In order to build Docker images for Lambda functions with CDK on ARM or other non-Intel platforms, but want the Lambda to be on an x8664 platform, use the platform parameter…

Sometimes you won’t be able to run a Docker container because some .so file can’t be found. This is how to fix it:

Given a Dockerfile on an EC2 instance that has, at the very least, these commands at the end: EXPOSE 8888 ENTRYPOINT ["/bin/bash"]

First, build your image (assuming your Dockerfile is in the current directory): docker build -t myimg .

When using docker run, the –mount parameter allows you to specify a directory to recreate within the Docker container so that you can edit your code locally and then run it…

To use Docker for developing in VS Code, you can use the Docker, Dev Containers and Remote Explorer extensions. Here’s a rough step-by-step guide: 1. Build an image if it…

When deploying with CDK, I started out of nowhere getting this error: OSError: [Errno 18] Invalid cross-device link: ‘/tmp/pip-target-e4qns87/lib/python/numpy’ ->…

Unlike in AWS Lambda code, in Sagemaker training jobs using custom Python code in Docker containers logging won’t work unless a stream handler is specifically added to the logger.

At the end of a Dockerfile that defines a container for a Sagemaker training job, you have to define the SAGEMAKERPROGRAM environment variable. It needs to point directly to…

Redeploying a CDK stack with a Lambda function that relies on a Docker image in ECR won’t necessarily update the function with a newly pushed image. Instead, use the Lambda…
