Question

我正在学习Docker，这对我来说是全新的。我已经能够创建一个jboss / wildfly图像，然后我可以使用这个Dockerfile启动我的应用程序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

现在我想通过向独立和mysql连接器添加数据源来添加对MySQL数据库的支持。为此，我遵循这个例子：

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

以下是我的dockerfile和我的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

但是当我运行图像抱怨未找到文件或目录时出现错误：

构建图像

正在运行图片

$ docker run mpssantos/leadservice
no such file or directory
Error response from daemon: Cannot start container 5d3357ba17afa36e81d8794f2b0cd45cc00dde955b2b2054282c4ef17dd4f265: [8] System error: no such file or directory

有人可以让我知道如何访问文件系统，以便我可以检查哪个文件或目录正在抱怨？有没有更好的方法来调试它？

我认为这是与脚本的第一行引用的bash有关，因为未打印以下回声

非常感谢

我做了ssh容器来检查里面的内容。

1）ssh到docker机器：docker-machine ssh默认 2）使用以下命令检查容器ID：docker ps -a 3）用命令ssh到容器：sudo docker exec -i -t 665b4a1e17b6 / bin / bash 4）我可以检查“/ opt / jboss / wildfly / customization /”目录是否与预期文件一起存在

自定义目录具有以下权限，如下所示：

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

和自定义目录中的文件

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，我会收到此错误

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

这会给任何事情带来光明吗？

再次感谢你

Answer 1

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

Answer 2

我相信找不到execute.sh。您可以通过运行以下命令进行验证，并查找结果为空目录：

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

这样做的原因是你在不同的（虚拟）机器上进行构建，而不是本地系统，所以它正在推动自定义＆＃34;来自该VM的文件夹。我在VM中运行构建，并将要导入的文件放在构建可以找到它的VM上。
