Usa le utility Python di Oracle Cloud Infrastructure Object Storage per le operazioni in blocco

Introduzione

Oracle Cloud Infrastructure (OCI) Object Storage consente ai clienti di memorizzare in modo sicuro qualsiasi tipo di dati nel formato nativo. Grazie alla ridondanza integrata, OCI Object Storage è la soluzione ideale per creare applicazioni moderne che richiedono scalabilità e flessibilità, in quanto può essere utilizzato per consolidare più origini dati a scopo di analitica, backup o archiviazione.

Lo storage degli oggetti OCI è fondamentale per i carichi di lavoro cloud; la sua elasticità, scalabilità, affidabilità ed efficienza dei costi lo hanno reso lo storage primario per i dati non strutturati nel cloud. A causa della sua popolarità, esiste un vasto ecosistema di strumenti per lavorare con OCI Object Storage. Questo tutorial è il primo della serie di "strumenti di potenza" che mira a fornire un percorso per gli utenti di familiarizzare con i vari strumenti disponibili e come utilizzarli nei loro carichi di lavoro.

Questa prima esercitazione introduce gli script di esempio disponibili in GitHub utilizzando l'SDK Python con OCI Object Storage per le operazioni in blocco.

Destinatari

DevOps ingegneri, sviluppatori, amministratori e utenti dello storage degli oggetti OCI, responsabili IT, utenti avanzati OCI e amministratori delle applicazioni.

Obiettivo

Utilizzare gli esempi di script Python per gestire operazioni in blocco nello storage degli oggetti OCI, ad esempio il ripristino, l'eliminazione, la copia, la ridenominazione e l'elenco delle informazioni sugli oggetti.

Prerequisiti

Account OCI.
File di configurazione funzionante nella directory home in una sottodirectory denominata .oci. Per ulteriori informazioni, vedere Impostazione del file di configurazione.
Accesso a un bucket di storage degli oggetti OCI.
Autorizzazioni utente in OCI per utilizzare lo storage degli oggetti OCI, avere accesso per gestire gli oggetti in almeno 1 bucket. Per ulteriori informazioni, vedere Criteri comuni e Riferimento criteri.
Un ambiente di esecuzione: accesso a OCI Cloud Shell, un'istanza OCI Linux.
Pacchetto Git installato nell'ambiente di esecuzione e familiarità con i comandi git.
Python 3 installato.
Familiarità con l'uso dei moduli Python e Python.

Task 1: Impostare l'ambiente

Installare il pacchetto del kit di sviluppo software OCI (SDK).
```
pip3 install --user oci
```

Duplicare il repository SDK OCI.

$ git clone https://github.com/oracle/oci-python-sdk

Nota: si tratta di script di esempio che utilizzano l'SDK Python OCI, non sono applicazioni Oracle ufficiali e non sono gestiti o supportati da Oracle. Poiché si tratta di esempi, è possibile esaminarli, aggiornarli e personalizzarli per il caso d'uso nel proprio repository software.

Passare alla directory di esempio. Se installato nella directory home, eseguire il comando seguente.
```
cd $HOME/oci-python-sdk/examples/object_storage
```

Task 2: Uso dello script di ripristino di massa degli oggetti

Lo script di ripristino di massa ripristina gli oggetti archiviati nel bucket di origine con thread paralleli.

Eseguire lo script di ripristino di massa senza argomenti per visualizzare gli argomenti richiesti.

$ python object_storage_bulk_restore.py
Source bucket parameter is required !!!

usage: object_storage_bulk_restore.py [-h] [-t CONFIG_PROFILE] [-p PROXY]
                                      [-ip] [-dt] [-c CONFIG_FILE]
                                      [-sb SOURCE_BUCKET]
                                      [-sp SOURCE_PREFIX_INCLUDE]
                                      [-sr SOURCE_REGION]
                                      [-sn SOURCE_NAMESPACE]

optional arguments:
  -h, --help            show this help message and exit
  -t CONFIG_PROFILE     Config file section to use (tenancy profile)
  -p PROXY              Set Proxy (i.e. www-proxy-server.com:80)
  -ip                   Use Instance Principals for Authentication
  -dt                   Use Delegation Token for Authentication
  -c CONFIG_FILE        Config File (default=~/.oci/config)
  -sb SOURCE_BUCKET     Source Bucket Name

                        Source Prefix Include
  -sr SOURCE_REGION     Source Region
  -sn SOURCE_NAMESPACE  Source Namespace (Default current connection)

Nota: questa esercitazione utilizzerà il file di configurazione per tutti gli script. Gli script verranno impostati automaticamente sull'area elencata nel file di configurazione, se non è specificata come argomento di script.

Eseguire lo script senza utilizzare l'argomento prefisso. In questo modo verranno ripristinati tutti gli oggetti di archivio.

Task 3: Uso dello script di eliminazione di massa oggetto

Lo script di eliminazione di massa degli oggetti elimina gli oggetti da un bucket con l'opzione di filtro.

Eseguire lo script senza argomenti per visualizzare l'uso.

Nota: l'esecuzione dello script senza un prefisso di inclusione o esclusione comporta l'eliminazione di tutti gli elementi nel bucket.

Eseguire lo script di eliminazione di massa e impostare un prefisso di inclusione, rivedere l'output e rispondere al prompt y/N.

Nota: tutti gli oggetti nel prefisso/cartella e nei prefissi secondari/cartelle secondarie verranno eliminati, prestare attenzione quando si esegue il comando. Se non viene trovata alcuna corrispondenza, tutti gli elementi nel bucket verranno eliminati.

Task 4: Uso dello script di ridenominazione di massa oggetto

Lo script di ridenominazione di massa può essere utilizzato per rinominare gli oggetti o per spostarli in una cartella/prefisso diverso. È importante capire che lo script di ridenominazione cambia semplicemente i metadati del nome sull'oggetto, non è una copia dell'oggetto, è solo una ridenominazione.

Eseguire lo script di ridenominazione in blocco dell'oggetto senza argomenti per visualizzare i parametri richiesti.

Task 5: Uso dello script di copia di massa oggetto

Lo script di copia di massa copia gli oggetti tra bucket, può essere utilizzato per copiare oggetti tra bucket in aree diverse o in tenancy diverse. Questa esercitazione illustra una copia tra bucket nella stessa tenancy in tutte le aree, un bucket in us-ashburn-1 e un altro bucket in us-phoenix-1. Se si desidera utilizzare lo script tra le tenancy, vedere Accesso alle risorse di storage degli oggetti nelle tenancy.

Nota: sono disponibili strumenti più efficaci per copiare in blocco gli oggetti tra i bucket, ad esempio Rclona o Replica storage degli oggetti.

Eseguire lo script di copia di massa dell'oggetto senza argomenti per comprendere i parametri richiesti.
