# Creación de manuales de procedimientos de Automation
Cada manual de procedimientos en Automatización, una herramienta de AWS Systems Manager, define una automatización. Los manuales de procedimientos de Automation definen las acciones que se realizan durante una automatización. En el contenido del manual de procedimientos, defina los parámetros de entrada, las salidas y las acciones que Systems Manager realiza en las instancias administradas y en los recursos de AWS.
Automation incluye varios manuales de procedimientos predefinidos que se pueden utilizar para realizar tareas comunes, como reiniciar una o más instancias de Amazon Elastic Compute Cloud (Amazon EC2), o crear una Amazon Machine Image (AMI). Sin embargo, los casos de uso pueden ir más allá de las capacidades de los manuales de procedimientos predefinidos. Si este es el caso, puede crear sus propios manuales de procedimientos y modificarlos de acuerdo con sus necesidades.
Un manual de procedimientos consta de acciones de automatización, parámetros para esas acciones y parámetros de entrada que usted especifica. El contenido de un manual de procedimientos está escrito en YAML o JSON. Si no conoce YAML ni JSON, recomendamos usar el diseñador visual o aprender más sobre cualquiera de los lenguajes de marcado antes de intentar crear su propio manual de procedimientos. Para obtener más información sobre el diseñador visual, consulte [Experiencia de diseño visual para manuales de procedimientos de automatización](automation-visual-designer.md).
Las siguientes secciones lo ayudarán a crear su primer manual de procedimientos.
## Identifique su caso de uso
El primer paso para crear un manual de procedimientos es identificar su caso de uso. Por ejemplo, ha programado el manual de procedimientos `AWS-CreateImage` de manera que se ejecute diariamente en todas las instancias de Amazon EC2 de producción. Al final del mes, decide tener más imágenes de las necesarias para los puntos de recuperación. Desde entonces, desea eliminar automáticamente la AMI más antigua de una instancia de Amazon EC2 al crear una AMI nueva. Para ello, crea un nuevo manual de procedimientos que hace lo siguiente:
1. Ejecuta la acción `aws:createImage` y especifica el ID de instancia en la descripción de la imagen.
1. Ejecuta la acción `aws:waitForAwsResourceProperty` para sondear el estado de la imagen hasta que sea `available`.
1. Después de que el estado de la imagen se haya establecido como `available`, la acción `aws:executeScript` ejecuta un script de Python personalizado que recopila los ID de todas las imágenes asociadas a su instancia de Amazon EC2. El script hace esto mediante el filtrado, con el ID de instancia en la descripción de la imagen que especificó en el momento de la creación. A continuación, el script ordena la lista de ID de imagen en función de la `creationDate` de la imagen y selecciona el ID de la AMI más antigua.
1. Por último, la acción `aws:deleteImage` se ejecuta para eliminar la AMI más antigua con el ID de la salida del paso anterior.
En este escenario, ya estaba usando el manual de procedimientos `AWS-CreateImage`, pero descubrió que el caso de uso requería más flexibilidad. Esta es una situación común, ya que puede haber superposición entre los manuales de procedimientos y las acciones de automatización. Como resultado, es posible que tenga que ajustar qué manuales de procedimientos o acciones usa para abordar su caso de uso.
Por ejemplo, las acciones `aws:executeScript` y `aws:invokeLambdaFunction` le permiten ejecutar scripts personalizados como parte de la automatización. A la hora de elegir una, es posible que prefiera `aws:invokeLambdaFunction` debido a los lenguajes adicionales de tiempo de ejecución compatibles. Sin embargo, es posible que prefiera `aws:executeScript` porque le permite crear contenido de script directamente en los manuales de procedimientos YAML y proporcionar contenido de script como archivos adjuntos para los manuales de procedimientos JSON. También podría considerar que `aws:executeScript` es más simple en cuanto a la configuración de AWS Identity and Access Management (IAM). Como utiliza los permisos proporcionados en el `AutomationAssumeRole`, `aws:executeScript` no requiere un rol de ejecución de la función de AWS Lambda adicional.
