Uploading to a docker hub

This tutorial will guide you through an upload to a dockerhub.

Generate a docker image

Quarkus

Generate the maven artifact:

1. For a non native executable (JVM):

   mvn package
   

2. For a native docker image:

   mvn package -Pnative -Dquarkus.native.container-runtime=docker
   

Quarkus can generate more images, learn here.

Create the docker image in the image local repository:

1. For a JVM image:

   docker build -f src/main/docker/Dockerfile.jvm -t smartgates/summary-mock .
   

2. For a native image:

   docker build -f src/main/docker/Dockerfile.native -t smartgates/summary-mock .
   

Tag image

We need to adjust our tags to the docker hub expected tags. In order to do so we can use the tag command:

docker tag smartgates/summary-mock smartgates/summary-mock:v0.1

Note: You cannot upload a image with a nonexistent tag unless you use the admin user. If you feel that a custom tag would be useful contact the docker-hub administrator.

Push image

If you have a problem in this section check if it is related with permission management. If it is go see the docker-hub admin.

Login

You have to be logged in as a valid user in order to upload an image.

docker login -u rpardom

Push

docker push smartgates/summary-mock:v0.1
