Due to fail to install on Azure, all the test related to Azure specific feature is blocked. Such as Azure disk, Azure file and so on I'd like to remove the TestBlocker key word since we figured out that we need to create the internal host name on Azure firstly and then create VM. Like below: az network nic create --resource-group xxx --name qe-internal-ip --vnet-name qe-vnet --subnet default-subnet --internal-dns-name qe-internal-hostname --public-ip-address qe-public-ip But I think this is something we need to doc and explain the new change since it worked in 3.7 before without --internal-dns-name. Thanks Hi Wenqi, are you saying this is documentation only issue? Or is there something else that needs to be resolved (given the priority is still high)? Scott, do we have already a place in openshift docs for the Azure cloud provider where we could put the note? I think it is doc related issue for 3.9 and above, without internal hostname, the installation will fail, and I do not think openshift-ansible can help modify something to fix this, it should notice user when they create vms need to set --internal-dns-name on network interface. Moving to Documentation component. |
