This is dockerized version of Live Helper Chat. It includes these images

• web - nginx service
• php - php-fpm service
• cobrowse - cobrowsing running NodeJS service
• php-cronjob - cronjobs running service
• php-resque - php-resque worker running service
• nodejshelper - NodeJS Helper NodeJS running service
• redis - Redis service
• db - Database service

• Checkout the repository

• Run cd docker-standalone

• Copy .env.default to .env

• Edit .env file and change LHC_SECRET_HASH to any random string

• Database default settings if you don't change those in .env file.

  • Host - db
  • Database name - lhc
  • Database username - lhc
  • Database password - lhc

• For version with NodeJS plugin (Recommended)

  • Run install-nodejs.sh this will checkout Live Helper Chat and required extensions
  • Optional. Run docker compose -f docker-compose-nodejs.yml build --no-cache to build from scratch. You might need it you are running on linux/arm64 as I only provide linux/amd64 architecture
  • Run docker compose -f docker-compose-nodejs.yml pull && docker-compose -f docker-compose-nodejs.yml up to use already existingimages

• For standard version without NodeJS plugin run

  • Run install.sh this will checkout Live Helper Chat and required extensions
  • Optional. Run docker compose -f docker-compose-standard.yml build --no-cache to build from scratch. Build is optional. You might need it you are running on linux/arm64 as I only provide linux/amd64 architecture
  • Run docker compose -f docker-compose-standard.yml pull && docker-compose -f docker-compose-standard.yml up

• You will need to install composer dependencies:

  1. Open a shell in the docker container

     docker exec -it --workdir /code docker-standalone-php-1 /bin/bash

  2. Visit https://getcomposer.org/download/ and run the commands to get composer.phar
  3. Run this to actually install the dependencies:

     php composer.phar update
     php composer.phar install

• Edit docker-standalone/lhc-php-resque/lhcphpresque/settings/settings.ini.php and put proper site_address domain value. php-resque does not know what domain it's running

• Make sure the cache, settings and var folders have the correct permissions:

docker exec -it docker-standalone-web-1 chown -R www-data:www-data /code/cache
docker exec -it docker-standalone-web-1 chown -R www-data:www-data /code/settings
docker exec -it docker-standalone-web-1 chown -R www-data:www-data /code/var

• Navigate to localhost:8081 and follow install instructions.
  • db username and password: Check .env file
  • db host: db.
  • db port: 3306
• If you want to run docker as a service append -d to docker commands. docker-compose -f docker-compose-nodejs.yml up -d

Edit .env file and set LHC_PUBLIC_PORT and LHC_NODE_JS_PORT port to 80

That's up to you. You can have in host machine runing nginx and just proxy request or tweak images/docker files I provided. You should play around with web service.

E.g to the ones who are too lazy too use google :D

Generate SSL certificate under docker folder for demo.livehelperchat.com domain. Change paths in this command. You have to be pointed domain to your sever

certbot certonly --config-dir /opt/lhc/docker-standalone/conf/nginx/ssl --webroot --webroot-path /opt/lhc/docker-standalone/livehelperchat/lhc_web -d demo.livehelperchat.com

This is how cronjob can look like. Make sure you put your domain and correct docker-standalone-web-1 name.

0 0 * * * certbot certonly --keep-until-expiring --config-dir /opt/lhc/docker-standalone/conf/nginx/ssl --webroot --webroot-path /opt/lhc/docker-standalone/livehelperchat/lhc_web -d demo.livehelperchat.com --post-hook "docker restart docker-standalone-web-1" > /dev/null 2>&1

If you are migrating server and want to setup fresh certbot, you can just use this command

certbot certonly --manual --preferred-challenges http --config-dir /opt/lhc/docker-standalone/conf/nginx/ssl -d demo.livehelperchat.com

web service part will have to look like

  web:
    image: nginx:latest
    env_file: .env
    ports:
      - "${LHC_PUBLIC_PORT}:80"
      - "443:443"
    volumes:
      - ./livehelperchat/lhc_web:/code
      - ./conf/nginx/site-ssl.conf:/etc/nginx/conf.d/default.conf
      - ./conf/nginx/mime.types:/etc/nginx/mime.types
      - ./conf/nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./conf/nginx/ssl/live/demo.livehelperchat.com/fullchain.pem:/etc/nginx/ssl/demo.livehelperchat.com/fullchain.pem
      - ./conf/nginx/ssl/live/demo.livehelperchat.com/privkey.pem:/etc/nginx/ssl/demo.livehelperchat.com/privkey.pem
    depends_on:
      - db
      - php
      - php-cronjob
    networks:
      - code-network
    restart: always

Modify /conf/nginx/site-ssl.conf and change where you see demo.livehelperchat.com to your domain.

Rebuild docker image after a changes.

cd /opt/lhc/docker-standalone && docker compose -f docker-compose-nodejs.yml build --no-cache

Remember to automated SSL issuing workflow :)

cd /opt/lhc/docker-standalone && docker compose -f docker-compose-nodejs.yml down
cd /opt/lhc/docker-standalone && docker compose -f docker-compose-nodejs.yml up -d

You have to edit back office mail settings and use SMTP.

# Update docker images
cd docker-standalone && git pull origin master
# If there is any changes you can build your containers
docker compose -f docker-compose-nodejs.yml build --no-cache

# Or just pull new ones
docker-compose -f docker-compose-nodejs.yml pull

# I would recommend also just restart composer containers
docker compose -f docker-compose-nodejs.yml down
docker compose -f docker-compose-nodejs.yml up
# OR start docker as service
docker compose -f docker-compose-nodejs.yml up -d

# All these commands are executed from docker-standalone folder
cd livehelperchat && git pull origin master
cd lhc-php-resque && git pull origin master
cd NodeJS-Helper && git pull origin master

# Login to php-fpm container and execute
docker exec -it docker-standalone-php-1 /bin/bash
# Execute in container. You might need to download composer.phar file
cd /code && php composer.phar update
cd /code && php composer.phar install
cd /code && php cron.php -s site_admin -c cron/util/update_database -p local
cd /code && php cron.php -s site_admin -c cron/util/clear_cache

• Go to Settings -> Live help confgiuration -> Chat configuration -> Screen sharing and

• Set 'site_address' => 'https://chat.example.com' in settings/settings.ini.php to your install installation path. It has to be location where index.php is located.
• Set site_address in docker-standalone/lhc-php-resque/lhcphpresque/settings/settings.ini.php
• After install make sure settings/settings.ini.php file looks like this if you are using php-resque and nodejs

• array (
  0 => 'lhcphpresque',
  1 => 'nodejshelper',
  ),```
