Visualizzazione di un manifest

A ogni deployment corrisponde un manifest. Un manifest è una proprietà di sola lettura che descrive tutte le risorse del deployment e viene creato automaticamente a ogni nuovo deployment. I manifest non sono modificabili dopo essere stati creati. Un file manifest non è uguale a un file di configurazione, ma viene creato in base al file di configurazione.

Prima di iniziare

Struttura del manifest

Un manifest fornisce tre visualizzazioni di un deployment:

  • La configurazione iniziale
  • La configurazione completamente valutata dopo che tutti i modelli e le importazioni sono stati espansi
  • Il layout del deployment, che descrive tutte le risorse per il deployment in una struttura gerarchica.

Configurazione originale

La configurazione originale è la configurazione che hai fornito al deployment, prima di qualsiasi espansione del modello. La configurazione iniziale è indicata dalla proprietà config:

config: |
  imports:
  - path: vm-template.jinja
  - path: network-template.jinja
  - path: firewall-template.jinja
  - path: compute-engine-template.jinja

  resources:
  - name: compute-engine-setup
    type: compute-engine-template.jinja

Configurazione espansa

La configurazione espansa è una descrizione completa del deployment, incluse tutte le risorse e le relative proprietà, dopo l'elaborazione di tutti i modelli. Questo è lo stato finale della configurazione.

La parte della configurazione espansa del file manifest è indicata dalla proprietà expandedConfig:

expandedConfig: |
  resources:
  - name: datadisk-example-config-with-templates
    properties:
      sizeGb: 100

      zone: us-central1-a
    type: compute.v1.instance

Modelli importati

La proprietà imports nel file manifest mostra i contenuti di tutti i modelli che hai importato per questa configurazione. La sezione delle importazioni del file manifest è indicata dalla sezione imports:

imports:
- content: |
    resources:
    - name: {{ env["name"] }}
      type: compute.v1.instance
      properties:

Layout

Il layout è una struttura dell'implementazione e delle sue risorse, che mostra i nomi e i tipi delle risorse.

Utilizza il layout per visualizzare la struttura del deployment, le proprietà del modello impostate durante il deployment iniziale e altre informazioni sulla configurazione prima dell'espansione.

Nel file manifest puoi vedere il layout nella proprietà layout:

layout: |
  resources:
  - name: compute-engine-setup
    resources:
    - name: the-first-vm
      properties:
        machineType: f1-micro
        network: a-new-network
        zone: us-central1-f
      resources:
      - name: the-first-vm
        type: compute.v1.instance
      type: vm-template.jinja
    - name: the-second-vm
      properties:
        machineType: g1-small
        network: a-new-network
        zone: us-central1-f
      resources:
      - name: the-second-vm
        type: compute.v1.instance
      type: vm-template.jinja
    - name: a-new-network
      resources:
      - name: a-new-network
        type: compute.v1.network
      type: network-template.jinja
    - name: a-new-network-firewall
      properties:
        network: a-new-network
      resources:
      - name: a-new-network-firewall
        type: compute.v1.firewall
      type: firewall-template.jinja
    type: compute-engine-template.jinja

Identifica un manifest

Puoi identificare un manifest dal suo ID univoco, nel formato manifest-TIMESTAMP. Ad esempio:

manifest-1436393348324

In genere, puoi ottenere l'ID manifest ottenendo informazioni sul deployment corrispondente o elencando i manifest per un deployment.

gcloud

Con Google Cloud CLI, utilizza il sottocomando deployments describe:

gcloud deployment-manager deployments describe example-deployment

gcloud restituisce una risposta simile alla seguente:

id: '7428522736135856060'
manifest: https://www.googleapis.com/deploymentmanager/v2beta1/projects/myproject/global/deployments/example-deployment/manifests/manifest-1436393348324
name: example-deployment
resources:
NAME    TYPE      ID     STATE   ERRORS
...

API

Nell'API, effettua una richiesta GET, specificando nella richiesta il nome del deployment:

GET https://www.googleapis.com/deploymentmanager/v2beta1/projects/myproject/global/deployments/example-deployment-with-config

Dovresti ricevere una risposta simile alla seguente:

{
 "id": "5899501332770090517",
 "creationTimestamp": "2015-03-30T15:40:58.809-07:00",
 "name": "example-deployment-with-config",
 "fingerprint": "",
 "manifest": "https://www.googleapis.com/deploymentmanager/v2/projects/myproject/global/deployments/example-deployment-with-config/manifests/manifest-1427755258810-2b3498d9-530b-4f8e-b014-0342d3c9c66b",
 "state": "DEPLOYED"
}

Visualizzare un manifest

Per visualizzare un manifest, puoi effettuare una richiesta get() a una risorsa manifest oppure tramite la console Google Cloud o gcloud.

Console

Per visualizzare il manifest di un deployment nella console Google Cloud:

  1. Vai alla pagina Deployment nella console Google Cloud.
  2. Nell'elenco, fai clic sul deployment che vuoi visualizzare.
  3. Nei dettagli del deployment, fai clic su Panoramica.

gcloud

Con Google Cloud CLI, visualizza il manifest completo utilizzando il comando manifests describe. Il comando elenca sia il manifest completo che il layout:

gcloud deployment-manager manifests describe manifest-1436393348324 \
    --deployment example-config-with-templates

gcloud restituisce una risposta simile alla seguente:
