Self-hosted agents, on the other hand, require you to install and manage the agent software on your own infrastructure, offering greater control over the environment and customization options.

Self-hosted agents are suitable for scenarios requiring specific software installations or access to private resources behind your firewall.

You can group agents together in Agent Pools based on shared characteristics, such as OS or capabilities, for easier job assignment.

Here are the key differences between Microsoft-hosted and self-hosted agents:

To use an agent pool in your pipeline YAML code, simply use the pool keyword and specify the name of the pool you want to use.

Package Formats are a crucial aspect of integrating package management into your CI/CD pipelines. You can publish NuGet packages as artifacts to the built-in Azure Pipelines package management repository.

Publishing packages allows external users to consume them. You can also publish npm, Maven, or Python packages as artifacts to the built-in Azure Pipelines package management repository, or any other package management repository you choose.

For more information about Azure Artifacts, see the relevant documentation.

Pipeline Configuration is a crucial aspect of Azure DevOps CI/CD pipelines. You can define pipelines using YAML code or the classic UI.

To configure a pipeline using YAML, you'll need to create a YAML file called azure-pipelines.yml. This file specifies the structure of your pipeline.

You can also define pipelines using the classic UI, which provides a visual interface for configuring pipeline stages and tasks. This interface is known as the 'classic editor'.

Azure Pipelines provides a wide range of tasks that can be used to customize your pipeline. These tasks include script, download, publish, checkout, and publishBuildArtifacts (legacy).

To work with pipelines as YAML code, you'll need to configure Azure Pipelines to point to your Git repo and define your build process using azure-pipelines.yml. Pushing the YAML code to your version control repository will trigger automatic build and deploy.

Here are some common tasks that can be used in a pipeline:

In addition to YAML and the classic UI, Azure Pipelines also provides a feature called "Azure Pipelines YAML editor". This feature allows you to edit your pipeline YAML file directly in the Azure DevOps interface.

It's worth noting that Microsoft recommends migrating existing classic pipelines to YAML for better maintainability and future-proofing, as well as more granular control and customization compared to the visual editor.

Pipeline management is a breeze with Azure DevOps. You can run an existing pipeline using the 'az pipelines run' command, specifying the pipeline name, branch, and output format.

To update an existing pipeline, simply use the 'az pipelines update' command, providing the pipeline name, new description, and new name. This is a straightforward process that can be completed in a few seconds.

Here's a quick rundown of the commands you can use for pipeline management:

Managing your pipeline is a crucial part of the development process. You can manage your pipeline using Azure CLI.

To run an existing pipeline, use the 'az pipelines run' command. This command allows you to execute your pipeline with a specific name, branch, and output format.

You can update an existing pipeline using the 'az pipelines update' command. This command enables you to modify the name, description, and other details of your pipeline.

To show the details of an existing pipeline, use the 'az pipelines show' command. This command displays the pipeline's name, description, and other relevant information.

Here's a quick rundown of the commands you can use to manage your pipeline:

Environments are a crucial part of pipeline management, allowing you to group resources and configurations specific to different deployment stages or scenarios.

You can reference the environment within the deploy stage, making it easy to manage and deploy your application or infrastructure.

Environments are not just limited to deployment stages like development, testing, staging, and production, but can also be used for other deployment scenarios.

By setting the environment, you can ensure that your application or infrastructure is deployed correctly and efficiently.

Here are some common deployment stages and scenarios where environments are used:

These environments can be referenced in the deploy stage, making pipeline management a breeze.

Azure DevOps CI/CD Pipelines are designed to handle sensitive information securely. Variables are a crucial part of this process, and Azure Pipelines provides a mechanism to store and manage reusable values within your pipelines.

Variables can be categorized into three types: system-defined, user-defined, and secret variables. System-defined variables are automatically set by Azure Pipelines, while user-defined variables are created and defined within your pipeline YAML code or through the Azure Pipelines web interface. Secret variables, on the other hand, are a special type of user-defined variable for storing sensitive information like passwords or API keys.

To further enhance security, Azure Pipelines secrets can include passwords, API keys, access tokens, or any other data that should not be exposed in plain text. Storing secrets separately from your pipeline code prevents them from being accidentally revealed in logs or source code repositories.

Here are the different types of Azure Pipelines variables:

Secrets are a crucial part of pipeline security. Storing sensitive information like passwords or API keys as secrets prevents them from being accidentally revealed in logs or source code repositories.

You can store secrets separately from your pipeline code, which is a good practice. This allows team members to collaborate on pipelines without needing to share sensitive information directly.

Azure Pipelines secrets can include passwords, API keys, access tokens, or any other data that should not be exposed in plain text. This is a common type of secret used in Azure Pipelines.

Azure Key vault is a popular choice for storing secrets with Azure Pipelines. It integrates seamlessly with Azure DevOps, making it a convenient option.

You can also directly create a secret in Azure DevOps under the Library -> Variable Group section by providing a key-value pair. This may be preferable for testing or simple pipelines.

Here are some types of secrets you can store:

Managing secrets in a dedicated location allows for better control and access restriction. Team members can collaborate on pipelines without needing to share sensitive information directly, and secrets can be audited on access and usage for enhanced security posture.

Variables are a crucial part of Azure Pipelines, allowing you to store and manage reusable values within your pipelines.

All variables are stored as strings and can be modified at runtime, making them a flexible way to control configurations, secrets, and other data used throughout pipeline definitions.

You can use variables in expressions to conditionally assign values and further customize your pipeline.

Azure Pipelines variables offer a centralized way to control configurations, secrets, and other data used throughout pipeline definitions.

There are three types of Azure Pipelines variables: system-defined, user-defined, and secret variables. System-defined variables are automatically set by Azure Pipelines, providing information about the pipeline run, such as the build number and source branch.

User-defined variables are variables you create and define within your pipeline YAML code or through the Azure Pipelines web interface. Secret variables are a special type of user-defined variable for storing sensitive information like passwords or API keys, which are encrypted and not exposed in plain text within the pipeline logs.

You can declare variables with names, types (string, bool, etc.), and optional default values in the variables section of your YAML configuration files. These variables can then be referenced throughout your pipeline YAML code using the $(variable_name) syntax.

Here are some key things to keep in mind when working with variables:

Remember to use the correct syntax when referencing variables in your pipeline YAML code: $(variable_name).
