Implementing Kubernetes Jobs with NestJS and nest-commander: A Practical Guide (Ex. implementation with Ticketmaster)

The nest-commander package allows for crafting CLI applications with NestJS structure and flair.
The nestjs-job-commander repository demonstrates setting up a job processing system in Kubernetes using NestJS and nest-commander.
The repository includes apps, shared libraries, Kubernetes configuration files, Dockerfile, and environment variables configuration.
The CLI Enricher is built using NestJS and nest-commander, defining AppModule, main command, and subCommands.
The TicketMasterEventRefreshCommand within CLI Enricher fetches events from Ticket Master API and stores them.
Running the job outside Kubernetes involves using 'nest start' command with appropriate setup.
To run the job inside Kubernetes, steps include building a Docker image, setting environment variables, and creating Kubernetes config maps.
A cronjob.yaml file helps create a job inside Kubernetes, with scheduled execution of commands.
With NestJS Commander and Kubernetes, CLI applications can be efficiently built and deployed for job management.

How to Create Kubernetes(K8s) Cluster Home Lab using Ubuntu Server 24.04

To create a Kubernetes cluster home lab using Ubuntu Server 24.04, set up two nodes - a master node (kb1) and a worker node (kb2) with specific configurations.
Configure the nodes by changing the hostname, updating the host file for network communication, disabling swap, and loading kernel modules.
Install Containerd on all nodes to manage container runtimes efficiently and add the Kubernetes package repository to install components like Kubeadm, Kubelet, and Kubectl.
Initialize the Kubernetes cluster on the master node using Kubeadm and join worker nodes to the cluster.
Install the Calico network plugin to enable network communication between nodes and ensure they are Ready status.
Test the Kubernetes installation by creating and exposing an NGINX deployment, checking namespace and deployment status, exposing a service, and accessing the application.

Terraform provides more flexible controls with project-owned variable sets

HCP Terraform and Terraform Enterprise introduce project-owned variable sets to provide more flexible control and simplify configuration management.
Project-owned variable sets allow users to define variables once and reuse them across multiple workspaces within a project.
Previously, variable sets could only be managed at the organization level or workspace level, limiting flexibility.
This new feature enables variable sets to be owned at the project level, offering custom permission settings.
Teams gain self-service control over their variable sets, reducing dependencies and enhancing access control.
Challenges solved by project-owned variable sets include granular permission control and variable reuse within projects.
Previously, managing variable sets with project-level permission was not possible, posing security and operational challenges.
Workarounds like requesting platform teams to create variable sets or duplicating variables across workspaces were cumbersome.
Project-owned variable sets offer three scopes: Global, Project-specific, and Workspace-specific.
Benefits of project-owned variable sets include simplified management, granular control, and increased operational efficiency.
