Training Machine Learning (ML) Model with Azure Pipeline and Output ML Model as Deployable Artifact

Training a machine learning model requires wide range of quality data to get the ML model trained in such a way that it can provide accurate predictions. Azure build pipeline can run the python tests written to validate the data quality and the train a model with uploaded data to Azure ML workspace. In this post on “Setup MLOPS workspace using Azure DevOps pipeline” it is clearly explained how to setup an Azure ML workspace in a new resource group dynamically with Azure CLI ML command extension. The post “Setup MLOPS workspace using Azure DevOps pipeline” as well as this post on training a model with Azure pipelines use the open source ML repo (https://github.com/SaschaDittmann/MLOps-Lab.git) with data by Sascha Dittmann, and code to train a model.

Replacing iOS .plist Array Properties in Azure Release Pipelines

.plist files are used by iOS applications to keep configuration properties. These files support arrays as configurations. In deployment process of Azure DevOps pipelines you may want to update these plist files to have values relevant to the target deployment environments. Let’s see usage of plistbuddy utility to update array items in plist files as the plutil (http://scriptingosx.com/2016/11/editing-property-lists/) is unable to apply the changes.

Building Code from Multiple Repos with YAML Pipelines

You could only build code from a single repo using classic build pipelines in Azure DevOps. Now with multiple repo support added to YAML build pipelines (pipeline as code), you can decide which of the repos you want to checkout and build, in a single pipeline build sequence. Let’s see the steps in detail.

Implementing Simple and Effective Branching and Deployment Strategy with Azure DevOps

In the previous post, we have discussed, a simple and effective branching and deployment strategy as a concept. Let’s now have a look at key implementation considerations of the proposed strategy with Azure Git repos and Azure Pipelines.
Let’s have a look at pictorial representation of the proposed strategy first.
