docker18.09 快速添加harbor仓库地址的方法（不是安装harbor）和修改镜像容器存放位置（初始化安装docker时，不是迁移容器镜像）...

系统版本：centos7.6 系统内核： 4.4 docker版本：18.09 找到docker.server启动文件位置，打开后，修改 [root@243-ceshi ~]#  vim /usr/lib/systemd/system/docker.service [Unit] Description=Docker Application Container Engine Documentation=https://docs.docker.com #BindsTo=containerd.service. — 无需containerd。 After=network-online.target firewalld.service Wants=network-online.target [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 unix:// --graph /app/software --insecure-registry=hub.vrgv.com ExecReload=/bin/kill -s HUP $MAINPID TimeoutSec=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 supports 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 [Install] WantedBy=multi-user.target --graph：指定容器镜像存放位置 --insecure-registry：指定harbor仓库地址 另一种方法是配置/etc/docker/dameon.json文件，也可以的 [root@243-ceshi ~]# cat /etc/docker/daemon.json { "registry-mirrors": ["[""exec-opts": ["native.cgroupdriver=systemd"] }
