Authentication in Mongo DB is not working in Azure Container Instance when deploying with Azure File Share as mount volume

Question

I am deploying mongo db container as Azure container instance in a group using Azure CLI YAML script. Here I am using a Azure file share as a mount volume, while using this mount volume the authentication is not enabled in mongo db. Though without mount volume it is working fine. Here is my YAML script:

apiVersion: '2019-12-01'
location: southindia
name: xyz
properties:
  containers:
  - name: xyz-mongo
    properties:
      environmentVariables: 
      - name: MONGO_INITDB_ROOT_USERNAME
        value: xyz
      - name: MONGO_INITDB_ROOT_PASSWORD
        secureValue: xyz
      image: xyz.azurecr.io/xyz/mongo:4.2.8
      command: ['mongod', '--dbpath', '/data/mongoaz']
      ports:
      - port: 27017
      resources:
        requests:
          cpu: 1.0
          memoryInGB: 1.0
      volumeMounts:
      - name: xyzstore
        mountPath: /data/mongoaz
  osType: Linux
  restartPolicy: Always
  ipAddress:
    type: Public
    ports:
      - protocol: tcp
        port: 27017
    dnsNameLabel: xyz
  volumes:
  - name: xyzstore
    azureFile:
      sharename: xyz
      storageAccountName: xyz
      storageAccountKey: xyz
  imageRegistryCredentials:
  - server: xyz.azurecr.io

Answer 1

@Md Farman Khan Apologies for the delay in response and all the inconvenience caused because of the issue.

Mounting an Azure Files share to a container instance is similar to a Docker bind mount. Be aware that if you mount a share into a container directory in which files or directories exist, these files or directories are obscured by the mount and are not accessible while the container runs.

So it's not recommended to mount the Azure File Share to the existing directory which contains the files used to initialize the Mongo DB. The recommend directory will like path /var/logs/ which might be the reason you are not able to do so.

Hope it helps.

Do let me know if you have any further queries.

Hello @Md Farman Khan , Im having the same problem, you solved it? I am deploying a container with mongodb and API as Azure container instance but the authentication its not works. If you have some news about it, please share with me.

Answer 3

I had the same problem.
It turns out you have to run a script like the following:

mongo
use admin
db.createUser(
  {
    user: "mongo-admin",
    pwd: "-",
    roles: [{role: "root", db: "admin"}]
  }
)

I haven't figured out how to integrate this into an arm template yet.
