Users choose to lock down the path to production in a variety of ways. The vision and philosophy for supporting users with a comprehensive strategy around CI/CD variables, pipeline permissions, deploy keys, and integrations with external key stores are contained within the Secrets Management category at GitLab.
The first component, environment variables, are dynamically-named values that impact the way running processes behave on an operating system. In CICD, these values can be secrets that determine how a job executes. Secondarily, permissions in pipelines are tokens related to how pipelines access other systems inside and outside of GitLab, which is adjacent to the third feature of deploy keys. At GitLab, when deploy keys are enabled, it uses an SSH public key to read or read-write to multiple repositories. This is a useful mechanism for sharing access to deploy between projects and automation for remote machines. Lastly, the fourth feature in Secrets Management is around integration with external key stores, of which we are prioritizing HashiCorp Vault first.
HashiCorp's Vault is paving the way for OSS Secrets Management and many of our customers are leveraging the solution today. Vault lets you easily rotate secrets and can manage intermediate, temporary tokens used between different services. This ensures there are no long-term tokens lying around or commonly used. Vault minimizes GitLab's attack surface and protects against any unknown zero-day vulnerabilities in our Rails app today or those that allow a bad actor to access the Gitlab server by ensuring that GitLab does not hold any long term secrets. See the introduction to Vault and our discussion on Vault<>GitLab Integration with our CEO @systes.
There are three main secrets management use cases that Vault will solve for. These are as follows:
Check out the 13.0 release of the GitLab <> HashiCorp Vault Integration:
Operations, compliance, security, and audit teams will derive immense value from being able to manage secrets within GitLab. In the motion of shifting security left, developers will also be empowered with the comprehensive treatment of variables and keys as a secrets in GitLab. By prioritizing external key store integrations, we will expand GitLab's security by offering an extra layer for tokens, keys, and other confidential data. This combination of tools will further establish GitLab's presence as an enterprise-grade, corporate solution for Release Management.
Now that we can effectively authenticate Vault with GitLab from (gitlab#9983), and users can install Vault into a Kubernetes clusters via (gitlab#9982), we are devoting more time to handling CI Variables from Vault. Users can now authenticate using a JSON Web Token via (gitlab#207125), to then fetch and read secrets from Vault via the implementation of (gitlab#28321). Simulataneous to this, we are beginning to investigate making pipeline permissions more flexible with a proof of concept in gitlab#221192. Lastly, we are expanding audit logs for CICD variables via gitlab#30857.
This category is currently at the "Viable" maturity level, and our next maturity target is "Complete": (see our definitions of maturity levels).
Key deliverables to move Secrets Management to "Complete" are:
In the CICD variables space, GitHub variables, offer comparable flexibility and power. They also offer a differentiation between variables and GitHub secrets, which has set an expectation in the market for a distinct treatment of those objects. We are beginning to investigate this for GitLab in gitlab#217355. GitHub Actions supports injection of HashiCorp Vault Secrets into CICD pipelines, which is directly competing with GitLab's first-to market offering of HashiCorp Vault Secrets in GitLab.
Deploy keys and tokens are an area where we can complement the GitLab permission paradigm by affording greater flexibility in job permissions. Competition wise, the GITHUB_TOKEN, is comparable and more flexible than the CI_JOB_TOKEN today, which we are working to improve in gitlab&35590.
There are other secrets management stores in the market. There is a nice overview of Vault vs. KMS which contains a lot of information about why we believe Vault is a better solution for secrets management. We could consider in the future also supporting different solutions such as KMS.
Additionally, Vault Enterprise offers additional sets of capabilities that will not be part of the open source version of Vault bundled with GitLab. This includes replication across datacenters, hardware security modules (HSMs), seals, namespaces, servicing read-only requests on HA nodes (though, the open source version does support high-availability), enterprise control groups, multi-factor auth, and sentinel.
For customers who want to use GitLab with the enterprise version of Vault, we need to ensure that this is easy to switch to/use as well.
The top focus for most accounts is to be able to easily integrate with an existing Vault instance. We will render the most value from this after we deliver (gitlab#28321), which will support the fetching and reading of secrets from Vault for CI jobs. Fit and finish features like managing secrets in the GitLab UI as described in (gitlab#218677) will reduce the barriers of entry between using Vault and GitLab together.
Our most popular issues in Secrets Management fall in the variables features set:
Another top feature in popularity is managing Vault secrets inside Gitlab (gitlab#20306). We will likely deliver on (gitlab#218677) to define Vault configuration in GitLab for CI/CD jobs and measure consumption before investing in a greater UI experience.
We have considered bundling Vault in Omnibus via (omnibus-gitlab#4317), due to it's popularity. Upon futher investigation, many of our users have an existing Vault and there is little interest in reconfiguring to use a GitLab provided Vault. Delivering a best in class integration and managed application will deliver on this need.
The most upvoted
internal customer issue in Secrets Management is around usability of build variables in gitlab#17069. The second top issue focuses on building out audit logs for CICD variables via gitlab#30857.
Additionally, our infrastructure and SecOps teams are proceeding to invest in moving GitLab's own secrets into Vault.
Internally, once the Vault integration is available we can begin moving some of the secrets tracked internally in GitLab to the included Vault.

Secrets management is a must-have for enterprise-grade release governance. Adding a proper interface to Vault (gitlab#20306) embedded in GitLab, would make it easier to interact with the Vault instance. The interface can be leveraged for all secrets, which would also be a competitive feature set for the Operations-centered and security minded buyers within the regulated space.
We are learning about the desire for there to be a greater differentiation for secrets and CICD variables via gitlab#217355. Users are rightfully expecting secrets to be truly secret to avoid leaking credentials unintentionally. This split will afford a greater fine tuning of variables within GitLab.
Features to deliver on the complaince and regulatory needs of Secrets Mangement include expansion of Audit events via (gitlab#8070) and the redefinition of a secret as a seperate entity in (gitlab#217355). Secrets are treated differently than CI/CD variables in practice although GitLab does not distinguish the experience for our users. Investing in this separation and tracking will help our position in the Zero Trust Wave and support our user's in their compliance journey.
