Before running the backend installation commands, make sure your system have the following packages installed:

• gnupg2 : GNU privacy guard - a free PGP replacement

• pass : lightweight directory-based password manager

• make : to be able to use the provided tool (Makefile) to install the backend

• docker.io (or equivalent)

• docker-compose (or equivalent)

Admin privileges

Some backend installation commands will require admin priviledges. Make sure your current user is part of the sudoers group. Edit the /etc/sudoers file and add your user to it:

<username> ALL=(ALL)  ALL

Ubuntu/Debian like systems

The installation process on Ubuntu/Debian like systems is quite easy.

sudo apt install -y docker.io docker-compose gnupg2 pass make

RedHat/CentOS like systems

The installation process on those machines is a bit more complex.

Some packages are already part of the standard repository and can be installed right away.

sudo dnf install -y gnupg2 make

Docker (docker.io equivalent)

To install docker packages, please add the Docker repository to your configuration manager:

sudo dnf config-manager --add-repo=https://download.docker.com/linux/centos/docker-ce.repo

Then, you can install docker with the following command:

sudo dnf install -y docker-ce docker-ce-cli containerd.io

Unlike Ubuntu/Debian systems, Docker needs to be started once manually to be set up:

sudo systemctl enable --now docker

Docker-compose

Docker-compose needs to be installed from the official site. Please execute the following commands:

sudo curl -L "https://github.com/docker/compose/releases/download/1.27.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

Pass

Pass’ official name is password-store. It seems like it used to be part of RedHat/CentOS standard repository, but not anymore. You can download the latest official version from this link.

To install it, simply run:

tar xvf password-store-x.y.z.tar.xz
cd password-store-x.y.z
sudo make install

Docker group

To be able to execute some Docker commands, the current user will need to be added to the Docker group. To do so, open file /etc/group and append the current username to the “docker” line:

docker:x:<groupid>:<username>
