Adding unit test verify that deleteValidation is retried.
adding e2e test verifying the webhook can intercept configmap and custom
resource deletion, and the existing object is sent via the
admissionreview.OldObject.
update the admission integration test to verify that the existing object
is passed to the deletion admission webhook as oldObject, in case of an
immediate deletion and in case of an update-on-delete.
The dnsutils and jessie-dnsutils images are installing dnsmasq,
which is required for a few tests checking custom DNS servers and
configurations.
dnsmasq is a Linux specific binary. In order for the tests to also
pass on Windows, this commit adds CoreDNS to the images, so a later
commit will update the tests to use CoreDNS instead of dnsmasq.
The container might start before all the networking plumbing has
been sucessfully completed, causing the Kubernetes reachability
check to fail.
This commit adds a few retries to the connectivity check.
Dockerhub does not support slashes in the image names, so when the tests are
configured to use a dockerhub registry instead of the current
gcr.io/kubernetes-e2e-test-images registry, the tests using the mentioned image
will fail, as the image cannot exist and cannot be pulled.
Adds the following subcommands to the agnhost binary:
- dns-server-list: outputs the host's DNS server list with which it was
configured with. This can be found in /etc/resolv.conf on Linux and
through some powershell commands on Windows.
- etc-hosts: outputs the host's hosts file. This can be found in /etc/hosts
for Linux, and C:/Windows/System32/drivers/etc/hosts for Windows.
- pause: pauses the binary's execution. This can be used to keep the Pod in
a Running state for various reasons, including executing additional agnhost
commands.
Refactors bits of the code to avoid duplication.
Adds a README for the agnhost image.
iSCSI target (=the server) is implemented in Linux kernel. The "iSCSI
server" pod is not a real server, it just configures the kernel on the
host. In order to run iSCSI tests in parallel, we need to be able to
run multiple such pods on a single node, serving different LUNs to
different tests.
The "server pod" must run with HostNetwork=true to achieve that.
Each pod then creates its own IQN with namespace name, so it can't
collide with other server pods running in another namespaces on the same
node.
The new image is meant to be used for testing purposes, whenever there
are significant differences between Linux and Windows in the way
something is obtained or tested. For example, the DNS suffix list can
be found in ``/etc/resolv.conf`` on Linux, but on Windows, such file
does not exist, and one way to obtain the mentioned list would be
through some powershell commands.
The image contains an extendable CLI as the entrypoint, the tests
only having to add the necessary arguments. For the previous example,
passing the ``dns-suffix`` argument will print out the comma separated
DNS suffix list, on both Linux and Windows.
The image name means that it should behave the same way on any host,
no matter the host OS.
