Set up CI with Azure Pipelines

[kaylangan]

I'm a Program Manager on Azure Pipelines. Let me know if you have any questions or suggestions. I'm happy to help!

@kaylangan Thanks for reaching out. Here is my first question: I need to compile with g++-7 on Linux. A program named g++-7 doesn't seem to be installed in the VM. How can I configure my build to use this compiler?

I think you can add a script and install using apt-get. That said, I'm not sure how long that'll take--if it seems to be taking too long, let me know.

@kaylangan Thanks! Similar question for Windows: I'm running the VM vs2017-win2016, which uses VisualStudio 2017. Is there a possibility to compile with VisualStudio 2015?

[kaylangan]

Would the vs2015-win2012r2 image work, or do you require VS2015 with Windows Server 2016? https://docs.microsoft.com/en-us/azure/devops/pipelines/agents/hosted?view=vsts&tabs=yaml#use-a-microsoft-hosted-agent

@kaylangan That's what I was looking for. I was just unable to find the VM's name vs2015-win2012r2 in the documentation. Could you give me a pointer, where such things are described (or improve the docu if there isn't any :wink:)?

[kaylangan]

No problem! The doc I linked to above describes the VMs we offer and has a "cheat sheet" of sorts:

@kaylangan Ah, I didn't realize that the center column of the table refers to the VM names. Now I have another problem: conda is not installed on the vs2015-win2012r2 VM. How can I get it?

[ukoethe]

@kaylangan: Update: I tried various approaches to install conda in user space, but nothing worked so far. Without conda, the vs2015-win2012r2 VM is somewhat pointless for me. As an aside, I found that only Python 2.7 is installed (at C:\Python27), contrary to what is reported in the vs2015-on-windows-2012r2 documentation.

@ukoethe can you try installing miniconda via chocolatey?

[ukoethe]

I don't see chocolatey listed on https://github.com/adventworks/hosted-pool-images/blob/2017.10.02/vs2015-on-windows-2012r2/image.md. Is it installed?

@kaylangan update: choco is not in the PATH, so no progress 🤔.

[ukoethe]

@kaylangan The key question may be this: Is there any possibility to debug a failing build interactively in the CI virtual machine, or in a VM with identical setup (somewhere in the cloud or by means of a local copy)? Restarting every build from scratch in a trial-and-error fashion is just really time-consuming.

[kaylangan]

You'll need to install choco as admin. Unfortunately, we don't have a way to log into the machines and interactively debug.

[ukoethe]

@kaylangan update: I just noticed that VS2015 (and older VS versions) are also installed in the vs2017-win2016 VM (although the VM's name suggests otherwise), so there is actually no need to use vs2015-win2012r2. I'll go ahead this way.

[ukoethe]

superseded by PR #448

@kaylangan good news: all builds work now.

Unfortunately, we don't have a way to log into the machines and interactively debug.

If you'd get this to work, it will be the killer feature of azure-pipelines.
