How do I connect to MongoDB with Camel-K (version 1.6.0) ?
I've tried setting the host name directly on the MongoDB Camel component URI:
...
.to("mongodb:mongoBean?database=[redacted]&collection=[redacted]&hosts=[redacted]&username=[redacted]&password=[redacted]&operation=getDbStats")
but it insists on calling 127.0.0.1:27017
:
com.mongodb.MongoTimeoutException: Timed out after 30000 ms while waiting to connect. Client view of cluster state is {type=UNKNOWN, servers=[{address=127.0.0.1:27017, type=UNKNOWN, state=CONNECTING, exception={com.mongodb.MongoSocketOpenException: Exception opening socket}, caused by {java.net.ConnectException: Connection refused (Connection refused)}}]
at com.mongodb.internal.connection.BaseCluster.getDescription(BaseCluster.java:177)
Probably I should be setting a class reference in a properties file, like so:
camel.beans.mongoBean = #class:...
but then I'm not sure what class that should be? - and what other property names to set?
The full Camel-K integration Java file I'm deploying to the Kubernetes cluster (OpenShift CodeReady containers, with the command kamel run MongoDBTest.java --dev
), looks like this:
// camel-k: language=java property=file:integration.properties
import org.apache.camel.builder.RouteBuilder;
public class MongoDBTest extends RouteBuilder {
@Override
public void configure() throws Exception {
from("timer:java?period=1000")
.routeId("java")
.to("mongodb:mongoBean?database=[redacted]&collection=[redacted]&operation=getDbStats&hosts=[redacted]&username=[redacted]&password=[redacted]")
.to("log:info");
}
}
and in the integration.properties file I have:
camel.beans.mongoBean = #class:com.mongodb.MongoClient
camel.beans.mongoBean
?The solution was to set the quarkus.mongodb... Camel Quarkus MongoDB properties, as pointed out here: https://github.com/apache/camel-k/issues/2684#issuecomment-939798018
