This project adds Google Cloud Object Storage backed blobstores to Sonatype Nexus Repository 3 and later. It allows Nexus Repository to store the components and assets in Google Cloud instead of a local filesystem.
For the best experience, you should upgrade your Nexus Repository Manager and Google Cloud Blobstore plugin to the latest versions.
|Nexus Repository Manager 3 Version||Google Cloud Storage Blobstore Version|
This plugin uses the following Google Cloud Platform services:
Firestore usage is exclusively in Datastore mode; you must configure the project for your Repository Manager deployment to use "Firestore in Datastore mode".
To use this plugin (or execute the integration tests), you will need a service account with the following scopes:
Optionally, add the following for Cloud Logging:
The blobstore will create the storage bucket with the 'Multi-Regional' storage class.
Per the Google Cloud documentation:
GOOGLE_APPLICATION_CREDENTIALSenvironment variable for the user running Nexus:
After downloading the kar from Maven Central (links above), copy the kar file to the
deploy directory in your Nexus
Repository Manager install:
cp nexus-blobstore-google-cloud-*-bundle.kar /path/to/your/nxrm3/install/deploy
A restart of Nexus Repository Manager is required to complete the installation process.
Log in as admin and create a new blobstore, selecting 'Google Cloud Storage' as the type.
If you did not set the environment variable in Step 3 above, specify the absolute path to the JSON Service Account key file.
In version 0.10.0 and later, the plugin is capable of uploading content to the Google Cloud Storage bucket using multiple concurrent threads. In 0.12.0, this feature is disabled by default; see the corresponding design document.

Also, there is a good amount of information available at Bundle Development Overview
To build the project and generate the bundle use Maven:
mvn clean package
Optional: review the additional documentation to configure and run integration tests.
A docker-compose file is provided to ease setting up a local NXRM instance to test.
docker swarm init
docker volume create nexus3-data
docker secret create google_application_credentials /path/to/your/google/iam/key.json
You can also use the docker-compose file with docker service, like so:
docker stack deploy -c docker-compose.yml sonatype
(Using docker stack assumes you've built the container with
docker build -t nexus3-google . or run
docker-compose up at least once).
Last manual option: you can install the local development build in any NXRM install with:
cp target/*-bundle.kar /path/to/your/nxrm3/install/deploy
It is worth noting that this is NOT SUPPORTED by Sonatype, and is a contribution of ours to the open source community (read: you!)
Phew, that was easier than I thought. Last but not least of all:
Have fun creating and using this plugin and the Nexus platform, we are glad to have you here!
