[Workload] Security test: Is the CNF installable to an RBAC-enabled cluster?

[taylor]

Acceptance Criteria

[Platform] Security test: add test cnf_installable_to_rbac-enabled_cluster

Short description of workload test:

• This test is in alignment with the Principle of Least Privilege and the best practice for "CNFs should utilize RBAC roles"

Dependency:

• Enabling RBAC on K8s cluster. This functionality will be added in the platform ticket https://github.com/cncf/cnf-testsuite/issues/946

DRAFT Acceptance Criteria for peer review

Documentation is updated:

• [ ] USAGE.md documentation updated
  • [ ] how to run
  • [ ] details on what the best practice is
  • [ ] why are we testing this
• [ ] CATEGORIES updated
• [ ] If needed, https://github.com/cncf/cnf-testsuite/blob/main/CNF_TESTSUITE_YML_USAGE.md

Common steps

• [ ] Find or create a K8s cluster to use
  • Talk with team for access to an existing cluster
  • Kind K8s clusters will work as well
• [ ] Set the KUBECONFIG environment variable for accessing the target K8s cluster
• [ ] As a developer, Pull down latest version of CNF conformance test code from {FEATURE} branch
  • [ ] Check that {FEATURE} Branch passes all A/C
  • [ ] Check that {FEATURE} Branch passes tests in GitHub Actions
• [ ] As a peer reviewer, check that PR passes in GitHub Actions
  • [ ] if yes, merge PR to master
  • [ ] if no, make a comment and request that developer make changes to pass tests
• x] As a peer reviewer, Pull down latest version of CNF conformance test code from main branch
• [ ] Run shards install

Update Prerequisite checker

• [ ] NA

Update yml validator, if needed

• [ ] update if needed

I would expect Falco to successfully install when the falco setup command runs:

• [ ] Falco is not installed on the K8s cluster or system
• [ ] I run the setup command to install falco. Ex. cnf-testsuite setup falco
• [ ] I should see a message saying Falco was successfully installed

I would expect to PASSED for non_root_user test when running against a CNF which does not run processes as root:

• [ ] Tell the test suite to use a CNF which does not run any processes as root. eg. ./cnf-testsuite cnf_setup cnf-path=sample-cnfs/sample_nonroot
• [ ] Run the non-root user test: ./cnf-testsuite non_root_user
• [ ] I see a PASSED message. Example: PASSED: Root user not found 🚫√

I would expect to see a FAILED result for the non_root_user test, when running against CNF which has processes running as the root :

• [ ] Tell the test suite to use a CNF runs processes as root. eg. ./cnf-testsuite cnf_setup cnf-path=sample-cnfs/sample_coredns
• [ ] Run the non-root user test: ./cnf-testsuite non_root_user
• [ ] I see a PASSED message. Example: ❌ FAILED: Root user found 🚫√

I would expect to see a SKIPPED message for the non_root_user test, if Falco is not installed/available:

• [ ] Ensure Falco is not installed or accessible to the test suite (eg. not in PATH)
• [ ] Tell the test suite which CNF to use eg. ./cnf-testsuite cnf_setup cnf-path=sample-cnfs/sample_nonroot
• [ ] Run the non-root user test: ./cnf-testsuite non_root_user
• [ ] I see a SKIPPED message. Example: >> SKIPPED: Falco not installed, skipped the non_root_user test.

Screenshots of publish tarball test:

• [ ] I can see a screenshots of SUCCESS, FAILED and SKIPPED tests.
