docker file tomcat configuration with docker file

Question

i want to create a docker file with tomcat server . i have two war files war 1 and war 2. i copied war1.xml into /usr/local/tomcat/conf/Catalina/localhost/ i copied war2.xml into /usr/local/tomcat/conf/Catalina/localhost/

here is the context of war1.xml

<Resources>
    <Resource
            name="jdbc/app1"
            type="javax.sql.DataSource"
            auth="Container"
            username="root"
            password="toto"
            driverClassName="com.mysql.jdbc.Driver"
            url="jdbc:mysql://localhost:3306">
    </Resource>
    <PreResources className="org.apache.catalina.webresources.DirResourceSet" base="/app/ml/ts/config/"
                  webAppMount="/WEB-INF/classes"/>

    <ResourceLink global="app1" name="app1" type="javax.sql.DataSource"/>
</Resources>

here are my docker files :

FROM tomcat:8.0-jre8-alpine

COPY app1/target/war1.war /usr/local/tomcat/webapps/
COPY app2/target/app2.war /usr/local/tomcat/webapps/


COPY app1/src/main/resources/conf/app1.xml /usr/local/tomcat/conf/Catalina/localhost/
COPY app2/src/main/resources/app2/conf/app2.xml /usr/local/tomcat/conf/Catalina/localhost/

COPY app1/src/main/resources/app1/scripts/* 

EXPOSE 8080

CMD ["catalina.sh","run"]

here is mysql docker file :

    FROM mysql:5.7
    
    # Add a database
    ENV MYSQL_DATABASE MyDb
    
    ENV MYSQL_ROOT_PASSWORD toto
    
    # Add the content of the sql-scripts/ directory to your image
    # All scripts in docker-entrypoint-initdb.d/ are automatically
    # executed during container startup
    COPY app-livraison/src/main/resources/db/ /docker-entrypoint-initdb.d/

here is my docker compose file :

    version: '3'
services:
  tomcat:
    build:
      context: .
      dockerfile: Dockerfile.tomcat
    ports:
      - 8080:8080
  mysql:
    build:
      context: .
      dockerfile: Dockerfile.db
    environment:
      MYSQL_ROOT_PASSWORD: toto
      MYSQL_DATABASE: Mydb

but the context could not add the datasource , i have the following error :

BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.jdbc.datasource.lookup.DataSourceLookupFailureException: Failed to look up JNDI DataSource with name '"glc-batch"'; nested exception is javax.naming.NameNotFoundException: Name [app1] is not bound in this Context.

Answer 1

the problem was the JNDI-NAME , in the properties file you should give the complete name defined in server.xml : jndi/datasourceName without quotation marks. that was not a docker problem. thanks