En cualquier escenario, una acción puede proporcionar más flexibilidad o funcionalidad adicional que la otra. Por lo tanto, recomendamos que revise los parámetros de entrada disponibles para el manual de procedimientos o la acción que desea utilizar para determinar cuál se ajusta mejor a su caso de uso y sus preferencias.
## Cómo configurar el entorno de desarrollo.
Después de identificar el caso de uso y los manuales de procedimientos predefinidos o las acciones de automatización que desea utilizar en el manual, debe configurar el entorno de desarrollo para el contenido del manual de procedimientos. Para desarrollar el contenido de su manual de procedimientos, recomendamos usar el AWS Toolkit for Visual Studio Code en lugar de la consola de documentos de Systems Manager.
El Toolkit for VS Code es una extensión de código abierto para Visual Studio Code (VS Code) que ofrece más características que la consola de documentos de Systems Manager. Entre las características útiles, se incluyen la validación de esquemas para YAML y JSON, los fragmentos para tipos de acciones de automatización y la compatibilidad con la capacidad de completar de manera automática para distintas opciones en YAML y JSON.
Para obtener más información acerca de la instalación de Toolkit for VS Code, consulte [Instalación de AWS Toolkit for Visual Studio Code](https://docs.aws.amazon.com/toolkit-for-vscode/latest/userguide/setup-toolkit.html). Para obtener más información acerca del uso de Toolkit for VS Code para desarrollar manuales de procedimientos, consulte [Uso de documentos de Automatización de Systems Manager](https://docs.aws.amazon.com/toolkit-for-vscode/latest/userguide/systems-manager-automation-docs.html) en la *Guía del usuario de AWS Toolkit for Visual Studio Code*.
## Desarrolle contenido para el manual de procedimientos
Con su caso de uso identificado y su entorno configurado, ya está listo para desarrollar el contenido para su manual de procedimientos. Su caso de uso y sus preferencias determinarán en gran medida las acciones de automatización o los manuales de procedimientos que utilice en el contenido de su manual. Algunas acciones admiten solo un subconjunto de parámetros de entrada si se comparan con otra acción que le permite llevar a cabo una tarea similar. Otras acciones tienen salidas específicas, como `aws:createImage`, donde algunas acciones le permiten definir sus propias salidas, tales como `aws:executeAwsApi`.
Si no está seguro de cómo se usa una acción concreta en el manual de procedimientos, le recomendamos que revise la entrada correspondiente a la acción en la [Referencia de acciones de Automatización de Systems Manager](automation-actions.md). También recomendamos que revise el contenido de manuales de procedimientos predefinidos para ver ejemplos reales de cómo se utilizan estas acciones. Para obtener más ejemplos de la aplicación real de los manuales de procedimientos, consulte [Ejemplos adicionales de manuales de procedimientos](automation-document-examples.md).
Con el fin de demostrar las diferencias en materia de simplicidad y flexibilidad que proporciona el contenido del manual de procedimientos, los siguientes tutoriales brindan un ejemplo de cómo aplicar revisiones a grupos de instancias de Amazon EC2 por etapas:
+ [Ejemplo 1: creación de manuales de procedimientos principal y secundario](automation-authoring-runbooks-parent-child-example.md): en este ejemplo, se utilizan dos manuales de procedimientos en una relación de manuales de tipo principal-secundario. El manual de procedimientos principal inicia una automatización de control de frecuencia del manual de procedimientos secundario.
+ [Ejemplo 2: manual de procedimientos con scripts](automation-authoring-runbooks-scripted-example.md): en este ejemplo, se muestra cómo puede realizar las mismas tareas del ejemplo 1 mediante la condensación del contenido en un único manual de procedimientos y a través del uso de scripts.
# Ejemplo 1: creación de manuales de procedimientos principal y secundario
En el siguiente ejemplo, se muestra cómo crear dos manuales de procedimientos que apliquen revisiones a grupos etiquetados de instancias de Amazon Elastic Compute Cloud (Amazon EC2) por etapas. Estos manuales de procedimientos se utilizan en una relación de manuales de tipo principal-secundario, por la cual se usa el manual de procedimientos principal para iniciar una automatización de control de frecuencia del manual de procedimientos secundario. Para obtener más información acerca de las automatizaciones de control de frecuencia, consulte [Ejecución de operaciones automatizadas a escala](running-automations-scale.md). Para obtener más información acerca de las acciones de automatización que se utilizan en este ejemplo, consulte [Referencia de acciones de Automatización de Systems Manager](automation-actions.md).
