Docker-OpenWISP

Automation Tests GitLab Container Registery Gitter Support GitHub license

This repository contains official docker images of OpenWISP. Designed with horizontal scaling, easily replicable deployments and user customization in mind.

kubernetes The sample files for deployment on kubernetes are available in the deploy/examples/kubernetes/ directory.

0.1.0a6 0.13.2+

* Roughly the same features would be available but it's not an exact one-to-one mapping.

Architecture

Architecture

  • openwisp-dashboard: Your OpenWISP device administration dashboard.
  • openwisp-api: HTTP API from various openwisp modules which can be scaled simply by having multiple API containers as per requirement.
  • openwisp-radius: HTTP API for interacting with openwisp-radius. Separated from the rest of APIs as it can have different scalability requirements in large deployments.
  • openwisp-websocket: Dedicated container for handling websocket requests, eg. for updating location of mobile network devices.
  • openwisp-celery: Runs all the background tasks for OpenWISP, eg. updating configurations of your device.
  • openwisp-celerybeat: Runs periodic background tasks. eg. revoking all the expired certificates.
  • openwisp-nginx: Internet facing container that facilitates all the HTTP and Websocket communication between the outside world and the service containers.
  • openwisp-freeradius: Freeradius container for OpenWISP.
  • openwisp-openvpn: OpenVPN container for out-of-the-box management VPN.
  • openwisp-postfix: Mail server for sending mails to MTA.
  • openwisp-nfs: NFS server that allows shared storage between different machines. It does not run in single server machines but provided for K8s setup.
  • openwisp-base: It is the base image which does not run on your server, but openwisp-radius, openwisp-api & openwisp-dashboard use it as a base.
  • Redis: data caching service (required for actions like login).
  • PostgreSQL: SQL database container for OpenWISP.

Deployment

Quick Setup

The auto-install.sh script can be used to quickly install a simple instance of openwisp on your server.

Quick Install

If you have created a .env file to configure your instance, then you can use it with the script otherwise.

It asks 6 questions for application configuration, 4 of them are domain names. The dashboard, api, radius & openvpn can be setup on different domain, please ensure the domains you enter point to your server. The remaining 2 questions are email id for site manager email (used by django to send application emails) and letsencrypt (used by certbot to issue https certs on this address.)

To get started, run the following command:

   curl -L https://bit.do/auto-install -o setup.sh
   sudo bash setup.sh
   # If you are upgrading from an older version setup by this script use
   # sudo bash setup.sh --upgrade
   # For more information
   # sudo bash setup.sh --help

Note: Facing errors while installation? Please read the FAQ.

Compose

Setup on docker-compose is suitable for single-server setup requirements. It is quicker and requires less prior knowledge about openwisp & networking.

Kubernetes

Setup on kubernetes is complex and requires prior knowledge about linux systems, kubernetes, docker & openwisp. However, it provides scalability for very large networks.

Customization

Workbench setup

  1. Install docker & docker-compose.
  2. In the root of the repository, run make develop, when the containers are ready, you can test them out by going to the domain name of the modules.

Notes:

  • Default username & password are admin.
  • Default domains are: dashboard.openwisp.org, api.openwisp.org and radius.openwisp.org.
  • To reach the dashboard you may need to add the openwisp domains set in your .env to your hosts file, example: bash -c 'echo "127.0.0.1 dashboard.openwisp.org api.openwisp.org radius.openwisp.org" >> /etc/hosts'
  • Now you'll need to do steps (2) everytime you make a changes and want to build the images again.
  • If you want to perform actions like cleaning everything produced by docker-openwisp, please use the makefile options.

Changing Python Packages

You can build with your own python package by creating a file named .build.env in the root of the repository, then set the variables inside .build.env file in <variable>=<value> format. Multiple variable should be separated in newline. These are the variables that can be changed:

  • OPENWISP_MONITORING_SOURCE
  • OPENWISP_FIRMWARE_SOURCE
  • OPENWISP_CONTROLLER_SOURCE
  • OPENWISP_NOTIFICATION_SOURCE
  • OPENWISP_TOPOLOGY_SOURCE
  • OPENWISP_RADIUS_SOURCE
  • OPENWISP_USERS_SOURCE
  • OPENWISP_UTILS_SOURCE
  • OPENWISP_IPAM_SOURCE
  • DJANGO_SOURCE
  • DJANGO_NETJSONCONFIG_SOURCE
  • DJANGO_X509_SOURCE

For example, if you want to supply your own django and openwisp-controller source, your .build.env should be written like this:

DJANGO_SOURCE=django==3.2
OPENWISP_CONTROLLER_SOURCE=https://github.com/<username>/openwisp-api/tarball/master

Disabling Services

Right now, this is only tentative guide. Errata may exist. Please report errors on the gitter channel.

