Kubernetes Port Forwarding Patterns 👇

You're inside a dev cluster, access to the network is restricted, and the service you just deployed is acting up.

There’s no LoadBalancer, no ingress controller in place, and opening up a port is not an option because the network team is either slow or says no.

This is where kubectl port-forward unblocks you.

Here I've simplified for your easy understanding.

Quick Linux tip:

Working with CSV files in the terminal?

You can make them readable by aligning columns neatly with column:

$ cat inventory.csv | column -t -s,

The -s, flag tells it to use commas as separators, and -t formats the output into a clean table.

Perfect for quick data inspection without opening a spreadsheet.

Part 1: What Are Linux Namespaces

On a Linux system, every process shares the same global view, the same process list, network interfaces, and filesystem view.

Namespaces change that. They let processes live in isolated “worlds,” each with its own network, process tree, and filesystem, all under the same kernel.

It’s how Linux creates the foundation for containers without running a full virtual machine.

In this series, we’ll take a look at each namespace, how it works, and how to experiment with them using standard Linux tools.

Quick Linux tip:

When you need to create several directories at once, you don’t have to do it one by one.

The mkdir command supports brace expansion, letting you create multiple nested directories in a single go.

$ mkdir -p ~/scripts/{site-01,site-02}/{backup,monitoring,network}

This instantly creates folders for two sites, each with its own backup, monitoring, and network directories.

A neat way to save time and keep your directory structure organized.

Quick Linux tip:

The diff command is a useful tool for finding differences between files in the Linux terminal. However, icdiff offers an even better side-by-side comparison with colorized output.

$ icdiff config-dev.ini config-prod.ini

The output will display both files side-by-side with any differences highlighted in red and green, making it easy to spot the difference.

Docker 101: Pass Environment Variables to Containers 🐳

Apps are often configured via env vars. However, if you set an env var in your current shell, it won't be passed to the container, because it runs in its own execution environment.

As a software engineer, it's very important to learn about Gall’s Law, which states that complex systems cannot be created successfully from scratch.

In reality, even large systems, such as Netflix, Google, or Facebook, have started small and built incrementally over the course of decades.

Error Handling & Debugging

What is Error Handling & Debugging?

→ Error Handling ensures that when something goes wrong, the system responds gracefully instead of crashing.
→ Debugging is the process of finding, understanding, and fixing those errors.

Error Handling Techniques

→ Try-Catch Blocks → Wrap risky code so errors can be caught and managed.
→ Validation → Check user input and data before processing.
→ Fallbacks → Provide defaults or backup actions when errors occur.
→ Logging → Record errors for later analysis.

Debugging Practices

→ Print/Log Statements → Quick checks using logs or console outputs.
→ Debugging Tools → Use IDE debuggers, breakpoints, and stack traces.
→ Monitoring Tools → Spot issues in real time through error logs and alerts.
→ Reproduce the Bug → Isolate conditions under which the bug occurs.

Common Error Types

→ Syntax Errors → Code written incorrectly (e.g., missing semicolon).
→ Runtime Errors → Errors that occur while the program is running (e.g., divide by zero).
→ Logical Errors → Code runs but gives wrong results (hardest to catch).

Analogy

→ Error Handling → Like airbags in a car—they don’t prevent accidents but reduce damage.
→ Debugging → Like a mechanic investigating why the car broke down and fixing it.

Tip:

→ Always validate inputs
→ Use meaningful error messages
→ Log errors with enough detail
→ Don’t expose sensitive system info in errors
→ Automate alerts for critical failures

For large datasets, using limit + offset doesn't always perform well, especially when the offset value is large.

Instead, you can use a cursor-based pagination where you filter by the order values.

There is a reason services like GitHub handle pagination this way!

Send HTTP Requests in C with libcurl

actually, sending a POST request in C is really easy using libcurl. Here's how:

- set the url: point to the endpoint of the api
- add json data: pass the data by using curl_easy_setopt
- set headers: include content-type: application/json for structured requests
- send the request: use curl_easy_perform for that

this is an example of sending jaon data to an api endpoint with custom headers.

[Milan Jovanović @mjovanovictech]

One of the most important distributed systems concepts:

→ Idempotency

It's also crucial when designing REST APIs.

You can repeat an idempotent operation multiple times without changing the system's state after the first API request.

This is especially important in distributed systems.

Network failures or timeouts can lead to repeated requests.

Your system should be able to handle transient errors like this.

Example flow for implementing idempotency:

1. The client generates a unique key for each operation and sends it in a custom header.

2. The server checks if it has seen this key before
- For a new key, process the request and store the result
- For a known key, return the stored result without reprocessing

How do you implement this in .NET?

Are you handling idempotency in your APIs?

DevOps official language has to be 'YAML'

- Helm uses YAML
- GitHub uses YAML
- Ansible uses YAML
- Argo CD uses YAML
- Kubernetes uses YAML
- Azure DevOps uses YAML
- Docker Compose uses YAML
and more ...

All the sophisticated toolsets you aspire to learn and adopt run on YAML.

Get that right first.
