Docker Jboss/wildfly：如何添加數據源和MySQL連接器

Question

我正在學習Docker，這對我來說是全新的。我已經能夠創建的JBoss/wildfly圖像，然後我能夠使用此Dockerfile我的應用程序啓動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 

現在我想通過添加一個數據源，以增加對MySQL數據庫支持獨立和mysql連接器。對於我下面這個例子：

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

以下是我dockerfile和我execute.sh腳本

Dockerfile：

FROM jboss/wildfly:latest 

ADD customization /opt/jboss/wildfly/customization/ 

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

執行腳本代碼：

#!/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 

但是當我運行投訴tha的圖像時出現錯誤TA的文件或目錄未找到：

建築形象

$ docker build -t mpssantos/leadservice:latest .

運行圖像

$ 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 

有人可以讓我知道我可以訪問文件系統，所以我可以檢查哪些文件或目錄抱怨？有沒有更好的方法來調試呢？

我相信那是後話與慶典有關這是因爲下面的回聲無法打印

謝謝你這麼多

我去到SSH方式對劇本的第一行稱容器來檢查裏面的東西。

1）的ssh到搬運工機：搬運工機的ssh默認 2）檢查與所述命令中的容器ID：搬運工PS -a 3）ssh來與該命令的容器：須藤搬運工EXEC -i -t 665b4a1e17b6 /斌/慶典 4）我可以檢查出「的/ opt/JBoss的/ wildfly /定製/」目錄與預期的文件

定製目錄具有下列權限，並列出這樣的存在：

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

和定製目錄內的文件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 

，如果我嘗試執行該文件我得到這個錯誤

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

這是否帶來光明什麼？

非常感謝你

Answer 1

我相信execute.sh找不到。您可以通過運行以下命令，查找結果確認是一個空目錄：

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

這樣做的原因是要在不同的（虛擬）機比在本地系統上做你的身材，所以它的拉「自定義「文件夾。我會在虛擬機中運行構建，並將想要導入的文件放置到構建可以找到它的虛擬機上。

Answer 2

我發現了這個問題。 execute.sh文件使用windows eof。我轉換到UNIX並開始工作。
