This is an example for Camel-Kafka-connector SFTP Sink
We’ll use the emberstack/sftp docker image
Run the following command:
docker run -p 24:22 -d emberstack/sftp --name sftp
1cb0cdd7b9a24112ecb9e4c7e195f01552e0c9187a173e29e6642c1f9d9b3455
We are mapping container port 22 to host port 24 for convenience.
take note of the container id. In our case it is 1cb0cdd7b9a24112ecb9e4c7e195f01552e0c9187a173e29e6642c1f9d9b3455
$KAFKA_HOME/bin/zookeeper-server-start.sh $KAFKA_HOME/config/zookeeper.properties
$KAFKA_HOME/bin/kafka-server-start.sh $KAFKA_HOME/config/server.properties
$KAFKA_HOME/bin/kafka-topics.sh --create --bootstrap-server localhost:9092 --replication-factor 1 --partitions 1 --topic mytopic
You’ll need to setup the plugin.path property in your kafka
Open the $KAFKA_HOME/config/connect-standalone.properties
and set the plugin.path
property to your choosen location
Now it’s time to setup the connector
You’ll need to set up the plugin.path
property in your kafka
Open the $KAFKA_HOME/config/connect-standalone.properties
and set the plugin.path
property to your choosen location:
...
plugin.path=/home/oscerd/connectors
...
Download the connector package tar.gz and extract the content to the plugin.path directory. In this example we’ll use /home/oscerd/connectors/
> cd /home/oscerd/connectors/
> wget https://repo1.maven.org/maven2/org/apache/camel/kafkaconnector/camel-sftp-kafka-connector/0.10.0/camel-sftp-kafka-connector-0.10.0-package.tar.gz
> untar.gz camel-sftp-kafka-connector-0.10.0-package.tar.gz
Open the SFTP sink configuration file
name=CamelSftpSinkConnector
connector.class=org.apache.camel.kafkaconnector.sftp.CamelSftpSinkConnector
key.converter=org.apache.kafka.connect.storage.StringConverter
value.converter=org.apache.kafka.connect.storage.StringConverter
topics=mytopic
camel.sink.path.host=localhost
camel.sink.path.port=24
camel.sink.path.directoryName=demos/
camel.sink.endpoint.username=demo
camel.sink.endpoint.password=demo
camel.sink.endpoint.fileName=mydata-${date:now:yyyyMMdd}.txt
camel.sink.endpoint.fileExist=append
Now you can run the example
$KAFKA_HOME/bin/connect-standalone.sh $KAFKA_HOME/config/connect-standalone.properties config/CamelSftpSinkConnector.properties
Now we need to provide data to SFTP server.
In another terminal, using kafkacat, you should run the following command
echo "File test" | ./kafkacat -b localhost:9092 -t mytopic
% Auto-selecting Producer mode (use -P or -C to override)
On a different terminal connect to the docker container
> docker exec -it 1cb0cdd7b9a24112ecb9e4c7e195f01552e0c9187a173e29e6642c1f9d9b3455 bash
root@1cb0cdd7b9a2:/app#
root@1cb0cdd7b9a2:/app# cd /home/demo/sftp/
root@1cb0cdd7b9a2:/home/demo/sftp# cd demos/
root@1cb0cdd7b9a2:/home/demo/sftp/demos# cat mydata-20201105.txt
File test
root@1cb0cdd7b9a2:/home/demo/sftp/demos#
As you see there is a file correctly named containing the record value we sent to Kafka.
