CentOS 7.x 安裝 Docker-ce

CentOS 7.0, CentOS 7.2:

cat > /etc/yum.repos.d/docker-main.repo << -‘EOF’
[docker-main-repo]
name=Docker main Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/7
enabled=1
gpgcheck=1
gpgkey=https://yum.dockerproject.org/gpg
-EOF

yum install docker-engine -y
systemctl start docker

CentOS 7.4:

yum install -y yum-utils

yum-config-manager –add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

yum install -y docker-ce

systemctl start docker

cat > /etc/docker/daemon.json << -‘EOF’
{
 “registry-mirrors”: [“https://registry.docker-cn.com”]
}
-EOF

systemctl restart docker

注意：這里的服務(wù)器系統(tǒng)時(shí)間需要設(shè)置為中國(guó)時(shí)區(qū)，時(shí)間不同可能會(huì)導(dǎo)致鏡像無法下載，很多人喜歡用虛擬機(jī)來做實(shí)驗(yàn)，最好把命令放到定時(shí)任務(wù)中。
