Kafka Connect
Create and Control Connectors and Tasks with kPow

Access Control

User permissions to Kafka cluster resources are defined by Connect actions.

Configuration

kPow connects to a Connect cluster with environment variables.
Variable
Description
CONNECT_REST_URL
The client connection URL for your connect cluster
CONNECT_AUTH
BASIC if basic authentication is configured
CONNECT_BASIC_AUTH_USER
Username if basic authentication is configured
CONNECT_BASIC_AUTH_PASS
Password if basic authentication is configured
CONNECT_OFFSET_STORAGE_TOPIC
(Optional) Topic that holds connect offsets
CONNECT_GROUP_ID
(Optional) Unique string identifying worker cluster group
CONNECT_PERMISSIVE_SSL
True if SSL certificate validation should be disabled
CONNECT_TIMEOUT_MS
The timeout value in ms for all HTTP requests made to a Kafka Connect cluster. Default: 5000
CONNECT_RESOURCE_IDS
Optional, comma separated list of unique ids. Only specify when configuring multiple connect clusters​

Configuring Multiple Connect Clusters

kPow supports multiple Kafka Connect clusters associated to a single Kafka cluster.
To configure multiple Kafka Connect clusters, use the environment variable CONNECT_RESOURCE_IDS to define a comma separated list of Connect clusters. kPow uses the resource ID as a prefix in the environment variable.
Example configuration when configuring two Kafka Connect clusters:
1
CONNECT_RESOURCE_IDS=US1,EU2
2
US1_CONNECT_REST_URL=http://us1-connect.mycorp.org:8003
3
EU2_CONNECT_REST_URL=http://eu2-connect.mycorp.org:8003
Copied!
In this example we have defined a connection to two Kafka Connect resources: US1 and EU2
kPow's startup log message confirming it has connected to both Connect clusters.
Multiple Connect Clusters are navigable via the left hand or context menus.
