Testcontainers is an open source library for providing throwaway, lightweight instances of databases, message brokers, web browsers, or just about anything that can run in a Docker container.

A container-based solution for automating Docker container base image updates.

A vulnerability scanner for container images and filesystems.

Batect allows you to define your development tasks (building, running, testing, linting and more) in terms of one or more Docker containers, run those tasks quickly and consistently everywhere, and easily share them with your team.

A smarter Dockerfile linter that helps you build best practice Docker images. The linter is parsing the Dockerfile into an AST and performs rules on top of the AST. It additionally is using the famous Shellcheck to lint the Bash code inside RUN instructions.

Simple app development & deployment - into any Kubernetes cluster. Draft makes it easy to build applications that run on Kubernetes. Draft targets the "inner loop" of a developer's workflow: as they hack on code, but before code is committed to version control. Using two simple commands, developers can now begin hacking on container-based applications without requiring Docker or even installing Kubernetes themselves.

A tool for exploring a docker image, layer contents, and discovering ways to shrink your Docker image size.

Binci is a utility that allows you to easily containerize your development workflow using Docker. Simply put, it's like having a cleanroom for all of your development processes which contain services (like databases) without needing to setup and maintain these environments manually.

Datasette provides an instant, read-only JSON API for any SQLite database. It also provides tools for packaging the database up as a Docker container and deploying that container to hosting providers such as Zeit Now or Heroku.

Telepresence, in conjunction with a containerized development environment, gives the developer a fast development workflow in developing a multi-container application on Kubernetes. Telepresence lets you run a Docker container locally, while proxying it to your Kubernetes cluster.

Kitchen provides a test harness to execute infrastructure code on one or more platforms in isolation.

A driver plugin architecture is used to run code on various cloud providers and virtualization technologies such as Vagrant, Amazon EC2, and Docker. Read more

Many testing frameworks are supported out of the box including InSpec, Serverspec, and Bats

Gitkube is a tool for building and deploying docker images on Kubernetes using git push.

cAdvisor (Container Advisor) provides container users an understanding of the resource usage and performance characteristics of their running containers. It is a running daemon that collects, aggregates, processes, and exports information about running containers. Specifically, for each container it keeps resource isolation parameters, historical resource usage, histograms of complete historical resource usage and network statistics. This data is exported by container and machine-wide.

cAdvisor has native support for Docker containers and should support just about any other container type out of the box.

Dotmesh captures snapshots from stateful Docker and Kubernetes applications as ’datadots‘, and gives you the ability to label, store and share them as you would with version-controlled code. Dotmesh is an open–source primitive that can be accessed via CLI or API.

Run containers through a simple, yet powerful graphical user interface.

The Container Structure Tests provide a powerful framework to validate the structure of a container image. These tests can be used to check the output of commands in an image, as well as verify metadata and contents of the filesystem.

Best Practices for kubernetes

container-diff is a tool for analyzing and comparing container images. container-diff can examine images along several different criteria, including:

Docker Image History
Image file system
Apt packages
pip packages
npm packages
