-- The list of available docker version is 18.09, 19.03 and 20.10. The recommended docker version is 20.10. The kubelet might break on docker's non-standard version numbering (it no longer uses semantic versioning). To ensure auto-updates don't break your cluster look into e.g. yum versionlock plugin or apt pin).

The kubelet might break on docker's non-standard version numbering (it no longer uses semantic versioning). To ensure auto-updates don't break your cluster look into e.g. yum versionlock plugin or apt pin).
 - The cri-o version should be aligned with the respective kubernetes version (i.e. kube_version=1.20.x, crio_version=1.20)
 
 ## Requirements
 
-- **Minimum required version of Kubernetes is v1.20**
+- **Minimum required version of Kubernetes is v1.19**
 - **Ansible v2.9.x, Jinja 2.11+ and python-netaddr is installed on the machine that will run Ansible commands, Ansible 2.10.x is experimentally supported for now**
 - The target servers must have **access to the Internet** in order to pull docker images. Otherwise, additional configuration is required (See [Offline Environment](docs/offline-environment.md))
 - The target servers are configured to allow **IPv4 forwarding**.

-
-## Overview
-
-The setup looks like following
-
-```text

-|        +--------------+  |
-+--------------------------+
-```
-
-The nodes uses a private network for node to node communication and a public interface for all external communication.
-
-## Requirements
-
-* Terraform 0.14.0 or newer
-
-## Quickstart
-
-NOTE: Assumes you are at the root of the kubespray repo.
-
-For authentication in your cluster you can use the environment variables.
-
-```bash
-export HCLOUD_TOKEN=api-token
-```
-
-Copy the cluster configuration file.
-
-```bash
-CLUSTER=my-hetzner-cluster
-cp -r inventory/sample inventory/$CLUSTER
-cp contrib/terraform/hetzner/default.tfvars inventory/$CLUSTER/
-cd inventory/$CLUSTER
-```
-
-Edit `default.tfvars` to match your requirement.
-
-Run Terraform to create the infrastructure.
-
-```bash
-terraform init ../../contrib/terraform/hetzner
-terraform apply --var-file default.tfvars ../../contrib/terraform/hetzner/
-```
-
-You should now have a inventory file named `inventory.ini` that you can use with kubespray.
-You can use the inventory file with kubespray to set up a cluster.
-
-It is a good idea to check that you have basic SSH connectivity to the nodes. You can do that by:
-
-```bash
-ansible -i inventory.ini -m ping all
-```
-
-You can setup Kubernetes with kubespray using the generated inventory:
-
-```bash
-ansible-playbook -i inventory.ini ../../cluster.yml -b -v
-```
-
-## Cloud controller
-
-For better support with the cloud you can install the [hcloud cloud controller](https://github.com/hetznercloud/hcloud-cloud-controller-manager) and [CSI driver](https://github.com/hetznercloud/csi-driver).
-
-Please read the instructions in both repos on how to install it.
-
-## Teardown
-
-You can teardown your infrastructure using the following Terraform command:
-
-```bash
-terraform destroy --var-file default.tfvars ../../contrib/terraform/hetzner
-```
-
-## Variables
-
-* `prefix`: Prefix to add to all resources, if set to "" don't set any prefix
-* `ssh_public_keys`: List of public SSH keys to install on all machines
-* `zone`: The zone where to run the cluster
-* `machines`: Machines to provision. Key of this object will be used as the name of the machine
-  * `node_type`: The role of this node *(master|worker)*
-  * `size`: Size of the VM
-  * `image`: The image to use for the VM
-* `ssh_whitelist`: List of IP ranges (CIDR) that will be allowed to ssh to the nodes

