Project-Tyrann 👩‍⚖️

Bully Leader Election Algorithm implementation in Docker. Using this 🔗 page as an example of the bully algorithm.

Elements of the project

Server 🗄

The server is the one that can be leader or follower at some point in the architecture, so it has both functionalities built in.

Checklist 📋

• Create the server in Typescript or other language.
• Generate the REST enpoints for the server, that should look something like this.
  • Request GET: /status

    // response body 📤
    // OK
    {
      "response": 200
    }

  • Request POST: /election

    // response body 📤
    // OK, and will takeover from here.
    {
      "response": 200 
    }

  • Request PUT: /newLeaderPort

    // request body 📥
    // I'm the new leader, you should listen to this port.
    {
      "newLeaderPort": 123456
    }

  • Request GET: /leaderPort

    // response body 📤
    // This is the current leader of the system.
    {
      "leaderPort": 654321
    }

  • Request GET: /electionStatus

    // response body 📤
    // An election is not ongoing yet.
    {
      "electionStatus": false
    }

• Request the list of all of the current running servers in Docker to the Coordinator.
• Make two servers communicate with each other.
• The two servers should be sending /status requests every 3 or 10 seconds to the one that is the leader.
• If the leader fails to make a response, a new election is made by the server who detected the failure.
• The server should know which other nodes are more important than him.

Improvement 🎉

• May two or three requests be made as a Websocket, for it to be as realtime.

Dashboard 🖥 / Coordinator 👩‍🍳

This dashboard should be able to see the status of all of the servers in the system and their statuses and also has a little bit of functionality with the group of servers.

Checklist 📋

• Send the list of running servers currently in Docker to a server that has started and it does the GET request.
• Show all of the servers in the system.
• Get all of the statuses of the servers in the system.
• Get the status of the leader of each server in the system.
• Get the status of the election of each server in the system.

Improvement 🎉

• Try to make it this time in Svelte 🔗 for simplicity of build and stuff...
• Show how the election is being made.
