Let'S Encrypt And Google Auth

Tested on Ubuntu 16.04 based distro.

Wekan installed with https://github.com/wekan/wekan/wiki/Export-Docker-Mongo-Data

A) Let's Encrypt support, without Google Auth:

1. https://caddyserver.com config Caddyfile:

my.domain.com {
  proxy / localhost:8080
}

2. Depending with what user you use to run Caddy, adding privileges to that user:

sudo setcap cap_net_bind_service=+ep ./caddy

B) Caddy Let's Encrypt => Google Auth only allowed email addresses => Wekan

1. https://caddyserver.com config Caddyfile:

my.domain.com {
  proxy / localhost:7000
}

2. Depending with what user you use to run Caddy, adding privileges to that user:

sudo setcap cap_net_bind_service=+ep ./caddy

3. Adding Google Auth, so only those email addresses can login:

https://www.npmjs.com/package/proxybouncer

4. Create nologin user for proxybouncer:

useradd -M proxybouncer
usermod -L proxyboucer

5. /etc/systemd/system/proxybouncer.service:

[Unit]
Description=Proxybouncer

[Service]
ExecStart=/usr/local/bin/proxybouncer
Restart=always
RestartSec=5                       # Restart service after 10 seconds if node service crashes
StandardOutput=syslog               # Output to syslog
StandardError=syslog                # Output to syslog
SyslogIdentifier=proxybouncer
User=proxybouncer
Group=proxybouncer
Environment=PORT=7000 MY_URL=https://my.domain.com PROXY_TARGET=http://localhost:8080 GOOGLE_CLIENT_ID=... GOOGLE_CLIENT_SECRET=... ALLOWED_EMAILS=.*@domain.com$ COOKIE_SECRET=...

[Install]
WantedBy=multi-user.target

6. Enable proxybouncer service:

sudo systemctl enable proxybouncer
sudo systemclt start proxybouncer

Question: Does this setup imply that everyone will be logged in to Wekan as 'proxybouncer'? Is there a way to pass username from Google via headers, etc.?

Answer: First login to Proxybouncer can limit login domain of G Suite. Second login is using Wekan username and password. There is no integrated login yet for standalone Wekan like there is for https://sandstorm.io
