阿里云服务器docker与docker copmpose安装及问题解决

docker安装
yum -y install docker

出现
Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.
Error: missing command ‘podman COMMAND’
Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.
podman version 3.0.2-dev
默认安装带podman所以先卸载
yum remove docker

阿里云服务器正确的安装方式
curl https://download.docker.com/linux/centos/docker-ce.repo -o /etc/yum.repos.d/docker-ce.repo
yum install docker-ce -y
这时候docker -v验证一下即可

docker compose安装
国外的镜像下载不下来于是乎换了国内镜像下载
curl -L https://get.daocloud.io/docker/compose/releases/download/1.20.1/docker-compose-uname -s-uname -m > /usr/local/bin/docker-compose

成功安装
