Quick Setup of SSH Keys for Github And Azure

Github SSH Setup:

This sccript is in two versions:

Linux: github-ssh-setup.sh
Windows+Git Bash: github-ssh-setup_OS_WINDOWS.sh

1. Clone this project

git clone https://github.com/martinandersen3d/github-ssh-key-setup.git

2. Run the script

cd github-ssh-key-setup/
./github-ssh-setup.sh

Step 3, has two options:

3A. Add Keys on your Profile (Computer will have access to ALL your repositories):

Use this option if your are settings up your developer computer.

https://github.com/settings/keys

3B. Add Keys on a git repository (Computer will have access ONLY on the repositories, where you add the key):

Use this option if your have a server, that needs access to ONE or more private/public repositories.

Go to the repository you want the server to access.
Go into repository > Settings
Deploy keys
Add Deploy key

Demonstration

Azure Devops SSH Setup:

Todo:

Currently it overwrites the file in c:\users\$USER\.ssh\config, if you have any data there, make a backup before you run the script
Replace all github descriptions with Azure Devops descriptions

Demonstration - Azure

Note: For some stupid reason Microsoft needs TWO domains to make the SSH work for Azure, and not one domain like everyone else.

Example of config file: C:\Users\MyUsername.ssh\config

Host ssh.dev.azure.com
   PubkeyAcceptedKeyTypes=ssh-rsa
   HostName ssh.dev.azure.com
   IdentityFile C:\Users\MyUsername\.ssh\azure_rsa
   IdentitiesOnly yes
   AddKeysToAgent yes
   PasswordAuthentication=no
   User git

Host vs-ssh.visualstudio.com
  IdentityFile C:\Users\MyUsername\.ssh\azure_rsa
  IdentitiesOnly yes

Important Note on using Multiple Deploy keys in eg. github

You should have a config file in: Windows:

C:\Users\<username>\.ssh\config

Linux:

~/.ssh/config

If you have mulitple repos from github you want to add Deploy keys to, you might need to edit the config file, like this: Windows example:

host github_superman
 HostName github.com
 IdentityFile C:/Users/username/.ssh/github_superman_id_rsa
 User git

host github_catwoman
 HostName github.com
 IdentityFile C:/Users/username/.ssh/github_catwoman_id_rsa
 User git

And your git clone, command will need to be changed:

git clone git@github_superman:githubusername/repo.git
git clone git@github_catwoman:githubusername/repo.git
