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" location = "docker.io" insecure = false [[registry.mirror]] location = "docker.m.daocloud.io" insecure = true [[registry.mirror]] location = "docker.1panel.live" insecure = true [[registry.mirror]] location = "hub.rat.dev" insecure = true [[registry.mirror]] location = "dockercf.jsdelivr.fyi" insecure = true [[registry.mirror]] location = "docker.rainbond.cc" insecure = true [[registry.mirror]] location = "dhub.kubesre.xyz" insecure = true [[registry.mirror]] location = "reg.example.com" # 自建 Harbor 镜像仓库 insecure = true
3、Podman使用docker命令
dnf -y install podman-docker
4、启动服务
systemctl enable --now podman
5、命令补全
dnf install bash-completion -y
6、Podman命令
