http.redpanda.sasl.scram

Listens on http port 7114 or https port 7143 and will produce messages to the events topic in SASL/SCRAM enabled Redpanda cluster, synchronously.

Running locally

This cookbook runs using Docker compose.

Setup

The setup.sh script will:

installs Zilla and Redpanda to the Kubernetes cluster with helm and waits for the pods to start up
creates the user user in Redpanda
creates the events topic in Redpanda
starts port forwarding

./setup.sh

Verify behavior

Send a POST request with an event body.

curl -v \
       -X "POST" http://localhost:7114/events \
       -H "Content-Type: application/json" \
       -d "{\"greeting\":\"Hello, world\"}"

output:

...
> POST /events HTTP/1.1
> Content-Type: application/json
...
< HTTP/1.1 204 No Content

Verify that the event has been produced to the events topic in Redpanda cluster.

docker compose -p zilla-http-kafka-sync exec kafkacat \
kafkacat -b redpanda:29092 -X security.protocol=SASL_PLAINTEXT \
  -X sasl.mechanisms=SCRAM-SHA-256 \
  -X sasl.username=user \
  -X sasl.password=redpanda \
  -t events -J -u | jq .

output:

{
  "topic": "events",
  "partition": 0,
  "offset": 0,
  "tstype": "create",
  "ts": 1652465273281,

  "headers": [
    "content-type",
    "application/json"
  ],
  "payload": "{\"greeting\":\"Hello, world\"}"
}
% Reached end of topic events [0] at offset 1

Teardown

The teardown.sh script stops port forwarding, uninstalls Zilla and Redpanda and deletes the namespace.

./teardown.sh

output:

+ pgrep kubectl
99999
99998
+ killall kubectl
+ helm uninstall zilla-http-redpanda-sasl-scram zilla-http-redpanda-sasl-scram-redpanda --namespace zilla-http-redpanda-sasl-scram
release "zilla-http-redpanda-sasl-scram" uninstalled
release "zilla-http-redpanda-sasl-scram-redpanda" uninstalled
+ kubectl delete namespace zilla-http-redpanda-sasl-scram
namespace "zilla-http-redpanda-sasl-scram" deleted
