77fc14db71 Workaround target pool issue by listing instances as zone/name
* Instances can be listed by zone/name or self_link URL, but the
provider desires they be in zone/name form, which causes a diff

67e3d2b86e docs: GCE network bandwidth is excellent, even btw zones
* Remove performance note that the GCE vs AWS network performance
is not an equal comparison. On both platforms, workers now span the
(availability) zones of a region.
* Testing host-to-host and pod-to-pod network bandwidth between nodes
(now located in different zones) showed no reduction in bandwidth

26a291aef4 Remove controller_preemptible option on Google Cloud
* Controller preemption is not safe or covered in documentation. Delete
the option, the variable is a holdover from old experiments

2017-11-04 12:59:19 -07:00
251a14519f Fix typo in internal template variable name
* ssh_authorized_keys should be ssh_authorized_key to match the user
facing variable which only allows a single SSH authorized key
2017-11-04 12:59:19 -07:00
6300383b43 Change worker managed instance group to span zones in region
* Change Google Cloud module to require the `region` variable
* Workers are created in random zones within the given region
* Tolerate Google Cloud zone failures or capacity issues
* If workers are preempted (if enabled), replacement instances can
be drawn from any zone in the region, which should avoid scheduling
issues that were possible before if a single zone aggressively
preempts instances (presumably due to Google Cloud capacity)

a97df839ea google-cloud: Set disk.device_name to match API default
* Terraform provider "google" plugin releases leave the disk
device_name as "" by default. Recently the API has started to
set a default name "persistent-disk-0". Plan and apply show
all instance groups need to be recreated to "fix" the name
* Impact: Controller and worker instance groups are deleted
and recreated, deleting data on controllers and bringing
down clusters
* Fix: Explicitly set the disk_name to persistent-disk-0 so
that terraform finds no diff needs to be applied.

2017-09-24 20:18:22 -07:00
1b5caef4c1 Add Wants=rpc-statd.service to Kubelet
* Mounting NFS exports as volumes from some NFS servers fails because
the kubelet isn't starting rpc-statd as expected. Describing pods
that are stuck creating shows rpc.statd is required for remote locking
* Starting rpc-statd.service resolves the issue and all NFS mounts
seem to be working.
* Recommended approach https://github.com/coreos/bugs/issues/2074

bca96bb124 bare-metal: Ues Terraform templating for Container Linux configs
* Template bare-metal Container Linux configs with Terraform's
(limited) template_file module. This allows rendering problems
to be identified during `terraform plan` and is favored over
using the Matchbox templating feature when the configs are
served to PXE booting nodes.
* Writes a Matchbox profile for each machine, which will be served
as-is. The effect is the same, each node gets provisioned with its
own Container Linux config.

# Typhoon
Typhoon is a minimal and free Kubernetes distribution.
* Minimal, stable base Kubernetes distribution
* Declarative infrastructure and configuration
* Free (freedom and cost) and privacy-respecting
* Practical for labs, datacenters, and clouds
Typhoon distributes upstream Kubernetes, architectural conventions, and cluster addons, much like a GNU/Linux distribution provides the Linux kernel and userspace components.
## Features
* Kubernetes v1.8.3 (upstream, via [kubernetes-incubator/bootkube](https://github.com/kubernetes-incubator/bootkube))
* Single or multi-master, workloads isolated on workers, [Calico](https://www.projectcalico.org/) or [flannel](https://github.com/coreos/flannel) networking
* On-cluster etcd with TLS, [RBAC](https://kubernetes.io/docs/admin/authorization/rbac/)-enabled, [network policy](https://kubernetes.io/docs/concepts/services-networking/network-policies/)
* Ready for Ingress, Dashboards, Metrics, and other optional [addons](https://typhoon.psdn.io/addons/overview/)
## Docs
Please see the [official docs](https://typhoon.psdn.io) and the AWS [tutorial](https://typhoon.psdn.io/aws/).

