hmarr/debug-action

  • docker action
  • 打印环境变量和evnet payload

仓库分析

  • license/readme是常规操作
  • 是一个docker action
  • 元数据并不是通过action.yml展示的，而是写在Dockerfile中
FROM alpine

LABEL "repository"="http://github.com/hmarr/debug-action"
LABEL "homepage"="http://github.com/hmarr/debug-action"
LABEL "maintainer"="Harry Marr <[email protected]>"

LABEL "com.github.actions.name"="Debug Action"
LABEL "com.github.actions.description"="Log the action's environment variables and event payload"
LABEL "com.github.actions.icon"="code"
LABEL "com.github.actions.color"="yellow"

RUN apk --no-cache add jq

ADD entrypoint.sh /entrypoint.sh
ENTRYPOINT ["/entrypoint.sh"]

action 分析

  • Dockderfile就配置了一个jq工具(格式化json的工具)
#!/bin/sh

set -e

echo
echo "-- Environment variables ----------------------------------------------"
env
echo "-----------------------------------------------------------------------"

echo
echo "-- Event JSON ---------------------------------------------------------"
cat "$GITHUB_EVENT_PATH" | jq -M .
echo "-----------------------------------------------------------------------"
echo
  • 可以看出，打印了环境变量和事件信息

使用