## Cree el manual de procedimientos secundario
En este manual de procedimientos de ejemplo, se aborda el siguiente escenario. Emily se desempeña como ingeniera en sistemas en AnyCompany Consultants, LLC. Debe configurar la aplicación de revisiones para grupos de instancias de Amazon Elastic Compute Cloud (Amazon EC2) que alojen bases de datos primarias y secundarias. Las aplicaciones acceden a estas bases de datos las 24 horas del día, por lo que una de las instancias de base de datos siempre debe estar disponible.
Ella decide que lo mejor que puede hacer es aplicar revisiones a las instancias por etapas. Primero se aplicará revisiones al grupo principal de instancias de base de datos y, luego, al grupo secundario. Además, para evitar incurrir en costos adicionales por dejar en ejecución instancias que se habían detenido anteriormente, Emily quiere que las instancias a las que se aplicaron revisiones se devuelvan a su estado original antes de que se apliquen las revisiones.
Emily identifica los grupos primarios y secundarios de instancias de base de datos a través de las etiquetas asociadas a las instancias. Ella decide crear un manual de procedimientos principal que inicia una automatización de control de frecuencia de un manual de procedimientos secundario. Al hacerlo, puede indicar como destino las etiquetas asociadas a los grupos primarios y secundarios de las instancias de base de datos y, a la vez, administrar la simultaneidad de las automatizaciones secundarias. Después de revisar los documentos disponibles de Systems Manager (SSM) para aplicar revisiones, elige el documento `AWS-RunPatchBaseline`. Mediante el uso de este documento de SSM, sus colegas pueden revisar la información de conformidad de las revisiones asociados una vez finalizada la operación de aplicación de revisiones.
Para empezar a crear el contenido de su manual de procedimientos, Emily revisa las acciones de automatización disponibles y comienza a crear el contenido del manual de procedimientos secundario de la siguiente manera:
1. En primer lugar, proporciona valores para el esquema y la descripción del manual de procedimientos, y define los parámetros de entrada para el manual de procedimientos secundario.
A través del parámetro `AutomationAssumeRole`, Emily y sus colegas pueden utilizar un rol de IAM existente que permite a Automation realizar las acciones en el manual de procedimientos en su nombre. Emily utiliza el parámetro `InstanceId` para determinar a qué instancia se le debe aplicar una revisión. De forma opcional, los parámetros `Operation`, `RebootOption` y `SnapshotId` se pueden utilizar para proporcionar valores a los parámetros del documento para `AWS-RunPatchBaseline`. Para evitar que se proporcionen valores no válidos a esos parámetros del documento, define los `allowedValues` como se necesiten.

1. Con los elementos de nivel superior definidos, Emily continúa con la creación de las acciones que componen los `mainSteps` del manual de procedimientos. El primer paso genera el estado actual de la instancia de destino especificada en el parámetro de entrada `InstanceId` mediante la acción `aws:executeAwsApi`. La salida de esta acción se utiliza en acciones posteriores.

```
------
1. En lugar de realizar un inicio manual y un seguimiento del estado original de cada instancia a la que se debe aplicar una revisión, Emily utiliza la salida de la acción anterior para bifurcar la automatización en función del estado de la instancia de destino. Esto permite que la automatización ejecute diferentes pasos dependiendo de las condiciones definidas en la acción `aws:branch` y, además, mejora la eficiencia general de la automatización sin intervención manual.
Si el estado de la instancia ya es `running`, la automatización continúa con la aplicación de revisiones a la instancia con el documento `AWS-RunPatchBaseline` mediante la acción `aws:runCommand`.
