Deploying Applications

This guide covers deploying a managed application from the PaaS Cloud marketplace using the web dashboard.

Prerequisites

In the dashboard, navigate to the Marketplace.
Browse or search for the application you want to deploy (e.g., PostgreSQL, Redis, Harbor).
Each application is a Cozystack application package (Helm chart bundle) with predefined Application, Bundle, and Version resources.

Click the application tile to open its details.
Review the description, resource requirements, and configurable parameters (parameter schema).

Most applications require you to set at least the following:

Name — A unique identifier for your instance within the tenant.
Resource sizing — CPU/memory requests and limits. Some applications offer resource presets similar to VM instance types.
Storage — Persistent volume size and storage class (e.g., replicated backed by LINSTOR/DRBD).
Credentials / secrets — Initial passwords or tokens (store these securely).
Networking — Whether the service should be reachable internally or exposed externally.

Tip

Start with small resource sizes for testing. You can scale vertically or request more quota later.

Return to your Console list.
Wait for the status to change to Ready.
Open the instance details to find connection endpoints, credentials, and status events.

From within the cluster: Use the internal service DNS name provided in the instance details.
From outside: If the application supports external access, follow the Exposing Services guide to create an Ingress or LoadBalancer.

Update: Open the instance in the dashboard and edit its parameters. The platform will apply changes following a rolling update when supported.
Delete: Use the instance action menu and confirm deletion. Back up important data beforehand.

Creating Virtual Machines — Deploy traditional VMs when containers are not enough.
Exposing Services — Publish your application to the internet.
Monitoring and Logs — Observe application health and logs.
