Requirements

A fresh VM running any of the following operating systems:

• Ubuntu 20.04 / 22.04 x64 - Any currently supported release
• Debian 10+ x64
• 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 -NP . https://dokku.com/install/v0.34.4/bootstrap.sh
sudo DOKKU_TAG=v0.34.4 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.

docker-image-labeler's Issues

There are issue with Dockerfile

Description of problem

Thanks all contributors, this project help me quickly removes labels from docker images.
but I meet some problem when I building Dockerfile:
Error installing fpm
The last version of public_suffix (< 6.0, >= 2.0.2) to support your Ruby & RubyGems was 4.0.7.
Try installing it with gem install public_suffix -v 4.0.7 and then running the current command again.

Steps to reproduce

sudo docker build -f Dockerfile -t docker-image-labeler .

docker-image-labeler version

master

Output of failing command

No response

Question: com.dokku.docker-image-labeler/alternate-tags label

Hello,

why is there a default label com.dokku.docker-image-labeler/alternate-tags added automatically?

Question: setting creation date

Hi,
is there a possibility to set the creation date for the newly created image? Or at least keep the original one?
Currently it's seems to be set to 1.1.1980
