Introduction

This tutorial will take you through the basic steps to create a docker image from an Entando core application. A more detailed guide with additional commands and configuration can be found here:

https://github.com/entando/entando-de-app (opens new window)

Setup

1. Clone the application at: https://github.com/entando/entando-de-app (opens new window) using

   git clone https://github.com/entando/entando-de-app
   

2. On a command line, cd into the entando-de-app you just cloned:

   cd entando-de-app
   

3. Build a docker image from the core app

   mvn clean package -Pwildfly -Pderby docker:build
   

4. View the images installed on your local docker instance

   docker images
   

   Look for

   entando/entando-de-app:latest
   

5. Create a repository on your docker repository to house your new application

6. Re-tag the image you just built with your repo

    docker tag entando/entando-de-app:latest <YOUR-USER>/<YOUR-REPO-NAME>:latest
   

7. Push the Image to your Repository

   docker push <YOUR-USER>/<YOUR-REPO-NAME>:latest
