/var/runtime/bootstrap: Permission Denied

[mattBrzezinski]

I was attempting to modify this repo for an internal project, and ran into this issue. I then decided to just build and push up master here. When I attempt to test run the Lambda function on AWS I get the error:

I've tried to do a chmod +x bootstrap after this in the Dockerfile. Same result 😕.

It seems that creating this bootstrap file which does a cd /var/task and runs you script is the correct thing to do according to the documentation.

Modifying the source a bit. The result of ls -la /var/runtime/bootstrap

I added a Pull-request fixing this in the dockerfile (#4). Please noe that this would need to run docker build with the DOCKER_BUILDKIT=1 flag since chmod-ing something is a feature that requires BUILDKIT enabled (see eg here).

I'm not able to see this problem with my test today... I was able to run it properly from AWS without doing any chmod.

When I check out the repo, the bootstrap file already has permission 0775. I think the COPY command should have carried over the executable flag. Right?
