组合tomcat和postgres时，Docker镜像不运行

Question

我已经准备好了war文件和Dockerfile文件，现在我想创建一个环境，其中ubuntu:16.04作为容器操作系统，并安装java、tomcat、Postgres。镜像构建成功，但是当我运行容器时，我得到了一个错误

docker: Error response from daemon: OCI runtime create failed: container_linux.go:346: starting container process caused "exec: \"/usr/local/tomcat/bin/catalina.sh\": stat /usr/local/tomcat/bin/catalina.sh: permission denied": unknown.

我已经删除了postgres指令，然后tomcat运行得很好。

FROM ubuntu:16.04
#tomcat and java
RUN apt-get -y update && apt-get -y upgrade
RUN apt-get install nano
RUN apt-get -y install openjdk-8-jdk wget
RUN mkdir /usr/local/tomcat
RUN wget https://archive.apache.org/dist/tomcat/tomcat-9/v9.0.22/bin/apache-tomcat-9.0.22.tar.gz -O /tmp/tomcat.tar.gz
RUN cd /tmp && tar xvfz tomcat.tar.gz
RUN cp -Rv /tmp/apache-tomcat-9.0.22/ /usr/local/tomcat/
ADD tomcat-users.xml /usr/local/tomcat/conf/
ADD context.xml /usr/local/tomcat/webapps/host-manager/META-INF/

ADD myapp.war /usr/local/tomcat/webapps/

EXPOSE 8080
CMD ["/usr/local/tomcat/bin/catalina.sh", "run"]

#postgres
RUN apt-get -y update
RUN apt-get -y install wget
RUN apt-get -y update && apt-get -y upgrade
RUN echo "deb http://apt.postgresql.org/pub/repos/apt/ xenial-pgdg main" > /etc/apt/sources.list.d/pgdg.list


RUN wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | apt-key add -

RUN apt-get -y update
RUN apt-get install -y software-properties-common
RUN apt-get install -y postgresql-10
RUN apt-get install -y postgresql-client-10
RUN apt-get install -y postgresql-contrib-10

USER postgres
RUN /etc/init.d/postgresql start &&\
    psql --command "CREATE USER postgresondocker WITH SUPERUSER PASSWORD 'postgresondocker';" &&\
    createdb -O postgresondocker postgresondocker
RUN echo "host all  all    0.0.0.0/0  md5" >> /etc/postgresql/10/main/pg_hba.conf
RUN echo "listen_addresses='*'" >> /etc/postgresql/10/main/postgresql.conf
EXPOSE 5432
VOLUME  ["/etc/postgresql", "/var/log/postgresql", "/var/lib/postgresql"]

# Set the default command to run when starting the container
#CMD ["/usr/lib/postgresql/10/bin/postgres", "-D", "/var/lib/postgresql/10/main", "-c", "config_file=/etc/postgresql/10/main/postgresql.conf"]

如果我以#postgres开头注释postgres安装，那么tomcat运行得很好。另外，postgres的#CMD不同于tomcat，我读到我不能使用两个CMD指令，因为最后一个将被执行。如何将tomcat和postgres的CMD指令结合起来？

试试这个也许行得通。编辑合成文件，如下所示：

.
.
.
EXPOSE 8080
RUN chmod +x /usr/local/tomcat/bin/catalina.sh
CMD ["/usr/local/tomcat/bin/catalina.sh", "run"]
.
