Java does not work with DOCKER_LAMBDA_USE_STDIN #143

Closed deecewan closed 5 years ago

deecewan commented 5 years ago

Running the java example (examples/java) with DOCKER_LAMBDA_USE_STDIN set results in an error:

Failed to load awslambda shared library: Library=libawslambda.so Exception=java.lang.ExceptionInInitializerError message=null

You can reproduce with:

echo '{"some": "event"}' | docker run --rm -e DOCKER_LAMBDA_USE_STDIN=1 -v "$PWD/build/docker":/var/task lambci/lambda:java8 org.lambci.lambda.ExampleHandler

after running gradle build

You're missing the -i flag to docker run
