Kalm (Kubernetes AppLication Manager) is an open source tool that makes it easier to manage applications on kubernetes without struggling with yamls. Kalm comes with a web interface for the most common operations including:
- Creation of new application deployments
- Deploying, updating, and scaling existing deployments
- Volume, config, and secret management
Kalm is installed as a kubernetes controller directly on your cluster, and automatically sets up istio and cert-manager, which makes it easy to configure HTTPS certificates, routes, SSO, and logging system out of the box.
Kubernetes is a powerful and flexible tool for managing microservices. However, first-time setup and configuration can be daunting. The high upfront cost makes it prohibitive for smaller teams to adopt kubernetes. We made kalm in an attempt decrease the cognitive load for developers to interact with kubernetes in both development and production environments.
Kalm tries to reduce complexity in three different ways:
- Provide an intuitive graphical inteface for the most common operations.
- Introduce higher level Custom Resource Definitions such as
Application. These CRDs help reducing the amount of boilerplate configuration and copy-pasting.
- Designed with popular extensions in mind - Kalm is designed to work with istio, cert-manager, prometheus and more, which make setting up a productive stack quick and easy.
Next, lets install Kalm and go through an example to illustrate how it works.
