Docker is the most useful web development tool you’re not using. This course is your guide for building all kinds of web applications with Docker.

You will be introduced to Docker basics including its architecture, images, and containers. Then you'll run various databases and view them via CLI or Adminer. Next, you will learn how easy it is to use WordPress with Docker. After that is the Node.js app and its live editing and debugging with Chrome's devTools. Finally, you will make your own project to practice your Docker knowledge.

By the end of the course, you will be able to confidently use Docker in any of your further projects.

Docker for Web Developers

Docker can be installed on [Linux](#install-docker-on-linux), [mac OS](#install-docker-on-macos), or [Windows 10](#install-docker-on-windows). Requirements and installation instructions can be found on the [Docker Docs](https://docs.docker.com/engine/install/) help pages.



## Install Docker on Linux

Docker is often available in official Linux repositories, although these usually offer older editions. The latest edition is supported on recent 64-bit editions of popular Linux distros:

* [Ubuntu (and derivatives such as Mint)](https://docs.docker.com/install/linux/docker-ce/ubuntu/)
* [CentOS](https://docs.docker.com/install/linux/docker-ce/centos/)
* [Debian](https://docs.docker.com/install/linux/docker-ce/debian/)
* [Fedora](https://docs.docker.com/install/linux/docker-ce/fedora/)

[Static binaries](https://docs.docker.com/install/linux/docker-ce/binaries/) are available for other distros, although Googling "install Docker on [your OS]" may provide easier instructions, e.g., "install Docker on a Raspberry Pi".

Follow the Docker documentation for your distro. For example, [Docker for Ubuntu](https://docs.docker.com/engine/install/ubuntu/) is installed with the following commands:

```sh
sudo apt-get remove docker docker-engine docker.io containerd runc
```
```sh
sudo apt-get update
```
```sh
sudo apt-get install \
  apt-transport-https \
  ca-certificates \
  curl \
  gnupg-agent \
  software-properties-common
```
```sh
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | \
  sudo apt-key add -
```
```sh
sudo apt-key fingerprint 0EBFCD88
```
```sh
sudo add-apt-repository \
  "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) \
  stable"
```
```sh
sudo apt-get update
```
```sh
sudo apt-get install docker-ce docker-ce-cli containerd.io
```

> [Convenience scripts are also available](https://docs.docker.com/engine/install/ubuntu/#install-using-the-convenience-script) to run these commands for you, but the Docker documentation warns that they are a security risk and should not be used in production environments:
>
> ```sh
> curl -fsSL https://get.docker.com -o get-docker.sh
> sudo sh get-docker.sh
> ```

To run Docker commands as a non-root user (without `sudo`), create and add yourself to a `docker` group:

```bash
sudo groupadd docker
sudo usermod -aG docker $USER
```

Then reboot to apply all changes.


### Install Docker Compose on Linux

Docker Compose is [installed separately](https://docs.docker.com/compose/install/) using the command:

```bash
sudo curl \
  -L "https://github.com/docker/compose/releases/download/<VERSION>/ \
      docker-compose-$(uname -s)-$(uname -m)" \
  -o /usr/local/bin/docker-compose
```
```sh
sudo chmod +x /usr/local/bin/docker-compose
```

where `<VERSION>` is the [latest release number](https://github.com/docker/compose/releases), e.g., `1.27.4`.
