# Camel-Kafka-connector SSH Sink

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

## Standalone

### What is needed

- An SSH server

### Setting up an SSH server

We'll use a docker image for this purpose. Any docker image with ssh enabled should be ok.

```
> docker run -d -P --name test_sshd rastasheep/ubuntu-sshd:14.04
d77dfccf3a5fe96dfa04b48a359edf572953b1b2086cab498ea7d52830eca5ee
```

Now we need to check where the port 22 has been exposed into the host

```
> docker port test_sshd 22
0.0.0.0:32768
```

So we'll point to localhost and port 32768

### 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

In this example we'll use `/home/oscerd/connectors/`

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

Now it's time to setup the connectors

Open the SSH sink configuration file

```
name=CamelSshSinkConnector
connector.class=org.apache.camel.kafkaconnector.ssh.CamelSshSinkConnector
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=32768
camel.sink.endpoint.username=root
camel.sink.endpoint.password=root
```

Now you can run the example

```
$KAFKA_HOME/bin/connect-standalone.sh $KAFKA_HOME/config/connect-standalone.properties config/CamelSshSinkConnector.properties
```

In another terminal, using kafkacat, you should be able to send messages

```
> echo "touch example.txt" | ./kafkacat -b localhost:9092 -t mytopic
% Auto-selecting Producer mode (use -P or -C to override)
> echo "echo 'My raw data line 1' >> example.txt" | ./kafkacat -b localhost:9092 -t mytopic
% Auto-selecting Producer mode (use -P or -C to override)
> echo "echo 'My raw data line 2' >> example.txt" | ./kafkacat -b localhost:9092 -t mytopic
% Auto-selecting Producer mode (use -P or -C to override)
> echo "echo 'My raw data line 3' >> example.txt" | ./kafkacat -b localhost:9092 -t mytopic
% Auto-selecting Producer mode (use -P or -C to override)
```

Now we can check our docker container.

```
> ssh root@localhost -p 32768
root@localhost's password: 
Last login: Wed Nov 25 13:10:18 2020 from 172.17.0.1
root@d77dfccf3a5f:~# cat example.txt 
My raw data line 1
My raw data line 2
My raw data line 3
```
