This Repository Contains a Docker Compose Setup that creates multiple instance ready to use with unique Name, And Auto-Incremented ports numbers.
The purpose of this project is to simulate a multi-node server environment for testing software that manages and configures remote servers. This setup is particularly useful for developers and testers who need to validate software behavior in a distributed system.
Follow these steps to set up and use the multi-node server testing environment:
- Docker
- sudo apt install apt-transport-https ca-certificates curl software-properties-common
- curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
- sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable"
- sudo apt update && sudo apt install docker-ce
- sudo usermod -aG docker ${USER} && su - ${USER}
- sudo service docker start
- docker ps
- Docker Compose
- sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o ~/bin/docker-compose
- sudo chmod +x ~/bin/docker-compose
- docker-compose --version
-
Clone This Reposetory
git clone https://github.com/Pradipbabar/MultiNodeTestLab.git cd MultiNodeTestLab -
Generate SSH Key Pair:
ssh-keygen -t rsa -b 4096
-
Update dockerfile and docker-compose.yml file accordingly
-
Build and Start the Container
docker-compose up -d
-
Acess individual Containers
docker exec -it <conatiner name> bash
ssh -i <private key> -p <port-number> root@localhost
Use this setup to test software that interacts with multiple servers in a distributed environment. Validate your software's behavior in various network conditions.
Similar to tools like Ansible, Chef, and Puppet, use this setup to validate your own configuration management scripts or tools.
- The docker-compose.yml file defines the multi-node testing environment.
- Each node is isolated in its own Docker container.
- Modify the nodes/ directory to configure each node's software and services
