1紧索、通過 RPM 安裝 docker 17.03.0 版本并且配置 docker 阿里加速
# rpm...選擇centos7 安裝
#————————————————————————————————————————————————————————————————————————————
# 方法一：
# 添加倉庫：
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# 安裝：
yum install -y --setopt=obsoletes=0 \
docker-ce-17.03.1.ce-1.el7.centos docker-ce-selinux-17.03.1.ce-1.el7.centos
systemctl enable --now docker.service
docker version
#----------------------------------------------------------------------------
# 方法二：
# 依賴包 docker-ce-selinux
yum -y install https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/stable/Packages/docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch.rpm
# 安裝包 docker-ce
yum -y install https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/stable/Packages/docker-ce-17.03.0.ce-1.el7.centos.x86_64.rpm
'也可以直接一步安裝：
yum -y install https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/stable/Packages/docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch.rpm https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/stable/Packages/docker-ce-17.03.0.ce-1.el7.centos.x86_64.rpm
systemctl enable --now docker.service
docker version
2咖气、通過 docker 安裝一個(gè) LAMP 架構(gòu)
思路：將AMP分別運(yùn)行為3個(gè)容器
1 = ubuntu安裝docker
# step 1: 更新并安裝必要的系統(tǒng)工具
apt update
apt -y install apt-transport-https ca-certificates curl software-properties-common
# step 2: 安裝GPG證書
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
# Step 3: 將阿里源添加至倉庫
add-apt-repository "deb [arch=amd64] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"
# Step 4: 安裝Docker-CE
apt -y install docker-ce
# Step 5: 檢查

# 當(dāng)容器退出時(shí)自動(dòng)移除容器
docker run --rm xxx
'注意： 不能與選項(xiàng) -d 共用
4雏掠、 docker run 命令通過什么參數(shù)能夠?qū)崿F(xiàn)容器隨著 docker 服務(wù)的啟動(dòng)而自動(dòng)啟動(dòng)
docker run --restart=always xxx
# --restart=always：無論容器的退出狀態(tài)如何斩祭，始終重啟容器
