sysctl-write-docker

Write kernel parameters using sysctl with Docker.

Usage

The input to the tool is the environment variable SYSCTL, which is just a JSON mapping of kernel parameters to values.

docker run --privileged -e 'SYSCTL={"fs.aio-max-nr":"500000"}' quay.io/dollarshaveclub/sysctl-write-docker:latest

Block

Use the SYSCTL_BLOCK=true environment variable to have the command block indefinitely.
