GitHub - confluentinc/confluent-cli: Confluent Platform CLI Critically, for each of these steps in the release process, there is also code to roll back changes; if any step of a release fails, we can run one command to un-release before retrying. Return to file datagen-source-config.json and on line 8, replace with the copied value assigned to CLOUD_SECRET. project names are trademarks of the In VSCode, locate and open file datagen-source-config.json. This adds a decent amount of complexity to the CLI. Lets verify both the connector and task are paused using the status command. First we need to update the file containing the connector instance configuration. An advantage of this approach is that we can present a single, unified CLI experience even if underlying APIs are different. Payment information can also be entered and managed using the subcommands of ccloud admin payment. Sign up for a free Confluent Cloud account by entering the following command The Confluent CLI will automatically save them in ~/.confluent/config.json making them available for use by the CLI. The AWS CLI has commands like aws s3 cp , where s3 is a top-level command grouping or (abbreviated) product name, and cp is an abbreviated verb. Here's a code example to demonstrate this: Replace "localhost:9092" with your Kafka broker's address, and run the code. In the case of the demonstration since an EC2 instance was being used, the sample command specifies the public endpoint address assigned to the AWS EC2 instance. The reason for this is the way Kafka calculates the partition assignment for a given record. Permission issues: If you get a permission error while running the kafka-topics.sh script, make sure the script has the correct permissions. kafka-console-producer is a producer command-line tool to read data from standard input and write it to a Kafka topic. Built-in autocompletion is a convenient feature to help you quickly write commands. 1 Answer Sorted by: 0 The Confluent Cloud CLI ccloud is not a replacement for those Kafka CLI commands and confluent command is for managing a local temp cluster of the platform. document.write(new Date().getFullYear()); For instance, once youre in the ccloud shell, beginning to type kafka cluster update will result in the CLI shell suggesting IDs of Kafka clusters in your current environment, as shown in the video below. Lets set it as the active environment for the confluent CLI command. contains information on command arguments and flags, and is programmatically generated from this repository. For example, in order to list your current Kafka clusters with JSON-formatted output, you can run: Both of Confluents CLIs now support non-interactive login as well, which is particularly useful in automation scenarios. Customers should not have to install extra dependencies in order to use our CLI. Hands On: Confluent Cloud Managed Connector API. Use the Confluent CLI to create the topic: To get started, lets produce some records to your new topic. I have gone through some links and found that if ZooKeeper contains a list of brokers, and if, in this list, the IP address is present, then a kafka broker is running. In the context of GitOps for Confluent, suitable policies Amazon DynamoDB is a fully managed, serverless, key-value NoSQL database service that is highly available and scalable. On all other systems, the dependencies are statically We wanted to write code once and cross-compile with minimum extra effort. We have recently added support for new operating systems and distribution mechanisms. Note: The kc-101 cluster may already exist. To that end, we have also published official images on Docker Hub for both ccloud and confluent. Go binaries bundle all dependencies and a Go runtime into a single native binary file. The REST proxy is Confluent Community Licenced. You must copy it from the Confluent Cloud Console so that it includes your Confluent Cloud information and credentials. In cases where heavy customization is needed between cloud and on-prem Confluent deployments, we create two similarly-named files, for example. , Transactional Event QueuesAdvanced Queuing, Oracle Transactional Event QueuesAdvanced Queuing, Transactional Event QueueApache Kafka. Now we are going to produce records to our new topic. The DatagenSource connector instance appears in the list with a status of Provisioning. The CLI team is highly responsive to user feedback and is interested in hearing about both bug reports and feature requestsany way to help us serve users better. Lets now establish the downstream side of our data pipeline. Arm-based Macs ( darwin/arm64 /M1 Macs) Users with Apple's newest generation of Mac computers, which use the arm64 CPU architecture, can seamlessly run Confluent's CLIs on their machines. Confluent Platform, macOS with 64-bit Intel chips (Darwin AMD64), Windows with 64-bit Intel or AMD chips (Microsoft Windows AMD64), Linux with 64-bit Intel or AMD chips (Linux AMD64), Linux with 64-bit