Nginx Config Creator (Enterprise Grade)

This skill automates the creation of Nginx/OpenResty reverse proxy configurations. It is designed for both ease of use and safety, incorporating environment awareness and a critical safety-check mechanism.

Features

• - Environment Awareness: Simplifies commands by reading configuration from environment variables.
• Safety Check: Includes a '熔断' (fuse) mechanism. It tests the configuration before applying it and automatically rolls back if the test fails, preventing web server downtime.

Pre-requisites (Recommended)

For maximum convenience, it is recommended to set the following environment variables on the host system:

• - NGINX_CONFIG_PATH: The absolute path to the Nginx conf.d directory.
• INLINECODE2: The name of the running Nginx/OpenResty Docker container.

If these are not set, they must be provided as command-line arguments.

Core Action: scripts/create-and-reload.sh

This script performs the entire operation.

Inputs (Command-Line Arguments)

• - --service-name: (Required) The short name for the service (e.g., grafana).
• INLINECODE6: (Required) The root domain name (e.g., example.com).
• INLINECODE8: (Required) The local port the service is running on (e.g., 3000).
• INLINECODE10: (Optional) The path to Nginx's conf.d directory. Overrides the NGINX_CONFIG_PATH environment variable.
• INLINECODE13: (Optional) The name of the Nginx Docker container. Overrides the NGINX_CONTAINER_NAME environment variable.

Output

• - On Success: Prints a step-by-step log of its actions and a final success message.
• On Failure: Prints a descriptive error message to stderr and exits. If the failure occurs during the Nginx configuration test, the full error from nginx -t is displayed.

Execution Workflow

1. 1. Parse Arguments & Environment: The script gathers all necessary paths and names from command-line arguments and environment variables.
2. Generate Config: It creates the .conf file in the target directory.
3. Test Config (Safety Check): It executes nginx -t inside the specified container.
4. Decide & Act:

1. 5. Report Result: Informs the user of the final outcome.

Example Usage

Scenario 1: Environment variables are pre-set

Scenario 2: No environment variables (providing all info via arguments)

Failure Strategy

• - Missing Arguments: The script will exit with an error if required arguments/environment variables are missing.
• nginx -t Fails: The skill is designed to be safe. It will not attempt to reload a broken configuration. It will clean up after itself and show you the exact error, ensuring the live web server is never affected.
