You do not have to generate or keep track of any new keys. There is no key management; users have the same permissions on the server that they do locally. No keys are stored on the server, so in case the server is compromised, you don't need to hunt down and remove the compromised keys. To specify the SSH key in the Git step. When the Jenkins server is operational, navigate to the Web interface. Create a new Jenkins project. In the Source Code Management section Select Git. Enter the SSH URL of the repository. When you are adding the first project, click the Add button to create the credential. Generate SSH Key. We will be using the ssh key authentication to setup our agent nodes, so we need to generate the ssh key for the Jenkins user and then upload the key to each server node manually using 'ssh-copy-id'. On the Jenkins master server, login to the Jenkins user and generate the ssh key. Su - jenkins ssh-keygen. May 10, 2018 Learn how to make a ssh connection from Jenkins Server to a remote server & add ssh credentials on Jenkins Server. Jenkins can make ssh connection to a remote server for the purpose of executing a command or running a script or we can also copy file from jenkins or some other server to another. Oct 20, 2014 The public key is uploaded to a remote server that you want to be able to log into with SSH. The key is added to a special file within the user account you will be logging into called /.ssh/authorizedkeys. When a client attempts to authenticate using SSH keys, the server can test the client on whether they are in possession of the private key.
This tutorial shows how to install Jenkins on an Ubuntu Linux VM with the tools and plug-ins configured to work with Azure. When you're finished, you have a Jenkins server running in Azure building a sample Java app from GitHub.
Prerequisites
https://cleverky524.weebly.com/download-free-vmware-for-mac.html. If you don't have an Azure subscription, create a free account before you begin.
Create the Jenkins VM from the solution template
Jenkins supports a model where the Jenkins server delegates work to one or more agents to allow a single Jenkins installation to host a large number of projects or to provide different environments needed for builds or tests. The steps in this section guide you through installing and configuring a Jenkins server on Azure.
Connect to Jenkins
Navigate to your virtual machine (for example,
http://jenkins2517454.eastus.cloudapp.azure.com/ ) in your web browser. The Jenkins console is inaccessible through unsecured HTTP so instructions are provided on the page to access the Jenkins console securely from your computer using an SSH tunnel.
Set up the tunnel using the
ssh command on the page from the command line, replacing username with the name of the virtual machine admin user chosen earlier when setting up the virtual machine from the solution template.
After you have started the tunnel, navigate to
http://localhost:8080/ on your local machine.
Get the initial password by running the following command in the command line while connected through SSH to the Jenkins VM.
Unlock the Jenkins dashboard for the first time using this initial password.
Generate Key As Jenkins User Password
Select Install suggested plugins Pdf reader app for mac. on the next page and then create a Jenkins admin user used to access the Jenkins dashboard.
The Jenkins server is now ready to build code.
Create your first job
Select Create new jobs from the Jenkins console, then name it mySampleApp and select Freestyle project, then select OK.
Select the Source Code Management tab, enable Git, and enter the following URL in Repository URL field:
https://github.com/spring-guides/gs-spring-boot.git
Select the Build tab, then select Add build step, Invoke Gradle script. Select Use Gradle Wrapper, then enter
complete in Wrapper location and build for Tasks.
Select Advanced and then enter
complete in the Root Build script field. Select Save.
Build the code
Select Build Now to compile the code and package the sample app. When your build completes, select the Workspace link for the project.
Navigate to
complete/build/libs and ensure the gs-spring-boot-0.1.0.jar is there to verify that your build was successful. Your Jenkins server is now ready to build your own projects in Azure.
Troubleshooting the Jenkins solution template
If you encounter any bugs with the Jenkins solution template, file an issue in the Jenkins GitHub repo.

Jenkins acts as an SSH server, starting 1.446. This exposes a subset of Jenkins CLI commands (those that do not need any intelligence on the client side.) Plugins may also add additional capabilities through SSH server.
By default, Jenkins will listen on a random available port, so as not to break existing deployments. But this is most likely not very useful, so the administrator is encouraged to change this from the global security configuration page by assigning a fixed port. This configuration UI will also allow you to disable this feature.
On secured Jenkins, you register your public keys to Jenkins. See 'working with credentials' in Jenkins CLI for more details, and this is how you log in. On unsecured Jenkins, there's no authentication performed.
Use the 'who-am-i' command to verify who you are logging in as:
Both provide access to a set of commands that lets you interact with Jenkins from a command line, but they have a few differences:
A part of the SSH protocol involves in verifying that you are talking to the real Jenkins server, instead of a fake inserted by an attacker (otherwise known as the man-in-the-middle attack.) Instance Identity is used as the server key.
Jenkins Manage Users
Combined with HTTPS, this provides a trusted path to establish a secure connection from a client over an untrusted network.
Programs who wish to discover the SSH endpoint of Jenkins can do so by doing GET access on the Jenkins top page and look for the 'X-SSH-Endpoint' HTTP header in the response. This header has the value formatted as HOST:PORT that indicates where the SSH server is listening. This header is present even if the request itself fails (for example, due to access denied.)
Generate Key As Jenkins User Login
The host portion of the header is inferred automatically from the configured root URL, but administrators can override this value by setting the
org.jenkinsci.main.modules.sshd.SSHD.hostName system property. This is convenient if you run your Jenkins behind a reverse proxy and you need to route the SSH traffic differently.
