The gzip plugin is deprecated in nbdkit ≥ 1.22.17 and will beremoved in nbdkit 1.26. It has been replaced with a filter with the same functionality, see nbdkit-gzip-filter(1). You can use the filter like this:
nbdkit file --filter=gzip FILENAME.gz
Overview
"nbdkit-gzip-plugin" is a file serving plugin for nbdkit(1).
It serves the named "FILENAME.gz" over NBD, uncompressing it on the fly. The plugin only supports read-only connections.
Note that gzip files are not very good for random access in large files because seeking to a position in the gzip file involves uncompressing lots of data. A more practical method to compress large disk images is to use the xz(1) format and nbdkit-xz-filter(1).
Parameters
[file=]FILENAME.gz
Serve the compressed file named "FILENAME.gz".
This parameter is required.
"file=" is a magic config key and may be omitted in most cases. See "Magic parameters" in nbdkit(1).
Files
$plugindir/nbdkit-gzip-plugin.so
The plugin.
Use "nbdkit --dump-config" to find the location of $plugindir.
Version
