简介： 下载并安装适用于ARM架构的Docker CE二进制文件，解压后移动至/usr/bin目录。创建docker组，配置systemd服务脚本（docker.service、docker.socket、containerd.service），重载systemd配置，启动并启用docker服务。编辑daemon.json配置存储驱动、镜像加速地址等，最后拉取所需镜像。

■ 下载arm架构二进制文件安装包

http://mirrors.163.com/docker-ce/linux/static/stable/aarch64/
docker-27.3.1.tgz                                  21-Sep-2024 01:36     66M

■ 解压二进制文件移动到 /usr/bin 目录

tar xvfz docker-27.3.1.tgz
ls -l docker
cp docker/* /usr/bin/

■ 测试启动

dockerd

■ 添加 docker 的 systemd 服务脚本

脚本参考自 https://github.com/docker/docker-ce

vim /usr/lib/systemd/system/docker.service

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target docker.socket firewalld.service containerd.service
Wants=network-online.target
Requires=docker.socket containerd.service

[Service]
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutStartSec=0
RestartSec=2
Restart=always

# Note that StartLimit* options were moved from "Service" to "Unit" in systemd 229.
# Both the old, and new location are accepted by systemd 229 and up, so using the old location
# to make them work for either version of systemd.
StartLimitBurst=3

# Note that StartLimitInterval was renamed to StartLimitIntervalSec in systemd 230.
# Both the old, and new name are accepted by systemd 230 and up, so using the old name to make
# this option work for either version of systemd.
StartLimitInterval=60s

# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity

# Comment TasksMax if your systemd version does not support it.
# Only systemd 226 and above support this option.
TasksMax=infinity

# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes

# kill only the docker process, not all processes in the cgroup
KillMode=process
OOMScoreAdjust=-500

[Install]
WantedBy=multi-user.target

■ 根据 docker.service 中 Unit.After 需求添加 docker.socket 脚本至 /usr/lib/systemd/system/

脚本参考自 https://github.com/docker/docker-ce

vim /usr/lib/systemd/system/docker.socket

[Unit]
Description=Docker Socket for the API

[Socket]
# If /var/run is not implemented as a symlink to /run, you may need to
# specify ListenStream=/var/run/docker.sock instead.
#ListenStream=/run/docker.sock
ListenStream=/var/run/docker.sock
SocketMode=0660
SocketUser=root
SocketGroup=docker

[Install]
WantedBy=sockets.target

■ 根据 docker.service 中 Unit.After 需求添加 containerd.service 脚本至 /usr/lib/systemd/system/

脚本参考自 https://github.com/containerd/containerd

vim /usr/lib/systemd/system/containerd.service

■ 重载 systemd 配置文件

systemctl daemon-reload

■ 创建 docker 组

groupadd docker

如不创建 docker 组在通过 systemctl 启动时会报错如下

Dependency failed for Docker Application Container Engine.
Job docker.service/start failed with result 'dependency'.

■ 启动 docker 服务

systemctl status docker
systemctl start docker
systemctl enable docker
systemctl restart docker

■ 配置合适的容器位置、网络镜像地址

vim /etc/docker/daemon.json
{
  "storage-driver": "overlay2",
  "registry-mirrors": [
    "https://2a6bf1988cb6428c877f723ec7530dbc.mirror.swr.myhuaweicloud.com",
    "https://docker.m.daocloud.io",
    "https://hub-mirror.c.163.com",
    "https://mirror.baidubce.com",

    "https://docker.rainbond.cc"
  ],
  "exec-opts": ["native.cgroupdriver=systemd"],
  "data-root": "/u01/docker"
}

■ 拉取想要的镜像

docker pull oraclelinux:8

如无法 pull 则需配置合适的镜像地址，或者下载容器镜像。
