SkyDNS features and specs

  • Service Discovery
    SkyDNS provides a simple service discovery mechanism using DNS, which can be easily integrated into existing systems that rely on DNS for service location.
  • Integration with etcd
    SkyDNS integrates with etcd, a distributed key-value store, which makes it robust and reliable for dynamic service registration and can handle changes in the service environment efficiently.
  • Lightweight and Fast
    Being a lightweight service, SkyDNS can perform DNS queries rapidly without the overhead that comes with more complex systems.
  • Flexible Configuration
    SkyDNS allows for flexible configuration options, enabling custom setups tailored to specific organizational needs.

Possible disadvantages of SkyDNS

  • Limited Features
    Compared to more established DNS solutions, SkyDNS has relatively fewer features, which might not accommodate complex networking requirements.
  • Dependency on etcd
    The reliance on etcd can be a drawback for organizations not already using it, as they would need to deploy and manage an additional system.
  • Scalability Concerns
    While SkyDNS is suitable for small to medium-sized environments, its scalability can become an issue as the number of services and queries grows significantly.
  • Community Support
    Given that it's an open-source project, SkyDNS might not have the level of support or comprehensive documentation that commercial DNS solutions offer.

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.

  • 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
