sven-lange-last edited a comment on issue #4430: Update docker client version to 18.06.3 URL: https://github.com/apache/incubator-openwhisk/pull/4430#issuecomment-491269350 @style95 thanks a lot for the valuable discussion and your recent updates. Jenkins is working now. We still have two different problems in Travis: * The code scanner complains about whitespace. * `services.KafkaConnectorTests > Kafka connector should send and receive a kafka message even after shutdown one of instances` fails because a remote Docker daemon cannot be connected. The problem with `services.KafkaConnectorTests` is in the last line of this code snippet: https://github.com/style95/openwhisk/blob/faf765cd9d3fedd3139298a19f911247f127c91a/tests/src/test/scala/services/KafkaConnectorTests.scala#L146-L152 ``` if (kafkaHosts.length > 1) { it should "send and receive a kafka message even after shutdown one of instances" in { kafkaHosts.indices.foreach { i => val message = createMessage() val kafkaHost = kafkaHosts(i).split(":")(0) val startLog = s", started" val prevCount = startLog.r.findAllMatchIn(commandComponent(kafkaHost, "logs", s"kafka$i").stdout).length ```
