Earthly工具尝试
最近发现一个比较有意思的镜像构建工具Earthly,文档地址
根据Earthly工具的介绍,它相当于Dockerfile+MAkefile+Bash
简单部署
根据官网文档简单试用一下：
因为各种原因，个人选择在docker:dind的容器环境中尝试使用。
启动docker:dind容器：
1
| docker run -d --privileged docker:dind
|
在容器中：
1
2
| wget https://github.com/earthly/earthly/releases/download/v0.5.19/earthly-linux-amd64 -O /usr/local/bin/earthly && chmod +x /usr/local/bin/earthly
#安装earthly

Earthly + Gitlab-CI简单实践
备注：此处仅做演示,故仅采用docker:dind容器来进行CI,仓库仍采用上面的python演示仓库
