# Docker

## --mount option requires BuildKit. Refer to https://docs.docker.com/go/buildkit/ to learn how to build images with BuildKit enabled

Set Up the Docker Repository
Install required dependencies:
```bash
sudo apt-get install -y ca-certificates curl gnupg lsb-release
```

Add Docker’s official GPG key:

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

Add Docker’s repository:

```bash
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
```

Update the package index again:

```bash
sudo apt-get update
```

Install Docker Components
Now install Docker and its related components:

```bash
sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-
```

Verify Docker Installation
Check if Docker is installed correctly:

```bash
docker --version
docker buildx version
```
