    With a couple of easy commands in the shell, and a pipeline.yaml of under 30 lines, KPOps can not only deploy a Kafka pipeline1 to a Kubernetes cluster, but also reset, clean or destroy it!
    "}, {"location": "user/what-is-kpops/#key-features", "title": "Key features", "text": "
       
    • Deploy Kafka apps to Kubernetes: KPOps allows to deploy consecutive Kafka Streams applications and producers using an easy-to-read and -write pipeline definition.
      •  
    • Manage Kafka Connectors: KPOps connects with your Kafka Connect cluster and deploys, validates, and deletes your connectors.
      •  
    • Configure multiple pipelines and steps: KPOps has various abstractions that simplify configuring multiple pipelines and steps within pipelines by sharing common configuration between different components, such as producers or streaming applications.
      •  
    • Handle your topics and schemas: KPOps not only creates and deletes your topics but also registers and deletes your schemas.
      •  
    • Clean termination of Kafka components: KPOps removes your pipeline components (i.e., Kafka Streams applications) from the Kubernetes cluster and cleans up the component-related states (i.e., removing/resetting offset of Kafka consumer groups).
      •  
    • Preview your pipeline changes: With the KPOps dry-run, you can ensure your pipeline definition is set up correctly. This helps to minimize downtime and prevent potential errors or issues that could impact your production environment.

    Environment-specific pipeline definitions
    Similarly to defaults, it is possible to have an unlimited amount of additional environment-specific pipeline definitions. The naming convention is the same: add a suffix of the form _{environment} to the filename.
    "}, {"location": "user/core-concepts/defaults/", "title": "Defaults", "text": "
    KPOps has a very efficient way of dealing with repeating settings which manifests as defaults.yaml. This file provides the user with the power to set defaults for any and all components, thus omitting the need to repeat the same settings in pipeline.yaml.
    See real-world examples for defaults.
    "}, {"location": "user/core-concepts/defaults/#features", "title": "Features", "text": ""}, {"location": "user/core-concepts/defaults/#inheritance", "title": "Inheritance", "text": "
    An important mechanic of KPOps is that defaults set for a component apply to all components that inherit from it.
    It is possible, although not recommended, to add settings that are specific to a component's subclass. An example would be configuring offset_topic under kafka-connector instead of kafka-source-connector.
    "}, {"location": "user/core-concepts/defaults/#configuration", "title": "Configuration", "text": "
    KPOps allows using multiple default values. The defaults.yaml (or defaults_<env>.yaml) files can be distributed across multiple files. These will be picked up by KPOps and get merged into a single pipeline.yaml file. KPOps starts from reading the default files from where the pipeline path is defined and picks up every defaults file on its way to where the pipeline_base_dir is defined.
    The deepest defaults.yaml file in the folder hierarchy (i.e., the closest one to the pipeline.yaml) overwrites the higher-level defaults' values.
    It is important to note that defaults_{environment}.yaml overrides only the settings that are explicitly set to be different from the ones in the base defaults file.
     defaults merge priority 
    Imagine the following folder structure, where the pipeline_base_dir is configured to pipelines:
    \u2514\u2500 pipelines\n   \u2514\u2500\u2500 distributed-defaults\n       \u251c\u2500\u2500 defaults.yaml\n       \u251c\u2500\u2500 defaults_dev.yaml\n       \u2514\u2500\u2500 pipeline-deep\n           \u251c\u2500\u2500 defaults.yaml\n           \u2514\u2500\u2500 pipeline.yaml\n
    KPOps picks up the defaults in the following order (high to low priority):
       
    • ./pipelines/distributed-defaults/pipeline-deep/defaults.yaml
      •  
    • ./pipelines/distributed-defaults/defaults_dev.yaml
      •  
    • ./pipelines/distributed-defaults/defaults.yaml
      •

    KafkaConnector is a component that deploys Kafka Connectors. Since a connector cannot be different from sink or source it is not recommended to use KafkaConnector for deployment in pipeline.yaml. Instead, KafkaConnector should be used in defaults.yaml to set defaults for all connectors in the pipeline as they can share some common settings.

    If you don't have access to an existing Kubernetes cluster, this section will guide you through creating a local cluster. We recommend the lightweight Kubernetes distribution k3s for this. k3d is a wrapper around k3s in Docker that lets you get started fast.
       
    1.  
      You can install k3d with its installation script:
       
      wget -q -O - https://raw.githubusercontent.com/k3d-io/k3d/v5.4.6/install.sh | bash\n
       
      For other ways of installing k3d, you can have a look at their installation guide.
       
