+1 on the same issue, same stack trace.

Installed via MSI, azure-cli (2.0.19), Windows 10 current build + Docker stable, running on CMD. Actually, I just installed azure-cli v2 from latest bits on MS website.

Disclaimer: I'm MS FTE, if you need a repro from a live computer

I am looking this. I may contact @vcx, but let me take a look first. :)

This has all our deployments completely blocked.

How do I install that a specific version of the Azure CLI? We are using this from the Azure documentation:

echo "deb [arch=amd64] https://packages.microsoft.com/repos/azure-cli/ wheezy main" | tee /etc/apt/sources.list.d/azure-cli.list
apt-key adv --keyserver packages.microsoft.com --recv-keys 417A0893
apt-get -qq update && apt-get -qq install azure-cli

You can down from https://packages.microsoft.com/repos/azure-cli/pool/main/a/azure-cli/ and then install manually. Would recommend removing the current version first.

e.g.

wget https://packages.microsoft.com/repos/azure-cli/pool/main/a/azure-cli/azure-cli_2.0.19-1_all.deb
dpkg -i azure-cli_2.0.19-1_all.deb

@rjtsdl can we close this issue?

troydai on 12 Oct 2017

I cannot close :)

rjtsdl on 12 Oct 2017

thanks @rjtsdl when applying your changes locally it worked :)

A workaround. Use 'az acs list' to get the 'masterProfile' 'fqdn' value and insert below for 'master-fqdn'. The following two commands should perform the action to copy down the config file from the cluster master node which 'az acs kubernetes get-credentials' is failing to perform. I tested this locally and it's working for me.

mkdir $HOME/.kube
scp azureuser@<master-fqdn>:.kube/config $HOME/.kube/config

This worked for me also...thanks a lot...you don't have to get the credential using get command in this case...

sanjshah2001 on 16 Oct 2017

FWIW this is still erroring when using Azure Cloud shell, but naustin's workaround works ok.

raesene on 17 Oct 2017

Same problem, scp workaround successful. Did not have this issue on windows, only on ubuntu.

fh0k on 18 Oct 2017

Just created a kubernets via azure-cli on azure portal. I get the same config missing error. But the scp workaround does not work. It returns permission denied. The public key on returns from az acs list is the same as at $HOME/.ssh/id_rsa.pub

any ideas?

Additional information:

1.azure-cli 2.0.19

tested on 23/10/2017
python 3.6.1

The next release azure-cli==2.0.20 will contain the fix in the ACS. The release will happen on Tuesday (10/24) in all channels including cloud shell.

troydai on 23 Oct 2017
