Upgrade Kubernetes to V1.11.2
The kubeadm configuration file version has been upgraded from v1alpha1 to v1alpha2
Add bootstrap kubeadm-config.yaml with external etcd
* 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
The current way to setup the etc cluster is messy and buggy.
- It checks for cluster is healthy before the cluster is even created.
- The unit files are started on handlers, not in the task, so you mess with "flush handlers".
- The join_member.yml is not used.
- etcd events cluster is not configured for kubeadm
- remove duplicate runs between running the role on etcd nodes and k8s nodes
* Added option for encrypting secrets to etcd
* Fix keylength to 32
* Forgot the default
* Rename secrets.yaml to secrets_encryption.yaml
* Fix static path for secrets file to use ansible variable
* Rename secrets.yaml.j2 to secrets_encryption.yaml.j2
* Base64 encode the token
* Fixed merge error
* Changed path to credentials dir
* Update path to secrets file which is now readable inside the apiserver container. Set better file permissions
* Add encryption option to k8s-cluster.yml
Setting the following:
```
kube_kubeadm_controller_extra_args:
address: 0.0.0.0
terminated-pod-gc-threshold: "100"
```
Results in `terminated-pod-gc-threshold: 100` in the kubeadm config file. But it has to be a string to work.
to the API server configuration.
This solves the problem where if you have non-resolvable node names,
and try to scale the server by adding new nodes, kubectl commands
start to fail for newly added nodes, giving a TCP timeout error when
trying to resolve the node hostname against a public DNS.
* Added cilium support
* Fix typo in debian test config
* Remove empty lines
* Changed cilium version from <latest> to <v1.0.0-rc3>
* Add missing changes for cilium
* Add cilium to CI pipeline
* Fix wrong file name
* Check kernel version for cilium
* fixed ci error
* fixed cilium-ds.j2 template
* added waiting for cilium pods to run
* Fixed missing EOF
* Fixed trailing spaces
* Fixed trailing spaces
* Fixed trailing spaces
* Fixed too many blank lines
* Updated tolerations,annotations in cilium DS template
* Set cilium_version to iptables-1.9 to see if bug is fixed in CI
* Update cilium image tag to v1.0.0-rc4
* Update Cilium test case CI vars filenames
* Add optional prometheus flag, adjust initial readiness delay
* Update README.md with cilium info
Update checksum for kubeadm
Use v1.9.0 kubeadm params
Include hash of ca.crt for kubeadm join
Update tag for testing upgrades
Add workaround for testing upgrades
Remove scale CI scenarios because of slow inventory parsing
in ansible 2.4.x.
Change region for tests to us-central1 to
improve ansible performance
This allows `kube_apiserver_insecure_port` to be set to 0 (disabled).
Rework of #1937 with kubeadm support
Also, fixed an issue in `kubeadm-migrate-certs` where the old apiserver cert was copied as the kubeadm key
* Allow setting --bind-address for apiserver hyperkube
This is required if you wish to configure a loadbalancer (e.g haproxy)
running on the master nodes without choosing a different port for the
vip from that used by the API - in this case you need the API to bind to
a specific interface, then haproxy can bind the same port on the VIP:
root@overcloud-controller-0 ~]# netstat -taupen | grep 6443
tcp 0 0 192.168.24.6:6443 0.0.0.0:* LISTEN 0 680613 134504/haproxy
tcp 0 0 192.168.24.16:6443 0.0.0.0:* LISTEN 0 653329 131423/hyperkube
tcp 0 0 192.168.24.16:6443 192.168.24.16:58404 ESTABLISHED 0 652991 131423/hyperkube
tcp 0 0 192.168.24.16:58404 192.168.24.16:6443 ESTABLISHED 0 652986 131423/hyperkube
This can be achieved e.g via:
kube_apiserver_bind_address: 192.168.24.16
* Address code review feedback
* Update kube-apiserver.manifest.j2
