Proof-of-concept implementation of a potential new Supervisor feature
which allows arbitrary upstream ID token claims to be mapped into a
new top-level claim in the ID tokens issued by the Supervisor.
- Change update-codegen.sh script to also generated openapi code for the
aggregated API types
- Update both aggregated API servers' configuration to make them serve
the openapi docs for the aggregated APIs
- Add new integration test which runs `kubectl explain` for all Pinniped
API resources, and all fields and subfields of those resources
- Update some the comments on the API structs
- Change some names of the tmpl files to make the filename better match
the struct names
- For backwards compatibility with older Pinniped CLIs, the pinniped-cli
client does not need to request the username or groups scopes for them
to be granted. For dynamic clients, the usual OAuth2 rules apply:
the client must be allowed to request the scopes according to its
configuration, and the client must actually request the scopes in the
authorization request.
- If the username scope was not granted, then there will be no username
in the ID token, and the cluster-scoped token exchange will fail since
there would be no username in the resulting cluster-scoped ID token.
- The OIDC well-known discovery endpoint lists the username and groups
scopes in the scopes_supported list, and lists the username and groups
claims in the claims_supported list.
- Add username and groups scopes to the default list of scopes
put into kubeconfig files by "pinniped get kubeconfig" CLI command,
and the default list of scopes used by "pinniped login oidc" when
no list of scopes is specified in the kubeconfig file
- The warning header about group memberships changing during upstream
refresh will only be sent to the pinniped-cli client, since it is
only intended for kubectl and it could leak the username to the
client (which may not have the username scope granted) through the
warning message text.
- Add the user's username to the session storage as a new field, so that
during upstream refresh we can compare the original username from the
initial authorization to the refreshed username, even in the case when
the username scope was not granted (and therefore the username is not
stored in the ID token claims of the session storage)
- Bump the Supervisor session storage format version from 2 to 3
due to the username field being added to the session struct
- Extract commonly used string constants related to OIDC flows to api
package.
- Change some import names to make them consistent:
- Always import github.com/coreos/go-oidc/v3/oidc as "coreosoidc"
- Always import go.pinniped.dev/generated/latest/apis/supervisor/oidc
as "oidcapi"
- Always import go.pinniped.dev/internal/oidc as "oidc"
The following validation is enforced:
1. Names must start with client.oauth.pinniped.dev-
2. Redirect URIs must start with https://
or http://127.0.0.1
or http://::1
3. All spec lists must not have duplicates
Added an integration test to assert all static validations.

Note that attempting to update 1.18.18 to 1.18.20 didn't work for some
reason, so I skipped that one. The code generator didn't like 1.18.20
and it deleted all the generated code. Avoiding 1.18.19 because it is
listed as having a regression at
https://kubernetes.io/releases/patch-releases/#non-active-branch-history
Also:
- Make our code generator script work with Go 1.17
- Make our update.sh script work on linux
- Update the patch versions of the old Kube versions that we were using
to generate code (see kube-versions.txt)
- Use our container images from ghcr instead of
projects.registry.vmware.com for codegen purposes
- Make it easier to debug in the future by passing "-v" to the Kube
codegen scripts
- Updated copyright years to make commit checks pass
