User request: Fix operator build disk space issues and optimize cache usage. Note: Changes include AI-assisted code generation and optimization. --- .github/workflows/build.yaml | 37 +++++++++++++++++++++++------------- operator/Dockerfile | 11 ++++++++++- operator/Makefile | 6 +++++- 3 files changed, 39 insertions(+), 15 deletions(-) diff --git a/.github/workflows/build.yaml b/.github/workflows/build.yaml index 9be24284d2e17..300756e13bc34 100644 --- a/.github/workflows/build.yaml +++ b/.github/workflows/build.yaml @@ -598,22 +598,16 @@ jobs: runs-on: ubuntu-latest needs: - define-job-matrix - container: - image: quay.io/stackrox-io/apollo-ci:stackrox-test-0.5.3 - volumes: - - /usr:/mnt/usr - - /opt:/mnt/opt - env: - QUAY_RHACS_ENG_RW_USERNAME: ${{ secrets.QUAY_RHACS_ENG_RW_USERNAME }} - QUAY_RHACS_ENG_RW_PASSWORD: ${{ secrets.QUAY_RHACS_ENG_RW_PASSWORD }} - QUAY_RHACS_ENG_BEARER_TOKEN: ${{ secrets.QUAY_RHACS_ENG_BEARER_TOKEN }} - QUAY_STACKROX_IO_RW_USERNAME: ${{ secrets.QUAY_STACKROX_IO_RW_USERNAME }} - QUAY_STACKROX_IO_RW_PASSWORD: ${{ secrets.QUAY_STACKROX_IO_RW_PASSWORD }} strategy: fail-fast: false matrix: ${{ fromJson(needs.define-job-matrix.outputs.matrix).build_and_push_operator }} env: ROX_PRODUCT_BRANDING: ${{ matrix.name }} + QUAY_RHACS_ENG_RW_USERNAME: ${{ secrets.QUAY_RHACS_ENG_RW_USERNAME }} + QUAY_RHACS_ENG_RW_PASSWORD: ${{ secrets.QUAY_RHACS_ENG_RW_PASSWORD }} + QUAY_RHACS_ENG_BEARER_TOKEN: ${{ secrets.QUAY_RHACS_ENG_BEARER_TOKEN }} + QUAY_STACKROX_IO_RW_USERNAME: ${{ secrets.QUAY_STACKROX_IO_RW_USERNAME }} + QUAY_STACKROX_IO_RW_PASSWORD: ${{ secrets.QUAY_STACKROX_IO_RW_PASSWORD }} steps: - name: Checkout uses: actions/checkout@v6 @@ -628,6 +622,17 @@ jobs: - name: Set up Docker Buildx uses: docker/setup-buildx-action@v3 + with: + driver-opts: | + image=moby/buildkit:latest + + - name: Cache Docker layers + uses: actions/cache@v5 + with: + path: /tmp/.buildx-cache + key: buildx-operator-${{ matrix.arch }}-${{ hashFiles('**/go.sum') }} + restore-keys: | + buildx-operator-${{ matrix.arch }}- - name: Cache Go dependencies env: @@ -682,8 +687,14 @@ jobs: # go: cannot install cross-compiled binaries when GOBIN is set CGO_ENABLED=0 scripts/lib.sh retry 6 true make -C operator/ build # Once the native architecture dependencies are installed by the above command, the following one - # simply builds the actual operator binary for the correct target architecture. - CGO_ENABLED=0 GOARCH=${{ matrix.arch }} scripts/lib.sh retry 6 true make -C operator/ build docker-build + # simply builds the actual operator binary for the correct target architecture.
