在ansible

Question

我写的是一个安全代码。它执行两项任务，首先是将配置文件复制到组中的目标实例。其次是运行该配置文件来安装应用程序。

我正在以编程方式创建配置文件和库存，以便将相同的后缀添加到configfile name＆amp;库存中的组名：

Configfile name example :            Equivalent group names:
myappconf1                             [myapp1]
                                       hostname
myappconf2                             [myapp2]
                                       hostname

这是复制文件

的代码

hosts: all
tasks:
name: Copy file.role1 to host1
 copy: src=/tmp/myconf1 dest=/tmp
 when:
  - "'myapp1' in group_names"


name: Copy Config File two to  to Ldap2
 copy: src=/tmp/myconf2 dest=/tmp
 when:
  - "'myapp2' in group_names"

这是运行配置文件

的代码

hosts: myapp1
tasks:
  - command: "/tmp/mainapp/update.sh -f myappconf1"

hosts: myapp2
tasks:
  - command: "/tmp/mainapp/update.sh -f myappconf1"

但是根据用户输入，可以创建不确定数量的conf文件和组，所以我想以编程方式执行任务。 所需代码可能类似：

[task for copying file]
hosts: ~(myapp)
tasks:
- copy: copy the appropriate file to the host 
        example: copy myappconf4 to myapp4
- command: run the commmand with appropirate file
           example: for myapp3, command: /tmp/mainapp/update.sh -f myappconf3

有人可以建议我使用什么来使我的代码更通用和有效吗？

Answer 1

你可以使用像这样的组变量，

/**
 * This example adds a new remarketing list audience to the account and
 * retrieves the associated remarketing tag code.
 */
class AddAudience {

  public static function runExample(AdWordsServices $adWordsServices,
      AdWordsSession $session) {
    $userListService =
        $adWordsServices->get($session, AdwordsUserListService::class);
    $conversionTrackerService =
        $adWordsServices->get($session, ConversionTrackerService::class);

    // Create a conversion type (tag).
    $conversionType = new UserListConversionType();
    $conversionType->setName('Mars cruise customers #' . uniqid());

    // Create a basic user list.
    $userList = new BasicUserList();
    $userList->setName('Mars cruise customers #' . uniqid());
    $userList->setConversionTypes([$conversionType]);

    // Set additional settings (optional).
    $userList->setDescription(
        'A list of mars cruise customers in the last year');
    $userList->setStatus(UserListMembershipStatus::OPEN);
    $userList->setMembershipLifeSpan(365);

    // Create a user list operation and add it to the list.
    $operations = [];
    $operation = new UserListOperation();
    $operation->setOperand($userList);
    $operation->setOperator(Operator::ADD);
    $operations[] = $operation;

    // Create the user list on the server.
    $userList = $userListService->mutate($operations)->getValue()[0];

    // Create the selector.
    $selector = new Selector();
    $selector->setFields(['Id']);
    $selector->setPredicates(
        [new Predicate('Id', PredicateOperator::IN,
            [$userList->getConversionTypes()[0]->getId()])]);

    // Retrieve the conversion tracker and print out its information.
    $conversionTracker =
        $conversionTrackerService->get($selector)->getEntries()[0];
    printf("Audience with name '%s' and ID %d was added.\n",
        $userList->getName(), $userList->getId());
    printf("Conversion tracker snippet:\n%s\n",
        $conversionTracker->getSnippet()); }

然后将第二个文件夹用于第二个应用程序

#File : "myapp1/group_vars/all/vars_file.yml"
# Application settings
app_name: "myapp1"
copy_file: "myapp1conf1"
.
.
# other variables used for myapp1

并在您的代码中修改如下，

#File : "myapp2/group_vars/all/vars_file.yml"
# Application settings
copy_file: "myapp2conf2"
.
.
# other variables used for myapp2

现在根据环境使用播放时间内的用户输入，如下所示

hosts: all
-tasks
    -name: Copy file.role1 to host1
     copy: src=/tmp/{{ copy_file }} dest=/tmp

    -name : execute script
     command: "/tmp/mainapp/update.sh -f {{ app_name }}"

Answer 2

我用以下格式的python代码填充变量来解决问题：

[myapp]
host1 conf_file="myappconf1"
host2 conf_file="myappconf2"

然后在我的代码中，我将变量用于复制和运行配置文件任务。
