Multi-Service Application

This project is part of roadmap.sh DevOps projects.

---

This project simulates a real-world, production-like environment using Docker. It includes a multi-service setup with best practices like custom base images, multi-stage builds, Docker secrets, persistent volumes, health checks, optimized Dockerfiles, logging, and more.

The service i maked is simplate Note taking app.

Getting Started

git clone https://github.com/cilginc/multiservice-docker.git
cd multiservice-docker

2. Run the Docker Compose file

docker compose up -d --build

Accessing Grafana

1. Simply go to http://localhost:3000/grafana.

• User: admin
• Password: admin

2. Now go to Drilldown -> Logs. Now you can see all the log files.

Using CD with Github Actions

1. You need to manage Github Secrets first:

• REMOTE_HOST:IP of the server
• REMOTE_USER: User of the server
• SSH_KEY: Your private SSH key
• SSH_PORT: Your SSH port
• REMOTE_PATH: Remote path of directory you want such as /home/user/deploy

2. Don't Forget to change workflow permissions to read and write.

• This step is required for adding containers to GHCR.
• Now Github Actions will automaticly deploy your project after push.
