I would like to add my mysql database to my Dockefile running ubuntu with installed mysql and php. The folder is structured in this way:
folder
|_ Dockerfile
|_ start.sh
|_ index.php
|_ init.sql
the problem is that start.sh don't exec all of my code, so the init.sql is not imported in mysql. I have looked some solution on StackOverflow but no one of them worked.
this is the Dockerfile
FROM ubuntu:latest
RUN apt-get update && apt-get upgrade -y
RUN DEBIAN_FRONTEND=noninteractive apt-get install apache2 php libapache2-mod-php php-mysql mysql-server -y
VOLUME ["/var/lib/mysql"]
ADD init.sql /tmp/init.sql
COPY index.php /var/www/html/
COPY start.sh /bin/
RUN chmod +x /bin/start.sh
EXPOSE 80 3306
CMD "/bin/start.sh"
This is the start.sh
#!/bin/bash
/usr/sbin/apache2ctl -D FOREGROUND
/usr/bin/mysqld_safe
mysql -u root -e "CREATE DATABASE mydb"
mysql -u root mydb < /tmp/init.sql
I'm not sure the problem is exactly start.sh, anyway every docker-compose solution will be useless for me since i need everything in a Dockerfile
first you must reorder sequence in you start.sh , because apache in foreground will prevent you to run mysql .
#!/bin/bash
chown -R mysql:mysql /var/lib/mysql /var/run/mysqld && /etc/init.d/mysql start
while [ ! -e /var/run/mysqld/mysqld.sock ]
do
sleep 2
done
mysqladmin ping
mysql -u root -e "CREATE DATABASE mydb"
mysql -u root mydb < /tmp/init.sql
/usr/sbin/apache2ctl -D FOREGROUND
and you must modify your Dockerfile to add :
RUN mkdir /var/run/mysqld ; chown mysql.mysql /var/run/mysqld

I have a simple docker stack with three containers : a mysql one, a php-fpm one and a nginx.
I just want to be able to execute my doctrine migrations and a symfony command every time my container is created.
Currently, i got an error like : "entrypoint.sh not found" when i type docker logs #myphpcontainername# after building and docker-compose up -d 'ing.
My php-fpm docker file :
FROM php:7.2-fpm
RUN apt-get update
RUN apt-get install -y zlib1g-dev libpq-dev git libicu-dev libxml2-dev \
......
RUN curl --insecure https://getcomposer.org/composer.phar -o /usr/bin/composer && chmod +x /usr/bin/composer
WORKDIR /var/www/symfony
COPY entrypoint.sh /entrypoint.sh
ENTRYPOINT ['/entrypoint.sh']
And my entrypoint.sh, located at the same place than my Dockerfile :
#!/bin/bash
set -e
sleep 5
php /var/www/symfony/bin/console doctrine:migrations:migrate --no-interaction --allow-no-migration
exec "$#"
I believe you will need to make that file executable
RUN chmod 0700 entrypoint.sh
or it should be
ENTRYPOINT /entrypoint.sh
Take a look at this post that has a good explanation
https://www.ctl.io/developers/blog/post/dockerfile-entrypoint-vs-cmd/
Try this
ADD . /var/www/symfony
WORKDIR /var/www/symfony
RUN chmod +x entrypoint.sh
...
CMD ["/var/www/symfony/entrypoint.sh"]
I have this multi-stage build in a Dockerfile:
## Stage 1
FROM node:9 as builder
RUN apt-get update && apt-get -y install sudo
RUN echo "newuser ALL=(ALL) NOPASSWD:ALL" >> /etc/sudoers
RUN useradd -ms /bin/bash newuser
USER newuser
RUN mkdir -p /home/newuser/app
WORKDIR /home/newuser/app
RUN sudo chown -R $(whoami) $(npm config get prefix)/lib
RUN npm set progress=false
RUN npm config set depth 0
RUN npm cache clean --force
COPY dist .
## Stage 2
FROM php:5.6.30
RUN apt-get update && apt-get -y install sudo
RUN echo "newuser ALL=(ALL) NOPASSWD:ALL" >> /etc/sudoers
RUN useradd -ms /bin/bash newuser
USER newuser
RUN mkdir -p /home/newuser/app
WORKDIR /home/newuser/app
COPY --from=builder /home/newuser/app /home/newuser/app
RUN ls -a /home/newuser/app
CMD ["php", "-S", "localhost:3000"]
the image build successfully, using:
docker build -t x .
Then I run it with:
docker run -p 3000:3000 x
but when I go to localhost:3000 on the host machine, I don't get a response. The webpage is blank.
Does anyone know why that might happen?
I also tried:
CMD ["sudo", "php", "-S", "localhost:80"]
and
docker run -p 3000:80 x
and a few other variations, still nothing.
Not sure why the PHP static server wasn't working, but I got it working with Node.js static server package:
FROM node:9 as builder
RUN apt-get update && \
apt-get -y install sudo
RUN echo "newuser ALL=(ALL) NOPASSWD:ALL" >> /etc/sudoers
RUN useradd -ms /bin/bash newuser
USER newuser
RUN mkdir -p /home/newuser/app
WORKDIR /home/newuser/app
RUN sudo chown -R $(whoami) $(npm config get prefix)/lib
RUN sudo chown -R $(whoami) $(npm config get prefix)/lib/node_modules
RUN sudo chown -R $(whoami) $(npm config get prefix)/bin
RUN sudo chown -R $(whoami) $(npm config get prefix)/share
RUN sudo chown -R $(whoami) /usr/local/lib
RUN npm set progress=false
RUN npm config set depth 0
RUN npm cache clean --force
COPY dist .
RUN npm install -g http-server
ENTRYPOINT ["http-server", "."]
you build it like so:
docker build -t x .
and then run it like so:
docker run -p 3000:8080 x
My requirement is using openface i need to train the dataset(images) and test each input image from webinterface (PHP) and all this activity should run from docker container.
I am able to achieve the above requirment on ubuntu machine. we are trying to install the complete setup(apache/php & openface) in docker. currently we are unable to invoke the html files from apache server using docker
The following the docker file used to import the project into docker and install apache/PHP. Please let me know if any changes need to be done in the dockerfile.

