華為鯤鵬麒麟安裝docker

安裝 Docker-ce

下載二進位制docker

官網下載地址：https://download.docker.com/linux/static/stable/aarch64/

解壓下載好的壓縮包

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

mv docker/* /usr/bin/

測試啟動

dockerd

新增 systemd

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

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

根據 docker.service 中 Unit.After 需求新增 docker.socket 指令碼至 /usr/lib/systemd/system/

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

cat > /usr/lib/systemd/system/docker.socket <<'EOF'
[Unit]
Description=Docker Socket for the API

如果缺少該檔案，啟動 docker 時會報如下錯誤：

systemctl start docker

過載 systemd 配置檔案

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

systemctl start docker
systemctl enable docker

修改 docker 配置檔案並檢視安裝好的 docker 基本資訊

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

重啟 docker 服務

systemctl restart docker

檢視 docker info