# Typhoon
Typhoon is a minimal and free Kubernetes distribution.
* Minimal, stable base Kubernetes distribution
* Declarative infrastructure and configuration
* Free (freedom and cost) and privacy-respecting
* Practical for labs, datacenters, and clouds
Typhoon distributes upstream Kubernetes, architectural conventions, and cluster addons, much like a GNU/Linux distribution provides the Linux kernel and userspace components.
## Features
* Kubernetes v1.8.3 (upstream, via [kubernetes-incubator/bootkube](https://github.com/kubernetes-incubator/bootkube))
* Single or multi-master, workloads isolated on workers, [Calico](https://www.projectcalico.org/) or [flannel](https://github.com/coreos/flannel) networking
* On-cluster etcd with TLS, [RBAC](https://kubernetes.io/docs/admin/authorization/rbac/)-enabled, [network policy](https://kubernetes.io/docs/concepts/services-networking/network-policies/)
* Ready for Ingress, Dashboards, Metrics, and other optional [addons](https://typhoon.psdn.io/addons/overview/)
## Docs
Please see the [official docs](https://typhoon.psdn.io) and the bare-metal [tutorial](https://typhoon.psdn.io/bare-metal/).

# Typhoon
Typhoon is a minimal and free Kubernetes distribution.
* Minimal, stable base Kubernetes distribution
* Declarative infrastructure and configuration
* Free (freedom and cost) and privacy-respecting
* Practical for labs, datacenters, and clouds
Typhoon distributes upstream Kubernetes, architectural conventions, and cluster addons, much like a GNU/Linux distribution provides the Linux kernel and userspace components.
## Features
* Kubernetes v1.8.3 (upstream, via [kubernetes-incubator/bootkube](https://github.com/kubernetes-incubator/bootkube))
* Single or multi-master, workloads isolated on workers, [Calico](https://www.projectcalico.org/) or [flannel](https://github.com/coreos/flannel) networking
* On-cluster etcd with TLS, [RBAC](https://kubernetes.io/docs/admin/authorization/rbac/)-enabled, [network policy](https://kubernetes.io/docs/concepts/services-networking/network-policies/)
* Ready for Ingress, Dashboards, Metrics, and other optional [addons](https://typhoon.psdn.io/addons/overview/)
## Docs
Please see the [official docs](https://typhoon.psdn.io) and the Digital Ocean [tutorial](https://typhoon.psdn.io/digital-ocean/).

# Ingress Controller
# Nginx Ingress Controller
!!! bug "In Progress"
These docs haven't been moved over yet.
Nginx Ingress controller pods accept and demultiplex HTTP, HTTPS, TCP, or UDP traffic to backend services. Ingress controllers watch the Kubernetes API for Ingress resources and update their configuration accordingly. Ingress resources for HTTP(S) applications support virtual hosts (FQDNs), path rules, TLS termination, and SNI.
## AWS
On AWS, an elastic load balancer distributes traffic across worker nodes (i.e. an auto-scaling group) running an Ingress controller deployment on host ports 80 and 443. Firewall rules allow traffic to ports 80 and 443. Health check rules ensure only workers with a health Ingress controller receive traffic.
Create the Ingress controller deployment, service, RBAC roles, RBAC bindings, default backend, and namespace.
```
kubectl apply -R -f addons/nginx-ingress/aws
```
For each application, add a DNS CNAME resolving to the ELB's DNS record.
```
app1.example.com -> tempest-ingress.123456.us-west2.elb.amazonaws.com
aap2.example.com -> tempest-ingress.123456.us-west2.elb.amazonaws.com
app3.example.com -> tempest-ingress.123456.us-west2.elb.amazonaws.com
```
Find the ELB's DNS name through the console or use the Typhoon module's output `ingress_dns_name`. For example, you might use Terraform to manage a Google Cloud DNS record:
```tf
resource "google_dns_record_set" "some-application" {
# DNS zone name
managed_zone = "example-zone"
# DNS record
name = "app.example.com."
type = "CNAME"
ttl = 300
rrdatas = ["${module.aws-tempest.ingress_dns_name}."]
}
```
## Digital Ocean
On Digital Ocean, a DNS A record (e.g. `nemo-workers.example.com`) resolves to each worker[^1] running an Ingress controller DaemonSet on host ports 80 and 443. Firewall rules allow IPv4 and IPv6 traffic to ports 80 and 443.
Create the Ingress controller daemonset, service, RBAC roles, RBAC bindings, default backend, and namespace.
```
kubectl apply -R -f addons/nginx-ingress/digital-ocean
```
For each application, add a CNAME record resolving to the worker(s) DNS record. Use the Typhoon module's output `workers_dns` to find the worker DNS value. For example, you might use Terraform to manage a Google Cloud DNS record:
```tf
resource "google_dns_record_set" "some-application" {
# DNS zone name
managed_zone = "example-zone"
# DNS record
name = "app.example.com."
type = "CNAME"
ttl = 300
rrdatas = ["${module.digital-ocean-nemo.workers_dns}."]
}
```
[^1]: Digital Ocean does offers load balancers. We've opted not to use them to keep the Digital Ocean setup simple and cheap for developers.
## Google Cloud
On Google Cloud, a network load balancer distributes traffic across worker nodes (i.e. a target pool of backends) running an Ingress controller deployment on host ports 80 and 443. Firewall rules allow traffic to ports 80 and 443. Health check rules ensure the target pool only includes worker nodes with a healthy Nginx Ingress controller.
Create the Ingress controller deployment, service, RBAC roles, RBAC bindings, default backend, and namespace.
```
kubectl apply -R -f addons/nginx-ingress/google-cloud
```
For each application, add a DNS record resolving to the network load balancer's IPv4 address.
```
app1.example.com -> 11.22.33.44
aap2.example.com -> 11.22.33.44
app3.example.com -> 11.22.33.44
```
Find the IPv4 address with `gcloud compute addresses list` or use the Typhoon module's output `ingress_static_ip`. For example, you might use Terraform to manage a Google Cloud DNS record:
```tf
resource "google_dns_record_set" "some-application" {
# DNS zone name
managed_zone = "example-zone"
# DNS record
name = "app.example.com."
type = "A"
ttl = 300
rrdatas = ["${module.google-cloud-yavin.ingress_static_ip}"]
}
```
## Bare-Metal
On bare-metal, routing traffic to Ingress controller pods can be done in number of ways.
### Equal-Cost Multi-Path
Deploy the Nginx Ingress Controller as a deployment. Deploy the service with a fixed ClusterIP (e.g. 10.3.0.12) in the Kubernetes service IPv4 CIDR range. There is no need for a NodePort or for pods to bind host ports. Any node can proxy packets destined for the service's ClusterIP to a node which has a pod endpoint.
Configure the network router or load balancer with a static route for the Kubernetes service range and set the next hop to a node. Repeat for each node and set the metric (i.e. cost) of each. Finally, DNAT traffic destined for the WAN on ports 80 or 443 to the service's fixed ClusterIP.
Add a DNS record resolving to the WAN for each application.
```tf
resource "google_dns_record_set" "some-application" {
# Managed DNS Zone name
managed_zone = "dghubble-io"
# Name of the DNS record
name = "app.example.com."
type = "A"
ttl = 300
rrdatas = ["SOME-WAN-IP"]
}
```

