Fenrus is a monitoring and alerting tool for Kubernetes clusters. In this tutorial, we will cover the installation of Fenrus on Fedora CoreOS Latest.
Before proceeding with the installation process, make sure the following requirements are met:
To begin with the installation process, clone the Fenrus GitHub repository on your local machine. Run the following command in the terminal:
$ git clone https://github.com/revenz/fenrus.git
This will create a local copy of the Fenrus repository in your current directory.
Once you have cloned the repository, move into the Fenrus directory by running the following command:
$ cd fenrus
Now, run the following command to install Fenrus on your Fedora CoreOS Latest cluster:
$ kubectl create -f deployment.yaml
This command will create a deployment resource for Fenrus that will be used to create a deployment in your Kubernetes cluster.
To verify that Fenrus has been successfully installed on your cluster, run the following command:
$ kubectl get pods
This command will show you a list of all the pods that are currently running on your cluster. You should see a Fenrus pod running in the list.
Finally, to access the Fenrus dashboard, you need to expose the service running on the pod. Run the following command:
$ kubectl expose deployment fenrus --type=NodePort --name=fenrus-service
This command will create a service named fenrus-service that will expose the Fenrus deployment to the external network. Get the service details by executing the following command:
$ kubectl describe service fenrus-service
This command will show you the service details, including the NodePort that you need to use to access the Fenrus dashboard. Copy the NodePort and use it to access the Fenrus dashboard from your browser. For example:
http://<node-ip>:<node-port>
Replace <node-ip> and <node-port> with the IP address of one of your cluster nodes and the NodePort, respectively.
In this tutorial, you learned how to install Fenrus on Fedora CoreOS Latest. Fenrus provides monitoring and alerting capabilities for Kubernetes clusters, and the installation process is quick and easy. With Fenrus, you can keep track of your cluster's health and take action in case of any issues.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
