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

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
/opt                u:object_r:rootfs:s0
/usr                u:object_r:rootfs:s0
/lib                u:object_r:rootfs:s0

3.编译烧录镜像

./build.sh --product-name rk3568 --ccache --target-cpu arm64

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

{
  "Cgroups": [
    {
      "UID": "system",
      "GID": "system",
      "Mode": "0755",
      "Controller": "blkio",
      "Path": "/dev/blkio"
    },
    {
      "UID": "system",
      "GID": "system",
      "Mode": "0755",
      "Controller": "cpu",
      "Path": "/dev/cpu"
    },
    {
      "Mode": "0555",
      "Path": "/dev/cpuacct",
      "Controller": "cpuacct"
    },
    {
      "UID": "system",
      "GID": "system",
      "Mode": "0755",
      "Controller": "cpuset",
      "Path": "/dev/cpuset"
    },
    {
      "UID": "system",
      "GID": "system",
      "Mode": "0755",
      "Controller": "memory",
      "Path": "/dev/memcg"
    },
    {
      "UID": "system",
      "GID": "system",
      "Mode": "0755",
      "Controller": "schedtune",
      "Path": "/dev/stune"
    },
    {
      "GID": "system",
      "UID": "system",
      "Mode": "0755",
      "Controller": "devices",
      "Path": "/dev/devices"
    },
    {
      "GID": "system",
      "UID": "system",
      "Mode": "0755",
      "Controller": "freezer",
      "Path": "/dev/freezer"
    },
    {
      "GID": "system",
      "UID": "system",
      "Mode": "0755",
      "Controller": "hugetlb",
      "Path": "/dev/hugetlb"
    },
    {
      "GID": "system",
      "UID": "system",
      "Mode": "0755",
      "Controller": "net_cls",
      "Path": "/dev/net_cls"
    },
    {
      "GID": "system",
      "UID": "system",
      "Mode": "0755",
      "Controller": "net_prio",
      "Path": "/dev/net_prio"
    },
    {
      "GID": "system",
      "UID": "system",
      "Mode": "0755",
      "Controller": "perf_event",
      "Path": "/dev/perf_event"
    },
    {
      "GID": "system",
      "UID": "system",
      "Mode": "0755",
      "Controller": "pids",
      "Path": "/dev/pids"
    },
    {
      "GID": "system",
      "UID": "system",
      "Mode": "0755",
      "Controller": "rdma",
      "Path": "/dev/rdma"
    }
  ],
  "Cgroups2": {
    "UID": "root",
    "GID": "root",
    "Mode": "0600",
    "Path": "/dev/cg2_bpf"
  }
}

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 /

  • 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

7.docker环境准备

# 创建docker运行需要的目录
mkdir /system/etc/docker
mkdir /data/var
mkdir /data/run
mkdir /data/tmp
mkdir /data/opt
mkdir /data/etc
mkdir /data/etc/docker
mkdir /data/usr
mkdir /mnt/f2fs

# 挂载刚刚已经被f2fs格式化的sd卡设备，可以用blkid查看到具体的名称
mount /dev/block/vol-179-97 /mnt/f2fs/

# 创建一个1GB大小的tmpfs文件系统，并将其挂载到"/sys/fs/cgroup"目录下，以供cgroup机制使用。
mount tmpfs /sys/fs/cgroup -t tmpfs -o size=1G
mkdir /sys/fs/cgroup/blkio
mkdir /sys/fs/cgroup/cpu
mkdir /sys/fs/cgroup/cpuacct
mkdir /sys/fs/cgroup/cpuset

mount -t cgroup -o schedtune,nodev,noexec,nosuid cgroup /sys/fs/cgroup/schedtune

# 设置DNS名称服务器和docker image注册表
echo "{\"registry-mirrors\":[\"https://docker.mirrors.ustc.edu.cn\"],\"experimental\":false,\"storage-driver\": \"overlay2\",\"data-root\": \"/mnt/f2fs\"}" > /etc/docker/daemon.json

# 临时关闭 SELinux 安全模式
setenforce 0

8.运行docker

dockerd -D -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock &

10.OpenHarmony系统重启后重新开启docker

hdc shell 

mount -o rw,remount -t auto /
mkdir /mnt/f2fs

blkid
df -h

# 挂载sd卡到/mnt/f2fs/
