Question

我正在尝试将Vault作为Kubernetes上的StatefulSet运行。

我有一个基于此的工作领事群集： https://github.com/kelseyhightower/consul-on-kubernetes

我的Vault的sts文件如下所示：

kind: StatefulSet
metadata:
  name: vault
spec:
  serviceName: vault
  replicas: 2
  template:
    metadata:
      labels:
        app: vault
    spec:
      affinity:
        podAntiAffinity:
          requiredDuringSchedulingIgnoredDuringExecution:
            - labelSelector:
                matchExpressions:
                  - key: app
                    operator: In
                    values:
                      - vault
              topologyKey: kubernetes.io/hostname
      containers:
        - name: vault
          image: "vault:0.9.0"
          ports:
          - containerPort: 8200
            name: http
          - containerPort: 8201
            name: backend
          args:
            - "server -config=/vault/config/vault-server.json"
          securityContext:
            capabilities:
              add:
                - IPC_LOCK
          volumeMounts:
            - name: config
              mountPath: /vault/config
            - name: tls
              mountPath: /etc/tls
      volumes:
        - name: config
          configMap:
            name: vault
        - name: tls
          secret:
            secretName: vault

我的配置文件看起来像这样

{
    "disable_mlock": true,
    "listener": [
        {
            "tcp": {
                "tls_disable": true
            }
        }
    ],
    "storage": {
        "consul": {
            "address": "consul.default.svc.cluster.local:8500",
            "path": "vault",
            "token": "7e21f292-e7e7-f879-210c-4af2ae483cac"
        }
    }
}

当我应用StatefulSet时，我收到绑定错误

Error initializing listener of type tcp: listen tcp 127.0.0.1:8200: bind: address already in use

我尝试使用不同的端口添加127.0.0.1和0.0.0.0的侦听器。 pod正在读取配置文件，因为在我禁用之前我收到了TLS警告。

关于pod上绑定到localhost的内容的任何想法？任何疑难解答帮助将不胜感激

问题是Docker容器以开发模式启动库

来自https://github.com/hashicorp/docker-vault/blob/master/0.X/Dockerfile#L69

# By default you'll get a single-node development server that stores everything
# in RAM and bootstraps itself. Don't use this configuration for production.
CMD ["server", "-dev"]

我将statefulSet yaml中的cmd和参数行添加/更改为

command: ["vault", "server"]
args:
  - "-config=/vault/config/vault-server.json"

这摆脱了开发模式并使用服务器模式。

请注意，这不是一个生产就绪的例子，它仅用于学习

您可以尝试一下
替换为：
args: - "server -config=/vault/config/vault-server.json"

将此添加到您的yaml文件中
command: ["vault", "server", "-config", "/vault/config/config.json"]
