Dokku - Installation

At many hosters, images containing a full Ubuntu installation including Docker and Dokku can be installed with a single click. This method is very easy and saves a lot of time.

Sometimes the image of the one click install contains and old version of Dokku or is not available at all. The following instructions describe how to install the latest version of Dokku on an Ubuntu (and possibly Debian) host.

Preparation

Install lazydocker: curl https://raw.githubusercontent.com/jesseduffield/lazydocker/master/scripts/install_update_linux.sh | bash

Download the Dokku installer: wget https://raw.githubusercontent.com/dokku/dokku/v0.21.4/bootstrap.sh

Install Dokku: sudo DOKKU_TAG=v0.21.4 bash bootstrap.sh

Update Dokku: sudo apt install -qq -y dokku herokuish sshcommand plugn gliderlabs-sigil

Update the operating system: sudo apt upgrade

Reboot the host: sudo reboot

Installation

Open the IP or domain name of your host in your browser, change the hostname and enable the virtualhost naming option. Save the form and you’re ready to go.
