All Lambda environments get 500MB of disk space. This is accessible in the /tmp directory. You can't just write to anywhere on the disk.

So in your example you'll need to do:

GZIPOutputStream gzos = new GZIPOutputStream(new FileOutputStream("/tmp/example.gz"));

If you really need it in a folder under /tmp then you'll first need to create the directory you could use something like:

Path outputPath = Files.createDirectories(Paths.get("/tmp/myfolder"));

to create the subdirectory under /tmp .
