Thank you for the scripts you have shared. Really appreciated. It has helped set up Jenkins on docker with pre-configured plugins, jobs, and credentials.

Thank you, it helped a lot!

Can you please tell me how can I pass the key as a variable?
As it's a private key , i couldn't used directly as in code.
Please any one

Hi @AtibJunaid,

Do you mean environment variables or arguments? If it is the first, you can check it on this thead; https://stackoverflow.com/questions/40215394/how-to-get-environment-variable-in-jenkins-groovy-script-console

Hello @ivan-pinatti
Thank you for your response.
Iam using shell command to create public key and private key.
And I am adding public key to GitHub using api.
And I want to create a Jenkins credentials with private key.
Here in above code the private key is added in the script itself.
Due to security I can't add the key directly here in the script.
So I wanted to know how can I add private key .
In pipeline iam using
Stage(add private key){
Code = load 'ssh.groovy'

You can inject through an environment variable and then use it. If I am understanding what you are trying to achieve @AtibJunaid .

Do you anything where we can scope the credential to Folder level.

Do you anything where we can scope the credential to Folder level.

Sorry, I didn't understand your question @CondehA . Could you please elaborate more?

in this code we are making global credentials , I want to make it scoped to folder level so only folder jobs can access these credentials.

@CondehA, I never done on the folder level, but it mustn't be that hard.

Probably some adjustments and testing on this code you can achieve it.

Try changing line 42 where the domain is set, and also line 49.

If it doesn't work, try exploring reading the class documentation here.

I hope it helps.

Cheers!

Hello @ivan-pinatti
Thank You for the script, it really works.
I also used updateCredentials(domain, currentkey, newkey)
so it also works.

Hi @AtibJunaid,

That's good to hear.
Consider sharing the update script in your Gist and putting a link here so others can benefit from it as well. 😉

In addition, consider buying a simple coffee as I do these on my free time; https://www.buymeacoffee.com/ivan.pinatti
