⁠Docker Image for Microsoft OpenPAI

⁠How to maintain docker image by using dockerfile

When submitting jobs to Microsoft OpenPAI⁠, a docker image in dockerhub⁠ is required in the job config. This tutorial aims to demonstrate how to maintain a docker image for OpenPAI by using dockerfile.

⁠Prerequisites

• An account in dockerhub. You can register a free account in dockerhub to push, update and share your own docker image. the account is nessesary if you want to build your own docker image in OpenPAI.

• An account in github. You will use github account to create a new repo for dockerfile.

⁠Write your own dockerfile

• Write your own dockerfile to build docker image. Here is the official dockerfile reference⁠, you might use on of the OpenPAI images⁠ as base image.

⁠Push dockerfile to a new github repo

• Create a new github repo to maintain the dockerfile and others files needed during docker image build process.

• Use this repo to maintain dockerfile as a source control.

⁠Create an autobuild image repo in dockerhub

• Use your dockerhub account to create an autobuild image repo for your docker image and link the github repo created in the previous step. Here is an official guide⁠ for how to create a autobuild image. Below images illustrate an example process. You need to link your github account to this dockerhub account first.

• In the butobuild settings, you can triger a docker image build process manually, or auto build everytime when the github repo updates.

• You can check the build details whether the docker image build process succeeds or fails.

• After setting the auto build repo, you can focus on the dockerfile in github. And the docker image will built automatically based on the dockerfile.

⁠Use this autobuild image as OpenPAI job docker image

• Use this autobuild image as OpenPAI job docker image. And this docker image will updated whenever the dockerfile changed.
