Discourse BBS System(1)Discourse System Standalone Mode

Follow the document install on Virtual Box first
Switch to root user
> sudo -s

Generate the directory
> mkdir /var/discourse

Clone and get the latest codes
> git clone https://github.com/discourse/discourse_docker.git /var/discourse

Go to working directory
> cd /var/discourse/

Run the install command it will fails because my 80 port is taken
> ./discourse-setup
Port 80 appears to already be in use.
This will show you what command is using port 80
COMMAND  PID     USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
apache2 1296     root    4u  IPv6  19934      0t0  TCP *:http (LISTEN)
apache2 1297 www-data    4u  IPv6  19934      0t0  TCP *:http (LISTEN)
apache2 1298 www-data    4u  IPv6  19934      0t0  TCP *:http (LISTEN

Maybe need to change port
https://meta.discourse.org/t/running-other-websites-on-the-same-machine-as-discourse/17247

Stop the container
> ./launcher stop app

Actually, I may not need to stop the app because it does not runs on my machine because of 80 port
> cp samples/standalone.yml containers/app.yml

Edit that file
> vi containers/app.yml
expose:
  - "8080:80"  # http
  - "8443:443" # https

Rebuild and run
> ./launcher rebuild app

Actually I should run this
> ./discourse-setup

Configure the Email
Hostname      : ubuntu-master
Email         : [e-mail]
SMTP address  : smtp.gmail.com
SMTP port     : 465
SMTP username : [e-mail]
SMTP password : xxxxxx

Yeah, I can start from there
http://ubuntu-master:8080/

Command to stop and start
>./launcher stop app
>./launcher start app

But I did not received the email even I setup gmail accounts.
You need to go to your gmail.  Click on ‘Account’ —> “Sign-in & security” —> Apps with account access —> “Allow less secure apps: ON"

You may need to check your security alert emails to confirm you are the one who attempt to login as well.

It seems configuration with sendgrid works
  DISCOURSE_SMTP_ADDRESS: smtp.sendgrid.net
  DISCOURSE_SMTP_PORT: 587
  DISCOURSE_SMTP_USER_NAME: username
  DISCOURSE_SMTP_PASSWORD: xxxxxx
  DISCOURSE_SMTP_ENABLE_START_TLS: true

For discourse, we should use PORT 587 for gmail as well.

All the files are stored here I think
/var/discourse

It will not work on RaspberryPI
./launcher rebuild app
ERROR: Docker version 1.10.3 not supported, please upgrade to at least 17.03.1, or recommended 17.06.2