      2.  
    2.  
      The Kafka deployment needs a modified Docker image. In that case the image is built and pushed to a Docker registry that holds it. If you do not have access to an existing Docker registry, you can use k3d's Docker registry:
       
      k3d registry create kpops-registry.localhost --port 12345\n
       
      3.  
    3.  
      Now you can create a new cluster called kpops that uses the previously created Docker registry:
       
      k3d cluster create kpops --k3s-arg \"--no-deploy=traefik@server:*\" --registry-use k3d-kpops-registry.localhost:12345\n
       
      4.  
    Note
    Creating a new k3d cluster automatically configures kubectl to connect to the local cluster by modifying your ~/.kube/config. In case you manually set the KUBECONFIG variable or don't want k3d to modify your config, k3d offers many other options.

    Kafka is an open-source data streaming platform. More information about Kafka can be found in the documentation. To deploy Kafka, this guide uses Confluent's Helm chart.
       
    1.  
      To allow connectivity to other systems Kafka Connect needs to be extended with drivers. You can install a JDBC driver for Kafka Connect by creating a new Docker image:
       
         
      1.  
        Create a Dockerfile with the following content:
         
        FROM confluentinc/cp-kafka-connect:7.1.3\n\nRUN confluent-hub install --no-prompt confluentinc/kafka-connect-jdbc:10.6.0\n
         
        2.  
      2.  
        Build and push the modified image to your private Docker registry:
         
        docker build . --tag localhost:12345/kafka-connect-jdbc:7.1.3 && \\\ndocker push localhost:12345/kafka-connect-jdbc:7.1.3\n
         
        3.  
       
      Detailed instructions on building, tagging and pushing a docker image can be found in Docker docs.
       
      2.  
    2.  
      Add Confluent's Helm chart repository and update the index:
       
      helm repo add confluentinc https://confluentinc.github.io/cp-helm-charts/ &&  \nhelm repo update\n
       
      3.  
    3.  
      Install Kafka, Zookeeper, Confluent's Schema Registry, Kafka Rest Proxy, and Kafka Connect. A single Helm chart installs all five components. Below you can find an example for the --values ./kafka.yaml file configuring the deployment accordingly. Deploy the services:
       
      helm upgrade \\\n    --install \\\n    --version 0.6.1 \\\n    --values ./kafka.yaml \\\n    --namespace kpops \\\n    --create-namespace \\\n    --wait \\\n    k8kafka confluentinc/cp-helm-charts\n

    Warning
    The --defaults flag is removed
    It is possible now to use multiple default values. The defaults.yaml (or defaults_<env>.yaml) files can be distributed across multiple files. These will be picked up by KPOps and get merged into a single pipeline.yaml file. KPOps starts from reading the default files from where the pipeline path is defined and picks up every defaults file on its way to where the pipeline_base_dir is defined.
    For example, imagine the following folder structure:
    \u2514\u2500 pipelines\n   \u2514\u2500\u2500 distributed-defaults\n       \u251c\u2500\u2500 defaults.yaml\n       \u251c\u2500\u2500 defaults_dev.yaml\n       \u2514\u2500\u2500 pipeline-deep\n           \u251c\u2500\u2500 defaults.yaml\n           \u2514\u2500\u2500 pipeline.yaml\n
    The pipeline_base_dir is configured to pipelines. Now if we generate this pipeline with the following command:
    kpops generate \\\n      --environment dev\n      ./pipelines/distributed-defaults/pipeline-deep/pipeline.yaml\n
    The defaults would be picked in the following order (high to low priority):
       
    • ./pipelines/distributed-defaults/pipeline-deep/defaults.yaml
      •  
    • ./pipelines/distributed-defaults/defaults_dev.yaml
      •  
    • ./pipelines/distributed-defaults/defaults.yaml
      •  
    The deepest defaults.yaml file in the folder hierarchy (i.e., the closest one to the pipeline.yaml) overwrites the higher-level defaults' values.

