Install Docker on Debian 13 under PVE 9

There are mainly 2 parts of the installation:
1. Install Docker

# Update the apt package index and install packages to allow apt to use a repository over HTTPS
sudo apt update
sudo apt install ca-certificates curl gnupg

# Add Docker’s official GPG key
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg –dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

# Add the Docker repository to Apt sources
echo \
“deb [arch=”$(dpkg –print-architecture)” signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian \
“$(. /etc/os-release && echo “$VERSION_CODENAME”)” stable” | \
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

# Update the apt package index again
sudo apt update

# Install Docker Engine, containerd, and Docker Compose
sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

2. Set up a Docker container running Portainer

# Create a volume for Portainer to store its data
docker volume create portainer_data

# Deploy the Portainer Server container
docker run -d -p 8000:8000 -p 9443:9443 –name portainer –restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:lts
