Installa PostGIS per AlloyDB Omni

AlloyDB Omni non include l'estensione PostGIS, ma puoi aggiungerla manualmente a un'installazione AlloyDB Omni esistente seguendo le istruzioni riportate in questa pagina per aggiungere il supporto per l'archiviazione, l'indicizzazione e le query dei dati geospaziali.

Prima di iniziare

Assicurati di aver installato AlloyDB Omni sul tuo sistema.

Single-server

Aggiungi PostGIS all'installazione di AlloyDB Omni

Per aggiungere l'estensione PostGIS all'installazione di AlloyDB Omni, segui questi passaggi:

Trova le etichette delle versioni di AlloyDB Omni installate:
Docker
```
docker run --rm -it  google/alloydbomni cat VERSION.txt
```
Podman
```
podman run --rm -it  google/alloydbomni cat VERSION.txt
```
L'output è simile al seguente:
```
AlloyDB Omni version: 15.5.5
```
Prendi nota del numero di versione di AlloyDB Omni, che ti servirà nel passaggio successivo.
Imposta la variabile di ambiente OMNI_VERSION:
```
OMNI_VERSION=VERSION
```
Sostituisci VERSION con la versione completa del server di database del passaggio precedente, ad esempio 15.5.3.

Crea un nuovo contenitore AlloyDB Omni che includa PostGIS:

Crea un nuovo contenitore con AlloyDB Omni denominato my-omni-postgis:

Docker

docker run --name my-omni-postgis  -e POSTGRES_PASSWORD=NEW_PASSWORD  -d google/alloydbomni-with-postgis:OMNI_VERSION

Podman

podman run --name my-omni-postgis  -e POSTGRES_PASSWORD=NEW_PASSWORD  -d google/alloydbomni-with-postgis:OMNI_VERSION

Connettiti al database con l'estensione PostGIS:

Docker

docker exec -it my-omni-postgis psql -h localhost -U postgres

Podman

podman exec -it my-omni-postgis psql -h localhost -U postgres

Attiva PostGIS:

CREATE EXTENSION IF NOT EXISTS POSTGIS;

SELECT postgis_full_version();

L'output è simile al seguente:
