When you’re running a relatively small cluster, you might get away with having no structure in place for it. But with time, your cluster will inevitably scale to dozens of pods and hundreds of containers. If you keep running them carefree, you’ll deal with a mess sooner rather than later. Here’s your golden ticket to get out of this chaos: Kubernetes namespace.
By keeping your cluster organized with namespaces, for more details. with completely different pricing per hour.
3. Allocate cloud waste if it’s unavoidable
It’s common for teams to end up with idle capacity. When allocating resources, you can decide which team should pay for which idle resources. Assigning such costs to the team, which is responsible for making the provisioning decision, incentivizes engineers to pay more attention to costs.
Once you allocate costs across individual workloads, you can easily aggregate them using any Kubernetes concept – starting with Kubernetes namespace and labeling to annotation and controller.
Mapping your Kubernetes cloud spend to a team, product or department is a time-consuming task if you do it manually. Luckily, there are solutions on the market that do it for you.
4. Use this free monitoring tool to track Kubernetes costs by namespaces
tool lets you check the costs of any of your workloads in real time and use any concept that works for you. Using the CAST AI free cost monitoring module, you can filter compute costs by namespaces and easily track cloud costs by team or service.
Connect your cluster and see how much you’re spending in real time.
CAST AI clients save an average of 63% on their Kubernetes bills
Connect your cluster and see your costs in 5 min, no credit card required.
FAQ
What is a namespace in Kubernetes?
A Kubernetes namespace lets engineers isolate groups of resources within one Kubernetes cluster. Namespaces are used in environments counting many users spread across multiple teams or projects.
Namespaces also provide a scope for resource names, which need to be unique within a namespace, but not across namespaces. You can’t nest namespaces inside one another, and each of your Kubernetes resources can only be in one namespace.
In Kubernetes, a pod is a unit of replication in a Kubernetes cluster. A single cluster can contain many pods, which may be related or unrelated, and grouped under namespaces. A namespace, on the other hand, offers a mechanism to organize a cluster into virtual sub-clusters, which comes in handy when different teams or projects share that Kubernetes cluster.
Kubernetes namespaces have many helpful use cases for engineers and teams:
- Namespaces let you isolate resources between teams and projects so developers can apply changes without worrying that they might affect the work of others.
- They improve security by enhancing role-based access controls (RBAC), which limit users and processes to specific namespaces.
- You can control cloud resources better by adding resource quotas to teams and ensuring that every namespace has access to a specified amount of CPU and memory.
- Namespaces offer a great way to separate the development, testing, and deployment of containerized applications. That way, your cluster can include the entire lifecycle.
