node-deploy-monitor

Objectives & Capabilities

Build a Docker Image from a given Dockerfile and an application (a simple ‘Hello world’ web app would be fine)
Start a few instances of the Docker Image in different containers
Validate that the container instances are running
Monitor the resource usage of each container (CPU, I/O, etc)
Consolidate the log output of all the container instances into one centralized log file.
(extra) Kill all running/stopped processes of a Docker Image

For CLI to work, you need to install a couple of deps using yarn install in the root directory. Then just execute node cli.js to get started.

build test1 ./sample/Dockerfile ./sample

run test1 --instances 2 # Docker on Mac struggles for minutes if I put more than 5, so I put a limit. Also, instances is optional, default is 1.

validate test1

monitor test1

logs test1

kill test1 # This will kill all instances

To get the GUI up, you need to install some extra deps:

cd to gui directory
Run yarn install
Run yarn start to get it up an running (visit http://localhost:3000 if it doesn't open automatically)

The GUI is only able to show and kill containers, so make sure you start some first from the CLI!
