Postgres and Redis containers with Docker Compose

Published February 26, 2023Last updated February 4, 20242 min read

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

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
