Encountering InvalidImageRegistryPassword when attaching Log Analytic Workspace to my Container Instance

Question

Encountering InvalidImageRegistryPassword when attaching Log Analytic Workspace to my Container Instance

Jorgen Josef Martin (SRE) 0

I cannot attach my Log Analytic Workspace to my Azure Container Instance

Error shown below

The password in the 'imageRegistryCredentials' of container group 'my-container' cannot be empty.

My container is still running and pulling images successfully in my ACR.

upon using the command for getting imageregistry credentials it shows that the password is "null"
Is there a way to resolve this with redeploying the container

Hi @Akshay kumar Mandha

Yes, There is already an existing Container. I tried to attach the log analytic workspace but results to "Deployment Failed" and when checking the error mentioned above is the reason

I also tried the following troubleshooting

Enable Managed Identity

but when using the command to show Image Registry credentials container shows password is "Null" even though the Managed Identity is already enabled

Also checked that the Container is in Subscription A and the Container Registry that the container is pulling image from is in Subscription B. I was trying also to recreate /clone the container manually but since the registry and container are in 2 different subscription it the registry does not show in the options

Hi Jorgen Josef Martin (SRE),
Thanks for information.
Could you please check that the Azure Container Registry ACR in Subscription B is accessible from the Azure Container Instance in Subscription A. Assign the AcrPull role to the Managed Identity of the container in Subscription A for the ACR in Subscription B. from subscription a to subscription b

https://learn.microsoft.com/en-us/azure/role-based-access-control/permissions/containers

once again re apply managed Identity or switching to a user Assigned Managed Identity
