Ubunut 24.04

====== Installing Docker on Ubuntu 24.04 ======

To install **Docker Engine** on **Ubuntu 24.04**, the official and recommended method is to set up Docker's official ''apt'' repository. This ensures you get the latest stable version and automatic future updates.

===== Step 1: Remove Conflicting Packages =====

Before starting, remove any default or unofficial Docker packages to prevent conflicts:

<code>
sudo apt remove docker.io docker-doc docker-compose docker-compose-v2 podman-docker containerd runc
</code>

===== Step 2: Set Up the Docker Repository =====

Update your package index and install the prerequisite security certificates:

<code>
sudo apt update
sudo apt install -y ca-certificates curl gnupg
</code>

Next, add Docker's official GPG key to verify package authenticity:

<code>
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://docker.com -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc
</code>

Add the stable repository to your system's ''apt'' sources:

<code>
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://docker.com \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
</code>

===== Step 3: Install Docker Engine & Plugins =====

Update your repository index to include Docker's packages, then install Docker Engine, the CLI, and **Docker Compose V2**:

<code>
sudo apt update
sudo apt install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
</code>

===== Step 4: Verify the Installation =====

Check if the service is up and running:

<code>
sudo systemctl status docker
</code>

Run the default test container to verify it pulls and executes properly:

<code>
sudo docker run hello-world
</code>

----

===== Optional: Run Docker Without Sudo =====

By default, Docker requires root privileges. To run commands as a regular user, add yourself to the ''docker'' group:

* Create the group (usually exists already):
<code>
sudo groupadd docker
</code>
  * Add your user to the group:
<code>
sudo usermod -aG docker $USER
</code>
  * Apply the changes immediately without logging out:
<code>
newgrp docker
</code>
  * Verify by running without ''sudo'':
<code>
docker run hello-world
</code>
