REMP

Apps

Each of the REMP services provides its own description and integration documentation - you can access it by clicking one of the headings below.

Following is a brief description of REMP services included in this mono-repository.

SSO

SSO is the single point of authentication in the default REMP tools configuration. Currently, it allows users of REMP tools (Beam, Campaign, Mailer) to log in via their Google accounts.

It also serves as an authentication tool for API requests across the REMP tools - you can manage your API keys within the web administration of the SSO.

In the future we plan to make easier to develop other authentication mechanisms to connect and also proper authorization management for users.

Beam

Beam is primary tool for tracking all events across the system and providing aggregated data for statistical components in Beam and other REMP services.

You can track pageview related events right from the Javascript on your website or call an API from backend.

Beam admin provides a way to display real time usage stats on your website, aggregated article/author/conversion data and allows you to create user segments based on the tracked data.

Campaign

Campaign is a tool for easy creation and showing of banners on your website. In the banner definition you can configure how the banner should look like, where it should be displayed and what it should include.

In the campaign definition you can configure who should see the banner and how often.

If Beam is installed, you can use user segments in configuration who should see the banner. You can also link other segment providers (e.g. your own CRM) to provide other user segments.

Mailer

Mailer provides a way to manage emails (layouts and templates) which can be sent as newsletters. Mailer provides APIs for managing user's newsletter subscriptions, handles batch sending of emails and A/B testing.

To complement all users subscribed to newsletter, you're able to use user segment when sending a newsletter. Therefore, only users belonging to the selected segment which are also subscribed to the newsletter will receive an email. In the default configuration, Beam segments are available. You can link your own segment provider (e.g. your own CRM) to provide other user segments.

In a default implementation SMTP and Mailgun mailer providers are implemented. You can extend the implementation with your own Mailer provider if you need it.

Install

Docker installation

(recommended for development or testing)

1. Pre-building binaries of Go apps

There's a need for pre-building binaries of Go apps before you can run Docker compose. You don't need Go environment to have set up, but you need Docker to build docker-ready tarballs properly.

make docker-build

2. Docker Compose

We've prepared docker-compose.yml in a way it's ready for development.

docker compose up

After pulling new code, if changes where made to Docker/php/Dockerfile or any composer.lock files run:

docker compose up --build

The appliance was tested with Docker Engine - Community 23.0 and Docker Compose 2.16.0.

2.1 User rights in the container

Since REMP 1.3, Docker Compose appliance supports passing the currently logged user to the containers to make sure there are not any access rights issues within the containers.

To correctly pass information about your user to Docker Compose, create .env file in the root of the project (based on the .env.example). If the Docker compose cannot find the information, it will default to the docker user with UID:GID of 1000:1000.

3. First run

If some application doesn't have .env file, docker will assume it's not installed and it will automatically proceed with all required steps to install project. It will:

• create .env file,
• install all the dependencies (composer & yarn),
• prepare the DB structure and insert demo data.

You can see what is installed in Docker/php/remp.sh.

4. Override services & enviroment settings

Feel free to override/add services via docker-compose.override.yml.

This is an excerpt of override we use. It handles proper connection of XDebug to host machine, exposing services running outside of this appliance (such as our internal CRM) and caching of yarn/composer packages.

We highly recommend to place the yarn/composer cache volumes to all PHP-based services, but only after the first run. Otherwise, the installation of project would be downloading the packages simultaneously and would be overriding stored packages in cache. This would cause an error.

version: "3"

services:
  campaign:
    environment:
      XDEBUG_CONFIG: "remote_host=172.17.0.1"
    extra_hosts:
      - "crm.press:172.17.0.1"
    volumes:
      - "/home/developer/.cache/composer:/composer:rw"
      - "/home/developer/.cache/yarn:/yarn:rw"

  mysql:
    volumes:
      - ".:/data"

You can also override environment variables in .env file of each project. After first run this file contains default values (copy of .env.example).

