# Nexus
|
||||
|
||||
[Nexus](https://www.sonatype.com/nexus-repository-oss) is the world's only repository manager with FREE support for popular formats
|
||||
|
||||
## Introduction
|
||||
|
||||
This chart bootstraps a sonatype nexus instance
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Kubernetes 1.6+
|
||||
|
||||
## Installing the Chart
|
||||
|
||||
To install the chart:
|
||||
|
||||
```bash
|
||||
$ helm install stable/sonatype-nexus
|
||||
```
|
||||
|
||||
The above command deploys Nexus on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
|
||||
|
||||
The default login is admin/admin123
|
||||
|
||||
## Uninstalling the Chart
|
||||
|
||||
to uninstall/delete the deployment:
|
||||
|
||||
```bash
|
||||
$ helm list
|
||||
NAME REVISION UPDATED STATUS CHART NAMESPACE
|
||||
plinking-gopher 1 Fri Sep 1 13:19:50 2017 DEPLOYED nexus-0.1.0 default
|
||||
$ helm delete plinking-gopher
|
||||
```
|
||||
|
||||
The command removes all the Kubernetes components associated with the chart and deletes the release.
|
||||
|
||||
## Configuration
|
||||
|
||||
The following tables lists the configurable parameters of the Nexus chart and their default values.
|
||||
|
||||
| Parameter | Description | Default |
|
||||
| ------------------------------------------ | ---------------------------------- | -------------------------------------------|
|
||||
| `imageTag` | `nexus` image tag. | 3.5.1-02 |
|
||||
| `imagePullPolicy` | Image pull policy | `IfNotPresent` |
|
||||
| `ingress.enabled` | Flag for enabling ingress | false |
|
||||
| `persistence.enabled` | Create a volume to store data | true |
|
||||
| `persistence.size` | Size of persistent volume to claim | 8Gi RW |
|
||||
| `persistence.storageClass` | Type of persistent volume claim | nil (uses alpha storage class annotation) |
|
||||
| `persistence.accessMode` | ReadWriteOnce or ReadOnly | ReadWriteOnce |
|
||||
| `service.type` | Kubernetes Service type | `ClusterIP` |
|
||||
| `service.readinessProbe.initialDelaySeconds`| ReadinessProbe initial delay | 30 |
|
||||
| `service.readinessProbe.periodSeconds` | Seconds between polls | 30 |
|
||||
| `service.readinessProbe.failureThreshold` | Number of attempts before failure | 6 |
|
||||
| `service.livenessProbe.initialDelaySeconds` | livenessProbe initial delay | 30 |
|
||||
| `service.livenessProbe.periodSeconds` | Seconds between polls | 30 |
|
||||
|
||||
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
|
||||
|
||||
```bash
|
||||
$ helm install --name my-release \
|
||||
--set persistence.enabled=false \
|
||||
stable/sonatype-nexus
|
||||
```
|
||||
The above example turns off the persistence. Data will not be kept between restarts or deployments
|
||||
|
||||
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
|
||||
|
||||
```bash
|
||||
$ helm install --name my-release -f values.yaml stable/sonatype-nexus
|
||||
```
|
||||
|
||||
> **Tip**: You can use the default [values.yaml](values.yaml)
|
||||
|
||||
## Persistence
|
||||
|
||||
The [Nexus](https://github.com/clearent/nexus) image stores its data and configurations at the `/nexus-data` path of the container.
|
||||
|
||||
By default a PersistentVolumeClaim is created and mounted into that directory. In order to disable this functionality
|
||||
you can change the values.yaml to disable persistence and use an emptyDir instead.
|
||||
|
||||
> *"An emptyDir volume is first created when a Pod is assigned to a Node, and exists as long as that Pod is running on that node. When a Pod is removed from a node for any reason, the data in the emptyDir is deleted forever."*
