The Maker Faire workshop was a lot of fun, and many lessons were learned!
On the plus side, I think that all of the robots went home able to dispense liquids. Yay!
I am working on some tweaks, improvements, patches, and bug fixes. I will be uploading a new SD card image, and instructions to write it to your SD card. Or I can send you a new SD card — email me at Rich.Gibson at gmail.com if you would like to swap out your SD card.
Configuration Fixes
The initial “big changes” to get the Bartendro admin mode to work is to change your /etc/hosts file:
127.0.0.1 localhost
::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
127.0.0.1 hellodrinkbot
And update /etc/nginx/sites-available/bartendro.conf:
upstream hellodrinkbot {
server 127.0.0.1:8080;
}
# Listen on all interfaces of eth0
server {
root /usr/share/nginx/www;
server_name hellodrinkbot;
access_log /var/log/nginx/bartendro-combined.log combined;
error_log /var/log/nginx/bartendro-error.log notice;
location / {
proxy_pass http://hellodrinkbot;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
# For first-time setup via IP address:
proxy_set_header Host $server_addr;
# If you have custom DNS, use this instead:
# proxy_set_header Host "bartendro.example.com";
proxy_redirect off;
}
}
# Listen on the Bartendro private wifi and redirect all traffic
server {
listen 10.0.0.1:80;
root /usr/share/nginx/www;
server_name hellodrinkbot;
access_log /var/log/nginx/bartendro-combined.log combined;
error_log /var/log/nginx/bartendro-error.log notice;
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location / {
proxy_pass http://hellodrinkbot;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host "hellodrinkbot";
proxy_redirect off;
}
}
server {
listen 10.0.0.1:80 default_server;
server_name _;
rewrite ^ http://hellodrinkbot? redirect;
}
This is a bit of a kludge — I am tweaking a sample conf file and I’m pretty sure there are better ways to do this. Please let me know if you have a better version!
