Hostname does not match the server certificate


#1

Hi all,

My chef-server is COMPUTE1 (in capital letters) and workstation is COMPUTE2 (in capital letters) and I am trying to upload a cookbook to the server.

user@COMPUTE2:~/chef-repo$ sudo knife cookbook upload sudo
Uploading sudo         [0.1.0]

Use `knife ssl check` to troubleshoot your SSL configuration.
If your Chef Server uses a self-signed certificate, you can use
`knife ssl fetch` to make knife trust the server's certificates.

I tried knife ssl check and it returns everything is ok.

user@COMPUTE2:~/chef-repo$ sudo knife ssl check
Connecting to host COMPUTE1:443
Successfully verified certificates from `COMPUTE1'
user@COMPUTE2:~/chef-repo$ 

knife ssl fetch is working fine too

user@COMPUTE2:~/chef-repo$ sudo knife ssl fetch 
WARNING: Certificates from COMPUTE1 will be fetched and placed in your trusted_cert
directory (/home/user/chef-repo/.chef/trusted_certs).

Knife has no means to verify these are the correct certificates. You should
verify the authenticity of these certificates after downloading.

Adding certificate for COMPUTE1 in /home/user/chef-repo/.chef/trusted_certs/COMPUTE1.crt
user@COMPUTE2:~/chef-repo$ 

My hostnames are in capital letters. Is that the reason why this is not working? I am unable to change the hostname because of some application compatibility/limitations. Could someone please help.

Thanks,

Hey even I’m facing the same issue, if you have resolved the issue please share your solution here

You might have to add this to your knife.rb file:
trusted_certs_dir /path/to/trusted_certs

Mine looks like this:
trusted_certs_dir ["#{current_dir}/trusted_certs"]
