Airflow variable encryption not showing

 If Airflow variable encryption is not working as expected and the encrypted values are not displayed properly, you might need to troubleshoot the issue. Airflow provides a feature to encrypt sensitive variable values stored in the metadata database. Here are steps to diagnose and resolve the problem:


1. **Check Airflow Version**: Ensure you are using a version of Airflow that supports variable encryption. Variable encryption was introduced in Airflow 1.10.9, so if you are using an older version, consider upgrading.


2. **Encryption Algorithm**: Verify that the encryption algorithm is properly configured in your Airflow installation. Airflow uses the `Fernet` symmetric key encryption algorithm by default. Ensure that the key used for encryption and decryption is the same.


3. **Key Configuration**: Double-check that the `fernet_key` is correctly set in your `airflow.cfg` configuration file. The key should be stored in a secure manner.


   ```ini

   [secrets]

   fernet_key = YourFernetKeyHere

   ```


4. **Variable Encryption**: When setting encrypted variables using the Airflow CLI or web interface, ensure that you specify the `--encrypt` flag to encrypt the value. For example:


   ```bash

   airflow variables -s my_variable "my_secret_value" --encrypt

   ```


5. **Viewing Encrypted Values**: Encrypted variable values are shown with an "Encrypted" tag in the Airflow web interface and CLI. You won't see the actual decrypted value, and this is expected behavior. To retrieve the decrypted value in your DAG code, you can use `Variable.get()`:


   ```python

   from airflow.models import Variable


   my_variable_value = Variable.get("my_variable", deserialize_json=False)

   ```


6. **Permissions**: Ensure that the user or role running the Airflow web server and scheduler has the necessary permissions to decrypt the variable values. Insufficient permissions can prevent decryption.


7. **Logging**: Review the Airflow logs for any error messages related to variable encryption or decryption. Log output might provide clues about what's going wrong.


8. **Database**: If you've recently migrated to a new Airflow database or environment, make sure that the database is correctly set up to handle encrypted variables. Variable encryption relies on database storage.


9. **Re-Encryption**: If you suspect an issue with the encryption keys or if keys have been changed, you might need to re-encrypt your variables with the current keys. Use the `airflow variables --encrypt` command to update the variables.


10. **Testing**: If you're still experiencing issues, consider testing variable encryption in a fresh Airflow installation to ensure that the problem is not specific to your environment.


If none of these steps resolves the issue, you might want to check the Airflow mailing list or forum for additional help or report the problem as a possible bug in the Airflow project's issue tracker.

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
