SELinux: Could not open policy file

[YiannisGkoufas]

Hi there,

I am using RHEL 7 and the mesos-master works fine. However when I launch the mesos-slave I get the error:

SELinux: Could not open policy file <= /etc/selinux/targeted/policy/policy.30: No such file or directory Failed to create a containerizer: Could not create DockerContainerizer: Failed to create docker: Failed to get docker version: Failed to execute 'docker -H unix:///var/run/docker.sock --version': exited with status 127

Can someone please give me a hint on what's wrong? I started trying different versions of the images and the only one working was the first one (0.19.1)

Thanks a lot!

Hey Yiannis, Did you solve this issue?

[YiannisGkoufas]

Hi there,

no I haven't managed to solve it :(

Thanks!

Hi @YiannisGkoufas! Thanks for filing this issue. Would you mind testing again? I'm hoping that your issue is solved by https://github.com/mesosphere/docker-containers/commit/60ad15cc3471dca33ed2734167ba704395a73fae

@greggomann It seems to work for me. I no longer get the SELinux error.

@greggomann this doesn't work for me on a CoreOS host

• though I was building version 0.28.1-2.0.20.ubuntu1404 rather than 0.20.1-1.0.ubuntu1404 which is the example in the makefile

[greggomann]

@PHPCEO thanks for the report! I've tested with 0.28.x releases in Ubuntu environments, so something must be going on in CoreOS. Are you getting the same SELinux error shown above? Could you provide a little more info on your environment? I'll try some testing on CoreOS tomorrow. Thx!!

[greggomann]

@PHPCEO how exactly were you attempting to build on CoreOS? You were building in a container I imagine? I need a bit more information about your environment in order to reproduce.

[PHPCEO]

@greggomann so sorry for the delay and thank you for the prompt response! I was building on CoreOS running in xhyve on my work laptop, which is running OSX 10.11.6. I tried disabling selinux in the guest OS to no avail. I believe I did get it running, though. I'll add more info later today!

[PHPCEO]

Ok, so I was just running make images , e.g.: make images VERSION=0.28.1-2.0.20.ubuntu1404

When I tried to run the slave image, I get this error:

What I ultimately wound up doing was modifying the Dockerfile such that we install selinux and systemd on the 14.04 image. I also found that I needed to launch the slave omitting the link from /usr/local/bin/docker to /usr/local/bin/docker and with the flag --launcher=posix, which worked :).
