This is documentation for Rasa X Documentation v0.32.x, which is no longer actively maintained.
For up-to-date documentation, see the latest version (0.33.x).

Version: 0.32.x

Docker Compose Installation

In this installation method, Rasa X is deployed on a server as a set of Docker containers.

An install script is available for servers that meet the hardware and OS requirements. For other operating systems, you can install Rasa X via Docker Compose manually.

Requirements

note

Rasa X is intended to be deployed on a server and not to a personal/local machine. Deploying on a server is recommended because Rasa X is designed to stay up continuously, and not to be frequently stopped or restarted.

Hardware & OS Requirements

Here are the minimum and recommended hardware specs and OS requirements:

Install ScriptManual Installation
Operating System Ubuntu 16.04 / 18.04 / 19.10 Debian 9 / 10 CentOS 7 / 8 RHEL 8a modern Linux or Windows distribution that can run Docker
vCPUs Minimum: 2 vCPUs Recommended: 2-6 vCPUs
RAM Minimum: 4 GB RAM Recommended: 8 GB RAM
Disk Space* Recommended: 100 GB disk space available

Port Requirements

When creating the server, make sure the following ports of are open:

PortServiceDescription
22SSHSSH access.
80HTTPWeb application access.
443HTTPSWeb application over HTTPS access (optional)

Supported Browsers

The web interface aims to support browsers that meet the following criteria:

  • 0.2% market share

  • not Internet Explorer

  • not Opera Mini


Docker Compose Install Script

Watch the Rasa Masterclass video below to follow along with the install script instructions:

If you have a Rasa Enterprise license, please see the Enterprise instructions where applicable.

1. Download

Download the install script:

Download the install script on the server:
curl -sSL -o install.sh https://storage.googleapis.com/rasa-x-releases/0.32.2/install.sh

2. Install

To install all of the files into the default folder, /etc/rasa, run:

sudo bash ./install.sh

You will be prompted to accept the terms and conditions. Read the terms, then hit return to continue.

note

To choose your own installation folder instead of /etc/rasa, set the RASA_HOME environment variable:

export RASA_HOME=~/rasa/dir
sudo -E bash ./install.sh # -E will preserve the environment variable you set

Replace /etc/rasa with ${RASA_HOME} in further commands.

3. Start

Start up Rasa X and wait until all containers are running (-d will run Rasa X in the background):

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

4. Access

Set your admin password:

Set your admin password with this command:
cd /etc/rasa
sudo python rasa_x_commands.py create --update admin me <PASSWORD>

Navigate to the hostname or IP where your server is reachable and log in using your newly created password.

Docker Compose Manual Install

We provide template docker-compose files which you can use directly. The Docker images for Rasa X are freely available via Docker Hub. The images for Rasa Enterprise are hosted on a private registry and are accessible with an enterprise license. If you have a Rasa Enterprise license, please see the Enterprise instructions where applicable.

1. Prerequisites

Make sure python3, docker, and docker-compose are installed on your server. Detailed instructions can be found in the Docker documentation.

You should be able to run the following command(s):

python3 --version && docker -v && docker-compose -v

Note that your python version should be above 3.6 to use Rasa and Rasa X.

2. Set Project Directory

Create the project directory and switch to it:

For example, /etc/rasa
mkdir /etc/rasa
cd /etc/rasa

3. Download

Download the Rasa X docker-compose and commands files:

wget -qO docker-compose.yml https://storage.googleapis.com/rasa-x-releases/0.32.2/docker-compose.ce.yml
wget -qO rasa_x_commands.py https://storage.googleapis.com/rasa-x-releases/0.32.2/rasa_x_commands.py

4. Configure

Docker Environment File

Create the docker environment file .env in your project directory with the following content (choosing a RASA_VERSION compatible with your RASA_X_VERSION - see the Compatibility Matrix):

RASA_X_VERSION=<rasa_x_version>
RASA_VERSION=<rasa_version>
RASA_TOKEN=<random_string>
RASA_X_TOKEN=<random_string>
PASSWORD_SALT=<random_string>
JWT_SECRET=<random_string>
RABBITMQ_PASSWORD=<random_string>
DB_PASSWORD=<random_string>
REDIS_PASSWORD=<random_string>

For <random_string> please use a distinct, randomly generated, secure character sequence for each variable. A convenient way of generating random strings is using openssl:

openssl rand -base64 16

For more information about these environment variables and others used by Rasa X, see Environment Variables.

note

The PASSWORD_SALT is used to hash passwords. If you change this variable after setting it, you will have to create new logins for each of your users.

