Both the Docker Engine and Docker Compose are necessary dependencies for Feedbacky.

Installation Guide

1. Make sure that your system is up to date.

sudo apt update -y

2. Docker requires some dependencies to be installed on your system.

 sudo apt install -y ca-certificates curl gnupg lsb-release

3. Add Docker's official GPG key.

curl -fsSL | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

4. Use Docker's stable repository.

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

5. Update your system.

sudo apt update -y

6. Install Docker Engine and it's related packages.

sudo apt install -y docker-ce docker-ce-cli

7. Test that the Docker Engine was successfully installed.

sudo docker run hello-world

8. Download the Docker Compose repository.

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

9. Change the permission of downloaded Docker Compose binaries.

MariaDB is recommended over MySQL as it brings better performance but MySQL will still work with Feedbacky if you already have it installed.

Additional configuration needed, do not skip this part if you already have MariaDB installed.

Installation Guide

1. Update your system.

sudo apt update -y

2. Install the MariaDB server package.

sudo apt install -y mariadb-server

3. Run and go through the security script.

sudo mysql_secure_installation

The script will ask you to set a root password, press N to skip it. The root password is already tied to the system on Ubuntu and changing it could result in MariaDB breaking.

Additional Configuration

Docker will treat your container as a remote machine, we need to change the value of bind-address in order to accept non localhost connections.

4. Edit your 50-server.cnf.

sudo nano /etc/mysql/mariadb.conf.d/50-server.cnf

5. Change the value of bind-address to

bind-address            =

6. Save the file with CTRL + S and exit nano with CTRL + C.

7. Restart MariaDB.

sudo systemctl restart mariadb-server

Terminal Multiplexer


During the startup process Feedbacky will use your current terminal window and unless you SSH again in your server with a new session, you won't be able to do anything else.

The solution to this is by using a terminal multiplexer, allowing you to run multiple sessions under a single window.
