* Move front-proxy-client certs back to kube mount
We want the same CA for all k8s certs
* Refactor vault to use a third party module
The module adds idempotency and reduces some of the repetitive
logic in the vault role
Requires ansible-modules-hashivault on ansible node and hvac
on the vault hosts themselves
Add upgrade test scenario
Remove bootstrap-os tags from tasks
* fix upgrade issues
* improve unseal logic
* specify ca and fix etcd check
* Fix initialization check
bump machine size
* using separated vault roles for generate certs with different `O` (Organization) subject field;
* configure vault roles for issuing certificates with different `CN` (Common name) subject field;
* set `CN` and `O` to `kubernetes` and `etcd` certificates;
* vault/defaults vars definition was simplified;
* vault dirs variables defined in kubernetes-defaults foles for using
shared tasks in etcd and kubernetes/secrets roles;
* upgrade vault to 0.8.1;
* generate random vault user password for each role by default;
* fix `serial` file name for vault certs;
* move vault auth request to issue_cert tasks;
* enable `RBAC` in vault CI;
* Added update CA trust step for etcd and kube/secrets roles
* Added load_balancer_domain_name to certificate alt names if defined. Reset CA's in RedHat os.
* Rename kube-cluster-ca.crt to vault-ca.crt, we need separated CA`s for vault, etcd and kube.
* Vault role refactoring, remove optional cert vault auth because not not used and worked. Create separate CA`s fro vault and etcd.
* Fixed different certificates set for vault cert_managment
* Update doc/vault.md
* Fixed condition create vault CA, wrong group
* Fixed missing etcd_cert_path mount for rkt deployment type. Distribute vault roles for all vault hosts
* Removed wrong when condition in create etcd role vault tasks.
* Adding yaml linter to ci check
* Minor linting fixes from yamllint
* Changing CI to install python pkgs from requirements.txt
- adding in a secondary requirements.txt for tests
- moving yamllint to tests requirements
* Added custom ips to etcd vault distributed certificates
* Added custom ips to kube-master vault distributed certificates
* Added comment about issue_cert_copy_ca var in vault/issue_cert role file
* Generate kube-proxy, controller-manager and scheduler certificates by vault
* Revert "Disable vault from CI (#1546)"
This reverts commit 781f31d2b8.
* Fixed upgrade cluster with vault cert manager
* Remove vault dir in reset playbook
This does not address per-node certs and scheduler/proxy/controller-manager
component certs which are now required. This should be handled in a
follow-up patch.
