centos8 安裝docker

sudo yum install -y yum-utils

sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

sudo yum install docker-ce docker-ce-cli containerd.io

可能會報錯 containerd.io >= 1.2.2-3

解決

wget https://download.docker.com/linux/centos/7/x86_64/stable/Packages/containerd.io-1.2.13-3.1.el7.x86_64.rpm 

yum -y install ./containerd.io-1.2.13-3.1.el7.x86_64.rpm

此時再次運行安裝docker可能還會報錯：

file /usr/share/man/man1/docker-attach.1.gz from install of docker-ce-cli-1:19.03.6-3.el7.x86_64 conflicts with file from package podman-manpages-1.4.2-5.module_el8.1.0+237+63e26edc.noarch

解決

先查看是否安裝 Podman

rpm -q podman
podman-1.4.2-5.module_el8.1.0+237+63e26edc.x86_64

刪除Podman

dnf remove podman

 

解決後，再次執行

sudo yum install docker-ce docker-ce-cli containerd.io

成功後，啓動docker

sudo systemctl start docker
