As a dev, I need to create function to generate Github CI/CD workflow

Implement Github CI/CD Workflow for Naas space

This issue aims to implement a Github CI/CD workflow generator for a Naas space. The workflow will be triggered when a new release/tag is created and managed by the semantic-release process.

Specifications

• Implement the function naas.space.generate_ci(space_name, registry_name, dockerfile_path, docker_context, ci_type) in Python.
• The CI/CD workflow should:
  1. Checkout the code
  2. Use a CI/CD variable/secret to authenticate on auth.naas.ai
  3. Ask for temporary credentials on space.naas.ai/registry/registry_name/credentials to be able to login and push the built container
  4. Docker login against the container registry
  5. Get the url of the space by calling space.naas.ai/registry/registry_name
  6. Build the container
  7. Tag the container
  8. Push the container
  9. Update the space version by calling PUT space.naas.ai/space/space_name

Creating a Github CI/CD workflow that will be triggered on new tags

To create a Github CI/CD workflow that is triggered on new tags, include the following in your workflow YAML file:

on:
  push:
    tags:
      - '*'

This will ensure the workflow is only triggered on new tags, and not on every push to the repository.

Using Jinja2 with Python to template a file

Jinja2 is a popular templating engine for Python. To use Jinja2 to template a file, follow these steps:

1. Install Jinja2: pip install jinja2
2. Create a template file (e.g., template.j2) with placeholders for variable values, using the double curly brace syntax: {{ variable_name }}
3. In your Python script, import Jinja2 and load the template file:

from jinja2 import Environment, FileSystemLoader

env = Environment(loader=FileSystemLoader('.'))
template = env.get_template('template.j2')

4. Render the template with the desired variable values:

rendered_template = template.render(variable_name=value)

5. Save the rendered template to a new file:

with open('output_file.yaml', 'w') as output_file:
    output_file.write(rendered_template)

Replace output_file.yaml with the desired output file name, and ensure the variable names in the template match the variables passed to the render() function.