Si el estado de la instancia es `stopping`, la automatización realiza un sondeo para que la instancia alcance el estado `stopped` con la acción `aws:waitForAwsResourceProperty`, activa la instancia con la acción `executeAwsApi` y realiza un sondeo para que la instancia alcance el estado `running` antes de aplicarle revisiones.
Si el estado de la instancia es `stopped`, la automatización activa la instancia y realiza un sondeo para que alcance el estado `running` antes de aplicarle revisiones con las mismas acciones.

1. Una vez finalizada la operación de aplicación de revisiones, Emily quiere que la automatización devuelva la instancia de destino al mismo estado en que estaba antes de que comenzara la automatización. Para hacerlo, usa la salida de la primera acción otra vez. La automatización se bifurca en función del estado original de la instancia de destino con la acción `aws:branch`. Si, anteriormente, la instancia estaba en cualquier estado distinto de `running`, se detiene. De lo contrario, si el estado de la instancia es `running`, se termina la automatización.

## Crear el manual de procedimientos principal
En este manual de procedimientos de ejemplo, se continúa con el escenario descrito en la sección anterior. Ahora que Emily ha creado el manual de procedimientos secundario, comienza a generar el contenido del manual de procedimientos principal de la siguiente manera:
1. En primer lugar, proporciona valores para el esquema y la descripción del manual de procedimientos, y define los parámetros de entrada para el manual de procedimientos principal.
A través del parámetro `AutomationAssumeRole`, Emily y sus colegas pueden utilizar un rol de IAM existente que permite a Automation realizar las acciones en el manual de procedimientos en su nombre. Emily utiliza los parámetros `PatchGroupPrimaryKey` y `PatchGroupPrimaryValue` para especificar la etiqueta asociada al grupo principal de instancias de base de datos a las cuales se aplicarán revisiones. Utiliza los parámetros `PatchGroupSecondaryKey` y `PatchGroupSecondaryValue` para especificar la etiqueta asociada al grupo secundario de instancias de base de datos a las cuales se aplicarán revisiones.

1. Con los elementos de nivel superior definidos, Emily continúa con la creación de las acciones que componen los `mainSteps` del manual de procedimientos.
La primera acción inicia una automatización de control de frecuencia con el manual de procedimientos secundario que acaba de crear y que indica como destino instancias asociadas a la etiqueta que se especificó en los parámetros de entrada `PatchGroupPrimaryKey` y `PatchGroupPrimaryValue`. Utiliza los valores proporcionados para los parámetros de entrada con el fin de especificar la clave y el valor de la etiqueta asociada al grupo principal de instancias de base de datos a las que desea aplicar revisiones.
Una vez finalizada la primera automatización, la segunda acción inicia otra automatización de control de frecuencia con el manual de procedimientos secundario que indica como destino instancias asociadas a la etiqueta que se especificó en los parámetros de entrada `PatchGroupSecondaryKey` y `PatchGroupSecondaryValue`. Utiliza los valores proporcionados para los parámetros de entrada con el fin de especificar la clave y el valor de la etiqueta asociada al grupo secundario de instancias de base de datos a las que desea aplicar revisiones.

# Ejemplo 2: manual de procedimientos con scripts
En este manual de procedimientos de ejemplo, se aborda el siguiente escenario. Emily se desempeña como ingeniera en sistemas en AnyCompany Consultants, LLC. Anteriormente, creó dos manuales de procedimientos que se utilizan en una relación de manuales de tipo principal-secundario a fin de aplicar parches a grupos de instancias de Amazon Elastic Compute Cloud (Amazon EC2) que alojan bases de datos primarias y secundarias. Las aplicaciones acceden a estas bases de datos las 24 horas del día, por lo que una de las instancias de base de datos siempre debe estar disponible.
Teniendo en cuenta este requisito, creó una solución que aplica parches a las instancias en etapas mediante el documento `AWS-RunPatchBaseline` de Systems Manager (SSM). Mediante el uso de este documento de SSM, sus colegas pueden revisar la información de conformidad de los parches asociados una vez finalizada la operación de aplicación de parches.
