I am trying to start kafka and schemaregistry in docker containers using my integration tests and Test containers in Kotlin.
Here is my Test containers setup :
@Testcontainers
companion object {
@Container
val kafkaContainer = KafkaContainer(DockerImageName.parse("confluentinc/cp-kafka:latest")).apply {
setWaitStrategy(
Wait.defaultWaitStrategy()
.withStartupTimeout(Duration.ofSeconds(75))
)
withEmbeddedZookeeper()
.withEnv("KAFKA_LISTENERS", "PLAINTEXT://0.0.0.0:9093 ,BROKER://0.0.0.0:9092")
.withEnv("KAFKA_LISTENER_SECURITY_PROTOCOL_MAP", "BROKER:PLAINTEXT,PLAINTEXT:PLAINTEXT")
.withEnv("KAFKA_INTER_BROKER_LISTENER_NAME", "BROKER")
.withEnv("KAFKA_BROKER_ID", "1")
.withEnv("KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR", "1")
.withEnv("KAFKA_OFFSETS_TOPIC_NUM_PARTITIONS", "1")
.withEnv("KAFKA_TRANSACTION_STATE_LOG_REPLICATION_FACTOR", "1")
.withEnv("KAFKA_TRANSACTION_STATE_LOG_MIN_ISR", "1")
.withEnv("KAFKA_LOG_FLUSH_INTERVAL_MESSAGES", Long.MAX_VALUE.toString())
.withEnv("KAFKA_GROUP_INITIAL_REBALANCE_DELAY_MS", "0")
.start()
}.withReuse(true)
@Container
val schemaRegistryContainer = GenericContainer(DockerImageName.parse("confluentinc/cp-schema-registry")).apply {
withExposedPorts(8081)
withEnv("SCHEMA_REGISTRY_HOST_NAME", "schema-registry")
withEnv("SCHEMA_REGISTRY_LISTENERS", "http://localhost:8081")
withEnv("SCHEMA_REGISTRY_KAFKASTORE_BOOTSTRAP_SERVERS", kafkaContainer.bootstrapServers)
withNetwork(kafkaContainer.network)
start()
}
@DynamicPropertySource
@JvmStatic
fun kafkaProperties(registry: DynamicPropertyRegistry) {
registry.add("kafka.bootstrapServers") { kafkaContainer.bootstrapServers }
registry.add("kafka.schemaRegistryUrl") { "localhost:${schemaRegistryContainer.exposedPorts}" }
}
i can see that my kafka broker is up and running : enter image description here
So kafka starts first then when schema-registry is starting i see this error in docker logs :

2023-04-06 13:41:47 Using log4j config /etc/schema-registry/log4j.properties
And the schema-registry container stops after this. Any help would be much appreciated.
I expect this to start the schema -registry so that I can finally run tests
I solved this error by changing
withEnv("SCHEMA_REGISTRY_LISTENERS", "http://localhost:8081")
to
withEnv("SCHEMA_REGISTRY_LISTENERS", "http://0.0.0.0:8081")
Also
registry.add("kafka.properties.schemaRegistryUrl") { "localhost:${schemaRegistryContainer.firstMappedPort}" }
to
registry.add("kafka.properties.schemaRegistryUrl") { "http://${schemaRegistryContainer.host}:${schemaRegistryContainer.firstMappedPort}" }
Hope this helps someone :)
