This article mainly introduces the relevant knowledge of what the three principles of GitOps are, the content is detailed and easy to understand, the operation is simple and fast, and has a certain reference value. I believe you will gain something after reading this GitOps three principles article. Let's take a look at it.

GitOps can be summarized as the following principles:

1. Everything that can be described must be stored in git

By using Git as a source of development facts, practitioners can observe the cluster and compare it with the desired state. Policies, code, configuration items, and even monitoring events and versioning can be implemented. After everything is placed in the version control system, all the changes we submit are aggregated, so that the code we submit that has not been applied is likely to be reapplied.

two。 Cannot use Kubectl directly

In general, it is not a good idea to use the command line toolset "kubectl" to deploy directly to the cluster. Many people use their CI tools to drive deployment, but doing so may lead to well-known security vulnerabilities for product development.

3. Use Kubernetes controllers that conform to the mode of operation

With a Kubernetes controller that follows the mode of operation, your cluster is always in sync with the "real source" through the checked Git configuration file. Because the expected state of your cluster is saved in Git, you can observe the difference between it and the running cluster.

Alexis further elaborated on the third point, describing how to observe the differences by comparing the required states in Git with the running cluster states, and to alert your team when the two states are out of sync. By installing the Kubernetes operator in the cluster, deployment is not only more secure from an authentication perspective, but also allows for effective control and feedback loops. Your team can use this data to iterate and improve product features and updates to the cluster infrastructure.
