I have a problem using the exec node.
Maybe I miss something fundamental. Any Information might help.
The goal was to use a command like this:
_fswebcam --rotate 270 /home/pi/nodehttpd/image.jpg_
Node Red is started in a Docker container via Docker-Compose.
```auto
nodered:
container_name: nodered
build: ./services/nodered/.
privileged: true
restart: unless-stopped
user: "1000"
ports:
- 1880:1880
volumes:
- ./volumes/nodered/data:/data
```
"fswebcam" is installed on the host.
I cannot executed it, even with a shell script in the shares /data folder. direct paths etc tested.
Debug : "command not found"
Any suggestions?

Did you try giving the full path to the command ?

Yes,
in the exec node I also tried:
_/usr/bin/fswebcam --rotate 270 /home/pi/nodehttpd/image.jpg_
I also tried it with a simple bash script in the data folder (getpic.sh), containing the commands above
exec command then was:
_bash /data/getpc.sh_

the container has it's own isolated file system (that is kind of the point :-). so you would need to either ssh back out of the container to the host - or mount (or maybe alias) the command into the mounted volume (but then it may not have access to all the required libraries (if any are needed))

Thank you for help, dceejay.
As workaround I use a **node.js** script as webserver now.
calling it by [http://IPADDRESS:8888/](http://IPADDRESS:8888/)
```auto
var http = require("http");
const exec = require("child_process").exec;
function onRequest(request, res) {
console.log("Request received.");
var child = exec('bash /home/pi/campic.sh', function(err, stdout, stderr) {
console.log(stdout);
console.log(stderr);
if (err !== null) {
console.log(`exec error: ${err}`);
}
});
}
http.createServer(onRequest).listen(8888, function () {
console.log("Server has started.");
});
```
If someone has a better idea, please let me know.
