Requirements
A fresh VM running any of the following operating systems:
- Ubuntu 18.04/20.04 x64 - Any currently supported release
- Debian 9+ x64
- CentOS 7 x64 (experimental)
- Arch Linux x64 (experimental)
An SSH keypair that can be used for application deployment. If this exists before installation, it will be automatically imported into dokku.
Otherwise, you will need to import the keypair manually after installation using dokku ssh-keys:add.
Installation
To install the latest stable release, run the following commands as a user who has access to sudo:
wget https://raw.githubusercontent.com/dokku/dokku/v0.27.0/bootstrap.sh
sudo DOKKU_TAG=v0.27.0 bash bootstrap.sh
You can then proceed to configure your server domain (via dokku domains:set-global) and user access (via dokku ssh-keys:add) to complete the installation.
If you wish for a more unattended installation method, see these docs.
