How to export proxy in Redhat Linux 7 using the current login credentials?

 In Red Hat Linux 7, you can set up a proxy using environment variables, specifically `http_proxy`, `https_proxy`, `ftp_proxy`, and `no_proxy`. To use your current login credentials for proxy authentication, you'll need to include your username and password in the proxy URL. Here's how you can do it:


1. Open a terminal and run the following commands:


   ```bash

   export http_proxy="http://username:password@proxy_server:proxy_port"

   export https_proxy="https://username:password@proxy_server:proxy_port"

   export ftp_proxy="ftp://username:password@proxy_server:proxy_port"

   ```


   - Replace `username` with your proxy username.

   - Replace `password` with your proxy password.

   - Replace `proxy_server` with the address of your proxy server.

   - Replace `proxy_port` with the port number used by your proxy server.


2. If your proxy server doesn't require a username and password, you can omit them. For example:


   ```bash

   export http_proxy="http://proxy_server:proxy_port"

   export https_proxy="https://proxy_server:proxy_port"

   export ftp_proxy="ftp://proxy_server:proxy_port"

   ```


3. To ensure that you don't need to enter your credentials every time you open a new terminal session, you can add these export commands to your shell's profile configuration file. For Bash, this file is typically `~/.bashrc`. For example:


   ```bash

   echo 'export http_proxy="http://username:password@proxy_server:proxy_port"' >> ~/.bashrc

   echo 'export https_proxy="https://username:password@proxy_server:proxy_port"' >> ~/.bashrc

   echo 'export ftp_proxy="ftp://username:password@proxy_server:proxy_port"' >> ~/.bashrc

   ```


4. Make sure to replace `~/.bashrc` with the appropriate configuration file if you're using a different shell, such as `~/.zshrc` for Zsh.


5. After modifying your profile configuration file, reload it to apply the changes without logging out or rebooting:


   ```bash

   source ~/.bashrc

   ```


Remember that including your username and password in plain text within the proxy URL is not recommended from a security perspective. If possible, use a more secure method for proxy authentication, such as NTLM or Kerberos, or consider using a dedicated proxy authentication tool or utility that can securely manage your credentials.

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
