Creating a pipeline through script involves defining stages, tasks, and triggers in a script file.

• Define stages for each step in the pipeline

• Define tasks for each stage, such as building, testing, and deploying

• Define triggers for each stage, such as manual or automatic triggers

Docker image has 3 layers: Base, Dependencies and Application.

• Base layer contains the OS and other system-level libraries.

• Dependencies layer contains the libraries and packages required by the application.

• Application layer contains the code and files specific to the application.

• Each layer is read-only and builds on top of the previous layer.

• Changes made to one layer do not affect the other layers.

• This layering approach makes Docker images lightweight and easy to share.

A fault domain is a logical group of hardware components that share a common power source and network switch.

• By distributing resources across fault domains, system failures can be isolated and minimized.

• Examples of fault domains include racks in a data center or availability zones in a cloud provider.

• In the event of a power outage or network failure in one fault domain, the system ca...read more

Webhooks in Jenkins are a way to trigger a build or perform an action in response to an external event.

• Webhooks allow Jenkins to receive notifications from external systems.

• They are typically used to trigger a build when a code repository is updated.

• Webhooks can be configured to send JSON or XML payloads to Jenkins.

• Jenkins can parse the payload and take actions based on the received data.

• Webhooks can be set up for various events like code commits, pull requests, etc.
