Prerequisites

What is the first step to creating my own website?

Choose a domain name.

https://www.computate.org/enUS/course/001/001-choose-domain-name

For Red Hat employees, see Christopher Tate for details about a domain name you can use for development, or feel free to obtain your own for practice.

What can I do once I have purchased a domain name?

Obtain a valid TLS certificate for free, for security and credibility.

https://www.computate.org/enUS/course/001/008-how-to-obtain-free-tls-certificates

For Red Hat employees, see Christopher Tate for details about the TLS certificates you can use for development, or feel free to generate your own for practice.

Where can I host the project online?

Red Hat OpenShift Online is the very best open source cloud hosting available.

https://www.openshift.com/products/online/

For Red Hat employees, you can get permission from your manager to create a free OpenShift account to deploy to:

Installation

The installation of the project for both development and production in containers is completely automated with Ansible. Begin by installing both the ansible and python3 packages.

sudo yum install -y ansible python3 python3-pip
sudo pip3 install psycopg2

If psychopg2 does not install, run:

sudo pip3 install psycopg2-binary

Ansible on older operating systems.

If you have an older operating system that does not yet support python3, you may struggle to deploy the application on OpenShift in the cloud. The OpenShift Ansible modules seem to require python3 as the system library, so I recommend updating your operating system to something more recent, for example CentOS8 or RHEL8.

On older operating systems, to deploy the development applications you might want to configure ansible for python2.

To deploy to OpenShift, you will want to configure ansible to point to python3.

You might update your ansible configuration like this to make it work:

sudo vim /etc/ansible/ansible.cfg

[defaults]
interpreter_python=/usr/bin/python3

Your dependencies might be different on an older operating system.

sudo yum install -y ansible python python-pip
sudo pip install psycopg2

Ansible training.

For training on ansible and automation, I recommend the following Red Hat course. By completing the course and taking the exam, you can be a Red Hat Certified Specialist in Ansible Automation.

Development installation of southerncoalition.

Create an ansible inventory for development.

You will want to create your own directory to store your ansible inventories for both development and production in the cloud.

Create a directory for your ansible scripts.

sudo install -d -o $USER -g $USER /usr/local/src/southerncoalition-ansible

Create a directory for your development inventory.

install -d /usr/local/src/southerncoalition-ansible/inventories/$USER-localhost/host_vars/localhost

Create a hosts file for your development inventory.

echo 'localhost' > /usr/local/src/southerncoalition-ansible/inventories/$USER-localhost/hosts

echo "
[computate_org]
localhost

[computate_postgres]
localhost

[computate_zookeeper]
localhost

[computate_solr]
localhost

[computate_certbot]
localhost

[southerncoalition]
localhost

[southerncoalition_login_enUS]
localhost

[southerncoalition_refresh_enUS]
localhost

[southerncoalition_backup_enUS]
localhost

[southerncoalition_restore_enUS]
localhost
" > /usr/local/src/southerncoalition-ansible/inventories/$USER-localhost/hosts

Create an ansible vault for the application secrets.

The contents of the vault will contain the secrets needed to override any default values you want to change in the southerncoalition defaults defined here.

https://github.com/computate/computate/blob/master/ansible/roles/southerncoalition/defaults/main.yml

There are descriptions for each of the fields. There are several sections of fields, including:

• southerncoalition system defaults
• Ansible defaults
• Zookeeper defaults
• Solr defaults
• PostgreSQL defaults
• computate-medical global defaults
• southerncoalition US English defaults
• SMTP defaults
• OpenID Connect auth server defaults
• SSL/TLS defaults

To add the neccesary variables to your vault, run:

cp inventories/southerncoalition-local/host_vars/localhost/vault inventories/$USER-localhost/host_vars/localhost/vault

Edit the encrypted ansible vault with a password for the host secrets for your development inventory.

ansible-vault edit /usr/local/src/southerncoalition-ansible/inventories/$USER-localhost/host_vars/localhost/vault

In the ansiable vault file, replace:

• USERNAME: the username of your machine
• PASSWORD: the password of your machine

Also, make sure your machine allows ssh. If you are on a linux machine (Fedora):

yum install -y openssh-server
systemctl start sshd.service
systemctl enable sshd.service
ssh localhost (say yes to creating the fingerprint)
exit

Clone the computate project to run the ansible scripts.

Create a directory for the computate project containing the ansible scripts to run.

sudo install -d -o $USER -g $USER /usr/local/src/computate

Clone the computate project.

git clone https://github.com/computate-org/computate.git /usr/local/src/computate

Change to the computate ansible directory.

cd /usr/local/src/computate/ansible

Run the playbook to install a PostgreSQL server on your development computer.

ansible-playbook computate_postgres.yml -i /usr/local/src/southerncoalition-ansible/inventories/$USER-localhost/hosts --vault-id @prompt

Run the playbook to install a Zookeeper cluster manager on your development computer.

ansible-playbook computate_zookeeper.yml -i /usr/local/src/southerncoalition-ansible/inventories/$USER-localhost/hosts --vault-id @prompt

Run the playbook to install a Solr search engine on your development computer.

ansible-playbook computate_solr.yml -i /usr/local/src/southerncoalition-ansible/inventories/$USER-localhost/hosts --vault-id @prompt

Run the playbook to install the southerncoalition project for development.

ansible-playbook southerncoalition.yml -i /usr/local/src/southerncoalition-ansible/inventories/$USER-localhost/hosts --vault-id @prompt

If you are on an older operating system with an older version of ansible, you may run into the following error:

ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path.

The error appears to have been in '/usr/local/src/computate/ansible/roles/southerncoalition/tasks/main.yml': line 62, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

  become_user: "{{POSTGRES_BECOME_USER}}"
- name: Grant enUS user access to database
  ^ here

This means that the older version of ansible probably doesn't support the postgresql_pg_hba module and you will have to remove that task before running the ansible playbook successfully. You will need to configure the PostgreSQL hba configuration yourself in this situation.

Start the development project in English.
