Creating your Docker images

So far we have used a pre-built image with an operating system image. We will now show you how to create your own Docker image, containing EAP 7 and its required dependencies, such as the JDK environment.

In order to do that, we will use a Dockerfile, which is a text file that contains all the commands needed in order to build a specific image.

Note

The available set of commands are described in depth in the site's documentation: https://docs.docker.com/engine/reference/builder/.

Here we will discuss the set of commands required to create an EAP 7 image: create a file named Dockerfile and include the following content:

### Set the base image  
FROM jboss/base-jdk:8 
 
### File Author / Maintainer 
MAINTAINER "Francesco Marchioni" "[e-mail]" 
 
### Install EAP 7.0.0 
ADD build/jboss-eap-7.0.0.zip /tmp/ 
RUN unzip /tmp/jboss-eap-7.0.0.zip 
 
### Set Environment 
ENV JBOSS_HOME /opt/jboss/jboss-eap-7.0 
 
### Create EAP User 
RUN ...
