小编Sno*_*ash的帖子

鉴于这种:

resource "aws_instance" "example" {
  ami           = "ami-2757f631"
  instance_type = "t2.micro"
}

resource "aws_eip" "ip" {
  instance = "${aws_instance.example.id}"
}

来自https://www.terraform.io/intro/getting-started/dependencies.html

我收到一个错误:

* aws_eip.ip: Failure associating EIP: InvalidParameterCombination: You must specify an allocation id when mapping an address to a VPC instance

知道为什么吗？

为什么要执行此任务（来自使用 ansible 启动 aws ec2 实例的最佳方法）：

  - name: Add the newly created EC2 instance(s) to the local host group (located inside the directory)
    local_action: lineinfile 
                  dest="./hosts" 
                  regexp={{ item.public_ip }} 
                  insertafter="[webserver]" line={{ item.public_ip }}
    with_items: ec2.instances

创建这个错误？

Lambda有100个功能限制.

当100已经运行时提交101功能会发生什么？

它会:

• 失败并出错
• 排队

我有一段非常简单的Terraform代码：

provider "aws" {
  region = "eu-west-1"
}

module ec2 {
  source = "./ec2_instance"
  name = "EC2 Instance 1"
} 

模块在哪里：

variable "name" {
    default = "Default Name from ec2_instance.tf"
}

resource "aws_instance" "example" {
  ami = "ami-e5083683"
  instance_type = "t2.nano"
  subnet_id = "subnet-3e976259"
  associate_public_ip_address = true
  security_groups = [ "sg-7310e10b" ]
  tags {
    Name = "${var.name}"
  }
}

当我第一次运行它时，我得到以下输出：

security_groups.#:            "" => "1"
security_groups.1642973399:   "" => "sg-7310e10b"

但是，下一次我尝试plan得到：

  security_groups.#:            "0" => "1" (forces new resource)
  security_groups.1642973399:   "" …

我有 2 个虚拟机。

我第一次运行时：

docker swarm join-token manager

第二次我运行此命令的结果。

IE

docker swarm join --token SWMTKN-1-0wyjx6pp0go18oz9c62cda7d3v5fvrwwb444o33x56kxhzjda8-9uxcepj9pbhggtecds324a06u 192.168.65.3:2377

然而，这输出：

Error response from daemon: rpc error: code = Unavailable desc = all SubConns are in TransientFailure, latest connection error: connection error: desc = "transport: Error while dialing dial tcp 192.168.65.3:2377: connect: connection refused"

知道出了什么问题吗？

如果有帮助的话，我会使用 Vagrant 来启动这些虚拟机。

pod.yml

apiVersion: v1
kind: Pod
metadata:
    name: hello-pod
    labels:
        zone: prod
        version: v1
spec:
    containers:
    - name: hello-ctr
      image: hello-world:latest
      ports:
      - containerPort: 8080

kubectl create -f pod.yml

kubectl get pods
NAME        READY     STATUS             RESTARTS   AGE
hello-pod   0/1       CrashLoopBackOff   5          5m

为什么CrashLoopBackOff？

根据文档：

https://kubernetes.io/docs/reference/ generated/kubectl/kubectl-commands#run

kubectl run NAME --image=image

将运行图像。

一些问题：

• 我认为这是一个 Pod，而不是一个容器？

• 我假设 NAME 与 pod 相关联？

我不是在谈论 GUI 或网络应用程序。

我说的是 REPL。例如，在 Python 中，我会简单地运行python以获取 REPL。

groovy 只是输出一些帮助文本。

Kubernetes 仪表板输出一堆错误消息。

你应该忽略他们吗？如果没有，你如何解决它们？

我已将Box2D添加到我正在研究的Cocos2D项目中.

我已经按照几个指南来说明如何做到这一点(所有这些似乎都不同!).但是,似乎都没有效果.

我遇到了这些类型的错误:

错误:Box2D/Collision/b2BroadPhase.h:没有这样的文件或目录

我以为我的标题搜索路径错了,但尝试了各种各样的变种而没有运气.

有什么建议？
