- May 10, 2018 Next step in adding SSH credentials on Jenkins requires us to have the private ssh key for the server we want to connect with Jenkins server. So let’s take a scenario, we want to connect to a server from jenkins with user ‘Dan’.
- Jul 22, 2019 Jenkins fundamental architecture is ‘Master+Slave’ which is distributed in nature. Master is designed for co-ordination and handling tasks such as scheduling jobs, monitoring slave nodes, dispatching builds to slave nodes, recording and representing the build result and executing build jobs directly.
An SSH Key allows you to log into your server without needing a password. SSH Keys can be automatically added to servers during the installation process.
First, you can generate an ssh key from any account. That account just has to be able to access the Jenkins user%USERPROFILE%.ssh folder. Ssh-keygen -t rsa -P ' -f C: USers Jenkins Account.ssh idrsa Second, use JENKINS SSH Credentials Plugin in order to register your private key, and register the public key to the GitHub repo you monitor.
Creating an SSH key on Windows
The simplest way to create SSH key on Windows is to use PuTTYgen.
- Download and run PuTTYgen.
- Click the 'Generate' button.
- For additional security, you can enter a key passphrase. This will be required to use the SSH key, and will prevent someone with access to your key file from using the key.
- Once the key has been generated, click 'Save Private Key'. Make sure you save this somewhere safe, as it is not possible to recover this file if it gets lost
- Select all of the text in the 'Public key for pasting into OpenSSH
authorized_keys
file'. This is what you would need to enter into the control panel to use the SSH key.
Creating an SSH key on Linux
The tools to create and use SSH are standard, and should be present on most Linux distributions. With the following commands, you can generate ssh key.
- Run:
ssh-keygen -t rsa
. For a more secure 4096-bit key, run:ssh-keygen -t rsa -b 4096
- Press enter when asked where you want to save the key (this will use the default location).
- Enter a passphrase for your key.
- Run
cat ~/.ssh/id_rsa.pub
- this will give you the key in the proper format to paste into the control panel. - Make sure you backup the
~/.ssh/id_rsa
file. This cannot be recovered if it is lost.
Adding an SSH key to your control panel
- Once you're logged in, go to https://my.vultr.com/sshkeys.
- Click 'Add SSH Key'.
- Enter a descriptive name for the key.
- Paste in your SSH public key. This is a long string beginning with 'ssh-rsa'. You should have saved this from when you generated your key.
- Click 'Add SSH Key'.
- Now, when you're deploying servers you will be able to select which SSH keys you want to add to the newly deployed server. Remember to select the keys before the initial server deployment, otherwise you will need to log into the newly created server and add the SSH keys manually.
Limitations
- SSH keys are only available for Linux and FreeBSD. They are not supported for Windows, custom ISOs, nor snapshot restores.
- SSH keys can only be managed from the control panel during deployment. You cannot use the control panel to manage them on an already-installed instance.
Connecting to a server using an SSH key from a Windows client
- Download and run the PuTTY SSH client.
- Type the IP address or Username + IP address (
[email protected]
) of the destination server under the 'Host Name' field on the 'Session' category. - Navigate to the 'Connection -> SSH -> Auth' category (left-hand side).
- Click 'Browse.' near 'Private key file for authentication'. Choose the private key file (ending in
.ppk
) that you generated earlier with PuTTYgen. - Click 'Open' to initiate the connection.
- When finished, end your session by pressing
Ctrl+d
.
Connecting to a server using an SSH key from a Linux client
- Check that your Linux operating system has an SSH client installed (
which ssh
). If a client is not installed, you will need to install one. - Initiate a connection:
ssh -i /path/to/id_rsa [email protected]
- When finished, end your session by pressing
Ctrl+d
.
This quickstart 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
- An Azure subscription
- Access to SSH on your computer's command line (such as the Bash shell or PuTTY)
If you don't have an Azure subscription, create a free account before you begin.
Create the Jenkins VM from the solution template
Generate rsa key linux. 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.
- In your browser, open the Azure Marketplace image for Jenkins.
- Select GET IT NOW.
- After reviewing the pricing details and terms information, select Continue.
- Select Create to configure the Jenkins server in the Azure portal.
- In the Basics tab, specify the following values:
- Name - Enter
Jenkins
. - User name - Enter the user name to use when signing in to the virtual machine on which Jenkins is running. The user name must meet specific requirements.
- Authentication type - Select SSH public key.
- SSH public key - Copy and paste an RSA public key in single-line format (starting with
ssh-rsa
) or multi-line PEM format. You can generate SSH keys using ssh-keygen on Linux and macOS, or PuTTYGen on Windows. For more information about SSH keys and Azure, see the article, How to Use SSH keys with Windows on Azure. - Subscription - Select the Azure subscription into which you want to install Jenkins.
- Resource group - Select Create new, and enter a name for the resource group that serves as a logical container for the collection of resources that make up your Jenkins installation.
- Location - Select East US.
- Select OK to proceed to the Additional Settings tab.
- In the Additional Settings tab, specify the following values:
- Size - Select the appropriate sizing option for your Jenkins virtual machine.
- VM disk type - Specify either HDD (hard-disk drive) or SSD (solid-state drive) to indicate which storage disk type is allowed for the Jenkins virtual machine.
- Virtual network - (Optional) Select Virtual network Fifa 15 cd key generator download. to modify the default settings.
- Subnets - Select Subnets, verify the information, and select OK.
- Public IP address - The IP address name defaults to the Jenkins name you specified in the previous page with a suffix of -IP. You can select the option to change that default.
- Domain name label Rosetta stone mac download help. - Specify the value for the fully qualified URL to the Jenkins virtual machine.

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.![Windows generate ssh key jenkins user login Windows generate ssh key jenkins user login](/uploads/1/3/3/2/133278718/345318326.png)
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.
![Windows Generate Ssh Key Jenkins User Windows Generate Ssh Key Jenkins User](/uploads/1/3/3/2/133278718/495782858.jpg)
Unlock the Jenkins dashboard for the first time using this initial password.
Select Install suggested plugins on the next page and then create a Jenkins admin user used to access the Jenkins dashboard.