# Prometheus
Prometheus collects metrics (e.g. `node_memory_usage_bytes`) from *targets* by scraping their HTTP metrics endpoints. Targets are organized into *jobs*, defined in the Prometheus config. Targets may expose counter, gauge, histogram, or summary metrics.
Here's a simple config from the Prometheus [tutorial](https://prometheus.io/docs/introduction/getting_started/).
```
global:
scrape_interval: 15s
scrape_configs:
- job_name: 'prometheus'
scrape_interval: 5s
static_configs:
- targets: ['localhost:9090']
```
On Kubernetes clusters, Prometheus is run as a Deployment, configured with a ConfigMap, and accessed via a Service or Ingress.
```
kubectl apply -f addons/prometheus -R
```
The ConfigMap configures Prometheus to target apiserver endpoints, node metrics, cAdvisor metrics, and exporters. By default, data is kept in an `emptyDir` so it is persisted until the pod is rescheduled.
### Exporters
Exporters expose metrics for 3rd-party systems that don't natively expose Prometheus metrics.
* [node_exporter](https://github.com/prometheus/node_exporter) - DaemonSet that exposes a machine's hardware and OS metrics
* [kube-state-metrics](https://github.com/kubernetes/kube-state-metrics) - Deployment that exposes Kubernetes object metrics
* [blackbox_exporter](https://github.com/prometheus/blackbox_exporter) - Scrapes HTTP, HTTPS, DNS, TCP, or ICMP endpoints and exposes availability as metrics
### Queries and Alerts
Prometheus provides a simplistic UI for querying metrics and viewing alerts. Use `kubectl` to authenticate to the apiserver and create a local port-forward to the Prometheus pod.
```
kubectl get pods -n monitoring
kubectl port-forward prometheus-POD-ID 9090 -n monitoring
```
Visit [127.0.0.1:9090](http://127.0.0.1:9090) to query [expressions](http://127.0.0.1:9090/graph), view [targets](http://127.0.0.1:9090/targets), or check [alerts](http://127.0.0.1:9090/alerts).
![Prometheus Graph](/img/prometheus-graph.png)
<br/>
![Prometheus Targets](/img/prometheus-targets.png)
<br/>
![Prometheus Alerts](/img/prometheus-alerts.png)
## Grafana
Grafana can be used to build dashboards and rich visualizations that use Prometheus as the datasource. Create the grafana deployment and service.
```
kubectl apply -f addons/grafana -R
```
Use `kubectl` to authenticate to the apiserver and create a local port-forward to the Grafana pod.
```
kubectl port-forward grafana-POD-ID 8080 -n monitoring
```
Visit [127.0.0.1:8080](http://127.0.0.1:8080), add the prometheus data-source (http://prometheus.monitoring.svc.cluster.local), and import your desired dashboard (e.g. 315).

