Trying out testcontainers for integration testing. I am testing rest api endpoint. Here is the technology stack - quarkus, RESTEasy and mongodb-client
I am able to see MongoDB container is started successfully but getting exception. Exception: "com.mongodb.MongoSocketOpenException: Exception opening socket"

If I use docker run then my test case works properly.
docker run -p 27017:27017 --name mongodb mongo:4.2
using testcontainer as mentioned @ https://www.testcontainers.org/quickstart/junit_5_quickstart/
@Container
static GenericContainer mongodb = new GenericContainer<>("mongo:4.2").withExposedPorts(27017);
I can't say for certain without seeing your test configuration, but I'm guessing that it works with docker run and not Testcontainers because docker run exposes a fixed port (always 27017) but Testcontainers will expose port 27017 as a random port (to avoid port conflicts on test machines).
To use Testcontainers with a Quarkus test, your tests must follow this flow:
Obtain randomized ports from Testcontainers after containers are started, then set any test configuration properties that depend on container ports. For example:
static GenericContainer mongodb = new GenericContainer<>("mongo:4.2").withExposedPorts(27017);
static {
mongodb.start();
System.setProperty("quarkus.mongodb.connection-string",
"mongodb://" + mongodb.getContainerIpAddress() + ":" + mongodb.getFirstMappedPort());
}
