Prerequisites No mongo server on localhost  A reachable mongo server instance    Steps 1. Create a fuse spring boot project  export FUSE_ARCHETYPE_VERSION=2.2.0.fuse-sb2-780040-redhat-00002 mvn org.apache.maven.plugins:maven-archetype-plugin:2.4:generate \   -DarchetypeCatalog=https: //maven.repository.redhat.com/ga/io/fabric8/archetypes/archetypes-catalog/${FUSE_ARCHETYPE_VERSION}/archetypes-catalog-${FUSE_ARCHETYPE_VERSION}-archetype-catalog.xml \   -DarchetypeGroupId=org.jboss.fuse.fis.archetypes \   -DarchetypeArtifactId=spring-boot-camel-archetype \   -DarchetypeVersion=${FUSE_ARCHETYPE_VERSION} 2. Add maven dependency           <dependency>             <groupId> org.apache.camel </groupId>             <artifactId> camel-mongodb3-starter </artifactId>         </dependency>   3. Define a mongoClient @Bean public MongoClient mongoClient(){ return new MongoClient( new MongoClientURI( "mongodb: //admin:password@192.168.99.102:32553" )); }   4. Change route to perform an insert operation on mongo @Override public void configure() throws Exception { from( "timer: //foo?period=5000" ) .setBody().constant( "{\" val\ ": \" foobar\ "}" ) .to( "mongodb3:mongoClient?database=test&collection=sampleCollection&operation=insert" ); }     Unexpected Result 12:01:12.644 [main] INFO  c.redhat.saiello.fusemongo.Application - Started Application in 6.461 seconds (JVM running for 8.69)12:01:12.644 [main] INFO  c.redhat.saiello.fusemongo.Application - Started Application in 6.461 seconds (JVM running for 8.69)12:01:12.811 [cluster-ClusterId{value= '60e6cce7665549478a7f2fbe' , description= ' null ' }-localhost:27017] INFO  org.mongodb.driver.cluster - Exception in monitor thread while connecting to server localhost:27017com.mongodb.MongoSocketOpenException: Exception opening socket at com.mongodb.internal.connection.SocketStream.open(SocketStream.java:70) at com.mongodb.internal.connection.InternalStreamConnection.open(InternalStreamConnection.java:128) at com.mongodb.internal.connection.DefaultServerMonitor$ServerMonitorRunnable.run(DefaultServerMonitor.java:117) at java.lang.
