Please do not remove curl, I have many automations using curl getting json date from websites and (more important for me) from internal components like my not well supported thermostat and more.

Why can't you use the http-request node instead of shelling out to curl?
WeterPeter commentedon Apr 19, 2024
How to use http-request node doing this? :
curl -f -k -H 'Accept: application/json' -H 'Authorization: Bearer [LONG TOKEN]' -X GET https://192.168.xx.xx/api/v1/production/inverters

You can set headers on in the config for the http-request node or pass them in as
msg.headerAnd you can set the http-request node to not validate the server cerificate
hardillb commentedon Apr 19, 2024
You may also need to tell the http-request not not to validate the the response headers if the device isn't following the spec, but that option has been included in the 3.1.x stream since it was a security update to NodeJS 18 iirc

You can create simple Dockerfile which will install curl to your image:

In my experience (with IOTstack on Raspberry Pis and Debian Proxmox guests - but YMMV), it needs at least:
Why? You need to be root to run
apk. The base image on DockerHub leaves the user set to "node-red" (Dockerfile line 85). You inherit that at the point of theFROMso you have to switch to root to runapkand then put it back again. Putting it back to "node-red" is particularly important if you also use the Dockerfile to install add-on nodes.The
--no-cacheflag implies anapk updateand a corresponding cleanup. It's designed to minimise clutter and keep containers small. That said, it doesn't actually make a huge difference to container size (~2MB) so the traditional "update + add" is just as good.2024-07-30 Node-RED - master branch - PR 1 of 2
