You can use Confluent Hub to add your desired JARs, either by installing them at runtime or by creating a new Docker image. Note that containerized Connect via Docker will be used for many of the examples in this series.Ĭonfluent maintains its own image for Kafka Connect, cp-kafka-connect-base, which provides a basic Connect worker to which you can add your desired JAR files for sink and source connectors, single message transforms, and converters. 3.2.You can run a Kafka Connect worker directly as a JVM process on a virtual machine or bare metal, but you might prefer the convenience of running it in a container, using a technology like Kubernetes or Docker. The same logic applies for the kafka-1 and kafka-2 services, where they'll be listening on ports 2902, respectively. Although zookeeper-1 and zookeeper-2 are listening on port 2181, they're exposing it to the host via ports 2211, respectively. Moreover, each service must expose a unique port to the host machine. We must ensure that the service names and KAFKA_BROKER_ID are unique across the services. KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://kafka-2:9092,PLAINTEXT_HOST://localhost:39092 KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://kafka-1:9092,PLAINTEXT_HOST://localhost:29092  KAFKA_ZOOKEEPER_CONNECT: zookeeper-1:2181,zookeeper-2:2181 So, let's add configuration for one more node each for Zookeeper and Kafka services:. Connection Using Kafka ToolĪ cluster setup for Apache Kafka needs to have redundancy for both Zookeeper servers and the Kafka servers. With that, our Kafka setup is ready for use. Kafka_1 | INFO Started socket server acceptors and processors () Kafka_1 | INFO Started data-plane acceptor and processor(s) for endpoint : ListenerName(PLAINTEXT) ()  Kafka_1 | DEBUG Started partition state machine with initial state -> HashMap() () Kafka_1 | DEBUG Started replica state machine with initial state -> HashMap() () Start Kafka ServerĬonnection to localhost port 22181 succeeded!Ĭonnection to localhost port 29092 succeeded!Īdditionally, we can also check the verbose logs while the containers are starting up and verify that the Kafka server is up: $ docker-compose logs kafka | grep -i started Similarly, the kafka service is exposed to the host applications through port 29092, but it is actually advertised on port 9092 within the container environment configured by the KAFKA_ADVERTISED_LISTENERS property. However, for any client running on the host, it'll be exposed on port 22181. In this setup, our Zookeeper server is listening on port= 2181 for the kafka service, which is defined within the same container setup. KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1 KAFKA_INTER_BROKER_LISTENER_NAME: PLAINTEXT KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: PLAINTEXT:PLAINTEXT,PLAINTEXT_HOST:PLAINTEXT KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://kafka:9092,PLAINTEXT_HOST://localhost:29092 Let's create a simple docker-compose.yml file with two services, namely zookeeper and kafka: version: '2'

1.2 How to download MacOS installer via Terminal  However, we don't want to interact with the installer, so feel free to quit the window. Once the MacOS installer has been downloaded, it will appear in the Applications folder and it will automatically be launched. Mac OS X Mountain Lion 10.8 (download link)Įach link will take you to the App Store and depending on your internet connection will take some time to download. Mac OS X Yosemite 10.10 ( Ddownload link). Mac OS X El Capitan 10.11 ( Download link). MacOS High Sierra 10.13 ( App Store link). 1.1 How to download MacOS installer from App Storeīelow, I am listing all the links for each major MacOS version to download. For the purpose of this article, we are going to use MacOS Monterey, as at the time of writing this article, is the latest major MacOS version release by Apple. Initially, we need to download the desired MacOS version which you wish to create the bootable USB installer disk from. Once you have got all the requirements down, we are ready to begin with creating the bootable USB installer disk! 1. How to create a bootable USB MacOS Install Drive? The steps On top of that, in case you ever get lost by following the steps below, I have also created a video showing you the whole process: USB-C Hub 7 ports including 3 USB 17.99$. Here is my best recommendation for an adaptor: Of course, if you decide to buy a USB stick, you will need to buy an adaptor if you Mac only has USB Type-C ports (MacBook). Of course, I am listing some recommended USB sticks which I would buy at this time: Almost every USB stick you can find on the market would be many times more than 16GB of storage. If you are looking to just buy a USB stick, then almost any option would do. Of course, if you don't have a USB stick, nor an external hard drive, then you may take a look at my other detailed article where I cover a detailed guidance on how to buy an external hard drive on budget. A USB adaptor if your Mac has only USB Type-C ports. More than 20GB of free space on your computer.  A USB stick with at least 16GB of storage or an external hard drive.  What do I need to create a bootable USB MacOS Installer In this article, I will show you how you can easily create a Bootable USB MacOS Installer drive which you can use to install on any Mac computer.  Did you buy a new Mac and you are looking to install a different MacOS version to it? Or you are looking to install MacOS Monterey (the latest MacOS at the time of writing this article) to an unsupported MacOS computer?
