{ name: 'SERVER', value: 'some_prefix' },
{ name: 'NUMBER_OF_TYPES', value: 5 },
{ name: 'PLATFORM', value: 'AZURE' },
],
arguments: [ // arguments that you can get in the container
{ name: '--operation', value: 'getNames' },
{ name: '--id', value: 'mdK23ds' },
{ name: '--version', value: 'published' },
],
command: ['node', 'index.js'], // command to run
};
