Description Alex Jia 2016-08-01 03:16:39 UTC

Description of problem:
As a atomic user, which need to switch docker and atomic command to operate a running container, we should have a unified atomic command interface to do this like atomic ps.

For now, Yuqi Zhang have implemented most of functions in the PR https://github.com/projectatomic/atomic/pull/493, but the option '--sys' hasn't been implemented yet, a trello card https://trello.com/c/3THkrLJp/251-3-add-sys-option-to-atomic-ps is used to trace the issue.

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

[cloud-user@atomic-00 ~]$ cat /etc/redhat-release 
Red Hat Enterprise Linux Atomic Host release 7.2

[cloud-user@atomic-00 ~]$ sudo atomic host status

        Commit: 50a33b6f64616bb4975602f16e76c74a74afc5699a94f4a0a0c8fc99ebe20367

atomic-1.10.5-7.el7.x86_64
docker-1.10.3-46.el7.9.x86_64


How reproducible:
always

Steps to Reproduce:
1. atomic ps

Actual results:

[cloud-user@atomic-00 ~]$ sudo atomic ps
/bin/atomic: invalid choice: 'ps' (choose from 'diff', 'help', 'host', 'info', 'install', 'images', 'mount', 'push', 'upload', 'pull', 'scan', 'stop', 'run', 'storage', 'migrate', 'top', 'uninstall', 'unmount', 'umount', 'update', 'version', 'verify')
Try 'atomic --help' for more information.


Expected results:

Support atomic ps command and include '--sys' option

Additional info:


1. w/ --json option, the output json format string in a list, is it an expected result?
$ sudo ./atomic ps --json
[{"status": "running", "container": "725bfa05a8bf8971c5acf656cf14b97c5058bb8d787c6477c7a03234d21d8b2c", "created": "2016-07-27 03:27", "image": "registry.access.redhat.com/rhel7.2", "command": "/bin/sh", "runtime": "Docker", "type": "docker"}]

2. docs issue, please see projectatomic/atomic: Pull Request 501

3. it has a little hard to know how to use --filter option, could you add some examples into atomic-ps docs?

Comment 2 Daniel Walsh 2016-08-19 21:46:42 UTC

Fixed in atomic-1.11

Comment 4 Alex Jia 2016-09-18 04:27:01 UTC

The atomic ps command has been replaced by new atomic containers list command in atomic-1.12.0-1.el7.x86_64, and it works well to list single running container, but failed to list multiple running containers in atomic-1.12.0-1.el7.x86_64, for now, the issue has been fixed in 
 atomic-1.12.2-2.el7.x86_64.

Comment 5 Alex Jia 2016-09-27 22:07:55 UTC

We will get an error like 'ImageId' when the running containers are more than 2, such as 3 running containers.

Comment 7 Daniel Walsh 2016-09-27 22:41:08 UTC

I have opened 
https://github.com/projectatomic/atomic/pull/667

To fix this issue.

Basically this only happens if you have a vulnerable image on your system.

Comment 9 Daniel Walsh 2016-09-28 11:23:54 UTC

This feature was added and will be in RHEL7.3, there is a bug though. atomic containers list works fine, unless you have a container/image on your system which has known vulnerability.

Comment 10 Daniel Walsh 2016-10-18 16:03:08 UTC

Fixed in atomic-1.13

Comment 12 Alex Jia 2016-10-28 08:54:12 UTC

It works well for me.
