I am trying to program a pipeline that requests a username and password as parameter to connect via ssh to a linux server.
I have searched the internet for solutions but the SSH Agent plugin only works with credentials stored in Jenkins.
Is it possible to create a credential with the parameters sent by the user that executes the pipeline or use them as credentials?
Thanks!

Having issues creating an ssh credential in Jenkins that allows access to GitLab. I have 2 AWS instances, one with GitLab and one with Jenkins. I would like to setup a multibranch pipeline in Jenkins to run a GitLab repo. I am able to create the pipeline and can access GitLab if I use a username/password credential (using "root"/initial password) but would like to use the more secure route of using a username/SSH credential. I have generated the SSH (of the ed25519 variety) in the GitLab instance (while in root). Then, in GitLab, supplied the public key to the root user. Then, in Jenkins, provided the private SSH key and set username as "root" in a username/SSH credential. When I try to run the pipeline using the username/SSH credential I get an error indicating that it is not authorized. Should I be using a different username? Should I be generating the SSH key in a different location?
Well, I figured it was something small I was missing. I was configuring the pipeline job for the http url of the repo rather than the SSH url. Once I changed that, it worked right away.
I am using bitbucket cloud and jenkins is running on ec2 instance on the private network.
Connection is well established between bitbucket and jenkins as when i run the job manually, the job shows the green status. However when i made the changes in the repo and it gets merged the webhook is not using my app password and as a result the job is getting failed.
I am getting authentication failed and It's basically asking me to use the app password. I have already created it but still webhook is not using it. I am getting the response 200 now in webhook means my webhook is able to reach the jenkins server but i am not sure why i am getting authentication failed.
Can you confirm that:
Your credentials are correctly placed under the credentials section of Jenkins. The username should be the username of the account you are using, and the password should be the app password. It should be present like this:
The ID of the credentials should be used within your pipeline script anywhere you want access to the Bitbucket repository.
Ensure that Bitbucket has access to your EC2 instance that runs Jenkins.
Basically, these are the 3 points where authentication can fail. Checking each point should reveal the problem.
I'm new to Jenkins world, I have a usecase where I have setup a jenkins pipeline using JenkinsFile. As part of deployment stage, we will invoke a few ansible script in the backend to get the image deployed into Kubernetes cluster running in cloud environment. The script expects few secrets in environment variable, so I like to understand which is the best option to handle secret in Jenkins, do I need them to enter into jenkins credentials and read them in jenkins environment tag like below. Or It is safe to get the value from the user using input plugin when executing the pipeline, but if I get from user then I would not able to completely automate pipeline will wait until user input the secret. Could you help in safe way to handle credentials.
pipeline{
agent any {
environment {
SECRET_VALUE=credentials('SECRET_VALUE_FROM_JENKINS_CREDENTIALS')
}
}
}
It depends on your use case, Indeed both approaches as you mentioned above will work.
There shouldn't be any problem in keeping your secrets as Jenkins credentials, in my case, all my secrets are in the Hashicorp vault and my Jenkins credentials point to the vault location as an example...
- usernamePassword:
scope: GLOBAL
id: serviceUser
username: svc_admin
password: "${secret/xyz/service_user/password}"
description: My secret service user
The Jenkins deployment is via JCasC.
As jenkins admin I can say it is safe to store credentials in jenkins.
Just create credentials in jenkins and use in a pipeline. Also it's nice to have mask password plugin installed in jenkins, which will mask credentials in jenkins jobs' output.
I want to use scp/ssh to upload some files to a server. I discover that I need to use certificate-based authentication, but the question is how? Really what I want to do is to use the same sort of credentials I use with git - passworded ssh cert stored in Jenkins. However, I can't work out how to - the snippet generator has no obvious option for that.
What do others do? Is there an undocumented feature that would do this?
withCredentials([sshUserPrivateKey(credentialsId: "yourkeyid", keyFileVariable: 'keyfile')]) {
stage('scp-f/b') {
sh 'scp -i ${keyfile} do sth here'
}
}
Maybe this is what you want. Install Credentials Plugin and
Credentials Binding Plugin. Add some credentials and then you will get "yourkeyid", bind this credentials to keyFileVariable, passphraseVariable etc.
More details and documentation can be found on the Github site of the Jenkins Credentials Binding Plugin, Credentials Binding Plugin docs, Credentials Plugin, SSH Pipeline Steps plugin
If you install the SSH Agent plugin you can use the ssh-agent pipeline step to run a shell script with an ssh-agent active. The ssh-agent takes a Jenkins credentials ID (a passworded ssh cert, like the one you have for git).
I am trying to integrate Bitbucket on cloud and Jenkins on premise, but once I enter the IP of my local Jenkins in Bitbucket cloud it show error URL not valid.
Is there a way to solve this, or do I need to buy Jenkins cloud license?
Your local Jenkins server is not seen by a cloud Bitbucket server because it is an internal server.
You can solve it in one of those alternatives:
Ask your system administrator to expose your Jenkins server with a global IP address along with the Jenkins port (e.g. 8080) so the Bitbucket server will be able to access it. This is not totally secure due.
Activate the Jenkins job that pulls from the remote BitBucket server on time internal - in the Job 'Build Triggers' section check the 'Poll SCM' checkbox and set the cron setting (for example: 'H/15 * * * *' for building every 15 minutes. Notice that it will not build if there were no code changes)
