kubernetes - 无法使用Kops命令创建集群

Question

使用kops命令创建k8集群时遇到问题。

这是我尝试创建集群时遇到的错误。

W1104 16:31:41.803150   18534 apply_cluster.go:945] **unable to pre-create DNS records - cluster startup may be slower: Error pre-creating DNS records: InvalidChangeBatch**: [RRSet with DNS name api.dev.devops.com. is not permitted in zone uswest2.dev.devops.com., RRSet with DNS name api.internal.dev.devops.com. is not permitted in zone uswest2.dev.devops.com.]

我用来创建集群的命令:

kops create cluster --cloud=aws --zones=us-west-2b --name=dev.devops.com --dns-zone=uswest2.dev.devops.com --dns private

kops update cluster --name dev.devops.com --yes

有人可以帮帮我吗。提前致谢!!

Answer 1

您已经将dns-zone注册为uswest2.dev.devops.com，并且在命令中引用的名称是dev.devops.com。

如果您检查this docs，尤其是Configure DNS部分，您会发现:

In this scenario you want to contain all kubernetes records under a subdomain of a domain you host in Route53. This requires creating a second hosted zone in route53, and then setting up route delegation to the new zone.

In this example you own example.com and your records for Kubernetes would look like etcd-us-east-1c.internal.clustername.subdomain.example.com

您将根据以下doc示例找到该文件:etcd-us-east-1c.internal.clustername.subdomain.example.com您的dev.devops.com是域，而uswest2.dev.devops.com是您的子域。

在Route 53文档中，您将找到示例，在这种情况下，example.org的子域被设置为kopsclustertest

export ID=$(uuidgen)
echo $ID
ae852c68-78b3-41af-85ee-997fc470fd1c

aws route53 \
create-hosted-zone \
--output=json \
--name kopsclustertest.example.org \
--caller-reference $ID | \
jq .DelegationSet.NameServers

[
  "ns-1383.awsdns-44.org",
  "ns-829.awsdns-39.net",
  "ns-346.awsdns-43.com",
  "ns-1973.awsdns-54.co.uk"
]

此时:
子域: kopsclustertest 域: example.org
在下面的几章中，您将找到 KOPS集群创建部分。

kops create cluster \
--cloud=aws \
--master-zones=us-east-1a,us-east-1b,us-east-1c \
--zones=us-east-1a,us-east-1b,us-east-1c \
--node-count=2 \
--node-size=t2.micro \
--master-size=t2.micro \
${NAME}

带有信息

The environment variable ${NAME} was previously exported with our cluster name: mycluster01.kopsclustertest.example.org.

这意味着在subdomain.domain之前，您需要指定集群名称。

简而言之，在标记--name中，您必须指定:<your_cluster_name>.subdomain.domain
请尝试:
kops create cluster --cloud=aws --zones=us-west-2b --name=my-cluster.uswest2.dev.devops.com --dns-zone=uswest2.dev.devops.com --dns private
