⁠23CSE528 NoSQL Database using MongoDB - Labs 7 to 10

Student: M Nagasai Girisharan | Roll no: 24BTRCL114 | Class: 5 AIML-B Submission: Exercise 10 - Transactions, Atomicity, Durability and Journaling

One image that contains all four labs and a website for them (Kavach CTI). MongoDB itself comes from the official mongo:7.0 image in the compose file.

⁠What is inside

⁠Lab dependency rule

Starting a lab starts the labs below it first: Lab 10 needs Lab 9 needs Lab 8 needs Lab 7 So starting Lab 10 runs Lab 7, then 8, then 9, then 10.

⁠How to run (only Docker Desktop is needed)

docker run --rm sharan10860/nosql-lab10 compose > docker-compose.yml
docker compose up -d lab10

Wait 3 to 5 minutes, then open http://localhost:8000/#/labs⁠

⁠Pages on the website

• Lab control centre - chain 7 -> 8 -> 9 -> 10, live output, status
• Replica set lab 8 - live members, verify replication, step down the primary
• Write concern lab 9 - live benchmark of w:1, w:majority and w:all
• Transactions lab 10 - bank transfer, rollback, conflict and retry demo, concurrent reservations, throughput chart

⁠Run Lab 10 on the command line

docker compose exec lab10 lab10 all     # everything + PDF report
docker compose exec lab10 lab10 10.1    # only Lab 10.1
docker compose exec lab10 lab10 10.2    # only Lab 10.2
docker compose exec lab10 lab10 bench   # throughput test

⁠Stop and clean up

docker compose down        # stop
docker compose down -v     # stop and delete the data

⁠Notes

• Ports used: 8000 (website), 27017, 27018, 27019 (MongoDB).
• Transactions need a replica set, so this stack runs 3 MongoDB servers.
• Tags: latest (works on Intel and Apple Silicon).
