laradock一些坑(长期维护)

一：build mysql报错:

• 解决方案1: 

如果是使用docker-deskstop软件, 去软件设置 > docker engine > json文件修改以下配置:

  "features": {
    "buildkit": false
  },

• 解决方案2:   

调试了两小时才发现，原来是找不到镜像，所以解决思路是先尝试用docker pull 或者docker run命令把mysql:8.0多镜像下载下来, 然后重新build mysql , 因为buid会先检查本机有没有mysql:8.0镜像，从而解决问题。

运行一下命令:

docker run --name=mysql8test -e MYSQL_ROOT_PASSWORD=root -d -p 3306:3306 mysql:8.0

docker ps
