Bug ID: 1088259
           Summary: "docker top all" doesn't show processes when
                    --tty=false
           Product: Fedora
           Version: 20
         Component: docker-io
          Assignee: [e-mail]
          Reporter: [e-mail]
        QA Contact: [e-mail]

Description of problem:
Hi guys, when I run docker with --tty=false, the `docker top $NAME all` doesn't
show any processes (just headers). When using only `docker top $NAME` it shows
them...

Also the `ps` command inside container works, but `ps all` does not.

Version-Release number of selected component (if applicable):
docker-io-0.9.0-3.fc20.x86_64

How reproducible:
always

Steps to Reproduce:
1. docker run -i --tty=false fedora bash
2. docker logs $NAME

Actual results:
F                   UID                 PID                 PPID               
PRI                 NI                  VSZ                 RSS                
WCHAN               STAT                TTY                 TIME               
COMMAND

Expected results:
F                   UID                 PID                 PPID

WCHAN               STAT                TTY                 TIME

Can't reproduce with the upstream Docker version 0.10.0, build dc9c28f/0.10.0
top doesn't work at all (due of

OK I moved it to the old cgroup location and the results are the same. So
booth, fedora docker-io-0.9.0-3.fc20.x86_64 and upstream dc9c28f/0.10.0 are
unable to list processes using `all` argument in non-tty mode.

build.

I'm sorry there is a typo in reproducer:

Steps to Reproduce:
1. docker run -i --tty=false fedora bash
2. docker top $NAME all

The all is important and it generates the same results with
docker-0.11.1-6.el7.x86_64 (so no processes listed when "docker top $NAME all"
is used, it works fine with "docker top $NAME" and "docker top $NAME -x").

btw using "docker run -i --tty=false fedora sleep 1000 &" leads to the same
problem mentioned here:

https://bugzilla.redhat.com/show_bug.cgi?id=1096273

only it's repeating TTIN signals until I reattach it.

I am not familiar with all,  I guess this is just the same as ps al, all

Hi Daniel, I probably didn't emphasize the `--tty=False` enough. The problem
is, that with `--tty=true` these commands works fine (the only requirement is
keep headers and have PID in it).

RHEL version seems to be fixed now (
https://bugzilla.redhat.com/show_bug.cgi?id=1096286 ), but fedora's
docker-io-0.11.1-7.fc20.x86_64 still has this (and the cgroup path) problem.

Hi Daniel, today I retested this on the latest docker-io-1.0.0-6.fc20.x86_64
and docker-1.0.0-10.el7.x86_64, booth are failing again:

# TERM1
docker run -i --tty=false fedora bash
sleep 1000

# TERM2

as you can see with `docker top ... all` no processes are shown, only headers.
When `tty=true` it works fine.

--- Comment #12 from Lukas Doktor  ---
^^ the last message is maybe a bit confusing. On the output you can see, that
`docker top $id all` doesn't show any processes while `docker top $id` does.

The other sentence about `tty=true` is not visible from the output, but I
verified it works in different run...

Hi Dan, I moved back to qemu, Chris, could you please verify that `docker top

all processes correctly)

Dan,

This issue still reproduces in both docker-1.4.1-37.el7.x86_64 and
docker-1.5.0-16.el7.x86_64 with and without --tty (as described above).

--- Comment #19 from Fedora End Of Life  ---
This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '20'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 20 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Docker top shares options with ps, not docker ps.
(See man ps)
To list all processes, type `docker top $id -A` per man ps
