自托管 azure 代理 - 如何配置管道以共享相同的构建文件夹

Question

We have a self-hosted build agent on an on-prem server.

We typically have a large codebase, and in the past followed this mechanism with TFS2013 build agents:

• Daily check-ins were built to c:\work\tfs\ (taking about 5 minutes)
• Each night a batch file would run that did the same build to those folders, using the same sources (they were already 'latest' from the CI build), and build the installers. Copy files to a network location, and send an email to the team detailing the build success/failures. (Taking about 40 minutes)

The key thing there is that for the nightly build there would be no need to get the latest sources, and the disk space required wouldn't grow much. Just by the installer sizes.

To replicate this with Azure Devops, I created two pipelines. One pipeline that did the CI using MSBuild tasks in the classic editor- works great Another pipeline in the classic editor that runs our existing powershell script, scheduled at 9pm - works great

However, even though my agent doesn't support parallel builds what's happening is that: The CI pipeline's folder is c:\work\1\ The Nightly build folder is c:\work\2\

This doubles the amount of disk space we need (10gb to 20gb) They are the same code files, just built differently.

I have struggled to find a way to say to the agent "please use the same sources folder for all pipelines"

What setting is this, as we have to pay our service provider for extra GB storage otherwise.

Or do I need to change my classic pipelines into Yaml and somehow conditionally branch the build so it knows it's being scheduled and do something different? Or maybe, stop using a Pipeline for the scheduled build, and use task scheduler in Windows as before?

(I did try looking for the same question - I'm sure I can't be the only one).

Answer 1

There is "workingDirectory" directive available for running scripts in pipeline. This link has details of this - https://docs.microsoft.com/en-us/azure/devops/pipelines/tasks/utility/command-line?view=azure-devops&tabs=yaml

Answer 2

The number '1' '2'...'6' of work folder c:\work\1\ , c:\work\2\ ... c:\work\6\ in your build agent which stands for a particular pipeline.

Agent.BuildDirectory

The local path on the agent where all folders for a given build pipeline are created. This variable has the same value as Pipeline.Workspace. For example: /home/vsts/work/1

If you have two pipelines, there will also be two corresponding work folders. It's an except behavior. We could not configure pipelines to share the same build folde. This is by designed.

If you need to use less disk space to save cost, afraid stop using a Pipeline for the scheduled build, and use task scheduler in Windows as before is a better way.
