在Azure上的托管Chef服务器上引导EC2实例时出错

Question

I am trying to bootstrap ec2 instance using knife on chef server hosted on azure marketplace. the chef client run fails throwing the following error.

PS C:\Users\xyz\chef-repo> knife ec2 server create -I ami-25c00c46 -f t2.micro 
--region ap-southeast-1 -N ec2module
-x ubuntu -i abc.pem -r "role[ec2], role[jenkinserver]" -g sg-9f1b31fa sudo

.ap-southeast-1.compute.amazonaws.com Chef encountered an error attempting to create the client "ec2module"

Answer 1

There seems to be a problem with the server SSL certificate and perhaps it is related to Chef issue #4301 (read it).

Try downloading the SSL certificate from the Chef Server :

> knife ssl fetch

Then, you can check it with :

> knife ssl check

I hope this helps.
