Centos7 docker build private repository registry

Centos7 docker build private repository registry

Environment Planning:

Docker private repository address: 192.168.0.167

Docker client address: 192.168.0.167

· Disable firewall and selinux

systemctlstopfirewalld.service systemctldisablefirewalld.service #vi/etc/sysconfig/selinux SELINUX=disabled #setenforce0

Server

1. Install and start docker

yum-yinstalldocker servicedockerstart chkconfigdockeron

2. Pull the local private repository registry

[root@localhost~]#dockerpullregistry Tryingtopullrepositorydocker.io/registry... 24dd746e9b9f:Downloadcomplete 706766fe1019:Downloadcomplete a62a42e77c9c:Downloadcomplete 2c014f14d3d9:Downloadcomplete b7cf8f0d9e82:Downloadcomplete d0b170ebeeab:Downloadcomplete 171efc310edf:Downloadcomplete 522ed614b07a:Downloadcomplete 605ed9113b86:Downloadcomplete 22b93b23ebb9:Downloadcomplete 2ac557a88fda:Downloadcomplete 1f3b4c532640:Downloadcomplete 27ebaac643a7:Downloadcomplete ce630195cb45:Downloadcomplete Status:Downloadednewerimage for docker.io/registry:latest

3. view the registry Image

[root@localhost~]#dockerimages docker.io/busyboxlatest0064fda8c45d5daysago1.113MB docker.io/registrylatest105c6c9299d95daysago423.3MB docker.io/centoslatestce20c473cd8a6daysago172.3MB

4. Run containers based on private repository Images

By default, the repository is stored in the/tmp/registry directory of the container. If the container is deleted, the image stored in the container will also be lost, therefore, we usually specify a local directory to be mounted to the/tmp/registry directory of the container!

· The default storage path of registry is/tmp/registry, which is only a temporary directory and will disappear after a period of time

· Use the-v parameter to specify a local persistent path,

[root@localhost~]#dockerrun-d-p5000:5000-v/opt/data/registry:/tmp/registrydocker.io/registry bb2c0d442df94e281479332c2608ef144f378e71743c5410e36b80c465771a95 root@localhost~]#dockerps-a CONTAINERIDIMAGECOMMANDCREATEDSTATUSPORTSNAMES bb2c0d442df9docker.io/registry:latest "docker-registry" 10secondsagoUp7seconds

5. Access a private Repository

[root@localhost~]#curl127.0.0.1:5000/v1/search { "num_results" :0, "query" : "" , "results" : []} # The Private repository is empty. No new image is submitted to the repository.

6. Pull an image from Docker HUB to test

[root@localhost~]#dockerpullbusybox [root@localhost~]#dockerimages REPOSITORYTAGIMAGEIDCREATEDVIRTUALSIZE docker.io/busyboxlatest0064fda8c45d5daysago1.113MB docker.io/registrylatest105c6c9299d95daysago423.3MB docker.io/centoslatestce20c473cd8a6daysago172.3MB

7. Create an image link to tag the basic image

[root@localhost~]#dockertagdocker.io/busybox192.168.0.167:5000/busybox [root@localhost~]#dockerimages REPOSITORYTAGIMAGEIDCREATEDVIRTUALSIZE 192.168.0.167:5000/busyboxlatest0064fda8c45d5daysago1.113MB docker.io/busyboxlatest0064fda8c45d5daysago1.113MB docker.io/registrylatest105c6c9299d95daysago423.3MB docker.io/centoslatestce20c473cd8a6daysago172.3MB

8. Modify the docker configuration file and specify the private repository url

[root@localhost~]#vim/etc/sysconfig/docker Modify this line OPTIONS= '--insecure-registry192.168.0.167:5000' [root@localhost~]#servicedockerrestart

9. Upload the image to a local private Repository

dockerpush192.168.0.167:5000/busybox

10. Check whether the private repository has the corresponding image

[root@localhost~]#curl192.168.0.167:5000/v1/search { "num_results" :1, "query" : "" , "results" :[{ "description" : "" , "name" : "library/busybox" }]}

11. view the storage directories and files of images

[root@localhost~]#tree/opt/data/registry/repositories/ /opt/data/registry/repositories/ └──library └──ssh ├──_index_images ├──json ├──tag_latest └──taglatest_json 2directories,4files

Client

1. Install and start docker

yum-yinstalldocker servicedockerstart chkconfigdockeron

2. Modify the docker configuration file and specify the private repository url

[root@localhost~]#vim/etc/sysconfig/docker Modify this line OPTIONS= '--insecure-registry192.168.0.167:5000' [root@localhost~]#servicedockerrestart

3. Test and download the uploaded image.

[root@localhost~]#dockerpull192.168.0.167:5000/busybox [root@localhost~]#dockerimages REPOSITORYTAGIMAGEIDCREATEDVIRTUALSIZE 192.168.0.167:5000/busyboxlatest0064fda8c45d5daysago1.113MB docker.io/registrylatest105c6c9299d95daysago423.3MB docker.io/centoslatestce20c473cd8a6daysago172.3MB docker.io/atcol/docker-registry-uilatestd838355ad9036monthsago890.5MB
