Github Generate Ssh Deploy Key

Posted on by

Because Travis CI can automatically execute scripts after successfully (or unsuccessfully!) executing tests, it is an obvious choice for a deployment tool. In order to deploy to a Git repository on a remote server, the process generally is as follows:

List deploy keys; Get a deploy key; Add a new deploy key; Edit a deploy key; Remove a deploy key; You can launch projects from a GitHub repository to your server by using a deploy key, which is an SSH key that grants access to a single repository.

  • Supported SSH key formats. 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. Create an SSH key pair. Use the ssh-keygen command to generate SSH public and private key files. By default, these files are created in the.

  • SSH Deploy Keys Walkthrough. If the instructions in Authentication: SSH Deploy Keys did not work for you (for example, ssh-keygen is not installed), don't worry! This walkthrough will guide you through the process. There are three main steps: Generating an SSH Key.

  • Set up SSH keys
  • Add the server's copy of the repository as a Git remote
  • Push to the remote
  • SSH into the server and execute any installation/compilation/miscellaneous commands

Before even touching .travis.yml..

Users

Git recommends using a separate git user for remote interactions. However, your repositories might be under a separate user (apps, for example), so you'll need to add both those users to a group (deploy, for example).

SSH keypair

Make sure to generate an SSH keypair for passwordless login! This can be done on from the commandline via ssh-keygen -t rsa (provided OpenSSH is installed, which it normally is for Linux and other emulation layers like Git Bash) or through GUI tools like PuTTYgen. It does not matter where you generate the keys. When prompted for a passphrase, make sure to leave it blank so that Travis can automatically login. Make note of where the keys are generated. Now use either the ssh-copy-id tool or manually add the public key to ~/.ssh/authorized_keys for both your git and apps users. (If you don't need to execute any additional commands after pushing your latest commits to the remote, feel free to skip the apps user in this step.)

Next you'll need to encrypt the private key via the Travis CLI. Note that a Linux/OSX environment is necessary for this function to work properly, so some sort of emulation layer is necessary for Windows. Either way, install the Travis CLI. Once you've done that, run travis encrypt-file id_rsa (your filename may differ). I would recommend running this command inside your repository and using the --add flag to automatically add the correct commands to .travis.yml. Check this id_rsa.enc file into Git (I recommend putting under a .travis directory), but do not add the unencrypted id_rsa file; however, you should add the id_rsa.pub file just in case. This does not need to be encrypted.

Remote Git repository

Assuming you already have your Git repository cloned onto the remote server, the next step is to configure it to allow pushes. Run git config --local receive.denyCurrentBranch updateInstead to allow Git to accept pushes to a remote with a clean working tree. Generate 4096 ssh key online. Once you've done that, make sure that the user and the group can access and modify the repository folder's contents (chown apps:deploy -R my-repo; chmod g+rw -R my-repo). You are now ready to start configuring Travis!

Configuring Travis

The main configuration file that Travis uses is .travis.yml. The commands and configs you'll want to change depend on your language, so just take a look at the official Travis guide for that. The only things you'll need to worry about are the before_install and after_success hooks. If you encrypted the SSH private key correctly, you should have a command in the before_install section containing some OpenSSL stuff. If you don't, try re-encrypting the file. The after_success hook should contain the scripts you want to execute after your tests succeed. I named my script deploy.sh and put it in the .travis folder that I previously created during the encryption step.

Once you're done with the deploy script, push it to your repository and enable Travis integration for it. The next step is to add environment variables to Travis to keep your IP, SSH port, and deploy directory secret. In the Travis menu, select your repository, click 'More options', and click 'Settings'. Scroll down until you see the list of environment variables. There should be some already there that were added by the Travis CLI in the form encrypted_[hex string]_iv/key. Leave those alone. Add IP, PORT, and DEPLOY_DIR variables with their corresponding values. For full security, do not display these values in the build log. Once you've finished that, you're done!
