装好Harbor后，docker连接本地仓库报错。
[root@master1 v2]# docker login dsp.images.hub:11180
Username: admin

Error response from daemon: Get https://node4:11180/v1/users/: http: server gave HTTP response to HTTPS client

需要配置vim /usr/lib/systemd/system/docker.service
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network.target firewalld.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 --insecure-registry=heheda.images.hub:11180
ExecReload=/bin/kill -s HUP $MAINPID
# 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
# Uncomment TasksMax if your systemd version supports it.
# Only systemd 226 and above support this version.
#TasksMax=infinity
TimeoutStartSec=0
# 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
然后重启docker
systemctl daemon-reload systemctl restart docker
另外，记得配置hosts的关于dsp.images.hub的映射。
docker v18的话：
{"data-root":"/data/docker","insecure-registries":["11.68.0.0/16","heheda.images.hub:11180"],"registry-mirrors":["http://mirror.kce.sdns.ksyun.com"]}
