         # add docker software repository
         sudo add-apt-repository "deb [arch=$(dpkg --print-architecture)] download.docker.com/linux/$(awk -F'=' '/^ID=/{ print $NF }' /etc/os-release) $(lsb_release -cs) stable"
         # install docker
         sudo apt install docker-ce docker-compose containerd.io -y
         # enable and start docker service
         sudo systemctl enable docker && sudo systemctl start docker
         # add the current user to the docker group
         sudo usermod -aG docker $USER

         mkdir ~/docker/mattermost/{config,data,logs,plugins,client/plugins,bleve-indexes} -p
         # create a copy of .env
         cp ~/docker/mattermost/env.example ~/docker/mattermost/.env
         # set owner of working directories
         sudo chown "$USER":"$USER" ~/docker -R
         # allow the container to write to working directories
         sudo chmod a+rwx -R ~/docker/mattermost
         # replace default paths
         sudo sed -i "s|/volumes||" ~/docker/mattermost/.env
         # edit .env
         nano ~/docker/mattermost/.env
