Zookeeper and Kafka link about docker-it-scala

[bjgbeelen]

I ran into the same issue when I had to switch from the DockerJava executor to the Spotify one (the spotify implementation has better/correct AuthConfig).

I created a pull which enables container linking when using the Spotify docker executor, see #62

Which docker executor you are using? If Spotify one, then it doesn't support container links I think

Ah, this might be a reason, I use Spotify one

Btw, in my experience using the LogLineContains ready checker for Kafka isn't working properly.
I'm running a custom ready checker that uses a ZooKeeper client to check the brokers have registered:

.withReadyChecker(
        DockerReadyChecker.F { _ ⇒
          zookeeperAddress.map { address ⇒

            val zkUtils = ZkUtils(
              address.getHostName + ":" + address.getPort,
              10.seconds.toMillis.toInt,
              10.seconds.toMillis.toInt,
              false
            )

            val hasBrokers = zkUtils.getChildren("/brokers/ids").nonEmpty
            zkUtils.close()

            hasBrokers
          }
        }
          .looped(nrOfReadyCheckRetries, readyCheckDuration)
      )

There is a latest working example with container linking introduced here https://github.com/whisklabs/docker-it-scala/pull/74/files
