Spacelift Prometheus Exporter

This repository contains a Prometheus exporter for exporting metrics from your Spacelift account.

Quick Start

The Spacelift exporter is provided as a statically linked Go binary and a Docker container. You can find the latest release here. The Docker container is available from our public container registry: public.ecr.aws/spacelift/promex.

Authentication

The exporter uses Spacelift API keys to authenticate, and also needs to know your Spacelift account API endpoint. Your API endpoint is in the format https://<account>.app.spacelift.io, for example https://my-account.app.spacelift.io.

NOTE: the API key you use must be an Admin key because some of the API fields used for the metrics require administrative access.

Running via the Binary

Download the exporter binary from our releases page, make sure it's added to your PATH, and then use the spacelift-promex serve command to run the exporter binary:

spacelift-promex serve --api-endpoint "https://<account>.app.spacelift.io" --api-key-id "<API Key ID>" --api-key-secret "<API Key Secret>"

Running via Docker

Use the following command to run the exporter via Docker:

docker run -it --rm -p 9953:9953 -e "SPACELIFT_PROMEX_API_ENDPOINT=https://<account>.app.spacelift.io" \
  -e "SPACELIFT_PROMEX_API_KEY_ID=<API Key ID>" \
  -e "SPACELIFT_PROMEX_API_KEY_SECRET=<API Key Secret>" \
  public.ecr.aws/spacelift/promex

Running in Kubernetes

You can use the following Deployment definition to run the exporter:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: spacelift-promex
  labels:
    app: spacelift-promex
spec:
  replicas: 1
  selector:
    matchLabels:
      app: spacelift-promex
  template:
    metadata:
      labels:
        app: spacelift-promex
    spec:
      containers:
        - name: spacelift-promex
          image: public.ecr.aws/spacelift/promex:latest
          ports:
            - name: metrics
              containerPort: 9953
          readinessProbe:
            httpGet:
              path: /health
              port: metrics
            periodSeconds: 5
          env:
            - name: "SPACELIFT_PROMEX_API_ENDPOINT"
              value: "" # Add your endpoint here
            - name: "SPACELIFT_PROMEX_API_KEY_ID"
              value: "" # Add your API key here
            - name: "SPACELIFT_PROMEX_API_KEY_SECRET"
              value: "" # Add your secret here
            - name: "SPACELIFT_PROMEX_LISTEN_ADDRESS"
              value: ":9953"

To use the example deployment, make sure you fill in the API endpoint, API Key ID and API Key Secret, as explained in the comments. For a production deployment we would recommend making use of Kubernetes secrets rather than embedding the API key values directly.

Port Number

By default the exporter listens on port 9953. To change this use the --listen-address flag or the SPACELIFT_PROMEX_LISTEN_ADDRESS environment variable:

spacelift-promex serve --listen-address ":9999" --api-endpoint "https://<account>.app.spacelift.io" --api-key-id "<API Key ID>" --api-key-secret "<API Key Secret>"
