--------------
K8s components require a loadbalancer to access the apiservers via a reverse
proxy. A kube-proxy does not support multiple apiservers for the time being so
proxy. Kargo includes support for an nginx-based proxy that resides on each
non-master Kubernetes node. This is referred to as localhost loadbalancing. It
is less efficient than a dedicated load balancer because it creates extra
health checks on the Kubernetes apiserver, but is more practical for scenarios
where an external LB or virtual IP management is inconvenient.
This option is configured by the variable `loadbalancer_apiserver_localhost`.
you will need to configure your own loadbalancer to achieve HA. Note that
deploying a loadbalancer is up to a user and is not covered by ansible roles
in Kargo. By default, it only configures a non-HA endpoint, which points to
the `access_ip` or IP address of the first server node in the `kube-master`
group. It can also configure clients to use endpoints for a given loadbalancer
type.
type. The following diagram shows how traffic to the apiserver is directed.
A loadbalancer (LB) may be an external or internal one. An external LB
![Image](figures/loadbalancer_localhost.png?raw=true)
Note: Kubernetes master nodes still use insecure localhost access because
there are bugs in Kubernetes <1.5.0 in using TLS auth on master role
services. This makes backends receiving unencrypted traffic and may be a
security issue when interconnecting different nodes, or maybe not, if those
belong to the isolated management network without external access.
A user may opt to use an external loadbalancer (LB) instead. An external LB
provides access for external clients, while the internal LB accepts client
connections only to the localhost, similarly to the etcd-proxy HA endpoints.
Given a frontend `VIP` address and `IP1, IP2` addresses of backends, here is

is out of scope of this doc. Specifying an external LB overrides any internal
localhost LB configuration.
The internal LB may be the case if you do not want to operate a VIP management
HA stack and require no external and no secure access to the K8s API. The group
var `loadbalancer_apiserver_localhost` (defaults to `false`) controls that
deployment layout. When enabled, it is expected each node in the `k8s-cluster`
group to run a loadbalancer that listens the localhost frontend and has all
of the apiservers as backends. Here is an example configuration for a HAProxy
service acting as an internal LB:
```
listen kubernetes-apiserver-http
bind localhost:8080
mode tcp
timeout client 3h
timeout server 3h
server master1 <IP1>:8080
server master2 <IP2>:8080
balance leastconn
```
And the corresponding example global vars config:
```
loadbalancer_apiserver_localhost: true
```
This var overrides an external LB configuration, if any. Note that for this
example, the `kubernetes-apiserver-http` endpoint has backends receiving
unencrypted traffic, which may be a security issue when interconnecting
different nodes, or may be not, if those belong to the isolated management
network without external access.
In order to achieve HA for HAProxy instances, those must be running on the
each node in the `k8s-cluster` group as well, but require no VIP, thus
no VIP management.
Note: In order to achieve HA for HAProxy instances, those must be running on

Access endpoints are evaluated automagically, as the following:

|------------------------------|---------------|---------------------|
| Local LB (overrides ext) | http://lc:p | http://lc:p |
| Local LB | http://lc:p | https://lc:sp |
| External LB, no internal | https://lb:lp | https://lb:lp |
| No ext/int LB (default) | http://lc:p | https://m[0].aip:sp |

Kargo's roadmap
=================
### Kubeadm
- Propose kubeadm as an option in order to setup the kubernetes cluster.
That would probably improve deployment speed and certs management [#553](https://github.com/kubespray/kargo/issues/553)
### Self deployment (pull-mode) [#320](https://github.com/kubespray/kargo/issues/320)
- the playbook would install and configure docker/rkt and the etcd cluster
- the following data would be inserted into etcd: certs,tokens,users,inventory,group_vars.
