Internal Wiki Notifier

A service (read: a bash script) that runs in a Docker container and notifies a select Discord channel using webhooks of any updates to the Internal CompSoc Wiki.

Deployed automatically through GitHub CI and Watchtower. The CompSoc TechSec will have SSH access to the deployment VM to configure webhook URLs and API keys (for Wiki.js) through environment variables.

First Time Setup

For new local copies (e.g. new TechSec after a handover), clone this repository, and run make initialise. As a prerequisite, this will require you to have SSH access configured in ~/.ssh/config for [email protected]. The initialisisation will download any production keys to your computer if the service is already deployed and running. After this, edit as you like locally and follow steps in the Continuous Development section.

For new remote setups (e.g. deploying to a new VM or under a different service name), run the above initialisation step first. Then, create a new local .secrets/.env file if it does not exist yet, and specify the environment keys to pass to the Docker container. Then run make sync-secrets and make restart. Then follow the steps in Continus Development.

Continuous Development

During development, commit any changes to the code to Git and push to GitHub to trigger an automatic Docker image build and a notification to Watchtower on the production to VM. If there was a previous production instance, Watchtower will re-download the latest image and re-deploy with the latest image. This is all you need to update a deployment's code.

However, to update a deployment's environment variables (i.e. those in .secrets), you will need to manually sync them over via SSH because they are secrets! Not meant to be publicly embedded in Docker image builds.

There is a helper script within the makefile, so after any local changes to the secrets, run make restart to stop remote services if any are running, sync the secrets, and start the service.

Logs

To view production logs (prerequisite: SSH access), use make logs or make tail.
