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 https://github.com/moby/moby/blob/master/contrib/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'

追加docker在openharmony上正常运行所需的一些目录.png

4.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

修改file_contexts.png

 

3.编译烧录64位镜像

./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

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

# 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 /
# 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,后面步骤会挂载

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

mkdir /sys/fs/cgroup/pids
mkdir /sys/fs/cgroup/rdma
mkdir /sys/fs/cgroup/schedtune
mkdir /sys/fs/cgroup/systemd

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

 

运行docker.png

 

9.验证docker运行状态

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/
