.gitlab-ci.yml Part Nine – Basics Of Default Inherit
Hello Everyone
Welcome to CloudAffaire and this is Debjeet.
In the last blog post, we have discussed .gitlab-ci.yml features like include, extends and pages.

In this blog post, we will discuss .gitlab-ci.yml features like default and inherit.
default:
Some parameters can be set globally as the default for all jobs using the default: keyword. Default parameters can then be overridden by job-specific configuration. The following job parameters can be defined inside a default: block:
- image
- services
- before_script
- after_script
- tags
- cache
- artifacts
- retry
- timeout
- interruptible

inherit:
You can disable inheritance of globally defined defaults and variables with the inherit: parameter. To enable or disable the inheritance of all variables: or default: parameters, use the following format:
- default: true or default: false
- variables: true or variables: false
To inherit only a subset of default: parameters or variables:, specify what you wish to inherit in an array, and any not listed will not be inherited.
