How to create topic with partitions in confluent kafka using curl

I have a curl command given like this i'm trying to do a curl to create a topic on confluent kafka i have an issue understanding this curl statement, on official documentation curl command is given as below 

$ curl "http://localhost:8082/topics/test"
  {"name":"test","num_partitions":3}

https://docs.confluent.io/2.0.0/kafka-rest/docs/intro.html#inspect-topic-metadata Do i have to consider {"name":"test","num_partitions":3} as data or is it a part of curl command..?

Solution

  • You're using v2.0 of the docs, I'd recommend the latest (currently 5.5)

    To create a topic you can use the new API that was added in 5.5: 

    curl -s -X POST 'http://localhost:8082/v3/clusters/rgfnzs2RS3O65A7VSpNatg/topics' \
--header 'Content-Type: application/vnd.api+json' \
--data-raw '{
  "data": {
    "attributes": {
      "topic_name": "rmoff_topic03",
      "partitions_count": 1,
      "replication_factor": 1
    }
  }
}'

    You need to get your cluster ID (rgfnzs2RS3O65A7VSpNatg in the example above), which you can do with 

    āžœ curl -s -X GET 'localhost:8082/v3/clusters'| jq '.data[0].attributes.cluster_id'
"rgfnzs2RS3O65A7VSpNatg"

    Ref: v3 API docs

    To delete a topic use the corresponding API: 

    curl -s -X DELETE 'http://localhost:8082/v3/clusters/rgfnzs2RS3O65A7VSpNatg/topics/rmoff_topic03'
