Storage Secrets
If you want to connect your MetaCentrum home to any of the offered applications or you want to connect it to your own deployment, you have to generate a specific set of objects. To simplify the process we provide a website where you can generate either SSH secrets for accessing storage servers or directly usable PVC to access common storage brno-12 inside our Kubernetes cluster.
As of right now you can create 2 types of objects:
- SSH key for accessing SSHFS or to connect via SSH to one of our servers which is saved as Kubernetes Secret
- PVC representing your
brno-12home can be directly connected
To create the objects, visit https://storagesecrets.cloud.e-infra.cz/
Reuqirements before use
To use this service you must be a part of the META kerberos realm, simply put: you must have MetaCentrum account.
❗️In addition to being in the correct realm you also need to have your kerberos name associated with your Rancher account. This association should happen automatically upon login to Rancher, but is a recent addition, so you may have to log out and back into Rancher at https://rancher.cloud.e-infra.cz. It may take up to 5 minutes for your kerberos name to be associated with your Rancher account, so please wait a bit before trying to access the site again.
Using the site
The site provides you with a form where you can select what type of object you want to create and which server you want to access with it.
At the bottom of the site is a namespace selector, here you should select a namespace into which the generated objects will be saved. If you don’t know what a namespace is or need a quick refresher, you can find more information here.
Once you press the “Submit” button your secrets are generated and saved in your desired namespace. You can use Rancher UI to access your secrets and view their contents.
What to use the secrets for
You can use the Samba secret for example when launching a Matlab application to use your home directory on storage-brno12-cerit.metacentrum.cz as persistent storage.
