Unable to open application after docker-compose

Question

After composing docker file, everything builds fine but after doing docker ps it shows no containers are running.

Below is my docker-compose.yml

version: '3'
services:
  web-app:
    build:
      context: .
      dockerfile: web-app/Dockerfile
    ports:
      - 8080:8080
    links:
      - app-db

  app-db:
    build:
      context: .
      dockerfile: app-db/Dockerfile

    environment:
    - MYSQL_ROOT_PASSWORD=password
    - MYSQL_DATABASE=Optimize
    ports:
      - 3306:3306

and Dockerfile for web-app is like

FROM aallam/oracle-java
    
ENV DEBIAN_FRONTEND noninteractive
ENV TOMCAT_MAJOR_VERSION=8
ENV TOMCAT_VERSION=8.5.14
ENV TOMCAT_HOME=/opt/tomcat

RUN apt-get update && \
  rm -rf /var/lib/apt/lists/*

WORKDIR /tmp

RUN groupadd tomcat && \
    useradd -s /bin/false -g tomcat -d $TOMCAT_HOME tomcat && \
    mkdir $TOMCAT_HOME && \
    #wget http://mirrors.standaloneinstaller.com/apache/tomcat/tomcat-$TOMCAT_MAJOR_VERSION/v$TOMCAT_VERSION/bin/apache-tomcat-$TOMCAT_VERSION.tar.gz && \
    wget http://archive.apache.org/dist/tomcat/tomcat-8/v8.0.23/bin/apache-tomcat-8.0.23.tar.gz && \
    tar xzvf apache-tomcat-8*tar.gz -C $TOMCAT_HOME --strip-components=1 && \
    chown -R tomcat:tomcat $TOMCAT_HOME && \
    chmod -R g+r $TOMCAT_HOME/conf && \
    chmod g+x $TOMCAT_HOME/conf && \
    rm -rf apache-tomcat-$TOMCAT_VERSION.tar.gz

WORKDIR /

RUN chmod 755 /*.sh

COPY /web-app/target/*.war $TOMCAT_HOME/webapps/

expose 8080
ENTRYPOINT ["/run.sh"]

and the Dockerfile for database for is like

FROM aallam/oracle-java
ENV DEBIAN_FRONTEND noninteractive
RUN apt-get update && \
  apt-get -yq install mysql-server supervisor && \
  rm -rf /var/lib/apt/lists/*

#WORKDIR /
ADD /app-db/bind_0.cnf /etc/mysql/conf.d/bind_0.cnf
ADD /app-db/mysql-run.sh /mysql-run.sh
ADD /app-db/supervisord-mysql.conf /etc/supervisor/conf.d/supervisord-mysql.conf

VOLUME ["/var/lib/mysql"]
expose 3306

after docker-compose up -d this was the output in the terminal

user@ubuntu:~/Creating optdocker_app-db_1

user@ubuntu:~/Creating optdocker_web-app_1

adding docker-compose logs and netstat -tln

What does `run.sh` do? Can you provide the contents of the script? — Raktotpal Bordoloi, Jun 14 '17 at 07:29
looks like your entrypoint is wrong. have you tried to run them standalone and watch what the console output is? if it gives you exited by 0, your entrypoint stoped because the task finished and the container stops working. — Gabbax0r, Jun 14 '17 at 08:01
@Gabbax0r yup.... entry point is not working after running the `Dockerfile` of web app. Can you please help me with this — Prateek Naik, Jun 14 '17 at 08:32
try just ENTRYPOINT ["/bin/bash"]. if its run you can skript the programm start on your own — Gabbax0r, Jun 14 '17 at 08:45

Update Dockerfile in web-app like this:

FROM aallam/oracle-java

ENV DEBIAN_FRONTEND noninteractive
ENV TOMCAT_MAJOR_VERSION=8
ENV TOMCAT_VERSION=8.5.14
ENV TOMCAT_HOME=/opt/tomcat

RUN apt-get update && \
apt-get -yq install supervisor && \
  rm -rf /var/lib/apt/lists/*

