What is Replicated?
The Replicated platform lets you install, manage, support, and get insights on your applications in customer environments. With Replicated, you package and update your application using Kubernetes manifests or Helm charts, then securely distribute to any on-premises or cloud-hosted environments, including air gap.
For information about the Replicated features and components, see Replicated Components below.
For an overview of the key use cases for software vendors that Replicated serves, see the Intro to Replicated: 20 Ways We Help video.
Replicated includes components and features that make it easier for you to manage and deploy applications, and for enterprise users to install and manage their instance of your application.
The following diagram shows the Replicated components as they relate to you as a vendor packaging your application, and the deployment to an existing cluster and a cluster provisioned by Replicated kURL on a VM.
The Replicated vendor portal is the web-based user interface that you can use to package and manage applications.
You define Kubernetes manifest files, including application and Replicated custom resource manifests, using the built-in YAML editor and linter (in the Help pane). These files describe how to distribute the application. Alternatively, you can use Helm charts.
You can also manage other artifacts, such as customer license files, image registries, and release channels.
The replicated command-line interface (CLI) is the CLI for the vendor portal. The replicated CLI can be used to complete tasks programmatically, including all tasks for packaging and managing applications, and managing artifacts such as teams, license files, and so on. For more information, see Installing the replicated CLI.
Vendor API v3
The Vendor API is the API for the vendor portal. This API can be used to complete tasks programmatically, including all tasks for packaging and managing applications, and managing artifacts such as teams, license files, and so on. For more information, see Using the Vendor API V3.
Replicated KOTS installs and manages applications in a Kubernetes cluster. You can use KOTS to deploy Kubernetes applications or Helm charts securely to the following Kubernetes cluster environments:
- Existing clusters
- Embedded clusters created by Replicated kURL. See kURL below.
- Air gapped clusters
KOTS is an open source project that is maintained by Replicated. For more information, see the kots repository in GitHub.
The Replicated admin console is a graphical user interface (GUI) for interacting with KOTS. The admin console includes built-in functionality that allows users to install, manage, update, configure, monitor, backup and restore, and troubleshoot their application instances.
The kots command-line interface (CLI) is a kubectl plugin. Users can run commands with the kots CLI to install and manage their application instances with KOTS programmatically. For more information, see Installing the kots CLI.
Replicated kURL allows software vendors to create a custom Kubernetes distributions to share with their users for installation in online or air gapped environments. kURL has a built-in integration with KOTS through its KOTS add-on. With this integration, users can run a kURL installation script in their virtual machine (VM) or bare metal server that creates a cluster and then automatically installs KOTS in the cluster. Clusters created by kURL are called embedded clusters.
For information about how to install applications in embedded clusters, see Installing with kURL. For information about how to create a specification for kURL, see Creating a Kubernetes Installer.
kURL is an open source project that is maintained by Replicated. For more information, see the kURL repository in GitHub and the kURL documentation.
