Tools for deploying to AWS via CloudFormation and Serverless framework that support a pull request based workflow

Project description

Nameless Deploy Tools

Build Status Coverage Status Code style: black

Released version 1.314

Nameless deploy tools are a set of tools to implement a true Infrastructure As Code workflow with various cloud infrastructure management tools. Currently supported tools are CloudFormation, AWS CDK, Serverless Framework, Terraform, Azure Resource Manager (with a YAML syntax) and Bicep.

Why Nameless?

A common analogy for cloud infrastructure has been to move from having pets with names that need lots of looking after, to cattle that has at most id's. It's time to move to the industrial age from the agrarian era. The infrastructure our applications runs now comes and goes, and we know at most some statistical information about the actual executions. Run times, memory usage, used bandwidth and the like. We no longer know even the id's of the things that actually run the code. Hence - nameless.


We at Nitor are software engineers with mostly a developer or architect background, but a lot of us have had to work closely with various Operations teams around the world. DevOps has a natural appeal to us and immediately "infrastructure as code" meant for us that we should apply the best development practices to infrastructure development. It starts with version control and continues with testing new features in isolation and a workflow that supports this. Our teams usually take into use a feature branch workflow if it is feasible, and we expect all the tools and practices to support this. For infrastructure this type of branching means that you should be able to spin up enough of the infrastructure to be able to verify the changes you want to implement in production. Also, the testing environment should be close enough to the target environment for the results to be valid. So the differences between testing and production environments should be minimized and reviewable.

With the popular tools like Ansible, Terraform, Chef etc. you need to come up with and implement the ways to achieve the goals above. As far as I know, no tool besides ndt has at its core a thought-out way of a branching infrastructure development model.

What it is

nameless-deploy-tools works by defining Amazon Machine Images, Docker containers, Serverless services and deploying CloudFormation stacks of resources. CloudFormation stacks can also be defined with AWS CDK applications. All of the above can also be deployed using Terraform.


pip install nameless-deploy-tools

Requires Python 3.7 or newer.

Getting started

To use nameless-deploy-tools you need to set up a project repository that describes the images you want to build, and the stacks you want to deploy them in. See ndt-project-template for an example.

Here are few commands you can use. All of these are run in your project repository root. You need to have AWS credentials for command line access set up.

  • To bake a new version of an image: ndt bake-image <image-name>
  • To build a new Docker container image ndt bake-docker <component> <docker-name>
  • To deploy a stack:
    • with a known AMI id: ndt deploy-stack <image-name> <stack-name> <AMI-id>
    • with the newest AMI id by a given bake job: ndt deploy-stack <image-name> <stack-name> "" <bake-job-name>
  • To undeploy a stack: ndt undeploy-stack <image-name> <stack-name>

For full list of commands see here

You can additionally use a faster register-complete by running ./ This compiles a C++ program from the file nameless-dt-register-complete.cpp, and replaces the Python version of nameless-dt-register-complete with it.



This library uses a simplified semantic versioning scheme: major version change for changes that are not backwards compatible (not expecting these) and the minor version for all backwards compatible changes. We won't make the distinction between new functionality and bugfixes, since we don't think it matters and is not a thing worth wasting time on. We will release often and if we need changes that are not comptatible, we will fork the next major version and release alphas versions of that until we are happy to release the next major version and try and have a painless upgrade path.


Python dependencies are specified in setup.cfg. pip-compile is used to generate the requirements.txt file. To update the requirements, use the following commands:

pip install --upgrade pip-tools

Code formatting and linting

This project uses Black together with isort for Python code formatting, and flake8 for linting. They are configured with a custom line length limit of 120.


pip install --upgrade black isort flake8
black .
isort .
flake8 .

These can also be integrated to IDEs / editors or run as a pre-commit hook. See the documentation for example for Black here. VS Code has built-in support for Black, isort, and flake8 through official plugins.

Using with pre-commit:

# setup to be run automatically on git commit
pre-commit install

# run manually
pre-commit run --all-files