WORKDIR /tmp

RUN groupadd tomcat && \
    useradd -s /bin/false -g tomcat -d $TOMCAT_HOME tomcat && \
    mkdir $TOMCAT_HOME && \
    #wget http://mirrors.standaloneinstaller.com/apache/tomcat/tomcat-$TOMCAT_MAJOR_VERSION/v$TOMCAT_VERSION/bin/apache-tomcat-$TOMCAT_VERSION.tar.gz && \
    wget http://archive.apache.org/dist/tomcat/tomcat-8/v8.0.23/bin/apache-tomcat-8.0.23.tar.gz && \
    tar xzvf apache-tomcat-8*tar.gz -C $TOMCAT_HOME --strip-components=1 && \
    chown -R tomcat:tomcat $TOMCAT_HOME && \
    chmod -R g+r $TOMCAT_HOME/conf && \
    chmod g+x $TOMCAT_HOME/conf && \
    rm -rf apache-tomcat-$TOMCAT_VERSION.tar.gz

WORKDIR /

ADD /web-app/tomcat-run.sh /tomcat-run.sh
ADD /web-app/run.sh /run.sh
ADD /web-app/supervisord-tomcat.conf /etc/supervisor/conf.d/supervisord-tomcat.conf
ADD /web-app/settings.xml $TOMCAT_HOME/conf/settings.xml
ADD /web-app/tomcat-users.xml $TOMCAT_HOME/conf/tomcat-users.xml
ADD /web-app/context.xml $TOMCAT_HOME/webapps/manager/META-INF/context.xml
RUN chmod 755 /*.sh

COPY /web-app/target/*.war $TOMCAT_HOME/webapps/

expose 8080
ENTRYPOINT ["/run.sh"]

Duplicate run.sh for both web-app and app-db folder.

Update Dockerfile in app-db like this:

FROM aallam/oracle-java
ENV DEBIAN_FRONTEND noninteractive
RUN apt-get update && \
  apt-get -yq install mysql-server supervisor && \
  rm -rf /var/lib/apt/lists/*

#WORKDIR /
ADD /app-db/run.sh /run.sh
ADD /app-db/bind_0.cnf /etc/mysql/conf.d/bind_0.cnf
ADD /app-db/mysql-run.sh /mysql-run.sh
ADD /app-db/supervisord-mysql.conf /etc/supervisor/conf.d/supervisord-mysql.conf

VOLUME ["/var/lib/mysql"]
expose 3306
ENTRYPOINT ["/run.sh"]

Then run commands:

docker-compose up
docker ps

Output will be like this and system is up:

CONTAINER ID        IMAGE               COMMAND             CREATED                  STATUS              PORTS                    NAMES
a60682b914a4        test_web-app        "/run.sh"           Less than a second ago   Up 9 seconds        0.0.0.0:8080->8080/tcp   test_web-app_1
607522cac623        test_app-db         "/run.sh"           Less than a second ago   Up 9 seconds        0.0.0.0:3306->3306/tcp   test_app-db_1

To connect MySQL server in app-db container, your JDBC connection url in your project should be something like this:

"jdbc:mysql://DOCKER_MACHINE_IP:3306/DB_NAME".

At the app-db container side, access MySQL from command line, create and give permissions for user with DOCKER_MACHINE_IP:

> CREATE USER 'root'@'DOCKER_MACHINE_IP' IDENTIFIED BY 'root_password'; 
> GRANT ALL ON *.* to root@'DOCKER_MACHINE_IP' IDENTIFIED BY 'root_password';
> FLUSH PRIVILEGES;

The containers are up but i guess its not connecting with the MySQL [here are the logs](https://gist.github.com/Beanben/eb28d3084b9caf899728842d8c8980b5) can anyone help me — Prateek Naik, Jun 14 '17 at 16:35
It seems project under target folder can't start before connecting database. Can you add catalina and localhost full logs? Also please check whether mysql has the database you want to create. — javasenior, Jun 15 '17 at 07:45
Yup there is no database which i wanted to create and also please find the [logs here](https://gist.github.com/Beanben/d0b81b87ef787409e613223318eb86ac) — Prateek Naik, Jun 15 '17 at 10:23
Deploying process look like healthy. SEVERE logs are related with https://stackoverflow.com/questions/24850091 and https://stackoverflow.com/questions/3320400. — javasenior, Jun 15 '17 at 11:27
after implementing your solution getting this error `ERROR: for app-db Cannot start service app-db: oci runtime error: container_linux.go:247: starting container process caused "exec: \"/run.sh\": permission denied"` — Prateek Naik, Jun 15 '17 at 12:04
