# MOLGENIS - NEXUS Helm Chart
NEXUS repository for kubernetes to deploy on a kubernetes cluster with NFS-share
## Chart Details
This chart will deploy:
- 1 NEXUS-nfs initialization container
We need this container to avoid permission issues on the NEXUS docker
2018-06-27 22:06:41 +02:00
- 1 NEXUS container
- 1 MOLGENIS-httpd container (to proxy the registry and docker to one domain)
## Backup restore
2018-09-27 16:19:58 +02:00
There are two steps in restoring the NEXUS.
2018-09-27 16:19:58 +02:00
- Database
- Blobstore
### Restore the database
Go to the commandline:
```bash
kubectl get pv
```
```bash
| NAME | CAPACITY | ACCESS | MODES | RECLAIM | POLICY | STATUS | CLAIM | STORAGECLASS | REASON | AGE |
| ---- | -------- | ------ | ----- | ------- | ------ | ------ | ----- | ------------ | ------ | --- |
| pvc-45988f55-900f-11e8-a0b4-005056a51744 | 30G | RWX | | Retain | Bound | molgenis-nexus/molgenis-nfs-claim | nfs-provisioner-retain | | | 33d |
| pvc-3984723d-220f-14e8-a98a-skjhf88823kk | 30G | RWO | | Delete | Bound | molgenis-test/molgenis-nfs-claim | nfs-provisioner | | | 33d |
```
The persistent volume is the one in the molgenis-nexus namespace.
Go to the NFS-provisioner to the path of the persistent volume:
```bash
ls -t --full-time | head -7 | xargs cp ../restore-from-backup/
```

### Restore the blobstore
You can copy the directory ```blobs``` to the target persistent volume ```/ blobs```.
You can now bring the NEXUS back up.
