nexus-oss-npm-proxy

Nexus Registry can be used to setup as proxy to the npm/maven registry and reduce more downloads from public internet

Start Server

Using Openshift

oc new-app sonatype/nexus:oss

Using single Docker container

docker run -d -p 8081:8081 --name nexus sonatype/nexus:oss
(or)
docker run -d -p 8081:8081 --name nexus -v /some/dir/nexus-data:/sonatype-work sonatype/nexus

Using Two Docker containers for persistent storage

docker run -d --name nexus-data sonatype/nexus:oss echo "data-only container for Nexus"
docker run -d -p 8081:8081 --name nexus --volumes-from nexus-data sonatype/nexus:oss

wait for atleast 10mins for the registry to initialize and hit this endpoint

curl http://localhost:8081/nexus/service/local/status

Server Setup

After the health endpoint is active, try accessing the UI http://localhost:8081/nexus

Login using the default credentials admin/admin123

NPM Server Setup

Create a new Repository -> Proxy Repository -> npm -> Fill the form input registry for npm https://registry.npmjs.org

Get the Repository path from UI (similar to http://localhost:8081/nexus/content/repositories/npm-all)

Validate

Goto any node project directory

create .npmrc file with following contents

registry = http://localhost:8081/nexus/content/repositories/badam/

Run a sample npm install command

npm install grunt

Check the time of duration

time npm install grunt

Check if the local npm registry is hitting our proxy server

npm --loglevel info install grunt

check this curl http://localhost:8081/nexus/content/repositories/badam/ to find out cached repositories

Maven Server Setup

Create a new Repository -> Proxy Repository -> maven -> Fill the form input registry for maven http://repo.maven.apache.org/maven2/

Get the Repository path from UI (similar to http://localhost:8081/nexus/content/repositories/mvn-all/)

Validate

update mvn settings.xml (~/.m2/settings.xml)
