Prerequisites

As this is a JHipster module, we expect you have JHipster and its related tools already installed:

• Installing JHipster

You have to install Docker and Docker Compose:

• Docker
• Docker Compose

To use Automated build, you have to create an account at:

• https://hub.docker.com/

Installation

With Yarn

To install this module:

yarn global add generator-jhipster-docker

To update this module:

yarn global upgrade generator-jhipster-docker

With NPM

To install this module:

npm install -g generator-jhipster-docker

To update this module:

npm update -g generator-jhipster-docker

Usage

To run the module on a JHipster generated application:

yo jhipster-docker

You can use this command to generate the Dockerfile for Automated build:

yo jhipster-docker default

To force the generator:

yo jhipster-docker default --force

1 - Automated build at the Docker Hub

1.1 - Description

When using the option Dockerfile for Automated build, Docker Hub will build a Docker image everytime you commit to your repository.

1.2 - Generate the files

• Launch : yo jhipster-docker
• Select the option : Dockerfile for Automated build at https://hub.docker.com/

1.3 - Set your Docker Hub project

At GitHub

• Go to Settings > Integrations & services
• Add service and select Docker
• Click [x] active
• Click on update service
• Back to Integration & services, Docker must be :white_check_mark: Docker

At Docker Hub

• Go to https://hub.docker.com/r/YOUR_DOCKER_ID/ (replace YOUR_DOCKER_ID by yours)
• Menu Create
  • Select Create Automated Build
  • Select the repository of your project
  • Put a description, then click on create

• Go to Build Settings
  • Choose your branch or let master by default
  • Put this Dockerfile location: /
  • Click on Save Changes

• Return to this project: git commit and push these changes!
• Go to Build details: it should be a new line with Building

2 - Local SMTP Server

The project djfarrelly/maildev is a simple way to test your project’s generated emails during development with an easy to use web interface.

You can launch:

docker-compose -f src/main/docker/smtp.yml up -d

You can access to it: http://localhost:1080

3 - NGinx as proxy server

See the official documentation

Follow these steps:

• Start your local backend server or use an existing one. You can start more than 1 backend server.
• Edit src/main/docker/nginx/nginx.conf, depending on the 1st step
• Start NGinx:

docker-compose -f src/main/docker/nginx.yml up -d

Note: The use of network_mode: 'host' in nginx.yml may not work for Windows or MacOS. Simply comment it and replace localhost in src/main/docker/nginx/nginx.conf file. Your container (from inside) must access to the application.

You can access to it: http://localhost or http://localhost:8000
