# This will install Docker Engine and Docker Compose v2 on your Ubuntu VM

## **Run the following command to uninstall all conflicting packages:**

```sudo apt remove $(dpkg --get-selections docker.io docker-compose docker-compose-v2 docker-doc podman-docker containerd runc | cut -f1)```

---

## **Set up Docker's apt repository.**

```
# Add Docker's official GPG key:
sudo apt update
sudo apt install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
sudo tee /etc/apt/sources.list.d/docker.sources <<EOF
Types: deb
URIs: https://download.docker.com/linux/ubuntu
Suites: $(. /etc/os-release && echo "${UBUNTU_CODENAME:-$VERSION_CODENAME}")
Components: stable
Architectures: $(dpkg --print-architecture)
Signed-By: /etc/apt/keyrings/docker.asc
EOF

sudo apt update
```

---

## **Install the Docker packages.**

```sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin```

---

### After installation, verify that Docker is running:

```sudo systemctl status docker```

### If Docker is not running, start it manually:

```sudo systemctl start docker```

---

## **Verify that the installation is successful by running the ```hello-world``` image:**

```sudo docker run hello-world```

---

## **One-liner to run the entire package**

```
