act本地运行GithubAction记录

最近想本地运行个 github action 打包个 libmpv 出来，折腾一顿遇到不少小问题，记录一下咋搞
act 添加参数-v运行时输出更详细的日志：

act -v -W .github/workflows/build.yaml

问题和解决

Job failed Error: unsupported object type
- 拉取gradle-actions时报的错：

在workflow/xxx.yaml 里写的是正常的，查了一下act的issue，应该是 github 在线运行就正常，用act本地运行就有问题，后面的版本号v4改成一个具体版本就可以了，比如v4.4.4：

yaml

      - name: Setup Gradle
        # uses: gradle/actions/setup-gradle@v4  # 原本的
        uses: gradle/actions/setup-gradle@v4.4.4 # 改为具体版本号

skipping post step for 'Checkout repository': no action model available
- 出现这句的时候很多时候是前面的步骤就已经报错了，得把日志往前翻，找到真正的报错，然后再分析：

[Build libmpv-android/Build]   ❌  Failure - Main Bundle (default) [4m40.674318163s]

挂了VPN后仍然有很多网络错误：

- 如果vpn运行在windows，使用的WSL, 需要export将wsl的流量代理到windows的vpn上：

export http_proxy=http:win_ip:vpn_port
export https_proxy=http:win_ip:vpn_port

- 修改docker的代理配置，vim ：

sudo mkdir -p /etc/systemd/system/docker.service.d
vi /etc/systemd/system/docker.service.d/http-proxy.conf

- 添加内容，跟正常 export 环境变量一样：

conf

[Service]
Environment="HTTP_PROXY=http://user:passwd@ip:port"
Environment="HTTPS_PROXY=http://user:passwd@ip:port"
Environment="NO_PROXY=localhost,127.0.0.1"

运行失败调试和复用容器
- 默认情况下, act 每次运行都会把docker容器删了重新建立一个新的，可以加上 --reuse 复用已有的容器，此时我们就可以docker进入容器内打补丁，少了什么库、环境变量、配置代理都可以进入后手动操作好，然后用act跑一下：

# 查看docker容器
docker ps 

(base) root@ubuntu22:~/.cache/act/gradle-actions-setup-gradle@v5# docker ps
CONTAINER ID   IMAGE                           COMMAND               CREATED          STATUS          PORTS     NAMES
350213cdf9b8   catthehacker/ubuntu:act-22.04   "tail -f /dev/null"   37 minutes ago   Up 37 minutes             act-Build-libmpv-android-Build-a6637138a4eba25d208dc9b2305b13f191ae0fd2e7e9c29b24e55313c0d52ac4

进入容器：

docker exec --it {容器id，比如上面输出的350213cdf9b8} /bin/bash

平常装的容器是精简的，可能vim啥的都没有，直接apt安装就可以了
进去后按照act运行时的日志报错去手动操作后，在容器外主机再次运行act，加上--reuse即可：

act -v -W .github/workflows/build.yaml --reuse

Error: invalid reference format

github action运行正常，但act运行就马上报错invalid reference format，查了一下问题多种多样，我这里是因为 yaml 或命令行指定了 container 格式问题：

yaml

jobs:
  build_llvm:
    name: Building LLVM and Clang
    runs-on: ubuntu-latest
    container:
      # image: docker://ghcr.io/shinchiro/archlinux:latest # 提示错误
      image: ghcr.io/shinchiro/archlinux:latest

命令行运行act时的参数同理：

act -v -W .github/workflows/work.yaml -P ubuntu-latest=ghcr.io/shinchiro/archlinux:latest
# act -v -W .github/workflows/work.yaml -P ubuntu-latest=docker://ghcr.io/shinchiro/archlinux:latest 提示错误

# 使用帮助其实有提示格式：
act -h

  -P, --platform stringArray                              custom image to use per platform (e.g. -P ubuntu-18.04=nektos/act-environments-ubuntu:18.04)