ADD apache-config.conf /etc/apache2/sites-enabled/000-default.conf
CMD /usr/sbin/apache2ctl -D FOREGROUND
Once the container is started i want the test.html(located in /var/www/html) to be running.
FYI :
command to created docker image
sudo docker build -t myname/apache-test .
command to start the docker container
docker run -p 8080:80 -d <imageid>
I'd suggest to use the official PHP image with a pre-installed Apache installation.
Your project might look like this:
.
├── Dockerfile
└── src
└── index.php
while your Dockerfile consists of this:
FROM php:7.1-apache
# now RUN here your commands to install openface etc.
and your index.php could look like this:
<?php phpinfo();
Then build the image:
docker build -t myapache .
docker run --rm -p 8080:80 -v $(pwd)/src:/var/www/html myapache
http://localhost:8080 shows the php-info page.
You can extend the image to your needs and it's much simpler than your approach. Hope this might help.
If you do not need to install anything else, you can directly use the php:7.1-apache image when creating a new container.
try typing docker ps to get all the processes running in containers.
Then just type docker run -it container-id
It will start the apache server and show the address where it hosted it unless you want to add a different one in /etc/docker/daemon.json (https://docs.docker.com/engine/userguide/networking/default_network/custom-docker0/)
I have built an image for my app with apache, container created from it is working just fine. I am able to see the page on localhost. (file #1: docker-compose.yml)
I push image to docker hub
I recreate a container using another (file #2: docker-compose-prod.yml) for the same app and it's exited immediately without any error, container output was:
Module rewrite already enabled
httpd (pid 1) already running
Here is app service described in docker-compose.yml file #1 which I used for build:
app:
build: .
links:
- db
- memcache:memcached
- search
ports:
#- 8080:80 # when varnish enabled
- 80:80
restart: always
environment:
DB_HOST: db:3306
DB_PASSWORD: *****
SEARCH_HOST: search:9312
MEMCACHE_HOST: memcache:11211
Here is docker-compose-prod.yml, file #2 I used for deployment which contains problem:
app:
image: vendor/app
#restart: always
links:
- db
- memcache:memcached
- search
ports:
#- 8080:80 # when varnish enabled
- 80:80
environment:
DB_HOST: db:3306
DB_PASSWORD: *****
SEARCH_HOST: search:9312
MEMCACHE_HOST: memcache:11211
#networks:
#- proxy
#- backend
Containers of next services are always up and running:
- db
- memcache:memcached
- search
Some details:
I run docker-compose.yml (file#1) from within app directory:
/home/user/app1$ docker-compose up -d
and second file from another directory
/home/user/app2$ docker-compose -f docker-compose-prod.yml up -d
Here is Dockerfile:

source /etc/apache2/envvars
exec apache2 -D FOREGROUND
It happens because really
Module rewrite already enabled
Why does it happen?
When you create container rewrite_module is disabled. And run.sh enable it.
Later, you stop (but not remove) container, and run it again. But run.sh runs everytime when container is starts. And run.sh are trying to load this module again and you receive the error.
You can ignore the error or you can modify run.sh something like:
#!/bin/bash
if [ "$ALLOW_OVERRIDE" = "**False**" ]; then
unset ALLOW_OVERRIDE
else
sed -i "s/AllowOverride None/AllowOverride All/g" /etc/apache2/apache2.conf
if [! httpd -M | grep rewrite_module]; then
a2enmod rewrite;
fi;
fi
source /etc/apache2/envvars
apache2 -D FOREGROUND
I hope I helped you.
Finally I've got it working!
Solution:
# Apache gets grumpy about PID files pre-existing
I added to run.sh following line:
rm -f /var/run/apache2/apache2.pid

$mc = new Memcached();
$mc->addServer("localhost", 11211);
$flag = $mc->add('name','droidos');
echo ($flag)?'y':'n';
echo $mc->getResultCode();
?>
This script returns n47 implying that the memcached server is disabled.
Either my linking is incorrect or memcached has not been started or the memcached container port is not visible in the apache container. SSHing into the memcached container
docker exec -it <container-id> /bin/bash
and running
service memcached status
indicates that the service is not in fact running. So I start it
service memcached start
verify it has started and run the script above again. No joy - I still get an n47 reply rather than the y0 I would like to see. Clearly, I am missing a step somewhere here. I'd be most obliged to anyone who might be able to tell me what that might be.
I think it fails because you're trying to access memcached from the apache container connecting to the localhost of the apache container, while the memcached container is made accessible to the apache one on a different IP address.
This is the line I think is wrong:
$mc->addServer("localhost", 11211);
When you link containers, Docker adds a host entry for the source container to the /etc/hosts file (see the docs about linking).
Therefore you should be able to connect from the apache container to the memcached one using this PHP command:
$mc->addServer("memcached", 11211);
If it doesn't work, check that you can connect to the memcached service from the memcached container itself.
