Project Description

• The project aims to deploy a web application using Docker Swarm, a container orchestration tool that allows for easy management and scaling of containerized applications.

• The project will utilize Docker Swarm's production-ready features such as load balancing, rolling updates, and service discovery to ensure high availability and reliability of the web application.

• The project will involve creating a Dockerfile to package the application into a container and then deploying it onto a Swarm cluster.

• The Swarm cluster will be configured to provide automated failover, load balancing, and horizontal scaling to the application.

  The goal of the project is to demonstrate the benefits of Docker Swarm for deploying and managing containerized applications in production environments.

prerequisite:

• EC2 instances(2 to 3 instances) - Swarm Manager and Swarm worker(we can increase no. of workers as much as we want) and allow port 8000 and 2377

  

  

• Docker is installed in all the instances.

  

Steps

1. run sudo Docker swarm init in Swarm Server

   

2. Paste the command in all worker server

   

3. To check the node is connected

   run sudo docker node ls

   

4. run the command to create a service

    sudo docker service create --name django-app-service --replicas 3 --publish 8001:8001 trainwithshubham/react-django-app:latest
   

   

5. now run sudo docker service ls

   

   

6. Now, just visit public_ip_addr of any node at port 8001

   

7. To detach any worker from the master just run sudo docker swarm leave on the worker server

   

   you can see it on the master server as a node is down

   

   Done!!💜
