vsbmeza/sam repository overview

Running AWS SAM requires a specific version of Python in perfect conditions. That's not always an option.

To have SAM work reliably on every machine, this package makes it available to run in docker. SAM however requires docker itself to operate, so there are a few caveats to this.

1. The container needs to be privileged (--privileged)
2. The container needs access to the docker sock (-v /var/run/docker.sock:/var/run/docker.sock)

⁠Environment Variables

• PORT - which port should SAM run on
• AWS_PROFILE - which AWS profile to use

⁠Mount Points

### /app This is where your template.yml should be, and all the code it needs to serve

⁠/root/.aws/credentials

This is where you can mount your ~/.aws/credentials, so the AWS_PROFILE environment parameter could be meaningful

⁠Examples

⁠Lambda + DynamoDB

Running in Docker Compose with Dynamo DB to locally test Lambda functions docker-compose.yml
