Install Kaptain

IMPORTANT: Refer to the Kaptain fresh install instructions, if you already have Kaptain and want to move from 1.x to 2.x. Note that it is not possible to migrate your data.

IMPORTANT: Ensure the cluster that you want to use to deploy Kaptain is the only cluster in its workspace. Kaptain is meant to be deployed on workspaces with a single cluster.

How do you want to deploy Kaptain?

You can install Kaptain:

• On public cloud infrastructure, such as Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform (GCP).
• On a company-internal network with a physical (bare metal) or virtual infrastructure.
• On a company-internal network or VPC (virtual private cloud) without an internet connection: air-gapped/private/offline clusters.

The infrastructure you select determines the specific requirements for a successful installation.

Installation overview

To install and deploy Kaptain for the first time, proceed with these steps:

1. Ensure you have reviewed all prerequisites. If you are installing Kaptain on premises, also review the on-premise prerequisites page.

2. Add Kaptain to your DKP Catalog Applicationd according to your set-up:

   a. Networked environment

   b. Air-gapped environment for DKP 2.1

   c. Air-gapped environment for DKP 2.2

3. Deploy Kaptain on a per-Workspace basis and verify the status of deployment.

Before you begin

Kaptain is a DKP Catalog application. To use it, add it to your repository and then deploy it on selected workspaces. No downloads are necessary for networked environments. For users deploying to air-gapped environments, refer to the download page.

You can deploy Kaptain to single and multi-cluster environments. The difference between these setups is the following: In a single-cluster environment (with an Essential license), you deploy on one Management cluster only. In a multi-cluster environment (with an Enterprise license), Kaptain is deployed to either one or several Managed clusters or to Attached clusters.

You can deploy Kaptain on a per-workspace basis.
