In a CI/CD environment,we can’t avoid dealing with any source code management system since it is integral part of a whole development cycle.
And we all know that git is the famous distributed version control system that has been widely adopted by many large opensource projects and almost all organisation that follow agile to deliver the service in the fast pace.
Solved: How do I set up ssh public-key authentication so that I can use ssh, sftp or scp from my Bitbucket Pipelines pipeline? Jun 13, 2019. SiteGround uses key-based authentication for SSH. This has proven more secure over standard username/password authentication. More information on SSH keys can be found here. You can generate an SSH key pair directly in cPanel, or you can generate the keys yourself and just upload the public one in cPanel to use with your hosting account.
There were projects,that has taken a git as base and built on top of it to offer a service to consider the enterprise approach and name few are gitlab,github and bitbucket.
Today i’m gonna show how you can interact with your hosted bitbucket account with most securely any Jenkins that use your source code either to build something or deploy.
I have taken a example java code and try to build it as jar file in the coming up.
To achieve this we require a SSH key pair,so i have used linux host to generate a new one and that is not limited if you want use any ssh software(ex:PuTTYgen) to create.
I should have two ssh keys in the directory following /root/jenkins_pub_priv_key_for_bitbucket/.ssh/ that include is id_rsa & id_rsa.pub.
A private key(id_rsa) saved to your Jenkins and a public key uploaded to Bitbucket. Bitbucket uses the key pair to authenticate anything the associated account can access. This two-waymechanism prevents man-in-the-middle attacks.
Let’s upload the private key in jenkins,navigate to Jenkins URL and following menu
Manage Jenkins –> configure credentials –> credentials –> system –>Add credentials.
change the credentials “kind” to “SSH Username with private key” in follow with username that is being used in the bitbucket account,private key and passphrase that used to unlock the private key.
Now add the public key to bit bucket,
Bitbucket –> settings –> security–>ssh keys –>add keys. /lineage-2-adrenaline-bot-key-generator.html.
We have setup our keys in both Jenkins and bitbucket,let see how we gonna using it.
There is java build project that gone use bitbucket source as mentioned ,i have chosen credentials that created just now before.
When i try to build ,you gonna see the interaction will happen over ssh and we safe enough to proceed further.
-->With a secure shell (SSH) key pair, you can create virtual machines (VMs) in Azure that use SSH keys for authentication, eliminating the need for passwords to sign in. This article shows you how to quickly generate and use an SSH public-private key file pair for Linux VMs. You can complete these steps with the Azure Cloud Shell, a macOS or Linux host, the Windows Subsystem for Linux, and other tools that support OpenSSH.
Note
VMs created using SSH keys are by default configured with passwords disabled, which greatly increases the difficulty of brute-force guessing attacks.
For more background and examples, see Detailed steps to create SSH key pairs.
For additional ways to generate and use SSH keys on a Windows computer, see How to use SSH keys with Windows on Azure.
Azure currently supports SSH protocol 2 (SSH-2) RSA public-private key pairs with a minimum length of 2048 bits. Other key formats such as ED25519 and ECDSA are not supported.
Use the ssh-keygen command to generate SSH public and private key files. By default, these files are created in the ~/.ssh directory. You can specify a different location, and an optional password (passphrase) to access the private key file. If an SSH key pair with the same name exists in the given location, those files are overwritten.
The following command creates an SSH key pair using RSA encryption and a bit length of 4096:
If you use the Azure CLI to create your VM with the az vm create command, you can optionally generate SSH public and private key files using the --generate-ssh-keys option. The key files are stored in the ~/.ssh directory unless specified otherwise with the --ssh-dest-key-path option. The --generate-ssh-keys option will not overwrite existing key files, instead returning an error. In the following command, replace VMname and RGname with your own values:
To create a Linux VM that uses SSH keys for authentication, specify your SSH public key when creating the VM using the Azure portal, Azure CLI, Azure Resource Manager templates, or other methods:
If you're not familiar with the format of an SSH public key, you can display your public key with the following cat command, replacing ~/.ssh/id_rsa.pub with the path and filename of your own public key file if needed:
A typical public key value looks like this example:
If you copy and paste the contents of the public key file to use in the Azure portal or a Resource Manager template, make sure you don't copy any trailing whitespace. To copy a public key in macOS, you can pipe the public key file to pbcopy. Similarly in Linux, you can pipe the public key file to programs such as xclip.
The public key that you place on your Linux VM in Azure is by default stored in ~/.ssh/id_rsa.pub, unless you specified a different location when you created the key pair. To use the Azure CLI 2.0 to create your VM with an existing public key, specify the value and optionally the location of this public key using the az vm create command with the --ssh-key-values option. In the following command, replace VMname, RGname, and keyFile with your own values:
If you want to use multiple SSH keys with your VM, you can enter them in a space-separated list, like this --ssh-key-values sshkey-desktop.pub sshkey-laptop.pub.
With the public key deployed on your Azure VM, and the private key on your local system, SSH into your VM using the IP address or DNS name of your VM. In the following command, replace azureuser and myvm.westus.cloudapp.azure.com with the administrator user name and the fully qualified domain name (or IP address):
If you specified a passphrase when you created your key pair, enter that passphrase when prompted during the login process. The VM is added to your ~/.ssh/known_hosts file, and you won't be asked to connect again until either the public key on your Azure VM changes or the server name is removed from ~/.ssh/known_hosts.
If the VM is using the just-in-time access policy, you need to request access before you can connect to the VM. For more information about the just-in-time policy, see Manage virtual machine access using the just in time policy.
