Deploying Open Food Network

These are Ansible playbooks (scripts) for managing an Open Food Network app server. This is not for your local development environment. Head to the OFN getting started guide to run the OFN locally.

Documentation

See the wiki for more information, including: additional setup, configuring, provisioning and deployment.

For deploying OFN versions below v4.x.x, please use the ofn-v3 branch of this repo.

Playbooks

These playbooks will install the Open Food Network app onto a server running an apt-compatible OS like Debian or Ubuntu. It has currently been tested on Ubuntu 16.04, 18.04 and 20.04 (64 bit) on AWS, DigitalOcean and Scaleway cloud servers.

The playbooks take information from the inventory. Make sure that your host's information is up to date before running a playbook (see host_vars/ and secrets).

These are the main playbooks (found under playbooks/). See inside each for more details. They can be executed together with site.yml:

• setup.yml - Use a root login to ensure python is installed and create a default user (defined in inventory/group_vars/all.yml) on the server for installation (mandatory the first time you provision a server).
• provision.yml - Install and configure all required software on the server (requires secrets, see below).
• deploy.yml - Deploy OFN to the server by copying a git repo to the server and using ruby/rake/rails tasks to configure and migrate.

Other playbooks include:

• backup.yml - Backup database and image files on the server to the local machine.
• rollback.yml - Rollback the database and codebase to the previous version.
• db_transfer.yml - Transfer the database directly from one host to another (see Refreshing a staging server)

You may want to use the ansible option "checkrun" to do a dry-run of the playbooks. With this option, Ansible will run the playbooks, but not actually make changes on the server.

Setup

• Fork the ofn-install repository.
• Clone the forked copy:

  git clone https://github.com/<your-namespace>/ofn-install.git
  

Python

It's recommended you set up your Python environment using Pyenv.

• Install and configure pyenv
• Install and configure pyenv-virtualenv
• Install the required Python version:

  $ pyenv install 3.8.2
  

• Create the virtualenv:

  $ pyenv virtualenv 3.8.2 ofn-install
  

Dependencies

You will need to install Ansible, alongside other dependencies, on your machine to run the playbooks. You can do so with:

pip install -r requirements.txt

Ansible Galaxy Roles

Some playbooks require third-party roles, which are specified in bin/requirements.yml. You can install with the included script:

$ bin/setup

Secrets

Some tasks require host-specific secrets, and will show an error if they haven't been provided. These can change from time to time, so always ensure you have the latest before provisioning.

Secrets can be provided with a parameter like so:

ansible-playbook playbooks/provision.yml --limit=au_staging -e "@../ofn-secrets/au_staging/secrets.yml" --ask-vault-pass

If you have access to the ofn-secrets repository, you can fetch them with the fetch_secrets.yml playbook. The secrets for each host will be loaded into the relevant directory in inventory/host_vars/, then you can go ahead and provision. See the readme for more tips on setup.

ansible-playbook playbooks/fetch_secrets.yml && ansible-playbook playbooks/provision.yml

Code quality

Run the ansible-lint checks using:

ansible-lint site.yml --exclude=community

This is also run in CI.

Security

This repository doesn't manage additional security configuration. The private repository ofn-security is used for servers managed by the OFN team.