+# Ambassador
+
+The [Ambassador API Gateway](https://github.com/datawire/ambassador) provides all the functionality of a traditional ingress controller
+(e.g., path-based routing) while exposing many additional capabilities such as authentication,
+URL rewriting, CORS, rate limiting, and automatic metrics collection.
+
+## Installation
+
+### Configuration
+
+* `ingress_ambassador_namespace` (default `ambassador`): namespace for installing Ambassador.
+* `ingress_ambassador_update_window` (default `0 0 * * SUN`): _crontab_-like expression
+  for specifying when the Operator should try to update the Ambassador API Gateway.
+* `ingress_ambassador_version` (default: `*`): SemVer rule for versions allowed for
+  installation/updates.
+* `ingress_ambassador_secure_port` (default: 443): HTTPS port to listen at.
+* `ingress_ambassador_insecure_port` (default: 80): HTTP port to listen at.
+
+### Ambassador Operator
+
+This Ambassador addon deploys the Ambassador Operator, which in turn will install
+the [Ambassador API Gateway](https://github.com/datawire/ambassador) in
+a Kubernetes cluster.
+
+The Ambassador Operator is a Kubernetes Operator that controls Ambassador's complete lifecycle
+in your cluster, automating many of the repeatable tasks you would otherwise have to perform
+yourself.  Once installed, the Operator will complete installations and seamlessly upgrade to new
+versions of Ambassador as they become available.
+
+## Usage
+
+The following example creates simple http-echo services and an `Ingress` object
+to route to these services.
+
+Note well that the [Ambassador API Gateway](https://github.com/datawire/ambassador) will automatically load balance `Ingress` resources
+that include the annotation `kubernetes.io/ingress.class=ambassador`. All the other
+resources will be just ignored.
+
+```yaml
+kind: Pod
+apiVersion: v1
+metadata:
+  name: foo-app
+  labels:
+    app: foo
+spec:
+  containers:
+  - name: foo-app
+    image: hashicorp/http-echo
+    args:
+    - "-text=foo"
+---
+kind: Service
+apiVersion: v1
+metadata:
+  name: foo-service
+spec:
+  selector:
+    app: foo
+  ports:
+  # Default port used by the image
+  - port: 5678
+---
+apiVersion: extensions/v1beta1
+kind: Ingress
+metadata:
+  name: example-ingress
+  annotations:
+    kubernetes.io/ingress.class: ambassador
+spec:
+  rules:
+  - http:
+      paths:
+      - path: /foo
+        backend:
+          serviceName: foo-service
+          servicePort: 5678
+```
+
+Now you can test that the ingress is working with curl:
+
+```console
+$ export AMB_IP=$(kubectl get service ambassador -n ambassador -o 'go-template={{range .status.loadBalancer.ingress}}{{print .ip "\n"}}{{end}}')
+$ curl $AMB_IP/foo
+foo
+```

-two projects which are now joined under the Ansible umbrella.
-
-Ansible-base (2.10.x branch) will contain just the ansible language implementation while
-ansible modules that were previously bundled into a single repository will be part of the
-ansible 3.x package. Pleasee see [this blog post](https://blog.while-true-do.io/ansible-release-3-0-0/)
-that explains in detail the need and the evolution plan.
-
-**Note:** this change means that ansible virtual envs cannot be upgraded with `pip install -U`.
-You first need to uninstall your old ansible (pre 2.10) version and install the new one.
-
-```ShellSession
-pip uninstall ansible
-cd kubespray/
-pip install -U .
-```
-
-**Note:** some changes needed to support ansible 2.10+ are not backwards compatible with 2.9
-Kubespray needs to evolve and keep pace with upstream ansible and will be forced to eventually
-drop 2.9 support. Kubespray CIs use only the ansible version specified in the `requirements.txt`
-and while the `ansible_version.yml` may allow older versions to be used, these are not
-exercised in the CI and compatibility is not guaranteed.

 ## Config encapsulation for cross server traffic
 
 Calico supports two types of encapsulation: [VXLAN and IP in IP](https://docs.projectcalico.org/v3.11/networking/vxlan-ipip). VXLAN is supported in some environments where IP in IP is not (for example, Azure).
@@ -228,19 +219,6 @@ calico_vxlan_mode: 'Never'
 
 If you use VXLAN mode, BGP networking is not required. You can disable BGP to reduce the moving parts in your cluster by `calico_network_backend: vxlan`
 
-## Configuring interface MTU
-
-This is an advanced topic and should usually not be modified unless you know exactly what you are doing. Calico is smart enough to deal with the defaults and calculate the proper MTU. If you do need to set up a custom MTU you can change `calico_veth_mtu` as follows:
-
-* If Wireguard is enabled, subtract 60 from your network MTU (i.e. 1500-60=1440)
-* If using VXLAN or BPF mode is enabled, subtract 50 from your network MTU (i.e. 1500-50=1450)
-* If using IPIP, subtract 20 from your network MTU (i.e. 1500-20=1480)
-* if not using any encapsulation, set to your network MTU (i.e. 1500 or 9000)
-
-```yaml
-calico_veth_mtu: 1440
-```
-
 ## Cloud providers configuration
 
 Please refer to the official documentation, for example [GCE configuration](http://docs.projectcalico.org/v1.5/getting-started/docker/installation/gce) requires a security rule for calico ip-ip tunnels. Note, calico is always configured with ``calico_ipip_mode: Always`` if the cloud provider was defined.

