Davis is an open-source tool for managing Kubernetes clusters. It offers a web-based user interface that allows administrators to monitor and troubleshoot Kubernetes clusters. In this tutorial, we will guide you through the process of installing Davis on a Fedora CoreOS latest version.
Davis is a containerized application, so you need to install Docker on your Fedora CoreOS. To do this, run the following command:
$ sudo podman pull docker.io/library/docker:20.10.6
This command will download the Docker container image.
Next, we need to install Davis. To do this, clone the Davis Github repository:
$ git clone https://github.com/tchapi/davis.git
Navigate to the Davis directory:
$ cd davis
Build the Davis Docker container image:
$ sudo docker build -t davis .
This command will create a Docker image named "davis." It may take several minutes to complete.
Now that we have a Docker image, we need to deploy Davis to our Kubernetes cluster.
Create a Davis Kubernetes deployment:
$ kubectl create deployment davis --image=davis
Next, create a Kubernetes service for Davis:
$ kubectl expose deployment davis --port=8080 --target-port=8080 --type=NodePort
This command will create a Kubernetes service that exposes Davis on port 8080.
You can now access Davis by opening a web browser and navigating to http://<kubernetes-node>:<node-port>. Replace <kubernetes-node> with the IP address or hostname of one of your Kubernetes nodes, and replace <node-port> with the NodePort number you specified when creating the Davis service.
You've successfully installed Davis on your Fedora CoreOS latest version. Davis offers an easy-to-use web-based interface for monitoring and troubleshooting your Kubernetes cluster.
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!
