SSH 到 Azure 上的 DCOS 主機要求輸入密碼
我剛剛在 Azure 上設置了一個 DC/OS 集群。我基本上只是按照安裝指南中的說明進行操作。到目前為止一切順利，一切都按預期工作。
用於安裝 DC/OS 的 Terraform 配置：
variable "dcos_install_mode" { description = "specifies which type of command to execute. Options: install or upgrade" default = "install" } data "http" "whatismyip" { url = "http://whatismyip.akamai.com/" } provider "azurerm" { version = "~> 1.16.0" } module "dcos" { source = "dcos-terraform/dcos/azurerm" version = "~> 0.1.0" dcos_instance_os = "coreos_1855.5.0" cluster_name = "dcos-sandbox" ssh_public_key_file = "~/.ssh/dcos-sandbox@azure.pub" admin_ips = ["${data.http.whatismyip.body}/32"] location = "West Europe" num_masters = "1" num_private_agents = "3" num_public_agents = "0" masters_vm_size = "Standard_D2s_v3" private_agents_vm_size = "Standard_B2s" public_agents_vm_size = "Standard_B2s" dcos_version = "1.12.0" # dcos_variant = "ee" # dcos_license_key_contents = "${file("./license.txt")}" dcos_variant = "open" providers = { azurerm = "azurerm" } dcos_install_mode = "${var.dcos_install_mode}" } output "masters-ips" { value = "${module.dcos.masters-ips}" } output "cluster-address" { value = "${module.dcos.masters-loadbalancer}" } output "public-agents-loadbalancer" { value = "${module.dcos.public-agents-loadbalancer}" }現在我需要通過 SSH 連接到主節點。根據文件，我應該能夠執行
dcos node ssh --master-proxy --leader但由於某種原因，主節點不接受我的公鑰，而是要求輸入密碼。

SSH 客戶端提供了我在使用 terraform 安裝 DC/OS 時使用的 SSH 密鑰。
任何想法我做錯了什麼？
對於任何有同樣問題的人，文件在這一點上似乎還不清楚。文件暗示使用 coreOS 時預設使用者是“核心”。這是錯誤的。Terraform 將管理員使用者設置為“dcos_admin”。
我終於能夠通過 ssh 進入主節點
dcos node ssh --master-proxy --leader --user=dcos_admin
