The demands keyword is supported by private pools. You can check for the existence of a capability or a specific string. Learn more about demands. The environment keyword specifies the environment or its resource that is targeted by a deployment job of the pipeline. An environment also holds information about the deployment strategy for running the steps defined inside the job. If you specify an environment or one of its resources but don't need to specify other properties, you can shorten the syntax to:.
You can reduce the deployment target's scope to a particular resource within the environment as shown here:. The server value specifies a server job. Only server tasks like invoking an Azure function app can be run in a server job.
The script keyword is a shortcut for the command-line task. The task runs a script using cmd. Learn more about conditions , timeouts , step targets , and task control options for all tasks.
The bash keyword is a shortcut for the shell script task. The pwsh keyword is a shortcut for the PowerShell task when that task's pwsh value is set to true. Each PowerShell session lasts only for the duration of the job in which it runs. Tasks that depend on what has been bootstrapped must be in the same job as the bootstrap.
The powershell keyword is a shortcut for the PowerShell task. The task runs a script in Windows PowerShell. PowerShell provides multiple output streams that can be used to log different types of messages. The Error, Warning, Information, Verbose, and Debug streams all convey information that is useful in an automated environment, such as an agent job.
PowerShell allows users to assign an action to each stream whenever a message is written to it. For example, if the Error stream were assigned the Stop action, PowerShell would halt execution anytime the Write-Error cmdlet was called.
The PowerShell task allows you to override the default PowerShell action for each of these output streams when your script is run. This is done by prepending a line to the top of your script that sets the stream's corresponding preference variable to the action of choice. The following table lists the actions supported by the PowerShell task and what happens when a message is written to the stream:.
The following table lists the output streams supported by the PowerShell task and their default actions:. The last exit code returned from your script is checked by default. A nonzero code indicates a step failure, in which case the system appends your script with:. The publish keyword is a shortcut for the Publish Pipeline Artifact task. The task publishes uploads a file or folder as a pipeline artifact that other jobs and pipelines can consume.
Learn more about publishing artifacts. The download keyword is a shortcut for the Download Pipeline Artifact task. The task downloads artifacts associated with the current run or from another Azure pipeline that is associated as a pipeline resource.
All available artifacts from the current pipeline and from the associated pipeline resources are automatically downloaded in deployment jobs and made available for your deployment. To prevent downloads, specify download: none. Learn more about downloading artifacts. Nondeployment jobs automatically check out source code.
Use the checkout keyword to configure or suppress this behavior. In addition to the cleaning option available using checkout , you can also configure cleaning in a workspace. If you're running the agent in the Local Service account and want to modify the current repository by using git operations or loading git submodules, give the proper permissions to the Project Collection Build Service Accounts user.
For more information, see Check out multiple repositories in your pipeline. Tasks are the building blocks of a pipeline. There's a catalog of tasks available to choose from. Learn more about conditions , timeouts , and task control options for all tasks.
Syntax highlighting is available for the pipeline schema via a Visual Studio Code extension. The extension includes a JSON schema for validation. Skip to main content.

Stage B Schema Example name: string build numbering format resources: pipelines: [ pipelineResource ] containers: [ containerResource ] repositories: [ repositoryResource ] variables: several syntaxes, see specific section trigger: trigger pr: pr stages: [ stage templateReference ] If you have a single stage , you can omit the stages keyword and directly specify the jobs keyword Stage A stage is a collection of related jobs.
Schema Example stages: - stage: string name of the stage A-Z, a-z, , and underscore displayName: string friendly name to display in the UI dependsOn: string [ string ] condition: string variables: several syntaxes, see specific section jobs: [ job templateReference] This example runs three stages, one after another.
The middle stage runs two jobs in parallel. This example runs two stages in parallel. For brevity, the jobs and steps are omitted. Note If you have only one stage and one job, you can use single-job syntax as a shorter way to describe the steps to run.
If maxParallel is unspecified or set to 0, no limit is applied. If maxParallel is unspecified, no limit is applied. As an example, let's have a look at how you can use JavaScript to generate a Kubernetes Pod definition. You can execute the script with the node binary:. What if you want to change the environment variable?
The code above uses a function and an argument to customise the environment variables. You could save the above output in a file named pod. You could also skip kubectl altogether and submit the JSON to your cluster directly.
Using the official Javascript library, you could have the following code:. Writing resource definition for objects such as Deployments, Services, StatefulSets, etc. You can find the above example translated in Java, Go, Python, C in this repository. Helm is a package manager, release manager and a templating engine.
The template cannot live in isolation and should be placed in a directory that has a specific structure — a Helm chart. The values. Please note that, unless a parameter is listed in the values.
In the example above, you can't customise the name of the container or the name of the Pod. Helm uses the Go templating engine which only replaces values. Helm is usually a popular choice because you can share and discover charts — a collection of Kubernetes resources.
The bottom line is that all of the above tools require you to learn one more language or DSL to handle configuration. If you have to introduce a new language, why not using a real language that perhaps you already use? When you manage multiple environments and multiple teams, it's natural to look for strategies to parameterise your deployments.
And templating your Kubernetes definitions, it's the next logical choice to avoid repeating yourself and standardise your practices. There're several options to template YAML some of them treat it as a string. You should avoid tools that don't understand YAML because they require extra care on things such as indentation, escaping, etc. Instead, you should look for tools that can mangle YAML such as yq or kustomize. Be the first to be notified when a new article or Kubernetes experiment is published.
This way you would have to run through all 20 repos to add that task - not the smartest way of working.. Well with the setup as we have it now, you could add the other environment s in Azure DevOps and then add a new deploy stage to the deploy file:.
Instead of doing that, we can use YAML templates to split parts of our build or deploy files into their own "template" YAML file - we can even store these YAML files in a separate repository and then just pull them in to use them. So on a separate repo you can add your files. I will fx add a build template file:. With this change, we can now call the template in our build. Notify me of new comments via email.

Change the Pipeline to Use the Template Now you want to change the pipeline definition to use the template yaml file that you have created. Share this: Twitter Facebook.
