The hardest part to run Kubernetes in production comes at the beginning, when we transform custom scripts and automation into Kubernetes manifests and set up the cluster infrastructure. But after this, Kubernetes is a pretty stable system.
Once it’s all set up, your production infrastructure will be very low maintenance.
You can understand what the daily maintenance is like by reading the below-mentioned points, where I will run through some of the simple routine tasks you may have to complete:-
Monitor the cluster state: In order to monitor the cluster state and maintain good visibility into what's going on within the cluster is not as easy as it may sound. The workload that runs on a cluster is pretty dynamic -- new services are added, existing services’ requirements change, etc.
Install new cluster addons to extend Kubernetes’ native capabilities: There is one huge benefit of Kubernetes is that you can enhance its functionality with add-ons, so you can adapt it precisely for your needs. For example, you can set up external-dns add-ons to configure your DNS automatically for each new externally-available service.
Occasionally assist in debugging production issues: Sometimes it is very important to have at least one person on your team who understands the Kubernetes infrastructure at a more in-depth level. This understanding is not necessary to use the system, but from time to time you may have to dig a little deeper into Kubernetes’ internals to identify issues.
Improve deployment automation: In order to improve the deployment automation by doing things such as adding new features to your Helm charts.
