'''Video summary:''' "Oxypc CICD Deployment KT DESHWAL" -- an English-language KT session on the CI/CD pipeline built for OxyPC, a separate PHP (Yii2 framework) project deployed to `/var/www/html/oxypc`, hosted on GitHub and deployed via Jenkins (chosen over alternatives like GitHub Actions/GitLab CI). Walks through the Jenkins pipeline stage by stage: a checkout-from-SCM stage using stored Git credentials against the main branch (built using Jenkins' "generate pipeline syntax" helper); a code-review/validation stage that runs a PHP lint/syntax check (`php -l`-style check) -- currently commented out on the development pipeline at the developers' request, but still active on staging, demonstrated live by intentionally introducing a PHP parse error and showing the check catch it; a backup stage that snapshots the current deployed code into a dedicated backup directory under `/opt` with its own retention policy before the new code is deployed; the actual deployment stage that syncs the checked-out code to the live path; and a post-deployment stage that emails a designated group (the presenter plus two others) automatically if the build fails. Explains the GitHub webhook integration that makes deployment fully automatic: a developer push to GitHub fires a webhook that Jenkins listens for, which kicks off the entire pipeline (checkout -> validate -> backup -> deploy -> notify) without manual triggering -- noting the presenter doesn't have direct access/credentials to the GitHub webhook config itself (owned by the client's dev team) but can describe the flow. Closes by briefly showing a `sudoers` entry added for the Jenkins user to allow the specific commands the pipeline needs without a password prompt.
