Description Frantisek Kluknavsky 2016-01-19 14:17:08 UTC

+++ This bug was initially created as a clone of Bug #1201663 +++

Description of problem:

Create minimal image which runs systemd(-container) based on rhel7.1, using Dockerfile

   FROM rhel7.1
   RUN yum install -y /usr/bin/ps
   ENV container docker
   CMD [ "/usr/sbin/init" ]

Run a container and inspect running processes -- /usr/bin/rhsmcertd will be there. It's because

   rhsmcertd.service

service is enabled in

   /etc/systemd/system/multi-user.target.wants/rhsmcertd.service

The man rhsmcertd(1) says

        Periodically scans and updates the entitlement certificates on
        a registered system.

but in a container, entitlement certificates are inherited from the
host. It seems this service should be removed from the target.

Version-Release number of selected component (if applicable):

Image rhel7.1
docker-1.5.0-16.el7.x86_64

How reproducible:

Deterministic.

Steps to Reproduce:
1. Have Dockerfile as shown above.
2. Build, run a container.
3. Check the processes running in the container using

   docker exec <the-container-id> ps axuwwf

Actual results:

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
root        70  0.0  0.0  19760  1132 ?        R    04:39   0:00 ps axuwwf
root         1  0.5  0.0  44752  2800 ?        Ss   04:39   0:00 /usr/sbin/init
root        63  0.0  0.0  32144  2640 ?        Ss   04:39   0:00 /usr/lib/systemd/systemd-journald
root        68  0.0  0.0   9740   668 ?        Ss   04:39   0:00 /usr/bin/rhsmcertd
root        69  0.0  0.0   6424   840 ?        Ss   04:39   0:00 /sbin/agetty --noclear --keep-baud console 115200 38400 9600


Expected results:

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
root        70  0.0  0.0  19760  1132 ?        R    04:39   0:00 ps axuwwf
root         1  0.5  0.0  44752  2800 ?        Ss   04:39   0:00 /usr/sbin/init
root        63  0.0  0.0  32144  2640 ?        Ss   04:39   0:00 /usr/lib/systemd/systemd-journald
root        69  0.0  0.0   6424   840 ?        Ss   04:39   0:00 /sbin/agetty --noclear --keep-baud console 115200 38400 9600

Additional info:

This clone will track temporary workaround `rm -f /etc/systemd/system/multi-user.target.wants/rhsmcertd.service` while the original bug report will wait for a proper solution with systemd preset.

Comment 2 Jan Pazdziora 2016-01-19 14:25:20 UTC

How is this bugzilla different from bug 1201663, in purpose and such?

Comment 4 Frantisek Kluknavsky 2016-02-01 13:20:10 UTC

The same bug. One bugzilla is for a short-term not-so-nice solution. Second bugzilla for later when a clean desired solution becomes possible, waiting for https://bugzilla.redhat.com/show_bug.cgi?id=1209382
It is awkward. Could you give me a hint how to properly solve such situations? We want both changes tested by QA.

Comment 6 Martin Jenner 2016-02-11 23:01:19 UTC

Verified /etc/systemd/system/multi-user.target.wants/rhsmcertd.service no longer exists in test image built on registry.access.stage.redhat.com/rhel7.2:7.2-43

From within the built test container I can confirm

 [root@6cd7fa38e3e3 /]# systemctl is-enabled rhsmcertd.service
disabled
