為 AlloyDB Omni 安裝 PostGIS

選取說明文件版本：

AlloyDB Omni 不包含 PostGIS 擴充功能，但您可以按照本頁的說明，手動將其新增至現有的 AlloyDB Omni 安裝項目，以便支援儲存、建立索引及查詢地理空間資料。

事前準備

確認您已在系統上安裝 AlloyDB Omni。

單一伺服器

在 AlloyDB Omni 安裝中新增 PostGIS

如要在 AlloyDB Omni 安裝中新增 PostGIS 擴充功能，請按照下列步驟操作：

  1. 找出已安裝的 AlloyDB Omni 版本標籤：

    Docker

    docker run --rm -it  google/alloydbomni cat VERSION.txt

    Podman

    podman run --rm -it  google/alloydbomni cat VERSION.txt

    輸出結果會與下列內容相似：

    AlloyDB Omni version: 15.5.5

    記下 AlloyDB Omni 版本號碼，下一個步驟會用到。

  2. 設定 OMNI_VERSION 環境變數： 
    OMNI_VERSION=VERSION

    將 VERSION 替換為上一步的完整資料庫伺服器版本，例如 15.5.5。

  3. 建立包含 PostGIS 的新 AlloyDB Omni 容器：

    Docker

       mkdir ~/alloydb-omni-postgis
   tee -a ~/alloydb-omni-postgis/Dockerfile << EOF
   ARG OMNI_VERSION
   FROM postgres:15-bookworm AS postgres

   RUN apt-get update && \
   apt-get install -y --no-install-recommends \
   postgresql-15-postgis-3 && \
   apt-get purge -y --auto-remove && \
   rm -rf /var/lib/apt/lists/*

cd ~/alloydb-omni-postgis
sudo podman build --build-arg OMNI_VERSION=$OMNI_VERSION --tag google/alloydbomni-with-postgis:$OMNI_VERSION .
  4. 使用 AlloyDB Omni 建立名為 my-omni-postgis 的新容器：

    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
  5. 使用 PostGIS 擴充功能連線至資料庫：

    Docker

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

    Podman

    podman exec -it my-omni-postgis psql -h localhost -U postgres
  6. 啟用 PostGIS： 
    CREATE EXTENSION IF NOT EXISTS POSTGIS;

SELECT postgis_full_version();
     輸出內容如下所示： 
    postgis_full_version
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
POSTGIS="3.4.2 c19ce56" [EXTENSION] PGSQL="150" GEOS="3.11.1-CAPI-1.17.1" PROJ="9.1.1 NETWORK_ENABLED=OFF URL_ENDPOINT= USER_WRITABLE_DIRECTORY=/var/lib/postgresql/.local/share/proj DATABASE_PATH=/usr/share/proj/proj.db" LIBXML="2.9.14" LIBJSON="0.16" LIBPROTOBUF="1.4.1" WAGYU="0.5.0 (Internal)"
