What is the core functionality of GitOps tools like Argo CD and Flux?
The core functionality of GitOps tools like Argo CD and Flux is to continuously compare the desired state, as defined in a Git repository, with the actual production state. They notify operators of any discrepancies or act to reconcile these differences automatically. This approach ensures that the production environment consistently matches the configurations specified in Git, aiding in maintaining system reliability and coherence.
An analogy for this functionality could be a thermostat in a room. The desired temperature set on the thermostat represents the configuration defined in Git, while the actual temperature in the room represents the production state. If the actual temperature deviates from the desired temperature, the thermostat (GitOps tool) will automatically adjust the heating or cooling systems to bring the room temperature back to the desired level. Similarly, GitOps tools ensure that the production state of the cluster matches the desired state defined in Git.
D. They continuously compare the desired state in Git with the actual production state and notify or act upon differences. Explanation: GitOps tools like Argo CD and Flux are designed to manage Kubernetes clusters by using Git repositories as the source of truth for cluster configuration. The core functionality of these tools involves continuously comparing the desired state of the cluster, as defined in Git, with the actual state of the cluster running in production. If there are differences between the desired and actual states, these tools will automatically reconcile those differences by either updating the production state to match the desired state or notifying operators of any discrepancies.
