I've been trying to build my Docker image:
docker build -t <tag> -f Dockerfile.production .
However, this hangs while bundling.
I have tried bundling with:
DEBUG_RESOLVER=true bundle install --verbose
Running bundle on my host machine works fine - only the Docker image has this problem.
Attached is my Dockerfile:
FROM cimg/ruby:2.7.4-node
LABEL maintainer=budgeneration#gmail.com
SHELL ["/bin/bash", "-c"]
USER root
RUN sudo apt-get update && \
apt-get install -y nodejs npm libvips-tools libsodium-dev \

python3-distutils \
rsyslog --no-install-recommends
# Other tools not related to building by still required.
RUN sudo apt-get install -y ffmpeg gifsicle
USER circleci
# Install all gems first.
# This hits the warm cache if unchanged so bundling is faster.
COPY Gemfile* /tmp/
WORKDIR /tmp
RUN gem install sassc-rails -v 2.1.2
RUN gem install bulma-rails -v 0.9.1
RUN bundle config set without 'development test' \
&& bundle install --verbose \
&& bundle binstubs railties
# Remove yarn (the other yarn)
RUN apt-get purge cmdtest
RUN yarn global add mjml
WORKDIR /sapco
# First we copy just Yarn files, to run yarn install
COPY package.json /sapco
COPY yarn.lock /sapco
RUN yarn install
WORKDIR /sapco
# Now copy everything
COPY . /sapco
EXPOSE 3000
Any tips to try to debug this further?
I have managed to resolve this issue but not sure why:
I changed my base image file to FROM circleci/ruby:2.7.4-buster-node and the bundling step continues fine.

I am having issues deploying a Ruby on Rails App to ECS Fargate. When I build the image locally (the same way it is done in the pipeline). I can easily start the web service with this command ["bundle", "exec", "unicorn", "-c", "config/unicorn.rb"]. However, running this same image in Fargate returns this: 2022-07-27 15:46:33bundler: failed to load command: unicorn (/usr/local/bundle/bin/unicorn)
Here is my Docker file:
FROM ruby:2.6.7
RUN apt-get update -qq && apt-get install -y nodejs postgresql-client sudo
WORKDIR /app
ENV RAILS_ENV="staging"
ENV NODE_ENV="staging"
ENV LANG="en_US.UTF-8"
ENV RACK_ENV ="staging"
ENV BUNDLE_WITHOUT='development:test'
ARG GITHUB_TOKEN
RUN gem install bundler -v '2.2.28'
RUN bundle config https://github.com/somename/somerepo someuser:"${GITHUB_TOKEN}"
COPY . /app
RUN rm -rf /app/tmp
RUN mkdir -p /app/tmp
RUN bundle install
RUN bundle exec rails assets:precompile
EXPOSE 3000
The CMD is missing from Docker because its'a added in the task definition. Has anyone run into this issue? I've tried a number of different approaches, but am unsure of what is being changed locally running and running in Fargate.
Update
Looking into this issue further and found some more information that will need to be updated here.
I am using CircleCI to build and push this image to ECR. The issue seems to be that when created in CircleCI, any artifacts created by the bundle install become unreachable on run time and Docker is unable to run any gems because the GEM path is not even accessible to the root user. I pulled the image created by CircleCI Docker, locally, and confirmed the same errors. EXECing into the container and running chmod 755 -R /usr/local/bundle/bin/ and then executing the bundle exec to start the service, properly starts unicorn.
Next Steps
As a result, I attempted to add those changes into the Dockerfile on build and the same behavior still persists.
RUN bundle install
RUN chmod 755 -R /usr/local/bundle/bin/
Then I tried changing permissions in an entrypoint script and the container won't start at all.
Finally figured this out a few days ago. The answer is to add VOLUME arguments at the end of your Dockerfile. This will maintain persistence with any changes you have made. My final Dockerfile:

I'm trying to deploy the following container on google cloud app engine using gcloud app deploy, it's the meanjs.org vanilla image. It uses a dockerfile, I'm new to docker and I'm trying to learn it on the fly, so if anyone can help that'd be great, thanks.
It looks as if the install of node via the dockerfile fails, I've checked node's documentation on github, and nothing has changed syntactically to what is in the existing dockerfile. I will attempt to recreate on my local workstation this morning, and will update this query shortly.
the errors are as follows..first docker error second errorbuild fail error

