  • Config as code — am I doing it wrong?
    4 projects | | 15 Mar 2022
    You can project along these lines to find the intersection, at which a change in configuration is just another effect to manage, and realize that, if you use a configuration representation that supports some sort of publish-and-subscribe "watching" system—like, say, the filesystem in Java since Java 7, or pretty much every key/value store since the early 2000s—you can write a purely functional configuration system that supports multiple kinds of representations, including distributed ones like Zookeeper, and propagates configuration changes via streams without the need to even restart the system.

  • 3 ways to deploy Apache APISIX on AWS (Part 1: AWS EC2)
    6 projects | | 27 Jun 2022
    APISIX uses etcd to save and synchronize configuration. Before installing APISIX, you need to install etcd on your machine. It would be installed automatically if you choose the Apache APISIX Docker compose mode, you will learn more about on the next blog post Use Docker Compose to deploy containerized APISIX to AWS ECS.
  • ECS Container map dns names
    2 projects | | 19 Jun 2022
    Since all of your apps are in the same environment, one possibility is to use a service registry like Consul or etcd. As a container comes up it registers itself by making a REST call to declare “I’m the Rabbit server!”. Then other apps call out to etcd with a REST query to ask “Where’s the Rabbit server?” and get the name of the Rabbit container. If you decide to start playing with HA or clustering, this can be extended so the service registry returns the name of the current primary node, or spreads traffic across multiple nodes by returning different responses based on rules you set up.
  • Kubernetes Admission Controllers: What They Are and Why They Matter
    2 projects | | 16 Jun 2022
    As mentioned earlier, admission controllers intercept API server requests before they’re executed or persisted in etcd. This makes them a perfect contender to apply security measures to help organizations meet policy requirements. Admission controllers can improve the security of Kubernetes workloads through a built-in PodSecurityPolicy (PSP), which mounts the root file system as read-only and prevents the containers from running as the root user.

  • Apache ShardingSphere Enterprise Applications — Bilibili
    4 projects | | 9 Jun 2022
    In cluster mode, Apache ShardingSphere integrates third-party registry components ZooKeeper and Etcd to achieve metadata and configuration sharing in the cluster environment. At the same time, with the help of the notification and coordination ability of the registry, it ensures the real-time synchronization of the cluster when the shared data changes. And the business will not be aware of changes from the registry.

    At your own pace, jump into orchestration using a Kubernetes distribution out there; but really, only do that fairly late in the game (e.g. OpenShift). Sadly, it's quite a jump from containers to orchestration, and there is no "smooth" in-between. Maybe as a prelude, you can look into etcd configuration clusters and Ceph storage clusters first, e.g. using a bunch of VMs on your machine, or a few Raspberry Pis. There are plenty of occasions to pinch your fingers with those, and thus valuable lessons to be learned :-)
  • HelloTalk: Leveraging Apache APISIX and OpenResty
    4 projects | | 5 Apr 2022
    Apache APISIX is a dynamic, real-time, high-performance API gateway. It offers traffic management features such as load balancing, dynamic upstream, canary release, service meltdown, authentication, observability, and other rich traffic management features. It’s built atop the Nginx reverse proxy server and the key-value store etcd, to provide a lightweight gateway.
