Custom Discord Bots powering the KlimaDAO community.
This is a monorepo containing multiple bots.
src/
- each folder corresponds to a specific bot
Each bot requires a separate application to be defined in the Discord Developer Portal. For each, do the following:
- Access the Discord developer portal: https://discord.com/developers/applications
- Create a new application: enter in the name of the bot (e.g. next-rebase)
- Create a bot: Click on "bot" in the sidebar and define a bot with the corresponding username.
- Check the "presence" and "server members" intents.
- Authorise the bot:
- Click on OAuth2 -> URL Generator in the sidebar.
- Select the "bot" scope.
- Copy the generated URL and open it.
- Select your server from the list and click on "Authorize". (You'll know that this has worked, as the bot user will appear in your Discord server.)
- Obtain the token for the bot: Settings -> Bot -> Token -> Copy
This project requires some API keys to run. When developing locally, you can create your own API keys from the following services:
- Infura: create a new project - https://infura.io/dashboard
- Note that you need to enable the Polygon add-on: https://infura.io/payment?chosenAddon=ethereum_polygon_addon
- PolygonScan: create an account - https://polygonscan.com/myapikey
- Discord webhook URL: create a personal server, channel settings -> integrations, create webhook
The bots are hosted on Digital Ocean App Platform under a single app. Upon any commit to the main
or staging
branches, the bots are deployed automatically.
Before this, the app must be created. It can be done through the DigitalOcean App Platform web interface, or through the make create
command.
Deployment follows this process:
- A Docker image is built and pushed to DOCR using the
Dockerfile
.- Note: This Docker image contains the source code to the bots. Do NOT include any confidential or proprietary information in the repository or build artifacts.
- The app is deployed to Digital Ocean, using the built Docker image as the basis.
To deploy manually, run:
DIGITALOCEAN_APP_ID=<INSERT ID> DIGITALOCEAN_ACCESS_TOKEN=<INSERT TOKEN> make deploy
The following environment variables must be defined in GitHub Actions:
DIGITALOCEAN_ACCESS_TOKEN
- Generate a personal access token at the following URL: https://cloud.digitalocean.com/account/api/tokens
DIGITALOCEAN_APP_NAME
DIGITALOCEAN_APP_ID
- In the Digital Ocean web interface, go to project -> apps, and copy the ID from the URL, e.g.
SOME-222-random-string
in https://cloud.digitalocean.com/apps/SOME-222-random-string/settings
- In the Digital Ocean web interface, go to project -> apps, and copy the ID from the URL, e.g.
DIGITALOCEAN_CONTAINER_REPO
- Name of the Docker image registry hosted by Digital Ocean. It will be the name listed on this page: https://cloud.digitalocean.com/registry
These variables must also be defined, and will be used to replace variables in the app-spec.yml file:
POLYGONSCAN_API_KEY
WEB3_INFURA_PROJECT_ID
DISCORD_BOT_TOKEN_REBASE
DISCORD_BOT_WEBHOOK_REBASE
DISCORD_BOT_TOKEN_KLIMA_PRICE
DISCORD_BOT_TOKEN_BCT_PRICE
DISCORD_BOT_TOKEN_MCO2_PRICE
DISCORD_BOT_TOKEN_STAKING_REWARDS
The above environment variables are used in the Digital Ocean App Platform environment. They are injected into the app-spec.yml
file for the following reasons:
- It is cumbersome to include the secret in the configuration file, deploy it and then copy/paste the encrypted value into the file again.
- Updating secrets becomes cumbersome as well.
Instead, it is much easier to define and rotate secrets through the GitHub Actions secrets. We use the envsubst
tool to achieve this.
Each Docker image is tagged with the GitHub commit SHA, which prevents parallel deployments (main
and staging
) from clobbering each other.
In order for parallel deployments to work, however, the following must be implemented:
- Define the "default" (non-production) environment variables for the GitHub repository. This ensures that any new branches will use non-production variables by default.
- Create an environment called "main" and define any variables that differ from the default variables. At a minimum, this should include:
DIGITALOCEAN_APP_ID
(or else different branches will be the same DigitalOcean app and clobber each other).- All of the
DISCORD_BOT_*
tokens (or else those bots will be clobbered).
