We don't support using the impersonate headers through the impersonation
proxy yet, so this integration test is a negative test which asserts
that we get an error.
- The CA cert will end up in the end user's kubeconfig on their client
machine, so if it changes they would need to fetch the new one and
update their kubeconfig. Therefore, we should avoid changing it as
much as possible.
- Now the controller writes the CA to a different Secret. It writes both
the cert and the key so it can reuse them to create more TLS
certificates in the future.
- For now, it only needs to make more TLS certificates if the old
TLS cert Secret gets deleted or updated to be invalid. This allows
for manual rotation of the TLS certs by simply deleting the Secret.
In the future, we may want to implement some kind of auto rotation.
- For now, rotation of both the CA and TLS certs will also happen if
you manually delete the CA Secret. However, this would cause the end
users to immediately need to get the new CA into their kubeconfig,
so this is not as elegant as a normal rotation flow where you would
have a window of time where you have more than one CA.
Should work on cluster which have:
- load balancers not supported, has squid proxy (e.g. kind)
- load balancers supported, has squid proxy (e.g. EKS)
- load balancers supported, no squid proxy (e.g. GKE)
When testing with a load balancer, call the impersonation proxy through
the load balancer.
Also, added a new library.RequireNeverWithoutError() helper.

There is a new feature in 1.20 that creates a ConfigMap by default in each namespace: https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.20.md#introducing-rootcaconfigmap
This broke this test because it assumed that all the ConfigMaps in the ephemeral test namespace were those created by the test code. The fix is to add a test label and rewrite our assertions to filter with it.

Also:
- Shut down the informer correctly in

- Changed base64 encoding of impersonator bearer tokens to use

by the impersonator more carefully in the unit tests

This is a partial revert of 288d9c999e. For some reason it didn't occur to me
that we could do it this way earlier. Whoops.
This also contains a middleware update: mutation funcs can return an error now
and short-circuit the rest of the request/response flow. The idea here is that
if someone is configuring their kubeclient to use middleware, they are agreeing
to a narrow-er client contract by doing so (e.g., their TokenCredentialRequest's
must have an Spec.Authenticator.APIGroup set).
I also updated some internal/groupsuffix tests to be more realistic.
Signed-off-by: Andrew Keesler <akeesler@vmware.com>
I think the reason we were seeing flakes here is because the kube cert agent
pods had not reached a steady state even though our test assertions passed, so
the test would proceed immediately and run more assertions on top of a weird
state of the kube cert agent pods.

This allows us to keep all of our resources in the pinniped category
while not having kubectl return errors for calls such as:
kubectl get pinniped -A
Signed-off-by: Monis Khan <mok@vmware.com>
When the Pinniped server has been installed with the `api_group_suffix`
option, for example using `mysuffix.com`, then clients who would like to
submit a `TokenCredentialRequest` to the server should set the
`Spec.Authenticator.APIGroup` field as `authentication.concierge.mysuffix.com`.
This makes more sense from the client's point of view than using the
default `authentication.concierge.pinniped.dev` because
`authentication.concierge.mysuffix.com` is the name of the API group
that they can observe their cluster and `authentication.concierge.pinniped.dev`
does not exist as an API group on their cluster.
This commit includes both the client and server-side changes to make
this work, as well as integration test updates.

Because it is a test of the conciergeclient package, and the naming
convention for integration test files is supervisor_*_test.go,
concierge_*_test.go, or cli_*_test.go to identify which component
the test is primarily covering.

Yes, this is a huge commit.
The middleware allows you to customize the API groups of all of the
*.pinniped.dev API groups.
Some notes about other small things in this commit:
- We removed the internal/client package in favor of pkg/conciergeclient. The
two packages do basically the same thing. I don't think we use the former
anymore.
- We re-enabled cluster-scoped owner assertions in the integration tests.
This code was added in internal/ownerref. See a0546942 for when this
assertion was removed.
- Note: the middlware code is in charge of restoring the GV of a request object,
so we should never need to write mutations that do that.
- We updated the supervisor secret generation to no longer manually set an owner
reference to the deployment since the middleware code now does this. I think we
still need some way to make an initial event for the secret generator
controller, which involves knowing the namespace and the name of the generated
secret, so I still wired the deployment through. We could use a namespace/name
tuple here, but I was lazy.

The group claims read from the session cache file are loaded as `[]interface{}` (slice of empty interfaces) so when we previously did a `groups, _ := idTokenClaims[oidc.DownstreamGroupsClaim].([]string)`, then `groups` would always end up nil.
The solution I tried here was to convert the expected value to also be `[]interface{}` so that `require.Equal(t, ...)` does the right thing.
This bug only showed up in our acceptance environnment against Okta, since we don't have any other integration test coverage with IDPs that pass a groups claim.

We were seeing a race in this test code since the require.NoError() and
require.Eventually() would write to the same testing.T state on separate
goroutines. Hopefully this helper function should cover the cases when we want
to require.NoError() inside a require.Eventually() without causing a race.

See comment. This is at least a first step to make our GKE acceptance
environment greener. Previously, this test assumed that the Pinniped-under-test
had been deployed in (roughly) the last 10 minutes, which is not an assumption
that we make anywhere else in the integration test suite.

- Only sync on add/update of secrets in the same namespace which
have the "storage.pinniped.dev/garbage-collect-after" annotation, and
also during a full resync of the informer whenever secrets in the
same namespace with that annotation exist.
- Ignore deleted secrets to avoid having this controller trigger itself
unnecessarily when it deletes a secret. This controller is never
interested in deleted secrets, since its only job is to delete
existing secrets.
- No change to the self-imposed rate limit logic. That still applies
because secrets with this annotation will be created and updated
regularly while the system is running (not just during rare system
configuration steps).
This is a bit more clear. We're changing this now because it is a non-backwards-compatible change that we can make now since none of this RFC8693 token exchange stuff has been released yet.
There is also a small typo fix in some flag usages (s/RF8693/RFC8693/)
