6.1. Overview

By default, every Kaoto release includes the latest Camel version available at the moment of the build, nevertheless, generating a different set of catalogs is possible.

6.2. Catalog generator CLI

Kaoto provides a Camel catalog generator CLI to ease this process, it supports the following runtimes:

  1. Main
  2. Quarkus
  3. Springboot

6.2.1. Using Camel catalog
Copiar o link

  1. Clone the Kaoto project
  2. Navigate to the packages/catalog-generator directory

  3. Install the project dependencies: 

    ./mvnw install
    Copy to Clipboard Toggle word wrap

  4. Run the project with the following command: 

    ./mvnw package; java -jar ./target/catalog-generator-0.0.1-SNAPSHOT.jar -o ./dist/camel-catalog -k 4.6.0 -m 4.6.0 -n "My Catalog"
    Copy to Clipboard Toggle word wrap

  5. This will generate a Catalog library containing:

    1. Camel Main 4.6.0
    2. Camel Kamelets 4.6.0
  6. The resulting files will be in the packages/catalog-generator/dist/camel-catalog folder
  7. Providing that folder through a http server will make it available for using it in Kaoto

6.2.2. Creating a Catalog library with different runtimes

  1. In order to add multiple runtimes to the Catalog library, we can provide each runtime with its version using the following flags: 

     -m,--main <version>               Camel Main version. If not specified,
                                   it will use the generator installed
                                   version
 -q,--quarkus <version>            Camel Extensions for Quarkus version
 -s,--springboot <version>         Camel SpringBoot version
    Copy to Clipboard Toggle word wrap

  2. For instance, running the following command will create a Catalog library with Camel Main 4.6.0 and Camel extensions for Quarkus 3.8.0: 

    ./mvnw package; java -jar ./target/catalog-generator-0.0.1-SNAPSHOT.jar -o ./dist/camel-catalog -k 4.6.0 -m 4.6.0 -q 3.8.0 -n "My Catalog"
    Copy to Clipboard Toggle word wrap

  3. For a different Kamelets catalog version, the --kamelets or -k flag can be specified. 

    ./mvnw package; java -jar ./target/catalog-generator-0.0.1-SNAPSHOT.jar -o ./dist/camel-catalog -k 4.5.0 -m 4.6.0  -n "My Catalog"
    Copy to Clipboard Toggle word wrap

6.2.3. Instructing Kaoto to use a specific Catalog library

    setting kaoto catalog url
    View larger image
    setting kaoto catalog url

  3. Restart Kaoto for the changes to have effect
