Debugging microservices applications is a difficult task. The state of an application is spread across multiple processes, often on different nodes. It is hard to get the holistic view of an application's state. Certain tools exist for troubleshooting microservice issues. OpenTracing can be used to produce transaction or workflow logs for post-mortem analysis. Service meshes like Istio can be used to monitor the network to identify latency problems. Unfortunately, these tools are passive, the feedback loop is slow, and they do not allow you to monitor and alter the application during run time.
 
Squash brings the power of modern debuggers to developers of microservice apps. Squash bridges between the apps running in a Kubernetes environment (without modifying them) and the IDE. Users are free to choose which containers, pods, services or images they are interested in debugging, and are allowed to set breakpoints in their codes, follow values of their variables on the fly, step through the code while jumping between microservices, and change these values during run time.

Moby is an open-source project created by Docker to advance the software containerization movement. It provides a “Lego set” of dozens of components, the framework for assembling them into custom container-based systems, and a place for all container enthusiasts to experiment and exchange ideas.
 
It provides a library of containerized components for all vital aspects of a container system: OS, container runtime, orchestration, infrastructure management, networking, storage, security, build, image distribution, etc. It also provides tools to assemble the components into runnable artifacts for a variety of platforms and architectures: bare metal (both x86 and Arm); executables for Linux, Mac and Windows; VM images for popular cloud and virtualization providers.

Docker is an open-source engine that automates the deployment of any application as a lightweight, portable, self-sufficient container that will run virtually anywhere. Common use cases for Docker include Automating the packaging and deployment of applications, Creation of lightweight, private PAAS environments,   Automated testing and continuous integration/deployment, Deploying and scaling web apps, databases and backend services

Buildah - a tool that facilitates building Open Container Initiative (OCI) container images. The Buildah package provides a command line tool that can be used to Create a working container, either from scratch or using an image, Images can be built in either the OCI image format or the traditional upstream docker image format, Mount / Unmount / Delete / Rename the container.

kaniko is a tool to build container images from a Dockerfile, inside a container or Kubernetes cluster. kaniko doesn't depend on a Docker daemon and executes each command within a Dockerfile completely in userspace. This enables building container images in environments that can't easily or securely run a Docker daemon, such as a standard Kubernetes cluster.

Packer is a tool for building identical machine images for multiple platforms from a single source configuration. Packer comes out of the box with support for the following platforms Amazon EC2, DigitalOcean, Docker, Google Compute Engine, 
OpenStack, Parallels, QEMU, VirtualBox, VMware.

skopeo is a command line utility that performs various operations on container images and image repositories. skopeo can work with OCI images as well as the original Docker v2 images. Skopeo works with API V2 container image registries such as docker.io and quay.io registries, private registries, local directories and local OCI-layout directories. 
 
skopeo can perform operations which consist of:
<ul>
<li>Copying an image from and to various storage mechanisms.
For example you can copy images from one registry to another, without requiring privilege.</li>
<li>Inspecting a remote image showing its properties including its layers, without requiring you to pull the image to the host.</li>
<li>Deleting an image from an image repository.</li>
<li>Syncing an external image repository to an internal registry for air-gapped deployments.</li>
<li>When required by the repository, skopeo can pass the appropriate credentials and certificates for authentication.</li>
</ul>

containerd is an industry-standard container runtime with an emphasis on simplicity, robustness and portability. It is available as a daemon for Linux and Windows, which can manage the complete container lifecycle of its host system: image transfer and storage, container execution and supervision, low-level storage and network attachments, etc.. containerd is designed to be embedded into a larger system, rather than being used directly by developers or end-users.

Podman (the POD MANager) is a tool for managing containers and images, volumes mounted into those containers, and pods made from groups of containers. Podman is based on libpod, a library for container lifecycle management that is also contained in this repository. The libpod library provides APIs for managing containers, pods, container images, and volumes.

Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions. Using the concepts of "labels" and "pods", it groups the containers which make up an application into logical units for easy management and discovery.
