Noisebridge Infrastructure

This repo contains configuration and code to deploy Noisebridge infrastrucutre.

Code of Conduct

Noisebridge infrastructure members follow the Rack Code of Conduct

Security

Noisebridge infrastructure members protect the privacy and security of our systems and members.

  • Secrets should be checked in using ansible-vault.
  • The vault password should be kept safe.
  • Care needs to be taken when handling Issues and PRs to protect the privacy of members.

Reliability

Noisebridge infrastructure members keep services up and running.

  • Test changes as best as you can before pushing to production.
  • Improve monitoring as you go.
  • Think first, deploy once.
  • Rollback quickly when things fail.

Reproducibility

Noisebridge infrastructure members should ensure that changes are made in a way that is reproducibile for others.

  • All changes to infrastructure should be checked into this repo.
  • Changes should be made with Pull Requests so that they can be reviewed.
  • Think about making sure your changes are reasonably future-proof.

By documenting how systems are built in this repo, if a disk falis, a computer walks off, ansible can easily rebuild services and systems. This also helps a future systems spelunker who would like to know how a thing works and is set up.

Ansible

Much of the code here is the Noisebridge infrastucture Ansible configuration. Ansible is used to automatically deploy configuration to the various nodes (VMs and hardware in the space).

Submodules

This repo includes git submodules to vendor external source. You need to update them with this helper command.

./update-submodules.sh

Ansible runtime environment

Currently, this requires >= ansible 2.8.

Ansible is primarily distributed as a python3 package. So that we can consistently target the same ansible versions (which has knock-on effects, like what jinja2 templating filters are available), we also constrain the ansible version at the top of playbook documents with an assertion task.

Upstream instructions on installing Ansible

Deployment

Deploying the entire thing should be possible with just one command:

ansible-playbook site.yml

Usually, you will want to limit your deployment to specific host groups:

ansible-playbook site.yml --limit noisebridge_net

You can be even more specific, for example, this deploys only to the noisebridge_net roles tagged website:

ansible-playbook site.yml --limit noisebridge_net -t website

Ansible Vault

Some data is encrypted so that secrets (ie people's email addresses) aren't public. To edit files with secrets, first put the ansible vault password in a .vault-password file in the root directory of the git repo, then run:

ansible-vault edit path/to/secrets.yml

To get the vault password, check https://www.noisebridge.net/wiki/Accounts to see who has it.

Remote access to .noise

In order to deploy to machines remotely, you will need to configure a bastion bouncer.

In your ~/.ssh/config add the folowing.

Host *.noise
  User         YOU
  ProxyCommand ssh pegasus.noisebridge.net -W %h:%p

Updating Ansible Galaxy roles collections

Ansible uses collections to provide groups of roles. These are included inline in the /collections directory in this repo. The list of collections and versions are maintained in /requirements.yml.

To update the inline collection vendoring:

ansible-galaxy collection install -r requirements.yml --upgrade

To update the inline role vendoring, first update the version in requirements.yml then:

ansible-galaxy role install -r requirements.yml
