Private key secret : I also set the user'password as this property. it's not work also

The private key secret should be specified as name of a job secret whose value is your private key. Check the inline help of that property.

I did it this way, just omitted to describe job secret. My main point is that I don’t know if the value of the job secret is something like this: -----BEGIN OPENSSH PRIVATE KEY----- my private key -----END OPENSSH PRIVATE KEY----- or it can also be done using a password.

Or, how can I retrieve the text value of the private key?

The value should be content of a private key. Please make sure your private key can be used to login to remote machine. You may also test directly with image 1dev/ssh-client:1.0.0 and run same commands as the step to find out why it is not working:

Thank you, I will check.

I find the problem.

We have set a passphrase for the private key we are using, and we utilize ssh-agent to avoid frequently entering the passphrase. Could you please advise on how to support passphrases or ssh-agent in this context?

Unfortunately private key with passphrase is not supported.

As far as I know, many system administrators set a passphrase for their private keys. If passphrases are not supported, the functionality of this feature will be significantly compromised. Please reconsider supporting this capability.

This will not be considered right now, as supporting passphrase can be quite complex. Closing the issue now.
