docker-compose ps enhancements

[dnephin]

This issue is to aggregate all the requests for enhancements to ps.

• include the swarm node name ([Feature Request] docker-compose ps should show swarm node name #2366)
• some way to disable wrapping of lines, either with a flag, or default to no wrapping when the terminal is not a tty (docker-compose ps suggestions #1414)
• machine readable output, as json (Ps output in json #1992)
• container ip address (Add container IP address to "docker-compose ps" output #1038)
• include the short container id (docker-compose ps suggestions #1414)
• support additional fields (docker-compose ps suggestions #1414)

We need to find a way to support all of this without making the default unnecessarily verbose. I think we should be keeping the default fairly close to what we have now.

One option is to add a bunch of flags to include new columns.

Hello,

Thanks to gather the PRs and issues around PS.
I think the default should be as it is, but give an oportunity the user to customize the columns would be great. E.g.: docker ps:

Name Command State Ports

dockermaster_etcd_1 /etcd Up 0.0.0.0:2379->2379/tcp, 2380/tcp, 4001/tcp, 7001/tcp
dockermaster_etcd_2 /etcd Up 0.0.0.0:2380->2379/tcp, 2380/tcp, 4001/tcp, 7001/tcp

docker ps --columns name
dockermaster_etcd_1
dockermaster_etcd_2

And docker ps --help should show the available columns. And ps shouldn't rely on tty at all IMHO, cause for example when user process the output from script there's no such a thing like tty.
The "machine readable output, as json" would be also great. With --json should drop the ps output like a simple json array as you suggested the original PR.

I wanted to bring up another notice. Currently ps returns container name as a first column

# docker-compose ps
     Name                    Command                State     Ports 
-------------------------------------------------------------------
fusion114_cli_1   /opt/startup.sh /bin/sh -c ...   Exit 137         
fusion114_db_1    /entrypoint.sh mysqld            Exit 128         
fusion114_web_1   /opt/startup.sh apache2 -D ...   Exit 0   

However that value is useless for any other docker-compose command as docker-compose can not work with container names but only works with services.

# docker-compose ps fusion114_cli_1
No such service: fusion114_cli_1

# docker-compose ps cli
     Name                    Command                State     Ports 
-------------------------------------------------------------------
fusion114_cli_1   /opt/startup.sh /bin/sh -c ...   Exit 137   

It makes sense to drop Name column and introduce Service Name or Service column instead.

# docker-compose ps
Service                    Command                State     Ports 
-------------------------------------------------------------------
cli         /opt/startup.sh /bin/sh -c ...   Exit 137         
db          /entrypoint.sh mysqld            Exit 128         
web         /opt/startup.sh apache2 -D ...   Exit 0

especially a docker-compose --columns "name, state" will be very intresting for me. I'm running some containers that have a lot of ports (hardware/mailserver for example) and I just want to check if everything is up but it's hard to follow the lines when some containers have more than one line..

[znerd]

Feature parity, and output format parity, across docker ps and docker-compose ps would be very nice.

E.g.:

• docker ps supports filtering (with the -f/-filter option), while docker-compose ps does not
• docker ps supports formatting (with the --format option), while docker-compose ps does not
• docker-ps just returns one line with column names and then the info, while docker-compose ps includes a horizontal line in the output
• etc.

@achekulaev Only if you want to docker cp you'll need the container name.
