Windows Server 2016上Windows容器中的PostgreSQL出现问题

我正在试着跑 PostgreSQL 10.6.1 在docker容器中(基本图像是 mcr.microsoft.com/windows/servercore:ltsc2016 )它应该在WindowsServer2016数据中心(1607版本,内部版本14393.2759)上运行。

initdb 然后运行PostgreSQL——只要PostgreSQL的数据目录不是docker主机上的卷。

如果我试图运行它,将PostgreSQL的数据目录放在 named or bind volume ,PostgreSQL能够 初始数据库 但后来没能开始。

我怀疑错误是由于装入的卷在 symlink mcr.microsoft.com/windows/servercore:ltsc2016 ,导致PostgreSQL失败。打开 mcr.microsoft.com/windows/servercore:1809 ,此行为已更改装入的卷看起来像“普通”目录,PostgreSQL能够启动。

我正在使用的Dockerfile如下所示:

FROM mcr.microsoft.com/windows/servercore:ltsc2016
SHELL ["powershell", "-Command", "$ErrorActionPreference = 'Stop'; $ProgressPreference = 'SilentlyContinue';"]
ARG version=10.6-1

RUN MD data
RUN setx /M PGDATA "C:\data"

ENV PGUSER postgres
ENV PGPASSWORD postgres

COPY docker-entrypoint.cmd /
COPY start.cmd /

EXPOSE 5432

ENTRYPOINT ["docker-entrypoint.cmd"]
CMD [ "start.cmd"]

引用的 docker-entrypoint.cmd

@ECHO %PGPASSWORD% > pw.txt

@ECHO OFF
IF NOT EXIST %PGDATA%/PG_VERSION (
    initdb.exe --encoding=UTF8 --username=%PGUSER% --pwfile=pw.txt
    @echo host all all 0.0.0.0/0 trust > %PGDATA%/pg_hba.conf
    @echo host all all ::0/0 trust >> %PGDATA%/pg_hba.conf
)

%*

引用的 start.cmd 看起来像这样:

@echo off

pg_ctl start -o "-h * -c max_prepared_transactions=100 -c max_connections=1000"
