ispconfig3

Ansible Role: Installs and customizes ISPConfig 3 on Ubuntu Bionic

The inoxio.ispconfig3 role will help you to install ISPConfig on your Ubuntu 18.04 machine. It follows the instructions of the howtoforge.com tutorial and allows customizations which will be explained in the following segments. It also implements Molecule as a test environment and contains a few tips if you want use Molecule for yourself.

Requirements

  • Machine with Ubuntu 18.04

Dependencies

  • oefenweb.apt

Role Variables

Mail, PHPMyAdmin and Roundcube will set mostly the admin passwords of the named application. Mail itself will also need an email with which it can send mails to.

ISPConfig is here the most important part, it contains a lot of different variables. Most of them can be translated into the autoinstall.php from ISPConfig. It is also important to notice that the mysql_root_password will be used for the setup of the MariaDB module.

Playbook variables: The following variables are required in the playbook (except the passwords, that will be generated if left out). There are checks that verify that these variables are stated in the playbook. The default variables can be overwritten in the playbook.

Mail: This will set all needed variables to setup a new mailing list. It will automatically create a mailing list with the given Parameters.

  • mail_admin_email: Mail which will send/receive updates from Mailman.

  • mail_admin_password: (Optional) Password for Mailman admin. If no password is set a password will be generated and printed at the end of role execution.

  • mail_base_domain: Base domain for Mailman.

  • phpmyadmin_hostname: Base domain for phpmyadmin.

  • roundcube_admin_password: (Optional) Password for Admin Login in Roundcube. If no password is set a password will be created and printed at the end of role execution.

ispconfig: This contains the most configurations for your ISPConfig setup. Please have a look at the example provided by ISPConfig itself. You can find it here.

  • ispconfig_admin_password: (Optional) Password for the ISPConfig Admin Login. If no password is set a password will be generated and printed at the end of role execution.

  • ispconfig_mysql_root_password: (Optional) Password of the root user, please choose a secure one. Even if your database isn't exposed. If no password is set a password will be generated and printed at the end of role execution.

  • ispconfig_mysql_ispconfig_password: (Optional) Login for MySQL. If no password is set a password will be generated and printed at the end of role execution.

  • ispconfig_mysql_master_root_password: (Optional) Password for the root user of the master data. If no password is set a password will be generated and printed at the end of role execution.

  • ispconfig_hostname: Name of the ISPConfig host.

Quota

The list quota_mounts in defaults/main.yml contains all directories that will be edited in the fstab file to enable quota on them. If the list is empty quota will not be enabled. You can overwrite this list by adding the quota variable in the playbook (See section "Role Variables"). If the kernel on your machine does not contain the quota modules, you have to keep the list empty. This is the case for AWS machines that use the linux-aws kernel.

Multiple PHP versions

You can specify multiple PHP versions in vars/main.yml, that will be installed.

Example Playbook

This shows an example how you could configure your playbook.

- role: inoxio.ispconfig3
  mail_admin_email: [email protected]
  mail_base_domain: your-company.com
  ispconfig_hostname: ispconfig.your-company.com
  roundcube_hostname: mail.your-company.de
 

Everything else mentioned in role variables can be found in the defaults/main.yml.
All settings for the ISPConfig role are taken from the config file for the Apache2 setup. See this link for more information. You can find example settings under autoinstall.php for ISPConfig.

Start as VM and run tests with Molecule

Everything here is taken from https://Molecule.readthedocs.io/en/latest/. It's convenient to have everything in one place.

This will help you to run Ansible roles on a real virtual machine without caring about the state of the VM.

To start the role and run the test environment you will require Molecule. The following will explain how to setup everything and run the tests.

  1. Install virtualenv
    • Install virtualenv sudo apt install virtualenv
    • Create virtualenv inside your folder virtualenv --no-site-packages .venv This will contain all installed packages. This is the cleanest way to prevent your system from package cluttering.
  2. Start virtualenv
    • You will run this command every time you restart your console, or enter a new session.
    • source .venv/bin/activate
  3. Install the Molecule package
    • pip3 install Molecule ansible
    • You will need to install the Python API for your driver which you will use, in the case of this role it will be Vagrant.
    • Run this command if you see the (.venv) at the beginning of your console line.
    • pip install python-vagrant

These are the requirements you have to fulfill before starting Molecule. In the following it will be explained how you can setup roles for testing.

Run Test

Running tests is fairly easy, just go into your venv as seen in step 2 above and run:

Molecule test

This will automatically setup your driver (Docker or Vagrant in most cases) and run different test scenarios such as idempotence tests or your own written tests which can test all kind of things.

New Role

Molecule init role -r new-role -d vagrant

This will initialize a new Vagrant role with the name new-role and it will contain the standard setup for Vagrant. As alternative you can set your driver to Docker or other supported methods of virtualization.

Upgrade Molecule

Note: Molecule is relatively new so there will be updates, that is why it is recommended to run this from time to time.

pip install --upgrade Molecule

Example Molecule and Playbook

Here you are going to see an example how the Molecule.yml and the Playbook.yml is structured for this test scenario.

Molecule.yml

---
dependency:
  name: galaxy
driver:
  name: vagrant
  provider:
    name: virtualbox
lint:
  name: yamllint
platforms:
  - name: instance
    box: ubuntu/bionic64
    instance_raw_config_args:
      - "vm.hostname = 'web.my.net'"
    memory: 4096
provisioner:
  name: ansible
  lint:
    name: ansible-lint
    enabled: false
scenario:
  name: default
  test_sequence:
    # - lint
    - destroy
    # - dependency
    - syntax
    - create
    - prepare
    - converge
    - idempotence
    # - side_effect
    - verify
    - destroy
verifier:
  name: testinfra
  lint:
    name: flake8
    

Here you can see the used Molecule.yml for this project you can see the used driver and its settings, such as memory. Important Note: It was required for a task in the role to set the hostname so you can see that it is set with the help of instance_raw_config_args. You can use different boxes directly from Vagrant or load them from a link. For this type of change please consult the documentation of Molecule.

If you take a look at the Playbook.yml you will see it is similar to the normal role call but the name. See the full example below in the example playbook.

Playbook.yml

---
- name: Converge
  hosts: all
  roles:
     - role: inoxio.ispconfig3
         ***
         ***

Molecule

This section will contain a conclusion about Molecule because this was the first setup of it.

The first run with Molecule was with Docker as the driver. With this used method there were roadblocks really fast. Because of the nature of Docker and the complexity of this role. This started with services which aren't loaded inside a container and went on to PID which are different. So we had come to the conclusion that it isn't pleasant to adapt your code to your testing framework.

This left the choice of using Vagrant as the driver. This will help us with the problem of no full existing virtual environment and running everything smoothly.

This setup went without any major problems and tested all the wanted keypoints.

If you want so include Molecule in your role please follow this little list:

  • Make sure you start with a blank slate and create your role in Molecule so you can test it every now and then
  • If you want to use Docker make sure your role isn't too complex and you don't have to adapt your role to the Docker