# AWS
In this tutorial, we'll create a Kubernetes v1.8.3 cluster on AWS.
We'll declare a Kubernetes cluster in Terraform using the Typhoon Terraform module. On apply, a VPC, gateway, subnets, auto-scaling groups of controllers and workers, network load balancers for controllers and workers, and security groups will be created.
Controllers and workers are provisioned to run a `kubelet`. A one-time [bootkube](https://github.com/kubernetes-incubator/bootkube) bootstrap schedules an `apiserver`, `scheduler`, `controller-manager`, and `kube-dns` on controllers and runs `kube-proxy` and `calico` or `flannel` on each node. A generated `kubeconfig` provides `kubectl` access to the cluster.
## Requirements
* AWS Account and IAM credentials
* AWS Route53 DNS Zone (registered Domain Name or delegated subdomain)
* Terraform v0.10.4+ and [terraform-provider-ct](https://github.com/coreos/terraform-provider-ct) installed locally
## Terraform Setup
Install [Terraform](https://www.terraform.io/downloads.html) v0.10.1 on your system.
```sh
$ terraform version
Terraform v0.10.7
```
Add the [terraform-provider-ct](https://github.com/coreos/terraform-provider-ct) plugin binary for your system.
```sh
wget https://github.com/coreos/terraform-provider-ct/releases/download/v0.2.0/terraform-provider-ct-v0.2.0-linux-amd64.tar.gz
tar xzf terraform-provider-ct-v0.2.0-linux-amd64.tar.gz
sudo mv terraform-provider-ct-v0.2.0-linux-amd64/terraform-provider-ct /usr/local/bin/
```
Add the plugin to your `~/.terraformrc`.
```
providers {
ct = "/usr/local/bin/terraform-provider-ct"
}
```
Read [concepts](concepts.md) to learn about Terraform, modules, and organizing resources. Change to your infrastructure repository (e.g. `infra`).
```
cd infra/clusters
```
## Provider
Login to your AWS IAM dashboard and find your IAM user. Select "Security Credentials" and create an access key. Save the id and secret to a file that can be referenced in configs.
```
[default]
aws_access_key_id = xxx
aws_secret_access_key = yyy
```
Configure the AWS provider to use your access key credentials in a `providers.tf` file.
```tf
provider "aws" {
region = "eu-central-1"
shared_credentials_file = "/home/user/.config/aws/credentials"
}
```
Additional configuration options are described in the `aws` provider [docs](https://www.terraform.io/docs/providers/aws/).
!!! tip
Regions are listed in [docs](http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region) or with `aws ec2 describe-regions`.
## Cluster
Define a Kubernetes cluster using the module `aws/container-linux/kubernetes`.
```tf
module "aws-tempest" {
source = "git::https://github.com/poseidon/typhoon//aws/container-linux/kubernetes"
cluster_name = "tempest"
# AWS
dns_zone = "aws.example.com"
dns_zone_id = "Z3PAABBCFAKEC0"
controller_count = 1
controller_type = "t2.medium"
worker_count = 2
worker_type = "t2.small"
ssh_authorized_key = "ssh-rsa AAAAB3Nz..."
# bootkube
asset_dir = "/home/user/.secrets/clusters/tempest"
}
```
Reference the [variables docs](#variables) or the [variables.tf](https://github.com/poseidon/typhoon/blob/master/aws/container-linux/kubernetes/variables.tf) source.
## ssh-agent
Initial bootstrapping requires `bootkube.service` be started on one controller node. Terraform uses `ssh-agent` to automate this step. Add your SSH private key to `ssh-agent`.
```sh
ssh-add ~/.ssh/id_rsa
ssh-add -L
```
!!! warning
`terrafrom apply` will hang connecting to a controller if `ssh-agent` does not contain the SSH key.
## Apply
Initialize the config directory if this is the first use with Terraform.
```sh
terraform init
```
Get or update Terraform modules.
```sh
$ terraform get # downloads missing modules
$ terraform get --update # updates all modules
Get: git::https://github.com/poseidon/typhoon (update)
Get: git::https://github.com/poseidon/bootkube-terraform.git?ref=v0.8.2 (update)
```
Plan the resources to be created.
```sh
$ terraform plan
Plan: 98 to add, 0 to change, 0 to destroy.
```
Apply the changes to create the cluster.
```sh
$ terraform apply
...
module.aws-tempest.null_resource.bootkube-start: Still creating... (4m50s elapsed)
module.aws-tempest.null_resource.bootkube-start: Still creating... (5m0s elapsed)
module.aws-tempest.null_resource.bootkube-start: Creation complete after 11m8s (ID: 3961816482286168143)
Apply complete! Resources: 98 added, 0 changed, 0 destroyed.
```
In 4-8 minutes, the Kubernetes cluster will be ready.
## Verify
[Install kubectl](https://coreos.com/kubernetes/docs/latest/configure-kubectl.html) on your system. Use the generated `kubeconfig` credentials to access the Kubernetes cluster and list nodes.
```
$ KUBECONFIG=/home/user/.secrets/clusters/tempest/auth/kubeconfig
$ kubectl get nodes
NAME STATUS AGE VERSION

