How to access the Node-Red Settings file when running Node-Red Docker Container in an Azure Container Instance

Question

I have deployed Node-Red to an Azure Container Instance using the standard Node-Red image found at Docker Hub.

I would like to secure:

1. access to the editor
2. access to existing HTTP In nodes, used to create a simple API end-point

I am considering to deploy the Container Instance to a Azure Private Network with its own Network Security Group but I am not sure that will actually do the trick.

When reading up on how to secure Node-Red, it is dependent on settings on the Settings.json file.

But how do I even access and update that when running it as a Container Instance?

I am able to connect to the container file system using the Connect option for the Container Instance, but there seem to be no Settings file. Or at least it is not shown.

So:

1. is it even possible to modify the Settings.json file when running a Container Instance?
2. if so, how do I access it?
3. how do I update it and reload Node-Red using it?

Answer 1

From the container logs, you will see the path of settings file is /usr/src/node-red/node_modules/node-red/settings.js

To access the setting file, you can navigate to Container instances---Containers--- Connect---/bin/bash. Navigate to that path, you will find the settings.js file. Then you can use vim to edit it.

Update the containers in a running container group by redeploying an existing group with at least one modified property. When you update containers, please note that not all properties of a container group support updates. To change some properties of a container group, you must first delete, then redeploy the group. See Properties that require container delete.
