In nexus 3, there is no default user who can deploy Maven private server, only admin and anonymous users. To enable a role to deploy maven, you need to add all permissions of anonymous role and the following permissions:

4. Installing harbor

4.1 download the installation package: https://github.com/goharbor/harbor/releases

4.2. Upload to / usr/local/docker / directory

Unzip tar-zxvf harbor-offline-installer-v1.9.1-rc1.tgz

4.4. Enter the harbor directory to modify the harbor.yml file

hostname: 192.168.100.102
http:
  port: 8090
harbor_admin_password: Harbor12345

4.5. Execute install.sh.

Post startup access: http://192.168.100.101:8090 User name: admin Password: Harbor 12345

4.6. Configure the client

##Create without this file
vim /etc/docker/daemon.json

{
  "registry-mirrors":[
     "https://registry.docker-cn.com"
  ],
  "insecure-registries":[
   "192.168.100.101:8090"
  ]
}
Note: the file must conform to JSON specification, otherwise docker will not start

4.7 restart service

 systemctl daemon-reload
 systemctl restart docker

4.8. Check private server configuration

docker info

4.9 make image and submit it to harbor warehouse

##Pull nginx
docker pull nginx
## Mark mirror in project   
## docker tag SOURCE_IMAGE[:TAG] 192.168.100.101:8090/itchao-saas/IMAGE[:TAG]
docker tag nginx:latest 192.168.100.101:8090/itchao-saas/nginx:latest
## Sign in
docker login 192.168.100.101:8090 -u admin -p Harbor12345
## Push image to current project
## docker push 192.168.100.101:8090/itchao-saas/IMAGE[:TAG]
docker push 192.168.100.101:8090/itchao-saas/nginx:latest

5. Docker compose setting network

Create a network in advance

##Create network
docker network create <Network Name>
##View existing networks
docker network list

Specify the network in docker-compose.yml

networks:
  default:
    external:
      name: myapp
