Let’s see how would you run thumbor in different environments.

Development Environment

For running it locally you just need to get a proper Configuration file. You can put it at /etc/thumbor.conf, ~/thumbor.conf (home folder) or specify it when starting thumbor.

To verify if you have thumbor, just type:

thumbor --version

It should return the version you’ve installed. Starting thumbor is as easy as:

thumbor

For more options check the Configuration page.

Production Environment

Other than having the proper Configuration file for your environment, we have some recommendations on how to run thumbor in production.

Our first recommendation is to run more than one instance of it. You can specify different ports using thumbor easily. This will make sure that your service stays responsive even if one of the processes die.

We also recommend having some form of load balance that distributes the load between the aforementioned processes. We are using NGINX to do it, but there are more sophisticated load balance softwares around. thumbor supports health checking under the /healthcheck URI if you need to use it.

Other than that, you run it using the thumbor console app specifying the arguments, like this:

thumbor --port=8888 --conf="~/mythumbor.conf"

We recommend using an application such as Supervisor (http://supervisord.org/index.html) to monitor your services. An example of a supervisord.conf file would be:

[supervisord]
logfile = /home/thumbor/logs/supervisord.log
logfile_maxbytes = 50MB
logfile_backups=10
loglevel = info
pidfile = /home/thumbor/supervisord.pid
user = thumbor

[program:thumbor]
command=thumbor --port=800%(process_num)s --conf=/etc/thumbor800%(process_num)s.conf
process_name=thumbor800%(process_num)s
numprocs=4
user=thumbor
directory=/home/thumbor/
autostart=true
autorestart=true
startretries=3
stopsignal=TERM
stdout_logfile=/home/thumbor/logs/thumbor800%(process_num)s.stdout.log
stdout_logfile_maxbytes=1MB
stdout_logfile_backups=10
stderr_logfile=/home/thumbor/logs/thumbor800%(process_num)s.stderr.log
stderr_logfile_maxbytes=1MB
stderr_logfile_backups=10

This configuration file makes sure that supervisor starts 4 processes of thumbor on the 8000, 8001, 8002 and 8003 ports, each with a different configuration file (thumbor8000.conf, thumbor8001.conf, thumbor8002.conf, thumbor8003.conf all under /etc folder). The other settings are optional, but if you need help with supervisor’s settings it has extensive documentation online (http://supervisord.org/introduction.html).

Thumbor in the Cloud

Running with Docker
