## Amazon EKS (notes)
|

|

- Convenient if you *have to* use AWS
|
||||
|

- Needs extra steps to be truly production-ready
|

|
||||
- [Versions tend to be outdated](https://twitter.com/jpetazzo/status/1252948707680686081)
|
||||
|
||||
- The only officially supported pod network is the [Amazon VPC CNI plugin](https://docs.aws.amazon.com/eks/latest/userguide/pod-networking.html)
|
||||
|
||||
- integrates tightly with security groups and VPC networking
|
||||
|
||||
- not suitable for high density clusters (with many small pods on big nodes)
|
||||
|
||||
- other plugins [should still work](https://docs.aws.amazon.com/eks/latest/userguide/alternate-cni-plugins.html) but will require extra work

- Well-rounded product overall
|

|

(it used to be one of the best managed Kubernetes offerings available;

now that many other providers entered the game, that title is debatable)

- The cluster comes with many add-ons

- Versions lag a bit:

- latest minor version (e.g. 1.18) tends to be unsupported

- previous minor version (e.g. 1.17) supported through alpha channel

## Scaleway (initial setup)
|
||||
|
||||
- After creating your account, make sure you set a password or get an API key
|
||||
|
||||
(by default, it uses email "magic links" to sign in)
|
||||
|
||||
- Install `scw`
|
||||
|
||||
(you need [CLI v2](https://github.com/scaleway/scaleway-cli/tree/v2#Installation), which in beta as of May 2020)
|
||||
|
||||
- Generate the CLI configuration with `scw init`
|
||||
|
||||
(it will prompt for your API key, or email + password)

|

## Scaleway (create cluster)
|
||||
|
||||
- Create the cluster:
|
||||
```bash
|
||||
k8s cluster create name=my-kapsule-cluster version=1.18.3 cni=cilium \
|
||||
default-pool-config.node-type=DEV1-M default-pool-config.size=3
|
||||
```
|
||||
|
||||
- Get cluster ID:
|
||||
```bash
|
||||
scw k8s cluster list
|
||||
# or
|
||||
CLUSTERID=$(scw k8s cluster list -o json | \
|
||||
jq -r '.[] | select(.name="my-kapsule-cluster") | .id')
|
||||
```
|
||||
|
||||
- Check cluster status with e.g. `scw k8s cluster list` on a wide terminal
|
||||
|
||||
- After less than 5 minutes, status should be `ready`
|
||||
|
||||
- Add connection information to your `.kube/config` file:
|
||||
```bash
|
||||
scw k8s kubeconfig install $CLUSTERID
|
||||
```

||||

## Scaleway (cleanup)
|
||||
|
||||

|
||||

||||
- Delete the cluster:
|
||||
```bash
|
||||
scw cluster delete cluster-id=$CLUSTERID
|
||||
```
|
||||
|
||||

|
||||
## Scaleway (notes)
|
||||
|
||||
- The `create` command is a bit more complex than with other providers
|
||||
|
||||
(you must specify the Kubernetes version, CNI plugin, and node type)
|
||||
|
||||
- To see available versions and CNI plugins, run `scw k8s version list`
|
||||
|
||||
- As of May 2020, Kapsule supports:
|
||||
|
||||
- multiple CNI plugins, including: cilium, calico, weave, flannel
|
||||
|
||||
- Kubernetes versions 1.15 to 1.18
|
||||
|
||||
- multiple container runtimes, including: Docker, containerd, CRI-O
|
||||
|
||||
- To see available node types and their price, check their [pricing page](
