tc-sam-cli
A very simplified tool wrapped around aws-sam-cli to deploy aws lambda.
Works together with tclambda

Generate AWS SAM template
After every change in tc-sam.toml
the template must be regenerated.
$ tc-sam generate_template > template.yml
It's recommended to have template.yml
under source control.
Every Lambda has given access to each other's SQS Queue, and all Lambdas share the same S3 bucket for results.
Deploy
Deploy is very straightforward, it builds the sam package and deploys the cloudformation stack.
$ tc-sam deploy
Environmental export
$ tc-sam env_export
TC_NUMPY_QUEUE="https://sqs.eu-west-1.amazonaws.com/123/tc-sam-playground-NumpySqs-ABC"
TC_NUMPY_BUCKET="tc-sam-playground-resultbucket-123456"
TC_MYLAMBDA_QUEUE="https://sqs.eu-west-1.amazonaws.com/123/tc-sam-playground-TcLambdaSqs-ABC"
TC_MYLAMBDA_BUCKET="tc-sam-playground-resultbucket-123456"
These settings can be copied to other projects that will use the aws lambdas.
Ping all lambdas
The tclambda handler comes with a ping
command to test if both permissions to SQS and S3 are allowed.
$ tc-sam ping
Ping NUMPY
Ping MYLAMBDA
