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.

Flox features and specs

  • Reproducibility
    Flox provides a consistent and reproducible environment for developing and deploying software, ensuring that applications run the same way on different machines and platforms.
  • Ease of Use
    Flox simplifies the management of dependencies and environments, making it easier for developers to maintain their software setups.
  • Isolation
    Flox offers isolated environments which help in avoiding conflicts between different software packages and their dependencies.
  • Community Support
    As a growing platform, Flox benefits from an active community that contributes to its development and provides support to users.

Possible disadvantages of Flox

  • Learning Curve
    New users may find it challenging to get started with Flox due to its unique approach to package and environment management.
  • Limited Adoption
    As a relatively new tool, Flox might not have widespread adoption yet, meaning fewer integrations and less third-party support compared to more established solutions.
  • Complexity
    For simple projects or those not needing strict reproducibility, Flox might introduce unnecessary complexity.

  • 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 / 6 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 / 6 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

  • Go 1.24's go tool is one of the best additions to the ecosystem in years
    I think it's a bad addition since it pushes people towards a worse solution to a common problem. Using "go tool" forces you to have a bunch of dependencies in your go.mod that can conflict with your software's real dependency requirements, when there's zero reason those matter. You shouldn't have to care if one of your developer tools depends on a different version of a library than you. It makes it so the tools... - Source: Hacker News / 3 months ago
  • Nix – Death by a Thousand Cuts
    I think that's a bit reductive, but I get the intent. A lot of people see systemic problems in their development and turn to tools to reduce the cognitive load, busywork, or just otherwise automate a solution. For example "we always argue over formatting" -> use an automated formatter. That makes total sense as long as managing/interacting with the tool is less work, not just different work. With Nix I still think... - Source: Hacker News / 4 months ago
