🗂️ CREATE A FOLDER AND IMPORT REPO
sudo mkdir /mnt/docker/decidim
cd /mnt/docker/decidim

sudo chown -R root: code

🚀 RUN IT!
cd /mnt/docker/decidim/code/0.28.0
docker-compose up -d

👤 ADD SUPER ADMIN
open console in 'decidim' container via ssh (docker exec -it container_name /bin/bash) or in Portainer
and enter these commands one after another

bundle exec rails console
user = Decidim::System::Admin.new(email: 'myemail@address.net', password: 'SuperAdminPass', password_confirmation: 'SuperAdminPass')
user.save!

then exit

🌐 URL
create a URL (domain.net) or sub-domain (sub.domain.net) and point it to your serveur IP
depending on your server set apache, nginx or traefik to point to the container's port, here: 3000

goto URL : sub.domain.net/system

LOGIN with SuperAdmin credentials
CREATE new organisation
OPEN Advanced Settings to access SMTP details (see if port 587 is better then 465)
SAVE

📧 CHECK if you received the confirmation email - change SMTP settings if necessary

♻️ UPDATE CODE
cd /mnt/docker/decidim/code/0.28.0/config/environments
sudo nano production.rb

add this line in the block Rails.application.configure do ... end :
config.hosts << "sub.domain.net"

⚙️ RESTART CONTAINER
sudo docker compose restart app

🌐 GOTO URL sub.domain.net/admin
give a new password for your admin account

🏆 INITIATE your project

👃 SMELL YOUR FINGERS
they smell goood

GIVE THEM a V for Victory ✌️

Extra data

• Decidim Version: 0.28.0
• Decidim installation: docker-compose or portainer stack
• Revolution: one command at a time - unless stopped

Additional context

this is a need for less-tech people, that would like to start a revolution in their community
I'd be very happy to receive your comments after you tried my recipe

✌️ love will prevail

@punkyard Big thanks for this! This help me a lot

Also I have some improvments to your docker-compose.yml...
I added sed to command, so there is no need to edit files or monting local, just use image from docker hub:

command: bash -c "
      sed -i \"s/^end$/  config.hosts << \\\"YOUR.FULL.DOMAIN.HERE.social\\\"\\nend/\"  config/environments/production.rb
       bundle exec rake db:migrate && bundle exec puma -C config/puma.rb
      "
