Getting Started with Elastic Cloud on Kubernetes

In the modern DevOps world, ELK (Elasticsearch, Logstash, and Kibana) plays a crucial role by enabling the search, analysis, and visualization of large data sets. These capabilities are essential for troubleshooting issues, gaining insights, and ensuring the security of systems.

There are several deployment options for the ELK Stack, depending on a team's requirements and the desired level of infrastructure management. One of the deployment options is Elastic Cloud on Kubernetes (ECK), an official Kubernetes Operator provided by Elastic. Elastic Cloud on Kubernetes simplifies the deployment and management of Elastic Stack components within Kubernetes clusters.

This blog explains the process of installing Elastic Cloud on Kubernetes on an Azure Kubernetes Service (AKS) cluster using YAML templates.

Managing Planned Maintenance for Azure Container Apps

Azure Container App is a fully managed Azure service that receives regular updates automatically. These updates are applied with minimal impact on the container applications. However, Azure Container App users can now define a maintenance window, allowing them to schedule service maintenance at a convenient time. This ensures application availability during important periods without downtime due to service maintenance.

There are two types of service updates, critical and non-critical updates. Critical updates are applied immediately when required, and users cannot set a maintenance window for them. However, maintenance windows can be set for non-critical updates. This blog explains how to set a maintenance window for Azure Container App using a GitHub Action pipeline.

Conditional Variable Assignment in Azure DevOps Pipelines

Azure DevOps pipeline expression functions enable the creation of powerful Azure DevOps YAML pipelines to achieve various advanced automation needs for build and deployment purposes. This blog explains how to use the if condition with pipeline variable values.

In an Azure DevOps YAML pipeline, a variable if condition can be defined as follow

iif(condition, the_value_returns_when_condition_true, the_value_returns_when_condition_false)
