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

• 1 NEXUS container

• 1 MOLGENIS-httpd container (to proxy the registry and docker to one domain)

Backup restore

There are two steps in restoring the NEXUS.

• Database
• Blobstore

Restore the database

Go to the commandline:

kubectl get pv

| 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:

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.
