CentOS 8 部署Docker

RHEL8開始，在原本docker-ce的安裝之前，還需要額外安裝containerd.io的依賴包

[zhuxiaoshuai@docker~]#  curl https://download.docker.com/linux/centos/docker-ce.repo -o /etc/yum.repos.d/docker-ce.repo #下載docker-ce最新的repo
[zhuxiaoshuai@docker~]#  yum install -y https://download.docker.com/linux/fedora/30/x86_64/stable/Packages/containerd.io-1.2.6-3.3.fc30.x86_64.rpm #安裝containerd.io依賴
[zhuxiaoshuai@docker~]#  yum install -y docker-ce #安裝docker-ce
[zhuxiaoshuai@docker~]# systemctl start docker && systemctl enable docker 

[zhuxiaoshuai@docker~]# docker pull centos
