AWS
|
||||
===============
|
||||
|
||||
To deploy kubespray on [AWS](https://aws.amazon.com/) uncomment the `cloud_provider` option in `group_vars/all.yml` and set it to `'aws'`.
|
||||
|
||||
Prior to creating your instances, you **must** ensure that you have created IAM roles and policies for both "kubernetes-master" and "kubernetes-node". You can find the IAM policies [here](https://github.com/kubernetes/kubernetes/tree/master/cluster/aws/templates/iam). See the [IAM Documentation](https://aws.amazon.com/documentation/iam/) if guidance is needed on how to set these up. When you bring your instances online, associate them with the respective IAM role. Nodes that are only to be used for Etcd do not need a role.
|
||||
|
||||
The next step is to make sure the hostnames in your `inventory` file are identical to your internal hostnames in AWS. This may look something like `ip-111-222-333-444.us-west-2.compute.internal`. You can then specify how Ansible connects to these instances with `ansible_ssh_host` and `ansible_ssh_user`.
|
||||
|
||||
You can now create your cluster!

K8s DNS stack by Kargo
|
||||
======================
|
||||
|
||||
Kargo configures a [Kubernetes DNS](http://kubernetes.io/docs/admin/dns/)
|
||||
[cluster add-on](http://releases.k8s.io/master/cluster/addons/README.md)
|
||||
to serve as an authoritative DNS server for a given ``dns_domain`` and its
|
||||
``svc, default.svc`` default subdomains (a total of ``ndots: 5`` max levels).
|
||||
|
||||
Note, additional search (sub)domains may be defined in the ``searchdomains``
|
||||
and ``ndots`` vars. And additional recursive DNS resolvers in the `` upstream_dns_servers``,
|
||||
``nameservers`` vars. Intranet DNS resolvers should be specified in the first
|
||||
place, followed by external resolvers, for example:
|
||||
|
||||
```
|
||||
skip_dnsmasq: true
|
||||
nameservers: [8.8.8.8]
|
||||
upstream_dns_servers: [172.18.32.6]
|
||||
```
|
||||
or
|
||||
```
|
||||
skip_dnsmasq: false
|
||||
upstream_dns_servers: [172.18.32.6, 172.18.32.7, 8.8.8.8, 8.8.8.4]
|
||||
```
|
||||
The vars are explained below as well.
|
||||
|
||||
DNS configuration details
|
||||
-------------------------
|
||||
|
||||
Here is an approximate picture of how DNS things working and
|
||||
being configured by Kargo ansible playbooks:
|
||||
|
||||
|
||||
|
||||
Note that an additional dnsmasq daemon set is installed by Kargo
|
||||
by default. Kubelet will configure DNS base of all pods to use the
|
||||
given dnsmasq cluster IP, which is defined via the ``dns_server`` var.
|
||||
The dnsmasq forwards requests for a given cluster ``dns_domain`` to
|
||||
Kubedns's SkyDns service. The SkyDns server is configured to be an
|
||||
authoritative DNS server for the given cluser domain (and its subdomains
|
||||
up to ``ndots:5`` depth). Note: you should scale its replication controller
|
||||
up, if SkyDns chokes. These two layered DNS forwarders provide HA for the
|
||||
DNS cluster IP endpoint, which is a critical moving part for Kubernetes apps.
|
||||
|
||||
Nameservers are as well configured in the hosts' ``/etc/resolv.conf`` files,
|
||||
as the given DNS cluster IP merged with ``nameservers`` values. While the
|
||||
DNS cluster IP merged with the ``upstream_dns_servers`` defines additional
|
||||
nameservers for the aforementioned nsmasq daemon set running on all hosts.
|
||||
This mitigates existing Linux limitation of max 3 nameservers in the
|
||||
``/etc/resolv.conf`` and also brings an additional caching layer for the
|
||||
clustered DNS services.
|
||||
|
||||
You can skip the dnsmasq daemon set install steps by setting the
|
||||
``skip_dnsmasq: true``. This may be the case, if you're fine with
|
||||
the nameservers limitation. Sadly, there is no way to work around the
|
||||
search domain limitations of a 256 chars and 6 domains. Thus, you can
|
||||
use the ``searchdomains`` var to define no more than a three custom domains.
|
||||
Remaining three slots are reserved for K8s cluster default subdomains.
|
||||
|
||||
When dnsmasq skipped, Kargo redefines the DNS cluster IP to point directly
|
||||
to SkyDns cluster IP ``skydns_server`` and configures Kubelet's
|
||||
``--dns_cluster`` to use that IP as well. While this greatly simplifies
|
||||
things, it comes by the price of limited nameservers though. As you know now,
|
||||
the DNS cluster IP takes a slot in the ``/etc/resolv.conf``, thus you can
|
||||
specify no more than a two nameservers for infra and/or external use.
|
||||
Those may be specified either in ``nameservers`` or ``upstream_dns_servers``
|
||||
and will be merged together with the ``skydns_server`` IP into the hots'
|
||||
``/etc/resolv.conf``.
|
||||
|
||||
Limitations
|
||||
-----------
|
||||
|
||||
* Kargo has yet ways to configure Kubedns addon to forward requests SkyDns can
|
||||
not answer with authority to arbitrary recursive resolvers. This task is left
|
||||
for future. See [official SkyDns docs](https://github.com/skynetservices/skydns)
|
||||
for details.
|
||||
|
||||
* There is
|
||||
[no way to specify a custom value](https://github.com/kubernetes/kubernetes/issues/33554)
|
||||
for the SkyDNS ``ndots`` param via an
|
||||
[option for KubeDNS](https://github.com/kubernetes/kubernetes/blob/master/cmd/kube-dns/app/options/options.go)
|
||||
add-on, while SkyDNS supports it though. Thus, DNS SRV records may not work
|
||||
as expected as they require the ``ndots:7``.
|
||||
|
||||
* the ``searchdomains`` have a limitation of a 6 names and 256 chars
|
||||
length. Due to default ``svc, default.svc`` subdomains, the actual
|
||||
limits are a 4 names and 239 chars respectively.
|
||||
|
||||
* the ``nameservers`` have a limitation of a 3 servers, although there
|
||||
is a way to mitigate that with the ``upstream_dns_servers``,
|
||||
see below. Anyway, the ``nameservers`` can take no more than a two
|
||||
custom DNS servers because of one slot is reserved for a Kubernetes
|
||||
cluster needs.

