本文将介绍如何在OpenHarmony内核上运行docker容器。

1.环境和设备

系统版本： 3.2release（64位）
OpenHarmony内核版本：5.10
标准系统设备： DAYU200
Docker：18.03.1 （64位）
sd卡一张

2.准备支持Docker容器的OpenHarmony内核

1.检测DAYU200 3568 OpenHarmony3.2release内核对docker的支持

下载检测脚本check-config.sh

2.在编译命令./build.sh --product-name rk3568 --ccache --target-cpu arm64编译arm64位系统情况下

进入out/kernel/src_tmp/linux-5.10下执行scripts/extract-ikconfig boot_linux.img > /home/.config生成boot_linux.img内核镜像的配置文件，配置文件此时输入到了/home/.config
执行脚本 ./check-config.sh .config

3.修改源码内核配置kernel/linux/config/linux-5.10/rk3568/arch/arm64_defconfig

将必选和可选的配置都打开，修改内核配置

4.添加Docker运行需要的目录’run’, ‘var’, ‘opt’, ‘usr’。修改build/ohos/images/build_image.py

'run', 'var', 'opt', 'usr'

5.修改/base/security/selinux/sepolicy/base/system/file_contexts

/run                u:object_r:rootfs:s0
/var                u:object_r:rootfs:s0

4.安装docker容器引擎组件

1.hdc shell进入开发板终端在/etc/下创建cgroups.json,cgroups.json内容如下

2.安装docker静态二进制文件

# 下载docker static binaries 18.03.1
https://download.docker.com/linux/static/stable/aarch64/
若为32位选择armhf版。

# 解压并且加入环境变量
tar zxvf 到/system/bin下

# 给二进制文件执行权限
cd /system/bin/docker/
chmod 777 docker
chmod 777 docker-containerd-ctr
chmod 777 docker-init
chmod 777 docker-runc
chmod 777 docker-containerd
chmod 777 docker-containerd-shim
chmod 777 docker-proxy
chmod 777 dockerd
export PATH=$PATH:/system/bin/
export PATH=$PATH:/system/bin/docker/

5.格式化sd卡为f2fs文件系统

# 修改root目录下的权限使其可以进行文件操作
hdc shell mount -o rw,remount -t auto /
1.
2.

docker overlay filesystem推荐backing filesystem是未加密的f2fs。而RK3568的data分区是加密的ext4，可以通过micro sd card卡扩展RK3568的存储将sd card格式化为f2fs解决此问题。
准备一个sd卡，插入到DAYU200板子上

# 查看系统文件系统格式
blkid

# 查看系统文件系统和挂载情况
df -h

# 确定sd卡的名称,将其格式化sd卡为f2fs
# 卸载设备：如果设备已挂载，使用以下命令卸载设备：（请确保设备已成功卸载，不再出现任何输出。）
umount /dev/block/vol-179-97

# 执行mkfs.f2fs命令来创建F2FS文件系统：
mkfs.f2fs /dev/block/vol-179-97

格式化后先不要挂载sd卡

6.通过有线或者无线连接网络

将开发板连接网络

# 查看正在运行的
ifconfig

# 查看所有的网络接口 
ifconfig  -a

# 开启ip forward
echo "1" > /proc/sys/net/ipv4/ip_forward
