我正在尝试将 postgis 安装到 postgres 容器中。Dockerfile:

FROM postgres:9.6.4-alpine

RUN apk update \
    && apk add -u postgresql-9.6-postgis-2.4 postgresql-9.6-postgis-2.4-scripts \
    && rm -rf /var/lib/apt/lists/*

COPY ./scripts/postgis.sh  /docker-entrypoint-initdb.d/postgis.sh

postgis.sh:

#!/bin/sh

for DB in $(psql -t -c  "SELECT datname from pg_database where datname = 'backend'"); do
    echo "Loading PostGIS extensions into $DB"
    "${psql[@]}" --dbname="$DB" <<-'EOSQL'
        CREATE EXTENSION IF NOT EXISTS postgis;
EOSQL
done

我收到了这个错误:

错误:不可满足的约束:postgresql-9.6-postgis-2.4(缺失):要求:world[postgresql-9.6-postgis-2.4] postgresql-9.6-postgis-2.4-scripts(缺失):要求:world[postgresql-9.6 -postgis-2.4-scripts] 命令 '/bin/sh -c apk update && apk add -u postgresql-9.6-postgis-2.4 postgresql-9.6-postgis-2.4-scripts && rm -rf /var/lib/apt/ lists/*' 返回一个非零代码:2

我发现了类似的问题,例如:

  1. 错误:无法满足的约束:在 alpine 中安装软件包时
  2. 错误:无法满足的约束 - 在 php:7-fpm-alpine

但这并没有解决我的问题。如何使用 apk 将 postgis 扩展添加到我的 postgres 容器中?

Postgis软件包仅在 edge alpine repo 中可用,而不是在稳定版中。这就是为什么您会收到“不可满足的约束”错误。

但无论如何,您可以postgis从 edge repo 安装:

# echo "http://dl-cdn.alpinelinux.org/alpine/edge/testing" >> /etc/apk/repositories

# apk update
fetch http://dl-cdn.alpinelinux.org/alpine/v3.5/main/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.5/community/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/edge/testing/x86_64/APKINDEX.tar.gz
WARNING: This apk-tools is OLD! Some packages might not function properly.

# apk search --no-cache postgis

WARNING: This apk-tools is OLD! Some packages might not function properly.
postgis-dev-2.4.1-r1
postgis-2.4.1-r1
postgis-doc-2.4.1-r1

所以,最终结果Dockerfile是:

FROM postgres:9.6.4-alpine

RUN echo "http://dl-cdn.alpinelinux.org/alpine/edge/testing" >> /etc/apk/repositories

RUN apk update \
    && apk add -u postgis \
    && rm -rf /var/lib/apt/lists/*

COPY ./scripts/postgis.sh  /docker-entrypoint-initdb.d/postgis.sh

2020 年 1 月 23 日更新:

从 Alpine 版本 3.11 开始, Postgis可在主要和社区存储库中使用:

/ # cat /etc/os-release
NAME="Alpine Linux"
ID=alpine
VERSION_ID=3.11.3
PRETTY_NAME="Alpine Linux v3.11"
HOME_URL="https://alpinelinux.org/"
BUG_REPORT_URL="https://bugs.alpinelinux.org/"
/ #
/ # apk search --no-cache postgis
fetch http://dl-cdn.alpinelinux.org/alpine/v3.11/main/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.11/community/x86_64/APKINDEX.tar.gz
postgis-3.0.0-r1
postgis-doc-3.0.0-r1

对于 Alpine 版本 3.11 及更高版本,您不需要使用边缘 repo 测试分支。

老的:

apk add --no-cache curl jq python py-pip

新的:

这很奇怪,但在我的情况下,解决方案就像运行一样简单:

sudo systemctl restart docker

...在您运行 docker 容器的机器上
