Permission Denied when trying to enable Docker

[lordofthejars]

Hi I have just installed today the playa-mesos on my computer and it works pretty well, but when I try to enable docker by using echo 'docker,mesos' > /etc/mesos-slave/containerizers, it throws me a Permission denied exception. And the same happens if I use the sudo command. Any idea of what I can do to enable Docker in this case?

Thank you so much.

Hello, sudo doesn't play well with shell redirection. You have too options: 1) Switch to the root user with su and run the command or 2) Run echo 'docker,mesos' > sudo dd of=/etc/mesos-slave/containerizers
