docker-ps-parser

Parses the output from docker ps into an object

Install

npm install docker-ps-parser --save

Usage

var Parser = require("docker-ps-parser");
 
var psOutput = fs.readFileSync(__dirname + "/output.txt").toString();
 
var parsed = Parser.parse(psOutput);

The code above reads a file that contains the output of a docker ps command. For example:

CONTAINER ID        IMAGE                COMMAND                  CREATED             STATUS              PORTS               NAMES
000000000001        fileserver:1027      "/bin/entrypoint node"   2 hours ago         Up 2 hours                              fileserver5
000000000002        fileserver:1027      "/bin/entrypoint node"   2 hours ago         Up 2 hours                              fileserver4
000000000003        fileserver:1027      "/bin/entrypoint node"   2 hours ago         Up 2 hours                              fileserver3
000000000004        fileserver:1027      "/bin/entrypoint node"   2 hours ago         Up 2 hours                              fileserver2
000000000005        fileserver:1027      "/bin/entrypoint node"   2 hours ago         Up 2 hours                              fileserver1
000000000006        varnish:1009         "/start"                 2 weeks ago         Up 2 weeks                              varnish

This would output:
