From f2f4deb8bb44988eeb0b64b919e51fb556aef4fb Mon Sep 17 00:00:00 2001 From: Dalton Hubble Date: Tue, 18 Dec 2018 12:29:27 -0800 Subject: [PATCH] Change AWS default type from t2.small to t3.small * T3 is the next generation general purpose burstable instance type. Compared with t2.small, the t3.small is cheaper, has 2 vCPU (instead of 1) and provides 5 Gbps of pod-to-pod bandwidth (instead of 1 Gbps) --- CHANGES.md | 5 +++++ aws/container-linux/kubernetes/variables.tf | 4 ++-- aws/fedora-atomic/kubernetes/variables.tf | 4 ++-- docs/atomic/aws.md | 4 ++-- docs/cl/aws.md | 4 ++-- docs/topics/performance.md | 14 +++++++------- 6 files changed, 20 insertions(+), 15 deletions(-) diff --git a/CHANGES.md b/CHANGES.md index 5bb8f70a..dfa7ca8a 100644 --- a/CHANGES.md +++ b/CHANGES.md @@ -4,6 +4,11 @@ Notable changes between versions. ## Latest +#### AWS + +* Change `controller_type` and `worker_type` default from t2.small to t3.small + * t3.small is cheaper, provides 2 vCPU (instead of 1), and 5 Gbps of pod-to-pod bandwidth! + ## v1.13.1 * Kubernetes [v1.13.1](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.13.md#v1131) diff --git a/aws/container-linux/kubernetes/variables.tf b/aws/container-linux/kubernetes/variables.tf index 8ccfdd43..c1912c99 100644 --- a/aws/container-linux/kubernetes/variables.tf +++ b/aws/container-linux/kubernetes/variables.tf @@ -31,13 +31,13 @@ variable "worker_count" { variable "controller_type" { type = "string" - default = "t2.small" + default = "t3.small" description = "EC2 instance type for controllers" } variable "worker_type" { type = "string" - default = "t2.small" + default = "t3.small" description = "EC2 instance type for workers" } diff --git a/aws/fedora-atomic/kubernetes/variables.tf b/aws/fedora-atomic/kubernetes/variables.tf index 995bee79..538923f6 100644 --- a/aws/fedora-atomic/kubernetes/variables.tf +++ b/aws/fedora-atomic/kubernetes/variables.tf @@ -31,13 +31,13 @@ variable "worker_count" { variable "controller_type" { type = "string" - default = "t2.small" + default = "t3.small" description = "EC2 instance type for controllers" } variable "worker_type" { type = "string" - default = "t2.small" + default = "t3.small" description = "EC2 instance type for workers" } diff --git a/docs/atomic/aws.md b/docs/atomic/aws.md index 5abc3b02..73950dfa 100644 --- a/docs/atomic/aws.md +++ b/docs/atomic/aws.md @@ -224,8 +224,8 @@ Reference the DNS zone id with `"${aws_route53_zone.zone-for-clusters.zone_id}"` |:-----|:------------|:--------|:--------| | controller_count | Number of controllers (i.e. masters) | 1 | 1 | | worker_count | Number of workers | 1 | 3 | -| controller_type | EC2 instance type for controllers | "t2.small" | See below | -| worker_type | EC2 instance type for workers | "t2.small" | See below | +| controller_type | EC2 instance type for controllers | "t3.small" | See below | +| worker_type | EC2 instance type for workers | "t3.small" | See below | | disk_size | Size of the EBS volume in GB | "40" | "100" | | disk_type | Type of the EBS volume | "gp2" | standard, gp2, io1 | | disk_iops | IOPS of the EBS volume | "0" (i.e. auto) | "400" | diff --git a/docs/cl/aws.md b/docs/cl/aws.md index b0cfc92e..5a805073 100644 --- a/docs/cl/aws.md +++ b/docs/cl/aws.md @@ -236,8 +236,8 @@ Reference the DNS zone id with `"${aws_route53_zone.zone-for-clusters.zone_id}"` |:-----|:------------|:--------|:--------| | controller_count | Number of controllers (i.e. masters) | 1 | 1 | | worker_count | Number of workers | 1 | 3 | -| controller_type | EC2 instance type for controllers | "t2.small" | See below | -| worker_type | EC2 instance type for workers | "t2.small" | See below | +| controller_type | EC2 instance type for controllers | "t3.small" | See below | +| worker_type | EC2 instance type for workers | "t3.small" | See below | | os_image | AMI channel for a Container Linux derivative | coreos-stable | coreos-stable, coreos-beta, coreos-alpha, flatcar-stable, flatcar-beta, flatcar-alpha | | disk_size | Size of the EBS volume in GB | "40" | "100" | | disk_type | Type of the EBS volume | "gp2" | standard, gp2, io1 | diff --git a/docs/topics/performance.md b/docs/topics/performance.md index d6acf7bf..5b0d16f3 100644 --- a/docs/topics/performance.md +++ b/docs/topics/performance.md @@ -6,7 +6,7 @@ Provisioning times vary based on the operating system and platform.