Primero se aplican parches al grupo principal de instancias de base de datos y, luego, al grupo secundario. Además, para evitar incurrir en costos adicionales por dejar en ejecución instancias que se habían detenido anteriormente, Emily se aseguró de que la automatización devolviera las instancias a las que se aplicaron parches a su estado original antes de que se aplicaran los parches. Emily utilizó etiquetas asociadas a los grupos primarios y secundarios de instancias de base de datos para identificar a qué instancias se deben aplicar parches en el orden deseado.
Su solución automatizada existente funciona, pero, de ser posible, quiere mejorarla. Para ayudar con el mantenimiento del contenido del manual de procedimientos y facilitar la solución de problemas, le gustaría condensar la automatización en un solo manual de procedimientos y simplificar el número de parámetros de entrada. Además, le gustaría evitar la creación de múltiples automatizaciones secundarias.
Después de que Emily revisa las acciones de automatización disponibles, determina que puede mejorar su solución mediante la acción `aws:executeScript` para ejecutar sus scripts de Python personalizados. Ahora, comienza a crear el contenido del manual de procedimientos de la siguiente manera:
1. En primer lugar, proporciona valores para el esquema y la descripción del manual de procedimientos, y define los parámetros de entrada para el manual de procedimientos principal.
A través del parámetro `AutomationAssumeRole`, Emily y sus colegas pueden utilizar un rol de IAM existente que permite a Automation realizar las acciones en el manual de procedimientos en su nombre. A diferencia del [ejemplo 1](automation-authoring-runbooks-parent-child-example.md), ahora el parámetro `AutomationAssumeRole` es obligatorio en lugar de opcional. Debido a que este manual de procedimientos incluye acciones `aws:executeScript`, siempre se requiere un rol de servicio de AWS Identity and Access Management (IAM) (o rol de asunción). Este requisito es necesario, ya que algunos de los scripts de Python especificados para las acciones llaman las operaciones de la API de AWS.
Emily utiliza los parámetros `PrimaryPatchGroupTag` y `SecondaryPatchGroupTag` para especificar las etiquetas asociadas al grupo principal y secundario de instancias de base de datos a las cuales se aplicarán parches. Para simplificar los parámetros de entrada necesarios, decide utilizar los parámetros `StringMap` en lugar de varios parámetros `String`, como hizo con el manual de procedimientos del ejemplo 1. De forma opcional, los parámetros `Operation`, `RebootOption` y `SnapshotId` se pueden utilizar para proporcionar valores a los parámetros del documento para `AWS-RunPatchBaseline`. Para evitar que se proporcionen valores no válidos a esos parámetros del documento, define los `allowedValues` como se necesiten.

1. Con los elementos de nivel superior definidos, Emily continúa con la creación de las acciones que componen los `mainSteps` del manual de procedimientos. El primer paso recopila los ID de todas las instancias asociadas a la etiqueta especificada en el parámetro `PrimaryPatchGroupTag` y genera un parámetro `StringMap` que contiene el ID de instancia y su estado actual. La salida de esta acción se utiliza en acciones posteriores.
Tenga en cuenta que el parámetro de entrada `script` no es compatible con los manuales de procedimientos JSON. Los manuales de procedimientos JSON deben proporcionar contenido de script a través del parámetro de entrada `attachment`.

1. Una vez finalizada la operación de aplicación de parches, Emily quiere que la automatización devuelva las instancias de destino asociadas a la etiqueta que se especificó en el parámetro `PrimaryPatchGroupTag` al mismo estado en que estaban antes de que se iniciara la automatización. Para hacerlo, usa otra vez la salida de la primera acción en un script. En función del estado original de la instancia de destino, si la instancia estaba anteriormente en un estado distinto de `running`, se detiene. En cambio, si el estado de la instancia es `running`, el script sigue recorriendo las instancias restantes.

Para obtener más información acerca de las acciones de automatización que se utilizan en este ejemplo, consulte [Referencia de acciones de Automatización de Systems Manager](automation-actions.md).
# Ejemplos adicionales de manuales de procedimientos
El siguiente manual de procedimientos de ejemplo demuestra cómo puede usar las acciones de automatización de AWS Systems Manager para automatizar tareas comunes de implementación, solución de problemas y mantenimiento.
