離線裝docker
一、下載安裝包
docker安裝包下載：https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-18.09.8-3.el7.x86_64.rpm

依賴包下載：
containerd.io：https://download.docker.com/linux/centos/7/x86_64/stable/Packages/containerd.io-1.2.2-3.el7.x86_64.rpm

docker-ce-cli：https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-cli-18.09.8-3.el7.x86_64.rpm

container-selinux：http://mirror.centos.org/centos/7/extras/x86_64/Packages/container-selinux-2.107-3.el7.noarch.rpm

二、安裝

rpm -ivh docker-ce-cli-18.09.8-3.el7.x86_64.rpm

rpm -ivh container-selinux-2.107-3.el7.noarch.rpm

rpm -ivh containerd.io-1.2.2-3.el7.x86_64.rpm

rpm -ivh docker-ce-18.09.8-3.el7.x86_64.rpm

注意：當提示類似policycoreutils-python is needed by container-selinux提示，可以這樣解決：
1.主動安裝依賴
python install policycoreutils-python
2.強制安裝，忽略相關依賴
rpm -ivh ***.rmp --nodeps --force

三、啟動docker

啟動

systemctl start docker

開機啟動docker

systemctl enable docker

檢視狀態

systemctl status docker
