The last one has been shared , How to deploy a harbor service , as well as harbor Introduction of the platform .

This article introduces how to give harbor Warehouse push image .

1 Explanation of the scene

The push scenario is often ：Harbor Set up in A machine (centos System ),docker Installed in the B machine (centos System ), Now in B The machine is packed and pushed to A machine .

But what? , In this case , I was in harbor The machine demonstrated docker Push to harbor, It is no different from the above scene , But the above scenario is pushed by different machines , My side is pushed by the same machine , But the operation process is the same .

2  Configure push docker

If b The image should be pushed to a On the machine , that b On the machine docker The image source needs to be configured , The mirror source points to a machine .

Set profile ：/etc/docker/daemon.json

configure ：

{
  "registry-mirrors": ["https://k1ktap5m.mirror.aliyuncs.com"],
  "insecure-registries": ["http://192.168.211.5:80"]
}

1. registry-mirrors The configuration is to accelerate the image source ,
2. insecure-registries Configuration is a The image source address of the machine , Be careful , Do not omit http and 80 port （ This port is harbor.yml The configuration of http port ）, Otherwise, the push will fail

3 push

3.1 Get ready

First pull down a mirror image for experiment ：

docker pull nginx

3.2 Mark image

Mark the image to be pushed , The format of the marking command is as follows ：

docker tag SOURCE_IMAGE[:TAG] 192.168.211.5:80/library/REPOSITORY[:TAG]

Explain a little bit ：

1. SOURCE_IMAGE[:TAG] At present docker An existing version of the image
2. library It means harbor The name of a certain project in it , Indicates that the image is pushed to this project
3. Be careful , among ip And ports should not be saved （ Especially in http In the agreement ）

For example, I want to push nginx To harbor Warehouse , The marking is as follows ：

docker tag nginx:latest 192.168.211.5:80/library/nginx:latest

3.3 Sign in docker（ It saves ）

Execute the following command

docker login 192.168.211.5:80

Log out docker The order of ：

docker logout

Log in as follows ：

[[email protected] harbor]# docker login 192.168.211.5:80
Username: admin
Password: 
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded

3.4  Push the mirror

Give it to me. harbor The format of the push image command is as follows ：

docker push 192.168.211.5:80/library/REPOSITORY[:TAG]

Just look at the order ,docker push The latter is actually the time of marking .

For example, I want to push the image marked on it , The order is as follows ：

docker push 192.168.211.5:80/library/nginx:latest

The log is as follows ：

[[email protected] harbor]# docker tag nginx:latest 192.168.211.5:80/library/nginx:latest
[[email protected] harbor]# docker push 192.168.211.5:80/library/nginx:latest
The push refers to repository [192.168.211.5:80/library/nginx]

Error model ：
