一. 離線安裝

1. 下載docker

  wget https://download.docker.com/linux/static/stable/x86_64/docker-27.1.2.tgz wget  https://download.docker.com/linux/static/stable/aarch64/docker-27.1.2.tgz

?

2. 安裝

tar -zxvf docker-27.1.2.tgzsudo cp docker/* /usr/bin/

將docker注冊成系統服務;

vim /etc/systemd/system/docker.service[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target[Service]
Type=notify
ExecStart=/usr/bin/dockerd
ExecReload=/bin/kill -s HUP $MAINPID
LimitNOFILE=infinity
LimitNPROC=infinity
TimeoutStartSec=0
Delegate=yes
KillMode=process
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s[Install]
WantedBy=multi-user.target

### 增加可執行權限
chmod +x /etc/systemd/system/docker.service
systemctl daemon-reload ### 設置開機自啟動
systemctl enable docker.service### 啟動 docker
systemctl start docker### 測試 docker 是否啟動
docker --versiondocker run hello-world### 停止 docker
sudo systemctl stop docker

?

二. 相關命令

### 鏡像源
vim /etc/docker/daemon.json
# 例如
{"registry-mirrors": ["https://dockerproxy.com","https://hub-mirror.c.163.com","https://mirror.baidubce.com","https://ccr.ccs.tencentyun.com"]
}### 重新啟動服務
sudo systemctl daemon-reload
sudo systemctl restart docker### 查看配置
docker info

?

三. 配置docker-compose

cp docker-compose-linux-x86_64 /usr/bin/docker-compose
chmod +x /usr/bin/docker-compose
docker-compose --version

?
