nexus3-cli 4.1.8

A python-based CLI for Sonatype Nexus OSS 3

nexus3-cli

A python-based command-line interface and API client for Sonatype's Nexus OSS 3.

Features

1. Compatible with Nexus 3 OSS
   1. Nexus versions tested
2. Python API and command-line support.
3. Artefact management: list, delete, bulk upload and download.
4. Repository management:
   1. Create hosted and proxy.
   2. Create apt, bower, docker, maven, npm, nuget, pypi, raw, rubygems, yum.
   3. Content type validation, version and write policy.
   4. Delete.
5. Groovy script management: list, upload, delete, run.
6. Clean-up policy management: create, list.
7. Task management: list, run, show stop.
8. Security management: realms.
9. Blob store management: list, show, create, delete, update (API only).

The actions above are performed using the Nexus REST API if the endpoint is available, otherwise a groovy script is used.

Please note that some Nexus 3 features are not currently supported. Assistance implementing missing support is very welcome. Please have a look at the issues and contribution guidelines.

Installation

The nexus3-cli package is available on PyPi. You can install using pip/pip3:

pip install nexus3-cli

There's also a docker image with nexus3-cli pre-installed.

Enable Groovy scripts

Some of the functionality in this client was written before the Nexus REST API exposed the necessary endpoints. For this reason, you may need to enable Groovy script execution in your instance.

See the FAQ in this blog post and the example nexus.properties in this project.

If you decide to leave groovy scripts disabled in your Nexus 3 instance, you need to disable its use in this client. This can be done by editing the ~/.nexus-cli configuration and changing groovy_enabled to false. Alternatively, you can export the NEXUS3_GROOVY_ENABLED=false environment variable.

Usage

Command line

For a quick start, use the sonatype/nexus3 Docker image:

docker run -d --rm -p 127.0.0.1:8081:8081 --name nexus sonatype/nexus3

Nexus will take a little while to start-up the first time you run it. You can tell when it's available by looking at the Docker instance logs or browsing to http://localhost:8081.

On older versions of the nexus3 Docker image, the default admin password is admin123; on newer versions it's automatically generated and you can find it by running docker exec nexus cat /nexus-data/admin.password.

The login command will store the service URL and your credentials in ~/.nexus-cli (warning: restrictive file permissions are set but the contents are saved in plain-text).

Setup CLI credentials:

$ nexus3 login
Nexus OSS URL (http://localhost:8081):
Nexus admin username (admin):
Nexus admin password (admin123):
Verify server certificate (True):

Configuration saved to /Users/thiago/.nexus-cli

List repositories:

$ nexus3 repository list
Name              Format   Type     URL
maven-snapshots   maven2   hosted   http://localhost:8081/repository/maven-snapshots
maven-central     maven2   proxy    http://localhost:8081/repository/maven-central
nuget-group       nuget    group    http://localhost:8081/repository/nuget-group
nuget.org-proxy   nuget    proxy    http://localhost:8081/repository/nuget.org-proxy
maven-releases    maven2   hosted   http://localhost:8081/repository/maven-releases
nuget-hosted      nuget    hosted   http://localhost:8081/repository/nuget-hosted
maven-public      maven2   group    http://localhost:8081/repository/maven-public

Create a repository:

nexus3 repository create hosted raw reponame

Do a recursive directory upload:

$ mkdir -p /tmp/some/deep/test/path
$ touch /tmp/some/deep/test/file.txt /tmp/some/deep/test/path/other.txt
$ cd /tmp; nexus3 up some/ reponame/path/
Uploading some/ to reponame/path/
[################################] 2/2 - 00:00:00
Uploaded 2 files to reponame/path/

Nota Bene: nexus3-cli interprets a path ending in / as a directory.

List repository contents:

$ nexus3 ls reponame/path/
path/some/deep/test/path/other.txt
path/some/deep/test/file.txt

For all commands, subcommands and options, run nexus3 -h. CLI documentation

API

See API documentation.

Development

The automated tests are configured in .gitlab-ci.yml. To run tests locally, install the package with test dependencies and run pytest:

pip install [--user] -e .[test]
pip install [--user] pytest faker
pytest -m 'not integration'

Integration tests require a local Nexus instance listening on 8081 or as configured in ~/.nexus-cli. The configuration file can be created using nexus3 login.

docker run -d --rm -p 127.0.0.1:8081:8081 --name nexus sonatype/nexus3
./tests/wait-for-nexus.sh  # the Nexus instance takes a while to be ready
# use the random admin password generated by the Nexus container to login
./tests/nexus-login $(docker exec nexus cat /nexus-data/admin.password)
pytest -m integration
docker kill nexus

Nota Bene: if you re-run integration tests without re-creating or cleaning-up the dev Nexus instance, test will fail because some objects created during tests will already exist.
