Kubernetes Secrets

Create from file is easier kubectl create secret generic botsecrets --from-env-file=.env

• Edit secrets with kubectl edit secrets <uri>
• View secrets with kubectl get secret <uri> -o jsonpath='{.data}'

Run tests

Run without docker

Assuming you have exported ENV vars to your shell from .env you can now run tests with:

make test

Run with docker compose

Assuming you have filled in the .env file you can now run tests with:

make test-in-docker

Get it running one of three ways

Binary

• Apply k8s deployment to cluster kubectl apply -f k8s/k8s.yml
• Done

Docker Hub

For every bot update the docker image needs to be bumped so that Kubernetes can get the latest image.

• Build and tag image docker build -t jonwho/discord-bot:runbot-v{n} -f Dockerfile.runbot .

Where n is the bump number

• Push the image to Docker Hub docker push jonwho/discord-bot:runbot-v{n}
