You can use an older version of K8s on your development workstation
by temporarily editing kind-up.sh to add the `--image` flag. By defining
both v1beta2 and v1beta3 you should continue to be able to use old
versions of K8s in this way with Kind v0.12.0.
It appears that kind completely ignores kubeadm.k8s.io/v1beta2 config
starting in Kind v0.12.0.
You can observe the config being ignored or used by adding `-v 10` to
the command-line arguments of `kind create cluster` in kind-up.sh.
- Two of the linters changed their names
- Updated code and nolint comments to make all linters pass with 1.44.2
- Added a new hack/install-linter.sh script to help developers install
the expected version of the linter for local development
- Note that v0.8.0 no longer supports the "trivialVersions=true"
command-line option, so remove that from update-codegen.sh.
It doesn't seem to impact the output (our generated CRD yaml files).
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
The purpose of this change is to allow Helm to be used to deploy Pinniped
into the local KinD cluster for the local integration tests. That said,
the change allows any alternate deployment mechanism, I just happen
to be using it with Helm.
All default behavior is preserved. This won't change how anyone uses the
script today, it just allows me not to copy/paste the whole setup for the
integration tests.
Changes:
1) An option called `--alternate-deploy <path-to-deploy-script>` has been
added, that when enabled calls the specified script instead of using ytt
and kapp. The alternate deploy script is called with the app to deploy
and the tag of the docker image to use. We set the default value of
the alternate_deploy variable to undefined, and there is a check that
tests if the alternate deploy is defined. For the superivsor it looks
like this:
```
if [ "$alternate_deploy" != "undefined" ]; then
log_note "The Pinniped Supervisor will be deployed with $alternate_deploy pinniped-supervisor $tag..."
$alternate_deploy pinniped-supervisor $tag
else
normal ytt/kapp deploy
fi
```
2) Additional log_note entries have been added to enumerate all values passed
into the ytt/kapp deploy. Used while I was trying to reach parity in the integration
tests, but I think they are useful for debugging.
3) The manifests produced by ytt and written to /tmp are now named individually.
This is so an easy comparison can be made between manifests produced by a ytt/kapp
run of integration tests and manifests produced by helm run of the integration tests.
If something is not working I have been comparing the manifests after these runs to
find differences.
This change allows configuration of the http and https listeners
used by the supervisor.
TCP (IPv4 and IPv6 with any interface and port) and Unix domain
socket based listeners are supported. Listeners may also be
disabled.
Binding the http listener to TCP addresses other than 127.0.0.1 or
::1 is deprecated.
The deployment now uses https health checks. The supervisor is
always able to complete a TLS connection with the use of a bootstrap
certificate that is signed by an in-memory certificate authority.
To support sidecar containers used by service meshes, Unix domain
socket based listeners include ACLs that allow writes to the socket
file from any runAsUser specified in the pod's containers.

This change updates the TLS config used by all pinniped components.
There are no configuration knobs associated with this change. Thus
this change tightens our static defaults.
There are four TLS config levels:
1. Secure (TLS 1.3 only)
2. Default (TLS 1.2+ best ciphers that are well supported)
3. Default LDAP (TLS 1.2+ with less good ciphers)
4. Legacy (currently unused, TLS 1.2+ with all non-broken ciphers)
Highlights per component:
1. pinniped CLI
- uses "secure" config against KAS
- uses "default" for all other connections
2. concierge
- uses "secure" config as an aggregated API server
- uses "default" config as a impersonation proxy API server
- uses "secure" config against KAS
- uses "default" config for JWT authenticater (mostly, see code)
- no changes to webhook authenticater (see code)
3. supervisor
- uses "default" config as a server
- uses "secure" config against KAS
- uses "default" config against OIDC IDPs
- uses "default LDAP" config against LDAP IDPs

This should make it easier for us to to notice if something is wrong
with our service (especially in any future kubectl tests we add).

Those images that are pulled from Dockerhub will cause pull failures
on some test clusters due to Dockerhub rate limiting.
Because we already have some images that we use for testing, and
because those images are already pre-loaded onto our CI clusters
to make the tests faster, use one of those images and always specify
PullIfNotPresent to avoid pulling the image again during the integration
test.
This required a weird hack because some of the Fosite tests (or a transitive dependency of them) depends on a newer version of gRPC that's incompatible with the Kubernetes runtime version we use. It wasn't as simple as just replacing the gRPC module with an older version, because in the latest versions of gRPC, they split out the "examples" packages into their own module. This new module name doesn't exist at the old version.
Ultimately, the workaround was to make a fake "examples" module locally. This module can be empty because we never actually depend on that code (it's only used in transitive dependency tests).

- The linux base64 command is different, so avoid using it at all.
On linux the default is to split the output into multiple lines,
which messes up the integration-test-env file. The flag used to
disable this behavior on linux ("-w0") does not exist on MacOS's
base64.
- On debian linux, the latest version of Docker from apt-get still
requires DOCKER_BUILDKIT=1 or else it barfs.
