Inputs

workingDirectory - Working Directory
Input alias: cwd. string.

Current working directory where the script is run. Empty is the root of the repo (build) or artifacts (release), which is $(System.DefaultWorkingDirectory).


appSourcePath - Application source path
string.

Absolute path on the runner of the source application code to be built. If not provided, the 'imageToDeploy' argument must be provided to ensure the Container App has an image to reference.

When pushing a new image to ACR, the acrName and appSourcePath task inputs are required.


azureSubscription - Azure Resource Manager connection
Input alias: connectedServiceNameARM. string. Required.

Specify an Azure Resource Manager service connection for the deployment. This service connection must be linked to the user's Azure Subscription where the Container App will be created/updated. This service connection must have proper permissions to make these changes within the subscription, for example Contributor role.


acrName - Azure Container Registry name
string.

The name of the Azure Container Registry that the runnable application image will be pushed to.

When pushing a new image to ACR, the acrName and appSourcePath task inputs are required.


acrUsername - Azure Container Registry username
string.

The username used to authenticate push requests to the provided Azure Contrainer Registry. If not provided, an access token will be generated via 'az acr login' and provided to 'docker login' to authenticate the requests.


acrPassword - Azure Container Registry password
string.

The password used to authenticate push requests to the provided Azure Contrainer Registry. If not provided, an access token will be generated via 'az acr login' and provided to 'docker login' to authenticate the requests.


dockerfilePath - Dockerfile path
string.

Relative path (_without file prefixes (see the following Examples) to the Dockerfile in the provided application source that should be used to build the image that is then pushed to ACR and deployed to the Container App. If not provided, this task will check if there is a file named 'Dockerfile' at the root of the provided application source and use that to build the image. Otherwise, the Oryx++ Builder will be used to create the image.


imageToBuild - Docker image to build
string.

The custom name of the image that is to be built, pushed to ACR and deployed to the Container App by this task. Note: this image name should include the ACR server; e.g., <acr-name>.azurecr.io/<repo>:<tag>. If this argument is not provided, a default image name will be constructed in the form of <acr-name>.azurecr.io/ado-task/container-app:<build-id>.<build-number>.


imageToDeploy - Docker image to deploy
string.

The name of the image that has already been pushed to ACR and will be deployed to the Container App by this task. Note: the image name should include the ACR server; e.g., <acr-name>.azurecr.io/<repo>:<tag>. If this argument is not provided, the value provided (or determined) for the 'imageToBuild' argument will be used. If this image is found in an ACR instance that requires authentication to pull, the acrName argument, or the acrUsername and acrPassword arguments, can be provided to authenticate requests to the ACR instance.


containerAppName - Azure Container App name
string.

The name of the Azure Container App that will be created or updated. If not provided, this value will be in the form of ado-task-app-<build-id>-<build-number>.


resourceGroup - Azure resource group name
string.

The existing resource group that the Azure Container App will be created in (or currently exists in). If not provided, this value will be in the form of <container-app-name>-rg.


containerAppEnvironment - Azure Container App environment
string.

The name of the Azure Container App environment to use with the application. If not provided, an existing environment in the resource group of the Container App will be used, otherwise, an environment will be created in the format of <container-app-name>-env.


runtimeStack - Application runtime stack
string.

The platform version stack used in the final runnable application image that is deployed to the Container App. The value should be provided in the formation <platform>:<version>. If not provided, this value is determined by Oryx based on the contents of the provided application. Please refer to this document for more information on supported runtime stacks for Oryx.


targetPort - Application target port
string.

The target port that the Container App will listen on. If not provided, this value will be "80" for Python applications and "8080" for all other supported platforms.


location - Location of the Container App
string.

The location that the Container App (and other created resources) will be deployed to.


environmentVariables - Environment variables
string.

A list of environment variable(s) for the container. Space-separated values in 'key=value' format. Empty string to clear existing values. Prefix value with 'secretref:' to reference a secret.


ingress - Ingress setting
string.

Possible options: external, internal, disabled. If set to external (default value if not provided when creating a Container App), the Container App will be visible from the internet or a VNET, depending on the app environment endpoint configured. If set to internal, the Container App will be visible from within the app environment only. If set to disabled, ingress will be disabled for this Container App and will not have an HTTP or TCP endpoint.


yamlConfigPath - YAML configuration file path
string.

Full path (on the executing Azure Pipelines agent) to the YAML file detailing the configuration of the Container App.

The resourceGroup property in the YAML configuration file will not be used; the value for this either comes from the resourceGroup argument provided to the task, or the default resource group name generated by the task. All other properties provided in the YAML configuration file will override the values provided as arguments to this task; for example, if the containerAppName argument is provided to the task, and the name property is set in the YAML configuration file, the name property in the YAML file will be used when creating or updating the Container App.

