Image not running using capstan

[Shambo Bose]

Hi All,

I am trying to build one package with a simple nodejs app. I already built the image and seems like it is running fine without any errors but I don't see any running instances nor any service is listening on the port 3000. Please find screenshots below:

ubuntu@unikern:~/calc$ cat meta/package.yaml
name: calculator.app.pkg
title: Calculator App
author: Shambo
created: "2022-04-27T19:05:46Z"
require:
  - osv.node-js
ubuntu@unikern:~/calc$ cat meta/run.yaml
runtime: native
config_set:
   ################################################################
   ### This is one configuration set (feel free to rename it).  ###
   ################################################################
   default:
      # REQUIRED
      # Filepath of the NodeJS entrypoint (where server is defined).
      # Note that package root will correspond to filesystem root (/) in OSv image.
      # Example value: /libnode.so server.js
      bootcmd: /libnode.so server.js
      # OPTIONAL
      # Environment variables.
      # A map of environment variables to be set when unikernel is run.
      # Example value:  env:
      #         PORT: 3000
      #         HOSTNAME: www.myserver.org

      #env:
      #   PORT: 3000

# Add as many named configurations as you need

# OPTIONAL
# What config_set should be used as default.
# This value can be overwritten with --runconfig argument.
config_set_default: default

Hi,

Which version of capstan are you using? Most likely you have to pass '-f' option to expose the port your app is listening to host like in this example:

capstan run com.example.word-finder -f 4004:4000

from https://github.com/cloudius-systems/capstan/blob/master/Documentation/WalkthroughNodeJS.md.

Regards,

Hi,

capstan version v0.5.0

Command I am running is :

#  capstan run com.calculator.app.pkg. -f 3000:3000

This is an app running on node v8.
