Docker--------Registry Private Warehouse build [Http]

1. Background

      docker to use mirroring, Mirroring is typically downloaded from local, Docker hup public warehouses, and other third-party public repositories, generally for reasons of security and external network (wall) resource download rates that are not readily available at the enterprise level. So is there a way to store your own mirrored repositories? Build your own private warehouse----> Enterprise-Class environments.

2. Private warehouses have advantages:

One, to save the network bandwidth, for each image without everyone to the central warehouse to download, only need to download from the private warehouse;

Second, to provide the use of mirror resources, for the internal use of the image, pushed to the local private warehouse, for the company's internal personnel to use.

3. Environment:

[Email protected] ~]# cat/etc/redhat-release CentOS Linux release 7.2.1511 (Core) [[email protected] ~]# uname-r3.10.0- 327.36.3.el7.x86_64

4. Server IP Address

192.168.60.150

5. Installation:

* Install Docker

[email protected] ~]# Yum install Docker

* start Docker service

[[email protected] ~]# Systemctl start Docker

* set up Docker service boot

[[email protected] ~]# Systemctl enable Docker

* Pull registry image, for example, in Daocloud.io/registry this private mirror warehouse

[email protected] ~]# Docker pull Daocloud.io/registry

* Create local mirror storage directory

[Email protected] ~]# mkdir/data/local_docker_registry-p

* run the container, set the container name to Local_docker_registry, and hang it in the mirrored Docker image warehouse/var/lib/registry to the local/data/local_docker_registry directory. and expose 5000 ports,--restart=always Let it start when Docker starts

[email protected] ~]# Docker run--name local_docker_registry--restart=always-d-v/data/local_docker_registry:/var/ Lib/registry-p 5000:5000 Daocloud.io/registry

* test [with return means success]

[Email protected] ~]# Curl 192.168.60.150:5000/v2<a href= "/v2/" >moved permanently</a>.

6. Upload image to private warehouse test

* Write Dockerfile file

# Nginx # Version 1.0.1# Author lisea# Url https://lisea.cn# Base imgaefrom centos# maintainermaintainer lisea [email prot ected]# commandsrun rpm-ivh http://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpmRUN yum Install Nginx- Yrun echo "daemon off;" >>/etc/nginx/nginx.confrun echo "This is test nginx image" >/usr/share/nginx/html/index . htmlexpose 80CMD ["Nginx"]

* build a new image with Dockerfile to directly indicate registry and tags

[email protected] nginx]# Docker build-t 192.168.60.150:5000/nginx:1.0.1.

* Push upload image to private repository

[email protected] nginx]# Docker push 192.168.60.150:5000/nginx:1.0.1

* See if the image was uploaded successfully

[[email protected] nginx]# Curl 192.168.60.150:5000/v2/_catalog{"repositories": ["Nginx"]}

* Other servers use this image

[email protected] nginx]# Docker pull 192.168.60.150:5000/nginx:1.0.1

7. Related issues

* There may be an issue that cannot push mirroring to a private warehouse.     This is because the registry service We started is not secure and trustworthy. Solution:

1. You need to modify the Docker configuration file /etc/sysconfig/docker-network, add the following content,

docker_network_options= "--insecure-registry 192.168.60.150:5000"

2. Restart Docker

[Email protected] nginx]# Systemctl restart Docker

8. Summary

To demand-driven technology, the technology itself does not have a better point, only the division of business.
