问题
I'm using the cf CLI to deploy a spring boot application to Bluemix. I'm getting an error 'RSA premaster secret error' as can be seen here: RSA premaster secret error when using webHDFS from BigInsights on cloud
I'm deploying my application like this:
# Create a Liberty application in Blumemix.
# Set APPNAME (below) to the name of the application.
APPNAME=<<theappname>>
cf login -u cf_username -p cf_password
cf push $APPNAME -p build/libs/myapp.jar
It seems that I need to add a certificate to the truststore - what are the additional steps for doing this? From what I can tell I need to repackage the liberty server to do this.
The above code snippet encapsulates my entire knowledge about liberty, please take that into account when providing an answer. For instance, I have seen some answers suggesting that I need to edit server.xml, but I don't have this file, so presumably I need to create it from scratch, or generate it some how?
I have seen similar questions, but the workflow I'm specifically asking about to add a certificate is when I'm using the cf CLI tools.

There's no one thing to do to accomplish this task, it will require several steps:
1) Ensure Liberty & Spring app works locally. The data below will guide you through ensuring Liberty & Spring are setup correctly:
