My Docker Command

When working with docker toolbox, sometimes I type get tripped up trying to type docker-machine env default and accidentally type docker machine env default instead. This bash script is a helper to allow you to do just that.

Put it in your $PATH and chmod +x my-docker. Then create an alias in your profile with alias docker="my-docker"

Now when you type docker machine env this will automatically proxy anything after machine to docker-machine.

Same goes for docker compose up proxies to docker-compose up.

# ---------- Status Cats Error Pages!!! via: https://http.cat/ ---------
#
# requires that a dns resolver be set for nginx as in: resolver 127.0.0.1;
# typically uses dnsmasq for 127.0.0.1 resolver
#
# Usage: 
# place this file somewhere accessible to nginx. /etc/nginx/snippets is a decent choice.
# then inside the server block(s) you want cat themed error status responses do:
# include snippets/http-cat-error-pages.conf

On Tue Oct 27, 2015, history.state.gov began buckling under load, intermittently issuing 500 errors. Nginx's error log was sprinkled with the following errors:

2015/10/27 21:48:36 [crit] 2475#0: accept4() failed (24: Too many open files)

2015/10/27 21:48:36 [alert] 2475#0: *7163915 socket() failed (24: Too many open files) while connecting to upstream...

An article at http://www.cyberciti.biz/faq/linux-unix-nginx-too-many-open-files/ provided directions that mostly worked. Below are the steps we followed. The steps that diverged from the article's directions are marked with an *.

1. * Instead of using su to run ulimit on the nginx account, use ps aux | grep nginx to locate nginx's process IDs. Then query each process's file handle limits using cat /proc/pid/limits (where pid is the process id retrieved from ps). (Note: sudo may be necessary on your system for the cat command here, depending on your system.)
2. Added fs.file-max = 70000 to /etc/sysctl.conf
