I'm running docker-compose to run my application which listen to REST api calls.
For some reason it is not accessible from outside.
I don't understand what am I doing wrong.
Here is the configuration:
version: '3.4'
services:
rabbitmq:
image: rabbitmq:3-management
ports:
- 5672:5672
- 15672:15672
my-server:
image: my-server
build:
context: .
dockerfile: ./apiserver/Dockerfile
ports:
- 5000:5000
restart: on-failure
depends_on:
- rabbitmq
and my Dockerfile is:
FROM ubuntu:16.04
RUN apt-get update -y && \
apt-get install -y python-pip python-dev
# We copy just the requirements.txt first to leverage Docker cache
COPY ./requirements.txt /app/requirements.txt
WORKDIR /app
RUN pip install -r requirements.txt
COPY . /app
EXPOSE 5000
ENTRYPOINT [ "python" ]
CMD [ "app.py" ]

Im running a docker container where i copy the content of current folder in /app in the container.
Then I put in a volume /app/media folder of the container.
However, when the volume is already created from a previous docker-compose build, i dont find all the new files put in my ./media folder, supposed to be copied to /app/media in the container...
Therefore i'm wondering how docker is populating the volume ? Is it not supposed to check in the container folder new files and put them in the volume?
I had the issue first and it was /media folder in the .dockerignore file, but now it's doing this again with other files in /media folder
Following What is the right way to add data to an existing named volume in Docker? I ve tried to do :
docker run -v mediafiles:/data --name helper busybox true
cd ./media && docker cp . helper:/data
docker rm helper
And it is now working
Thank you

If the volume is new, then docker will copy any files in the image to the new volume.
If the volume isn't new, then nothing is copied and you get the existing, old, contents of the volume.

I want to view the apps from mobile devices. I have tried to use the ip address of my laptop but i still cant accessed to the apps from mobile devices. I can run the apps locally in my laptop but not in other devices although they are using the same network WIFI. I have tried to add ENV HOST 0.0.0.0 which helps to solve connection outside but it still cannot be accessible in my mobile devices. Is there any solution for this ?

I am building my first customs Docker with Docker compose and I feel I am very close to finishing it but I have having an issue with what seem to be the entrypoint
FYI i am tryng to deploy a django app with postgres, nginx, certbot, letsencrypt
this is what I am seeing:
certbot_1 | /data/entrypoint.sh: exec: line 14: certbot: not found
nginx_1 | /data/entrypoint.sh: exec: line 14: run: not found
EDIT: I was able to make them run with the editted code but Ngnix exits with a code 0 and I don't know why and wont run
I have tried changing path with no luck
I am not sure what I am doing wrong
any advice you can provide would be great!

roughly based of this guide:
I am trying to setup Docker and geodjagno. Upon docker-compose up I have this following error:
django.core.exceptions.ImproperlyConfigured: Could not find the GDAL library (tried "gdal", "GDAL", "gdal2.2.0", "gdal2.1.0", "gdal2.0.0", "gdal1.11.0", "gdal1.10.0", "gdal1.9.0"). Is GDAL installed? If it is, try setting GDAL_LIBRARY_PATH in your settings.
GDAL is a library that can be found in this image wooyek/geodjango

Try adding the following in your Dockerfile:
RUN apt-get update &&\
apt-get install -y binutils libproj-dev gdal-bin
You can add the following to your docker file
# Install GDAL dependencies
RUN apt-get install -y libgdal-dev g++ --no-install-recommends && \
apt-get clean -y
# Update C env vars so compiler can find gdal
ENV CPLUS_INCLUDE_PATH=/usr/include/gdal
ENV C_INCLUDE_PATH=/usr/include/gdal
I tried to build a container used docker-compose. So I wrote the dockerfile and docker-compose.yml like following:
dockerfile
FROM ubuntu:latest
RUN apt-get update
RUN apt-get install -y expect
RUN apt-get -y install software-properties-common
RUN apt-add-repository ppa:ondrej/php
RUN apt-get -y install php7.1 php7.1-fpm
RUN apt-get install php7.1-mysql
RUN apt-get -y install nginx
RUN apt-get -y install vim
COPY default /etc/nginx/sites-available/default
COPY www.conf /etc/php/7.1/fpm/pool.d/www.conf
COPY test /var/www/html/test
CMD service php7.1-fpm start && nginx -g "daemon off;"
docker-compose.yml
version: '3'
services:
web:
build:
context: .
dockerfile: Dockerfile
ports:
- "3011:80"
When I run following command, the php7.1-fpm is run success.
docker-compose build
docker-compose up --force-recreate -d
But I want to move the CMD from dockerfile to docker-compose, so I changed the file like following:
docker-compose.yml
command: service php7.1-fpm start && nginx -g "daemon off;"
But this time php7.1-fpm is not running.
How to fix this issue, so that I can run php7.1-fpm in docker-compose.yml?
you can not use service php7.1-fpm start in your Dockerfile, because container is just a process, not a real virtual machine, main process down and others will down neither
docker suggest you to divide them in different container, php-fpm, nginx, single image single container
solution:
