Postgres and Redis containers with Docker Compose

Docker Compose facilitates spinning up containers for databases without installing the databases locally. This post covers the setup for Postgres and Redis images.

Prerequisites

• Docker Compose installed

Configuration

The following configuration spins up Postgres and Redis containers with UI tools (Pgweb and Redis Commander).

Connection strings for Postgres and Redis are redis://localhost:6379 and postgres://username:password@localhost:5435/database-name.

Pgweb and Redis Commander are available at http://localhost:8085 and http://localhost:8081 links.

# docker-compose.yml
version: '3.8'
services:
  postgres:
    image: postgres:alpine
    environment:
      POSTGRES_DB: database-name
      POSTGRES_PASSWORD: password
      POSTGRES_USER: username
    ports:
      - 5435:5432
    restart: on-failure:3
  pgweb:
    image: sosedoff/pgweb
    depends_on:
      - postgres
    environment:
      PGWEB_DATABASE_URL: postgres://username:password@postgres:5432/database-name?sslmode=disable
    ports:
      - 8085:8081
    restart: on-failure:3
  redis:
    image: redis:latest
    command: redis-server
    volumes:
      - redis:/var/lib/redis
      - redis-config:/usr/local/etc/redis/redis.conf
    ports:
      - 6379:6379
    networks:
      - redis-network
  redis-commander:
    image: rediscommander/redis-commander:latest
    environment:
      - REDIS_HOSTS=local:redis:6379
      - HTTP_USER=root
      - HTTP_PASSWORD=qwerty
    ports:
      - 8081:8081
    networks:
      - redis-network
    depends_on:
      - redis
volumes:
  redis:
  redis-config:
networks:
  redis-network:
    driver: bridge

Run the following command to spin up the containers.