    • Deploy Kafka apps to Kubernetes: KPOps allows to deploy consecutive Kafka Streams applications and producers using an easy-to-read and -write pipeline definition.
      •  
    • Manage Kafka Connectors: KPOps connects with your Kafka Connect cluster and deploys, validates, and deletes your connectors.
      •  
    • Configure multiple pipelines and steps: KPOps has various abstractions that simplify configuring multiple pipelines and steps within pipelines by sharing common configuration between different components, such as producers or streaming applications.
      •  
    • Handle your topics and schemas: KPOps not only creates and deletes your topics but also registers and deletes your schemas.
      •  
    • Clean termination of Kafka components: KPOps removes your pipeline components (i.e., Kafka Streams applications) from the Kubernetes cluster and cleans up the component-related states (i.e., removing/resetting offset of Kafka consumer groups).
      •  
    • Preview your pipeline changes: With the KPOps dry-run, you can ensure your pipeline definition is set up correctly. This helps to minimize downtime and prevent potential errors or issues that could impact your production environment.

    KPOps reads its global configuration that is unrelated to a pipeline's components from config.yaml.
    Consider enabling KPOps' editor integration feature to enjoy the benefits of autocompletion and validation when configuring your pipeline.
    To learn about any of the available settings, take a look at the example below.
    config.yaml

    Environment-specific pipeline definitions
    Similarly to defaults, it is possible to have an unlimited amount of additional environment-specific pipeline definitions. The naming convention is the same: add a suffix of the form _{environment} to the filename.
    "}, {"location": "user/core-concepts/defaults/", "title": "Defaults", "text": "
    KPOps has a very efficient way of dealing with repeating settings which manifests as defaults.yaml. This file provides the user with the power to set defaults for any and all components, thus omitting the need to repeat the same settings in pipeline.yaml.
    See real-world examples for defaults.
    "}, {"location": "user/core-concepts/defaults/#features", "title": "Features", "text": ""}, {"location": "user/core-concepts/defaults/#inheritance", "title": "Inheritance", "text": "
    An important mechanic of KPOps is that defaults set for a component apply to all components that inherit from it.
    It is possible, although not recommended, to add settings that are specific to a component's subclass. An example would be configuring offset_topic under kafka-connector instead of kafka-source-connector.
    "}, {"location": "user/core-concepts/defaults/#configuration", "title": "Configuration", "text": "
    KPOps allows using multiple default values. The defaults.yaml (or defaults_<env>.yaml) files can be distributed across multiple files. These will be picked up by KPOps and get merged into a single pipeline.yaml file. KPOps starts from reading the default files from where the pipeline path is defined and picks up every defaults file on its way to where the pipeline_base_dir is defined.
    The deepest defaults.yaml file in the folder hierarchy (i.e., the closest one to the pipeline.yaml) overwrites the higher-level defaults' values.
    It is important to note that defaults_{environment}.yaml overrides only the settings that are explicitly set to be different from the ones in the base defaults file.
     defaults merge priority 
    Imagine the following folder structure, where the pipeline_base_dir is configured to pipelines:
    \u2514\u2500 pipelines\n   \u2514\u2500\u2500 distributed-defaults\n       \u251c\u2500\u2500 defaults.yaml\n       \u251c\u2500\u2500 defaults_dev.yaml\n       \u2514\u2500\u2500 pipeline-deep\n           \u251c\u2500\u2500 defaults.yaml\n           \u2514\u2500\u2500 pipeline.yaml\n
    KPOps picks up the defaults in the following order (high to low priority):
       
    • ./pipelines/distributed-defaults/pipeline-deep/defaults.yaml
      •  
    • ./pipelines/distributed-defaults/defaults_dev.yaml

    These variables can be used in a component's definition to refer to any of its attributes, including ones that the user has defined in the defaults.
    All of them are prefixed with component. and follow the following form: component.{attribute_name}. If the attribute itself contains attributes, they can be referred to like this: component.{attribute_name}.{subattribute_name}.

    If you don't have access to an existing Kubernetes cluster, this section will guide you through creating a local cluster. We recommend the lightweight Kubernetes distribution k3s for this. k3d is a wrapper around k3s in Docker that lets you get started fast.
       
    1.  
      You can install k3d with its installation script:
       
      wget -q -O - https://raw.githubusercontent.com/k3d-io/k3d/v5.4.6/install.sh | bash\n
       
      For other ways of installing k3d, you can have a look at their installation guide.
       
