After I ran the dokku installation script on my fresh new Ubuntu system, the console outputed such error:
This installation script requires that you have a hostname set for the instance. Please set a hostname for 127.0.0.1 in your /etc/hosts
The solution, indeed, is fairly simple. You only need to add the following lines to the /etc/hosts
and /etc/hostname
files:
// This line goes to /etc/hosts
YOUR_IP YOUR_URL YOUR_HOSTNAME
// This line must be included in your /etc/hostname file
YOUR_HOSTNAME
Then, you can test it by hostname -f
.
