Ansible Collection - ls1intum.artemis

This collection contains all ansible roles necessary to deploy Artemis.

This is a work in progress repository - Please open issues if you encounter problems.

Installation

Installation via ansible-galaxy:

ansible-galaxy collection install ls1intum.artemis

Installation via git:

Manual install:

ansible-galaxy collection install git+https://github.com/ls1intum/artemis-ansible-collection.git,main

Install via requirements file:

Add the following to your ansible requirements:

collections:
  - name: https://github.com/ls1intum/artemis-ansible-collection.git
    type: git
    version: main # You can also specify a spcific version here!

Install dependencies

Ansible does not support role dependencies for collections - So you need to install the dependencies by hand :(.

The repository contains a requirements.yml file which contains all the external roles used in artemis. Please install these with ansible galaxy:

#This command will only work if you installed the collections to the default location!

ansible-galaxy install -r ~/.ansible/collections/ansible_collections/ls1intum/artemis/requirements.yml

Documentation

You can find the documentation for Artemis here. Each role includes a readme and default configuration. Consult these for more information.

Use the examples in the examples folder as starting point for your deployment (Warning: the examples are currently outdated and are being reworked)

Deployment Strategies

Artemis can be deployed in different ways. Depending on the use case the ansible configuration differs.

You can find examples for each configuration in the examples folder. Warning: the examples are currently outdated and are being reworked

Single Node installation

All Artemis components are deployed to a single host. This is the prefered deployment strategy for small installations or testing/evaluation purposes.

Multi Node installation (Cluster)

Artemis components are installed on different hosts. Currently the following components need to be set up for an Artemis cluster:

  • Artemis application servers (1..n - Also referred to as "Artemis node")
  • Reverse Proxy (1)
  • Message Broker (1)
  • JHipster registry (1)
  • Shared Storage Provider (1)
  • Database (1)

This setup allows to scale Artemis to support many concurrent users.

Version Control & Continuous Integration

Artemis relies on (external) services to handle version control and continuous integration. Currently three configurations are supported by Artemis:

  • Integrated Code Lifecycle
  • Gitlab, Jenkins
  • GitlabCI

The ansible configuration has to be adapted accordingly. Again, you can find examples for both in the examples folder. Warning: the examples are currently outdated and are being reworked

Test Servers

This collection also allows to provision test servers/clusters. To provision a test server or test cluster, set the

is_testserver: true

variable in your group_vars.

Tests

All roles have been tested on ubuntu 20.04 LTS

Ansible Development Setup

It is a good idea to install ansible and ansible-lint to a venv:

virtualenv venv
. venv/bin/activate.fish
pip3 install -r requirements.txt
