Creating and Using a Personal Homebrew Tap

Follow these steps to create a personal Homebrew tap and use it:

1. Create a new GitHub repository

The repository name should follow the format homebrew-<tap>.
For example, if you want to create a tap named mytap, the repository name should be homebrew-mytap.

2. Add formulae to the tap

In the repository, create a new file for each formula you want to add.
The file should be named <formula>.rb and contain the Ruby code for the formula.
For example, to add a formula named myformula, create a file named myformula.rb.

3. Tap the repository

On your local machine, use the brew tap command followed by your GitHub username and the tap name:
```
brew tap <username>/mytap
```

Replace <username> with your GitHub username.

4. Install formulae from the tap

You can now install formulae from your tap using the brew install command followed by the formula name: myformula

Replace myformula with the name of the formula you want to install.

Please replace <username>, mytap, and myformula with your actual GitHub username, tap name, and formula name respectively. Also, this is a very basic example. Depending on your needs, you might want to add more complex formulae to your tap.

K9s - CLI Management Advanced Usage

Uplift3r — Sun, 07 Jul 2024 19:12:34 +0000

Introduction

K9s for advanced usage, exploring, technical examples for experienced Kubernetes users.
provide by target-ops

Install K9s using Homebrew:

brew install k9s

Alternatively, download the latest binary from the K9s releases page and add it to your PATH.

1. Custom Resource Views

K9s allows you to create custom views for specific Kubernetes resources.\
Create a $HOME/.k9s/views.yml file:

k9s:
  views:
    v1/pods:
      columns:
        - NAME
        - READY
        - STATUS
        - RESTARTS
        - CPU
        - MEM
        - AGE
        - NODE

This configuration customizes the pod view to include CPU and memory usage.

2. Plugins

K9s supports plugins for extended functionality. Create a plugin in $HOME/.k9s/plugins.yml:

plugins:
  helm:
    shortCut: Ctrl-H
    description: Helm Charts
    scopes:
      - all
    command: kubectl
    background: false
    args:
      - get
      - helmreleases
      - --all-namespaces

This plugin allows quick access to Helm releases across all namespaces.

3. Resource Editing

built-in YAML editor for resources. To edit a resource:

Navigate to the resource
Press e to open the editor
Make changes and save

4. Port Forwarding

Easily set up port forwarding:

Navigate to a pod
Press Shift-F
Enter local and remote ports

Example:
CopyLocal Port: 8080
Remote Port: 80

This forwards local port 8080 to the pod's port 80.

5. Log Streaming and Filtering

Stream logs from multiple pods simultaneously:

Select pods using the space bar
Press l to view logs Apply filters using the / key:

error|warning

This filters logs to show only lines containing "error" or "warning".

7. CRD Management

Easily manage Custom Resource Definitions (CRDs):

Press :crd to list all CRDs
Navigate to a CRD and press enter to view instances

8. Context and Namespace Switching

Quickly switch between contexts and namespaces:

Press :ctx to list contexts Press :ns to list namespaces

9. Cluster Events Monitoring

Monitor cluster-wide events:

Press :events or ctrl-e
View real-time cluster events

Filter events: /NodeNotReady|FailedMount

10. Resource Utilization

View resource utilization across the cluster:

Press :pulses or ctrl-u
Monitor CPU, memory, and storage usage

11. YAML Diff

Compare resource YAML definitions:

Navigate to a resource
Press d to view YAML diff
Use j and k to navigate changes

This is useful for tracking changes over time or across environments.

Advanced Example: Automated Deployment Analysis

Let's create a K9s plugin that analyzes deployments and reports potential issues.

Create a script analyze_deployments.sh:

#!/bin/bash

kubectl get deployments -A -o json | jq -r '
  .items[] |
  select(.spec.replicas != .status.availableReplicas) |
  "\(.metadata.namespace),\(.metadata.name),\(.spec.replicas),\(.status.availableReplicas)"
' | column -t -s, -N "Namespace,Deployment,Desired,Available"

Add the plugin to $HOME/.k9s/plugins.yml:

plugins:
  analyze-deployments:
    shortCut: Ctrl-A
    description: Analyze Deployments
    scopes:
      - deployments
    command: /path/to/analyze_deployments.sh
    background: false

In K9s, press Ctrl-A to run the analysis

This plugin quickly identifies deployments where the desired state doesn't match the current state, helping troubleshoot scaling or health issues. Conclusion.

K9s offers a wealth of advanced features for managing Kubernetes clusters on macOS. By leveraging custom views, plugins, and built-in tools, you can significantly enhance your Kubernetes workflow. Experiment with these advanced techniques to streamline your cluster management and gain deeper insights into your Kubernetes environments.
