What is the difference between masked and protected variables?

Masked variables are hidden in job logs, while protected variables are only passed to jobs running on protected branches or tags to ensure production secrets aren't accessible to dev branches.

How does this skill improve GitLab CI/CD security?

It provides standardized patterns for masking variables, using protected branches, and integrating with dedicated secret managers to prevent credential exposure in logs or code.

What are file-type variables used for?

File-type variables are ideal for sensitive data that must be present as a file on the runner, such as Kubeconfig files, SSH keys, or SSL certificates.

Does it support external secret managers?

Absolutely. It covers integration patterns for HashiCorp Vault, AWS Secrets Manager, and Azure Key Vault directly within the gitlab-ci.yml file.

Can I use this for AWS or Azure authentication?

Yes, the skill includes specific configurations for OIDC authentication, allowing GitLab jobs to assume roles in AWS or Azure without storing permanent access keys.

Deployment & DevOps

Secures and manages GitLab CI/CD variables, external secret providers, and OIDC authentication patterns.

About

This skill provides expert guidance for configuring and securing sensitive data within GitLab CI/CD pipelines. It assists developers in implementing secure variable scoping, masking sensitive values, and managing file-type variables for certificates and keys. The skill specializes in integrating external secret management solutions like HashiCorp Vault, AWS Secrets Manager, and Azure Key Vault, while promoting advanced security practices such as OpenID Connect (OIDC) authentication to eliminate the need for long-lived credentials. By following these implementation patterns, teams can ensure their deployment pipelines remain compliant and protected against credential leakage.
