Node-Red Docker container won't restart after adding a node

I'm hoping that someone can help me, perhaps someone who uses Docker has had the same problem.

I was playing about adding a Node for IFTTT, and left a port for '80' in the config. Since doing this, the Container crashed and I cannot restart the Container. Is there a way to recover from this?

I get the following log....

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.

I am not up to speed on docker but if you can add a startup parammeter you could add --safe to start up node-red in safe mode.

alternatively if you can access the file system, you could rename the xxx_flow.json file and restart - this way node-red wont load and run your flow.

Hi Steve, thanks for the reply - I didn't realise I had one!
I managed to find where the docker files where, I got it working again by deleting the ‘.flows.json’ file and renaming the ‘.flows.json.backup’ to ‘.flows.json'.
