  • Optimal JMX Exposure Strategy for Kubernetes Multi-Node Architecture
    2 projects | dev.to | 27 Mar 2024
    Leverage a service mesh like Istio or Linkerd to manage communication between microservices within the Kubernetes cluster. These service meshes can be configured to intercept JMX traffic and enforce access control policies. Benefits:
  • Linkerd no longer shipping open source, stable releases

    Looks like CNCF waved them through Graduation anyway, let's look at policies from July 28, 2021 when they were deemed "Graduated"

    All maintainers of the LinkerD project had @boyant.io email addresses. [0] They do list 4 other members of a "Steering Committee", but LinkerD's GOVERNANCE.md gives all of the power to maintainers: [1]

    > Ideally, all project decisions are resolved by maintainer consensus. If this is not possible, maintainers may call a vote. The voting process is a simple majority in which each maintainer receives one vote.

    And CNCF Graduation policy says a project must "Have committers from at least two organizations" [2]. So it appears that the CNCF accepted the "Steering Committee" as an acceptable 2nd committer, even though the Governance policy still gave the maintainers all of the power.

    I would like to know if the Steering Committee voted to remove stable releases from an un-biased position acting in the best interest of the project, or if they were simply ignored or not even advised on the decision.

    I'm all for Boyant doing what they need to do to make money and survive as a Company. But at that point my opinion is that they should withdraw the project from the CNCF and stop pretending like the foundation has any influence on the project's governance.

  • Ultimate EKS Baseline Cluster: Part 1 - Provision EKS
    17 projects | dev.to | 21 Jul 2023
    From here, we can explore other developments and tutorials on Kubernetes, such as o11y or observability (PLG, ELK, ELF, TICK, Jaeger, Pyroscope), service mesh (Linkerd, Istio, NSM, Consul Connect, Cillium), and progressive delivery (ArgoCD, FluxCD, Spinnaker).
  • Istio moved to CNCF Graduation stage
    13 projects | news.ycombinator.com | 12 Jul 2023
    https://linkerd.io/ is a much lighter-weight alternative but you do still get some of the fancy things like mtls without needing any manual configuration. Install it, label your namespaces, and let it do it's thing!
  • API release strategies with API Gateway
    5 projects | dev.to | 22 Dec 2022
    Open source API Gateway (Apache APISIX and Traefik), Service Mesh (Istio and Linkerd) solutions are capable of doing traffic splitting and implementing functionalities like Canary Release and Blue-Green deployment. With canary testing, you can make a critical examination of a new release of an API by selecting only a small portion of your user base. We will cover the canary release next section.
  • GKE with Consul Service Mesh
    29 projects | dev.to | 3 Dec 2022
    I have experimented with other service meshes and I was able to get up to speed quickly: Linkerd = 1 day, Istio = 3 days, NGINX Service Mesh = 5 days, but Consul Connect service mesh took at least 11 days to get off the ground. This is by far the most complex solution available.

  • Top Terraform Tools to Know in 2024
    19 projects | dev.to | 26 Mar 2024
    A popular Policy-as-Code tool for Terraform is OPA, everyone's favorite versatile open-source policy engine that enforces security and compliance policies across your cloud-native stack, making it easier to manage and maintain consistent policy enforcement in complex, multi-service environments.

    Harness Policy As Code uses Open Policy Agent (OPA) as the central service to store and enforce policies for the different entities and processes across the Harness platform. In this section, you will define a policy that will deny a pipeline execution if there is no approval step defined in a deployment stage.

    OPA: While OPA is an open-source, general-purpose policy engine capable of enforcing unified and context-aware policies throughout the stack, it can also accept and output data in formats such as JSON, effectively functioning as a tool for generating or modifying configurations. Although it does not provide out-of-the-box schema definition support, it allows the integration of JsonSchema definitions.
  • Securing CI/CD Images with Cosign and OPA
    4 projects | dev.to | 15 Nov 2023
    In essence, container image signing involves adding a digital stamp to an image, affirming its authenticity. This digital assurance guarantees that the image is unchanged from creation to deployment. In this blog, I'll explain how to sign container images for Kubernetes using Cosign and the Open Policy Agent. I will also share a tutorial that demonstrates these concepts.

  • CIAM vs. IAM: What's the difference (2022)
    2 projects | news.ycombinator.com | 11 May 2023
    CIAM is not nearly as popular of a term as it needs to be. When most developers build apps today, they still look at their cloud provider's IAM or Active Directory for inspiration in design of their customer-facing systems. I think this article is actually understating the complexity. Conway's Law rules all and sometimes your systems and users won't even necessarily be in your control. I urge folks to look into policy engines like OPA[0] and ReBAC systems like SpiceDB[1] rather than reinventing the wrong wheel.

  • You Broke Reddit: The Pi-Day Outage
    3 projects | /r/RedditEng | 21 Mar 2023
    At this point, someone spotted that we were getting a lot of timeouts in the API server logs for write operations. But not specifically on the writes themselves. Rather, it was timeouts calling the admission controllers on the cluster. Reddit utilizes several different admission controller webhooks. On this cluster in particular, the only admission controller we use that’s generalized to watch all resources is Open Policy Agent (OPA). Since it was down anyway, we took this opportunity to delete its webhook configurations. The timeouts disappeared instantly… But the cluster didn’t recover.
