Github actions for Pantheon Multi-dev Environments
Setting up Github
In Github, go to the project’s Settings page. Under Security, click Secrets and then Actions.
To create a new variable, click the New repository secret button. We will need to create the following variables to the following values:
KNOWN_HOSTS
A single space is finePANTHEON_MACHINE_TOKEN
On 1Password, the Machine Token value under Pantheon Dashboard: KalaCommitBotPANTHEON_REPO
URL for the project’s pantheon repo. You can find this on the pantheon page by clicking Connection Info, then coping the url part of the Git: SSH clone URL commandPANTHEON_SITE_NAME
Machine name for the project’s pantheon site (PANTHEON_SITE_NAME.env in the site url)PANTHEON_SSH_KEY
On 1Password, under “KalaCommitBot Private SSH Key”SSH_CONFIG

In the project’s root directory, create a folder called .github, and inside that directory create a folder called workflows. Github action scripts will be .yml files inside the .github/workflows/ directory.
Create multi-dev environment
To have a github action create a multi-dev environment whenever a pull request is created in github, create a file in .github/workflows with a name like pr-open-create-multidev.yml with the following code:
name: Create Pantheon Multidev for Pull Request

git push -uf pantheon HEAD:$BRANCH_NAME

To have a github action delete a corresponding multi-dev environment whenever a pull request is closed in github, create a file in .github/workflows with a name like pr-close-delete-multidev.yml with the following code:
