Chapter 1. Managing Camel K integrations You can manage Red Hat Integration - Camel K integrations using the Camel K command line or using development tools. This chapter explains how to manage Camel K integrations on the command line and provides links to additional resources that explain how to use the VS Code development tools. Section 1.1, "Managing Camel K integrations" Section 1.2, "Managing Camel K integration logging levels" Section 1.3, "Scaling Camel K integrations" 1.1. Managing Camel K integrations Camel K provides different options for managing Camel K integrations on your OpenShift cluster on the command line. This section shows simple examples of using the following commands: kamel get kamel describe kamel log kamel delete Prerequisites Setting up your Camel K development environment You must already have a Camel integration written in Java or YAML DSL Procedure Ensure that the Camel K Operator is running on your OpenShift cluster, for example: Enter the kamel run command to run your integration in the cloud on OpenShift. For example: Enter the kamel get command to check the status of the integration: Enter the kamel describe command to print detailed information about the integration: Enter the kamel log command to print the log to stdout : Press Ctrl-C to terminate logging in the terminal. Enter the kamel delete to delete the integration deployed on OpenShift: Additional resources For more details on logging, see Managing Camel K integration logging levels For faster deployment turnaround times, see Running Camel K integrations in development mode For details of development tools to manage integrations, see VS Code Tooling for Apache Camel K by Red Hat 1.2. Managing Camel K integration logging levels Camel K uses Quarkus Logging mechanism as the logging framework for integrations. You can configure the logging levels of various loggers on the command line at runtime by specifying the quarkus.log.category prefix as an integration property. For example: Example Note It is important to escape the property with single quotes. Prerequisites Setting up your Camel K development environment Procedure Enter the kamel run command and specify the logging level using the --property option. For example: Press Ctrl-C to terminate logging in the terminal. Additional resources For more details on the logging framework, see the Configuring logging format For details of development tools to view logging, see VS Code Tooling for Apache Camel K by Red Hat 1.3. Scaling Camel K integrations You can scale your integrations using the oc scale command. Procedure To scale the Camel K integrations, run the following command. You can also edit the Integration resource directly to scale the integration. To view the number of replicas for the integration use following command.

Commands:
get pod
