Will it get implemented or you need to do something into it ? “No, just changing the volume value will not work. Jenkins only passes the parameter. To implement the change, the pipeline must pass the value to the infrastructure code and run an apply step.” Console itself we have to change value of volume into it Here downgraded not happened . Only upgraded happened only 16).data resources into terraform into it? 17).In case of terraform, if I am using password and I need to print the value on the console . How can I print the sensitive Values into it? Short Answer First 👉 By default, Terraform will NOT print sensitive values (like passwords).
👉 To print them, you must explicitly mark them as non-sensitive, which is NOT recommended in production. How Terraform Handles Sensitive Values * Variables marked as sensitive = true * Outputs marked as sensitive = true Terraform hides them in CLI output to avoid leaks. ===================== output "db_password" { value = var.db_password sensitive = true } 18).how do you pass the output from one module to another module into the terraform into it ? 19).which command to monitor the I’ve stats of pods into it ?

As a DevOps beginner, one of the main challenges I faced was understanding the end-to-end CI/CD pipeline and how different tools work together. Initially, tools like Git, Jenkins, Docker, and cloud platforms felt overwhelming. Another challenge was troubleshooting pipeline failures and environment-related issues. I worked on this by practicing hands-on labs, reading documentation, and learning from real-world examples. I also realized the importance of collaboration and automation in DevOps. To improve, I focused on writing simple scripts, automating small tasks, and continuously learning through projects. Overall, these challenges helped me build a strong foundation, and I’m actively improving by working on real projects and staying consistent with practice.” ==================== Linux Interview questions: ============================== 1).Can you explain me the architecture of kubernetes into it? 2).what are all the types of services which is avilble into kubernestes into it ? 3).I have to scrape the data for running nodes using monitoring agent?
