Installing docker-mailserver on EndeavourOS Latest

Introduction

In this tutorial, we will guide you in the installation of the docker-mailserver, which is a simple, easy-to-use, and highly configurable SMTP server based on docker, and designed for advanced users.

Prerequisites

Before you start, you will need to make sure that:

You have a running EndeavourOS Latest installation.
You have root access to your EndeavourOS system.
You have Docker and Docker Compose installed.

Step 1 - Install Docker

In order to install docker, you can follow the instructions provided on the Docker website. Here are the steps:

Add the Docker GPG key to your system:

$ curl -fsSL https://download.docker.com/linux/$(. /etc/os-release; echo "$ID")/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

Add the Docker repository to the apt sources list:

$ echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/$(. /etc/os-release; echo "$ID") $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Update the package list and install Docker:

$ sudo apt update
$ sudo apt install docker-ce docker-ce-cli containerd.io

Verify that Docker is installed properly:
```
$ sudo docker run hello-world
```
If everything is working correctly, you should see a message that says "Hello from Docker!"

Step 2 - Install Docker Compose

Docker Compose is a tool that allows you to define and run multi-container Docker applications. Here are the steps to install it:

Install Docker Compose:

$ sudo curl -L "https://github.com/docker/compose/releases/download/1.29.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

Apply executable permissions:

$ sudo chmod +x /usr/local/bin/docker-compose

Verify that Docker Compose is installed:
```
$ docker-compose --version
```
If everything is working correctly, you should see a message that states the current version of Docker Compose.

Step 3 - Install docker-mailserver

Now that you have Docker and Docker Compose installed, it's time to install docker-mailserver. Here are the steps:

Clone the docker-mailserver repository:

$ git clone https://github.com/docker-mailserver/docker-mailserver.git

Navigate to the docker-mailserver directory:
```
$ cd docker-mailserver
```

Create the configuration files:

$ cp .env.sample .env

$ cp mailserver.docker-compose.sample.yml docker-compose.yml

Customize the configuration:

You can modify the configuration files according to your needs. Please refer to the official documentation for a complete list of the available options.
Start the container:
```
$ docker-compose up -d
```
Verify that the container is running:
```
$ docker ps
```
If everything is working correctly, you should see a message that says "Up" for the docker-mailserver container.

Conclusion

Congratulations! You have successfully installed docker-mailserver on your EndeavourOS Latest system. You can now use the mail server and configure it as appropriate.
