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. Community Edition only manages KubeDB custom resources in the demo Kubernetes namespace. 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.

You can create licenses for as many clusters as you want. You can upgrade your license any time without re-installing KubeDB by following the upgrading guide from here.

KubeDB licensing process has been designed to work with CI/CD workflow. You can automatically obtain a license from your CI/CD pipeline by following the guide from here.

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"

NAME                                            READY   STATUS    RESTARTS   AGE
kubedb-kubedb-provisioner-b6696cffc-kfgmg       1/1     Running   0          69s
kubedb-kubedb-webhook-server-7dbddc467f-n4zkw   1/1     Running   0          69s

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.
