无法将卷连接到 Azure 容器实例

Question

I tried to deploy my Rasa chatbot in an Azure Container Instance using a YAML file and Azure CLI. Although it runs smoothly locally using the local wsl2 volume path /var/lib/docker/volumes/, when in cloud it appears to have the following problem.

Inside the rasa/rasa:3.xx image there is a dockerfile layer that creates a Volume /tmp that contains metadata and python autographs. But when I upload the image to the cloud, while it seems that there is a connection with Azure File Share, this /tmp folder is NOT created. As you can see in the images below, inside the properties of the ACI, the File Share volume appears to function well.

ACI with Azure File Share connection

Empty Azure File Share directory

Docker VOLUME [/tmp] layer

Below is my deploy-aci.yml used for the: az container create --resource-group --file deploy-aci.yml

Is there something i am missing about mounting a File Share volume to a Linux Azure Container Instance?

I have already read the documentation about mounting with Azure File Share https://docs.microsoft.com/en-us/azure/container-instances/container-instances-volume-azure-files

Any help is appreciated!

Answer 1

But when I upload the image to the cloud, while it seems that there is a connection with Azure File Share, this /tmp folder is NOT created.

the /tmp folder is mapped with your host even you are taking image of that running container you won't able save that /tmp folder as image and can't able to see in the Azure Container Instance.

Only Partition or folder which you have created for local container can able to see in Azure Container Instance because they are not mapped/attached with your host.

Another more important things be notice apart from above suggestion

If you mount a share into a container directory in which files or directories exist, the mount obscures files or directories, making them inaccessible while the container runs.
