# Camel-Kafka-connector SFTP Sink

This is an example for Camel-Kafka-connector SFTP Sink 

## Standalone

### What is needed

- An SFTP server

### Setting up SFTP Server

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

### Running Kafka

```
$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
```

### Setting up the needed bits and running the example

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

=== Configuring Kafka Connect

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:

[source]
----
...
plugin.path=/home/oscerd/connectors
...
----

=== Download the connector package

Download the connector package tar.gz and extract the content to the plugin.path directory. In this example we'll use `/home/oscerd/connectors/`

[source]
----
> cd /home/oscerd/connectors/
> wget https://repo1.maven.org/maven2/org/apache/camel/kafkaconnector/camel-sftp-kafka-connector/0.11.0/camel-sftp-kafka-connector-0.11.0-package.tar.gz
> untar.gz camel-sftp-kafka-connector-0.11.0-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.
