Step 1: Update the System

It's important to ensure your system is up-to-date. Run the following command to update and upgrade your packages:

Portainer requires Docker to be installed. If you don’t have Docker installed, follow these steps:

Add Docker's GPG key:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

Add the Docker repository:

echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null

Install Docker:

apt update
apt install docker-ce docker-ce-cli containerd.io -y

Start and enable Docker:

systemctl start docker
systemctl enable docker

Check Docker status:

systemctl status docker
