Build Project inside docker container and share folder in mounted - docker

Question

I use docker-compose to build my containers and on a state I checkout private repository and I build the project inside container with composer.
I have the following structure
- docker-project
-- docker //here I keep the containers
--- apache
---- Dockerfile // the content what I posted
-- docker-compose.yml
-- src //this is the mounted folder where I can work on project
After build I would expect that the build project would show up in the mounted folder but instead I get empty folders here is my compose yml
apache:
container_name: apache2
build:
context: ./docker/apache
ports:
- 80:80
- 443:443
links:
- database
restart: always
volumes:
- ./src:/var/www/
- ./docker/logs/apache2/:/var/log/apache2/
- ~/.ssh/id_rsa:/root/.ssh/id_rsa
- ./docker/apache/sites/:/etc/apache2/sites-enabled
and here I have the docker file

RUN rm -rf /var/www/project
WORKDIR /var/www/
RUN git checkout path/to/repo
RUN ls -l /var/www
WORKDIR /repo
RUN composer install
RUN ls -l
on docker-compose build I see that the project will be builded but on
docker-compose upthe folder is empty
What I'm missing in this case?

Answer 1

You are mounting a volume on /var/www when starting the container.
/var/www will be the same as ./src/www on the host machine, replacing anything that was added to /var/www during the build of the image.
Consider using the composer docker image or make sure to install the dependencies to another directory. Check out the vendor_dir key in composer.json
Example:
composer.json
{
"require": {
},
"config": {
"vendor-dir": "/var/www/vendor/"
}
}
Docker image build:
...
RUN mkdir -p /var/www/vendor/
COPY composer.json /var/www/vendor/
RUN cd /var/www/vendor/ && composer install
RUN mkidr -p /var/www/app
...
docker-compose.yml
volumes:
- ./src:/var/www/app

I could give a way of currently we are working. Rather cloning the repo like this what we do, we clone the repo in the local machine.
You have standard docker image that you have created from
php:7.1-apache with required softwares that you need to run the project.
Then you clone your project to you host machine.(think into src folder)
You run the composer install locally.
Then as you have defined the docker-compose.yml mount your src folder into /var/www/
