Deployment Overview of Minikube on Server¶

Prerequisites and Basic Requirements¶

To ensure a successful deployment, the server must meet the following requirements:

Operating System: Ubuntu (specifically required for the automated installation tasks).
Privileges: Root or sudo access is required to install packages and manage system binaries.
Dependencies:
Python 3 with pip installed.
Docker engine must be present on the host to serve as the Minikube driver.

Application installation process¶

The installation of Minikube and its associated Kubernetes management tools is performed through a series of system configuration steps:

System Package Installation: The installer ensures that python3-pip is installed and uses it to install the docker Python library for programmatic interaction with the Docker engine.
Minikube Binary Deployment:
The latest Minikube binary for Linux (amd64) is downloaded from Google Cloud Storage.
The binary is moved to /usr/local/bin/minikube.
Execution permissions are granted via chmod +x.
Kubernetes CLI Installation:
The latest stable version of the Kubernetes release URL is retrieved.
The kubectl binary is downloaded from the official Kubernetes repository and placed in /usr/local/bin/kubectl.
Permissions are set to 0755 (executable).
Environment Configuration: The /usr/local/bin directory is appended to the system PATH within the user's .bashrc file to ensure commands are available in all new shell sessions.
Minikube Initialization: Minikube is started using the Docker driver with the --force flag:
```
minikube start --driver=docker --force
```

Custom Scripts and Additional Setup¶

The deployment process includes several lifecycle management actions:

System Notification: The installation process triggers external notifications at various stages (start, progress updates, and completion) to monitor the deployment status.
Environment Path Update: A script modifies the .bashrc file to ensure that newly installed binaries in /usr/local/bin are immediately accessible to the user environment.

Application Update Instructions¶

To update the Minikube installation:

Download and replace the existing binary in /usr/local/bin/minikube with the latest version from the official repository.
Apply execution permissions: chmod +x /usr/local/bin/minikube.

Restart the Minikube instance to apply changes:

minikube stop
minikube start --driver=docker

Available ports for connection¶

The application utilizes Docker as a driver; therefore, connectivity depends on the specific Kubernetes services deployed within the cluster. Standard management access is provided via kubectl once the environment is initialized.
