Apache2 Image build using Dockerfile failed with http port as 8088

Hi,
I am trying to build the apache2 Image using Docker with http port as 8088. I submitted multiple times but still it says wrong. Can some one tell me what is wrong in the below Dockerfile?

FROM ubuntu:latest
RUN apt update
RUN apt install -y apache2
RUN apt install -y apache2-utils
EXPOSE :8088
CMD [“apache2ctl”, “-D”, “FOREGROUND”]

#2

EXPOSE does not change the apache port. That is always 80 unless you modify the configuration files of apache before starting it.

This has to be set in 2 places:

/etc/apache2/ports.conf

and

/etc/apache2/sites-enabled/000-default.conf

Since it’s an image build, you have to use sed to change these files

See here for what needs to be edited.

#3

Also there is no real need to make it serve on 8088 inside the container. Leave it as 80 and port map it

docker run -p 8088:80 your-image-name
