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.
Fly is a platform for applications that need to run globally. It runs your code close to users and scales compute in cities where your app is busiest.
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.
Dapr is a portable, serverless, event-driven runtime that makes it easy for developers to build resilient, stateless and stateful microservices that run on the cloud and edge and embraces the diversity of languages and developer frameworks.
Wasmer enables super lightweight containers based on WebAssembly that can run anywhere: from Desktop to the Cloud and IoT devices, and also embedded in any programming language.
Lightweight Kubernetes
Easy to install. A binary of less than 40 MB. Only 512 MB of RAM required to run.
Tilt makes it possible to develop all your microservices locally in Kubernetes while collaborating with your team.
Write a Tiltfile script that describes how your services fit together. Share it with your team so that any engineer can hack on any server. See a complete view of your system, from building to deploying to logging to crashing.
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.
Harbor is an open source cloud native registry that stores, signs, and scans container images for vulnerabilities.
Harbor solves common challenges by delivering trust, compliance, performance, and interoperability. It fills a gap for organizations and applications that cannot use a public or cloud-based registry, or want a consistent experience across clouds.
Jenkins X is a CI / CD platform for Kubernetes.
Skaffold is a command line tool that facilitates continuous development for Kubernetes applications. You can iterate on your application source code locally then deploy to local or remote Kubernetes clusters. Skaffold handles the workflow for building, pushing and deploying your application. It can also be used in an automated context such as a CI/CD pipeline to leverage the same workflow and tooling when moving applications to production.
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.
Helm helps you manage Kubernetes applications — Helm Charts helps you define, install, and upgrade even the most complex Kubernetes application.
Charts are easy to create, version, share, and publish — so start using Helm and stop the copy-and-paste madness.
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
