In-Depth Guide to Building a PowerShell Pipeline in Azure DevOps

From the left navigation, click API permissions. This article focused specifically on Best Practices when using Azure Pipelines. Stay tuned for another article on generic best practices, where I explain how to use git workflows and manage infrastructure across environments. Use the same reasoning above to determine if in your use case, you need access and when to restrict it. Continue reading to learn how the Key Vault integration works.

We will also use this strategy to authenticate to Azure to manage our infrastructure. You can also give the file a .hcl extension for your editor to do syntax highlighting. I use .conf as a convention to signal a warning that this file may contain sensitive information and should be protected. On my local machine, I initialize Terraform by passing whole configuration file.

Multi-Line Code

This is what the pipeline task reads to indicate success or failure. By default, the pipeline sets all PowerShell scripts to an $ErrorActionPreference value to Stop. This means that all soft and hard-terminating errors will force PowerShell to return a non-zero exit code thus failing the pipeline task. Once the scripts are downloaded to the pipeline agent, you can then reference them in a task via the [System.DefaultWorkingDirectory predefined variable. If you’re not using an inline code task to run a script, you’ll have to save a script somewhere.

This is not something our InfoSec teams would be very happy about. Notice the Override template parameters field has the database user name as a string but the password value is passed as a variable. Select the Service connection you created in previous step for Azure subsciption in Azure Key Vault task. Select the Select principal and search for the security principal that you created earlier and select it. Enter the following command to get Azure SubscriptionID and copy the subscription ID and name to notepad.

See Source Repo on GitHub for other advantages. The Azure DevOps service has its roots in Visual Studio Team Foundation Server and as such it carries legacy features, including Classic Pipelines. If you’re creating new pipelines, do not start with classic pipelines. If you have classic pipelines, plan on migrating them to YAML. Industry best practice is to author Pipelines as Code and in Azure Pipelines, that means YAML Pipelines. If you’d run this task without using the ignoreLastExitCode attribute, you’d find the task still shows success.

For now, we will provide read-only permissions to secrets only. Now, using + Select Members select the service principal that has been craeted and click on Next. We will configure permissions to let a service principal to read the value. We will create a key vault, from the Azure portal, to store a MySQL server password.

Using Codefresh Workflows to Automate CI/CD Pipelines

The task is in essence a wrapper of the VSTest task and the configuration is the same. The only additional configuration is related to whether the build agent is hosted at the cloud or at on-premisses server. To successfully deploy to Connect this pipeline will need several environment variables.

  • Many popular code hosting providers and independent software companies offer CI and CD services.
  • Can be standard terraform vars file or .env file.
  • If I use a Service Connection, I have increased my attack surface to 3 locations.
  • No matter how simple or complex an application is, choosing the right configuration provider right at the start will mak…
  • For example, signIdIdentity becomes signing_identity.

Depending on the options chosen, the pipeline agent will either be on Windows or Linux. This article isn’t going to cover building custom AzDo extensions, but you should know this is possible. You can move the “interface” up to the pipeline level instead of down at the script level, allowing you to reuse existing scripts easily. Not only can you define and read variable values in the YAML pipeline, you can also do so within scripts. Just like you have variables in a script, you also have variables in a pipeline. Variables are defined a few different ways and their value can be accessed differently depending on the context.

Because the task doesn’t care what exit code PowerShell actually returns. It uses the value of $LASTEXITCODE to determine that. You can then see the values were passed to the script in the job output log. You can provide values to the $foo and $bar parameters via the arguments attribute in the YAML pipeline like below.
