I am trying to set a few sysctl values.Basically the following  sysctl -w \ net.ipv4.tcp_keepalive_time=300 \ net.ipv4.tcp_keepalive_intvl=60 \ net.ipv4.tcp_keepalive_probes=9   in a docker container.When log into to the container directly and execute the command, I get the following error sysctl: cannot stat /proc/sys/net/ipv4/tcp_keepalive_time: No such file or directory sysctl: cannot stat /proc/sys/net/ipv4/tcp_keepalive_intvl: No such file or directory sysctl: cannot stat /proc/sys/net/ipv4/tcp_keepalive_probes: No such file or directory   Then I found out the --sysctl option in docker run in (https://docs.docker.com/engine/reference/commandline/run/) here But I did not find the equivalent option via docker-compose. 
I have few services that start by default so using docker run instead of docker-compose is not an option for me. Anyone knows of a way to supply --sysctl options to the container via compose?

This option is now available in docker-compose 1.10.0-rc1, you'll need to upgrade to that version (pip install docker-compose==1.10.0-rc1 ) and also update your docker-compose.yml file to version 2.1 per (https://docs.docker.com/compose/compose-file/#/version-21) docs  Example docker-compose.yml: version: '2.1' services: app: build: . sysctls: - net.ipv6.conf.all.disable_ipv6=1     (/a/41496841) (Short permalink to this answer) Share  Share a link to this answer     Copy link (https://creativecommons.org/licenses/by-sa/3.0/) (The current license for this post: CC BY-SA 3.0) CC BY-SA 3.0     (/posts/41496841/edit) () Improve this answer  Follow (70:3:31e,16:7accd644d7656a7d,10:1742105951,16:ca9d9e0d5e414faf,8:41496841,8fc71799f784b198ab512eaffe5e74ec712766f47f2d4196e11c3a63aab6b74f)  Follow this answer to receive notifications       answered (2017-01-06 00:01:57Z) Jan 6, 2017 at 0:01   (/users/3006145/d3ming) (d3ming's user avatar)    (/users/3006145/d3ming) d3ming d3ming (reputation score) 9,080 (7 gold badges)  7  7 gold badges (34 silver badges)  34  34 silver badges (34 bronze badges)  34  34 bronze badges        2 (number of 'useful comment' votes received) 1   This is great, but it doesn't seem possible to specify it for builds...

In general, you have to head over to the (https://github.com/docker/compose/issues) github issues for compose and search there. In the case of sysctl , it's in the process of being added. Someone has (https://github.com/docker/compose/issues/3765) made a branch with the addition . You could start with that until it gets added to the master branch.
