You can use the following commands:

• krakend check: Use krakend check to make sure the configuration file you have generated is not broken and has the required attributes to start the gateway.
• krakend check-plugin: Use the check-plugin when you are developing custom plugins and you want to check that they are compatible with the server.
• krakend run: Use run to start the API gateway server.
• krakend version: Use the version command to print the current KrakenD version and the Glibc and Go versions used during compilation.

Starting the gateway server

To start the server, invoke the krakend run command with a configuration file containing your API definition. You can visually create your first krakend.json file using the KrakenDesigner if you prefer a UI.

Or to get started right away, you can paste the following content inside a krakend.json file:

{
    "$schema": "https://www.krakend.io/schema/v2.2/krakend.json",
    "version": 3
}

And then you can start KrakenD:

$krakend run -c krakend.json

Or if you use Docker:

$docker run -p "8080:8080" -v $PWD:/etc/krakend/ devopsfaith/krakend:2.2 run -c krakend.json

Now KrakenD is listening on 8080, and you can see it working under http://localhost:8080/__health.