**nota**
Los manuales de procedimientos de ejemplo de esta sección se proporcionan para demostrar cómo puede crear manuales de procedimientos personalizados para satisfacer sus necesidades operativas específicas. Estos manuales de procedimientos no están diseñados para su uso en entornos de producción tal como están. Sin embargo, puede personalizarlos para su propio uso.

# Implementación de la arquitectura de VPC y de controladores de dominio de Microsoft Active Directory
Para aumentar la eficiencia y estandarizar las tareas comunes, puede elegir automatizar las implementaciones. Esto resulta útil si suele implementar la misma arquitectura en varias cuentas y de manera regular Regiones de AWS. La automatización de las implementaciones de arquitectura también puede reducir la posibilidad de que se produzcan los errores humanos inherentes a los procesos manuales. AWS Systems Manager Las acciones de Automation pueden ayudarlo a lograrlo. Automatización es una herramienta de AWS Systems Manager.
El siguiente manual de procedimientos de AWS Systems Manager de ejemplo realiza estas acciones:
+ Recupera la última Amazon Machine Image (AMI) de Windows Server 2016 con Parameter Store de Systems Manager para usarla al momento de lanzar las instancias de EC2 que se configurarán como controladores de dominio. Parameter Store es una herramienta de AWS Systems Manager.
+ Utiliza la acción de automatización `aws:executeAwsApi` a fin de llamar varias operaciones de la API de AWS para crear la arquitectura de VPC. Las instancias del controlador de dominio se inician en subredes privadas y se conectan a Internet mediante una puerta de enlace NAT. Esto permite que el SSM Agent en las instancias acceda a los puntos de enlace necesarios de Systems Manager.
+ Utiliza la acción de automatización `aws:waitForAwsResourceProperty` a fin de confirmar que las instancias lanzadas por la acción anterior estén `Online` para AWS Systems Manager.
+ Utiliza la acción de automatización `aws:runCommand` para configurar las instancias lanzadas como controladores de dominio de Microsoft Active Directory.

# Restauración de un volumen raíz a partir de la última instantánea
El sistema operativo en un volumen raíz puede dañarse por varias razones. Por ejemplo, después de una operación de revisióno, las instancias podrían arrancar de manera incorrecta debido a un kernel o un registro dañado. La automatización de tareas comunes de solución de problemas, como la restauración de un volumen raíz a partir de la última instantánea tomada antes de la operación de aplicación de revisiones, puede reducir el tiempo de inactividad y agilizar los esfuerzos de solución de problemas. AWS Systems Manager Las acciones de Automation pueden ayudarlo a lograrlo. Automatización es una herramienta de AWS Systems Manager.
El siguiente manual de procedimientos de AWS Systems Manager de ejemplo realiza estas acciones:
+ Utiliza la acción de automatización `aws:executeAwsApi` para recuperar detalles del volumen raíz de la instancia.
+ Utiliza la acción de automatización `aws:executeScript` para recuperar la última instantánea del volumen raíz.
+ Utiliza la acción de automatización `aws:branch` para continuar la automatización si se encuentra una instantánea para el volumen raíz.

# Creación de una AMI y de una copia entre regiones
La creación de una Amazon Machine Image (AMI) a partir de una instancia es un proceso que se utiliza para realizar copias de seguridad y tareas de recuperación. En una arquitectura de recuperación de desastres, también puede copiar una AMI en otra Región de AWS, si así lo desea. La automatización de tareas de mantenimiento habituales puede reducir el tiempo de inactividad si un problema requiere la conmutación por error. AWS Systems Manager Las acciones de Automation pueden ayudarlo a lograrlo. Automatización es una herramienta de AWS Systems Manager.
El siguiente manual de procedimientos de AWS Systems Manager de ejemplo realiza estas acciones:
+ Utiliza la acción de automatización `aws:executeAwsApi` para crear una AMI.
+ Utiliza la acción de automatización `aws:waitForAwsResourceProperty` para confirmar la disponibilidad de la AMI.
+ Utiliza la acción de automatización `aws:executeScript` para copiar la AMI en la región de destino.
