We're excited to introduce Cluster Mode -- real-time visibility of the full Kubernetes configuration lifecycle from Development to Production!
## If you like OpenLens you will love the new cluster mode in Monokle Desktop
Monokle is a suite of tools designed to help developers and platform engineers manage the application configuration lifecycle in Kubernetes. It includes an open-source [Desktop application](https://monokle.io/download) for Windows, Linux, and Mac, a [cloud service](https://app.monokle.com/) integrated with GitHub, and an [open-source](https://monokle.io/blog/monokle-cli-flexible-kubernetes-yaml-validation) command-line interface that can be used to validate Kubernetes configurations as part of existing workflows.
When we started working on Monokle in August 2021, our idea was to create the best configuration management system possible for Kubernetes, and we have been adding features for developers and Platform Engineers since then. We have been steadily releasing new versions every few weeks, and up to the current release we have added support for Helm and Kustomize, templates, opa policy visualization in real time, and lately cluster inspection capabilities. We saw ourselves as a complement to other tools, helping with the configuration, while they could focus on the cluster management itself. However, some recent changes in the Lens license and the OpenLens project made their users look for a viable alternative and when they discovered Monokle Desktop, they asked for improvements to what we already had.
We have heard that, and for that reason [Monokle 1.13](https://monokle.io/blog/monokle-1-13-release) introduced a new real time cluster mode that allows you to quickly get an overview of the resources and applications running in your clusters, reducing the cognitive load involved in deploying and maintaining your application in Kubernetes and providing full end to end configuration lifecycle management for your application.
So we are introducing new features that will allow Monokle Desktop to connect to your cluster and show the information required to manage your application, at a basic level, in addition to all the validations, templating and configuration that we already support. And we are using your existing kubectl configuration, so you can start using it as soon as you download it.
## Cluster Dashboard with real-time updates
Until now, you could use Monokle to get a snapshot of the list of resources in your clusters, allowing you to use that as the source for validation and compare to local configuration. Changes in the cluster were not reflected until you hit the refresh button and the management was quite limited. Monokle 1.13 now shows any updates happening to your resources in real-time - making sure you are always viewing the resources as they are actually deployed in your cluster. In addition to real time updates, Monokle has added summary and detailed information for your clusters and their resources, making it easy to assess if your application is behaving correctly or if your cluster has enough free resources to work correctly.
This new dashboard also gives you a direct view of the CPU, memory and Storage in use by the cluster and projects, including information about the Kubernetes version used by your cluster, the container runtime and the alerts generated in your cluster.
## Logs and Terminal
Do you really need to understand how your application is working in your cluster? Is the pod behaving properly but the application is not behaving as expected. You can access the log directly in the tab available for your pods in the navigator.
And you have a dedicated link to the terminal, so you can access it directly from the application, without needing you to go to another place.
## Resources and CRDs
Monokle Desktop 1.13 shows you a list of all resource types and the associated resources installed in your cluster, so you can quickly review what is installed in your cluster. If your cluster has been extended using a CRD, Monokle will understand and group resources as instances of the new “Kind”, so you can quickly identify which of them are active.
Have you installed CertManager or Istio and you want to make sure that the DestinationRule is working? Just select the DestinationRule section of the Navigator and visualize all your installed manifests.
Do you need the IP addresses of your services, or the ports that are opened? Select services in the Navigator and the list will include those details that are important for your development.
## Monitoring Cluster Activity
How is your cluster behaving? Is there something you need to know about your cluster that can affect the way your application runs?
We have added an activity panel to the cluster dashboard in Monokle 1.13, so you can see if some event requires your attention. Right now it is read only but we plan to add additional interactions soon after this release.
## Automatic Resource Validation
Monokle constantly validates your configuration against your Kubernetes schema, links, and different kinds of policies, so it is easy for you to identify if there is something wrong with your configuration or if your cluster policy prevents it from running.
Even if your manifest is already deployed, you can check the resources inside the cluster to make sure that the configuration is compliant to policies, or whether it will be valid in the next update of your cluster. For example, you can use it to be sure that you didn’t deploy a ReplicaSet that was unintentionally using the “latest” label against your best practices, or review that the APIs used in your cluster will still be valid when you upgrade your cluster to the next major version.
## Details and state of Deployments / Pods
Monokle can now show you details of many of the resources installed on your cluster, including deployments and pods, with their reported state. You can also see incoming and outgoing links to your resources, so you can easily navigate through the components of your application.
## Resource Comparison
One of the many utilities included in Monokle is the ability to compare configurations. It doesn’t matter if you want to compare overlays of your Kustomize deployment, the configuration stored in different git branches or commits, or any of the with the actual configuration deployed in your cluster
Not only that, but you can use Monokle to make local copies of the configuration deployed in your cluster, update them and push it back to your cluster directly or storing the configuration in git, or generating a pull request.
## What’s next?
Cluster mode in Monokle is new and we have a lot of features in our roadmap that will make it better. Our next version, 2.0, will heavily improve the performance, along with a new interface that we think is better suited for interaction with configurations and clusters. Some of the things that you will be able to see in 2.0 and beyond will be:
* Performance improvements for cluster with 1000+ resources
* New resource focused UX, that will greatly improve the experience
* Graph view to quickly understand the relationship between elements and layers
* Additional improvements to the validations supported
And we plan to add new features in upcoming weeks like:
* Easily identify the parts of the YAML that are not editable, to avoid introducing changes that will not be deployable in your cluster.
* Better cluster information, including resource timelines when Prometheus is installed.
* Identify parent/child relationships using ownerRefs to provide additional insight for resources that are managed by the same owner.
We would love to have your input on all these things. We are actively talking to users to discuss use cases and problems that we can help to fix, and we are also establishing partnerships to make Monokle way more useful for your day to day work.