ARM chips (Linux ARM64), Alpine with 64-bit Intel or AMD chips (Alpine AMD64), Alpine with 64-bit ARM chips (Alpine ARM64), The independently downloaded Confluent CLI has update checks enabled Policy-as-code is the practice of permitting or preventing actions based on rules and conditions defined in code. We will use various CLI during the course exercises including confluent so these need to be available on the machine you plan to run the exercise on. During this exercise we will be streaming data to a MySQL database running on the local machine in a Docker container. Finally, newer commands like ccloud signup and user management make the CLIs more complete interfaces for Confluents rich functionality. We look forward to hearing from you! In the Confluent org being used for this demo, there is a single environment and its name is default. Since all of these APIs are built by different teams, and APIs may change frequently, the central challenges we faced were how to avoid (1) dealing with different ways of interacting with different teams APIs and (2) doing manual (and perhaps duplicative) work like adding code to call new API routes that teams add. Apache Software Confluent publishes two CLI clients, one for cloud (ccloud) and one for on-prem (confluent)though our vision is to unify these into one binary, stay tuned! This tutorial has some steps for Kafka topic management and/or reading from or writing to Kafka topics, for which you can use the Confluent Cloud Console or install the Confluent CLI. Copyright Confluent, Inc. 2014-2023. Note: If Schema Registry has already been enabled for the environment, the command will return the existing cluster details. Finally, one way that we maintain the cleanliness of our code is by using a custom linting engine that is integrated with our Cobra-based command hierarchy. You can now build powerful Docker-based automation infrastructure without ever explicitly installing one of our CLIs. Complete the following steps to set up your environment. This tutorial requires access to an Apache Kafka cluster, and the quickest way to get started free is on Confluent Cloud, which provides Kafka as a fully managed service. See the demo below, and this blog post for details. Get a list with the currently loaded connectors: Figure out where the data and the logs of the current confluent run are stored: Start on a clean slate next time (deletes data and logs of a confluent run). Confirmed.. Lets now resume the connector and its task. And finally, lets verify the previous step was successful. personal data will be processed in accordance with our Privacy Policy. I'd encourage you to dig deeper into other Kafka operations and explore more advanced features and use cases. Set CONFLUENT_HOME environment variable to point to the location of Confluent Platform. Lets continue now with our tour of using the Confluent CLI with Confluent Cloud managed connectors. Lets now create the MySQL Sink connector instance. It is now possible to sign up for Confluent Cloud right from the CLI. List all topics for a specified cluster (providing Kafka REST Proxy endpoint). Users with Apples newest generation of Mac computers, which use the arm64 CPU architecture, can seamlessly run Confluents CLIs on their machines. If operating in a non-Windows platform, you may use the In the Confluent org being used for this demo, there is a single cluster and its name is kc-101. Sometimes youll need to send a valid key in addition to the value from the command line. The only downside we have experienced is that you cant ssh into worker VMs, unlike with other tools such as SemaphoreCI. We will only share developer content and updates, including notifications when new content is added. Before proceeding, lets verify the transactions topic was created successfully. sign in management for Confluent Platform. After the consumer starts you should see the following output in a few seconds: Since we kept the --from-beginning property, youll see all the records sent to the topic. Lets start a console consumer to read only records from the first partition, 0. Now you can not only list the topics from the command line, but programmatically as well. Finally, since we have several private dependencies hosted on GitHub, it was not a fun surprise when a new Go release required us to start specifying GONOSUMDB=github.com/confluentinc and GOPRIVATE=github.com/confluentinc in our Makefilesalthough the notion of using databases to verify checksums of packages is ultimately quite useful. We use gon to notarize Apple binaries, which is required as of macOS Catalina. Kafka calculates the partition by taking the hash of the key modulo the number of partitions. Another reason we chose Go (in spite of any gripes about dependency management) is the robust ecosystem of tools in the open source community. A few of our significant top-level directories are: An advantage of our repositorys organization is that it helps enable our framework