The K8s tools you need to run an effective, stable, and reliable Kubernetes deployment
The biggest struggles with software development are speed and revenue. So we’re all, always, looking for ways to improve on those two issues. Kubernetes, or K8s, is one of the hottest topics in development right now. And for good reason. Kubernetes orchestration allows for robust and elegant containerization of more than one application. Hear us out.
One of the key features of Kubernetes is that it allows you to separate apps. This prevents nasty interactions, thanks to Kubernetes security. It also lets you make changes to or remove one application without impacting the others. But those aren’t even the most powerful aspects of Kubernetes. The best is that it allows for the use of a variety of tools to help when managing containers. This means increased speed and revenue.
Of course, there are a lot of Kubernetes orchestration tools out there. We’ll take a look at some of the best.

The 11 Best Kubernetes Orchestration Tools
As powerful as it may be, manually managing a large Kubernetes infrastructure can be challenging. There are ballooning cloud costs and testing, and monitoring performance, just to start. Left unchecked, Kubernetes API automation runs the risk of slimming margins and becoming impractical.
These Kubernetes orchestration tools will help you keep your Kubernetes cluster under control.
1. Helm
Helm is an open source container orchestration for Kubernetes. You can use it alongside the Kubernetes native command-line tool, kubectl. Helm simplifies the deployment of applications on a Kubernetes cluster. It does this by allowing you to define, install, and upgrade them. Helm also helps reduce manual effort by automating certain tasks.
Before utilizing tools like Helm, you need to ensure your on-premises data is securely migrated to the cloud.
DuploCloud helps organizations reduce cloud migration times by 80%. And once you’re there, DuploCloud automates deployment of Kubernetes pods. It does this through the DuploCloud Portal or through HelmCharts. Learn more about how DuploCloud can help you modernize your application through cloud migration.
2. Cloudzero
Cloudzero is one of the best Kubernetes container orchestration tools, though it is not fully open source. It helps analyze and manage costs (COGS) associated with Kubernetes deployment. It can be complicated to ascertain which application is using the most resources in a large cluster of multiple containers. Cloudzero helps track resource consumption so that you can manage your overall cloud spend and allocate resources more precisely.
Cost of goods sold (COGS) is a key performance metric for software companies. It helps calculate gross margin and demonstrate business performance. Put simply, COGS is what it costs to deliver your service to a customer.
Cloudzero helps you assess your COGS across both containerized and non-containerized infrastructure. This will help you identify costs associated with each application and the teams that produced them.
3. Prometheus
When something goes wrong (and something always goes wrong), it helps to know before it gets out of hand. Prometheus is an open-source, metrics-based monitoring system, ideal for Kubernetes monitoring. It provides insight into:
- Cluster health
- Performance tracking
- Identifying bottlenecks
Prometheus works by sending HTTP requests called “scrapes” to specific targets as determined in its configuration. It then stores the resulting data down to the node. That way, you can analyze application activity and enable alerts.
This high availability will help you alert someone when something is going wrong and provide insights into the causes. Prometheus’s database will then help you analyze trends over time so that you can predict what may go wrong next.
4. Okteto
Okteto is another tool for Kubernetes container management. It provides pre-configured environments that enable developers to build and deploy applications directly on the cloud. This allows for direct testing of apps in simulated production environments.
With Okteto as a container orchestration tool, developers can create and connect to remote namespaces. They can leapfrog over the traditional approval and deployment process and test code locally on the fly. This allows for much more rapid development and testing.
5. Ansible Kubespray
Kubespray offers a cloud native computing foundation. It is a collection of Ansible provisioning tools that allows for setting up and managing Kubernetes architecture on bare metal or any cloud platform. It is used for deploying Kubernetes clusters in environments that lack sophisticated management solutions, like chromeboxes. Kubespray requires an installation of Ansible and is compatible with most Linux distributions.
6. Kamus
Kubernetes is one of the best container orchestration platforms, it is not inherently secure. It’s not, after all, a virtual machine. Its secret values are encoded, not encrypted. This leaves the control plane vulnerable to anyone who can access the API. Therefore, if you have sensitive values, you want to keep truly secret, an encryption tool is a must.
Kamus is an open source, zero-trust secrets solution for Kubernetes. It utilizes RSA key pairs. This allows you to encrypt secret values so that they can be safely committed to source control.
7. Kubewatch
Sometimes you simply want to be notified when things are happening on your Kubernetes cluster. That’s what Kubewatch is for. It’s a Kubernetes container management tool that monitors activity across different resources. It then reports that activity to your Slack channel.
Say you want to monitor deployments. Simply configure Kubewatch to monitor deployments, and it will ping you on Slack when it detects deployments. Plus, it uses webhooks, so it is compatible with SMTP, Flock, Hip Chat, and other services.
8. Kured
Kured is a reboot daemon (KUbernetes REboot Daemon) that performs safe, automatic node reboots. It does this when called for by the package management of the underlying OS. This makes it one of the most powerful Kubernetes container orchestration tools.
Kured watches for the presence of a reboot sentinel. It then employs an API lock to ensure there is only one reboot at a time. It also reboots if Prometheus alerts are active, cordons and drains worker nodes before a reboot, and then uncordons them afterward.
9. Grafana
Grafana is a data visualization tool for Kubernetes. Think of it like an instrument cluster in an airplane. It monitors your infrastructure in real-time. This allows for notifications, alerts, performance tracking, and resource monitoring, helping you to see what resources are being used and optimize your Kubernetes orchestration.
10. Istio
In a Kubernetes environment, a service mesh improves the effectiveness and security of microservices, effectively acting as a dashboard for monitoring and controlling interactions. Enter Istio. Istio is an open-source service mesh that transparently layers on top of distributed applications. It allows you to load-balance, authenticate services, and monitor microservices with minimal code changes.
11. Flagger
Flagger is a deployment tool that facilitates automatic promotions of canary developments using Istio and other Kubernetes orchestration tools, along with Prometheus. The primary function of Flagger is to allow for deployments of updated versions of your application to controlled, limited user bases for testing purposes. Flagger will utilize the service mesh running overtop your cluster to manage traffic. And you can roll back to a more stable version if there are issues.
