Is it possible to default to self-hosted runners? - github

I am planning to move from GitLab to GitHub and just started to experiment with GH Actions.
One thing I see is that I have to indicate that I want to run on a self-hosted runner for each job.
Is there a way to set a default for the Organization, or have it defined only once in the workflow YAML file?

I don't believe so. This is just another attribute that you need to consider when specifying a place for a job to run. For example, you already need to specify what type of system (e.g., OS and version) you want to use for each job via the runs-on directive, since there's no reasonable way to guess, so specifying self-hosted instead isn't exceptionally burdensome.

Remove default labels on GitHub self hosted runner

When creating a new self-hosted runner for GitHub (enterprise), some default labels (Windows, X64, self-hosted) are automatically added. I can also add custom labels with the --labels parameter.
The thing is that I would like to reserve this runner for some specific workflows, but without restricting the repositories where it can be called. Because some projects use this default labels to choose runner, I would like to remove them.
I tried to find where this labels are created, but I'm fearing they are created server-side and that I would not have control over them...
Did anybody deal with a similar situation?
Thank you.
You cannot remove the default labels. If this runner is meant to be used exclusively by specific repos, then move them into a Runner Group and only allow that groups to be used by those repos.
No other way to configure that at the moment.

During a release, how to get a list of server names deployed to from a deployment group in a task to use in another job?

What is the way to get a list of server names that were deployed to so they can be used in another job with a different agent in the same deployment pipeline?
We have a number of servers in a deployment group that get deployed to. We would like to point an automated test server to each of these environments to confirm the deployment went correctly. Therefor we need a list of the servers that were deployed.
Since the list of servers could grow or shrink we can't hard code all the servers to a variable.
As a workaround we created a Powershell step to call the REST API to get the deployment group machine details. However, we would like to achieve this using variables / outputs etc in the Azure Devops interface.
One thing to be aware of is that variables you might set by command do not persist between phases. If you want to know the deployment servers that were deployed during a phase, you will need to find those during the test agent phase you are executing.
I think you answered your own question though. I believe most of the answers you get will be to use the API to get the information that you are desiring. That being said, the only real sure-fire was I think would be for you to add a step to the deployment group phase and let it run the tests on the deployment server.
Not the cleanest solution, but you could also have the deployment group trigger a build definition passing the server name. The build task would just have the testing portion that you want to run. You could have that release step depend on the completion/status of the build definition.
Some features to keep in mind when implementing whatever you decide:
Automatically deploy to new targets in a deployment group
Deploy to failed targets in a Deployment Group
From what I can see, there is no easy way to get at what you want. As per designer documentation:
"When you specify multiple jobs in a build pipeline, they run in parallel by default. You can specify the order in which jobs must execute by configuring dependencies between jobs. Job dependencies are not yet supported in release pipelines. Multiple jobs in a release pipeline run in sequence."
I would imagine this is due to the added complexity inherent in allowing jobs to be run on x number of machines.
The yaml documentation doesn't seem to make the same distinction, but I think it is still a not yet feature, as yaml release pipelines as a whole seem to be a roadmap item.

Reusing PowerShell Scripts in Azure DevOps

I have a PowerShell script that I want to re-use across multiple build pipelines. My question is, is there a way I can "store" or "save" my PowerShell script at the project or organization scope so that I can use it in my other build pipelines? If so, how? I can't seem to find a way to do this. It would be super handy though.
It is now possible to check out multiple repositories in one YAML pipeline. You could place your script in one repository and check it out in a pipeline of any other repository. You could then reference the script directly on the pipeline workspace.
More info here.
Depending on how big theese scripts are you can create Taskgroups that contain powershell-tasks with the script as inline-powershell. But this only works on project-scope..
Another attempt i'd try would be to create a repo containing your powershell-scripts, add this repo as submodule in the repository you are trying to build and then call the scripts from the submodule-folder. But this only works when using git-repos.
Or you could create a custom build-task that contains your script.
From what I have seen, no.
A few different options I have explored are:
If using a non-hosted agent, saving the file onto the build server. Admittedly this doesn't scale well, but it is better than copy/pasting the script all over. I was able to put these scripts into version control and deploy them via their own pipeline so that might be an solution for scaling (if necessary)
Cloning another repository that has these shared scripts during the process.
I've been asking for this feature for a bit, but it seems the Azure DevOps team has higher priorities.
How about putting the powershell in a nuget package and install that in depending projects?
I just discovered YAML templates (https://learn.microsoft.com/en-us/azure/devops/pipelines/process/templates?view=azdevops#step-re-use).
I think it may help you in this case (depending how large it is your file), you can put an inline powershell script in that template yaml, and reuse it on your main yaml.
Documentation is pretty straightforward.

Updating the a text file during a vsts release

We have a requirement to update a text file during the release phase in VSTS depending on which environment the solution is being deployed too. I am a complete beginner to this.
I've looked at variables but I'm not clear on whether this will solve this particular problem.
There are many tasks that can update the file during the release, such as RegexReplace Build task (As rickjerrity mentioned), Replace Tokens etc…, you also can do it programming (e.g. PowerShell) during release.
Steps:
Add the environments with same name for each environment (Set Scope)
Using that variable in task.

TFS Release Management 2015 - How to restrict environment deployment order

Quick question.
Is there a way to constrain/restrict what order users can can deploy builds to environments?
For example if I have these four environments configured with manual push-button deploy (not-automated) I can start all four together if I want. I don't have to wait for the other to be done before kicking off the next one:
DEV
TEST
STAGE
PROD
Microsoft seems to be missing this feature in TFS 2015. It would make sense to offer a deployment condition that states that previous environments must have successful deployments before you can run push-button deploy for the next.
Yes, I know, you are going to say "but you can automate that so the deploys run in the order you want." Management here does NOT want that. They want push button deployment for each environment WITH a constraint that previous environments must be completed first.
This means a manual start for each environment.
Other than having the release manager "eyeball" the situation before pushing the button for the next environment I can't see a way to configure this rule.
Any ideas?
There is not any restriction on manually deploy situation for now. This is designed for giving you the ability to override the release process.
Note that you can always deploy a release directly to any of the
environments in your release definition by selecting the Deploy
action when you create a new release.
In this case, the environment triggers you configure, such as a
trigger on successful deployment to another environment, do not apply.
The deployment occurs irrespective of these settings. This gives you the ability to override the release process. Performing such
direct deployments requires the Manage deployments permission, which
should only be given to selected and approved users.
Source Link: Environment triggers
Suggest you use automation triggers, you could use Parallel forked and joined deployments, in combination with the ability to define pre- and post-deployment approvals, this enables the configuration of complex and fully managed deployment pipelines to suit almost any release scenario.
If you insist on manual push-button deploy, you may have to ask the release manager "eyeball" the situation to restrict environment deployment order as you mentioned.
