Change fs.protected_hardlinks on Ubuntu docker container

I'm very new to docker but I'm trying to change that setting and the usual ways aren't working.

The settings is fs.protected_hardlinks to 1

I've tried changing /etc/sysctl.d files as well as the /etc/sysctl.conf

Solution

  • Alright everyone, i just learned a SH*T load about docker I never wanted to know but long story short here is how I got greengrass working on a docker container.

    first launch docker toolbox, once its up I used virtualbox manager to log in and the running instance called "default" is the instance of docker server.

    Logged into that and ran these 4 commands (btw I haven't figured out how to persist this so when someone does feel free to add that as a comment)

    sudo su
echo "fs.protected_hardlinks = 1" >> /etc/sysctl.conf
echo "fs.protected_symlinks = 1" >> /etc/sysctl.conf
sysctl --system