Credentials

Create a credentials file credentials.yml in your project directory containing:

rasa:
url: ${RASA_X_HOST}/api

These are the credentials used for messaging with the bot via the Rasa X UI. You can also add credentials for other messaging and voice channels such as your custom connector or the REST input channel.

Endpoints

Create an endpoints file endpoints.yml in your project directory containing:

models:
url: ${RASA_MODEL_SERVER}
token: ${RASA_X_TOKEN}
wait_time_between_pulls: ${RASA_MODEL_PULL_INTERVAL}
tracker_store:
type: sql
dialect: "postgresql"
url: ${DB_HOST}
port: ${DB_PORT}
username: ${DB_USER}
password: ${DB_PASSWORD}
db: ${DB_DATABASE}
login_db: ${DB_LOGIN_DB}
lock_store:
type: "redis"
url: ${REDIS_HOST}
port: ${REDIS_PORT}
password: ${REDIS_PASSWORD}
db: ${REDIS_DB}
event_broker:
type: "pika"
url: ${RABBITMQ_HOST}
username: ${RABBITMQ_USERNAME}
password: ${RABBITMQ_PASSWORD}
queue: ${RABBITMQ_QUEUE}
action_endpoint:
url: ${RASA_USER_APP}/webhook
token: ""

If you want to know more about the environment variables used here, see Environment Variables.

Deployment Environments

Create an environments file at environments.yml in your project directory containing:

rasa:
production:
url: http://rasa-production:5005
token: ${RASA_TOKEN}
worker:
url: http://rasa-worker:5005
token: ${RASA_TOKEN}

If you are using Rasa Enterprise, you can also add further environments as described in Deployment Environments.

Mounted Directories

Create a few empty folders that we will mount into the containers:

mkdir /etc/rasa/auth
mkdir /etc/rasa/certs
mkdir /etc/rasa/credentials
mkdir /etc/rasa/models
mkdir /etc/rasa/logs
mkdir /etc/rasa/terms
mkdir /etc/rasa/db

Terms

Read the Rasa Enterprise terms or Rasa X terms. To agree to the terms, create an agreement file in the terms folder:

touch /etc/rasa/terms/agree.txt

Permissions on Mounted Directories

Set group and permissions of the mounted directories:

The Rasa containers are following Docker’s best practices and are not running as `root` user. Hence, please make sure that the `root` group has read and write access to the following directories and their content:

  • /etc/rasa/credentials.yml

  • /etc/rasa/endpoints.yml

  • /etc/rasa/environments.yml

  • /etc/rasa/auth

  • /etc/rasa/certs

  • /etc/rasa/credentials

  • /etc/rasa/models

  • /etc/rasa/logs

  • /etc/rasa/terms

To set the permissions and group for everything in `/etc/rasa` you can use this command, but make sure to correct it for the `/etc/rasa/db` directory as described in the next step:

sudo chgrp -R root /etc/rasa/* && sudo chmod -R 770 /etc/rasa/*

If you are mounting different or extra directories, please adapt their permissions accordingly.

Postgres Database Storage

Configure persistent Postgres database storage

On Linux, a local directory is used for persistent Postgres database storage.
You must set the correct owner and permissions of the database persistence directory using this command:

sudo chown -R 1001 /etc/rasa/db && sudo chmod -R 750 /etc/rasa/db

(Optional) Custom Action Server

If you are using custom actions, make sure to follow the instructions to connect a custom action server.

If you don’t want to configure custom actions yet, make sure to add this variable to your .env to use the demo app image:

RASA_X_DEMO_VERSION=<rasa_x_version>

5. Start

Start up Rasa X and wait until all containers are running (-d will run Rasa X in the background):

sudo docker-compose up -d

6. Access

Set your admin password with this command from your project directory:

sudo python rasa_x_commands.py create --update admin me <PASSWORD>

Navigate to the hostname or IP where your server is reachable and log in using your newly created password.
