While testing my Lambda using a Docker container, when the Lambda is invoked, I’m getting this runtime error:
Process 17(bootstrap) exited: Runtime exited with error: exit status 127
Process exit status code 127 errors are usually a file not found error. Going back through the Lambda logs, luckily there’s an error telling me I have an error in my shell script:
/var/task/test.sh: line 5: output: command not found
Quick and easy fix.
I’m getting this error when invoking myLambda which is using a Docker container:
Init failed error=fork/exec /var/runtime/bootstrap
To fix this, add a step to make the bootstrap file executable after you copy into the image:
COPY bootstrap ${LAMBDA_RUNTIME_DIR}
RUN chmod +x ${LAMBDA_RUNTIME_DIR}/bootstrap
When running a ‘docker build . -t imagename’ to build a new image, each of the steps in your Dockerfile outputs a one-line status, but if you need to see the actual output of each step, you need pass the –progress-plain option. If your build is stopping at a particular step and you need to see the output of previous steps that are now cached, you can use the –no-cache option:
docker build --progress=plain --no-cache . -t imagename
I’m configuring an AWS Lambda with a custom runtime using the Serverless framework, and I’ve run into this error:
Architecture config by default on Lambda is showing x86_64::
If I trying to create with arm64 instead it gives:
An error occurred: HelloLambdaFunction - Resource handler returned message: "Runtime provided does not support the following architectures [arm64]. Please select different architectures from [x86_64] or select a different runtime
This is slightly obscure and it a result of the ‘provided’ runtime coming in 2 flavors, Amazon Linux 1 (provided) and Amazon Linux 2 (provided.al2), and only provided.al2 supports arm64.
If you change your serverless.yaml to include the provided.al2 runtime, then it deploys as expected.
This just means replacing this:
provider: name: aws runtime: provided
with:
provider: name: aws runtime: provided.al2
Note now how the runtime shows Amazon Linux 2 and arm64:
