2 things to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
8 stars8 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

/stack — Generate a Swarm Stack File

Input examples

/stack .NET API + Angular + Postgres --replicas 3
/stack worker service --replicas 2 --with-db
/stack fullstack --with-proxy    (adds a Traefik front, see traefik-proxy-stack.yml)

Process

Detect the services and their dependency order.
For each service: base image (reuse docker-kit/docker-conventions.md for the Dockerfile side), deploy: stanza per swarm-conventions.md, healthcheck.
Sensitive values → reference an external: true secret, never an inline env var — see /secret.
Attach all services to a stack-scoped overlay network.
L1 approval → Write.

Mandatory rules

deploy.replicas explicit for every service — never rely on the Swarm default of 1
resources.limits + .reservations both set
update_config + rollback_config both set — a rollout with no rollback plan is incomplete
Secrets via docker secret — never plain env vars for passwords/keys/tokens
Stateful services (db, anything with local volume) get placement.constraints
No inline Ingress — routing by hostname needs a proxy front (--with-proxy), Swarm has no Ingress resource

Output

docker-stack.yml
.env.example              (placeholders only — real secrets are never written to a file the agent generates)
