Cube Orchestrator

This repo is me following along to the book Build an Orchestrator in Go by Tim Boring.

It's a simplistic implementation of an orchestrator, like Kubernetes, written in Go using Docker.

Setup

You'll need Go installed as well as Docker.

go mod install

Run

To run the service and API:

CUBE_WORKER_HOST=localhost \
CUBE_WORKER_PORT=5556 \
CUBE_MANAGER_HOST=localhost \
CUBE_MANAGER_PORT=5555 \
go run .

curl -s --request POST \
    --header 'Content-Type: application/json' \
    --data '{"ID":"266592cd-960d-4091-981c-8c25c44b1018","State":2,"Task":{"State":1,"ID":"266592cd-960d-4091-981c-8c25c44b1018","Name":"test-chapter-5-1","Image":"timboring/echo-server:latest"}}' \
