Where to set env variables for local Spring Cloud Dataflow?

问题

For development, I'm using the local Spring Cloud Dataflow server on my Mac, though we plan to deploy to a Kubernetes cluster for integration testing and production. The SCDF docs say you can use environment variables to configure various things, like database configuration. I'd like my registered app to use these env variables, but they don't seem to be able to see them. That is, I start the SCDF server by running its jar from a terminal window, which can see a set of environment variables. I then configure a stream using some Spring Cloud stream starter apps and one custom Spring Boot app. I have the custom app logging System.getenv() and it's not showing the env variables I need. I set them in my ~/.bashrc file, which I also source from ~/.bash_profile. That works for my terminal windows and most other things that need environment, but not here. Where should I be defining them?

To the points in the first answer and comments, they sound good, but nothing works for me. I have an SQS Source that get's its connection via:

return AmazonSQSAsyncClientBuilder.standard()
    .withRegion(Regions.US_WEST_2.getName()))
    .build();

When I deploy to a Minikube environment, I edit the sqs app's deployment and set the AWS credentials in the env section. Then it works. For a local deployment, I've now tried:

stream deploy --name greg1 --properties "deployer.sqs.AWS_ACCESS_KEY_ID=<id>,deployer.sqs.AWS_SECRET_ACCESS_KEY=<secret>"

stream deploy --name greg1 --properties "deployer.sqs.aws_access_key_id=<id>,deployer.sqs.aws_secret_access_key=<secret>"

stream deploy --name greg1 --properties "app.sqs.AWS_ACCESS_KEY_ID=<id>,app.sqs.AWS_SECRET_ACCESS_KEY=<secret>"

stream deploy --name greg1 --properties "app.sqs.aws_access_key_id=<id>,app.sqs.aws_secret_access_key=<secret>"

All fail with the error message I get when credentials are wrong, which is, "The specified queue does not exist for this wsdl version." I've read the links, and don't really see anything else to try. Where am I going wrong?

回答1:

You can pass environment variables to the apps that are deployed via SCDF using application properties or deployment properties. Check the docs for a description of each type.

For example:

dataflow:> stream deploy --name ticktock --properties "deployer.time.local.javaOpts=-Xmx2048m -Dtest=foo"