HA endpoints for K8s
|
||||
====================
|
||||
|
||||
The following components require a highly available endpoints:
|
||||
* etcd cluster,
|
||||
* kube-apiserver service instances.
|
||||
|
||||
The former provides the
|
||||
[etcd-proxy](https://coreos.com/etcd/docs/latest/proxy.html) service to access
|
||||
the cluster members in HA fashion.
|
||||
|
||||
The latter relies on a 3rd side reverse proxies, like Nginx or HAProxy, to
|
||||
achieve the same goal.
|
||||
|
||||
Etcd
|
||||
----
|
||||
|
||||
Etcd proxies are deployed on each node in the `k8s-cluster` group. A proxy is
|
||||
a separate etcd process. It has a `localhost:2379` frontend and all of the etcd
|
||||
cluster members as backends. Note that the `access_ip` is used as the backend
|
||||
IP, if specified. Frontend endpoints cannot be accessed externally as they are
|
||||
bound to a localhost only.
|
||||
|
||||
The `etcd_access_endpoint` fact provides an access pattern for clients. And the
|
||||
`etcd_multiaccess` (defaults to `false`) group var controlls that behavior.
|
||||
When enabled, it makes deployed components to access the etcd cluster members
|
||||
directly: `http://ip1:2379, http://ip2:2379,...`. This mode assumes the clients
|
||||
do a loadbalancing and handle HA for connections. Note, a pod definition of a
|
||||
flannel networking plugin always uses a single `--etcd-server` endpoint!
|
||||
|
||||
|
||||
Kube-apiserver
|
||||
--------------
|
||||
|
||||
K8s components require a loadbalancer to access the apiservers via a reverse
|
||||
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. The following diagram shows how traffic to the apiserver is directed.
|
||||
|
||||
|
||||
|
||||
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
|
||||
an example configuration for a HAProxy service acting as an external LB:
|
||||
```
|
||||
listen kubernetes-apiserver-https
|
||||
bind <VIP>:8383
|
||||
option ssl-hello-chk
|
||||
mode tcp
|
||||
timeout client 3h
|
||||
timeout server 3h
|
||||
server master1 <IP1>:443
|
||||
server master2 <IP2>:443
|
||||
balance roundrobin
|
||||
```
|
||||
|
||||
And the corresponding example global vars config:
|
||||
```
|
||||
apiserver_loadbalancer_domain_name: "lb-apiserver.kubernetes.local"
|
||||
loadbalancer_apiserver:
|
||||
address: <VIP>
|
||||
port: 8383
|
||||
```
|
||||
|
||||
This domain name, or default "lb-apiserver.kubernetes.local", will be inserted
|
||||
into the `/etc/hosts` file of all servers in the `k8s-cluster` group. Note that
|
||||
the HAProxy service should as well be HA and requires a VIP management, which
|
||||
is out of scope of this doc. Specifying an external LB overrides any internal
|
||||
localhost LB configuration.
|
||||
|
||||
Note: 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.
|
||||
|
||||
Access endpoints are evaluated automagically, as the following:
|
||||
|
||||
| Endpoint type | kube-master | non-master |
|
||||
|------------------------------|---------------|---------------------|
|
||||
| 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 |
|
||||
|
||||
Where:
|
||||
* `m[0]` - the first node in the `kube-master` group;
|
||||
* `lb` - LB FQDN, `apiserver_loadbalancer_domain_name`;
|
||||
* `lc` - localhost;
|
||||
* `p` - insecure port, `kube_apiserver_insecure_port`
|
||||
* `sp` - secure port, `kube_apiserver_port`;
|
||||
* `lp` - LB port, `loadbalancer_apiserver.port`, defers to the secure port;
|
||||
* `ip` - the node IP, defers to the ansible IP;
|
||||
* `aip` - `access_ip`, defers to the ip.

Large deployments of K8s
|
||||
========================
|
||||
|
||||
For a large scaled deployments, consider the following configuration changes:
|
||||
|
||||
* Tune [ansible settings](http://docs.ansible.com/ansible/intro_configuration.html)
|
||||
for `forks` and `timeout` vars to fit large numbers of nodes being deployed.
|
||||
|
||||
* Override containers' `foo_image_repo` vars to point to intranet registry.
|
||||
|
||||
* Override the ``download_run_once: true`` to download binaries and container
|
||||
images only once then push to nodes in batches.
|
||||
|
||||
* Adjust the `retry_stagger` global var as appropriate. It should provide sane
|
||||
load on a delegate (the first K8s master node) then retrying failed
|
||||
push or download operations.
|
||||
|
||||
For example, when deploying 200 nodes, you may want to run ansible with
|
||||
``--forks=50``, ``--timeout=600`` and define the ``retry_stagger: 60``.

### Kubeadm
|
