• Dockerizing Hugo Sites

    Hugo is a great OSS project that can be used to create static sites that are based on markdown files stored in a git repository. My personal blog is created using hugo and hosted on AWS S3. I recently did some work to dockerize it and thought I’d write about it. First thing I needed to do was create a docker image with hugo installed so I can build my hugo site.
  • Automatically get latest Docker security vulnerabilities posted to slack channel

    It’s extremely important to always be aware of all the announcements related to security issues for the products you use and support within your company, If you use slack we can have all these announcements posted directly to a slack channel. In this post, I will go over how we can do just that for Docker. Approach You can get a list of known security vulnerabilities using www.cvedetails.com website. Known security vulnerabilities can be searched by the vendor, product, version etc.
  • Configuration As Code With Docker and Spring Boot

    What is Configuration as code? Configuration as code is a DevOps practice that promotes storing of application configuration as code within source code repository. Few key benefits that this brings is that Versioning of application configuration By storing the application configuration in source code repository such as Git allows us to see what configuration changes were made over a period of time and who made those changes By using branches you can isolate changes that are under development without affecting the production application
  • Using docker for dynamically provisioning jenkins build slaves and running build jobs

    Why? In Many enterprises leveraging Jenkins for running automated builds, it’s quite common to have a central team providing Jenkins and other CI/CD tools as shared service. One of the issues that you quickly run into is that each development group within enterprise may have different platforms, frameworks, tools, libraries etc and to support the needs of everyone you end up provisioning jenkins build slaves for each group installing everything a particular group needs to be able to build/run jenkins jobs on these Jenkins slave nodes.
  • Jenkins Build Slave Image For Building Hugo Projects

    Overview At T-Mobile we are starting to leverage Hugo which is an OSS static site generator tool for a few marketing type of sites. We are also huge Jenkins shop and run jenkins build slaves in docker and Mesos/Marathon. We use S3 bucket for hosting content generated, cloudfront for global content delivery and route 53 for DNS. I’ve created a docker jenkins build slave image for building hugo projects in Jenkins.
  • Some thoughts on running docker registries in jFrog artifactory

    At T-Mobile we use jFrog artifactory as a centralized repository for storing artifacts. It is one of the key tools in our DevOps toolset and is integrated into our CI/CD processes. Artifactory has support for storing docker images in repositories, essentially its like running private docker registries. Artifactory lets you create multiple docker repositories which is pretty nice for a large company like T-Mobile where there are numerous groups developing dockerized microservices, each group can have thier own repository (registry in docker terminology) with right level of access control that governs who can push images into it.
