更換default AMI 使用Kops Debian官方AMI #96

Closed pahud closed 5 years ago

pahud commented 5 years ago

根據這個thread， 目前default CoreOS AMI存在穩定性問題，包括Amazon Linux 2 AMI也有尚未解決的問題，我準備把default AMI改成Kops官方Deiban AMI, 目前在cn-north-1 and cn-northwest-1有看到這些Community AMI，但不確定是否為 kope.io 官方身分上傳 (參考這裡官方說明)

此外，根據這裡定義，目前建議版本應該是kope.io/k8s-1.12-debian-stretch-amd64-hvm-ebs-2019-05-13, 但這個image目前在北京寧夏Region都還找不到。

下面這兩個AMI可以被找到，但不確定是不是KOPS官方AMI，有可能是其他用戶自己打包上傳的，可能存在一些疑慮。

cn-north-1 ami-076828ef599fb3764 image

cn-northwest-1 ami-0b46e70fdcdae1aef image

正在根據這篇文件說明，將海外 kope.io/k8s-1.12-debian-stretch-amd64-hvm-ebs-2019-05-13 這個kops default platform image搬到CN來試試看。

我们最近新建集群的时候也遇到了这种情况，准备用你发的新AMI试试，不过我有个疑问，因为我们的新集群已经创建了，我要更改AMI是不是必须得把现在的集群删除重新创建呢还是可以edit然后update。

剛剛更新了Debian AMI

已修改Makefile，現在開始改用Debian AMI

ifeq ($(TARGET_REGION) ,cn-north-1)
    CLUSTER_NAME ?= cluster.bjs.k8s.local
    # copy from kope.io/k8s-1.12-debian-stretch-amd64-hvm-ebs-2019-05-13
    # see https://github.com/nwcdlabs/kops-cn/issues/96
    AMI ?= ami-02dd4d384eb0e0b3a
    ZONES ?= cn-north-1a,cn-north-1b
endif

ifeq ($(TARGET_REGION) ,cn-northwest-1)
    CLUSTER_NAME ?= cluster.zhy.k8s.local
    # copy from kope.io/k8s-1.12-debian-stretch-amd64-hvm-ebs-2019-05-13
    # see https://github.com/nwcdlabs/kops-cn/issues/96
    AMI ?= ami-068b32c3754324d44
    ZONES ?= cn-northwest-1a,cn-northwest-1b,cn-northwest-1c
endif

實際測試，搭配最新kops-1.12.3沒問題
