1、安装Podman
dnf -y install podman
2、配置镜像加速和私有镜像仓库
# vim /etc/containers/registries.conf unqualified-search-registries = ["docker.io"] [[registry]] prefix = "docker.io" insecure = false blocked = false location = "docker.io" [[registry]] location="reg.example.com" insecure=true [[registry.mirror]] location = "hub-mirror.c.163.com" insecure = true [[registry.mirror]] location = "docker.mirrors.ustc.edu.cn" insecure = true [[registry.mirror]] location = "docker.nju.edu.cn" insecure = true short-name-mode = "enforcing"
3、Podman使用docker命令
dnf -y install podman-docker
4、命令补全
dnf install bash-completion -y
5、Podman命令
