Install KubeDB Community Edition

KubeDB Community edition is available under AppsCode-Community-1.0.0 license and free to use for both commercial and non-commercial purposes. It comes with the cluster provisioning functionalities. However, it lacks some advanced features such as database backup/recovery, upgrading version, horizontal and vertical scaling, TLS/SSL support via cert-manager, updating configuration post provisioning, connection pooling, etc. compared to the Enterprise edition. A full features comparison between the KubeDB Community edition and Enterprise edition can be found here.

To use the KubeDB Community edition, you can grab 1 year free license from here. After that, you can issue another license for one more year. Typically we release a new version of the operator at least quarterly. So, you can just grab a new license every time you upgrade the operator.

Get a License

In this section, we are going to show you how you can get a 1 year free license for the KubeDB Community edition. You can get a license for your Kubernetes cluster by going through the following steps:

  • At first, go to AppsCode License Server and fill-up the form. It will ask for your Name, Email, the product you want to install, and your cluster ID (UID of the kube-system namespace).

  • Provide your name and email address. You can provide your personal or work email address.

  • Then, select KubeDB Community Edition in the product field.

  • Now, provide your cluster-ID. You can get your cluster ID easily by running the following command:

    $ kubectl get ns kube-system -o=jsonpath='{.metadata.uid}'
    
  • Then, you have to agree with the terms and conditions. We recommend reading it before checking the box.

  • Now, you can submit the form. After you submit the form, the AppsCode License server will send an email to the provided email address with a link to your license file.

  • Navigate to the provided link and save the license into a file. Here, we save the license to a license.txt file.

Here is a screenshot of the license form.

Verify installation

To check if KubeDB operator pods have started, run the following command:

$ watch kubectl get pods --all-namespaces -l "app.kubernetes.io/instance=kubedb"
NAMESPACE     NAME                                        READY   STATUS    RESTARTS   AGE
kube-system   kubedb-kubedb-community-7f4dc7c49c-l6ddf    1/1     Running   0          48s

Once the operator pod is running, you can cancel the above command by typing Ctrl+C.

Now, to confirm CRD groups have been registered by the operator, run the following command:

$ kubectl get crd -l app.kubernetes.io/name=kubedb

Now, you are ready to create your first database using KubeDB.