  • openwisp-dashboard: You cannot disable the openwisp-dashboard. It is the heart of OpenWISP and performs core functionalities.
  • openwisp-api: You cannot disable the openwisp-api. It is required for interacting with your devices.
  • openwisp-websocket: Removing this container will cause the system to not able to update real-time location for mobile devices.

If you want to disable a service, you can simply remove the container for that service, however, there are additional steps for some images:

  • openwisp-network-topology: Set the USE_OPENWISP_TOPOLOGY variable to False.
  • openwisp-firmware-upgrader : Set the USE_OPENWISP_FIRMWARE variable to False.
  • openwisp-monitoring : Set the USE_OPENWISP_MONITORING variable to False.
  • openwisp-radius : Set the USE_OPENWISP_RADIUS variable to False.
  • openwisp-postgres: If you are using a seperate database instance,
    • Ensure your database instance is reachable by the following OpenWISP containers: openvpn, freeradius, celerybeat, celery, websocket, radius, api, dashboard.
    • Ensure your database server supports GeoDjango. (Install PostGIS for PostgreSQL)
    • Change the database configuration variables to point to your instances, if you are using SSL, remember to set DB_SSLMODE, DB_SSLKEY, DB_SSLCERT, DB_SSLROOTCERT.
    • If you are using SSL, remember to mount volume containing the certificates and key in all the containers which contact the database server and make sure that the private key permission is 600 and owned by root:root.
    • In your database, create database with name <DB_NAME>.
  • openwisp-postfix:

Runtests

You can run tests either with geckodriver (firefox) or chromedriver (chromium). Chromium is preferred as it checks for console log errors as well.

  1. Setup driver for selenium:

    • Setup chromedriver

      1. Install: sudo apt --yes install chromium
      2. Check version: chromium --version
      3. Install Driver for your version: https://chromedriver.chromium.org/downloads
      4. Extract chromedriver to one of directories from your $PATH. (example: /usr/bin/)

    • Setup geckodriver

      1. Install: sudo apt --yes install firefox
      2. Check version: firefox --version
      3. Install Driver for your version: https://github.com/mozilla/geckodriver/releases
      4. Extract geckodriver to one of directories from your $PATH. (example: /usr/bin/)

  2. Install selenium: python3 -m pip install selenium

  3. (Optional) Configure: open tests/config.json and configure variables as per your requirement, options are:

    driver: Name of driver to use for tests, "chromium" or "firefox"
logs: print container's logs if an error occurs.
logs_file: Location of the log file for saving logs generated for tests.
headless: Run selenium chrome driver in headless mode
load_init_data: Flag for running tests/data.py, only needs to be done once after database creation
app_url: URL to reach the admin dashboard
username: username for logging in admin dashboard
password: password for logging in admin dashboard
services_max_retries: Maximum number of retries to check if services are running
services_delay_retries: Delay time (in seconds) to each retries for checking if services are running

  4. Run tests: make runtests

Note: To run a single test use the following command

python3 tests/runtests.py <TestSuite>.<TestCase>
# python3 tests/runtests.py TestServices.test_celery

Makefile Options

Most commonly used:

  • start<USER=docker-username> <TAG=image-tag>: Start OpenWISP containers on your server.
  • pull<USER=docker-username> <TAG=image-tag>: Pull Images from registry.
  • stop: Stop make containers on your server.
  • develop: Bundles all the commands required to build the images and run containers.
  • runtests: Run testcases to ensure all the services are working.
  • clean: Aggressively purge all the containers, images, volumes & networks related to docker-openwisp.

Other options:

  • publish <USER=docker-username> <TAG=image-tag>: Build, test and publish images.
  • python-build: Generate a random django secret and set it in the .env file.
  • nfs-build: Build openwisp-nfs server image.
  • base-build: Build openwisp-base image. The base image is used in other OpenWISP images.
  • compose-build: (default) Build OpenWISP images for development.
  • develop-runtests: Similar to runtests, it runs the testcases except doesn't stop the containers after running the tests which maybe desired for debugging & analyzing failing container's logs.
