  • Why is the principle stating that "interfaces should belong to the package that uses values of the interface type, not the package that implements those values" sometimes violated?
    2 projects | | 19 Feb 2023
    While exploring popular projects such as etcd and especially traefik, I noticed a violation of the principle that states "interfaces should belong to the package that uses values of the interface type, not the package that implements those values." For example, Here we can see that ManagerFactory import Registry interface that placed here and implementations of this interface in the same package, which violates the aforementioned principle. Even if the interface is simply a specification, it should still be defined on the consumer side. Is it considered bad practice to follow what traefik does in this case or I doesn't understand somthing? P.S. I'm newcomer, so sorry if it's silly question.
  • How to implement a distributed /etc directory using etcd and JuiceFS

    In case of data sensitivity, you can enable the encrypted communication function of etcd for encrypted data transmission. Refer to the sample script provided by the etcd project.
  • How to get a head start into contributing to open source projects
    3 projects | | 30 Jan 2023
    Step 0: You have a strong grasp on who uses the tool/product/service and for what purpose. That can take weeks, months, or years depending on the specific project you're contributing to. A little NodeJS module? Probably closer to days. etcd? Probably closer to months/years.

    etcd is not secure - etcd is where Kubernetes secrets are stored. Though etcd is a distributed key/value store with great performance, it lacks key features when it comes to handling sensitive data such as audit log, key rotation, and encryption of key.

    Yes, Kubernetes, in fact, relies on a number of other free and open source software packages. As a base, it relies on the Docker container runtime and the CoreOS Linux distribution, and it utilizes other open source projects for a number of its components, such as etcd for distributed key-value storage. The tool's core and control plane are both built in GO programming language, making it a completely Go-based application. Kubernetes itself is an open source project and has been used as a building block for other open source projects.

    Next, review deployment complexity such as DB-less versus database-backed deployments. For example, Kong does require running Cassandra or Postgres. Apigee requires Cassandra, Zookeeper, and Postgres to run, while other solutions like Express Gateway and Tyk only require Redis. Apache APISIX uses etcd as its data store, it stores and manages routing-related and plugin-related configurations in etcd in the Data Plane.
