CI Failure Report

Workflow: feat: multi-platform Docker builds (amd64 + arm64 + arm/v7)
Commit: 467c7a73f8
Run: https://git.brads.house/dungeonchurch/5e-tools-mcp/actions/runs/48
Status: failure
Attempts: 2/3

Triage Analysis

Root Cause: Docker buildx plugin not available in the Debian docker.io package.

Evidence:

Error: unknown flag: --name
Failure in "Create buildx builder" step: docker buildx create --name multiarch --use
Debian bookworm docker.io package (20.10.24) includes buildx as CLI plugin, but it was not accessible/enabled
Binfmt setup succeeded (tonistiigi/binfmt installed arm64, arm support)
Buildx command was not recognized, causing Docker to treat arguments incorrectly

Context:

Workflow installs docker.io via apt-get from Debian repositories
Multi-platform build requires buildx for cross-platform image building
The workflow uses --privileged container mode and QEMU for ARM emulation

Resolution

Status: Fix already committed and in progress

Fix commit: fix(ci): install Docker CE + buildx from official repo (e6e036b...)
Fix run #3432/3433: Currently testing
Resolution: Install Docker CE and buildx from official Docker repository instead of Debian package

Recommended changes:

# Replace:
- name: Install Docker CLI
  run: apt-get update && apt-get install -y --no-install-recommends docker.io

# With:
- name: Install Docker CE + buildx
  run: |
    apt-get update
    apt-get install -y ca-certificates curl
    install -m 0755 -d /etc/apt/keyrings
    curl -fsSL https://download.docker.com/linux/debian/gpg -o /etc/apt/keyrings/docker.asc
    chmod a+r /etc/apt/keyrings/docker.asc
    echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/debian $(. /etc/os-release && echo "$VERSION_CODENAME") stable" > /etc/apt/sources.list.d/docker.list
    apt-get update
    apt-get install -y docker-ce docker-ce-cli docker-buildx-plugin docker-compose-plugin

Pattern

Added to MEMORY.md: "Docker buildx Plugin Missing in Debian Package"

Debian docker.io package may not have buildx plugin properly accessible
Use official Docker repository for CE packages with full buildx support
Detection: docker buildx commands fail with "unknown flag" errors
