Platform Installation Instructions¶

This document is for developers / sysadmins who want to install the Rasa platform on premise or on a private cloud.

At a high level, what you need to do is first install Rasa Platform on a server, and then put your own application in a docker container to run alongside it.

Note

Rasa uses docker compose to manage the lifecycle of the containers. The installation script should be used to provision a new server. If you want to run the application alongside other software on an existing server, you should consider installing docker compose manually.

Quickstart¶

copy the license file to the server

scp rasa_platform.yml example.com:~/rasa_platform.yml

Download and run the install script on the server:

curl -sSL -o install.sh https://storage.googleapis.com/rasa-releases/stable/install.sh
sudo bash ./install.sh

Replace stable with a specific version number if you want to install a specific version.

Start the platform

cd /etc/rasaplatform
sudo docker-compose up -d

Create a platform user you can use to login

cd /etc/rasaplatform
sudo python rasa_commands.py create admin USER PASSWORD

Detailed Setup¶

Rasa Platform is built as a collection of docker containers. Here we provide suggested hardware for running on a single server.

Hardware & OS Requirements¶

We recommend 8Gb RAM & 2-6 vCPUs for optimal performance. 4Gb RAM is the bare minimum. Your server should also have 100 Gb Disk space available. You will need a server running a modern Linux distribution that can run docker. The following OS’s work with the easy install script below:

Debian 7.7+
Ubuntu 14.04 / 15.10 / 16.04

For any other operating systems, please follow the manual installation instructions. As long as docker is available for your operating system, Rasa Platform should run fine.

Firewall¶

Make sure the following ports are open:

Port	Service	Description
443	HTTPS	Web application over HTTPS access.
80	HTTP	Web application access.
22	SSH	SSH access.

If you install on Google Cloud this means:

make sure to check “Allow HTTP traffic” as well as “Allow HTTPS traffic” in the firewall settings of the VM instance.

Prepare the installation¶

Before you can install Rasa Platform, you need to have a license file. We will send you that file, it is named rasa_platform.yml. It contains licensing information as well as configuration parameters.

Make sure to upload the license file to the server, e.g. using

scp rasa_platform.yml HOSTNAME:~/rasa_platform.yml

where HOSTNAME is the hostname or ip of your server.

Install Docker Compose¶

Rasa uses docker compose to spin up a collection of docker containers that combined make up the platform. You can either install a specific release, or use latest which corresponds to the most recent release (we recommend pinning a specific version though).

Download the install script and run it. Make sure the current directory contains the license file:

curl -sSL -o install.sh https://storage.googleapis.com/rasa-releases/latest/install.sh
sudo bash ./install.sh

The installation script will install docker compose and ansible. ansible is a popular tool for automation - it will download the docker compose setup as well as prepare the environment for docker to run in.

The platform related files will be installed into /etc/rasaplatform. This includes credentials to login to the docker registry under /etc/rasaplatform/gcr_auth.json.

Note

Although, this is the easiest way to get your server ready to run the platform you can also follow the manual steps which will walk you through a couple more steps but will give you more control over the setup.

Accept the terms and conditions¶

To accept the terms and conditions, run echo "${USER} $(date)" > /etc/rasaplatform/terms/agree.txt. You can find the terms here.

Start the application¶

After you have successfully installed the platform you can now start it:

cd /etc/rasaplatform
sudo docker-compose up -d

This will run the platform in the background (due to -d) and the application will continue to run even if you log out of the server.

Create a User¶

To login into the platform, you need to create user accounts. At first, it is best to create at least one administrator account. To do so run:

cd /etc/rasaplatform
sudo python rasa_commands.py create admin USER PASSWORD

replacing the USER and PASSWORD fields, for example python rasa_commands.py create admin admin PasswOrd.

To create non-admin users, just replace admin with user:

sudo python rasa_commands.py create user USER PASSWORD

Installing Updates¶

How about:

curl -sSL -o install.sh https://storage.googleapis.com/rasa-releases/VERSION/install.sh
sudo bash ./install.sh

replacing VERSION with the version you want to install.

Warning

Be aware, that during the update the following files will be overwritten:

/etc/rasaplatform/docker-compose.yml
/etc/rasaplatform/.env

Make sure there are no changes in these files that you still need. E.g. instead of directly modifying docker-compose.yml you should rather create a new file called docker-compose.override.yml. Docker will automatically take that file into account and override any attributes in docker-compose.yml with changes from the override file.

Next Steps¶

Now that you have the main pieces of the platform installed, you can go ahead and run the Deploy an Example App.

Manual Installation¶

Make sure python, docker, and docker compose are installed on your platform. Detailed instructions can be found in the docker documentation. You should be able to run
docker-compose --version

Create the project directory and switch to it:

mkdir /etc/rasaplatform
cd /etc/rasaplatform

Download the platform files (docker-compose.yml and rasa_commands.py) that contain the containers and their setup (replacing latest with the version to install):

wget -qO docker-compose.yml https://storage.googleapis.com/rasa-releases/latest/docker-compose.yml
wget -qO rasa_commands.py https://storage.googleapis.com/rasa-releases/latest/rasa_commands.py

Create the authentication file to download containers from the docker registry. To authenticated with the registry that contains the platform containers, you need to create a file in /etc/rasaplatform/gcr-auth.json that contains the JSON of the field docker_registry_license from your license.

Make sure to copy everything between the outer " of the docker_registry_license key to that file. The contents of /etc/rasaplatform/gcr-auth.json should look like this:

{
  "type": "service_account",
  "project_id": "rasa-platform",
  "private_key_id": "sdferw234qadst423qafdgxhw",

Login to the docker registry

sudo docker login  -u _json_key -p "$(cat /etc/rasaplatform/gcr-auth.json)" https://gcr.io

Create the docker environment file in /etc/rasaplatform/.env with the following content:
RASA_PYPI_PASSWORD=<pypi_repository_password> RASA_PYPI_USER=<pypi_repository_user> RASA_NLU_TOKEN=<random_string> RASA_CORE_TOKEN=<random_string> PASSWORD_SALT=<random_string> TOKEN_SALT=<random_string> MONGO_PASSWORD=<random_string>
Filling in the values of <pypi_repository_password> and <pypi_repository_user> from your license file. For <random_string> please use secure strings, e.g. randomly generated character sequences.

For the token and password salt fields, enter any string of your choice. These will be used to hash passwords. Note that if you change these you will have to create new logins for everyone.

You will also need to set a Rasa NLU and Rasa Core Token. These are needed to ensure only you have access.
Note

Make sure to generate a different unique <random_string> for each field! E.g. running this multiple times:
openssl rand -base64 12
Start up the platform (-d will run the platform in the background):
sudo docker-compose up -d
