Container Registry: building and pushing image

GitLab CI/CD
1

Replace this template with your information

As the manual on gitlab it describes how to build image and push to repository

docker build -t gitlab.example.com:5050/group/app .

this command works fine, I am building the image

But the problem is with pushing the image to repository

docker push gitlab.example.com:5050/group/app

  • What are you seeing, and how does that differ from what you expect to see?

Using default tag: latest
The push refers to repository [gitlab.example.com:5050/group/app]
Get “https://gitlab.example.com:5050/v2/”: dial tcp xx.xx.xx.xx:5050: connect: connection refused

  • What version are you on? Are you using self-managed or GitLab.com?
    • GitLab (Hint: /help):
    • Runner (Hint: /admin/runners):

I am using self-managed self-hosted Gitlab and the latest version

Describe your question in as much detail as possible:

Wha dose this error means that the /v2 Service is Unavailable? I cant push the image to the remote repository.

  • Add the CI configuration from .gitlab-ci.yml and other configuration if relevant (e.g. docker-compose.yml)

Docker file:

FROM adoptopenjdk/openjdk11:alpine-slim
MAINTAINER myemail@gmail.com

COPY target/app.jar app.jar
ENTRYPOINT ["java","-jar","/app.jar"]
  • What troubleshooting steps have you already taken? Can you link to any docs or other resources so we know where you have been?

running command docker images show the image is create and listed
