Description

I have setup kubenetes cluster in Azure using az acs command, it all worked until when I tried to connect

az acs kubernetes get-credentials --name=<clustername> --resource-group <resourcegroup>

[Errno 2] No such file or directory: ‘/root/.ssh/config’ Traceback (most recent call last): File “/usr/local/lib/python3.5/site-packages/azure/cli/main.py”, line 36, in main cmd_result = APPLICATION.execute(args) File “/usr/local/lib/python3.5/site-packages/azure/cli/core/application.py”, line 212, in execute result = expanded_arg.func(params) File “/usr/local/lib/python3.5/site-packages/azure/cli/core/commands/init.py”, line 377, in call return self.handler(*args, **kwargs) File “/usr/local/lib/python3.5/site-packages/azure/cli/core/commands/init.py”, line 626, in _execute_command reraise(*sys.exc_info()) File “/usr/local/lib/python3.5/site-packages/six.py”, line 693, in reraise raise value File “/usr/local/lib/python3.5/site-packages/azure/cli/core/commands/init.py”, line 603, in _execute_command result = op(client, **kwargs) if client else op(**kwargs) File “/usr/local/lib/python3.5/site-packages/azure/cli/command_modules/acs/custom.py”, line 814, in k8s_get_credentials _k8s_get_credentials_internal(name, acs_info, path, ssh_key_file) File “/usr/local/lib/python3.5/site-packages/azure/cli/command_modules/acs/custom.py”, line 835, in _k8s_get_credentials_internal ‘.kube/config’, path_candidate, key_filename=ssh_key_file) File “/usr/local/lib/python3.5/site-packages/azure/cli/command_modules/acs/acs_client.py”, line 63, in secure_copy conf.parse(open(ssh_config_file)) FileNotFoundError: [Errno 2] No such file or directory: ‘/root/.ssh/config’
