How to Install MailHog on Fedora CoreOS Latest

In this tutorial, we'll walk you through the process of installing MailHog from Github on Fedora CoreOS Latest.

Prerequisites

A running Fedora CoreOS Latest instance
System privileges (root/sudo access)
A GitHub account

Installation

First, you need to download the MailHog binary from GitHub. You can do this using the wget command:
```
$ wget https://github.com/mailhog/MailHog/releases/download/v1.0.0/MailHog_linux_amd64
```
Next, you need to make the downloaded binary file executable:
```
$ chmod +x MailHog_linux_amd64
```
Then, you need to move the binary file to the /usr/local/bin directory:
```
$ sudo mv MailHog_linux_amd64 /usr/local/bin/mailhog
```
Now that the binary file is installed, you need to create a systemd service file for MailHog. Create a file named mailhog.service in the /etc/systemd/system/ directory:
```
$ sudo nano /etc/systemd/system/mailhog.service
```

Paste the following configuration into this file:

[Unit]
Description=MailHog

[Service]
ExecStart=/usr/local/bin/mailhog

[Install]
WantedBy=multi-user.target

Save and close the file.
Now, you can start the MailHog service by running the following command:
```
$ sudo systemctl start mailhog
```

You can check the status of the MailHog service by running:

$ sudo systemctl status mailhog

If everything is working properly, you should see something similar to the following:

● mailhog.service - MailHog
Loaded: loaded (/etc/systemd/system/mailhog.service; disabled; vendor preset: disabled)
Active: active (running) since Mon 2021-08-02 08:48:46 EDT; 2s ago
Main PID: 977 (mailhog)
Tasks: 6 (limit: 1119)
Memory: 6.0M
CGroup: /system.slice/mailhog.service
    └─977 /usr/local/bin/mailhog

Finally, you can enable the MailHog service to start automatically at boot time by running:
```
$ sudo systemctl enable mailhog
```

Congratulations! MailHog is now installed and ready to use on your Fedora CoreOS Latest instance.
