Python version of the "docker ps" command that rearranges the output to fit on a smaller terminal window a little better.

dockerps

#! /usr/bin/env python
# -*- coding: utf-8 -*-
from docker import Client
import sys

reload(sys)
sys.setdefaultencoding('utf8')

c = Client(base_url='unix://var/run/docker.sock')

try:
  if sys.argv[1] == "-a":
    ps = c.containers(False, True)
  else:
    ps = c.containers()

except:
  ps = c.containers()


row = [['NAME', 'IMAGE', 'STATUS', '', '']]
for item in ps:
  container = []
  container.append(item['Names'][0].split('/')[1]+"  ")
  container.append(item['Image']+"  ")
  container.append(item['Status']+"  ")
  portList = ""
  for ports in item['Ports']:
    try:
      if len(portList) == 0:
        portList = portList + str(ports['PublicPort'])+":"+str(ports['PrivatePort'])+"/"+str(ports['Type'])
      else:
        portList = portList + ","+str(ports['PublicPort'])+":"+str(ports['PrivatePort'])+"/"+str(ports['Type'])

    except:
      try:
        if len(portList) == 0:
          portList = portList + ":"+str(ports['PublicPort'])+"/"+str(ports['Type'])
        else:
          portList = portList + ",:"+str(ports['PublicPort'])+"/"+str(ports['Type'])

      except:
        try:
          if len(portList) == 0:
            portList = portList + ":"+str(ports['PrivatePort'])+"/"+str(ports['Type'])
          else:
            portList = portList + ",:"+str(ports['PrivatePort'])+"/"+str(ports['Type'])

        except:
          portList = " "

  if portList != " " or "" :
    container.append("\n\t\t\t└─ "+portList)

  container.append("\n\t\t\t└─ "+item['Command']+"\n")
  row.append(container)
  
widths = [max(map(len, col)) for col in zip(*row)]
for line in row:
  print "".join((val.ljust(width) for val, width in zip(line, widths)))

This is a really handy script. Especially when combined with something like boto3 if looking to get docker status from a range AWS hosts.

One suggestion to make this script backwards-compatible with the newest docker api (2.0+) is to use docker.APIClient instead of Client.

import docker
.....

c = docker.APIClient()

Thanks for writing this up.
