Database and Web Applications Laboratory
This page describes the computational resources required for the development of the project.
Git is the version control system used during LBAW. The group (gg) repository is: https://git.fe.up.pt/lbaw/lbaw1920/lbaw20gg. The teacher adds you to the repository in the first class.
Make sure you login in https://git.fe.up.pt/ before the first class, so that your account is created in the system.
The repository's README file must include:
The group must ensure that the repository remains private, visible only by the team members and the teacher.
The User Interface Prototype (PIU) is composed by a subset of the user interfaces the group has to develop for the project. The pages are static HTML pages which use the Bootstrap framework.
The group starts the PIU by copying the files available at the template repository https://git.fe.up.pt/lbaw/template-piu to his own repository, and then follow the instructions, detailed in the README, to setup the technologies needed for the development.
The PIU uses the NGINX HTTP server.
A local instance is created inside the Docker container using the bundled
Dockerfile (see the README for the required steps).
Once the PIU HTML pages are developed, the group builds and uploads a Docker image (
lbaw20gg-piu) to the group Docker hub repository (see the README for the required steps).
Using the FEUP VPN, the project will be available at http://lbaw20gg-piu.lbaw-prod.fe.up.pt. Be aware that these interfaces need to be available for evaluation. Otherwise, the group won't be graded in that component.
If you are using your own machine for development you won't likely face the problems described here. If you are using FEUP's desktop computers, you must read this section. Docker server is not installed natively on Windows and Linux, so we need to run it inside a virtual machine.
On Windows, you need to open the Links folder on your desktop and start the Docker-toolbox executable. This will download a virtual machine and set everything for you. Keep the Docker-toolbox window open. Once running, you can use the Docker and Docker-compose binaries that are already set on your Windows Path. Note that as the Docker service is running inside a virtual machine, you do not have access to it using localhost. Instead, you need to use the IP address presented on the Docker-toolbox window.
The process is similar in Linux, but there's no Docker-toolbox available to automatically set up the virtual machine that runs Docker.
We've set one up that you can download it from here.
Note that the image is large and won't likely fit in your user home, you should download it to the
The username and password for the image is "lbaw".
The image is configured to run with a bridged network card, which will provide an IP address with which you can interact with it.
You can check this IP address with
ifconfig command inside the terminal.
You can then use that IP address to instruct your local Docker client to connect to the Docker server running inside the virtual machine, by setting the Docker_HOST environment variable.
Docker is running inside the VM in port 4243, so you can set the variable with
export DOCKER_HOST tcp://192.168.1.30:4243.
Feel free to add this to your bash profile so that it is set on every session.
From here on, you can run Docker commands locally that are executed inside the VM.
PostgreSQL is an object-relational database management system (ORDBMS) used in the course.
A production environment of PostgreSQL is provided, which is used in the application's production version.
Each group (gg) will be provided with a PostgreSQL user account
lbaw20gg, with the group password, and a database
lbaw20gg available on the production machine (
dbm.fe.up.pt) inside FEUP's VPN.
To configure a connection to the database, the following attributes are used:
Host name: dbm.fe.up.pt
Maintenance database: <lbaw20gg>
Password: <group password>
A development environment of PostgreSQL can be used with Docker containers. The group starts by copying the files available at the template repository https://git.fe.up.pt/lbaw/template-postgresql to a new branch of his own repository, and then follow the instructions, detailed in the README, to setup the technologies needed for the development.
The group develops a web application using the Laravel server framework.
The group starts the project by copying the files available at the template repository (https://git.fe.up.pt/lbaw/template-laravel) to their own repository, and then follow the instructions detailed in the README, to set up the development requirements.
The project uses the PostgreSQL database management system. A local instance is created using the bundled Docker compose file (see the README for the required steps to start it).
The group should keep an up to date Docker image of their project at all times in the group's Docker hub repository (see the template README for the required steps).
The group should follow the instructions in the README file to keep the project up to date on their production environment.
Using the FEUP VPN, the project will be available at
The production environment is updated every 60 minutes.
