CentOS8.1安装docker记录


卸载 CentOS 8.1 自带的podman
[root@centos8 ~]# rpm -qa | grep -i podman
podman-manpages-1.6.4-4.module_el8.1.0+298+41f9343a.noarch
podman-1.6.4-4.module_el8.1.0+298+41f9343a.x86_64
[root@centos8 ~]# dnf remove podman podman-manpages



[root@centos8 ~]# dnf config-manager --add-repo=
[root@centos8 ~]# dnf repolist -v
docker-ce

默认软件源中的 containerd.io 版本较低，无法达到安装 docker-ce 的要求。

containerd.io > 1.2.0-3.el7

[root@centos8 ~]# wget
[root@centos8 ~]# dnf -y install containerd.io-1.2.13-3.1.el7.x86_64.rpm
[root@centos8 ~]#
[root@centos8 ~]# dnf list docker-ce
