Description

Outline the issue here:
Unable to obtain kubectl config in latest version of CLI

Works in older version: pip install azure-cli-acs==2.0.16

Trace:

Confirmed for Azure CLI 2.0.19 and ACS version 2.0.17

rushsteve1 · 2017-10-17T21:23:46Z

Also confirmed. Azure CLI 2.0.19 and ACS version 2.0.17

doggy8088 · 2017-10-18T11:10:07Z

I find out a workaround for this issue. Just install the latest az-dev version solved my problem. Here is the steps to workaround this:

Install Python
choco install python -y
Install pip
wget https://bootstrap.pypa.io/get-pip.py
python get-pip.py
Install the latest Azure CLI 2.0 using pip
pip install --pre azure-cli --extra-index-url https://azurecliprod.blob.core.windows.net/edge

buzzfrog · 2017-10-18T11:13:45Z

A workaround is also to do it manually:
mkdir $HOME/.kube
scp azureuser@{master-dns-name}:.kube/config $HOME/.kube/config

AlexeyAtIgloo · 2017-10-18T13:14:07Z

Downgrading just ACS package after installing full cli also works: pip install azure-cli-acs==2.0.16

bacongobbler · 2017-10-18T15:19:50Z

It looks like this was fixed relatively recently: 5b4a0db

See #4646 for ways to install the bleeding edge of azure-cli.

same happening with CLI 2.0.19

rjtsdl · 2017-10-24T18:24:06Z

@troydai it should be fixed now. We can close this.

derekbekoe · 2017-10-24T18:26:38Z

2.0.20 has been released.

Thanks guys! Just tested un 2.0.20, works great!

@jamoham that's a different issue (socket.timeout). Sounds like your Kubernetes master is unreachable, try to establish a SSH connection using plain OpenSSH to confirm that (ssh [email protected]).