-## eBPF Support
-
-Calico supports eBPF for its data plane see [an introduction to the Calico eBPF Dataplane](https://www.projectcalico.org/introducing-the-calico-ebpf-dataplane/) for further information.
-
-Note that it is advisable to always use the latest version of Calico when using the eBPF dataplane.
-
-### Enabling eBPF support
-
-To enable the eBPF dataplane support ensure you add the following to your inventory. Note that the `kube-proxy` is incompatible with running Calico in eBPF mode and the kube-proxy should be removed from the system.
-
-```yaml
-calico_bpf_enabled: true
-```
-
-**NOTE:** there is known incompatibility in using the `kernel-kvm` kernel package on Ubuntu OSes because it is missing support for `CONFIG_NET_SCHED` which is a requirement for Calico eBPF support. When using Calico eBPF with Ubuntu ensure you run the `-generic` kernel.
-
-### Cleaning up after kube-proxy
-
-Calico node cannot clean up after kube-proxy has run in ipvs mode. If you are converting an existing cluster to eBPF you will need to ensure the `kube-proxy` DaemonSet is deleted and that ipvs rules are cleaned.
-
-To check that kube-proxy was running in ipvs mode:
-
-```ShellSession
-# ipvsadm -l
-```
-
-To clean up any ipvs leftovers:
-
-```ShellSession
-# ipvsadm -C
-```
-
-### Calico access to the kube-api
-
-Calico node, typha and kube-controllers need to be able to talk to the kubernetes API. Please reference the [Enabling eBPF Calico Docs](https://docs.projectcalico.org/maintenance/ebpf/enabling-bpf) for guidelines on how to do this.
-
-Kubespray sets up the `kubernetes-services-endpoint` configmap based on the contents of the `loadbalancer_apiserver` inventory variable documented in [HA Mode](/docs/ha-mode.md).
-
-If no external loadbalancer is used, Calico eBPF can also use the localhost loadbalancer option. In this case Calico Automatic Host Endpoints need to be enabled to allow services like `coredns` and `metrics-server` to communicate with the kubernetes host endpoint. See [this blog post](https://www.projectcalico.org/securing-kubernetes-nodes-with-calico-automatic-host-endpoints/) on enabling automatic host endpoints.
-
-```yaml
-loadbalancer_apiserver_localhost: true
-use_localhost_as_kubeapi_loadbalancer: true
-```
-
-### Tunneled versus Direct Server Return
-
-By default Calico usese Tunneled service mode but it can use direct server return (DSR) in order to optimize the return path for a service.
-
-To configure DSR:
-
-```yaml
-calico_bpf_service_mode: "DSR"
-```
-
-### eBPF Logging and Troubleshooting
-
-In order to enable Calico eBPF mode logging:
-
-```yaml
-calico_bpf_log_level: "Debug"
-```
-
-To view the logs you need to use the `tc` command to read the kernel trace buffer:
-
-```ShellSession
-tc exec bpf debug
-```
-
-Please see [Calico eBPF troubleshooting guide](https://docs.projectcalico.org/maintenance/troubleshoot/troubleshoot-ebpf#ebpf-program-debug-logs).
-
-## Wireguard Encryption
-
-Calico supports using Wireguard for encryption. Please see the docs on [encryptiong cluster pod traffic](https://docs.projectcalico.org/security/encrypt-cluster-pod-traffic).
-
-To enable wireguard support:
-
-```yaml
-calico_wireguard_enabled: true
-```
-
-The following OSes will require enabling the EPEL repo in order to bring in wireguard tools:
-
-* CentOS 7 & 8
-* AlmaLinux 8
-* Rocky Linux 8
-* Amazon Linux 2
-
-```yaml
-epel_enabled: true
-```
