Wildfly Java 应用程序的 Dockerfile

Question

我正在尝试为我的 Wildfly Java 应用程序 创建一个 docker 映像。我的应用程序使用 JNDI 创建了一个与 DataSource 的 mysql 连接。我的 ORM 是 休眠。当我跑步时

docker build -t mytag-app .

返回错误：

The command is not available in the current context (e.g. required subsystems or connection to the controller might be unavailable).
The command '/bin/sh -c /opt/jboss/wildfly/bin/jboss-cli.sh --user=admin --password=admin --commands="data-source add --name=source1 --jndi-name=java:jboss/datasources/MySqlDS --driver-name=mysql-connector-java-8.0.11.jar  --connection-url=jdbc:mysql://sihors.com:3306/nynnphsj_wifigate2?serverTimezone=UTC --user-name=nynnphsj_loretto25 --password=dsotmpinkflo --enable=true"' returned a non-zero code: 1

我确定我的 Dockerfile 错了，但是在哪里？

我运行 docker 的文件夹有：

• restful.war
• mysql-connector-java-8.0.12.jar
• Dockerfile

这是我的 Dockerfile：

FROM jboss/wildfly

RUN /opt/jboss/wildfly/bin/add-user.sh admin admin --silent

ADD restful.war /opt/jboss/wildfly/standalone/deployments/
ADD mysql-connector-java-8.0.12.jar /opt/jboss/wildfly/standalone/deployments/

RUN /opt/jboss/wildfly/bin/jboss-cli.sh --user=admin --password=admin --commands="data-source add --name=source1 --jndi-name=java:jboss/datasources/MySqlDS --driver-name=mysql-connector-java-8.0.11.jar  --connection-url=jdbc:mysql://mydomain.com:3306/mydb2?serverTimezone=UTC --user-name=root --password=root --enable=true"

EXPOSE 8080 9990

CMD ["/opt/jboss/wildfly/bin/standalone.sh", "-b", "0.0.0.0", "-bmanagement", "0.0.0.0"]

这是我用于 java 应用程序的 Pom.xml：

如何通过mysql数据源连接为wildfly java app创建docker镜像？

Answer 1

docker build 是关于基于 Dockerfile 构建容器镜像。此时你的容器没有运行，你的wildfly也没有。你的 jboss-cli.sh 不能工作，因为这是关于与 running wildfly 交互的。

要实现您的目标，您有两个选择

• ADD 配置了数据源的容器中的配置文件（最有可能是standalone.xml）。每当容器基于您的图像启动时，wildfly 都会读取并连接。

• ADD自制的entrypoint.sh；一个 bash 脚本，它将启动 wildfly 并运行您需要配置您的 widlfy 的任何内容。
