-\maketitle
-
-\section*{Instructions}
-
-\textbf{Prerequisites:} Docker, Kubernetes, BusyBox, and OpenSSL installed, along with a working directory containing a Dockerfile.
-
-\begin{enumerate}
-    \item \textbf{Run a Local Docker Registry (without authentication):}
-    \begin{lstlisting}
-docker run -d -p 5000:5000 --name registry registry:2
-    \end{lstlisting}
-    This command starts a registry container on \texttt{localhost:5000}.
-
-    \item \textbf{Optional: Enable Authentication for the Local Registry}
-
-    If you want to secure your local registry with a username and password, follow these steps:
-    
-    \begin{enumerate}
-        \item \textbf{Create a User and Password Hash with BusyBox:}
-        Generate a hashed password for `passpass` and store it in the `htpasswd` file:
-        \begin{lstlisting}
-mkdir -p /home/user/auth
-echo "user:$(busybox mkpasswd -m sha256 -S $(openssl rand -hex 6) passpass)" > /home/user/auth/htpasswd
-        \end{lstlisting}
-        This command generates a hashed password `passpass` for the username `user`.
-
-        \item \textbf{Run the Registry with Authentication:}
-        Restart the registry container to require authentication.
-        \begin{lstlisting}
-docker stop registry
-docker rm registry
-docker run -d -p 5000:5000 --name registry \
-  -v /home/user/auth:/auth \
-  -e "REGISTRY_AUTH=htpasswd" \
-  -e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" \
-  -e "REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd" \
-  registry:2
-        \end{lstlisting}
-    \end{enumerate}
-    
-    \item \textbf{Build and Push Docker Image to Local Registry:}
-    \begin{lstlisting}
-docker build -f Dockerfile -t localhost:5000/my-app:latest ..
-docker push localhost:5000/my-app:latest
-    \end{lstlisting}
-
-    \item \textbf{Configure Kubernetes to Use the Local Registry (if using authentication):}
-    Create a Kubernetes secret with credentials to access the registry:
-    \begin{lstlisting}
-kubectl create secret docker-registry regcred \
-  --docker-server=localhost:5000 \
-  --docker-username=user \
-  --docker-password=passpass \
-  --docker-email=user@example.com
-    \end{lstlisting}
-    This secret can be referenced by Kubernetes to pull the image from the secured local registry.
-
-    \item \textbf{Deploy a Pod Using the Image from the Local Registry:}
-    \begin{lstlisting}
-kubectl run my-app --image=localhost:5000/my-app:latest --image-pull-policy=IfNotPresent
-    \end{lstlisting}
-\end{enumerate}
-
-\section{Adding a Docker Image to Minikube and Exposing It}
-
-\subsection{Load Docker Image into Minikube}
-
-1. \textbf{Build and Load Docker Image Directly into Minikube:}
-   If the image is built locally, you can load it directly into Minikube:
-
-   \begin{lstlisting}
-   minikube image load my-app:latest
-   \end{lstlisting}
-
-   Alternatively, if you are using a local registry, ensure Minikube can access it by setting the registry address in the image tag.
-
-\subsection{Create and Run a Pod with the Loaded Image}
-
-1. \textbf{Create a Deployment in Minikube:}
-   Create a Kubernetes Deployment to manage the pod using the loaded image:
-
-   \begin{lstlisting}
-   kubectl create deployment my-app --image=my-app:latest
-   \end{lstlisting}
-
-2. \textbf{Expose the Deployment as a Service:}
-   Expose the Deployment to make the application accessible on an external port:
-
-   \begin{lstlisting}
-   kubectl expose deployment my-app --type=NodePort --port=80 --target-port=8080
-   \end{lstlisting}
-
-   In this example, Kubernetes maps port 80 of the service to port 8080 of the container. Modify `target-port` if your application uses a different port.
-
-\subsection{Access the Application Externally}
-
-1. \textbf{Retrieve the Minikube Service URL:}
-   Minikube provides a command to get the external URL for accessing services. Run the following command to get the URL:
-
-   \begin{lstlisting}
-   minikube service my-app --url
-   \end{lstlisting}
-
-   This command will output a URL that you can use to access the service from outside of Minikube.
