Capsule vs Docker: What are the differences?

## Key Differences between Capsule and Docker

Capsule and Docker are both containerization platforms; however, they have distinct differences that cater to different user needs. Here are key differences between Capsule and Docker:

1. **Architecture**:
    Capsule uses the concept of "Capsule" as its unit of encapsulation, allowing users to package applications and their dependencies in a single entity. On the other hand, Docker utilizes containers as the unit of deployment, which includes the application and all its dependencies.

2. **Isolation**:
    In Capsule, containers are isolated inside Capsules, providing an additional layer of separation between applications. Docker, on the other hand, uses containerization to achieve isolation, ensuring that each container runs in its own isolated environment.

3. **Portability**:
    Capsule focuses on portability by making it easy to move Capsules across different infrastructures and environments. Docker also emphasizes portability, allowing containers to run consistently on any Linux machine.

4. **Management**:
    Capsule streamlines management by simplifying the process of packaging and deploying applications into Capsules. Docker provides a more robust management system with features like Docker Swarm for orchestrating multiple containers.

5. **User Interface**:
    Capsule offers a straightforward user interface that is easy to use, especially for beginners. Docker provides a more comprehensive user interface with detailed controls and settings for advanced users.

6. **Community Support**:
    The community support for Capsule is still growing, with a focus on expanding its user base and improving documentation. Docker, being more established, has a large and active community that provides extensive resources, support, and add-ons.

In Summary, Capsule and Docker have key differences in architecture, isolation, portability, management, user interface, and community support, catering to different user needs in the realm of containerization platforms.

Advice on Docker, Capsule

Decided

lxd/lxc and Docker aren't congruent so this comparison needs a more detailed look; but in short I can say: the lxd-integrated administration of storage including zfs with its snapshot capabilities as well as the system container (multi-process) approach of lxc vs. the limited single-process container approach of Docker is the main reason I chose lxd over Docker.

Detailed Comparison

Docker	Capsule
The Docker Platform is the industry-leading container platform for continuous, high-velocity innovation, enabling organizations to seamlessly build and share any application — from legacy to what comes next — and securely run them anywhere	Packages any JVM application, no matter how complex, as a single, plain executable JAR. A capsule may directly contain all of the application’s dependencies or simply declare some or all of them, to be downloaded when launched.

What are some alternatives to Docker, Capsule?

Apache Maven

Maven allows a project to build using its project object model (POM) and a set of plugins that are shared by all projects using Maven, providing a uniform build system. Once you familiarize yourself with how one Maven project builds you automatically know how all Maven projects build saving you immense amounts of time when trying to navigate many projects.

Gradle

Gradle is a build tool with a focus on build automation and support for multi-language development. If you are building, testing, publishing, and deploying software on any platform, Gradle offers a flexible model that can support the entire development lifecycle from compiling and packaging code to publishing web sites.

Bazel

Bazel is a build tool that builds code quickly and reliably. It is used to build the majority of Google's software, and thus it has been designed to handle build problems present in Google's development environment.

LXD

LXD isn't a rewrite of LXC, in fact it's building on top of LXC to provide a new, better user experience. Under the hood, LXD uses LXC through liblxc and its Go binding to create and manage the containers. It's basically an alternative to LXC's tools and distribution template system with the added features that come from being controllable over the network.

Pants

Pants is a build system for Java, Scala and Python. It works particularly well for a source code repository that contains many distinct projects.

LXC

LXC is a userspace interface for the Linux kernel containment features. Through a powerful API and simple tools, it lets Linux users easily create and manage system or application containers.

JitPack

JitPack is an easy to use package repository for Gradle/Sbt and Maven projects. We build GitHub projects on demand and provides ready-to-use packages.

SBT

It is similar to Java's Maven and Ant. Its main features are: Native support for compiling Scala code and integrating with many Scala test frameworks.

rkt

Rocket is a cli for running App Containers. The goal of rocket is to be composable, secure, and fast.

Buck

Buck encourages the creation of small, reusable modules consisting of code and resources, and supports a variety of languages on many platforms.
