一、目录中的三类内容¶
1.1 文件清单¶
install_docker.sh：在线安装脚本。install_docker_offline.sh：离线安装脚本。docker-28.0.4.tgz：离线二进制安装包。
1.2 在线与离线的拆分逻辑¶
- 在线脚本：适合能访问软件仓库的环境，优势是版本切换灵活。
- 离线脚本：适合封网环境，优势是可控、可复制、依赖少。
二、在线安装脚本整理¶
2.1 在线脚本的关键点¶
DOCKER_VERSION="28.0.4"
UBUNTU_DOCKER_VERSION="5:${DOCKER_VERSION}-1~ubuntu.${VERSION_ID}~${UBUNTU_CODENAME}"
DOCKER_URL="http://mirrors.ustc.edu.cn"
2.2 在线安装的核心流程¶
yum -y install docker-ce-$DOCKER_VERSION docker-ce-cli-$DOCKER_VERSION
apt update
apt -y install apt-transport-https ca-certificates curl software-properties-common
add-apt-repository -y "deb [arch=amd64] ${DOCKER_URL}/docker-ce/linux/ubuntu $(lsb_release -cs) stable"
apt -y install docker-ce=${UBUNTU_DOCKER_VERSION} docker-ce-cli=${UBUNTU_DOCKER_VERSION}
三、离线安装脚本整理¶
3.1 离线安装脚本的思路¶
tar xf docker-${DOCKER_VERSION}.tgz -C /usr/local/
cp /usr/local/docker/* /usr/local/bin/
cat > /lib/systemd/system/docker.service <<EOF
[Unit]
Description=Docker Application Container Engine
After=network-online.target firewalld.service
[Service]
ExecStart=/usr/local/bin/dockerd -H unix://var/run/docker.sock
Restart=on-failure
EOF
3.2 通用的 daemon.json 配置¶
cat > /etc/docker/daemon.json <<EOF
{
"registry-mirrors": [
"https://docker.m.daocloud.io",
"https://docker.1panel.live",
"https://docker.1ms.run"
],
"insecure-registries": ["harbor.example.com"],
"live-restore": true
}
EOF
四、完整脚本¶
