DCR Virtual Classroom

Ever wonder how to set up a proper entry point for internet traffic to reach your cluster? Tomorrow, I’m breaking down the essential connection path:

The Setup:

Port-Forward for quick local tests.

NodePort for node-level access.

HAProxy as the External Load Balancer.

...all leading right to the doorstep of the Ingress Controller.

Stay tuned! 🚀

We started with POD IP ➝ then moved to Service IP ➝ from Service IP to Service Name (CoreDNS).

In the Service IP section, I briefly introduced NodePort.
So next, we’ll go step by step and understand why each exposure method exists:

• What is Port Forwarding and why do we use it?
• What is NodePort and why do we use it?
• What is an External Load Balancer and why do we need it?

And finally, we’ll reach the real game changer 🦖
👉 Ingress Controller what it is, why it exists, and how it simplifies everything.

Stay tuned 🚀

Hi all,

I saw this it was published just 2 days ago. A very small and fast LLM is now available that can run on mobile devices and supports NLP and function calling. This means that soon mobile phones may ship with built-in LLMs, enabling voice commands and direct function calling to perform actions automatically.

Example: i can say, Open WhatsApp and send hey dinesh bro I will be late , and the LLM will understand the intent and trigger the required functions.

Current drawback (Siri/Bixby): They rely on fixed commands, have limited understanding, and usually handle only one action at a time.

The model name is GEMMA FUNCTION you can check the demo in the given link : ai.google.dev/gemma/docs/functiongemma

Hi all,

I am planning to temporarily pause weekly video postings for the next two months. During this period, I will focus on recording as many topics as possible. Starting from March, I plan to release the pre-recorded videos daily so that the course can be completed much faster.

🧩 Kubernetes Beginner Question

We have a small problem with Pod IPs 👀

👉 Whenever a Pod restarts, its IP address changes.
Because of this, applications cannot rely directly on Pod IPs.

✅ To solve this, Kubernetes introduced Service IP (Stable IP).

🤔 But here’s the interesting question:

❓ If a Service is deleted and recreated, will we get the SAME Service IP or a NEW one?

🔍 Let’s find out with a demo in tomorrow’s video 🎥🔥

Stay tuned! 🚀


Remaining Topics:

- CoreDNS
- NodePort Issue
- HAProxy
- Ingress Controller
- Compute Quota
- Resource Quota
- LimitRange
- Secrets
- ConfigMap
- NetworkPolicies
- RBAC
- Volumes [both docker & k8's]
- DaemonSet
- HELM[basics]
- Probes
- Prometheus
- POD vs Container[Which is important for next course SERVICE MESH]
- INIT Containers
- Docker Compose
- Private Registry
- Metallb
- Multus

All for FREE & Don't ask me when this will be completed 😂😂😂. Once you know all these things no need to look back you will be pro in Kubernetes.
