# How to set up Docker on Fedora 38 via the terminal emulator?

---

## **Docker**

Docker is a platform for developing, shipping, and running applications in containers.

Containers are lightweight, portable, and self-sufficient units that can package an application and its dependencies, including libraries and configuration files, into a single, consistent environment.

This allows developers to create, deploy, and manage applications more efficiently, regardless of the underlying infrastructure.

## Solution

---

## **Check your OS (optional)**

This step is just to ensure you have **Fedora 38 Linux installed. You can pick up one command or you can use them all.**

### /etc/os-release

```plaintext
cat /etc/os-release
```

---

### hostnamectl

```plaintext
hostnamectl
```

Output

When you run `hostnamectl` without any options, it provides detailed information about the system's hostname, operating system, kernel, and other system-related settings.

---

## lsb\_release

```plaintext
lsb_release -a
```

Output

`lsb_release` is a command-line utility commonly found in Linux distributions that adhere to the Linux Standard Base (LSB). The LSB is a standardization initiative that aims to increase compatibility between different Linux distributions by defining a common set of libraries and conventions.

---

### uname

```plaintext
uname -a
```

Output

The `uname -a` command is used to display detailed system information about the Linux operating system. It provides information about the system's kernel and other system-related details.

---

## Install dependencies

```apache
sudo dnf -y install dnf-plugins-core
```

---

## Add a YUM repo for Docker

```ruby
sudo dnf config-manager --add-repo https://download.docker.com/linux/fedora/docker-ce.repo
```

Your output should look something like the following:

```basic
[elitebughunter@192 ~]$ sudo dnf config-manager --add-repo https://download.docker.com/linux/fedora/docker-ce.repo
Adding repo from: https://download.docker.com/linux/fedora/docker-ce.repo
[elitebughunter@192 ~]$ 
```

---

### Brief explanation

`config-manager`: This is a DNF subcommand used for managing repository configurations.

`--add-repo`: This flag indicates that you want to add a new repository to the system.

[`https://download.docker.com/linux/fedora/docker-ce.repo`](https://download.docker.com/linux/fedora/docker-ce.repo): This is the URL of the Docker repository configuration file. By adding this repository, you make Docker-related packages and updates available for installation and management through DNF on your Fedora system.

---

## Check repo

```ruby
sudo dnf repolist
sudo dnf repolist | grep docker
```

Output

## Install Docker Engine, containerd, and Docker Compose

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

Output

---

## Check installation

```ruby
docker --version
which docker
docker --help
```

Your output should look something like the following:

## Check Docker status

```plaintext
sudo systemctl status docker
```

Output

The command is used to manage and control system services on Linux systems that use `systemd` as their init system is `systemctl`.

`systemd` is a system and service manager commonly used in modern Linux distributions.

---

## Start Docker

```ruby
sudo systemctl start docker
```

---

### Check the status

```plaintext
sudo systemctl status docker
```

Output:
