docker 指定版本rpm包安装

1.docker rpm包下载地址

# https://download.docker.com/linux/centos/7/x86_64/stable/Packages/

2.下载rpm包

# wget https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-18.06.0.ce-3.el7.x86_64.rpm 

3.安装docker

# 下载阿里的docker-ce源
# cd /etc/yum.repos.d/ && wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

# yum -y install docker-ce-18.06.0.ce-3.el7.x86_64.rpm

4.镜像加速配置

# mkdir -p /etc/docker/
# cat  >/etc/docker/daemon.json<<EOF
{
  "registry-mirrors": ["https://registry.docker-cn.com"]
}
EOF

5.指定docker目录启动

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

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
BindsTo=containerd.service
After=network-online.target firewalld.service containerd.service
Wants=network-online.target
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 --graph /home/meisoo/docker --insecure-registry=172.17.29.74 -H fd:// --containerd=/run/containerd/containerd.sock
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutSec=
RestartSec=
Restart=always

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

# Note that StartLimitInterval was renamed to StartLimitIntervalSec in systemd .
# Both the old, and new name are accepted by systemd  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  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

[Install]
WantedBy=multi-user.target
