az network bastion ssh command fails #28339

Open gdebezpredel opened 9 months ago

gdebezpredel commented 9 months ago

Describe the bug

I'm trying to set up Bastion with AAD based login following this guides: 1, 2. After setting everything up the command fails. And the error is different depending on whether I use Azure Cloud Shell or local Azure CLI.

Related command

az network bastion ssh --name $name --resource-group $rg --target-resource-id /subscriptions/$sub/resourceGroups/$sub/providers/Microsoft.Compute/virtualMachineScaleSets/test-vmss/virtualMachines/0 --auth-type AAD

Errors

Azure Cloud Shell:

(AuthorizationFailed) The client '' with object id '' does not have authorization to perform action 'Microsoft.Network/bastionHosts/read' over scope '/subscriptions/sub/resourceGroups/rg/providers/Microsoft.Network/bastionHosts/host' or the scope is invalid. If access was recently granted, please refresh your credentials.

Thank you for opening this issue, we will look into it.

gdebezpredel commented 9 months ago

Update: I was able to get past these errors by fixing 2 things:

  1. setting the correct subscription on azure cli az account set --subscription "subscription"
  2. Fixing /etc/hosts file by adding a 127.0.0.1 localhost entry. It had 127.0.0.1 kubernetes.docker.internal instead because of docker desktop But I'm still seeing an error, though it's different:
