How to setup an OpenRC service to run at "login" level?

 To set up an OpenRC service to run at the "login" level in OpenRC-init based Linux distributions, you need to create a service script and define the runlevel at which it should start. Here are the steps:


1. **Create the Service Script**:

   Create a script for your service in the `/etc/init.d/` directory. You can name it anything you like. For example, let's call it "my_service."


   ```bash

   sudo nano /etc/init.d/my_service

   ```


   Inside this script, you should define the start and stop actions for your service. Here's a simple example:


   ```bash

   #!/sbin/openrc-run


   depend() {

      need net

   }


   start() {

      ebegin "Starting my_service"

      # Your start commands here

      eend $?

   }


   stop() {

      ebegin "Stopping my_service"

      # Your stop commands here

      eend $?

   }

   ```


   Make sure to replace `# Your start commands here` and `# Your stop commands here` with the actual commands for starting and stopping your service.


2. **Set the Runlevel**:

   OpenRC uses runlevels to determine when a service should start. The "login" runlevel corresponds to runlevel `default` on many systems. To set your service to run at the "login" level, you can create a symlink in the appropriate runlevel directory:


   ```bash

   sudo ln -s /etc/init.d/my_service /etc/runlevels/default/my_service

   ```


3. **Start the Service**:

   To start the service immediately, run:


   ```bash

   sudo rc-service my_service start

   ```


4. **Enable the Service on Boot**:

   To have the service start automatically at boot, you can enable it:


   ```bash

   sudo rc-update add my_service default

   ```


   Now, your "my_service" should start at the "login" runlevel.


Please note that the exact steps may vary depending on your specific OpenRC-based distribution. Be sure to consult the documentation or specific guides for your distribution if you encounter any issues.

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
