docker及docker-compose离线安装

ubuntu离线安装

下载docker安装包，下载地址 https://download.docker.com/linux/static/stable/x86_64/

将下载的 docker-26.1.3.tgz放在tmp目录下，解压缩

tar -zxvf docker-26.1.3.tgz

将解压缩后的目录，全部拷贝到 /usr/bin目录下（特别提醒，不能将压缩包，拷贝到 /usr/bin 目录下再解压，会不生效）

cp -p docker/* /usr/bin
# 遇到提示，全部overwrite即可，如下图

将docker注册为系统服务
1. 将docker.service文件放到 /usr/lib/systemd/system/ 目录下
2. 将docker.socket文件放到 /usr/lib/systemd/system/ 目录下
  可以从在线安装docker的目录下，拷贝这两个文件，可以直接使用，简书插入不了附件，以下是这两个文件的内容
  docker.service

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target docker.socket firewalld.service containerd.service time-set.target
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
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.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.
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

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
SocketMode=0660
SocketUser=root
SocketGroup=docker

[Install]
WantedBy=sockets.target

给系统增加一个docker组

groupadd docker

重启守护进程

systemctl daemon-reload

启动docker

systemctl start docker

设置docker开启启动

systemctl enable docker

安装docker-compose

从 https://github.com/docker/compose/releases 下载linux环境包 docker-compose-Linux-x86_64

image.png
将下载的文件，拷贝到目标机器的 /usr/local/bin/ 目录下，将docker-compose-Linux-x86_64文件重命名为 docker-compse
给 docker-compose 文件授权 chmod +x /usr/local/bin/docker-compose
测试 docker-compse -v 即可以查看对应版本信息

centos离线安装

arm64离线安装（步骤与ubuntu一致，有几个点需要注意）

docker.service 内容用以下的

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

[Service]
Type=notify
ExecStart=/usr/bin/dockerd
ExecReload=/bin/kill -s HUP $MAINPID
LimitNOFILE=infinity
LimitNPROC=infinity
TimeoutStartSec=0
Delegate=yes
KillMode=process
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s

[Install]
WantedBy=multi-user.target

装好之后，pull镜像的时候如果出现报错：
Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: container_linux.go:318: starting container process caused "permission denied": unknown

解决方法：执行命令 yum remove podman
