KrakenD API Gateway on Ubuntu 24.04 LTS by cloudimg

## KrakenD API Gateway on Ubuntu 24.04 LTS by cloudimg

KrakenD is a stateless, declarative, high-performance API Gateway. It sits in front of your services and turns many backend calls into a single client-facing endpoint - proxying, aggregating, filtering, transforming, validating JWTs and rate-limiting traffic - all from one declarative JSON configuration with no per-request database lookups. The cloudimg image installs KrakenD 2.13 from the official apt repository as /usr/bin/krakend with krakend.service enabled on boot, and ships a ready-to-run sample config. Backed by 24/7 expert support.

Declarative API Gateway

Proxy, aggregate, filter, transform, validate JWTs and rate-limit from one declarative JSON config with no per-request database lookups. Validate any config change with the built-in krakend check before restart.

Ready-to-Run Config

A sample /etc/krakend/krakend.json listens on 0.0.0.0:8080 with the built-in /__health endpoint plus two sample endpoints: a simple backend proxy and a two-backend response aggregation.

Networking

KrakenD has no web admin UI. The gateway listens on port 8080, but the image does NOT open 8080 in any NSG - open 8080/tcp in your NSG (ideally only from a load-balancer subnet) or front KrakenD with an Azure Application Gateway terminating TLS. The gateway ships no per-VM password; you configure whatever authentication (JWT, API keys, OAuth) your APIs require.

Use Cases

An API gateway and aggregation layer, a backend-for-frontend, JWT validation and rate-limiting at the edge, and a stateless high-performance alternative to heavyweight API management platforms.
