In this guide, we’ll link a private Azure DevOps repository to a Valohai project using a deploy key.
- A private Azure DevOps repository
- A Valohai project
- A tool that generates SSH keys. This guide uses
- You’re familiar with Git for Data Science: What every data scientist should know about Git
Generate an SSH key pair
ssh-keygen to create a new SSH key pair.
ssh-keygen -t rsa -b 4096 -f my-project-deploy-key
This will generate two files:
my-project-deploy-key.pubis the public key you add to Azure DevOps.
my-project-deploy-keyis the private key you add to Valohai.
Don’t include the keys in your version control
You should not include these keys in the version control. Anybody that gains access to the
my-project-deploy-key file contents will have read access to your repository, so use appropriate caution.
Add the public key to Azure DevOps
my-project-deploy-key.pub file we generated in the last section, and it should contain one line that starts with
ssh-rsa AAAA.... This line is the public key that we’ll be adding to Azure DevOps.
Now go to your Azure DevOps repository and navigate to the add deploy key page by clicking on User settings > SSH Public Keys
Add the private key to Valohai
Go to app.valohai.com and navigate to the repository settings in your Valohai Project through Settings > Repository.
To make sure you get the correct repository URL, open Azure DevOps in another tab. On Azure DevOps, navigate to your project > Repository page and under Clone to your computer
Make sure you Clone with SSH. By default, the HTTPS is selected so make sure you click the SSH button to get the right URL.
Then copy the text field with
Next, paste the SSH URL
email@example.com:<owner>/<repository>.git) into the URL field.
On your local machine, find the
my-project-deploy-key file (without the
.pub extension) we generated before. It should contain multiple lines starting with
-----BEGIN RSA PRIVATE KEY----- or something similar. The contents of this file are the private key we’ll be adding to Valohai. Copy and paste the contents of
my-project-deploy-key into the SSH private key field.
After you click Save, Valohai links the Azure DevOps repository to the project and automatically fetches your code.
After you add new commits to your Azure DevOps repository, remember to press the Fetch repository to update the code in Valohai.
