1. 前言

本文详细介绍如何在kylin v10上安装docker。系统环境如下：

dockder:        20.10.7
linux os:       kylinv 10 (GFB)
linux kernel:   4.19.90-52.23.v2207.gfb01.ky10.aarch64

2. 安装docker

2.1. 下载docker二进制包

wget https://mirror.nju.edu.cn/docker-ce/linux/static/stable/aarch64/docker-20.10.7.tgz

此处采用的是从南京大学开源镜像站下载，速度比较快，当然也可以直接从docker官网下载。

2.2. 解压docker二进制包

tar -zxvf docker-20.10.7.tgz && mv docker/* /usr/local/bin/ && rm -rf docker

2.3. 添加service文件

cat << EOF > /etc/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 containerd.service
Requires=docker.socket

[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
EOF

2.4. 添加docker.socket文件

cat << EOF > /etc/systemd/system/docker.socket
[Unit]
Description=Docker Socket for the API

[Socket]
ListenStream=/var/run/docker.sock
SocketMode=0660
SocketUser=root
SocketGroup=docker

[Install]
WantedBy=sockets.target
EOF

2.5. 启动docker engine服务

systemctl daemon-reload
systemctl enable docker.service
systemctl start docker.service

2.6. 验证docker是否安装成功

执行docker info命令，如果显示如下信息，则docker安装成功。
