1. Log in to the system background

Open the browser and visit http://:8081/

Enter account password

Second, create a docker warehouse

Step 1: Create a warehouse

 

Step 2: Configure the warehouse

Set the warehouse name

Specify a unique name for the warehouse, and then choose http or https. This is just for testing, so go http

Note: The port must be determined.

 After the creation is successful, you can view it in the warehouse list

Step two: client configuration

Because http is used, you need to edit the docker configuration file on the client side, such as

vim /etc/systemd/system/multi-user.target.wants/docker.service

 

Find the ExecStart property and add --insecure-registry server IP:Docker warehouse port after dockerd

ExecStart=/usr/bin/dockerd --insecure-registry=ip:9021

Save, reload the configuration and restart the docker service

systemctl daemon-reload

systemctl restart docker

Three, client use

First docker login ip: 9021, enter the authorized account and password, and after the prompt is successful, you can docker push the image to the warehouse.

E.g

docker login -u admin -p 你的admin密码 192.168.88.131:9021

Client use error

An error will be reported at this time

Error response from daemon: Get http://192.168.88.131:9021/v1/users/: dial tcp 192.168.88.131:9021: connect: connection refused

solution

1. Is there any configuration in the docker configuration file?

      If there is no configuration, please follow the operation step two: configure the warehouse

2. Is the port of the docker warehouse mapped?

      Map out port 9021

docker run -p 8081:8081 -p 9021:9021 --privileged=true --name nexus -v /usr/local/docker/nexus/nexus-data:/nexus-data 8716903d1912

push mirror to private server

#先tag镜像，把镜像名变成包含本地仓库名（如192.168.88.131:9021）的镜像
#docker tag 本地镜像名:镜像tag 私有库地址/镜像名:镜像tag
docker tag centos_tomcat8:v1 192.168.88.131:9021/centos_tomcat8:v1

When pushing, you need to use docker push Private library address/mirror name: mirror tag

再push镜像至仓库中：
docker push 192.168.88.131:9021/centos_tomcat8:v1

pull Pull the mirror from the private server

docker pull 192.168.88.131:9021/centos_tomcat8:v1

At this point, it means that nexus has been installed successfully, and you can pull and push on the client.

       I encountered some problems when sorting out these two blog posts. Thanks to my enthusiastic colleague Yang and netizens for their support, and I feel the love of the technical people! Thank you very much!
