@mjaow , We are looking into this query and will update you as soon as possible.

@mjaow The problem could be that when making a GET request to the containerGroups endpoint, the value for properties.ipAdress.ip is missing. (ref: https://docs.microsoft.com/en-us/rest/api/container-instances/containergroups/get)

Can you confirm whether the IP Address continues to be missing on subsequent calls to the REST API after first observing the missing value?

[mjaow]

Sorry I'm not sure.It's our customers service not mine.But from the logs,it only shows very few times.

I'm wondering if the vm host that container is crashed.Would it leading to the missing of IP

@mjaow Is there a way for you to get this detail from your customer?

Another relevant consideration is that the IP address of a container group is not guaranteed to remain static for the lifetime of the resource. It is recommended to use DNS name as the reliable method of permanently addressing the container.

I close it first.If there is more cases and more info.I'll open a new issue to discuss