```
## Going Further
Learn about [version pinning](concepts.md#versioning), maintenance, and [addons](addons/overview.md).
!!! note
On Container Linux clusters, install the `container-linux-update-operator` addon to coordinate reboots and drains when nodes auto-update. Otherwise, updates may not be applied until the next reboot.
## Variables
### Required
| Name | Description | Example |
|:-----|:------------|:--------|
| cluster_name | Unique cluster name (prepended to dns_zone) | "tempest" |
| dns_zone | AWS Route53 DNS zone | "aws.example.com" |
| dns_zone_id | AWS Route53 DNS zone id | "Z3PAABBCFAKEC0" |
| ssh_authorized_key | SSH public key for ~/.ssh_authorized_keys | "ssh-rsa AAAAB3NZ..." |
| os_channel | Container Linux AMI channel | stable, beta, alpha |
| asset_dir | Path to a directory where generated assets should be placed (contains secrets) | "/home/user/.secrets/clusters/tempest" |
#### DNS Zone
Clusters create a DNS A record `${cluster_name}.${dns_zone}` to resolve a network load balancer backed by controller instances. This FQDN is used by workers and `kubectl` to access the apiserver. In this example, the cluster's apiserver would be accessible at `tempest.aws.example.com`.
You'll need a registered domain name or subdomain registered in a AWS Route53 DNS zone. You can set this up once and create many clusters with unqiue names.
```tf
resource "aws_route53_zone" "zone-for-clusters" {
name = "aws.example.com."
}
```
Reference the DNS zone id with `"${aws_route53_zone.zone-for-clusters.zone_id}"`.
!!! tip ""
If you have an existing domain name with a zone file elsewhere, just carve out a subdomain that can be managed on Route53 (e.g. aws.mydomain.com) and [update nameservers](http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/SOA-NSrecords.html).
### Optional
| Name | Description | Default | Example |
|:-----|:------------|:--------|:--------|
| controller_count | Number of controllers (i.e. masters) | 1 | 1 |
| controller_type | Controller EC2 instance type | "t2.small" | "t2.medium" |
| worker_count | Number of workers | 1 | 3 |
| worker_type | Worker EC2 instance type | "t2.small" | "t2.medium" |
| disk_size | Size of the EBS volume in GB | "40" | "100" |
| networking | Choice of networking provider | "calico" | "calico" or "flannel" |
| network_mtu | CNI interface MTU (calico only) | 1480 | 8981 |
| host_cidr | CIDR range to assign to EC2 instances | "10.0.0.0/16" | "10.1.0.0/16" |
| pod_cidr | CIDR range to assign to Kubernetes pods | "10.2.0.0/16" | "10.22.0.0/16" |
| service_cidr | CIDR range to assgin to Kubernetes services | "10.3.0.0/16" | "10.3.0.0/24" |
Check the list of valid [instance types](https://aws.amazon.com/ec2/instance-types/).
!!! tip "MTU"
If your EC2 instance type supports [Jumbo frames](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/network_mtu.html#jumbo_frame_instances) (most do), we recommend you change the `network_mtu` to 8991! You will get better pod-to-pod bandwidth.
