我正在运行一个项目，该项目使用 Docker 将 war 文件部署到 Wildfly 服务器。 我计划使用 Wildfly 27.0.1.Final 和 Postgres 9.4。
这是我的 docker-compose.yml 文件：
version: '2'
services:
database:
image: postgres:9.4
ports:
- "5433:5432"
environment:
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD=123456
- POSTGRES_DB=postgres
networks:
- resolute
wildfly:
depends_on:
- database
build:
context: .
dockerfile: Dockerfile
ports:
- "8080:8080"
- "9990:9990"
environment:
- DB_HOST=database
- DB_NAME=postgres
- DB_USER=postgres
- DB_PASS=123456
networks:
- resolute
command: /opt/jboss/wildfly/bin/standalone.sh -c standalone-full.xml -b 0.0.0.0 -bmanagement 0.0.0.0
networks:
resolute:
name: resolute
还有我的用于构建 Wildfly 容器的 Dockerfile：
FROM quay.io/wildfly/wildfly:27.0.1.Final-jdk17
COPY ./module.xml /opt/jboss/wildfly/modules/system/layers/base/org/eclipse/persistence/main
COPY ./eclipselink-4.0.0.jar /opt/jboss/wildfly/modules/system/layers/base/org/eclipse/persistence/main
COPY ./standalone-full.xml /opt/jboss/wildfly/standalone/configuration
ADD ./postgresql-42.6.0.jar /opt/jboss/wildfly/standalone/deployments/
ADD ./my-war-file.war .
RUN /opt/jboss/wildfly/bin/add-user.sh -u 'admin' -p 'admin'
我的数据源在standalone-full.xml中
<datasource jndi-name="java:/PostgresDS" pool-name="PostgresDS" enabled="true">
<connection-url>
jdbc:postgresql://host.docker.internal:5432/postgres
</connection-url>
<driver-class>
org.postgresql.Driver
</driver-class>
<datasource-class>
org.postgresql.ds.PGSimpleDataSource
</datasource-class>
<driver>
postgresql-42.6.0.jar
</driver>
<security>
<user-name>
postgres
</user-name>
<password>
123456
</password>
</security>
<validation>
<valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.postgres.PostgreSQLValidConnectionChecker" />
<background-validation>
true
</background-validation>
<exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.postgres.PostgreSQLExceptionSorter" />
</validation>
</datasource>
然后我运行
docker-compose up --build容器启动正常，postgres42.6.0部署成功。
然后我进入刚刚创建的 Wildfly 容器，将我的 war 文件复制到
/opt/jboss/wildfly/standalone/deployments/容器继续运行以部署我的 war 文件，但出现此错误。

我应该如何修复这个错误？非常感谢。
host.docker.internal ports:
- "5433:5432"
因此您需要将配置调整为如下所示：
<datasource jndi-name="java:/PostgresDS" pool-name="PostgresDS" enabled="true">
<connection-url>
jdbc:postgresql://host.docker.internal:5433/postgres
</connection-url>
但是没有理由在 docker-compose 堆栈中执行此操作。您可以直接引用其他容器和容器端口，如下所示：
<datasource jndi-name="java:/PostgresDS" pool-name="PostgresDS" enabled="true">
<connection-url>
jdbc:postgresql://database:5432/
</connection-url>
