In this guide, we will connect a private GitHub repository to a Valohai project using a deploy key.
- A private GitHub 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 GitHub.
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 GitHub
my-project-deploy-key.pub the 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 will be adding to GitHub.
Now go to your GitHub repository and navigate to the add deploy key to page through Settings > Deploy keys > Add deploy key.
Add new deploy key
- Copy and paste the contents of
my-project-deploy-key.pubinto the Key field.
- Give the deploy key an identifying Title such as Valohai.
- Valohai doesn’t require write access, make sure that is off.
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 GitHub in another tab. On Github, navigate to Code page and press Clone or download.
Make sure you have Clone with SSH active on the popup window. If it reads Clone with HTTPS, click the Use SSH button next to the text.
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 GitHub repository to the project and automatically fetches your code.
After you add new commits to your GitHub repository, remember to press the Fetch repository to update the code in Valohai.
