sixpack-docker

Docker image and orchestration for Sixpack A/B testing service.

Overview

This project provides:

• Dockerfile: Multi-purpose image for Sixpack API and Web (Python 2.7.18, pinned dependencies, Gunicorn).
• Docker Compose: Local stack with Sixpack API, Sixpack Web, and Redis.
• Kubernetes: Deployment and service manifests for API and Web under kube/.

Requirements

• Docker and Docker Compose (Compose V2)
• For Kubernetes: kubectl and cluster access

Docker Compose

Starting the stack

Build and start all services (API, Web, Redis):

docker compose up --build

• Sixpack API: http://localhost:5000
• Sixpack Web: http://localhost:5001
• Redis: internal only (port 6379)

Run in detached mode (background):

docker compose up --build -d

Stopping the stack

Stop and remove containers, networks, and optionally volumes:

docker compose down

To also remove volumes (e.g. Redis data):

docker compose down -v

Other useful commands

• View logs: docker compose logs -f
• Restart a service: docker compose restart sixpackapi or docker compose restart sixpackweb
• Rebuild after Dockerfile changes: docker compose up --build

Image details

• Base: python:2.7.18
• Sixpack: 2.0.2, installed with --no-deps; dependencies are pinned to avoid pulling yuicompressor from PyPI.
• Server: Gunicorn 19.3.0 with gevent workers (default CMD).
• Commands: sixpack (API) and sixpack-web (Web) are used in Compose and Kubernetes.

Environment variables

Variable	Description
SIXPACK_CONFIG_ENABLED	Enable Sixpack (e.g. true)
SIXPACK_CONFIG_REDIS_HOST	Redis host (e.g. redis in Compose)
SIXPACK_CONFIG_REDIS_PORT	Redis port (default 6379)
SIXPACK_CONFIG_REDIS_PREFIX	Redis key prefix (e.g. sixpack)
SIXPACK_CONFIG_CSRF_DISABLE	Disable CSRF (optional, used in Web in k8s)

Kubernetes

Manifests in kube/:

• sixpack-api-controller.yaml – Deployment for API (command: sixpack, containerPort: 5000)
• sixpack-web-controller.yaml – Deployment for Web (command: sixpack-web, containerPort: 5001)
• service-sixpack-api.yaml – Service for API (port 80 → container targetPort: 5000)
• service-sixpack-web.yaml – Service for Web (port 80 → container targetPort: 5001)

Deployments use image us.gcr.io/jusbrasil-155317/sixpack:v0.1 (Google Container Registry) and expect a Redis service (e.g. sixpack-redis-db).
