nodered | An extensible network service container for Node.js | Runtime Evironment library

Use-case: copy a file containing some creds from local machine directory to existing and already created Docker container/volume

Per the documentation on using docker cp, I constructed my command line statement like this:

docker cp mynodered:/Users//Documents/nodered-volume/creds.json /data/creds.json

However, I consistently get an error returned: invalid output path: directory "/data" does not exist

We are trying to push a Docker image based on NodeRED to Heroku. Local build and test runs like a charm, but when we deploy it to Heroku, the Docker image build fails. Our docker file is quite simple:

I am trying to deploy a simple node-red application to my k3s container. Background I have two pi 4's as my server and 3B+ as my workers.

For errors i get

I try to convert the time to STRING in nodered and I always get the result one hour higher. How do I do it right?

Thanks for helping with this issue!

i need deploy to fargate, but nodered rebuild will follow hostname to create flow.json, this make me so hard to load old config to new nodered. But now, if using docker run -h is work,but in fargate dose not work, how can i do?

Of course, release nodered docker version is solved this problem,but i don’t know how to call cli tools,if base on node-red, how can i install aws-cli2 and call it in nodered dashboard?

My client wants to have an OPs Engineer run the Node Red side of the house, but all operations support staff are to use a Single Page App (And never ever touch Node Red), so Part of me was thinking that a sample uibuilder page will create a socket, but if i have an angular app exist and that socket too exists, I can get all the data I need without hacking together code. As they keep extending the use cases, the ui builder is switching from simple screen components to lists, forms, loaders, etc in 1 endpoint, with layer, lots of inline classes, and no organization.

I have a sample UiBuilder for NodeRed called "launch" which when working through some samples has a socket I can listen to. I thought that it would be useful if i could create a different app, which also listens to this socket. For every Message recieved, if it doesnt exist in a list, it will add it to the list and hen from there we will start user stories.

I figured to implement socket in an Angular App, through a service I created. I created a simple client-server relationship with some demos found online, but I am now trying to link it to the Node Red uibuilder launch which exists.

I thought it was going to be as simple as updating the url or path but that seems to not work.

Here is a sample file I was working with:

I have the attach debug output from nodered modbus node and i need to send just the data value in the array to mqtt. How do i achieve this with function node?

I am attaching what i have tried and the debug error, instead of it sending the value to mqtt that is not happening. I am a newbie to this so will appreciate your suggestions. Instead it sending value 36(which is the value of pv1 at the time i took the second screenshot) its returning 0

I'm trying to establish a connection with my mosquitto server through an ESP01 8266. I installed mosquitto on my computer and started it with brew.

The problem is that the ESP01 doesn't connect to the "localhost:1833" (that should be my mosquitto address). I dont' know what to do, am I missing something?

This line could be the problem? I didn't set a client name on NodeRed -------> if (mqttClient.connect("ESP8266Client"))

I use this command in windows I actually don't know where node_red_data is.
