I tried the approach with tty: true stdin_open: true inside docker-compose.yml and attaching to the container id (following http://www.chris-kelly.net/2016/07/25/debugging-rails-with-pry-within-a-docker-container/) but it just hangs.
I also tried docker-compose run --service-ports web following this article https://blog.carbonfive.com/2015/03/17/docker-rails-docker-compose-together-in-your-development-workflow/ but it also hangs the request when binding.pry
Could supervisord affect this?
Here's the Dockerfile:
FROM ruby:2.3.3
RUN apt-get update -qq && apt-get install -y build-essential libpq-dev supervisor
RUN curl -sL https://deb.nodesource.com/setup_9.x | bash - && apt-get install -yq nodejs
RUN curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -
RUN echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list
RUN apt-get update && apt-get install yarn
RUN mkdir /example
WORKDIR /example
COPY Gemfile /example/Gemfile
COPY Gemfile.lock /example/Gemfile.lock
RUN bundle install
COPY . /example
COPY docker/supervisor.conf /etc/supervisor/conf.d/example.conf
RUN cd client-app && npm install
CMD supervisord -n
And the docker-compose.yml:
version: '3'
services:
db:
image: postgres
web:
build: .
environment:
API_HOST: http://localhost:3000/api
volumes:
- .:/example
ports:
- "3000:3000"
- "4200:4200"
depends_on:
- db
And the supervisor.conf:
[program:rails]
directory=/example
command=rails server -b 0.0.0.0 -p 3000
autostart=true
autorestart=true
[program:npm]
directory=/example
command=/bin/bash -c "yarn && cd client-app && npm run docker-start"
autostart=true
autorestart=true
(assuming you're running postgres something like docker run -d --name=postgres ...)
I would ditch compose and try
docker build -t web .
docker run --link postgres:db -it -p 3000:3000 -p 4200:4200 web
If that fails, I'd punt and
docker run --link postgres:db -it -p 3000:3000 -p 4200:4200 web bash
Then try running rails s, rails c, etc manually within the container.

I have project which used docker-compose to provide environment to developers. The application is running fine on docker-compose build command and running on 0.0.0.0:3000 on docker-compose up command. When I am trying to run the command docker-compose run web rails g uploader or docker-compose run web rails g migration it's show in console thats they successfuly create but when I check project there are no files.
This is my Dockerfile:
# Base image

This one is my docker-compose.yml:

env_file:
- '.env.db'
ports:
- "5432:5432"
volumes:

I had this same problem and solved it by following these steps:
1 - in Dockerfile add the fallowing lines, for be able to create new files:
RUN mkdir /home/web \
&& chown $(id -un):$(id -gn) /home/web
WORKDIR /home/web
2 - in docker-compose.yml web the volume should be .:/home/web or just the same as you call in mkdir
web:
volumes:
- .:/home/web
I hope that solve your problem too
I'm currently using whenever gem for running my Sidekiq worker. It's perfectly fine when I'm running the Sidekiq worker but when I run it in background using cron it's not working.

schedule.rb
set :environment, "development"
every 1.minute do
runner "User.create"
end
When I run docker-compose build then docker-compose up and I access the web image using docker exec -it <container-id> sh
crontab -e returns
# Begin Whenever generated tasks for: /app/config/schedule.rb at: 2019-12-16 03:00:58 +0000

