安裝docker-ce

下載二進位制docker

官方下載地址：https://download.docker.com/linux/static/stable/aarch64/

登入伺服器下載相應的軟體包

wget https://download.docker.com/linux/static/stable/aarch64/docker-20.10.9.tgz

解壓下載好的壓縮包

[root@ecs-arm-ky-001 ~]# tar -zxvf docker-20.10.9.tgz

移動解壓出來的二進位制檔案到/usr/bin目錄中

[root@ecs-arm-ky-001 ~]# mv docker/* /usr/bin/

測試docker

[root@ecs-arm-ky-001 ~]# dockerd

新增systemd

新增docker的systemd服務指令碼到  /usr/lib/systemd/system/

指令碼參考自 https://github.com/docker/docker-ce

# 使用這個才能啟動成功

過載systemd配置檔案

[root@ecs-arm-ky-001 ~]# systemctl daemon-reload

建立docker組

groupadd docker

如不建立 docker 組在通過 systemctl 啟動時會報錯如下

Dependency failed for Docker Application Container Engine.
Job docker.service/start failed with result 'dependency'.

啟動 docker 服務

[root@ecs-arm-ky-001 ~]# systemctl start docker
[root@ecs-arm-ky-001 ~]# systemctl enable docker
Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.service.

修改 docker 配置檔案並檢視安裝好的 docker 基本資訊，增加docker映象加速

mkdir -p /etc/docker/
cat > /etc/docker/daemon.json <<'EOF'
{
  "registry-mirrors": ["https://s7p0cq94.mirror.aliyuncs.com"]
}
EOF

重啟 docker 服務

systemctl restart docker

檢視 docker info

docker info
