Set open FD limits
Not setting these means Docker containers will inherit whatever is set in the Docker dameon, which can vary from env to env.
These values can have a very high cap and have caused problems with memory allocations in #65 (closed)
I verified this fix via:
Set high limits for dockerd
:
cat /etc/docker/daemon.json
{
"default-ulimits": {
"nofile": {
"Hard": 1041312256,
"Name": "nofile",
"Soft": 1041312256
}
}
}
Run a Rails console then:
$ make shell
cat /proc/64/limits | grep 'open files'
Max open files 1024 64000 files

Closes #65 (closed)
