Content Security Policy Generator Docker Environment


This is the Docker Compose environment for 4ARMED's Content Security Policy Generator. Basically, using the contents of this repository you can fire up your own instance of the CSP Generator tool, send your CSP violation reports to it via report-uri and then generate an initial policy for your website.


  1. Docker Engine

    I know! Go figure right?! You will need Docker Engine installed and running somewhere. If you want to do this on the Interwebs then Digital Ocean's one click Docker app is a good option.

  2. Docker Compose

    If you use Digital Ocean's one click app it does not come with Docker Compose installed by default so you will need to install it:

    # apt-get update
    # apt-get install docker-compose
  3. TLS Key and Certficate (optional)

    If you are going to send CSP reports from an HTTPS-enabled web site your browser will not allow plain HTTP connections for the report-uri. This means you will need a valid certificate. If this is going on the public Interwebs you may consider buying one.

    You should end up with a private key and a signed certificate from your chosen CA.

Getting Ready

  1. Clone this repo

This must be done on your Docker host as the container makes use of volumes to access the TLS key and certificate.

$ git clone
  1. Install your TLS key and cert

SCP (or some other file transfer) your TLS key and cert onto your Docker host. Both the key and certificate files must be copied to the certs subfolder of this repository clone and named server.key and server.crt respectively.

cd csp-generator
find certs/

In the certs directory you will find a shell script which you can use to generate a self-signed certificate for common name localhost. These will output to sample.key and sample.crt in the current working directory. Move these to server.key and server.crt in the certs folder.

Run it

docker-compose up

At this point Docker Compose will download three images:

  • 4armed/mongo
  • 4armed/nginx
  • 4armed/csp-backend

These are all public on Docker Hub and you can inspect the Dockerfiles etc so you know what they're doing.

You can’t perform that action at this time.
