I'm using 2.7.0-RC1 Spring Cloud Data Flow on kubernetes. Although we pass an argument --logging.level.org.springframework.cloud.deployer.spi.local=DEBUG to SCDF run command, I'm still viewing INFO level bug.
How can we change log level to DEBUG?
The logging.level.org.springframework.cloud.deployer.spi.local flag is to set the log level of the local-deployer. Your deployer is on Kubernetes.
From the Spring Cloud Dataflow docs in the section Deployment Logs, there are equivalent settings available for other deployers. Refer this section:
Similar to the local-deployer and cloudfoundry-deployer options as discussed above, there are equivalent settings available for Apache YARN, Apache Mesos and Kubernetes variants, too. Check out the respective SPI implementations to find out more details about the packages to configure for logging.
Since you are deploying on Kubernetes, if you want to view the deployment logs, try this flag (note: I have not tested this):
--logging.level.org.springframework.cloud.deployer.spi.kubernetes=DEBUG
Your question does not specify if you want to view the deployer logs, or the application/stream logs. If you want to view the streaming application logs refer this link on Application Logs.