Image and application source arguments (e.g., appSourcePath, imageToDeploy) will still be used to first build and/or push an image that is used by the Container App; in this case, the provided YAML configuration file will need to reference the image specified by imageToDeploy (or imageToBuild, depending on your scenario).

When creating a new Container App, all properties listed in the YAML configuration file (except resourceGroup as mentioned above) will be set when the Container App is created. When updating an existing Container App, only the properties listed in the file will be updated on the Container App.

Currently, the YAML file does not support setting up managed identity authentication for the container registry used; for more information on this issue, please see this GitHub issue.

In cases where the yamlConfigPath argument is provided, the YAML file will be passed through to the corresponding az containerapp command, either create or update depending on your scenario. For more information on the intended behavior when the YAML configuration file is provided, please see the documents linked for the corresponding commands.

For more information on the structure of the YAML configuration file, please visit this site.


disableTelemetry - Disable telemetry
boolean.

If set to 'true', no telemetry will be collected by this Azure DevOps Task. If set to 'false', or if this argument is not provided, telemetry will be sent to Microsoft about the Container App build and deploy scenario targeted by this Azure DevOps Task.


Task control options

All tasks have control options in addition to their task inputs. For more information, see Control options and common task properties.

Output variables

None.

Remarks

This Azure Pipelines Task allows users to easily deploy their application source to an Azure Container App in their Azure Pipelines workflow by either providing a previously built image, a Dockerfile that an image can be built from, or using a builder to create a runnable application image for the user.

The task has the following two usage patterns.

  • Pushing an image to ACR - when pushing a new image to ACR, the acrName and appSourcePath task inputs are required.
  • Deploying a previously pushed image - when deploying a previously pushed image, the imageToDeploy task input is required. If this image is found in an ACR instance that requires authentication to pull, the acrName argument, or the acrUsername and acrPassword arguments, can be provided to authenticate requests to the ACR instance.

Note

Although no task input is officially marked as "required" in the metadata of this task, some inputs will need to be provided in order for this task to successfully run using one of the two main usage patterns.

If no Dockerfile is found or provided in the provided application source, the following steps are performed by this task:

  • Uses the Oryx++ Builder to build the application source using Oryx to produce a runnable application image
  • Pushes this runnable application image to the provided Azure Container Registry
  • Creates or updates a Container App based on this image

If a Dockerfile is found or discovered in the application source, the builder won't be used and the image will be built with a call to docker build and the Container App will be created or updated based on this image.

If a previously built image has already been pushed to the ACR instance and is provided to this task, no application source is required and the image will be used when creating or updating the Container App.

Running this task on Microsoft-hosted agents

If you are running this task on a Microsoft-hosted agent, you may find that this task is not able to run successfully with the following operating systems:

  • macOS
    • The macOS runners provided by Microsoft do not come installed with Docker (more information here); as a result, this task is not able to run any docker commands, such as pushing the built runnable application images to ACR.
  • Windows
    • The Windows runners provided by Microsoft comes with Docker installed, but by default, Linux-based images are unable to be pulled down; as a result, this task is not able to pull down the Oryx builder to create runnable application images from provided application source.

Please see the below Docker prerequisite section for more information.

Data/Telemetry Collection Notice

By default, this Azure DevOps Task collects the following pieces of data for Microsoft:

  • The Container App build and deploy scenario targeted by the user
    • i.e., used the Oryx++ Builder, used a provided/found Dockerfile, or provided a previously built image
    • Note: the image name is not collected
  • The processing time of the task, in milliseconds
  • The result of the task
    • i.e., succeeded or failed
  • If the Oryx++ Builder is used, events and metrics relating to building the provided application using Oryx

If you want to disable data collection, please set the disableTelemetry argument to true.

Prerequisites

Prior to running this task, Azure resources and an Azure DevOps service connection are either required or optional depending on the arguments provided to this task.

Azure DevOps Service Connection

To deploy to Azure, an Azure subscription has to be linked to Team Foundation Server or to Azure Pipelines using the Services tab in the settings section. Add the Azure subscription to use in the Build or Release Management definition by opening the Account Administration screen (gear icon on the top-right of the screen) and then click on the Services Tab.

Create the ARM service endpoint and use the 'Azure Resource Manager' endpoint type; for more information on creating service connections, please follow this document.

Azure CLI

This task requires that the Azure CLI is installed on the Azure Pipelines agent to execute a variety of commands throughout the execution of the task. For more information on how to install the Azure CLI on the agent, please see this document. If an agent is already running on the machine on which the Azure CLI is installed, ensure that you restart the agent so that all relevant environment variables are updated.

Docker

This task requires that Docker is installed on the Azure Pipelines agent to push images to the provided Azure Container Registry. For more information on how to install Docker on the agent, please see this document.

