openwhisk-composer can't connect to redis server when doing parallel compositions


Any body here tried openwhisk-composer composer.parallel()?

my openwhisk action can't seem to connect to the redis-server ive setup,

when i invoke the action with the composer.parallel() it throws error

const composer = require('openwhisk-composer');

// complexwf.js
module.exports = composer.retain(
    composer.action('step-a', { action: function (params) {
        console.log('log-step-a', params);
        return { value: 'from-step-a' } 
    } }),
    composer.action('step-b', { action: function (params) { 
        console.log('log-step-b', params);
        return { value: 'from-step-b' } 
    } }),
    composer.parallel(
        composer.action('step-c', { action: function (params) { 
            console.log('log-step-c', params);
            return { value: 'from-step-c' } 
        } }),
        composer.action('step-d', { action: function (params) { 
            console.log('log-step-d', params);
            return { value: 'from-step-d' } 
        } }),
    )
);

just a little info on my setup, my redis-server runs on docker have tried connecting to my redis server via the redis explorer in vscode and is working,


Solution

  • was able to make it work, i changed the redis uri in the input to the container ip not the public ip so the input is like this

    {
        "name": "complexwf",
        "params": {
            "$composer": {
                "openwhisk": {
                    "ignore_certs": true
                },
                "redis": {
                    "uri": "redis://172.17.0.2:6379"
                }
            },   
            "value": "from-input" 
        }
    }
