Dalton Hubble 2265ab5375 Remove Kubelet `--network-plugin=cni` flag 
* Now that `docker-shim` is no longer used, the Kubelet flag
is no longer needed and will be removed in v1.24
 2022-01-14 10:43:07 -08:00
Dalton Hubble 08ea9776f3 Mask docker.service to prevent socket activation 
* Kubelet now uses `containerd` as the container runtime, but
`docker.service` still starts when `docker.sock` is probed bc
the service is socket activated. Prevent this by masking the
`docker.service` unit

 2022-01-14 10:25:45 -08:00
Dalton Hubble beb9f1477a Add experimental Flatcar Linux arm64 support on AWS 
* Add `arch` variable to Flatcar Linux AWS `kubernetes` and
`workers` modules. Accept `amd64` (default) or `arm64` to support
native arm64/aarch64 clusters or mixed/hybrid clusters with arm64
workers
* Requires `flannel` or `cilium` CNI

Dalton Hubble f544a9c71f Switch Fedora CoreOS from docker-shim to containerd 
* Migrate from `docker-shim` to `containerd` in preparation
for Kubernetes v1.24.0 dropping `docker-shim` support
* Much consideration was given to the container runtime
choice. https://github.com/poseidon/typhoon/issues/899

Dalton Hubble 50215e373b Add Prometheus config for monitoring Kubernetes Ingress 
* Allow Kubernetes Ingress resources to be probed via Blackbox
Exporter (if present) if annotated `prometheus.io/probe: "true"`
* Fix probes of Services via Blackbox Exporter. Require Blackbox
Exporter to be deployed in the same `monitoring` namespace, be
named `blackbox-exporter`, and use port 8080
 2021-12-29 11:57:50 -08:00
Dalton Hubble a9f9c59b91 Configure Prometheus to allow a custom scrape query param 
* Set `prometheus.io/param` on a Kubernetes Service to scrape
the service endpoints and pass a custom query parameter
* For example, scrape Consul with `?format=prometheus`

```yaml
kind: Service
metadata:
  annotations:
    prometheus.io/scrape: 'true'
    prometheus.io/port: '8500'
    prometheus.io/path: /v1/agent/metrics
    prometheus.io/param: format=prometheus

Dalton Hubble 6ed048eb65 Workaround Terraform v1.1 file provisioner regression 
* Terraform v1.1 changed the behavior of provisioners and
`remote-exec` in a way that breaks support for expansions
in commands (including file provisioner, where `destination`
is part of an `scp` command)
* Terraform will likely revert the change eventually, but I
suspect it will take a while
* Instead, we can stop relying on Terraform's expansion
behavior. `/home/core` is a suitable choice for `$HOME` on
both Flatcar Linux and Fedora CoreOS (harldink `/var/home/core`)

Dalton Hubble 136107b448 Set Kubelet resolver config to /run/systemd/resolve/resolv.conf 
* Both Flatcar Linux and Fedora CoreOS use systemd-resolved,
but they setup /etc/resolv.conf symlinks differently
* Prefer using /run/systemd/resolve/resolv.conf directly, which
also updates to reflect runtime changes (e.g. resolvectl)

Dalton Hubble e97c1cc9e5 Enable Kubernetes aggregation by default 
* Change `enable_aggregation` default from false to true
* These days, Kubernetes control plane components emit annoying
messages related to assumptions baked into the Kubernetes API
Aggregation Layer if you don't enable it. Further the conformance
tests force you to remember to enable it if you care about passing
those
* This change is motivated by eliminating annoyances, rather than
any enthusiasm for Kubernetes' aggregation features

Dalton Hubble 9c626c9dbd Change default `disk_iops` from unset to 3000 
* Since v1.21.3 switched controllers default disk type from
`gp2` to `gp3`, an iops diff has been shown (harmless, but
annoying)
* Controller nodes default to a 30GB `gp3` disk. `gp3` disks
do respect `iops` and the corresponding default is 3000

Dalton Hubble 85252dec6e Switch FCOS workers to official Fedora CoreOS AMIs 
* Fix worker nodes to use official Fedora CoreOS AMIs,
instead of the older Poseidon built AMIs (now removed).
This should have been part of #1038, but was missed in
code review
* Poseidon build AMIs have been deleted (so I don't have
to keep paying to host them for people)
