Azure Devops - How to use classic pipeline variable group in YAML pipeline

Hi All!

When we need to use a group of variables in a pipeline, we can go for variable group instead of variables. The main usage of variable group is that can be used it across multiple pipelines in the same project.

For example, I have a below variable group in my azure Devops.

By default variable groups can be used across classic pipelines without any explicit permission granted but that variable group could not be used by YAML pipelines typically.

So, How how can I use that variable group in my YAML pipeline?

We can achieve it through "Pipeline permissions" option on top of variable group page. In the below image, I grant permission to my dotnet6app YAML pipeline to use variable group

We can revoke if we don't need a YAML pipeline should not access variable group as below.

Now, I want my all pipelines should use variable group. I don't want manual intervention for my future creation pipelines as well. so, we can grant "open access" - which grants permission to all YAML pipelines of the project.

Azure Public IP(s) are zone redundant free of cost natively - Generally Available Availability zone gives high availability to an application as well as information by forestalling the physical datacenter disappointments by involving replication of the asset in extra datacenter. Azure typically has 3 zones per region (and not all regions support zone). Thus, while setting up the environment we really want to pick the right region based on our usecase. Public IP helps to access a resource or an application publicly. Azure offers 2 types of SKU for public IP as below Basic Standard Only Standard SKU gives zone facility. Basic SKU is always non-zonal and this SKU also will be retired 09/2025. Standard public IP can be fell into any of the below category No Zone / Non-Zonal - No availability zone at all Zonal - Our services can be replicated in any one of selected zones from three zones. Zone redundant - Resource will be replicated in all 3 zones. It is opposite of...
create and read a file in Linux As a cloud and Devops engineers, we need to know to work with Linux is always helpful to handle some critical situations. There are multiple ways to create and read a file in Linux. In this article we're going to learn about touch command. Let's work with followings in this article pwd - To show present working directory touch - To create an empty file ls - To list the files from the current directory echo - To display message as well as write into a file. '>' - write into a file. '>>' - append it to a file cat - To read content of file we'll see writing and appending into a file in my upcoming post.
Avoid YAML Validation error in azure devops pipeline Hi All! Consider a scenario that you committed a YML CI/CD file on the repository with some syntax, indentation and/or other error(s). so that pipeline failed. After you find some errors and rectified in the repository file and committed again but pipeline still gets failed because some errors are still there. Now you afraid that even if you fixed error in all the places, what happens if pipeline failed again because your project lead or manager set up build notification mail trigger for build success and fails. you need to answer them for build fail reason. Azure devops pipelines offers YAML validation feature after altered and before committed and before run pipeline. To utilize this feature, what we do is, Instead of modifying the file from repository, Do as below Go to the specific build click "Edit Pipeline" Modify/fix errors and click "validate" as shown in the picture below ...
