Tech Tip #57 explained how to create your own Docker images. That particular blog specifically showed how to build your own WildFly Docker images on CentOS and Ubuntu. Now you are ready to share your images with rest of the world. That’s where Docker Hub comes in handy.
Docker Hub is the “distribution component” of Docker, or a place to store and search images. From the Getting Started with Docker Hub docs …
The Docker Hub is a centralized resource for working with Docker and its components. Docker Hub helps you collaborate with colleagues and get the most out of Docker.
Starting and pushing images to with Docker Hub is pretty straight forward.
- Pushing images to Docker Hub require an account. It can be created as explained here. Or rather easily by using
docker logincommand.wildfly-centos> docker login Username: arungupta Password: Email: arun.gupta@gmail.com Login Succeeded
Searching on WildFly shows there are 72 images:

Official images are tagged
jboss/wildfly. - In order to push your own image, it needs to be built as a named image otherwise you’ll get an error as shown:
2014/11/26 09:59:37 You cannot push a "root" repository. Please rename your repository in <user>/<repo> (ex: arungupta/wildfly-centos)
This can be easily done as shown:
wildfly-centos> docker build -t="arungupta/wildfly-centos" . Sending build context to Docker daemon 4.096 kB Sending build context to Docker daemon Step 0 : FROM centos ---> ae0c2d0bdc10 Step 1 : MAINTAINER Arun Gupta
docker buildcommand builds the image,-tspecifies the repository name to be applied to the resulting image. - Once the image is built, it can be verified as:

arungupta/wildfly-centos. - This image can then be pushed to Docker Hub as:
