How to deploy web service on Docker container
This is my Dockerfile:
#Build java web app container image FROM ubuntu MAINTAINER wangyao #Make java and tomcat install directory RUN mkdir /usr/local/java RUN mkdir /usr/local/tomcat #Copy jre and tomcat into image ADD jdk1.8.0_45.jdk /usr/local/java/ ADD apache-tomcat-7.0.62 /usr/local/tomcat/ ENV JAVA_HOME=/usr/local/java/Contents/Home CMD cd /usr/local/tomcat;./bin/catalina.sh run #Expose http port EXPOSE 8080
Then i built it and try to start it:
wangyaos-MBP-3:flexcloud wangyao$ ls Dockerfile apache-tomcat-7.0.62 jdk1.8.0_45.jdk wangyaos-MBP-3:flexcloud wangyao$ docker build -t flexcloud .

word unexpected (expecting ")") mean ?
$ ./bin/catalina.sh run without docker, and I can run it, but i why can not run it on the docker container ?

As indicated in the comments, the error
Syntax error: word unexpected (expecting ")") is a shell script error, which implies that
/usr/local/java/Contents/Home/bin/java is not actually the java executable.
Accessing the container with
docker exec -it <container> bash and executing
/usr/local/java/Contents/Home/bin/java -version shows us whats actually going on, as per @KingOfSocket’s comment.
