Environment:

Yugabyte Platform

Issue:

It is required to provide the SSH keys while configuring the provider for creating the universe. Below screenshot shows the UI :

Once the provider is configured and saved:

Below screenshot shows that the task for universe creation failed after all the desired inputs are provided in the universe creation page:

Resolution :

In order to find out regarding the details of the failure, please check the yugaware logs.

ValueError: RSA key format is not supported

The SSH private key provided while creating the provider needs to be in the RSA format.

Please use the following command to convert the ssh private key into RSA format from OPENSSH format:

       ssh-keygen -p -N "" -m pem -f /path/to/key

Here;

 ssh-keygen -- is the command to convert the format of key

-f <input format> --- shown in above command

-m 'PEM indicates a PEM filetype

Note: It will change the file in place, so make a backup of your current key just in case. -N "" will set the passphrase as none. 

The public key should be fine as is.
