Step 1) Create a Dockerfile
[root@stapp03 docker]# ls -rtl
total 12
drwxr-xr-x 2 root root 4096 Apr 11 02:53 html
drwxr-xr-x 2 root root 4096 Apr 11 02:53 certs
-rw-r--r-- 1 root root 518 Apr 11 02:53 Dockerfile
[root@stapp03 docker]# cat Dockerfile
FROM httpd:2.4.43
RUN sed -i "s/Listen 80/Listen 8080/g" /usr/local/apache2/conf/httpd.conf
RUN sed -i '/LoadModule\ ssl_module modules\/mod_ssl.so/s/^#//g' conf/httpd.conf
RUN sed -i '/LoadModule\ socache_shmcb_module modules\/mod_socache_shmcb.so/s/^#//g' conf/httpd.conf
RUN sed -i '/Include\ conf\/extra\/httpd-ssl.conf/s/^#//g' conf/httpd.conf
COPY certs/server.crt /usr/local/apache2/conf/server.crt
COPY certs/server.key /usr/local/apache2/conf/server.key
COPY html/index.html /usr/local/apache2/htdocs/
Step 2) Build the docker file.
[root@stapp03 docker]# docker build .
