This repository provides a setup to spin up multiple Docker instances using Docker Compose based on a user-defined configuration file. The solution includes scripts and configurations to dynamically generate and start the necessary Docker containers for each instance defined in the configuration file.

Features

Dynamic configuration - Easily specify multiple Docker instances in a YAML configuration file.
Automated setup - Scripts to automatically generate Docker Compose files and start the defined services.
Isolated environment - Each instance runs in its own Docker container, ensuring isolation and manageability.
Simple deployment - Utilize Docker Compose for streamlined setup and management of services.

Usage

1.‎‎‏‏‎ ‎Clone the repository

 git clone https://github.com/qasah/local-infrastructure.git

2.‎‎‏‏‎ Define your config.yaml file

3.‎‎‏‏‎ Set executable permission (if not already set)

 chmod +x .sh

4.‎‎‏‏‎ Run

 docker compose -f components.yaml up

Example of config.yaml

project: valhalla
components:
  postgres:
    image: postgres
    tag: 16-bullseye
    restart: always
    port: 5432
    instances:
      - name: authentication-service
        port: 5432
        values:
          - POSTGRES_USER=***
          - POSTGRES_PASSWORD=***
          - POSTGRES_DB=***
      - name: notification-service
        port: 5433
        values:
          - POSTGRES_USER=***
          - POSTGRES_PASSWORD=***
          - POSTGRES_DB=***
  redis:
    image: redis
    tag: 7.2-alpine
    restart: always
    port: 6379
    instances:
      - name: queue
        port: 6379
        values:
          - REDIS_PASSWORD=***
      - name: cache
        port: 6380
        values:
          - REDIS_PASSWORD=***
      - name: rate-limit
        port: 6381
        values:
          - REDIS_PASSWORD=***

Issues

• Volumes are currently not supported.
• If there's no config.yml file. After the process exits, a config.yml folder is automatically created - this is caused by the volume in the components.yaml file.
• Existing configurator container needs to be deleted before a new one can be launched.
