 Hello Guys in this post I wish to explore more intresting instructions HEALTHCHECK which can be used in Dockerfile.  The most common requirement for any real-time projects monitoring using a side-car container which could run in parallel and try to check the process or application URL check or container reachability using ping command etc.  Dockerfie instruction HEALTHCHECK In Dockerfile we can have HEALTHCHECK instruction that allows us to know the condition of an application test runs as expected or not, when a container runs this will be returns a status as healthy, unhealthy based on the HEALTHCHECK command exit code. If the exit code 0 then returns healthy otherwise unhealthy. HEALTHCHECK [options] CMD [health check command] Example: HEALTHCHECK --interval=3s CMD ping c1 172.17.0.2 here are the Healthcheck options   --interval=time in sec (duration 30s is default)  --timeout=time in sec (duration 30s is default)  --start-period=time in ...

Hello DevSecOps and Automation Engineers! Welcome back to the DevOps Hunter blog. One of the most common requirements in enterprise automation is validating whether an application is actually available after a deployment, patching activity, server reboot, or service restart. Simply starting a service does not guarantee that the application is ready to serve users. This is where the Ansible uri module becomes one of the most powerful tools in a DevOps engineer's toolkit. In this hands-on tutorial, we will explore the Ansible URI module, understand its key parameters, and work through several real-world examples that are commonly used in production automation workflows. Production Health Check workflow using URI module What You'll Learn By the end of this article, you will be able to: Understand the purpose of the Ansible URI module Perform HTTP and HTTPS application health checks Validate application response codes Test REST API endpoints Handle multiple acceptable HTTP status...
