Add make target for generating TLS certs for etcd resource. #1269
Description
How to categorize this issue?
/area dev-productivity
/kind enhancement
What would you like to be added:
Add a make target that uses the publicly available PKI generation functions to generate TLS certs for a given namespace and etcd name and applies the secrets that reference these generated certs and keys.
These can be generated in a tools directory which can be added under .gitignore.
Why is this needed:
The new e2e tests as raised in #1060 removed the existing directory where TLS certs and artefacts were maintained in order to programmatically generate them as and when needed. The functions written to do so can be leveraged to a make target to generate said certs for local development and testing for TLS based setups.
This can then be added in the guide as mentioned in #1258
