Simplify your Divio application deployment with a Python script#

The ci-cd.py script enables you to deploy a Divio application environment with customizable options. You can specify an environment slug, a branch, and other parameters to facilitate the deployment process. The script automates the creation of environments, branch handling, and triggering of deployments.

Requirements#

Before running the script, ensure you have the following requirements in place:

  • Python 3.x: The script requires Python 3.x. If it’s not installed, download it from the official Python website.

  • GitPython Library: The script uses the GitPython library to interact with Git repositories. Install it using the following command in your terminal:

pip install GitPython

  • requests library: The script also uses the requests library to make HTTP requests to the Divio API. Install the library by running the following command in your terminal:

pip install requests

Running the Script#

  • Download the Script: Save the ci-cd.py Python script to a directory on your system.

  • Navigate to Script Directory: Open a terminal and navigate to the directory where you saved the ci-cd.py script.

  • Execute the Script: Run the script using the following command, providing the required command-line arguments:

python ci-cd.py APP_UUID API_TOKEN [--env_slug ENV_SLUG] [--branch BRANCH] [--repository_path
REPO_PATH] [--source_env_slug SOURCE_ENV_SLUG]

  • Replace placeholders:

    Mandatory arguments:

    • APP_UUID: Application UUID. Extract the UUID from the Divio application dashboard URL, after the /app/ part. For example, if the application URL is https://control.divio.com/o/m5x6hm4etbgcblfgxkya4kzeva/app/xvtm6s5vqveohktyvdsafrupqa/, the application UUID would be “xvtm6s5vqveohktyvdsafrupqa”`.

    • API_TOKEN: Your Divio API token.

    Optional arguments:

    • –env_slug ENV_SLUG: Environment slug (default: "test").

    • –branch BRANCH: Branch name.

    • –repository_path REPO_PATH: Local repository path.

    • –source_env_slug SOURCE_ENV_SLUG: Source environment slug for copying (default: "live").

Upon execution, the script dynamically manages the deployment process according to the provided arguments. It displays real-time deployment status messages in the terminal, offering clear insights into the success or failure of the deployment process.

Script behavior based on argument combinations#

Deploying default environment, the "test":#

  • If no additional arguments are provided, the script will deploy the default environment, which is the "test" environment.

Deploying environment with ENV_SLUG:#

  • If the ENV_SLUG argument is provided:

    • If an environment with the given ENV_SLUG exists, the script will deploy the specified environment.

    • If an environment with the given ENV_SLUG does not exist, the script will create a new environment with the provided ENV_SLUG by copying from the default source environment, which is the "live" environment, and then deploy the new environment.

Deploying environment with SOURCE_ENV_SLUG:#

  • If the SOURCE_ENV_SLUG argument is also provided along with the ENV_SLUG argument:

    • The script will create a new environment with the specified ENV_SLUG by copying from the given source environment (specified by SOURCE_ENV_SLUG) and deploy the new environment.

    • Note that an environment with the given SOURCE_ENV_SLUG must exist for this operation. Should such an environment not exist, the script will terminate and display an error message.

Deploying Environment with BRANCH:#

  • If the BRANCH argument is also provided: * If no ENV_SLUG is provided or if the ENV_SLUG already exists, the script will report an error message: “Environment exists. Please do not provide a branch argument.”

    • If a branch with the provided BRANCH name does not exist, the script will:

      • Use the provided REPO_PATH to create a branch and push it to the remote repository.

      • If REPO_PATH is not provided, the script will exit with an error message: “Error: repository_path must be provided when creating a new branch.”

    • If a new environment is created by copying:

      • The new environment’s branch will be updated with the provided BRANCH. The new environment will then be deployed.

By following these steps, you can effectively utilize the ci-cd script to streamline the process of deploying Divio application environments with customized settings.
