How K8s CPU Requests and Limits Actually Work — Chapter 2

To pick up again, imagine that in your Kubernetes pod spec, you asked for 250 millicores of CPU to run your container.
Something has to happen to turn that abstract request, 250m of CPU, along with any limits, into a set of concrete allocations or constraints around a running process.
Most Kubernetes resource abstractions are implemented by kubelet, and the container runtime, using Linux Control Groups (cgroups) and control group settings.
When Kubernetes sets cpu.max (limits), that doesn’t change the process’s proportional priority while it’s runnable.
There is often moment-to-moment spare CPU capacity on a node that isn’t guaranteed to a particular container by virtue of its CPU requests.
The limits approach can feel tempting at first, but an industry consensus has been building around not using CPU limits at all for general-purpose workload templates and instead relying on the request method.
People usually intuit that limits are related to fairness and make sure every workload gets its allotted time.
With CPU and CFS cgroup settings out of the way, it’s time to move on to memory.
How do memory requests and limits translate to Linux process settings?
Will proportionality modeling apply to memory the same way it does to CPU?

SSDLC: 7 Steps to Create a Secure Software Supply Chain

Adopting SSDLC in software development ensures security controls and risk management are integrated throughout the development phases.
The practice of SSDLC can help create resilient software to internal and external threats, lowering the possibility of expensive vulnerabilities later in the software's lifecycle.
Dependency sprawl, visibility gaps, slow response times, and zero-day vulnerabilities are notable challenges faced when building a secure software supply chain.
Define security requirements, perform threat modeling, map features to requirements, automate vulnerability detection in third-party dependencies, integrate security checks into CI/CD pipelines, monitor supply chain components for emerging vulnerabilities and conduct contextual risk analysis are the seven steps to developing a secure software supply chain.
Automated checks facilitate maintaining a consistent security posture across different environments, whereas monitoring tools can automate notifications for updates and security patches in real-time.
Contextual risk analysis allows companies to prioritize their security efforts more effectively by assessing the reachability, criticality and potential impact of the vulnerabilities associated with their specific dependencies based on their unique environments.
SSDLC best practices are critical to allow companies not to compromise on security and integrity while increasing their efficiency.
Myrror offers comprehensive software supply chain risk analysis, identifying vulnerabilities and security gaps and offering detailed remediation guidance tailored to specific environments.
By approaching software development through the lens of SSDLC and tools like Myrror, organizations can be proactive, identify vulnerabilities early and secure their software supply chains against internal or external libraries and services.

A Comprehensive Guide to Dockerfile Creation with Explanation of Key Commands

Dockerfiles are essential for creating Docker images, which serve as the foundation for containers.
The FROM instruction sets the base image for your Docker image.
The RUN command is used to execute commands inside the image during the build process.
The LABEL instruction adds metadata to an image in the form of key-value pairs.
The ADD command is used to copy files from your host machine into the container.
COPY works similarly to ADD, but it doesn't have the extra functionality and is considered more predictable.
The VOLUME command creates a mount point for volumes, which can be used to persist data in a container or share data between containers.
The EXPOSE command informs Docker that the container will listen on specific ports at runtime.
WORKDIR sets the working directory for subsequent instructions like RUN, CMD, ENTRYPOINT, COPY, etc.
The USER command sets the user and group to use when running commands inside the container.
