Portainer update

Here's a short bash script to update Portainer on Debian (assuming it's running in Docker, the most common setup):

#!/bin/bash

# Update Portainer container
set -e

echo "Stopping Portainer container..."
docker stop portainer

echo "Removing old container..."
docker rm portainer

echo "Pulling latest Portainer image..."
docker pull portainer/portainer-ce:latest

echo "Starting Portainer container..."
docker run -d \
  --name portainer \
  --restart always \
  -p 8000:8000 \
  -p 9000:9000 \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v portainer_data:/data \
  portainer/portainer-ce:latest

echo "Portainer updated successfully!"
docker ps | grep portainer

Or if you prefer a simpler approach using docker compose:

#!/bin/bash

cd /path/to/docker-compose/directory
docker compose pull portainer
docker compose up -d portainer

echo "Portainer updated!"

If Portainer is installed standalone (less common):

#!/bin/bash

PORTAINER_PATH="/opt/portainer"

systemctl stop portainer
cd $PORTAINER_PATH
wget https://github.com/portainer/portainer/releases/latest/download/portainer
chmod +x portainer
systemctl start portainer

echo "Portainer updated!"

Which one do you use? I can refine the script based on your setup. Also, let me know if you need:

• Automatic cleanup of old images
• Backup before update
• Health check validation
