node-cron fails in docker-compose

[thebetterjort]

I have dockertized this script to fire off every X seconds, which goes and grabs some data from an employee page and serves it out over rest. Problem is -- I can't get it to run in a docker container, but I can if i just node server.js --

Any ideas?

// ```
const express = require('express');
// const expressGraphQL = require('express-graphql');
// const schema = require('./schema/schema');
// const bodyParser = require('body-parser');
var CronJob = require('cron').CronJob;
var Nightmare = require('nightmare');
require('nightmare-inline-download')(Nightmare);
var fs = require('fs');
var nightmare = Nightmare({
switches: {
'ignore-certificate-errors': true,
'show': true
}
});
//libs for json conversion
xml2js = require('xml2js');
var util = require('util')
var path = require('path');
// const app = express();

// app.use('/graphql', expressGraphQL({
// schema,
// graphiql: true
// }));
// app.use(bodyParser.json());
// app.listen(4000 || process.env.port, () => {
// console.log('Listening');

// });

const STATE = process.env.state || "AR";
const TIME = process.env.time || 1 * 10000;
console.log('STATE: ' + STATE);
console.log('TIME: ' + TIME);







var job1 = new CronJob({
  cronTime: '0 */2 * * * *',
  onTick: function() {
    console.log('job 1 ticked');

      var savejson = __dirname + '/latest.json';
      var options = {
          object: false,

+1 @thebetterjort did you find any ans regarding this..?

[ncb000gt]

I haven't tried to run any cron jobs with this through docker containers. Have you been able to find anything out related to this? This module uses node timers to function. It does also function using child_process but unless you're using a modified version of node, that should work in your container and not a problem, presumably. I might be doing some things with node and cron and containers so if I see something related then I'll see what I can figure out. Otherwise, I'm probably going to close this due to age and inactivity.
