Deploy Existing Drupal Website in Container Environment

1. Create web and DB images Seperately. So create seperate Dockerfiles for WEB and DB

FOR DB

1. Take DB backup and put it in same place with DB dokcerfile

FROM mariadb:latest as builder
# That file does the DB initialization but also runs mysql daemon, by removing the last line it will only init
RUN ["sed", "-i", "s/exec \"$@\"/echo \"not running $@\"/", "/usr/local/bin/docker-entrypoint.sh"]
# needed for intialization
ENV MYSQL_ROOT_PASSWORD=root
COPY *.sql  /docker-entrypoint-initdb.d/
# Need to change the datadir to something else that /var/lib/mysql because the parent docker file defines it as a volume.
# https://docs.docker.com/engine/reference/builder/#volume :
#       Changing the volume from within the Dockerfile: If any build steps change the data within the volume after
#       it has been declared, those changes will be discarded.
RUN ["/usr/local/bin/docker-entrypoint.sh", "mysqld", "--datadir", "/initialized-db", "--aria-log-dir-path", "/initialized-db"]
FROM mariadb:latest
COPY --from=builder /initialized-db /var/lib/mysql

FOR WEB

Dockerfile is as below

FROM php:7.3-apache-stretch
