为了了解每个文件的所有者EC2 instance，我cloudtrail logs通过 查询存储在 S3 中的文件Athena。

我在 Athena 有一张表，其结构如下：

CREATE EXTERNAL TABLE cloudtrail_logs (
eventversion STRING,
useridentity STRUCT<
               type:STRING,
               principalid:STRING,
               arn:STRING,
               accountid:STRING,
               invokedby:STRING,

我们如何制作 terraform 创建的 launch_template 资源，将标签添加到创建的 EBS 卷并将其附加到使用的 AMI ？

我正在创建一些资源，例如 Alb、安全组，并且我使用 github 中的模块：

module "efs_sg" { 
  source  = "git::https://github.com/terraform-aws-modules/terraform-aws-security-group.git" 
  version = "3.2.0" 

  name        = "${var.default_tags["app"]}-efs" 
  description = "Security group for FE " 
  vpc_id      = data.terraform_remote_state.network.outputs.vpc_id


  computed_ingress_with_source_security_group_id = [ 
    { 
      from_port   = 2049 
      to_port     = 2049 
      protocol    = "tcp" 
      description = "NFS" 
      source_security_group_id = "${module.asg_sg.this_security_group_id}" 
    } 
  ] 
  number_of_computed_ingress_with_source_security_group_id = 1 

  tags      = "${var.default_tags}" 
}

当我执行 terraform apply/plan 时，出现此错误：

错误：版本约束无效

Cannot apply a version constraint to module "efs_sg" (at
terraform/dev/eu-west-1/sg.tf:107) because it has a non Registry
URL. 

我在用着Terraform v0.12.12

如何解决这个问题？

My instance is on this AMI: amzn2-ami-hvm-2.0.20191116.0-x86_64-gp2 (ami-01f14919ba412de34) I want to install docker following this document so here is the output of my commands:

我创建了一个 AWS cloudformation，它创建了一个启动配置和一个自动缩放组。在启动配置中的用户数据中，我配置了文件系统挂载目标，并安装了 cloudwatch 代理：

代码编辑

  "LaunchConfig":{
    "Type":"AWS::AutoScaling::LaunchConfiguration",
    "Metadata" : {
      "AWS::CloudFormation::Init" : {
        "config" : {
          "files" : {
            "/etc/cwlogs.cfg": {
              "content": { "Fn::Join" : ["", [
                "[general]",
                "state_file = /var/awslogs/state/agent-state",
                "[/var/log/syslog]",
                "file = /tmp/",
                "log_group_name = ecs-dataloader",
                "log_stream_name = ECS-loader",
                "datetime_format = %b %d %H:%M:%S"
                ]]},
                "mode": "000755",
                "owner": "root",
                "group": "root"
            },
            "/etc/ecs/ecs.config": {
              "content": { "Fn::Join" : ["", [
                "ECS_CLUSTER=", { "Ref" : "ClusterName" }
              ]]},
              "mode": "000755",
              "owner": "root",
              "group": "root"
            }

我构建了一个 AWS Batch 计算环境。我想在作业中运行一个 python 脚本。这是我正在使用的 docker 文件：

FROM python:slim
RUN apt-get update
RUN pip install boto3 matplotlib awscli
COPY runscript.py /
ENTRYPOINT ["/bin/bash"]

我的任务定义中的命令是：

python /runscript.py

当我在 AWS 控制台中提交作业时，我在 CloudWatch 中收到此错误：

/usr/local/bin/python: /usr/local/bin/python: cannot execute binary file

并且该作业的状态为 FAILED。

出了什么问题？我在本地运行容器，并且可以毫无错误地启动脚本。

如何在Spring MVC 3的控制器中将多个对象添加到ModelAndView中？那可能吗？

我有一个页面jsp,我将使用不同POJO类的许多属性,所以我需要在表单中使用两个commandName.可以在控制器中使用多个@ModelAttribute,那么如果多个commandName不工作又有什么意义呢？

例如,我想插入一个信息,名称和函数,name是类Agent中的一个属性,function是类Activity中的一个属性？我该怎么办？

控制器

@RequestMapping(value="/fiche_service",method=RequestMethod.GET)
    public ModelAndView Fiche_service(@ModelAttribute Activite activitey,@ModelAttribute Etablissement etabl,ModelMap model) {
        Agent ag = new Agent();
        return new ModelAndView("FicheService","agent",ag);

    }

表格

<form:form
    action="${pageContext.request.contextPath}/ajouter_activite"
    method="post" commandName="activity" commandName="etabl">