In addition, users running this task with a Windows agent may encounter an issue with not being able to pull down Linux-based images; to resolve this, please visit this site or located the DockerCli.exe file on your agent (typically in the Program Files\Docker\Docker folder) and run

& `.\DockerCli.exe` -SwitchDaemon

If Docker is not installed on the agent running this task, the following scenario(s) are still enabled:

  • Providing a previously built image to the imageToDeploy argument that the Container App deploys with

If Docker is on the agent, but unable to work with Linux-based images, the following scenario(s) are still enabled:

  • Providing a previously built image to the imageToDeploy argument that the Container App deploys with
  • Providing a Dockerfile as a part of your application source that will be built and deployed with the Container App
    • Note: the Dockerfile cannot have any Linux-based image layers

pack CLI

The pack CLI is maintained by the Cloud Native Buildpacks project and is used by this task to create runnable application images for the user when the application source code is provided and no additional Dockerfile is provided or found. A builder was created by Oryx to take in the application source code provided to this task and produce an image that could then be pushed to an image registry and used within a Container App to build and run the application.

A stable version of the pack CLI is installed on the Azure Pipelines agent executing the task, and depending on the base OS of this agent, different tools will be leverage to assist with the installation:

  • On Windows runners:
    • A set of PowerShell commands are executed to do the following:
      • Creates a pack folder in the agent's temporary folder, if the pack folder doesn't already exist
      • Downloads the pack CLI .zip into this pack folder
      • Unzips the content from this .zip and places them in the pack folder
      • Deletes the .zip
  • On non-Windows runners:
    • curl will be used to pull down the .tgz containing the pack executable
    • tar will be used to unzip the .tgz and place the pack executable in /usr/local/bin

Azure Container Registry

An Azure Container Registry must exist that the user is able to push container images to. This task will leverage the Azure Container Registry to either push a built runnable application image to and/or deploy a Container App from.

The name of the Azure Container Registry is required via the acrName argument.

The user can also provide values for the acrUsername and acrPassword arguments that will authenticate calls to the Azure Container Registry instance; if not provided, an access token will be generated via the Azure CLI that will authenticate the calls instead.

Azure Container App environment

An Azure Container App environment is recommended to have been previously created by the user to improve the performance of the task. If no environment has been created before, or if an environment cannot be found in the resource group that is being used to host the created Container App, then an environment will be created by as a part of the az containerapp up command, which may take additional time.

Examples

The following examples outline how to use the AzureContainerApps in different scenarios.

Minimal - Build application image for Container App

steps:
- task: AzureContainerApps@1
  displayName: Build and deploy Container App
  inputs:
    connectedServiceNameARM: 'azure-subscription-service-connection'
    appSourcePath: '$(System.DefaultWorkingDirectory)'
    acrName: 'mytestacr'

This will create a new Container App named ado-task-app-<build-id>-<build-number> in a new resource group named <container-app-name>-rg. The Container App will be based off of an image that was built from the provided appSourcePath and pushed to the provided ACR instance. An access token will be generated to authenticate the push to the provided ACR instance.

Minimal - Use previously published image for Container App

steps:
- task: AzureContainerApps@1
  displayName: Build and deploy Container App
  inputs:
    connectedServiceNameARM: 'azure-subscription-service-connection'
    imageToDeploy: mcr.microsoft.com/<existing-image>:latest

This will create a new Container App named ado-task-app-<build-id>-<build-number> in a new resource group named <container-app-name>-rg where no new image is built, but an existing image named mcr.microsoft.com/<existing-image>:latest will be used for the Container App.

Minimal - Use YAML configuration file with previously published image for Container App

steps:
- task: AzureContainerApps@1
  displayName: Build and deploy Container App
  inputs:
    yamlConfigPath: simple-image-container-app.yaml

This will create a new Container App named ado-task-app-<build-id>-<build-number> in a new resource group named <container-app-name>-rg where no new image is built, but an existing image named mcr.microsoft.com/<existing-image>:latest will be used for the Container App. Additional properties about the Container App will be pulled from the simple-image-container-app.yaml file and will override any additional values that would've been provided to the task as arguments excluding resourceGroup.

The simple-image-container-app.yaml file has the following structure:

properties:
  managedEnvironmentId: /subscriptions/SUBSCRIPTION_ID/resourceGroups/RESOURCE_GROUP/providers/Microsoft.App/managedEnvironments/CONTAINER_APP_ENVIRONMENT
  configuration:
    ingress:
      external: true
      allowInsecure: false
      targetPort: 80
  template:
    containers:
      - image: mcr.microsoft.com/<existing-image>:latest
        name: mysampleimagecontainer

The values for SUBSCRIPTION_ID, RESOURCE_GROUP and CONTAINER_APP_ENVIRONMENT must be updated to point to the full resource ID of the existing Container App environment that the Container App will use.
