Jenkins logoA few months ago, we worked with a client to migrate websites from on-premises to Azure. As part of this migration, Jenkins was set up to do the Continuous Integration/Continuous Delivery. During the initial setup, we checked out Jenkins email notifications and they were working fine with their internal mail server.

One fine day, an email comes from the client stating that emails from Jenkins were not coming at all. Well, that’s strange…

The Diagnosis

I like troubleshooting quite a lot and the rule of thumb is to first ask what changed? While the initial diagnosis was going on, the client mentioned that their network team made upgrades to the mail server and now only TLSv1.2 & TLSv1.1 were supported. Earlier, Jenkins sent email using SSL. (Yep, you guessed it right…using the -Dmail.smtp.starttls.enable=true parameter.) Read More…

In this video blog, I’ll walk you through building a continuous integration and continuous delivery (CI/CD) pipeline using the latest tools from Microsoft, including Visual Studio Team Services (VSTS) and Azure. The pipeline is built to support a .NET core application, and the walkthrough includes the following steps:

  1. Configuring Continuous Integration (CI) with VSTS Build services
  2. Adding unit testing and validation to the CI process
  3. Adding Continuous Deployment (CD) with VSTS Release Management & Azure PaaS
  4. Adding automated performance testing to the pipeline
  5. Promotion of the deployment to production once validated
  6. Sending feedback on completion of the process to Slack

These disciplines can play a significant role in building stable release processes that help ensure project milestones are met.

Continuous Integration (CI) and Continuous Delivery (DC) are rapidly becoming an integral part of software development. These disciplines can play a significant role in building stable release processes that help ensure project milestones are met. And in addition to simply performing compilation tasks, CI systems can be extended to execute unit testing, functional testing, UI testing, and many other tasks. This walkthrough demonstrates the creation of a simple CI/CD deployment pipeline with an integrated unit test.

There are many ways of implementing CI/CD, but for this blog, I will use Jenkins and GiHub to deploy the simple CI/CD pipeline. A Docker container will be used to host the application.  The GitHub repository hosts the application including a Dockerfile for creating an application node. Jenkins is configured with GitHub and Docker Plugin. Read More…
