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.
