kandi X-RAY | kafka-rest Summary
The Kafka REST Proxy provides a RESTful interface to a Kafka cluster. It makes it easy to produce and consume messages, view the state of the cluster, and perform administrative actions without using the native Kafka protocol or clients. Examples of use cases include reporting data to Kafka from any frontend app built in any language, ingesting messages into a stream processing framework that doesn’t yet support Kafka, and scripting administrative actions.

I'm using a dockerized version of the Confluent Platform v 7.0.1:
...ANSWER
Answered 2022-Feb-18 at 22:37You may be hitting issues since you are running an old version of ksqlDB's quickstart (0.7.1) with Confluent Platform 7.0.1.
If you check out a quick start like this one: https://ksqldb.io/quickstart-platform.html, things may work better.
I looked for an updated version of that data generator and didn't find it quickly. If you are looking for more info about structured data, give https://docs.ksqldb.io/en/latest/how-to-guides/query-structured-data/ a read.
QUESTION
I am running Kafka and Flink as docker containers on my mac.
I have implemented Flink Job that should consume messages from a Kafka topic. I run a python producer that sends messages to the topic.
The job starts with no issues but zero messages arrive. I believe the messages are sent to the correct topic since I have python consumer that is able to consume messages.
flink job (java):
...ANSWER
Answered 2021-Nov-25 at 16:10The Flink metrics you are looking at only measure traffic happening within the Flink cluster itself (using Flink's serializers and network stack), and ignore the communication at the edges of the job graph (using the connectors' serializers and networking).
In other words, sources never report records coming in, and sinks never report records going out.
Furthermore, in your job all of the operators can be chained together, so Flink's network is not used at all.
Yes, this is confusing.
QUESTION
I have Flink (task manager and job manager) and Kafka running as docker images on my mac.
I have created a Flink job and deployed it.
The job uses FlinkKafkaConsumer and FlinkKafkaProducer and should consume from kafka and produce back to kafka.
Looks like the "bootstrap.servers" I use (kafka:9092) has no meaning for Flink which fails with:
ANSWER
Answered 2021-Nov-23 at 17:42Most likely you'll have to configure KAFKA_ADVERTISED_LISTENERS and point Flink to the configured value. For example, in my Docker setup at https://github.com/MartijnVisser/flink-only-sql I have the following configuration in my Docker compose file:

I'm using docker with kafka and clickhouse. I want to connect 'KsqlDB table' and 'clickhouse' using 'kafka connect'. So I referred to this document and modified 'docker composite'.
here is my docker-compose

Answered 2021-Nov-04 at 01:31It was solved when 'httpcomponents-client-4.5.13' was downloaded through wget. I think 'httpclient' was needed in 'clickhouse-jdbc'. I'm using clickhouse-jdbc-v0.2.6

...ANSWER
Answered 2021-Oct-27 at 14:48You seem to misunderstand Docker Compose networking. You should always be using service names, not IP addresses
If you use one Zookeeper server, ZOOKEEPER_SERVERS doesn't do anything. This is used to join a cluster
So, you're looking for this

I am pretty new to the world of docker. I have been using Docker for windows which uses the WSL2 engine. Docker commands seemed to work all fine before but I started to have some issues with my Linux distribution which led to me uninstall and reinstall my linux distribution and Docker Desktop. After the reinstallation docker-compose up -d refuses to work in detached mode(i.e I can use ctrl + C to cancel it) .
Below is my docker-compose.yml file

QUESTION
I'm trying to apply mTLS security on Kafka rest proxy and no luck. The model that I'm looking for is as below.
Browser --https://host:443/--> Kafka Rest proxy --kerberos--> Kafka Brokers
Rest-proxy to Kafka brokers is working fine, but client to rest proxy is working only with http://host:port/
My Kafka-rest.properties is as below.
...ANSWER
Answered 2021-Aug-19 at 08:50After lot of googling learnt that, PORT is deprecated when rest-proxy is deployed in k8s, so I need to define listeners="https://0.0.0.0:port". Once I added mTLS is working.

Answered 2021-Aug-12 at 15:24Docker volumes are ephemeral, so this is expected behavior.
You need to mount host volumes for at least the Kafka and Zookeeper containers

I am trying to do event streaming between mysql and elasticsearch, one of the issue I faced was with the JSON object in mysql when transfered to elasticsearch was in JSON string format not as an object.
I was looking for a solution using SMT, I found this,
I don't know how to install or load in my kafka or connect container
Here's my docker-compose file,
...ANSWER
Answered 2021-Jun-27 at 20:19to install SMT it just the same as installing other connector,
Copy your custom SMT JAR file (and any non-Kafka JAR files required by the transformation) into a directory that is under one of the directories listed in the plugin.path property in the Connect worker configuration –
In your case copy to /usr/share/confluent-hub-components
