I have a problem. My project is with the Laravel framework, and when I upload it to Docker, the size of the Docker image becomes 6 GB, which is too much. How can I reduce the size of the image?
This is my docker file:
FROM centos:7.7.1908

Changing the docker file to reduce its size
Decreasing the size of Docker Ver Laravel, can anyone help in this regard, how can I change the Docker file so that the size of the image is smaller, it is currently too large.
You have quite much going on in your image, so that's one thing. All the COPY and ADD instructions that I did not test amount to like 3GB already, when I comment them out (and a bunch of other stuff because the image does not build otherwise) I get around 4GB of image size.
Apart from those, a sureway to reduce the image size is to not do all of those yum installs separately.
Combine them and do a clean afterwards, like this:
RUN yum -y update && yum install -y \
epel-release \
unzip \
...
xorg-x11-fonts-75dpi \
crontabs \
cronie \
&& rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm \
&& yum -y clean all && rm -fr /var/cache
With that, I was able to reduce the image size from the 4GB (without ADD and COPY) to 600MB.
