ArmSoM-W3应用开发之安装docker


1. 简介

  • RK3588从入门到精通系列专题

  • 开发板:ArmSoM-W3

  • Kernel:5.10.160

  • OS:Debian11

  • 本⽂介绍ArmSoM-W3在Debian11下如何安装使用docker

 

2.Rockchip 平台系统运行docker

Docker运行对内核配置有要求,需要 kernel 开启 cgroups、namespace、netfilter、overlayfs 等功能的⽀持,这些配置打开才满足docker运行的要求。

ArmSoM发布的普通固件一般不满足 Docker 的运行要求,如果有需求可以用我们配置过的内核固件,或者按照下文自己配置。

 

2.1 kernel配置

Docker开源团队提供了一个检测脚本,用以检测内核配置是否符合Docker运行的要求,下载脚本到SDK源码kernel目录下。

输入如下命令:

chmod 777 check-config.sh
​
./check-config.sh .config

 

注意:.config需要在内核配置完后才会生成

得到如下打印:

lhd@ydtx:~/project_code/3588/3588_linux5.10_v1.0.5/kernel$ ./check-config.sh .config
info: reading kernel config from .config ...

Generally Necessary是内核必须配置项,Optional Features是可选配置项

如果检测Generally Necessary下面的结果是missing或者enabled (as module),都可以去对应配置那设置为Y。

 

2.2 Debian 配置

Debian 默认使⽤ iptables-nft,⽽ docker 默认使⽤ iptableslegacy,故需要配置 iptables 使⽤ legacy 版本,可以通过以下命令进⾏切换:

# 使⽤ iptables-legacy
update-alternatives --set iptables /usr/sbin/iptables-legacy
update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy
# 使⽤ iptables-nft
update-alternatives --set iptables /usr/sbin/iptables-nft
update-alternatives --set ip6tables /usr/sbin/ip6tables-nft

 

 

2.3 安装Docker

在RK3588上安装Docker,按照以下步骤进行操作:

  1. 更新系统:

    在开始安装Docker之前,确保系统是最新的。运行以下命令:

    sudo apt update
    sudo apt upgrade

     

  2. 安装依赖项:

    安装Docker所需的一些依赖项:

    sudo apt install -y apt-transport-https ca-certificates curl software-properties-common

     

  3. 添加Docker官方GPG密钥:

    通过添加Docker官方的GPG密钥来信任官方存储库:

    curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

     

  4. 设置Docker存储库:

    添加Docker存储库到APT源列表中:

    echo "deb [signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

     

  5. 安装Docker引擎:

    更新APT软件包索引并安装Docker引擎:

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

     

    启动Docker服务:
  6. 安装完成后,启动Docker服务:

    sudo systemctl start docker

     

    还可以将Docker设置为在系统启动时自动启动:

    sudo systemctl enable docker

     

  7. 验证安装:

    运行以下命令以验证Docker是否正确安装:

    sudo docker pull hello-world
    sudo docker run hello-world

     

 

如果一切顺利,应该能够看到hello-world容器成功运行。
