SonarQube Analysis With Ginkgo on Mac

,

Ginkgo is the testing framework of choice for many projects developed in Golang. Here is an example setup for SonarQube project analysis.

Prerequisites

  • SonarQube server installation: For the purpose of the tutorial I have a docker image running on my machine on http://localhost:9000.
  • SonarQube project: For the purpose of the tutorial I have created a project with project key com.bdpanajotova.golang-sonar-example and name Golang Sonar Example.
  • Golang project for analysis with Ginkgo tests: Here is the example project I use in GitHub.

Here is the documentation for the fast local setup of SonarQube.

Pass a Parameter to All JVMs in A Machine at The Same Time

,

JAVA_TOOL_OPTIONS

Imagine a scenario where you need to change a JVM parameter, but you can’t or is not a good solution to changing the start script of your server(s).

One of the challenges we had, when we were working with containers, was a way to change a parameter to a JVM without building the docker image again.
The application at the start time should read a JVM parameter where a _user profile_was defined.
For specific reasons we sometimes need to change this profile, for instance, to use a more controlled user where we can debug an issue. In these situations, we want to stop the container/pod, change the profile and start again, or even start a different container with a different profile.

Getting Started With Container Registries

,

Container registries serve as libraries to store and access third-party container images required during the build phase of the SDLC and the images produced for deployment to test, staging, and production environments. While public container registries are accessible and convenient, private registries can better integrate into existing CI/CD workflows, offer greater control over access and security, as well as help ensure build repeatability and reliability. This Refcard covers key container concepts and terminology; common use cases; and guidelines for container registry configuration, operation, security, and storage.

How to Reduce Docker Image Size

,

If there are top ten buzzwords in the technology industry in the year 2019, the container is sure to be one of them. With the popularity of Docker, more and more scenarios are using Docker in the front-end field. This article shows how do we use Docker in the visualization interface of Nebula Graph, a distributed open-source graph database.

Why Using Docker

Docker is widely used in daily front-end development. Nebula Graph Studio (A visualization tool for Nebula Graph) uses Docker based on the following considerations:
