when I pull the debian:stretch-slim from hub.docker.com, and then run a container(root), I find that bash: sysctl: command not found.
How can I use sysctl in debian:stretch-slim?
and many images are builded from debian:stretch-slim, so when I want to use sysctl in some other containers like that:
docker run --rm -it redis:latest --sysctl net.core.somaxconn=2048 redis-server
It will throw ERROR message.
It can be tested like:
docker pull debian:stretch-slim
docker run --rm -it debian:stretch-slim bash
root@7b923f27f7ee:/# sysctl
bash: sysctl: command not found
Start your container with this command:
docker run --rm -it --sysctl net.core.somaxconn=2048 redis:latest redis-server
--sysctl should be docker run's argument and it should not be a command to your redis image
