AWS에서 docker를 쓸 때 high traffic server라면 이렇게 하는 것이 좋겠다. amazon linux를 쓴다고 하자.

ulimit

ulimit를 올려주어야 한다. /etc/security/limit.conf 에서 고쳐주어도 docker에는 적용되지 않는다. limit.conf는 PAM을 통해서 로그인했을 때만 먹는 설정이라 그렇다. docker로 띄운 process의 pid를 찾고 cat /proc/<pid>/limits를 실행해서 보면 적용되었는지 아닌지 확실하게 알 수 있다. kernel에서 직접 그 프로세스에 어떤 ulimit이 적용되었는지 확인하는 방법이다.

그래서 /etc/sysconfig/docker 파일을 만들고 아래를 추가한다.

I've been playing with jq, and I've been having a hard time finding examples of how it works with output from a service like AWS (which I use a lot).

Here is one I use a lot with vagrant-ec2.

When we're launching and killing a lot of instances, the AWS API is the only way to track down which instances are live, ready, dead, etc.

To find instances that are tagged with e.g. {"Key" = "Name", "Value" = "Web-00'} in the middle of a vagrant dev cycle, or a prod launch/replace cycle, you can do something like this:

## Allows for creation of "Basic" DNS records in a Route53 hosted zone

function main() {
	record_name=$1
	record_value=$2

	[[ -z $record_name  ]] && echo "record_name is: $record_name" && exit 1
	[[ -z $record_value ]] && echo "record_value is: $record_value" && exit 1
