Original link address: "Advanced articles" docker Image Warehouse (20)

The second step of the three steps is to check the image warehouse and learn from docker warehouses. There are two kinds of warehouses. Other people's warehouses are also called public warehouses, and their own warehouses are also called private warehouses. The biggest difference between the public warehouse and the private warehouse is the network speed, the public warehouse from the public network, the private warehouse is from the local area network, the speed difference, the security, the public certainly does not have the private security, saves on own hard disk is the most stable. In fact, in the intermediate time, I already talked about the creation of docker warehouse, this time using mac to achieve the creation of docker warehouse. Source code: https://github.com/limingios/msA-docker

Public warehouse

The most authoritative public warehouse is hub.docker.com.

Package docker tag zookeeper:3.5 zhugeaming/zookeeper:3.5docker logindocker push zhugeaming/zookeeper:3.5

Private Warehouse (1)

Https://hub.docker.com/_/registry/

Docker pull registry:2

Installation instructions

Official installation instructions

Docker run-d-p 5000R 5000-- name registry registry:2

Push to local registrydocker tag zookeeper:3.5 localhost:5000/zookeeper:3.5docker push localhost:5000/zookeeper:3.5

In the production environment, it can not meet the requirements, single sign-on, one server has a problem, the other server is very difficult to host, it does not have an interface, it is not very convenient for him to interact.

So there is a new harbor in the industry, which is more suitable for the production environment.

Private Warehouse (2)

Https://github.com/goharbor/harbor/

Looking down in detail, I finally gave up installing harbor directly under mac and installed harbor through the virtual machine of vagrant.

Preparatory work

Select offline installation

Cp Downloads/harbor-offline-installer-v1.6.1.tgz ~ / app/cd ~ / apptar-xvf harbor-offline-installer-v1.6.1.tgz

Modify the configuration file

Modify the red part

Cd harborllvi harbor.cfg

Convenient management, mac system management, modify storage path

Vi docker-compose.yml

Installation

Weird problem

Want to install a harbor on mac and download harbor-offline-installer-v1.6.1.tgz

Put the file in the / user/liming/app/ directory of the mac book, and unzip and modify the path to the configuration file and mount the file. When running install, you must add sudo, which is responsible for insufficient permissions. After adding sudu, you can install it normally and successfully. But the rest of the problem comes, the container inside cannot access the mounted configuration file, indicating that the permissions are insufficient. In order to make up for the lack of permissions, I have made configurations in docker-compose.yml and added them.

Privileged: true, but it doesn't work. I've been bothered for a few days that there is no docker around me. Help me with the answer.

Vagrant installation

Https://github.com/limingios/msA-docker/tree/master/vagrant/harbor

Modify host file and port without modifying port vi harbor.cfg

Vi docker-compose.yml

Install. / install.sh

Browse

Ifconfig

Visit harbor

Http://172.28.128.3:8888

User name: admin

Password: Harbor12345

All users exposed by library can push

Add project micro-service, private project

Click on the project to enter the project.

Adding a member project administrator equals admin developer equals push and pull permissions to the image of the project visitors equals only pull permissions

Copy function

In the production environment, many computer rooms, the network speed between each server room is very fast, but across the computer room, the stability and speed of the network speed may be poor. Each computer room deploys a harbor through a central harbor. When there is a mirror to automatically synchronize other servers, replication rules can be specific to the project, and each project has its own replication rules.

Create a user

Add member

Assign developers

Harbor is actually very simple to operate, and you can understand it by clicking on it at will.

Local micro-service image push

Now find a way to push all the images to mico-service.

Host file modification sudo vi / etc/hosts

Upload basic image

Hub.idig88.com has configured the foundation

Docker tag java:openjdk-8 hub.idig88.com:8888/micro-service/java:openjdk-8

The push refers to repository [hub.idig88.com:8888/micro-service/java] Get https://hub.idig88.com:8888/v2/: http: server gave HTTP response to HTTPS client configuration address: login to the server.

Vi / usr/lib/systemd/system/docker.service service docker restart

Configuration address: native mac. Click app& Restart after modification

Upload the basic image docker login http://hub.idig88.com:8888-u liming-p password docker push hub.idig88.com:8888/micro-service/java:openjdk-8docker tag python:3.6 hub.idig88.com:8888/micro-service/python:3.6docker push hub.idig88.com:8888/micro-service/python:3.6 again

Push micro-services to the warehouse

Now that the basic image is pushed to the image repository, you need to modify the corresponding dockerfile file and change the name of the basic image. Modify the configuration file

6 micro-service Dockerfile

From hub.idig88.com:8888/micro-service/

6 sh script modifications added push function

View the warehouse

All 8 images are in place.

PS: after 2 days and no less than 20 hours, I finally gave up installing harbor under mac. Always keep in mind that mac is just an editor. Don't install everything on it. In many cases, it is more similar to a generation environment through a virtual machine. After talking about the docker repository this time, start the service orchestration tool next time. It feels so good!
