Script Structure

The script consists of several major functions:

  • bash_aliases: Configures bash aliases and sources function definitions.
  • confiure_lvm_storage: Configures LVM storage for the Qubinode environment.
  • setup_kcli_base: Sets up KCLI (Kubernetes Cluster Lifecycle Interface) and configures images.
  • show_help: Displays help information for the script.

Full Script

Key Code Snippets

  1. bash_aliases: 
    if [ "$(pwd)" != "/root/qubinode_navigator" ]; then
 echo "Current directory is not /root/qubinode_navigator."
 echo "Changing to /root/qubinode_navigator..."
 cd /root/qubinode_navigator
fi

    This code snippet checks the current working directory and changes it if necessary. This ensures that the script runs in the correct directory.

  2. confiure_lvm_storage: 
    if [ ! -f /tmp/configure-lvm.sh ]; then
 curl -OL https://raw.githubusercontent.com/tosin2013/qubinode_navigator/main/dependancies/equinix-rocky/configure-lvm.sh
 mv configure-lvm.sh /tmp/configure-lvm.sh
 sudo chmod +x /tmp/configure-lvm.sh
fi

    This code snippet checks if the configure-lvm.sh script exists. If not, it downloads and installs the script from GitHub.

External Dependencies

The script relies on the following external dependencies:

  • Bash aliases: The script uses bash aliases to configure various components of the Qubinode ecosystem.
  • LVM storage: The script configures LVM storage for the Qubinode environment.
  • KCLI (Kubernetes Cluster Lifecycle Interface): The script sets up and configures KCLI.

Input and Output Formats

The script accepts command-line arguments, which can be used to customize its behavior. For example:

  • -h or --help: Displays help information for the script.
  • --deploy-kvmhost: Deploys a KVM host.
  • --configure-bash-aliases: Configures bash aliases.

Best Practices

When modifying or extending the script, follow these best practices:

  1. Use clear and concise variable names.
  2. Follow coding conventions and style guidelines (e.g., PEP 8 for Python).
  3. Test your changes thoroughly to ensure they do not break existing functionality.
