Python¶

The AWS Construct Library packages is also available like a python package

pip search aws-cdk # for searching which module you want to load
pip install aws-cdk.aws-lambda # for installing AWS CDK Lambda module

In this sample, there are more modules because it will be also used a CI / CD system:

all modules are loaded and initialized on files named app.<something>.py
each app.py file uses a file named buildspec.yml for deploying the CD system by AWS CodePipeline

By shell¶

AWS CDK Toolkit is useful for initialization of the application,

cd cdk/python/
bash build.sh

For testing the application, you can check almost the template is correct

cd cdk/python/
python3 -m unittest discover -v

cd cdk/python/
export AWS_PROFILE=your-account
export STAGE=basic
cdk bootstrap
cdk deploy ${STAGE}

For deploying a Minetest server and a lambda function and more.

cd cdk/python/
export AWS_PROFILE=your-account
export STAGE=more
cdk deploy ${STAGE}

For deploying a Minetest server and a lambda function and what else you can manage.

cd cdk/python/
export AWS_PROFILE=your-account
export STAGE=plus
cdk deploy ${STAGE}

cd cdk/python/
export AWS_PROFILE=your-account
export STAGE=pipeline
cdk deploy ${STAGE}

For deleting,

cd cdk/python/
export AWS_PROFILE=your-account
cdk destroy ${STAGE}

An ad hoc script maybe it could be useful for a specific CI / CD system. Generally, it is not necessary.

In this example, you have a simple introduction of CI / CD system by CodePipeline.

The logic of your CI / CD system is defined on buildspec.yml file

the AWS simple pipeline package used, allows you to define your logic on buildspec.yml file
you can use many files, like the sample that you can find in aws-simple-pipeline, or nothing

You can also find

the build script, named build.sh, it is used during the CodeBuild step
the deploy script, named deploy.sh, it is used to differ which command run in each stage

These bash script files are prepared in your client before to test your CI / CD system: you have to be able to

build all packages that you use before to run cdk or unit test
deploy your AWS instances from your client before to test your CI / CD system

When you use AWS CDK,

now there is not an official testing infrastructure, but you can test your application on your client by AWS CDK test Synth package
you can manage all by code, so also a CI / CD system, like AWS simple pipeline used in this sample
