Nuvolos supports setting custom environment variables for your applications at the account level. You can configure variables in the Settings -> Environment tab.
Nuvolos supports setting custom secrets for your applications at the account, space and organization level. The different secrets are treated similarly within the applications, the only difference is the permissions to read, create, update and delete them.
All Nuvolos users can set secrets for their account. You can configure variables and secrets in the Settings -> Secrets tab.
A good use case for account secrets is personal access tokens for third party vendors, like Hugging Face, OpenAI, etc. Any token you set at account level will be automatically available to all your apps, but only for you, and not other users in the same org/space.
Nuvolos supports setting custom secrets for spaces, that are available for all members in the space who are viewers in at least one instance of the particular space.
You can see (and configure) space secrets in the Manage Space -> Course/Project Configuration -> Secrets tab.
Only users with Space Administrator Role have the permission to create, update and delete space secrets.
A good example for space level secrets is connection credentials for a shared third party resource like a database server, where distinct Nuvolos users can use the same credentials. However, we generally recommend to create separate users with separate secrets on third party resource as well for better security and auditing purposes. Even in this case, many settings can be set at the space level (e.g. database hostname, port, certificate, etc.)
Nuvolos also supports setting custom secrets for a whole organization, that are available for all members in the particular orginization.
As an Organization Manager, you can configure organization secrets in the Organization settings -> Secrets tab from the dropdown settings menu on the dashboard.
Only users with Organization Manager Role have the permission to access the Secrets tab, where they can create, update and delete organization secrets.
In order to decide which secrets are available in a running application, an override policy is implemented as follows:
Hierarchy level: Organization secret < Space secret < Account secret, where personal secrets are the highest in hierarchy.
In case there are secrets defined with the same name on different hierarchy levels, the above defined order takes place to determine the effective secrets for a given application.
For example, the Organization Manager has set an Organization secret called ACCESS_KEY with an arbitrary value, but you have an Account secret with the same name. When you launch an application in the organization with the mentioned secret set, you will notice that upon reading the environment variables, you get the value for the ACCESS_KEY secret that you set for your account. The similar logic applies for all other pairs of secrets in the hieararchy level.
Both variables and secrets are made available in running applications. There are slight differences in how secrets and environmental variables are treated:
Environmental variables:
Become environmental variables in running applications.
Values can be viewed from the Web UI.
Subprocesses may or may not inherit them when spawned.
Secrets:
Become environmental variables in running applications.
Also become files that are located under the /secrets folder, where the filename is the secret name and the content of the file is the secret value.
Values cannot be viewed from the Web UI.
Since stored in a fix location, any spawned subprocesses are able to access them in a straightforward manner from the /secretsfolder.
As a member of an organization, you can access organization secrets on the Secrets tab in the Space configuration menu as shown . Note, that on this screen all space secrets appear alongside the organization secrets that are not by space secrets.
If you would like to avoid overriding Organization and Space secrets, always make sure to check their names before creating Account secrets!
