Docker 在wildlfy数据源定义（文件）中使用环境变量

我想将我的WAR应用程序重新打包为自我包含的docker映像-目前仍作为

WAR

部署到wildfly 19。 因为我不想让数据库密码和/或URL成为docker映像的一部分，所以我希望它可以从外部作为环境变量进行配置

因此，我当前的docker图像包括一个wildfly数据源定义，即

-ds.xml

文件，其中包含

env

占位符，因为根据

和其他来源，这应该是可能的

我的DS文件是

<datasources xmlns="http://www.jboss.org/ironjacamar/schema">
    <datasource jndi-name="java:jboss/datasources/dbtDS" pool-name="benchmarkDS">
        <driver>dbt-datasource.ear_com.mysql.jdbc.Driver_5_1</driver>
        <connection-url>${DB_CONNECTION_URL,env.DB_CONNECTION_URL}</connection-url>
        <security>
            <user-name>${DB_USERNAME,env.DB_USERNAME}</user-name>
            <password>${DB_PASSWORD,env.DB_PASSWORD}</password>
        </security>

        <pool>[...]</pool>
    </datasource>
</datasources>

最后一行说，

DS\u CONNECTION\u URL

似乎是空的-尝试了几种组合-相信我

Wrong driver class [com.mysql.jdbc.Driver] for this connection URL []

我要开始我的容器

docker run --name="dbt" --rm -it -p 8080:8080 -p 9990:9990     -e DB_CONNECTION_URL="jdbc:mysql://127.0.0.1:13306/dbt?serverTimezone=UTC"     -e DB_USERNAME="dbt"     -e DB_PASSWORD="_dbt" dbt

我甚至将

standalone.sh

修改为输出环境，并且

DB\u CONNECTION\u URL

就在那里

那么，启用wildfly替换DS文件中的占位符，我做错了什么呢？？ 它们似乎已被处理，因为它们的计算结果为空。但它们应该包含一些东西

如有任何建议，我们将不胜感激

我对自己做了回答-也许以后知道对别人有好处：

-ds.xml

文件中的占位符不受支持（！）

我通过使用

sed

进行修补，在

standalone.xml

中添加了相同的

datasource

定义，现在它可以正常工作，无需进一步修改
