docker容器出现status: restarting而不是status: up的话说明是镜像有问题
可以通过

1. docker logs <容器id>
   来查看错误日志
2. 排查修改源码之后可以通过docker-compose up -d --force-recreate --build来重新打包镜像

centos安装docker全家桶

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

之前装过要重装需要卸载旧版本

sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

换源

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://l7c7zlff.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

连接容器

docker exec -it <container name> /bin/sh
