How to mount a volume when building a pipeline in DevOps to deploy to Container Apps.

Ada Graves 0

I have a Container registry, a Container Apps Environment, and a Container App. I set up a Storage account with a File share. I added the file share to my Container Apps Environment. I added a Volume to my Container App that references the file share. I'm using a pipeline in Azure DevOps to build the container and push it the registry and run a containerapp update so it creates a new revision. And no matter how I configure my docker-compose.yml file, I can't seem to get Azure to actually mount the volume to my revisions. I tried downloading the app.yaml file and adding a mount there, as per the container apps documentation. I've tried any number of solutions of formatting the volume in docker-compose per questions I've found here and on StackOverflow. Nothing seems to work. In the Volumes tab on my Container App I get a message that says: "The following volumes have no associated mounts in this revision's containers:".

Hi

While understood your scenario, do you have any error code?

Are you running this for training?

Hello

Welcome to the Microsoft Q&A and thank you for posting your questions here.

Problem

Sequel to your questions, I understand that you are facing challenges to attach a volume to your Container App in Azure DevOps. Despite creating a Storage account with a File share, integrating the file share into the Container Apps Environment, and setting up a volume in her Container App, yet still facing problems while deploying via the Azure DevOps pipeline. Despite trying several times and tweaking configurations, Azure isn't able to link the volume to the Container App revisions.

Scenario

A user is managing a Container Apps Environment in Azure and is utilising Azure DevOps pipelines for CI/CD. They recently established a Storage account with a File share to store persistent data for their Container App. Following Azure documentation, they successfully added the file share to their Container Apps Environment. Subsequently, they configured a volume in their Container App, referencing the file share. They then set up an Azure DevOps pipeline to build the container image, push it to the Container Registry, and trigger a container app update for deployment.

Solution

This prescribed solution was based on the scenario given and your questions, while focusing on the problem statement. There are three things I will suggest but before you go ahead, check your configuration that your file share is enable as shown in the fig. below:

Also, ensure you have all the details of the storage account.

Now, DOCKER-COMPOSE

In your docker-compose.yml file, ensure that you correctly define the volume to be mounted. Here's an example configuration:

version: '3' services: your_service_name: image: your_image_name volumes: - SHARF1Dc:/path/in/container volumes: your_volume_name: external: true

Replace SHARF1Dc, your_image_name, and /path/in/container with your specific value.

AZURE DEVOPS PIPELINE

Then, in your Azure DevOps pipeline ensure your Azure DevOps pipeline is configured to build the Docker image and push it to your Azure Container Registry. Include the necessary steps in your pipeline YAML file to achieve this. Here's a simplified example:

steps:

- task: Docker@2 inputs: containerRegistry: 'your_container_registry_connection' command: 'buildAndPush' Dockerfile: '**/Dockerfile' tags: 'your_image_tag'

Replace your_container_registry_connection and your_image_tag with your specific values.

APP YAML FILE

The next is to get your app.yaml file. In your app.yaml file, accurately specify the volume mount configuration. For example,

apiVersion: 2023-11-01-prev kind: App metadata: name: your_container_app_name spec: containers: - name: your_container_name image: your_image_reference volumes: - name: SHARF1Dc azureFile: shareName: your_share_name storageAccountName: sharf1 storageAccountKey: your_storage_account_key readOnly: false

Ensure your_container_app_name, SHARF1Dc is an example of your_volume_name, sharf1 is an example of your_storage_account_name, your_container_name, and other parameters match your Azure setup.

Mount Volume if not.

To mount the volume or check your configurations, check this link: Mount Azure Storage as a local share - Azure App Service

Finally

If you can follow the above steps, I assure you 90% success.

However, if deployment fails or the volume isn't mounted as expected, check Azure DevOps pipeline logs for errors. Common issues might include incorrect volume or storage account configurations. Also, ensure the Azure Storage account, file share, and Container App are in the same region and subscription and verify that your Azure permissions allow mounting volumes.
