在harbor本机或者其他主机可以使用docker login +域名 直接连接harbor主机仓库,不用在使用IP地址连接。
Harbor客户端:172.21.xxx.xxx harbor-images
CentOS Linux release 7.6.1810 (Core)
Docker 13.1.1
Docker compose 1.25.5
Harbor 1.5.0
Nginx客户端:172.21.ggg.ggg
CentOS Linux release 7.6.1810 (Core)
Docker 19.03.8
Docker compose 1.18.0
1.修改/etc/hosts文件
[root@harbor harbor]# vim /etc/hosts
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
172.21.xxx.xxx iZ8vb4u5g0xxxxxxxxxx harbor-images //添加登录域名
2.修改harbor目录下harbor.cfg文件:
必须在harbor目录下运行,否则会报错。
[root@harbor ~]# cd /mnt/app/harbor/harbor/
[root@harbor harbor]# docker-compose stop //停止harbor服务
[root@harbor harbor]# vim harbor.cfg
...
_version = 1.5.0
#The IP address or hostname to access admin UI and registry service.
#DO NOT use localhost or 127.0.0.1, because Harbor needs to be accessed by external clients.
hostname = harbor-images //修改为域名
[root@harbor harbor]# ./prepare //加载配置文件
3.修改/usr/lib/systemd/system/下的docker.service文件:
[root@harbor harbor]# vim /usr/lib/systemd/system/docker.service
[Unit]
Description=Docker Application Container Engine
Documentation=http://docs.docker.com
After=network.target
Wants=docker-storage-setup.service
Requires=docker-cleanup.timer
[Service]
Type=notify
NotifyAccess=main
EnvironmentFile=-/run/containers/registries.conf
EnvironmentFile=-/etc/sysconfig/docker
EnvironmentFile=-/etc/sysconfig/docker-storage
EnvironmentFile=-/etc/sysconfig/docker-network
Environment=GOTRACEBACK=crash
Environment=DOCKER_HTTP_HOST_COMPAT=1
Environment=PATH=/usr/libexec/docker:/usr/bin:/usr/sbin
ExecStart=/usr/bin/dockerd-current \
--add-runtime docker-runc=/usr/libexec/docker/docker-runc-current \
--default-runtime=docker-runc \
--exec-opt native.cgroupdriver=systemd \
--userland-proxy-path=/usr/libexec/docker/docker-proxy-current \
--init-path=/usr/libexec/docker/docker-init-current \
--seccomp-profile=/etc/docker/seccomp.json \
--insecure-registry=harbor-images \ //添加为域名
$OPTIONS \
[root@harbor harbor]# systemctl daemon-reload
[root@harbor harbor]# systemctl restart docker
[root@harbor harbor]# docker-compose start //启动harbor服务
注意:
这里添加的 --insecure-registry=IP/主机名 也是解决连接harbor时https报错的其中一步。

4.测试本机域名连接
[root@harbor harbor]# docker login harbor-images
Username (admin): admin
Password:
Login Succeeded //登录成功
1.修改/etc/hosts文件
[root@nginx ~]# cat /etc/hosts
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
172.21.ggg.ggg iZ8vbg29xxxxxxxxx
172.21.xxx.xxx harbor-images //增加harbor主机的IP及登录的域名
2.修改/etc/docker/目录下daemon.json文件
[root@nginx ~]# vim /etc/docker/daemon.json
{
"graph":"/mnt/app/docker/data",
"registry-mirrors": ["https://b34xxxxx.mirror.aliyuncs.com"],
"insecure-registries":["harbor-images"]
}
[root@nginx ~]# systemctl daemon-reload
[root@nginx ~]# systemctl restart docker
添加"insecure-registries":["harbor-images"]中harbor主机设置的登录域名,这里的insecure参数如果是写在/usr/lib/systemd/system/docker.service中,如上面harbor主机那样,那么就直接修改/usr/lib/systemd/system/docker.service中该项配置即可,这个参数只能在docker.service或者daemon.json其中一个配置文件中。
3.测试nginx客户端域名连接harbor主机:
[root@nginx ~]# docker login harbor-images
Authenticating with existing credentials...
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store
Login Succeeded //登录成功
如果更改完配置并且重启docker成功后还是无法使用域名连接harbor主机服务,可以尝试断开nginx客户端SSH连接,重新连接nginx客户端再进行域名连接harbor主机服务。
