knife bootstrap aksing password, even if -P option is not provided #9675
Comments

@yogeshlc Thanks for reporting the issue. Seems this is the intended behavior of the bootstrap process first it will prefer keys, falling back to password. |
|
@vsingh-msys Yaa....that may be true. |
|
If No authentication needed then don't need to mention (-i or -P) it will bootstrap the node without fail... |
|
That's what I have mentioned in the bug .... Even if no -i or -P option mentioned knife bootstrap is failing with authentication error. |
|
Bug #8821 and MR #8856 is similar to the issue I am facing. |
|
It's better to provide the debug here.. using Also How you manage to login into node over ssh? |
|
Yes I am able to login using ssh into the node without any key or password. |

knife bootstrap aksing password, even if -P option is not provided.
eg.
knife bootstrap -U test1 --sudo 10.0.80.1 -F text -N ABCNode --bootstrap-template ~/abc/templates/chef-client-install.erb -E ABCEnv
it prompts:
