On clusters running in 10.0.0.0/8 --cluster-dns is incorrectly configured

At some point AWS made a change to change the IP address of the Cluster DNS service to 172.20.0.10 for clusters running anywhere in the 10.0.0.0/8 range

Example Packer Configs ...

There should be some example packer configs to build working AMIs

Not sure if they belong in this repo or somewhere else?

Fail early with an appropriate error message if not on AWS EC2

Currently, running ekstrap outside of AWS EC2 returns the following error message:

2018/06/25 19:29:45 InvalidEndpointURL: invalid endpoint uri

    <body></body>
.amazonaws.com/: invalid character " " in host name

It probably should check if it is running on EC2 and fail with an error message in the vein of "Running outside of EC2, cannot configure node.'

Release tooling

We need some tooling to build the binary etc

Build and attach binary to Github release
Checksums

Optional:

OS Packages
Containerised version
Signed binary

Test Systemd Code

Make systemd enable the service if it is not allready

Make Repo Public

Adds unit file to OS packages

We should add a systemd unit file somewhat similar to the example one here https://github.com/errm/ekstrap/blob/master/example/ekstrap.service to the OS packages ...

Cert error on EKS with k8s version 1.11.5

Error when running kubectl exec / kubectl logs / kubectl port-forward

Error from server: Get https://10.20.73.201:10250/containerLogs/kube-system/traefik-ingress-controller-6f6d87769d-w8tq5/traefik-ingress-lb: x509: cannot validate certificate for 10.20.73.201 because it doesn't contain any IP SANs

Support other init systems

Currently we only support systemd... we could support other init systems ... but does anyone even use them?

Add some logic to correctly set --max-pods

See: https://kubernetes.slack.com/archives/C8SH2GSL9/p1529842068000024

Only restart if needed ...

Only trigger a kubelet restart if its needed ...

Support ARM

This is a thing... https://github.com/aws/containers-roadmap/tree/master/preview-programs/eks-ec2-a1-preview

EKS should work with it!

Set hostname

Some aws cloudprovider stuff in kubernetes expects the hostname to == PrivateDNSName

we should replicate the ruby/bin/k8s-set-hostname...

If the instance doesn't have the tag yet wait for it ...

When EC2 instances are launched from an ASG the tags are not applied straight away ... if we can't find them we should loop and & poll.

README

Project needs a readme ...

It should explain what this does and why ...

Setup CI

Travis?

Github Actions

Switch from travis to Github Actions for CI and Release!

Push OS packages to a package repo

Installation instructions will be a lot simpler with a proper package repo ...

https://bintray.com or somesuch ...

Reimpliment Code Generation in go

#58 introduces some code generation as a ruby script that pulls some data from AWS pricing API and documentation. It would be nice to reimplement this using go tools.

Looks like these are some good candidates:

https://github.com/gocolly/colly - scraping framework
https://github.com/dave/jennifer - code generation

If we are in ClusterStatusActive we can continue as normal

If there is ClusterStatusDeleting or ClusterStatusFailed we should fail fast ...
