Overview

For existing pipelines in Observability Pipelines, you can update and deploy changes for source settings, destination settings, and processors in the Observability Pipelines UI. But if you want to update source and destination environment variables, you need to manually update the Worker with the new values.

Update an existing pipeline

  1. Navigate to Observability Pipelines.
  2. Select the pipeline you want to update.
  3. Click Edit Pipeline in the top right corner.
  4. Make changes to the pipeline.
    • If you are updating the source or destination settings shown in the tiles, or updating and adding processors, make the changes and then click Deploy Changes.
    • To update source or destination environment variables, click Go to Worker Installation Steps and see Update source or destination variables for instructions.

      • Follow the instructions for your environment to update the worker:
          1. Click Select API key to choose the Datadog API key you want to use.
          2. Run the command provided in the UI to install the Worker. The command is automatically populated with the environment variables you entered earlier.
            docker run -i -e DD_API_KEY=<DATADOG_API_KEY> \
    -e DD_OP_PIPELINE_ID=<PIPELINE_ID> \
    -e DD_SITE=<DATADOG_SITE> \
    -e <SOURCE_ENV_VARIABLE> \
    -e <DESINATION_ENV_VARIABLE> \
    -p 8088:8088 \
    datadog/observability-pipelines-worker run
            Note: By default, the docker run command exposes the same port the Worker is listening on. If you want to map the Worker’s container port to a different port on the Docker host, use the -p | --publish option:
            -p 8282:8088 datadog/observability-pipelines-worker run
          3. Click Navigate Back to go back to the Observability Pipelines edit pipeline page.
          4. Click Deploy Changes.
          1. Download the Helm chart values file.
          2. Click Select API key to choose the Datadog API key you want to use.
          3. Update the Datadog Helm chart to the latest version:
            helm repo update
          4. Run the command provided in the UI to install the Worker. The command is automatically populated with the environment variables you entered earlier.
            helm upgrade --install opw \
-f values.yaml \
--set datadog.apiKey=<DATADOG_API_KEY> \
--set datadog.pipelineId=<PIPELINE_ID> \
--set <SOURCE_ENV_VARIABLES> \
--set <DESTINATION_ENV_VARIABLES> \
--set service.ports[0].protocol=TCP,service.ports[0].port=<SERVICE_PORT>,service.ports[0].targetPort=<TARGET_PORT> \
datadog/observability-pipelines-worker
            Note: By default, the Kubernetes Service maps incoming port <SERVICE_PORT> to the port the Worker is listening on (<TARGET_PORT>). If you want to map the Worker’s pod port to a different incoming port of the Kubernetes Service, use the following service.ports[0].port and service.ports[0].targetPort values:
            --set service.ports[0].protocol=TCP,service.ports[0].port=8088,service.ports[0].targetPort=8282
          5. Click Navigate Back to go back to the Observability Pipelines edit pipeline page.
          6. Click Deploy Changes.

          1. Click Select API key to choose the Datadog API key you want to use.

          2. Run the one-step command provided in the UI to re-install the Worker.

            Note: The environment variables used by the Worker in /etc/default/observability-pipelines-worker are not updated on subsequent runs of the install script. If changes are needed, update the file manually and restart the Worker.

          If you prefer not to use the one-line installation script, follow these step-by-step instructions:

          1. Run the following commands to update your local apt repo and install the latest Worker version:
            sudo apt-get update
sudo apt-get install observability-pipelines-worker datadog-signing-keys
          2. Add your keys, site (for example datadoghq.com for US1), source, and destination environment variables to the Worker’s environment file:
            sudo cat &lt;<EOF > /etc/default/observability-pipelines-worker
DD_API_KEY=<DATADOG_API_KEY>
DD_OP_PIPELINE_ID=<PIPELINE_ID>
DD_SITE=<DATADOG_SITE>
<SOURCE_ENV_VARIABLES>
<DESTINATION_ENV_VARIABLES>
EOF
          3. Restart the worker:
            sudo systemctl restart observability-pipelines-worker
          4. Click Navigate Back to go back to the Observability Pipelines edit pipeline page.
          5. Click Deploy Changes.

          1. Click Select API key to choose the Datadog API key you want to use.

          2. Run the one-step command provided in the UI to re-install the Worker.

            Note: The environment variables used by the Worker in /etc/default/observability-pipelines-worker are not updated on subsequent runs of the install script. If changes are needed, update the file manually and restart the Worker.

          If you prefer not to use the one-line installation script, follow these step-by-step instructions:

          1. Update your packages and install the latest version of Worker:
            sudo yum makecache
sudo yum install observability-pipelines-worker
          2. Add your keys, site (for example datadoghq.com for US1), source, and destination updated environment variables to the Worker’s environment file:
            sudo cat &lt;&lt;-EOF > /etc/default/observability-pipelines-worker
DD_API_KEY=<API_KEY>
DD_OP_PIPELINE_ID=<PIPELINE_ID>
DD_SITE=<SITE>
<SOURCE_ENV_VARIABLES>
<DESTINATION_ENV_VARIABLES>
EOF
          3. Restart the worker:
            sudo systemctl restart observability-pipelines-worker
          4. Click Navigate Back to go back to the Observability Pipelines edit pipeline page.
          5. Click Deploy Changes.
          1. Select the expected log volume for the pipeline from the dropdown.
          2. Select the AWS region you want to use to install the Worker.
          3. Click Select API key to choose the Datadog API key you want to use.
          4. Click Launch CloudFormation Template to navigate to the AWS Console to review the stack configuration and then launch it. Make sure the CloudFormation parameters are set as expected.
          5. Select the VPC and subnet that you want to use to install the Worker.
          6. Review and check the necessary permissions checkboxes for IAM. Click Submit to create the stack. CloudFormation handles the installation at this point; the Worker instances are launched, the necessary software is downloaded, and the Worker starts automatically.
          7. Delete the previous CloudFormation stack and resources associated with it.
          8. Click Navigate Back to go back to the Observability Pipelines edit pipeline page.
          9. Click Deploy Changes.
