If for whatever reasons a repo already had a `release-tools` directory before doing a clean import of it with `git subtree`, the check used to fail because it found those old commits. This can be fixed by telling `git log` to stop when the directory disappears from the repo. There has to be a commit with removes the old content, because otherwise `git subtree add` doesn't work. Fixes: kubernetes-csi/external-resizer#21
verify-subtree.sh: relax check and ignore old content
In repos that have a test/e2e, that test suite should be run separately because it depends on a running cluster.
This is an unmodified copy of kubernetes/hack/verify-shellcheck.sh revision d5a3db003916b1d33b503ccd2e4897e094d8af77.
This runs "dep check" to verify that the vendor directory is up-to-date and meets expectations (= done with dep >= 0.5.0).

build.make: avoid unit-testing E2E test suite
These are the modifications that were necessary to call this outside of Kubernetes. The support for excluding files from checking gets removed to simplify the script. It shouldn't be needed, because linting can be enabled after fixing whatever scripts might fail the check.
By default this only tests the scripts inside the "release-tools" directory, which is useful when making experimental changes to them in a component that uses csi-release-tools. But a component can also enable checking for other directories.
This enables testing of other repos and of this repo itself inside
Prow. Currently supported is unit testing ("make test") and E2E
testing (either via a local test suite or the Kubernetes E2E test
suite applied to the hostpath driver example deployment).
The script passes shellcheck and uses Prow to verify that for future
PRs.
verify shellcheck
The travis.yml is now the only place where the Go version for the component itself needs to be configured.
Using the same (recent) Go version for all Kubernetes versions can break for older versions when there are incompatible changes in Go. To avoid that, we use exactly the minimum version of Go required for each Kubernetes version. This is based on the assumption that this combination was tested successfully. When building the E2E suite from Kubernetes (the default) we do the same, but still allow building it from elsewhere. We allow the Go version to be empty when it doesn't matter.
While switching back and forth between release-1.13 and release-1.14 locally, there was the problem that the local kind image kept using the wrong kubelet binary despite rebuilding from source. The problem went away after cleaning the Bazel cache. Exact root cause unknown, but perhaps using unique tags and properly cleaning the repo helps. If not, then the unique tags at least will show what the problem is.
Instead of always using the latest E2E tests for all Kubernetes versions, the plan now is to use the tests that match the Kubernetes version. However, for 1.13 we have to make an exception because the suite for that version did not support the necessary --storage.testdriver parameter.
The temporary fork was merged, we can use the upstream repo again.
Prow testing
This ensures that also new, currently unknown alpha gates are enabled when testing against a future Kubernetes versions. For all currently known Kubernetes versions we just use the minimal set of alpha gates, which ensures that we don't miss any of them in our documentation.
"grep -w" treated "serial-alpha" as two words and therefore CSI_PROW_TESTS sometimes ran too many tests.
The previous logic failed for canary jobs, those also deploy a recent driver. Instead of guessing what driver gets installed based on job parameters, check what really runs in the cluster and base the decision on that. We only need to maintain this blacklist for 1.0.x until we replace it with 1.1.0, then this entire hostpath_supports_block can be removed.
When running only some tests, sometimes extra, unnecessarily work was done, like bringing up the cluster without alpha gates.
Not all environments have Docker. The simplifying assumption here is that if the Docker command is available, it's also usable.
When KinD fails in a Prow job, we need additional information to understand why it failed.
It turned out to not work. Instead of reverting the commit which introduced this, let's better document this explicitly.
prow enhancements
This was already meant to be done earlier in cda2fc5. While at it, extend the permanent TODO with guidance on future feature gates.

We can keep the current k8s version for now to minimize changes, and update it later. Unless it's causing vendor issues. |