contributor model. There were several considerations that ultimately led us to decide on using Go: Go satisfies these criteria, respectively: A pain point we faced with Go is its dependency management system. It will consume records from the transactions topic and write them out to a corresponding table in our MySQL database that is running in the local Docker container that we started during the exercise environment setup steps. If you havent tried Confluent Cloud yet, you can get started by installing ccloud with a simple curl command and then running ccloud signup. Go is designed for easy networked programming, and its very fast to write code to perform HTTP requests to query APIs, for instance. At the same time, modern tech stacks such as CI/CD pipelines require large amounts of automation, which is often particularly painful to achieve with low-level infrastructure like databases and data platforms. Lets run the following command in the broker container to start a new console producer: Then enter these records either one at time or copy-paste all of them into the terminal and hit enter: After youve sent the records, you can close the producer with a CTRL+C command. This tutorial has some steps for Kafka topic management and/or reading from or writing to Kafka topics, for which you can use the Confluent Cloud Console or install the Confluent CLI. How to count messages in a Kafka topic - Confluent Lets now create a new Kafka topic named transactions. The Confluent command-line interface (CLI), confluent, enables developers to manage both Confluent Cloud and Confluent Platform and is source-available under the Confluent Community License (for more details, check out the Announcing the Source Available Confluent CLI blog post). Click on LEARN and follow the instructions to launch a Kafka cluster and to enable Schema Registry. For example, Confluent REST Proxy exposes certain cluster management features, while the Metadata Service has APIs for managing features such as RBAC and audit logs. provides significantly more functionality, including ACLs, RBAC, and Audit Log The Confluent CLI Overview shows how to get started with the Confluent CLI. When opening a PR, please make sure to follow our contribution guide. Next, lets create a Confluent Cloud cluster to use with the exercise. with the operating system. SSL Authentication with Apache Kafka | Contino Engineering - Medium For example, a reference in go.mod to a git branch or tag of a dependency is automatically changed to a version string based on a datetime and a commit hash, which is less intuitive. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. This is in contrast to Node.js, for example, where each dependency has its own tree of sub-dependencies. Starting the single-node Zookeeper instance: You can download the latest version of Kafka from the official Apache Kafka website. From simple plot types to ridge plots, surface plots and spectrograms - understand your data and learn to draw conclusions from it. Unsubscribe at any time. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Next, lets open up a consumer to read records. Perhaps we want to pause a connector instance temporarily. CLI development has made a resurgence in recent years as every prominent developer company and infrastructure provider seems to offer at least one CLI (AWS, GCP, Azure, Stripe, MongoDB, Elastic, etc.). Lets set it as the active cluster for the confluent CLI command. On line 7, replace with the copied value assigned to CLOUD_KEY. We have a simple Makefile script that tags and publishes new Docker Hub images containing our CLI for cloud or on-prem. --context string CLI context name. Our CLIs can potentially communicate with several different backends, and these various APIs must all be exposed through a single unified customer interface. We look forward to hearing from you! update command. The command will automatically obtain the cluster API key and secret from ~/.confluent/config.json but we need to specify the SR API key and secret using the --sr-apikey and --sr-apisecret parameters. By subscribing, you understand we will process your personal information in accordance with our Privacy Statement. To list all topics, you can create an instance of the AdminClient class and call the listTopics method. Lets do this now. Please update your system to MacOS 11.0 or later if you are building on Darwin/arm64. The Confluent command-line interface (CLI), confluent, enables developers to Confluent CLI executes. The video below shows how easy it is to get started with Confluent Cloud using the latest version of the CLI: ccloud shell drops you into an interactive environment with rich contextual information and helpful autocompletion for working with your Confluent Cloud infrastructure. Lets create these now. You also agree that your We will set this as the target for the Datagen source connector. It is designed to deliver single-digit millisecond query performance at any scale.
