+1) Update OS and install prerequisites
+# update
+apt update && apt upgrade -y
+# ensure basic tools exist
+apt install -y curl jq apt-transport-https ca-certificates gnupg lsb-release
+
+
+2) Install Docker (quick & reliable method)
+# run Docker install script (works for most Ubuntu versions)
+curl -fsSL https://get.docker.com -o get-docker.sh
+sh get-docker.sh
+# enable and start docker
+systemctl enable --now docker
+
+# add current user to docker group if not root (optional)
+# (you're root so this isn't required now)
+# usermod -aG docker <youruser>
+
+3) Create a persistent data directory for Redpanda
+mkdir -p /var/lib/redpanda/data
+chown root:root /var/lib/redpanda/data
+chmod 700 /var/lib/redpanda/data
+
+4) Pull the official Redpanda Docker image
+docker pull docker.redpanda.com/redpandadata/redpanda:latest
+
+
+5) Get the VM public IP (used for advertised address)
+PUBLIC_IP=$(curl -s http://169.254.169.254/metadata/v1/interfaces/public/0/ipv4/address || hostname -I | awk '{print $1}')
+echo "Public IP: $PUBLIC_IP"
+
+6)Run Redpanda container (single-node POC)
+docker run -d --name redpanda \
+  --restart unless-stopped \
+  -p 9092:9092 \
+  -p 9644:9644 \
+  -p 8081:8081 \
+  -v /var/lib/redpanda/data:/var/lib/redpanda/data \
+  docker.redpanda.com/redpandadata/redpanda:v24.1.7 \
+  redpanda start \
+    --overprovisioned \
+    --smp 1 \
+    --check=false \
+    --kafka-addr PLAINTEXT://0.0.0.0:9092 \
+    --advertise-kafka-addr PLAINTEXT://${PUBLIC_IP}:9092
+
+7) Verify container and logs
+# list container
+docker ps --filter name=redpanda
+# watch log
+docker logs -f redpanda
+
+8) Test quickly (create topic + produce + consume)
+You can run rpk inside the running container to create topics and test:
+
+# create a topic
+docker exec -it redpanda rpk topic create test-topic
+
+# produce a message (type text, then Ctrl+D)
+docker exec -it redpanda rpk topic produce test-topic
+hello from redpanda
+# Ctrl+D
+
+# consume messages (press Ctrl+C to exit)
+docker exec -it redpanda rpk topic consume test-topic --brokers ${PUBLIC_IP}:9092
+
+
+9) run the ui
+docker run -d   --name redpanda-console   -p 8082:8080   -e KAFKA_BROKERS=${PUBLIC_IP}:9092   docker.redpanda.com/redpandadata/console:latest
