Docker & docker-compose Installation

That's official Docker install script for Debian:

cd /usr/local/src && wget -qO- | sh

Run Docker service:

sudo systemctl start docker

And download docker-compose - yeah, just download it:

sudo curl -L$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

Monaba Installation

Option #1. Plain Docker

Open your CLI and type:

git clone && cd Monaba

Set up some local dependencies by running build script:


The previous command has just created settings.yml file that contains all run configurations. All you want to edit is under CUSTOMIZE section.

Pull Docker images

Once you're ready to go further let's get all docker images by running this command:

docker-compose pull

Or build them by yourself:

docker-compose build

It takes rather long time so be patient.


Start the application:

docker-compose up -d

Visit /admin/setup page and use admin both for login and password to log in admin panel.

The maximum files size is hardcoded and can be changed in Foundation.hs before building. Default value is 25 MB. After you made your changes, docker image must be rebuilt:

docker-compose build app

Option #2. Docker Swarm

Assuming you have a server on with ssh access for user ahushh.

Open terminal on your local machine and follow the instructions.

Create SSH key and add it to our server:

ssh-keygen -f ~/.ssh/monaba

ssh-copy-id -i ~/.ssh/monaba

Create docker instance on the server:

docker-machine create --driver generic --generic-ip-address --generic-ssh-user ahushh --generic-ssh-key ~/.ssh/haibane1 --engine-storage-driver=overlay2 monaba

Connect to the server using SSH:

docker-machine ssh monaba

Install docker & docker-compose, clone repository and change dir, run script:

See the previous sections. 

Initialize Docker Cluster:

docker swarm init


This command pulls the latest monaba images from registry and runs everything:

docker stack deploy --compose-file docker-compose.yml monaba
