Fix: fpm-php + nginx + POST data

 When using Nginx with PHP-FPM and you need to handle POST data, you typically need to configure your Nginx server and PHP-FPM to work together to process incoming POST requests. Here's a basic setup to handle POST data with Nginx and PHP-FPM:


1. **Install Nginx and PHP-FPM**:

   If you haven't already, you'll need to install Nginx and PHP-FPM. You can use your system's package manager (e.g., apt, yum) to install them.


2. **Nginx Configuration**:

   Edit your Nginx configuration file, typically located at `/etc/nginx/nginx.conf` or `/etc/nginx/sites-available/default`. Make sure you have a server block configured to handle PHP requests. Here's a simplified example:


   ```nginx

   server {

       listen 80;

       server_name yourdomain.com;


       location / {

           index index.php;

           try_files $uri $uri/ /index.php?$query_string;

       }


       location ~ \.php$ {

           include fastcgi_params;

           fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;

           fastcgi_index index.php;

           fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

       }

   }

   ```


   Ensure that `fastcgi_pass` points to the correct PHP-FPM socket file, which may vary depending on your PHP-FPM configuration.


3. **PHP Configuration**:

   You may need to adjust your PHP-FPM configuration to allow the handling of POST data. Open your PHP-FPM configuration file, usually located at `/etc/php-fpm.d/www.conf`, and ensure the following settings are in place:


   ```ini

   request_terminate_timeout = 300

   request_slowlog_timeout = 0

   php_flag[display_errors] = off

   ```


   The `request_terminate_timeout` setting controls the maximum time a PHP script is allowed to run. Adjust it as needed. The `php_flag[display_errors]` setting is optional but recommended for security to disable error display in the response.


4. **Restart Services**:

   After making changes to your Nginx and PHP-FPM configurations, restart both services:


   ```bash

   sudo service nginx restart

   sudo service php-fpm restart

   ```


5. **Handling POST Data in PHP**:

   In your PHP script, you can access POST data using the `$_POST` superglobal. For example:


   ```php

   if ($_SERVER['REQUEST_METHOD'] === 'POST') {

       $postData = $_POST;

       // Process the POST data as needed

   }

   ```


   You can access specific POST variables using `$_POST['variable_name']`.


Make sure your PHP script is handling POST data securely and according to your application's requirements.


With this setup, Nginx is configured to pass requests to PHP-FPM, which can then handle POST data as expected. Adjust the paths, server names, and other settings to match your specific environment and application.

bad character U+002D '-' in my helm template

 In Helm templates, the hyphen character (`-`) can sometimes be treated as a reserved character, particularly when defining values or labels. To include a hyphen character in a Helm template without issues, you can use one of the following approaches: 1. **Quoting the Hyphen:**    You can enclose the hyphen in double quotes, like this:    ```yaml    key: "-"    ```    This way, Helm will interpret the hyphen as a string rather than an operator. 2. **Using Backticks:**    If you need to use the hyphen within a Go template function or inside backticks, you can escape it with a backslash (`\`), like this:    ```yaml    value: `{{ .Values.someField | printf "%s \\-" }}`    ```    The backslash prevents Helm from interpreting the hyphen as a special character. 3. **Variable Assignment:**    Assign the value to a variable and use it. For example:    ```yaml    {{- $hyphen := "-" }}    key: {{ $hyphen }}    ```    This way, you can use the variable `$hyphen` wher

GitLab pipeline stopped working with invalid yaml error

 When your GitLab pipeline has stopped working with an "invalid YAML" error, it means there's a problem with your `.gitlab-ci.yml` file. This could be due to syntax errors, incorrect indentation, or other issues in your pipeline configuration. Here's how to troubleshoot and resolve this issue: 1. **Check for Syntax Errors**:    Carefully review your `.gitlab-ci.yml` file for any syntax errors. Common issues include missing colons, indentation problems, or mismatched quotation marks. Use a YAML linter or an online YAML validator to identify and correct syntax errors. 2. **Indentation**:    YAML relies heavily on proper indentation. Make sure that all lines within the same block have consistent indentation (typically using spaces, not tabs). Incorrect indentation can cause YAML parsing errors. 3. **Dashes and Lists**:    Ensure that you use the correct syntax for lists (arrays) in YAML by starting each item with a dash (`-`). Be consistent with your use of dashes throug

How do I add a printer in OpenSUSE which is being shared by a CUPS print server?

 To add a printer in openSUSE that is being shared by a CUPS print server, you can use the following steps: 1. **Ensure CUPS Client is Installed:**    Make sure your openSUSE system has the CUPS client tools installed. You can install them using the following command:    ```bash    sudo zypper install cups-client    ``` 2. **Discover Available Printers:**    Use the `lpinfo` command to discover available printers on your CUPS print server. Replace `cups-server-hostname` with the hostname or IP address of your CUPS server:    ```bash    lpinfo -v -h cups-server-hostname:631    ```    This command should list the printers shared by the CUPS server. 3. **Add a Printer:**    Use the `lpadmin` command to add a printer. Replace `printer-name` with the name of the printer you want to add and `printer-uri` with the URI obtained from the `lpinfo` command:    ```bash    sudo lpadmin -p printer-name -E -v printer-uri    ```    For example:    ```bash    sudo lpadmin -p MyPrinter -E -v socket://cu
