I have used Azure Container Instances to stand-up different Node-Red containers multiple times. It is quickly done and everything seem to go as intended. I can access and deploy Node-Red flows without any problems, set up HTTP In nodes that are publicly available and save some Flow Variables to k…

[image] tobiaspe: Without warning though, at some time, the deployed flows are all deleted, likely because the container restarted and pulled the Node-Red image automatically again. I did some further digging in the azure documentation: Manually stop or start container group - Azure Contain…

Hello @tobiaspe I have noticed similar problems when running node-red in Kubernetes. For me, the problem was that the flow files are postfixed with the hostname, and every time a new container was created the hostname changed. Try setting the flow file to a fixed name in the settings.js and see if …

The two things that you need to do are documented in here already but to emphasise: You should configure a fixed name for the settings.js file (which is the default I think in the docker image) You must configure a persistent storage volume to be mounted on /data otherwise you will indeed lose you…

Hi @tobiaspe , The flows you create/edit are stored under the /data folder. It is important that the /data folder is mounted to a docker volume in order to assure that you don't loose the flows you have edited/created when replacing the docker image with a new docker image version.

Thanks a million for all your replies, they were all very very valuable and I now understand much more on what I need to setup to make my flow persist over a container restart/repull. But a really stupid question. am I to run the CLI and command within the "Connect To" using Bash in my actual Conta…

[image] tobiaspe: But a really stupid question. am I to run the CLI and command within the "Connect To" using Bash in my actual Container Instance? Or do I somehow access the Container Instance container from Docker? How do I run the examples on how to set this up through/to my deployed Node-Red…

Well, I would like to interact with the ACI Container, or rather the underlying Settings file. How do I connect to the underlying files of the Node-Red container. From the Azure Portal I can use Connect and then run bash commands (see screen dump). Is there another way of interacting with underlyin…

[image] tobiaspe: Well, I would like to interact with the ACI Container, or rather the underlying Settings file. Do you want to change the node-red settings file ? I think you can find it at location /data/settings.js If it is it not there then try creating a setting.js in that location. T…

Yes, but where do I do that? Do I access the container from inside the Azure Portal? Using Connect directly under the Azure Container Instance using Bash commands? Where do I run any similar commands and access the Node-Red files?

[image] tobiaspe: Using Connect directly under the Azure Container Instance using Bash commands? Yes, that is a way you can do it. I guess you can use nano, vi or vim as editor for editing the settings file.

You must configure a persistent storage volume to be mounted on /data otherwise you will indeed lose your flows every time you redeploy.