# End Whenever generated tasks for: /app/config/schedule.rb at: 2019-12-16 03:00:58 +0000
It should create a user every minute. I tried running this manually and it managed to create a user. I wonder why it's not running from cron
I have a docker-compose file that runs a few services.
services:
cli:
build:
context: .
dockerfile: docker/cli/Dockerfile
volumes:
- ./drupal8site:/var/www/html/drupal8site
drupal:
container_name: drupal
build:
context: .
dockerfile: docker/DockerFile.drupal
args:
DOC_ROOT: /var/www/html/drupal8site
ports:
- 80:80
volumes:
- ./drupal8site:/var/www/html/drupal8site
restart: always
environment:
APACHE_DOCUMENT_ROOT: /var/www/html/drupal8site/web
mysql:
image: mysql:5.7
ports:
- 3306:3306
volumes:
- ./mysql:/var/lib/mysql
environment:
MYSQL_ROOT_PASSWORD: root
I would like to add another service which will be a container in which I could run CLI commands (composer, drush for drupal, php, etc).
The following Dockerfile was how I initially defined the cli service but it stops right after it is run. How do I define it so it is part of my docker-compose, shares my mounted volume, and I can interactively connect to it and run CLI commands on it ?
FROM php:7.2-cli
#various programs
RUN apt-get update \
&& apt-get install vim --assume-yes \
&& apt-get install git --assume-yes \
&& apt-get install mysql-client --assume-yes
CMD ["bash"]
Thanks,
Yaron
If you want to run automated scripts on docker images this is obviously a job for a ci-pipeline. You can use CloudFoundry or OpenStack to do this.
But there are many other questions in this post:
1.) How can i share my mounted volume:
You can pass a volume with the -v option to a container. e.g.:
docker run -it -d -v $(pwd)/localFolder:/exposedFolderFromDocker mydockerhub/myawesomeimage
2.) Can I interactively connect to it and run CLI commands on it
docker exec -it docker_cli_1 bash
I recommend to implement features of an docker-image to the individual docker-images Dockerfile. For example copying and running a prepared shell-script:
# your Dockerfile
FROM php:7.2-cli
#various programs
RUN apt-get update \
&& apt-get install vim --assume-yes \
&& apt-get install git --assume-yes \
&& apt-get install mysql-client --assume-yes
# individual changes
COPY your_script.sh /
RUN chown root:root /your_script.sh && \
chmod 0755 /your_script.sh
CMD ["/your_script.sh"]
# a folder to expose
VOLUME /exposedFolderFromDocker
CMD ["bash"]
I'm using Docker Toolbox on Windows 10.
I'm starting a server using python manage.py runserver 0.0.0.0:8000
I'm getting the response Starting development server at http://0.0.0.0:8000/
However when I'm going to http://127.0.0.1:8000/ in my browser, it's not working.
Any idea? What should I check?
I've tried docker run -p 8000:8000 my_image but I get Bind for 0.0.0.0:8000 failed: port is already allocated.

I'm new to docker and try to convert my actual web stack in it.
Currently I use this configuration:
varnish -> nginx -> php-fpm -> mysql
I have already convert php-fpm and nginx and now tries varnish.
When I run my image with a command, all is fine but when I put it in docker-compose my container restart indefinitely.
Command:
name="varnish"
cd $installDirectory/$name
docker build -t $name .
docker rm -f $(docker ps -a | grep $name | cut -d' ' -f1)
docker run -d -P --name $name \
-p 80:80 \
--link nginx:nginx \
-v /home/webstack/varnish/:/etc/varnish/ \
-t $name
My docker-compose.yml:
php-fpm:
restart: always
build: ./php-fpm
volumes:
- "/home/webstack/www/:/var/www/"
nginx:
restart: always
build: ./nginx
ports:
- "8080:8080"
volumes:
- "/home/webstack/nginx/:/etc/nginx/"
- "/home/webstack/log/:/var/log/nginx/"
- "/home/webstack/www/:/var/www/"
links:
- "php-fpm:php-fpm"
varnish:
restart: always
build: ./varnish
ports:
- "80:80"
volumes:
- "/home/webstack/varnish/:/etc/varnish/"
links:
- "nginx:nginx"
I have no result with docker logs webstack_varnish_1 and docker ps -a result show:
688c5aace1b3 webstack_varnish "/bin/bash" 16 seconds ago Restarting (0) 5 seconds ago 0.0.0.0:80->80/tcp
Here you can see my Dockerfile:
FROM debian:jessie
# Update apt sources
RUN apt-get -qq update
RUN apt-get install -y curl apt-transport-https
RUN sh -c "curl https://repo.varnish-cache.org/GPG-key.txt | apt-key add -"
RUN echo "deb https://repo.varnish-cache.org/debian/ jessie varnish-4.1" > /etc/apt/sources.list.d/varnish-cache.list
# Update the package repository
RUN apt-get -qq update
# Install varnish
RUN apt-get install -y varnish
# Expose port 80
EXPOSE 80
What I am doing wrong please?
Regards.
Your varnish Dockerfile seems to be missing ENTRYPOINT and/or CMD directives that would actually launch Varnish.
We have found the solution here :
https://github.com/docker/compose/issues/2563
I have to add tty: true to my varnish config.
Regards.
