Installation¶

Docker (recommended)¶

If you are on a Linux machine you will need Docker installed or if you are using a Windows or Mac OS X machine you will need boot2docker.

You can run Portia with the command below:

docker run -i -t --rm -v <PROJECTS_FOLDER>:/app/data/projects:rw -p 9001:9001 scrapinghub/portia

Portia will now be running on port 9001 and you can access it at http://localhost:9001. Projects will be stored in the project folder that you mount to docker.

To extract data using portia you can run your spider with:

docker run -i -t --rm -v <PROJECTS_FOLDER>:/app/data/projects:rw -v <OUPUT_FOLDER>:/mnt:rw -p 9001:9001 scrapinghub/portia \
    portiacrawl /app/data/projects/PROJECT_NAME SPIDER_NAME -o /mnt/SPIDER_NAME.jl

After the crawl finishes you will find your extracted data in the the OUTPUT_FOLDER

Note

<PROJECT_FOLDER> qne <OUTPUT_FOLDER> are just paths on your system where your projects and extracted data are stored.

Warning

For Windows the <PROJECT_FOLDER> path must be of the form /<DRIVE_LETTER/<PATH>. For example /C/Users/UserName/Documents/PortiaProjects

Vagrant¶

Checkout the repository:

$ git clone https://github.com/scrapinghub/portia

You will need Vagrant , VirtualBox Node.js, Bower and ember-cli installed.

Run the following in Portia’s directory:

docker/compile-assets.sh
vagrant up

This will launch an Ubuntu virtual machine, build Portia and start the portia server. You’ll then be able to access Portia at http://localhost:9001. You can stop the portia server using vagrant suspend or vagrant halt. To run portiacrawl you will need to SSH into the virtual machine by running vagrant ssh.

Ubuntu¶

Running Portia Locally¶

These instructions are only valid for an Ubuntu based OS

Install the following dependencies:

sudo ./provision.sh install_deps

If you would like to run Portia locally you should create an environment with virtualenv:

virtualenv YOUR_ENV_NAME --no-site-packages
source YOUR_ENV_NAME/bin/activate
cd ENV_NAME

Now clone this repository into that env:

git clone https://github.com/scrapinghub/portia.git
cd portia

Install splash and the required packages:

sudo ./provision.sh install_deps install_splash install_python_deps

To run Portia start slyd and portia_server:

PYTHONPATH='/vagrant/portia_server:/vagrant/slyd:/vagrant/slybot'
slyd/bin/slyd -p 9002 -r portiaui/dist &
portia_server/manage.py runserver

Portia should now be running on port 9001 and you can access it at http://localhost:9001.

Developing Portia using Docker¶

To develop Portia using docker you will need Node.js, Bower and ember-cli installed.

To set up Portia for development use the commands below:

mkdir ~/data
git clone git@github.com:scrapinghub/portia.git
cd portia/portiaui
npm install && bower install
cd node_modules/ember-cli && npm install && cd ../../
ember build
cd ..
docker build . -t portia

You can run it using:

docker run -i -t --rm -p 9001:9001 \
    -v ~/data:/app/data/projects:rw \
    -v ~/portia/portiaui/dist:/app/portiaui/dist \
    -v ~/portia/slyd:/app/slyd \
    -v ~/portia/portia_server:/app/portia_server \
    portia

This sets up the portia_server to restart with every change you make and if you run cd ~/portia/portiaui && ember build -w in another shell you can rebuild the Portia assets with every change too.
