I have an IoT 2050 using the Example Image V01.03.01

I need to send some data using node-red to the mindsphere using the mindConnect node through a proxy.

I cannot try the solution by tautom in this post because in Image V01.03.01 the file /usr/lib/systemd/system/node-red.service cannot be edited, it is a readonly file (filesystem of type squashfs)

------------------------------------------------------------------------------------------
Split from node-red behind proxy.

Instead of modifying the readonly .service file /usr/lib/systemd/system/node-red.service

I copied it to /etc/systemd/system/node-red-proxied.service and added the environment lines

Environment="HTTP_PROXY=my-proxy-server-address"
Environment="HTTPS_PROXY=my-proxy-server-address"
Environment="FTP_PROXY=my-proxy-server-address"
Environment="NO_PROXY=127.0.0.1,localhost"

then I disabled node-red.service and enabled node-red-proxied.service

root@iot2050-debian:/#systemctl stop node-red
root@iot2050-debian:/#systemctl disable node-red
root@iot2050-debian:/#systemctl enable node-red-proxied
root@iot2050-debian:/#systemctl start node-red-proxied

After this node-red is connecting online behind the proxy. 🦾

I am now experiencing another issue, this time with the MindConnect Node-RED Agent v3.12.1 node, I cannot configure the node because it is trying to write to the same read-only filesystem, the error now is

"Error: EROFS: read-only file system, mkdir '//.mc/'"

From this Github post, I was able to locate the file were the storage path for Mindconnect node is defined, I just changed the path to a writable folder

modified line 540 in file mindconnect-nodejs/src/api/agent-auth.ts 

from

basePath:string|IConfigurationStorage=process.cwd()+"/.mc/"

 to

basePath:string|IConfigurationStorage="/home/root/.mc/"

bergmanu, thank you for your interest in this issue, I cloned the project from

https://github.com/siemens/meta-iot2050

and build it with the command

 ./kas-container menu

 This is the output of /etc/*-release from the built image
