GitHub CI action to build packages via SDK using official OpenWrt SDK Docker containers. This is primary used to test build OpenWrt repositories but can also be used for downstream projects maintaining their own package repositories.

The following YAML code can be used to build all packages of a repository and store created ipk files as artifacts.

name: Test Build

on:
  pull_request:
    branches:
      - main

jobs:
  build:
    name: ${{ matrix.arch }} build
    runs-on: ubuntu-latest
    strategy:
      matrix:
        arch:
          - x86_64
          - mips_24kc

    steps:
      - uses: actions/checkout@v2
        with:
          fetch-depth: 0

      - name: Build
        uses: openwrt/gh-action-sdk@main
        env:
          ARCH: ${{ matrix.arch }}

      - name: Store packages
        uses: actions/upload-artifact@v2
        with:
          name: ${{ matrix.arch}}-packages
          path: bin/packages/${{ matrix.arch }}/packages/*.ipk

The action reads a few env variables:

• ARCH determines the used OpenWrt SDK Docker container. E.g. x86_64 or x86_64-22.03.2.
• ARTIFACTS_DIR determines where built packages and build logs are saved. Defaults to the default working directory (GITHUB_WORKSPACE).
• DL_DIR determines where download source code packages are saved. Defaults to the default working directory (GITHUB_WORKSPACE).
• BUILD_LOG stores build logs in ./logs.
• CONTAINER can set other SDK containers than openwrt/sdk.
• EXTRA_FEEDS are added to the feeds.conf, where | are replaced by white spaces.
• FEED_DIR used in the created feeds.conf for the current repo. Defaults to the default working directory (GITHUB_WORKSPACE).
• FEEDNAME used in the created feeds.conf for the current repo. Defaults to action.
• IGNORE_ERRORS can ignore failing packages builds.
• INDEX makes the action build the package index. Default is 0. Set to 1 to enable.
• KEY_BUILD can be a private Signify/usign key to sign the packages feed.
• NO_DEFAULT_FEEDS disable adding the default SDK feeds
• NO_REPO_FEEDS disable adding the default working directory as feeds
• NO_REFRESH_CHECK disable check if patches need a refresh.
• NO_SHFMT_CHECK disable check if init files are formated
• PACKAGES (Optional) specify the list of packages (space separated) to be built
• V changes the build verbosity level.
