docker-compose build fail with file not found - docker

Question

I would like to ask a question regarding the docker-compose.yml and Dockerfile.
Following is the situation I have met.
I first use docker image build (docker image build -t test .) and docker run (docker run -p 8888:8080 -p 8889:8009 8883:8443 -v tomcat8:/usr/local/tomcat8 --name test test) to test whether my Dockerfile is ready to go, and it is working.
Dockerfile
FROM ubuntu:latest
ENV HOME /usr/local/tomcat8
RUN apt-get -y update && apt-get -y install unzip wget openjdk-8-jdk
COPY ./installERDDAP.sh $HOME/installERDDAP.sh
COPY . $HOME/
RUN chmod +x $HOME/installERDDAP.sh
WORKDIR $HOME
RUN ./installERDDAP.sh
EXPOSE 8080 8443 8009
CMD ["catalina.sh","run"]
So that I script the docker-compose.yml, like below
docker-compose.yml
version: '3'
services:
erddap:
build:
context: ./
dockerfile: Dockerfile
image: erddap_dev:2.02
container_name: erddap
restart: always
ports:
- "8888:8080"
- "8883:8443"
- "8889:8009"
volumes:
- ./tomcat8:/usr/local/tomcat8
However, the error message popup and said that the file catalina.sh does not exist. When I get into the container, well, that is true. There are no files existed. But if I put RUN ls -la in the Dockerfile, I do see the files are listed, like below.
Step 12/14 : RUN ls -la

Removing intermediate container fed4870bd617
Interestingly, these files are not also showing up in my volume directory. Could please someone tells me where am I wrong?
Thanks
1st Updates:
According to the suggestion below, if I commended out the volumes within docker-compose.yml or if I added WORKDIR / in front of the CMD command, none of them are working.
If I modified CMD commend in Dockfile from CMD ["catalina.sh","run"] to CMD ["./catalina.sh","run"] is not working, too. But if I changed to CMD ["/usr/local/tomcat8/catalina.sh","run"], the build process is completed. But the errors than become

Answer 1

From what I can tell your bind mount may be "overriding/hiding" your container files. If your "./tomcat8" directory is not empty it will basically "override/hide" the files in your container. I would remove the volume declaration to validate if this is the case, if so then you would need to clear out your "./tomcat8" directory and when you run the container again it should populate it with the files in the container, from then forward your local directory will again "override/hide" your container files.

Answer 2

In your docker file before the line CMD ["catalina.sh","run"] put WORKDIR / And change "catalina.sh" to "./catalina.sh"
