runc features and specs

  • Standardization
    runc is part of the Open Containers Initiative (OCI), promoting standardization across container runtimes. This ensures interoperability and broad community support.
  • Lightweight
    As a lightweight and fast CLI tool, runc provides a minimal runtime for environments where resource efficiency is critical.
  • Security
    runc adheres to principles of secure software development and incorporates Linux kernel features like namespaces and cgroups to enhance security.
  • Broad Adoption
    As the reference implementation for OCI, runc is widely adopted and tested in production environments, ensuring reliability.
  • Flexibility
    runc offers the flexibility to handle low-level container configurations, making it suitable for advanced users needing granular control.

Possible disadvantages of runc

  • Complexity for Beginners
    The low-level nature of runc can be daunting for beginners who might prefer higher-level tools like Docker that abstract away complexities.
  • Minimalist Design
    While its simplicity is an advantage, runc lacks some of the advanced features and orchestration capabilities found in other container platforms.
  • Manual Configurations
    Users need to manually handle configurations, which can be error-prone and time-consuming compared to automated solutions.
  • Ecosystem Integration
    runc does not provide direct integration with tools and platforms by default, requiring additional setup for comprehensive ecosystem support.
  • Limited Features
    Compared to complete container platforms, runc offers fewer built-in features, requiring supplementary tools to achieve similar functionalities.

Composer features and specs

  • Dependency Management
    Composer allows for easy and efficient management of PHP dependencies, ensuring that the correct versions are used and conflicts are minimized.
  • Autoloading
    Composer supports autoloading, which means you don't have to manually include or require files, reducing boilerplate code.
  • Version Control
    It allows developers to specify and install the exact versions of the libraries they need, which helps in maintaining consistency across different environments.
  • Community Support
    Composer has a vast and active community, resulting in a plethora of libraries and packages readily available for use.
  • PSR Compliance
    Composer adheres to PHP-FIG PSR standards, promoting best practices and interoperability among PHP projects.
  • Custom Repositories
    Ability to use custom repositories allows for flexibility, enabling enterprises to create their own repository for internal use.

Possible disadvantages of Composer

  • Learning Curve
    Beginners may find Composer overwhelming due to its command-line interface and the complexity of managing dependencies.
  • Performance
    Installing or updating packages can sometimes be slow, particularly for projects with many dependencies.
  • Dependency Conflicts
    While Composer aims to minimize conflicts, complex projects can still face issues with dependency resolution that require manual intervention.
  • File Size
    Projects using Composer can lead to increased file sizes due to the inclusion of multiple libraries and their dependencies.
  • Security
    Including third-party packages can expose a project to potential security vulnerabilities if those packages are not well-maintained or audited.

  • Comparing 3 Docker container runtimes - Runc, gVisor and Kata Containers
    Previously I wrote about the multiple variants of Docker and also the dependencies behind the Docker daemon. One of the dependencies was the container runtime called runc. That is what creates the usual containers we are all familiar with. When you use Docker, this is the default runtime, which is understandable since it was started by Docker, Inc. - Source: dev.to / 7 months ago
  • You run containers, not dockers - Discussing Docker variants, components and versioning
    Now we have dockerd which uses containerd, but containerd will not create containers directly. It needs a runtime and the default runtime is runc, but that can be changed. Containerd actually doesn't have to know the parameters of the runtime. There is a shim process between containerd and runc, so containerd knows the parameters of the shim, and the shim knows the parameters of runc or other runtimes. - Source: dev.to / 7 months ago
  • US Cybersecurity: The Urgent Need for Memory Safety in Software Products
    It's interesting that, in light of things like this, you still see large software companies adding support for new components written in non-memory safe languages (e.g. C) As an example Red Hat OpenShift added support for crun(https://github.com/containers/crun), which is written in C as an alternative to runc, which is written in Go( - Source: Hacker News / over 1 year ago
  • Why did the Krustlet project die?
    Yeah, runtimeClass lets you specify which CRI plugin you want based on what you have available. Here's an example from the containerd documentation - you could have one node that can run containers under standard runc, gvisor, kata containers, or WASM. Without runtimeClass, you'd need either some form of custom solution or four differently configured nodes to run those different runtimes. That's how krustlet did... Source: over 2 years ago

  • Arguments a customer can understand not to use WordPress
    There is also no requirement to follow the PHP-FIG standards. The best thing that is build because of those standards is Composer. The most plugins I downloaded while writing use composer. The problem is that the plugins ship with their own vendor directory. While the standard is to have one vendor directory for the whole project. This results in different packages with the same or different version of it in the... - Source: dev.to / 24 days ago

    Composer and Packagist have become key tools for establishing the foundations of PHP-based applications. Packagist is essentially a directory containing PHP code out of which Composer, a PHP-dependency manager, retrieves packages.