  <table id="tabmenu">
     <tr>
         <td>Fonction :</td>
         <td><form:input type="text" class="round default-width-input" path="fonction"/></td>
     </tr>
     <tr>
         <td>Nom d'établissement :</td>
         <td><form:input type="text" class="round default-width-input" path="noml"/></td>
     </tr>
     <tr>
         <td>Ville :</td>
         <td><form:input type="text" class="round default-width-input" path="villel"/></td>
     </tr>
     <tr>
         <td>Délégation :</td>
         <td><form:input type="text" class="round default-width-input" path="cd_reg"</td>
     </tr>
     <tr>
         <td>Date début :</td>
         <td><form:input type="text" name="date" class="tcal" value="" path="dateAffect"/></td>
     </tr>
     <tr>
         <td>Date …

在我的应用程序中,我有主表单和子表单.我想ShowIntaskBar为子窗体设置为false,但问题是当我通过菜单打开它时,它会显示并消失,然后当我再次打开它时,它会变得可见.所以我不想打开它两次才能看到它.如何解决这个问题？

子表单代码:

 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load


        Me.ShowInTaskbar = False


    End Sub

父(主)表单代码:

 Private Sub ?????????????ToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ?????????????ToolStripMenuItem.Click
        Form1.ShowDialog()


    End Sub

我可以使用以下代码获取表单的值：

<input type="text" formControlName="subscriptionFormName" id="subscriptionFormName" #UserName class="form-control" mdbInputDirective>
<button class="btn btn-indigo btn-lg btn-block waves-light" type="button" (click)="OnSubmit(UserName.value)" mdbWavesEffect>Send
    <i class="fa fa-paper-plane-o ml-1"></i>
</button>

但是我需要获取表单的所有值，所以我可以这样做：

<button class="btn btn-indigo btn-lg btn-block waves-light" type="button" (click)="OnSubmit(allFormValues)" mdbWavesEffect>Send
    <i class="fa fa-paper-plane-o ml-1"></i>
</button>

user: User;
ObSubmit(values) {
    user.UserName = values.UserName;
    user.Password = values.Password;
    ......
}

下面是完整的代码：

<div class="row">
  <div class="col-md-12 text-left">

    <form [formGroup]="subscriptionForm">
      <h3 style="color: gray; text-align: center;">Registration</h3>

      <div class="row">
        <div class="col-md-6">
          <div class="md-form">
            <i class="fa fa-user prefix grey-text"></i>
            <input type="text" formControlName="UserName" id="UserName" class="form-control" mdbInputDirective>
            <label …

我有两页，第一页有一个带有隐藏字段的表单，可以将参数发送到第二页。如果用户在带有隐藏字段的表单为空时转到第二页，我想返回一条错误消息，因此为此我尝试了该操作，但它不起作用：

@RequestMapping(value="/generate",method=RequestMethod.POST)
    public String FicheService(@ModelAttribute Movement movement,@RequestParam("nom") String nom, @RequestParam("number") Integer number,ModelMap model){


   if(nom=="" && number == null) { model.addAttribute("errorMessage",true);
                               return "firstPage";
                              }
   else { return "secondPage";}


}           

如何检查@RequestParam 是否为空？

我在 Amazon linux 2 实例上安装了 prometheus，这是我在用户数据中使用的配置：

cat << EOF > /etc/systemd/system/prometheus.service 
[Unit] 
Description=Prometheus Server 
Documentation=https://prometheus.io/docs/introduction/overview/ 
Wants=network-online.target
After=network-online.target

[Service] 
User=prometheus 
Restart=on-failure 

#Change this line if you download the  
#Prometheus on different path user 
ExecStart=/home/prometheus/prometheus/prometheus --config.file=/home/prometheus/prometheus/prometheus.yml --storage.tsdb.path=/app/prometheus/data

[Install] 
WantedBy=multi-user.target 
EOF

cat << EOF > /home/prometheus/prometheus/prometheus.yml 
# my global config 
global: 
  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute. 
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute. 
  # scrape_timeout …

我想在删除应用程序中的任何元素之前显示确认消息,我有:

<form:form name="formule" method="get" commandName="user"
    onsubmit="confirmDelete('${pageContext.request.contextPath}/delete_element')">       
     <form:input type="hidden" path="id" name="id" />
     <input type="submit" value="DELETE" />
</form:form>

功能 :

function confirmDelete(delUrl) {
    if (confirm("Are you sure ?")) {
        document.location = delUrl;
    }
}

这是控制器:

@RequestMapping(value = "/delete_element", method = RequestMethod.GET)
public String getInfo(@ModelAttribute User user,@RequestParam("id") int id,ModelMap model) {
    userservice.DeleteUser(id);
    return "ViewName";
}

这就是我得到的:函数的链接没有把我带到控制器所以没有发生任何事情,我们可以说javascript发送的请求没有到达服务器 ..是否真的很难在Spring MVC中集成任何东西像那样 ？!
