Hi there,

when I try to generate a new github ssh key in node red, running in a docker container, based on alpine, on a arm32v7 base image,  
Nodered throws this error.

can be repeated doing this:  
docker run -d -p1880:1880 --name nodered echteler/nodered:balluff\_arm\_dev  
when the prompt tells you to generate a new ssh key to clone a repo, NR crashes with those logs:

```auto

---------------------------------------------------------------------
Your flow credentials file is encrypted using a system-generated key.

If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.

You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

You need to make sure the `ssh-keygen` command is installed in your docker image for this to work.

Node-RED should also handle this better and not crash fatally. If you can raise as issue [here](https://github.com/node-red/node-red), we can address that part of it.

Hi Nick,

thank you for your fast answer.  
indeed, i missed to add ssh-keygen to the base image.  
already fixed it 🙂

I'll also raise the issue quickly 🙂
