Is it possible to add flags by default to Docker run

Question

I'd like to know if it's possible to configure the docker engine to always add a custom flag (--sysctl) for all containers?

My problem is that I'am a rancher user, and rancher doesn't support the --sysctl flag. I'am looking for a workarround to this.

Thank you.

Try updating the `DOCKER_OPTS` line in `/etc/default/docker`, adding what you want. Restart docker daemon. — Webert Lima, Jan 31 '17 at 18:16

From rancher-version - v1.2.0-pre4-rc4 sysctl option is supported. Add appropriate option in launchconfig:

"launchConfig": {
"type": "launchConfig",
"sysctl": <options-here>
}

The launchConfig property is only accessible via the rancher API isn't it? – Cabrinha Feb 03 '17 at 07:41
