Putting Oracle Linux 9.2 in the FIPS mode

 To put Oracle Linux 9.2 into FIPS (Federal Information Processing Standards) mode, you'll need to follow specific procedures to ensure that the system complies with FIPS security standards. Here's a general overview of the steps you would typically take:


1. **Check Prerequisites:**

   - Ensure that you have administrative access to the system.

   - Backup your data and configurations as enabling FIPS mode can have a significant impact on system behavior.


2. **Install FIPS-Compliant Packages:**

   - Oracle Linux includes packages specifically designed for FIPS compliance. You may need to install these packages. Use the package manager (e.g., `yum` or `dnf`) to do this.


3. **Enable FIPS Mode:**

   - Edit the `/etc/sysconfig/kernel` file to include the line: `FIPS=1`

   - Ensure the bootloader configuration also specifies FIPS mode. Edit the `/etc/default/grub` file and append `fips=1` to the `GRUB_CMDLINE_LINUX` parameter.


4. **Update the GRUB Configuration:**

   - After making changes to `/etc/default/grub`, update the GRUB configuration using the following command:

     ```bash

     sudo grub2-mkconfig -o /boot/grub2/grub.cfg

     ```


5. **Reboot the System:**

   - To activate FIPS mode, you'll need to reboot the system:

     ```bash

     sudo reboot

     ```


6. **Verify FIPS Mode:**

   - After the reboot, you can verify that the system is in FIPS mode by checking the status:

     ```bash

     cat /proc/sys/crypto/fips_enabled

     ```


   - If it returns `1`, the system is in FIPS mode.


Please note that enabling FIPS mode may have significant implications for your system's performance and compatibility with certain software applications. Ensure you understand these consequences and test the changes in a non-production environment if possible.


Additionally, the exact steps may vary depending on the specifics of your Oracle Linux version, so consult the official documentation or support resources for Oracle Linux for the most accurate and up-to-date instructions.

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
