How to remove apt command from a prebuilt docker image

 If you want to remove the `apt` command from a prebuilt Docker image, you can create a new Docker image based on the existing one and remove `apt` and its related packages during the image build process. Here's how you can do it:


1. **Dockerfile**:

   Create a new `Dockerfile` to build a new image. In this Dockerfile, you will start with the base image you want to modify and remove the `apt` command and related packages. For example:


   ```Dockerfile

   # Use the base image you want to modify

   FROM base_image:tag


   # Remove the apt package manager

   RUN apt-get remove --purge -y apt && apt-get autoremove -y && apt-get clean

   ```


   Replace `base_image:tag` with the actual name and tag of the base image you want to modify.


2. **Build the New Image**:

   Build the new Docker image using the Dockerfile you created. Make sure the Dockerfile is in the same directory where you run the build command.


   ```bash

   docker build -t modified_image:tag .

   ```


3. **Run the New Image**:

   You can now run containers from the new image without the `apt` command:


   ```bash

   docker run -d modified_image:tag

   ```


Keep in mind that this approach creates a new Docker image that doesn't include the `apt` command, but it does not modify the existing image. This way, you can run containers based on the new image that do not have access to `apt`.

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
