Docker Installation

Remote server connection from Termius. The commands for the installation depend on the server's OS. Run this command into the Termius terminal to identify the server's OS.

cat /etc/os-release

The server OS is Ubuntu, so the from now on the commands to install Docker are meant for Ubuntu only.

1. Update the package list

sudo apt update

2. Install dependencies

sudo apt install -y apt-transport-https ca-certificates curl software-properties-common

3. Add Docker's official GPG key

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

4. Add Docker's repository

This step is important so the latest official Docker version is installed.

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

5. Update the package list again

sudo apt update

6. Start Docker

sudo systemctl start docker

7. Enable Docker

sudo systemctl enable docker

8. Verify Docker Version

docker --version

9. Verify Docker Installation

docker run hello-world

If you see "Hello from Docker!" The installation is all done!
