龙芯安装Docker

article 2025/1/20 11:55:05

本文章使用龙芯3A6000处理器，Loongnix操作系统。
官方文档：

http://docs.loongnix.cn/loongnix/cloud/docker/manual.html

1 安装Docker

1.1 卸载docker

sudo apt remove docker

1.2 更新

sudo apt update

1.3 安装Docker

sudo apt install docker-ce docker-ce-cli containerd.io

1.4 配置镜像仓库

如果安装出现以下错误：

Process: 5566 ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock (code=exited, status=1/FAILURE)
 Main PID: 5566 (code=exited, status=1/FAILURE)
dpkg: 处理软件包 docker-ce (--configure)时出错：
 已安装 docker-ce 软件包 post-installation 脚本 子进程返回错误状态 1
dpkg: 依赖关系问题使得 docker-ce-rootless-extras 的配置工作不能继续：
 docker-ce-rootless-extras 依赖于 docker-ce；然而：
  软件包 docker-ce 尚未配置。

dpkg: 处理软件包 docker-ce-rootless-extras (--configure)时出错：
 依赖关系问题 - 仍未被配置
正在处理用于 systemd (241-7.lnd.11) 的触发器 ...
在处理时有错误发生：
 docker-ce
 docker-ce-rootless-extras
E: Sub-process /usr/bin/dpkg returned an error code (1)

则需要配置龙芯容器镜像仓库。
在/etc/docker/daemon.json 中追加以下内容，如果文件不存在请手动创建。

{
    "registry-mirrors": ["https://cr.loongnix.cn"]
}

1.5 重启docker

systemctl daemon-reload
systemctl restart docker

1.6 验证docker

1、获取docker版本

sudo docker version

显示如下：

Client:
 Version:           20.10.3
 API version:       1.41
 Go version:        go1.15.6
 Git commit:        
 Built:             Wed Mar 23 10:35:26 2022
 OS/Arch:           linux/loong64
 Context:           default
 Experimental:      true

Server:
 Engine:
  Version:          20.10.3
  API version:      1.41 (minimum version 1.12)
  Go version:       go1.15.6
  Git commit:       
  Built:            
  OS/Arch:          linux/loong64
  Experimental:     false
 containerd:
  Version:          1.4.3-1-g6fbe2f9
  GitCommit:        6fbe2f9a8e085ffeb72c00027c4f9**********
 runc:
  Version:          1.0.0-rc93+dev
  GitCommit:        
 docker-init:
  Version:          0.19.0
  GitCommit:

2、docker运行：

sudo docker run hello-world

显示如下：

Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world

Digest: sha256:645c181ed190871e4029bf059242e68261e106096bd08c0d11635449e1b88ff6

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
