AZ-204 Exam - Question 37

Question

HOTSPOT-You are developing an application that includes two Docker containers. The application must meet the following requirements:•	The containers must not run as root. •	The containers must be deployed to Azure Container Instances by using a YAML file. •	The containers must share a lifecycle, resources, local network, and storage volume. •	The storage volume must persist through container crashes. •	The storage volume must be deployed on stop or restart of the containers. You need to configure Azure Container Instances for the application. Which configuration values should you use? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Ans: Container group, EmptyDir

Container group is the only logical answer that can have shared lifecycle https://learn.microsoft.com/en-us/azure/container-instances/container-instances-container-groups?source=recommendations#what-is-a-container-group
Azure files need root permission
Secret is for secrets and read-only
EmtyDir can persist through crash and redeployed on stop and restart

Cloned Git Repo also does the job but it needs more details like Git URL and stuff which are not mentioned to be available in the question

Could anyone give the correct answare. As it is quite confusing from the comments and multiple people having diff. options

nayru · Answer

Got on 26/09/23 and chose container group and empty dir (score 910)

narenazure · Answer

https://learn.microsoft.com/en-us/azure/container-instances/container-instances-volume-azure-files   here it is clearly mentioned Azure file share volume mount requires the Linux container run as root . so Azure file share is not an option

GuruPratap · Answer

Container Group, Azure fileshare
For Shared lifecycle, the appropriate configuration setting would be "Container Group," which allows multiple containers to be deployed together as a group and share a local network, storage, and lifecycle.

For Storage volume, the appropriate configuration setting would be "Azure file share," which provides a durable and highly available storage solution that can be mounted as a volume in the container instance. This ensures that the storage volume persists through container crashes and can be deployed on stop or restart of the containers.

Got this 2023-05-12.

my cases also:
case: You need to configure authorization.
case: You need to ensure the app does not time out and processes the blob data

sachinrikhe · Answer

Container Group is the only logical 
But storage volume should be azure file share
"Azure File Share allows the containers to share a persistent volume for storing data, and it can be mounted to the containers as a file system. It also provides a durable and highly available storage solution that persists through container crashes and can be deployed on stop or restart of the containers."
Cloned Git does not provide a mechanism for deploying the application or managing its dependencies.

Got this on 6/28/2023 and passed with 850.  Went with Container group, EmptyDir.

imanonion · Answer

Why isn't this Azure file share? Clone git repo is only available for Linux machines and this question did not specify Linux as a requirement..

Ar_priya · Answer

as the container instances must run as non root user, answer is definitely not file share.

"Azure file share volume mount requires the Linux container run as root ."

katrang · Answer

Shared Lifecycle - Container Group
Storage volume - The storage volume must persist through container crashes, so emptyDir meets the requirements

manopeydakon · Answer

Container Group, Azure fileshare, You can set the user and group IDs for each container in the Docker image to ensure they do not run as the root user. This is typically done using the USER instruction in the Dockerfile. Azure File Share can be mounted as a volume in each container to provide shared storage. With these modifications, your containers will run with non-root users, and they will share storage using an Azure File Share.

ChatGPT: Azure Container Group, Azure Fire Share

8ac3742 · Answer

The Storage Volume should Azure File Share, An Empty directory (or emptyDir) in Azure Container Instances is a type of ephemeral storage volume. 
An Empty directory provides a writable directory that is accessible to each container in a container group. When the container group is created, the directory is initially empty, hence the name "emptyDir"1.
Empty directories are commonly used for:
scratch space: Temporary storage for data that doesn’t need to persist beyond the container’s lifecycle.
Checkpointing: Storing intermediate results during long-running tasks.
Sidecar containers: Sharing data between a main application container and a sidecar container, such as logs or temporary files1.

dimsok · Answer

"The storage volume must persist through container crashes"  +
"The storage volume must be deployed on stop or restart of the containers." = "Cloned Git Repo"

AhmedAbdelAziz · Answer

Ans: Container group, EmptyDir
EmptyDir doesn't required run as root , also support data persistence throw container crashes although it doesn't grantee persist the data in a volume between restarts as there is no requirement like that

Kensington · Answer

Container group is the only logical answer, as mentioned by others.
Emptydir lifecycle is tied to the container group and therefore persists for individual container crashes.
GitRepo makes less sense as it's ready-only and is mostly used for scenarios where you want to load code into your app.

Storage volume:
✔ Answer: Azure file share

📌 Explanation: An Azure File Share provides persistent, durable storage that survives container crashes and restarts. This is the only option listed that fully meets the persistence requirement. Options like Empty directory are temporary and reset on restart.
