Docker Jboss/wildfly：如何添加数据源和MySQL连接器

Question

我正在学习Docker，这对我来说是全新的。我已经能够创建的JBoss/wildfly图像，然后我能够使用此Dockerfile我的应用程序启动JBoss：

FROM jboss/wildfly 

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

ADD mywebapp-web/target/mywebapp-1.0.war /opt/jboss/wildfly/standalone/deployments/mywebapp-1.0.war 

现在我想通过添加一个数据源，以增加对MySQL数据库支持独立和mysql连接器。对于我下面这个例子：

https://github.com/arun-gupta/docker-images/tree/master/wildfly-mysql-javaee7

以下是我dockerfile和我execute.sh脚本

Dockerfile：

FROM jboss/wildfly:latest 

ADD customization /opt/jboss/wildfly/customization/ 

CMD ["/opt/jboss/wildfly/customization/execute.sh"] 

执行脚本代码：

#!/bin/bash 

# Usage: execute.sh [WildFly mode] [configuration file] 
# 
# The default mode is 'standalone' and default configuration is based on the 
# mode. It can be 'standalone.xml' or 'domain.xml'. 

echo "=> Executing Customization script" 

JBOSS_HOME=/opt/jboss/wildfly 
JBOSS_CLI=$JBOSS_HOME/bin/jboss-cli.sh 
JBOSS_MODE=${1:-"standalone"} 
JBOSS_CONFIG=${2:-"$JBOSS_MODE.xml"} 

function wait_for_server() { 
    until `$JBOSS_CLI -c ":read-attribute(name=server-state)" 2> /dev/null | grep -q running`; do 
    sleep 1 
    done 
} 

echo "=> Starting WildFly server" 

echo "JBOSS_HOME : " $JBOSS_HOME 
echo "JBOSS_CLI : " $JBOSS_CLI 
echo "JBOSS_MODE : " $JBOSS_MODE 
echo "JBOSS_CONFIG: " $JBOSS_CONFIG 

echo $JBOSS_HOME/bin/$JBOSS_MODE.sh -b 0.0.0.0 -c $JBOSS_CONFIG & 
$JBOSS_HOME/bin/$JBOSS_MODE.sh -b 0.0.0.0 -c $JBOSS_CONFIG & 

echo "=> Waiting for the server to boot" 
wait_for_server 

echo "=> Executing the commands" 
$JBOSS_CLI -c --file=`dirname "$0"`/commands.cli 

# Add MySQL module 
module add --name=com.mysql --resources=/opt/jboss/wildfly/customization/mysql-connector-java-5.1.39-bin.jar --dependencies=javax.api,javax.transaction.api 

# Add MySQL driver 
/subsystem=datasources/jdbc-driver=mysql:add(driver-name=mysql,driver-module-name=com.mysql,driver-xa-datasource-class-name=com.mysql.jdbc.jdbc2.optional.MysqlXADataSource) 

# Deploy the WAR 
#cp /opt/jboss/wildfly/customization/leadservice-1.0.war $JBOSS_HOME/$JBOSS_MODE/deployments/leadservice-1.0.war 

echo "=> Shutting down WildFly" 
if [ "$JBOSS_MODE" = "standalone" ]; then 
    $JBOSS_CLI -c ":shutdown" 
else 
    $JBOSS_CLI -c "/host=*:shutdown" 
fi 

echo "=> Restarting WildFly" 
$JBOSS_HOME/bin/$JBOSS_MODE.sh -b 0.0.0.0 -c $JBOSS_CONFIG 

但是当我运行投诉tha的图像时出现错误TA的文件或目录未找到：

建筑形象

$ docker build -t mpssantos/leadservice:latest .

运行图像

$ docker run mpssantos/leadservice 
no such file or directory

有人可以让我知道我可以访问文件系统，所以我可以检查哪些文件或目录抱怨？有没有更好的方法来调试呢？

我相信那是后话与庆典有关这是因为下面的回声无法打印

谢谢你这么多

我去到SSH方式对剧本的第一行称容器来检查里面的东西。

1）的ssh到搬运工机：搬运工机的ssh默认 2）检查与所述命令中的容器ID：搬运工PS -a 3）ssh来与该命令的容器：须藤搬运工EXEC -i -t 665b4a1e17b6 /斌/庆典 4）我可以检查出“的/ opt/JBoss的/ wildfly /定制/”目录与预期的文件

定制目录具有下列权限，并列出这样的存在：

drwxr-xr-x 2 root root 4096 Jun 12 23:44 customization 
drwxr-xr-x 10 jboss jboss 4096 Jun 14 00:15 standalone 

和定制目录内的文件dir

drwxr-xr-x 2 root root 4096 Jun 12 23:44 . 
drwxr-xr-x 12 jboss jboss 4096 Jun 14 00:15 .. 
-rwxr-xr-x 1 root root 1755 Jun 12 20:06 execute.sh 
-rwxr-xr-x 1 root root 989497 May 4 11:11 mysql-connector-java-5.1.39-bin.jar 

，如果我尝试执行该文件我得到这个错误

[jboss@d68190e4f0d8 customization]$ ./execute.sh 
bash: ./execute.sh: /bin/bash^M: bad interpreter: No such file or directory 

这是否带来光明什么？

非常感谢你

Answer 1

我相信execute.sh找不到。您可以通过运行以下命令，查找结果确认是一个空目录：

docker run mpssantos/leadservice ls -al /opt/jboss/wildfly/customization/ 

这样做的原因是要在不同的（虚拟）机比在本地系统上做你的身材，所以它的拉“自定义“文件夹。我会在虚拟机中运行构建，并将想要导入的文件放置到构建可以找到它的虚拟机上。

Answer 2

我发现了这个问题。 execute.sh文件使用windows eof。我转换到UNIX并开始工作。
