How Git mitigates this collision risk, though is by adding dates and other metadata with a pointer to the parent code of the commit. (The problem has since been updated with a newer version of SHA-1.) This is a brute force method of attack that requires an enormous amount of computing power to accomplish. But SHA-1 hash codes can be vulnerable to collision attacks where when two SHA-1 hashes committed at the same time, one could overwrite the other and therefore put commit guarantee into question. Git uses SHA-1 hash codes as the underlying mechanism for guaranteeing code commits. Rather what it does is guarantee the provenance of the code commit. Git of course is the de facto standard for version control, however, it doesn’t really secure anything. But he stressed how keeping your Git repositories secure is now very important with this growing paradigm.

Everything kept as codeĪndrew began his talk with a discussion on how clusters and other infrastructures are almost completely declarative that can be kept in a software repository. Next, Andrew Martin from ControlPlane spoke on securing your Git repositories. GitOps provides you with a more secure way of updating your cluster, however it does shift the burden of security onto Git. For example, you can create separate policies for cluster infrastructure changes and for application deployments. In addition to having better security guarantees, since your configuration manifests are kept in its own canonical repo, you can also implement and enforce process and other constraints that you may have within your organization. Credentials between tools are read-only all along the pipeline with critical credentials and secrets kept inside of the cluster itself. The security guarantees in such a pipeline are stronger. When these principles have been put into place, you have a pipeline that is already more secure. When a change is detected between the two, an alert is sent where an action can be taken to re-adjust the cluster with the canonical source of truth. Software agents constantly compare the source of truth with the running cluster. On one side, developers push code to the canonical source of truth. Once you’ve applied the principles, this is what your system looks like in the end: The use of software agents to ensure correctness and alert on divergence.
Approved changes to the desired state are automatically applied to the system.Ĥ. The canonical desired system state is versioned somewhere.ģ. The entire system is described declaratively.Ģ. These are the four driving principles of GitOps:ġ. GitOps is ultimately a way for your team to deliver more features, faster. We use Git for our repositories, but these principles could be equally applied to Bitbucket or to Perforce or any other version control system. It is a set of principles on why rather than step by step instructions on how. GitOps is technology agnostic (despite its name). We developed this methodology at Weaveworks to manage our own Kubernetes applications and infrastructure for the last several years. How does the security improve with GitOps?īriefly, GitOps is an operations model, derived from computer science and years of operations knowledge. One of the biggest issues is the read-write credentials that are exposed from your CI tool right into your cluster, leaving you open to malicious attacks. From the left side, the developer pushes his code into the repo, and from there, the CI tool takes over and runs some tests, integrates the code, builds a container artefact, and adds it to a container registry where it eventually gets deployed to the cluster.Īs you can see from the diagram, the typical single direction, push-based pipeline has some security flaws. This is what a typical CICD pipeline looks like in most organizations.

Speakers included Andrew Martin ( ControlPlane as well as Weaveworks’ customer success engineer, Brice Fernandes ( gave us an overview of what GitOps is, and why it is a logical and more secure way for large development teams to update applications in Kubernetes. Earlier this month, Weaveworks hosted a webinar on securing your GitOps pipelines.
