龙芯安装Docker

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-cedocker-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:           20.10.3API version:       1.41Go version:        go1.15.6Git commit:        Built:             Wed Mar 23 10:35:26 2022OS/Arch:           linux/loong64Context:           defaultExperimental:      trueServer:Engine:Version:          20.10.3API version:      1.41 (minimum version 1.12)Go version:       go1.15.6Git commit:       Built:            OS/Arch:          linux/loong64Experimental:     falsecontainerd:Version:          1.4.3-1-g6fbe2f9GitCommit:        6fbe2f9a8e085ffeb72c00027c4f9**********runc:Version:          1.0.0-rc93+devGitCommit:        docker-init:Version:          0.19.0GitCommit:

2、docker运行：

sudo docker run hello-world

显示如下：

Unable to find image 'hello-world:latest' locally

WARNING: The requested image's platform (linux/loongarch64) does not match the detected host platform (linux/loong64) and no specific platform was requestedHello 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 theexecutable that produces the output you are currently reading.4. The Docker daemon streamed that output to the Docker client, which sent itto your terminal.To try something more ambitious, you can run an Ubuntu container with:$ docker run -it ubuntu bashShare images, automate workflows, and more with a free Docker ID:https://hub.docker.com/For more examples and ideas, visit:https://docs.docker.com/get-started/