5. Hosts

Application exposes all services via Nginx container. Following is list of available hosts. We advise you to add them to your /etc/hosts:

# CAMPAIGN
127.0.0.1 campaign.remp.press # web administration

# MAILER
127.0.0.1 mailer.remp.press # web administration

# BEAM
127.0.0.1 beam.remp.press # web administration
127.0.0.1 tracker.beam.remp.press # event tracker API; swagger @ http://tracker.beam.remp.press/swagger.json
127.0.0.1 segments.beam.remp.press # segments API; swagger @ http://segments.beam.remp.press/swagger.json

# SSO
127.0.0.1 sso.remp.press # web administration and API

# SERVICE APPS
127.0.0.1 adminer.remp.press # adminer for manipulating with MySQL
127.0.0.1 mailhog.remp.press # mailhog for catching and debugging sent emails
127.0.0.1 kibana.beam.remp.press # kibana for manipulating with Elastic data

Note: If you use Docker Toolbox, the IP won't be 127.0.0.1. Use docker-machine ls to get IP address of the machine.

6. Integration

To integrate Beam and Campaign with your website you need to include javascript into your page. Consult part javascript snippets within READMEs - Beam#javascript-snippet and Campaign#javascript-snippet.

Manual installation

Please use docker-compose.yml and configuration/scripts within Docker folder as a reference for manual installation of each service.

Steps to install dependencies of each project are part of README file for that particular service.

Be aware of .env.example files across projects. These need to be copied to .env and configured based on your configuration.

Docker Compose

If you're unfamiliar with docker-compose, try running docker compose --help as a starter. Each of the subcommands of Docker also supports its own --help switch. Feel free to explore it.

Couple of neat commands:

• docker compose down to remove all containers, networks and volumes created by docker-compose
• docker compose ps to list all services with their status
• docker compose logs to read services logs
• docker compose build to force rebuild of images
• docker compose exec campaign /bin/bash to connect to campaign container
• docker images to list all available docker images

PHP Debugging

Docker compose and custom images are pre-installed with XDebug and pre-configured for PHPStorm debugger. All you need to do is set folder mapping within your IDE for each debuggable host.

Error tracking

All PHP applications are preconfigured to use Airbrake error tracking - see .env.example for configuration options.

We recommend to use self-hosted Errbit instance as it's compatible with Airbrake APIs and completely open-source.

Running behind proxy

You might want to run your application on https, but internally use load balancers and forward requests to handlers via http.

By default the applications determine protocol of generated URLs based on the incoming request protocol. In scenario described above this would cause http links to be generated on https page visit.

To enforce https generation, you can use FORCE_HTTPS environment variable changing the behavior in all web applications. See .env.example files for configuration options.

Known issues

• PHP images are coming with preinstalled and always-on XDebug. We made the always-on choise for easier debugging and availability to debug also console scripts. However, if it can't connect to the host machine, it slows down the request because it waits for connection timeout. Therefore, is very important to have proper XDEBUG_CONFIG variables configured in your docker-compose.override.yml.

• Windows is pushing scripts to Docker with CRLF new lines which is causing issues described in this blog. Clone your repository with extra --config core.autocrlf=input parameter and set your IDE to save files with LF line endings.

• Telegraf gets stuck if requested topic doesn't exist yet. This has been reported and "hacked" with dockerize, custom topic creation and waits. This is not 100% bulletproof and will be fixed when Telegraf 1.4 is released.

• If you're using Docker Toolbox with VirtualBox and your workspace is outside your $HOME folder, you need to add shared folder to your appliance so the Docker containers are able to work with shared volumes properly.

  VBoxManage.exe sharedfolder add default --automount --name 'd/gospace' --hostpath '\\?\d:\gospace'
  VBoxManage.exe sharedfolder add default --automount --name 'cygdrive/d/gospace' --hostpath '\\?\d:\gospace'
  

  The first command has to be run always. The second needs to be used only when you want to use CygWin instead of default MinGW.