      2.  
    2.  
      The Kafka deployment needs a modified Docker image. In that case the image is built and pushed to a Docker registry that holds it. If you do not have access to an existing Docker registry, you can use k3d's Docker registry:
       
      k3d registry create kpops-registry.localhost --port 12345\n
       
      3.  
    3.  
      Now you can create a new cluster called kpops that uses the previously created Docker registry:
       
      k3d cluster create kpops --k3s-arg \"--no-deploy=traefik@server:*\" --registry-use k3d-kpops-registry.localhost:12345\n
       
      4.  
    Note
    Creating a new k3d cluster automatically configures kubectl to connect to the local cluster by modifying your ~/.kube/config. In case you manually set the KUBECONFIG variable or don't want k3d to modify your config, k3d offers many other options.
    You can check the cluster status with kubectl get pods -n kube-system. If all returned elements have a STATUS of Running or Completed, then the cluster is up and running.
    "}, {"location": "user/getting-started/setup/#deploy-kafka", "title": "Deploy Kafka", "text": "
    Kafka is an open-source data streaming platform. More information about Kafka can be found in the documentation. To deploy Kafka, this guide uses Confluent's Helm chart.
       
    1.  
      To allow connectivity to other systems Kafka Connect needs to be extended with drivers. You can install a JDBC driver for Kafka Connect by creating a new Docker image:
       
         
      1.  
        Create a Dockerfile with the following content:
         
        FROM confluentinc/cp-kafka-connect:7.1.3\n\nRUN confluent-hub install --no-prompt confluentinc/kafka-connect-jdbc:10.6.0\n
         
        2.  
      2.  
        Build and push the modified image to your private Docker registry:
         
        docker build . --tag localhost:12345/kafka-connect-jdbc:7.1.3 && \\\ndocker push localhost:12345/kafka-connect-jdbc:7.1.3\n
         
        3.  
       
      Detailed instructions on building, tagging and pushing a docker image can be found in Docker docs.
       
      2.  
    2.  
      Add Confluent's Helm chart repository and update the index:
       
      helm repo add confluentinc https://confluentinc.github.io/cp-helm-charts/ &&  \nhelm repo update\n
       
      3.  
    3.  
      Install Kafka, Zookeeper, Confluent's Schema Registry, Kafka Rest Proxy, and Kafka Connect. A single Helm chart installs all five components. Below you can find an example for the --values ./kafka.yaml file configuring the deployment accordingly. Deploy the services:
       
      helm upgrade \\\n    --install \\\n    --version 0.6.1 \\\n    --values ./kafka.yaml \\\n    --namespace kpops \\\n    --create-namespace \\\n    --wait \\\n    k8kafka confluentinc/cp-helm-charts\n
       
      4.

    KPOps handles long (more than 53 characters) Helm releases names differently. Helm will not find your (long) old release names anymore. Therefore, it is recommended that you should once destroy your pipeline with KPOps v2 to remove old Helm release names. After a clean destroy, re-deploy your pipeline with the KPOps v3.
    For example if you have a component with the Helm release name example-component-name-too-long-fake-fakefakefakefakefake. The new release name will shorten the original name to 53 characters and then replace the last 6 characters of the trimmed name with the first 5 characters of the result of SHA-1(helm_release_name).

    The template method of every pipeline component has been renamed to manifest as it is no longer strictly tied to Helm template. Instead, it can be used to render the final resources of a component, such as Kubernetes manifests.
    There is also a new kpops manifest command replacing the existing kpops generate --template flag.

    Warning
    The --defaults flag is removed
    It is possible now to use multiple default values. The defaults.yaml (or defaults_<env>.yaml) files can be distributed across multiple files. These will be picked up by KPOps and get merged into a single pipeline.yaml file. KPOps starts from reading the default files from where the pipeline path is defined and picks up every defaults file on its way to where the pipeline_base_dir is defined.
    For example, imagine the following folder structure:
    \u2514\u2500 pipelines\n   \u2514\u2500\u2500 distributed-defaults\n       \u251c\u2500\u2500 defaults.yaml\n       \u251c\u2500\u2500 defaults_dev.yaml\n       \u2514\u2500\u2500 pipeline-deep\n           \u251c\u2500\u2500 defaults.yaml\n           \u2514\u2500\u2500 pipeline.yaml\n
    The pipeline_base_dir is configured to pipelines. Now if we generate this pipeline with the following command:
    kpops generate \\\n      --environment dev\n      ./pipelines/distributed-defaults/pipeline-deep/pipeline.yaml\n
    The defaults would be picked in the following order (high to low priority):
       
    • ./pipelines/distributed-defaults/pipeline-deep/defaults.yaml
      •  
    • ./pipelines/distributed-defaults/defaults_dev.yaml
      •  
    • ./pipelines/distributed-defaults/defaults.yaml
      •  
    The deepest defaults.yaml file in the folder hierarchy (i.e., the closest one to the pipeline.yaml) overwrites the higher-level defaults' values.
