Super simple orchestration for stateless HTTP containers. This is a personal project I developed in an attempt to understand how a container orchestrator like Nomad/k8s would work under-the-hood.
Metis uses Traefik for load balancing between services (configuration can be checked in the docker-compose.yml).
It is currently being used to host https://oisinaylward.me across multiple nodes.
There is a HTTP header passed around containing a token. It was not built with security in mind - do not use somewhere where security is important.
Configuration is currently done entirely in the controller. It is entirely static - dynamic configuration is not yet possible. To change configuration, it requires bringing down the controller.
{
"name": "webserver",
"configuration": {
"image": "nginx",
"count": 2,
"container_port": 80,
"host": "webserver.localhost"
}
}
{
"address": "host.docker.internal",
"labels": [
"host-system"
],
"api_port": 6060
}
Dockerfiles can be found in the docker directory for both the controller & agent. Check docker-compose.yml for a sample single-node deployment.
