Jan 30, 2021

Problem

When we do docker push command like this:

[root@bswen-6 ~]# docker push 10.2.3.111:8080/argoproj/argocd:v1.8.3
The push refers to repository [1.2.3.111:8080/argoproj/argocd]

unauthorized: unauthorized to access repository: argoproj/argocd, action: push: unauthorized to access repository: argoproj/argocd, action: push

we get this :

unauthorized: unauthorized to access repository: argoproj/argocd, action: push: unauthorized to access repository: argoproj/argocd, action: push

The core error is : fatal: unauthorized to access repository

Why do this error happen? The docker repository url is correct, I am sure!!!

Environment

docker 20.10.2

Reason

This error happens because you have not correctly authenticated by your private docker repository, you should login the docker repository at first, then you can push your docker image to the repository.

Solution

First, authenticate with the docker command:

[root@bswen-k8s-app5 ~]# docker login 10.2.3.111:8080
Username: bswen
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

Input your username and password, if all pass, then you are authenticated.

Then push your docker image to the repo:

[root@bswen-k8s-app5 ~]# docker push 10.2.3.111:8080/argoproj/argocd:v1.8.3
The push refers to repository [1.2.3.111:8080/argoproj/argocd]
