doru1004 opened a new pull request #1916:
URL: https://github.com/apache/camel-k/pull/1916


   <!-- Description -->
   
   This patch adds a way to pass environment variables that only get resolved at integration runtime.
   
   These values can be passed as modeline options in this way:
   ```
   # camel-k: property=camel.component.kafka.brokers={{env:KAFKA_BROKERS}}
   ```
   
   This allows images built locally with `local create` to be deployed in the cloud. If the image depends on any such environment variables, their value needs to be resolved in the deployment script. This ensures that the same modeline option that is provided locally works when run in the cloud environment.
   
   Moreover it provides a safe way to pass sensitive properties such as web hooks. The value of `{{env:KAFKA_BROKERS}}` will only become available when the integrations is run.
   
   This patch also adds an `--env` flag to `kamel local run`. The command to run an existing integration image which depends on delayed values like `{{env:KAFKA_BROKERS}}` must provide the env var value on the command line explicitly:
   ```
   kamel local run --image <registry>/<image-name> --env KAFKA_BROKERS=localhost:9092
   ```
