The Logstash plugin manager provides support for preparing offline plugin packs that you can use to install Logstash plugins on systems that don’t have Internet access.
This procedure requires a staging machine running Logstash that has access to a public or private Rubygems server. The staging machine downloads and packages all the files and dependencies required for offline installation.
Building Offline Plugin Packsedit
An offline plugin pack is a compressed file that contains all the plugins your offline Logstash installation requires, along with the dependencies for those plugins.
To build an offline plugin pack:
- Make sure all the plugins that you want to package are installed on the staging server and that the staging server can access the Internet.
bin/logstash-plugin prepare-offline-packsubcommand to package the plugins and dependencies:
bin/logstash-plugin prepare-offline-pack --output OUTPUT --overwrite [PLUGINS]
OUTPUTspecifies the zip file where the compressed plugin pack will be written. The default file is
/LOGSTASH_HOME/logstash-offline-plugins-7.8.1.zip. If you are using 5.2.x and 5.3.0, this location should be a zip file whose contents will be overwritten.
[PLUGINS]specifies one or more plugins that you want to include in the pack.
--overwritespecifies if you want to override an existing file at the location
Packages the Beats input plugin and any dependencies.
Uses a wildcard to package all filter plugins and any dependencies.
Packages all filter plugins, the Beats input plugin, and any dependencies.
Downloading all dependencies for the specified plugins may take some time, depending on the plugins listed.
Installing Offline Plugin Packsedit
To install an offline plugin pack:
- Move the compressed bundle to the machine where you want to install the plugins.
bin/logstash-plugin installsubcommand and pass in the file URI of the offline plugin pack.
bin/logstash-plugin install file:///c:/path/to/logstash-offline-plugins-7.8.1.zip
bin/logstash-plugin install file:///path/to/logstash-offline-plugins-7.8.1.zip
This command expects a file URI, so make sure you use forward slashes and specify the full path to the pack.
Updating Offline Pluginsedit
To update offline plugins, you update the plugins on the staging server and then use the same process that you followed to build and install the plugin pack:
