如何在Dockerfile中启动容器时运行jboss-cli

Question

我正在尝试使用Dockerfile创建一个图像Docker容器。当Docker容器启动时，我需要使用jboss-cli执行一些命令。要执行jboss-cli，需要运行wildfly服务。

我的Dockerfile：

FROM jboss/wildfly:latest

USER jboss

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

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

我尝试在我的Dockerfile中添加一个jboss-cli命令。

FROM jboss/wildfly:latest

USER jboss

COPY mysql-connector-java-5.1.44.jar /opt/jboss/

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

USER root
#in this line is needed to change owner file to jboss user use this file
RUN chown jboss.root /opt/jboss/mysql-connector-java-5.1.44.jar
USER jboss

CMD ["/opt/jboss/wildfly/bin/standalone.sh", "-b", "0.0.0.0", "-bmanagement", "0.0.0.0"]
CMD ["/opt/jboss/wildfly/bin/jboss-cli.sh", "-c", "controller=localhost:9990", "--user=admin", "--password=admin", "--command=\"module add --name=com.mysql --resources=/opt/jboss/mysql-connector-java-5.1.44.jar --dependencies=javax.api,javax.transaction.api\""]

当我运行docker run命令时：

docker run --name=wildfly-ci -p 8080:8080 -p 9990:9990 wildfly-ci

我在运行Docker命令时，从JBoss-cli收到了这个错误消息。

Failed to connect to the controller: The controller is not available at localhost:9990: java.net.ConnectException: WFLYPRT0053: Could not connect to remote+http://localhost:9990. The connection failed: WFLYPRT0053: Could not connect to remote+http://localhost:9990. The connection failed: XNIO000812: Connection closed unexpectedly

我不知道是因为此时wildfly的服务尚未运行，还是与Docker容器有关的某些行为。

当我运行docker exec CONTAINER_ID jboss-cli命令时，命令成功运行。 - Welton Leão Machado

@ОлегГаврилів 不是的，我写了一个 sh (Linux) 和 cmd (Windows) 脚本来运行它。 - Welton Leão Machado

@WeltonLeãoMachado，能给我展示一下脚本吗？ - Олег Гаврилів

从 docker 文档 中得知：一个 Dockerfile 中只能有一个 CMD 指令。如果你列出多个 CMD，则只有最后一个 CMD 会生效。 - ChristophS

这对我有效：

   RUN /bin/sh -c '$JBOSS_HOME/bin/standalone.sh -c=standalone-full.xml &' && \
      sleep 10 && \
      cd /tmp && \
      $JBOSS_HOME/bin/jboss-cli.sh --connect --command="module add --name=org.postgresql --resources=$JBOSS_HOME/standalone/configuration/postgresql-42.2.5.jar --dependencies=javax.api,javax.transaction.api,javax.servlet.api" && \
      $JBOSS_HOME/bin/jboss-cli.sh --connect --command=:shutdown 


    # User root to modify war owners
    USER root

    CMD ["/opt/eap/bin/standalone.sh", "-c", "standalone-full.xml", "-b", "0.0.0.0","-bmanagement","0.0.0.0"]

尝试使用单个CMD的Dockerfile：

Dockerfile FROM jboss/wildfly:latest USER jboss COPY mysql-connector-java-5.1.44.jar /opt/jboss/ RUN /opt/jboss/wildfly/bin/add-user.sh admin admin --silent USER root RUN chown jboss.root /opt/jboss/mysql-connector-java-5.1.44.jar USER jboss CMD ["/opt/jboss/wildfly/bin/standalone.sh", "-b", "0.0.0.0", "-bmanagement", "0.0.0.0",";","/opt/jboss/wildfly/bin/jboss-cli.sh", "-c", "controller=localhost:9990", "--user=admin", "--password=admin", "--command=\"module add --name=com.mysql --resources=/opt/jboss/mysql-connector-java-5.1.44.jar --dependencies=javax.api,javax.transaction.api\""]

针对您所要做的事情，使用Docker来对XML文件应用补丁可能会更简单，而不是尝试使用jboss-cli。 - Will Tatam
