利用github的actions实现blog的cicd

参考: https://zellwk.com/blog/github-actions-deploy/

首先博客如果使用hexo搭建, 且借助hexo-deployer-git依赖进行远程上传的话, 则需要将repo设置为ssh方式, https方式是不支持的, 如下

deploy:
  type: git
  # Windows: https://github.com/wang-xiaowu/wang-xiaowu.github.io.git
  repo: git@github.com:wang-xiaowu/wang-xiaowu.github.io.git
  branch: master

当前样例为, 一个blog_source库(未公开)存储未编译md文档, 走cicd流程之后, 将编译好的资源利用hexo d的方式部署到另一个一个github源仓库(开源库)

首先配置ssh/private key

1	ssh-keygen -t rsa -b 4096 -C "943915349@qq.com" -f key

邮箱修改为本人邮箱

复制publickey内容到github源仓库(也就是hexo中远程推送repo的地址)

打开浏览器登录你的github，点击右上角带黄色的头像-->settings-->（personal settings中的）SSH and GPG keys-->new SSH key-->title自己取名，key中粘贴publickey-->Add SSH key-->成功！

在blog_source库中进行操作, 创建一个名为SSH_PRIVATE_KEY的secret,将privatekey内容复制进去,如下

创建一个名为SSH_HOST的secret, 将`github.com`写入进去. 我们会在之后的操作中将它copy到`~/.ssh/known_hosts`中

创建actions

我们点击configure后, 进入编辑, 编辑内容如下

# This workflow will do a clean installation of node dependencies, cache/restore them, build the source code and run tests across different versions of node
