Advent of Code 2024

This year's advent of code is being solved in Go as a series of microservices running in a Kubernetes cluster (or docker-compose if you prefer). The Kubernetes solution is deployed using Helm and implements service discovery using services and ingress resources. The docker-compose solution also has a form of service discovery using traefik. Both of these will listen on port 80 and expose the individual services with the prefix /dayX.

Run the project

The project can be run either with Kubernetes (using minikube) or with docker-compose. Whichever option you choose, call ./client.sh -file INPUT_FILE -day DAY -part PART to run the solution.

If you don't want to use the client, curl is also an option: curl -X POST --data-binary @INPUT_FILE http://localhost/DAY/PART

Auto-fetch puzzle input

If you copy the file ./client-env.sh.example to ./client-env.sh and fill in your session token, the client (when running ./client.sh) can auto-fetch your puzzle input. You can then run the client as only ./client.sh -day DAY -part PART.

Running in Kubernetes

• Install minikube and run ./k8s/start-minikube.sh to create the aoc2024 cluster.
• Then run ./k8s/build.sh all to build all the docker images, making them available within minikube.
• Then run ./k8s/helm-install.sh to install or upgrade the Helm chart.

When changing a solution the image needs to be rebuilt, since helm has no logic to build the images for us. Run ./k8s/build.sh dayX to rebuild a single day, then rerun ./k8s/helm-install.sh to reinstall the Helm chart (which will recreate all deployments).

Running with docker-compose

Just run docker-compose up and it will run all services as well as the traefik gateway. If the watch feature of docker-compose is enabled, the services will be automatically rebuilt and redeployed ever time the common module or their own solutions/dayX module is updated.
