Has the option to use NODE\_RED\_USERNAME and NODE\_RED\_PASSWORD to set an admin login for the editor been removed? It works in NR 1.x, but apparently not in NR 2.x.

Thanks

Hi @hammoaj

those env vars are specific to the wrapper used when running Node-RED in IBM Cloud. It isn't a core feature.

As far as I can see, the code is still there to use them - [node-red-app/index.js at master · IBM/node-red-app · GitHub](https://github.com/IBM/node-red-app/blob/master/index.js#L36)

Thanks @knolleary

Am I right in thinking that I read that you can use environment variables to override individual options in the settings file? If so, could you point me at the documentation?

The IBM-specific env vars are listed here: [GitHub - IBM/node-red-app: Node-RED application that can be deployed into IBM Cloud with a few clicks](https://github.com/ibm/node-red-app#environment-variables)

Hi Nick - that wasn't a question re IBM. More specifically it was a question as to whether I can set an environment variable when I run a docker container versus having to update the settings file.

For example if I want to override `httpAdminRoot` is there a way of doing it with a environment variable?

The only env vars the core supports are:

- `NODE_RED_HOME` - to set the userDir (same as the `-u` command line option)
- `NODE_RED_ENABLE_SAFE_MODE` - to start in safe mode (same as `--safe` option)
- `NODE_RED_ENABLE_PROJECTS` - to enable the projects feature
- `NODE_RED_ENABLE_TOURS` - to enable/disable the new welcome tour feature

Perhaps you edited settings.js to use the env var.

I did precisely that!!

Can the -D option when you call mode-red also be used to do this?

Well `node-red -h` suggests that you can. Have you tried?
