CentOS 7 builds Docker private warehouse

Docker's private warehouse was unsuccessful during the learning of Docker, because the CentOS 6.x and CentOS 7 default introduced support for HTTPS authentication, and each time the push and pull errors were made, today is the weekend, The use of a day of repeated testing and online case integration, is finally successful, but also to take this opportunity to learn Docker friends help.

Personal humble Opinion: Bo friends in the practice of the proposed CentOS 7.x system, do not recommend the CentOS 6.x system

First, prepare

Address planning:

Docker Private Warehouse Address: 192.168.0.109Docker Client Address: 192.168.0.110

1. Activating the network card

# vim/etc/sysconfig/network-scripts/ifcfg-eno16777728 Modify this line onboot=yes#/etc/init.d/network restart

2. Turn off the local firewall and set the boot not self-booting

# systemctl Stop firewalld.service# systemctl disable Firewalld.service

3. Close the local SELinux firewall

# Vi/etc/sysconfig/selinux selinux=disabled# Setenforce 0

4. Installing Ifconfig Tools

# yum Install Net-tools

Second, installation

1. Installing Docker

# yum install docker# Yum Upgrade device-mapper-libs# service Docker start# Chkconfig Docker on

2. Local private Warehouse Registry

3. Run a container based on a private warehouse image

[[email protected] ~]# docker run -d -p 5000:5000 -v /opt/data/ Registry:/tmp/registry docker.io/registrybb2c0d442df94e281479332c2608ef144f378e71743c5410e36b80c465771a95 [[email protected] ~]# docker ps -acontainer id         IMAGE                        COMMAND              CREATED              STATUS              PORTS                      NAMESbb2c0d442df9        docker.io/registry:latest     "Docker-registry"    10 seconds ago      up 7 seconds         0.0.0.0:5000->5000/tcp   serene_hopper

4. Access to private warehouses

[[email protected] ~]# Curl 127.0.0.1:5000/v1/search{"Num_results": 0, "Query": "", "Results": []}//Private Warehouse is empty, no new image is submitted to the warehouse

5. Download an SSH image from the Docker hub

[[email protected] ~]# docker search -s 10 sshname                                DESCRIPTION   STARS      OFFICIAL   AUTOMATEDdocker.io: docker.io/fedora/ssh                  18                    [ok][[email protected]  ~]# docker pull fedora/sshtrying to pull repository docker.io/fedora/ SSH&NBSP, ..... 2AEB2B6D9705: DOWNLOAD COMPLETE 511136EA3C5A: DOWNLOAD COMPLETE 00A0C78EEB6D:  download complete 834629358fe2: download complete 571e8a51403c: download  complete&nbsP;87D5D42E693C: DOWNLOAD COMPLETE 92B5EF05FE68: DOWNLOAD COMPLETE 92D3910DC33C:  Download complete cf2e9fa11368: Download complete Status: Downloaded  newer image for docker.io/fedora/ssh:latest[[email protected] ~]# docker  imagesrepository             tag                  IMAGE ID             CREATED              VIRTUAL SIZEdocker.io/registry      latest              24dd746e9b9f         3 days ago           413.8&nbsP mbdocker.io/fedora/ssh   latest               2aeb2b6d9705        9 days ago           254.4 mb

6. Create a mirrored link or label the underlying image

[[Email protected] ~]# docker tag docker.io/fedora/ssh 127.0.0.1:5000/ssh[[email  protected] ~]# docker imagesREPOSITORY              TAG                  IMAGE ID             CREATED             VIRTUAL  sizedocker.io/registry     latest               24dd746e9b9f        3 days  ago          413.8 MBdocker.io/fedora/ssh    latest               2aeb2b6d9705        9 days ago          254.4  mb127.0.0.1:5000/ssh     latest               2aeb2b6d9705        9 days ago           254.4 mb

7. Modify the Docker configuration file to make a private warehouse URL

[[email protected] ~]# Vim/etc/sysconfig/docker Modify this line options= '--selinux-enabled--insecure-registry 192.168.0.109:5000 ' [[email protected] ~]# service Docker restartredirecting to/bin/systemctl restart Docker.service

8. Submit the image to the local private warehouse

[[email protected] ~]# docker push  127.0.0.1:5000/sshthe push refers to a repository [127.0.0.1:5000/ssh]  (len :  1) sending image listpushing repository 127.0.0.1:5000/ssh  (1 tags) 511136ea3c5a: image successfully pushed 00a0c78eeb6d: image successfully  pushed 834629358fe2: image successfully pushed 571e8a51403c: image  successfully pushed 87d5d42e693c: image successfully pushed 92b5ef05fe68:  image successfully pushed 92d3910dc33c: image successfully pushed  cf2e9fa11368: image successfully pushed 2aeb2b6d9705: image successfully  pushed pushing tag for rev [2aeb2b6d9705] on {http://127.0.0.1:5000/v1/ Repositories/ssh/tags/latest} 

9. See if there is a corresponding mirror in the private warehouse

[[email protected] ~]# Curl 127.0.0.1:5000/v1/search{"Num_results": 1, "Query": "", "results": [{"description": "", "name ":" Library/ssh "}]}

10. View the mirrored storage directory and files

[Email protected] ~]# TREE/OPT/DATA/REGISTRY/REPOSITORIES//OPT/DATA/REGISTRY/REPOSITORIES/└──LIBRARY└──SSH ├──_index_images├──json├──tag_latest└──taglatest_json2 directories, 4 files

Third, download the existing image from the private warehouse

1. Log in to another Docker client

[[email protected] ~]# ssh [email protected]the authenticity of host ' 192.168.0.110 (192.168.0.110) ' can ' t be established. ECDSA Key fingerprint is 5b:81:4b:66:d6:dd:48:16:9f:85:58:72:21:bd:ba:39.are you sure you want to continue connecting (yes /no)? yeswarning:permanently added ' 192.168.0.110 ' (ECDSA) to the list of known hosts. [email protected] ' s password:last login:sun Apr 14:39:51 from 192.168.0.103

2. Modify the Docker configuration file

[[email protected] ~]# Vim/etc/sysconfig/docker Modify this line options= '--selinux-enabled--insecure-registry  192.168.0.109:5000 '//Add private warehouse address [[email protected] ~]# service Docker restartredirecting to/bin/systemctl restart Docker.service

3. Download the existing image from the private warehouse

[[Email protected] ~]# docker pull 192.168.0.109:5000/sshtrying to pull  REPOSITORY 192.168.0.109:5000/SSH&NBSP, ..... 2AEB2B6D9705: DOWNLOAD COMPLETE 511136EA3C5A: DOWNLOAD COMPLETE 00A0C78EEB6D:  download complete 834629358fe2: download complete 571e8a51403c: download  complete 87d5d42e693c: download complete 92b5ef05fe68: download complete  92d3910dc33c: download complete cf2e9fa11368: download complete status:  downloaded newer image for 192.168.0.109:5000/ssh:latest[[email protected]  ~]# docker imagesREPOSITORY                TAG                  image id         &Nbsp;  created             virtual  SIZE192.168.0.109:5000/ssh   latest               2aeb2b6d9705        9 days ago           254.4 mb

Iv. browser access to the warehouse
