How to send user input as some text inside Dockerfile?

I have following Dockerfile:

FROM ubuntu RUN apt-get -y update RUN apt-get -y install ttf-dejavu COPY ./soap.sh / RUN chmod +x /soap.sh ENTRYPOINT ["/soap.sh"] CMD ["/script.sh", "arg1"] 

I am trying to install SoapUI using above Dockerfile.

Using above Dockerfile, I am able to build the image Successfully as shown below:

root@test00-new:/home/sam/1_Docker# docker build -t balu1 . Sending build context to Docker daemon 385.8MB Step 1/8 : FROM ubuntu ---> 1e4467b07108 Step 2/8 : MAINTAINER Sample ---> Running in c6dc0992d25c Removing intermediate container c6dc0992d25c ---> 7ecd8a4fcbfd Step 3/8 : RUN apt-get -y update ---> Running in aa6467b0fc5c ---> cd3b7f8f5389 Step 4/8 : RUN apt-get -y install ttf-dejavu ---> Running in 8fcc7ce6ab9f ---> 55649115b86c Step 5/8 : COPY ./soap.sh / ---> 2c236754e2d5 Step 6/8 : RUN chmod +x /soap.sh ---> Running in 408d72761df5 Removing intermediate container 408d72761df5 ---> 17d2afb0bc43 Step 7/8 : ENTRYPOINT ["/soap.sh"] ---> Running in 0b10d8b91d65 Removing intermediate container 0b10d8b91d65 ---> a7d0b50d4fdd Step 8/8 : CMD ["/script.sh", "arg1"] ---> Running in a8ba5d134b5d Removing intermediate container a8ba5d134b5d ---> d41cffedccda Successfully built d41cffedccda Successfully tagged balu1:latest root@test00-new:/home/sam/1_Docker# docker images REPOSITORY TAG IMAGE ID CREATED SIZE balu1 latest d41cffedccda 29 seconds ago 351MB ubuntu latest 1e4467b07108 3 weeks ago 73.9MB root@test00-new:/home/sam/1_Docker# 

But When I run the docker using above image, I am getting the following output:

root@test00-new:/home/sam/1_Docker# docker run balu1 OK Unpacking JRE ... Preparing JRE ... Starting Installer ... This will install SoapUI 5.2.1 on your computer. OK [o, Enter], Cancel [c] root@test00-new:/home/sam/1_Docker# 

In the above case how to handle user input in Dockerfile?

I need to send a letter o or ENTER as input inside Dockerfile

I tried by running "docker run balu1 0", "docker run balu1 OK" etc. But its not working.

Please guide me on this.
