为 AlloyDB Omni 安装 PostGIS

AlloyDB Omni 不包含 PostGIS 扩展程序，但您可以按照本页中的说明将其手动添加到现有的 AlloyDB Omni 安装中，以添加对存储、编入索引和查询地理空间数据的支持。

准备工作

确保您已在系统上安装 AlloyDB Omni。

单服务器

将 PostGIS 添加到 AlloyDB Omni 安装

如需将 PostGIS 扩展程序添加到 AlloyDB Omni 安装，请按以下步骤操作：

  1. 查找已安装的 AlloyDB Omni 版本标签：

    Docker

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

    Podman

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

    输出类似于以下内容：

    AlloyDB Omni version: 15.5.5

    记下 AlloyDB Omni 版本号，您需要在下一步中使用此版本号。

  2. 设置 OMNI_VERSION 环境变量： 
    OMNI_VERSION=VERSION

    将 VERSION 替换为上一步中的完整数据库服务器版本，例如 15.5.3。

  3. 创建一个包含 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/*

   EOF
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 创建一个名为 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 扩展程序连接到数据库：

    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. 启用 PostGIS： 
    CREATE EXTENSION IF NOT EXISTS POSTGIS;

SELECT postgis_full_version();
     输出类似于以下内容： 
    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)"
