![Build status](https://github.com/joonas-fi/hellohttp/workflows/Build/badge.svg)

A hello world HTTP server with Prometheus metrics.

When deploying, specify (service-level) ENV variable `METRICS_ENDPOINT=/metrics` to

optionally expose metrics automatically with

[promswarmconnect](https://github.com/joonas-fi/hellohttp).

Example

-------

```

$ docker service create \

  --name hellohttp \

  --env "METRICS_ENDPOINT=/metrics" \

  --network yourNetwork \

  --publish 8012:80 \

  "ghcr.io/joonas-fi/hellohttp:VERSION"

```

Replace VERSION with a tag from Docker Hub link from top of this document.

You can now access http://localhost:8012/

Metrics are at http://localhost:8012/metrics (look for `requests_served`).

If you're using promswarmconnect, `requests_served` should now be queryable from Prometheus.
