Kaldi Docker Image Builder

This repository contains the codes needed for automating Kaldi's Docker image builds. It uses Terraform to provision the required resources in the cloud to build and push the images to the container registary. Terraform is a provider agnostic tool and most of the major public and private cloud providers are supported. In this repository the examples are based on Microsoft Azure, but any other supported cloud provider can be used.

To build this sample, first rename build-env.tfvars.empty to build-env.tfvars and update the corresponding values. For Azure, please follow these instructions.

Building Docker images

To build the latest CPU-based image, run:

make cpu

It will provision a VM, install the required software to build Kaldi's CPU-based Docker image, then build and push them to the container registery defined in build-env.tfvars and then clean up the resources.

The default tag for the Docker images is latest, it can be changed by passing a tag parameter:

make tag=SOMETAG cpu

Similarly to build GPU-based images, run:

make gpu

To change the region, VM type and other settings or to use a different cloud provider, check build-env.tf files. The important part for building and pushing the images is located in provisioner "remote-exec" section of the files.
