QUESTION
I implement AWS Lambda function on Java using AWS Java SDK and AWS Lambda Java Support Libraries and in some cases I need to get name, version and alias of current function right in code of the function.
Name and version I can get from Context using getFunctionName() and getFunctionVersion() methods. But how can I get current alias value?
...ANSWER
Answered 2018-May-03 at 18:32You can use the Context
object passed into the lambda handler to get that data.
https://docs.aws.amazon.com/lambda/latest/dg/java-context-object.html
The context object properties are:
getMemoryLimitInMB(): Memory limit, in MB, you configured for the Lambda function.
getFunctionName(): Name of the Lambda function that is running.
getFunctionVersion(): The Lambda function version that is executing. If an alias is used to invoke the function, then getFunctionVersion will be the version the alias points to.
getInvokedFunctionArn(): The ARN used to invoke this function. It can be function ARN or alias ARN. An unqualified ARN executes the $LATEST version and aliases execute the function version it is pointing to.
