Fix issues with Docker build problem
Had this problem:
$ docker build -t my-container-name . [+] Building 0.3s (3/3) FINISHED => [internal] load build definition from Dockerfile 0.0s => => transferring dockerfile: 37B 0.0s => [internal] load .dockerignore 0.0s => => transferring context: 2B 0.0s => ERROR [internal] load metadata for public.ecr.aws/lambda/python:3.8 0.1s ------ > [internal] load metadata for public.ecr.aws/lambda/python:3.8: ------ failed to solve with frontend dockerfile.v0: failed to create LLB definition: unexpected status code [manifests 3.8]: 400 Bad Request
Based on this answer: https://stackoverflow.com/a/66993669/102401
I figured I'd troubleshoot with this:
DOCKER_BUILDKIT=0 docker build .
That command was successful and then I could run my original command and it worked. not sure what happened there, but that cleared whatever it was.
