如何使用Dockerfile在启动docker容器上运行jboss-cli

Question

我正在尝试用Dockerfile创建镜像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，必须运行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

运行docker命令时，收到来自jboss-cli的此消息错误

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wildfly的服务目前还没有运行，还是因为Docker Container的一些行为。

Answer 1

这对我来说很有效：

   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"]

使用单个CMD试用此Dockerfile，

Dockerfile

来自jboss/wildfly:最新

用户jboss

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

运行/opt/jboss/wildfly/bin/add-user.sh admin admin --静默

root用户运行chown jboss.root /opt/ jboss /mysql-connector-java-5.1.44.jar用户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"，“--用户=管理员”，“--密码=管理员”，“--命令=\”模块添加--名称=com.mysql --resources=/opt/jboss/mysql-connector-java-5.1.44.jar --依赖关系=javax.api，javax.transaction.api\"“