Okay, so after much wrestling unsuccessfully trying to install docker on windows, I went back to the dockerfile to try and identify the core issue here. Fortunately I find a solution as follows..
NodeJS is attempting to install on Ubuntu.
In the dockerfile at the root of the app
Ubuntu version is configured as:
FROM ubuntu:latest
simply change it to:
FROM ubuntu:14.04
I'm not sure if this is the best version to use for the build but it seems to be running successfully. Please feel free to amend/recommend an alternative solution. I'm new to Docker so pls be kind.
I'm really new to Docker and would like to create a container that has all my Ruby on Rails website and its dependencies in it. I read TONS of documentations and how-to's to do it but I keep struggling.
Since I use Rubymine, there is a built-in tool that allows you to Dockerize the current project you're in from the Dockerfile you created in it. However, I keep having the error "npm not found while NodeJS should be installed.
Here is my Dockerfile:
FROM ruby:2.4.3
MAINTAINER Jaeger
RUN apt-get update -qq && apt-get install -y build-essential nodejs
RUN mkdir -p /app
WORKDIR /app
COPY package.json /app
RUN npm i -g yarn && yarn
COPY Gemfile Gemfile.lock ./
RUN gem install bundler && bundle install --jobs 20 --retry 5
RUN yarn
COPY . ./
EXPOSE 3000
CMD ["bundle", "exec", "rails", "server", "-b", "0.0.0.0"]
The ultimate goal should be that, since I use Webpacker and React in it (well it's a dummy project for a test, but the real website has this), I would like to install Yarn, and make Yarn install all the depencies.
I found some other people that had the same problem but got lost trying to understand the Docker layers concept and trying to copy some codes that didn't work either
You need to explicitly install node / npm in your container before running npm install. Add this to your Dockerfile.
RUN apt-get update && apt-get install -y curl
RUN curl -sL https://deb.nodesource.com/setup_8.x | bash -
RUN apt-get update && apt-get install -y nodejs
Another solution (which might be cleaner) would be to first mount / setup the working directory before installing the dependencies:
FROM ruby:2.4.3
MAINTAINER Jaeger
RUN mkdir -p /app
WORKDIR /app
RUN apt-get update -qq && apt-get install -y build-essential nodejs

I’m trying to build docker image with a configuration in Dockerfile:
FROM ubuntu
MAINTAINER axiom88guru(axiom88guru#gmail.com)
Configuration for app below.
Run upgrades
RUN apt-get update
Install basic packages
RUN apt-get update -qq && apt-get install -y build-essential libpq-dev nodejs
Install Ruby
RUN apt-get -qq -y install ruby-full
RUN gem install bundler --no-ri --no-rdoc
RUN gem install foreman
Install rails-new-docker
WORKDIR /app
RUN git clone https://github.com/axiom88-guru/rails-docker.git /app
RUN bundle install --without development test
Run rails-new-docker
ENV SECRET_KEY_BASE dockerkeybase
ENV RAILS_ENV production
EXPOSE 5959
CMD foreman start -f Procfile
When I run these commands in bash they work as expected, but not during docker build:
Removing intermediate container 344e99851852
Step 8/14 : WORKDIR /app
—> 3c204a395f23

Step 9/14 : RUN git clone https://github.com/axiom88-guru/rails-docker.git /app

/bin/sh: 1: git: not found
The command ‘/bin/sh -c git clone https://github.com/axiom88-guru/rails-docker.git /app’ returned a non-zero code: 127
Could anyone help me find out the solution please?
Need to have git installed since the base ubuntu image provides only a minimal set of installed packages (this is done to keep image size small).

This version should work. I just added git to the first apt-get install step.
I have a RoR app that uses imagemagick specified in the Gemfile. I am using Docker's official rails image to build my image with the following Dockerfile:
FROM rails:onbuild
RUN apt-get install imagemagick
and get the following error:
Cant install RMagick 2.13.2. Cant find Magick-config in /usr/local/bundle/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
Now, that's probably because the imagemagic package is missing on the OS, even though I specified it in my Dockerfile. So I guess the bundle install command is issued before my RUN apt-get command is issued.
My question - using this base image, is there a way to ensure imagemagic is installed prior to bundling?
Do I need to fork and change the base image Dockerfile to achieve that?
you are right, the ONBUILD instructions from the rails:onbuild image will be executed just after the FROM instruction of your Dockerfile.
What I suggest is to change your Dockerfile as follow:
FROM ruby:2.2.0
RUN apt-get install imagemagick
# throw errors if Gemfile has been modified since Gemfile.lock
RUN bundle config --global frozen 1
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
RUN apt-get update && apt-get install -y nodejs --no-install-recommends && rm -rf /var/lib/apt/lists/*
RUN apt-get update && apt-get install -y mysql-client postgresql-client sqlite3 --no-install-recommends && rm -rf /var/lib/apt/lists/*
COPY Gemfile /usr/src/app/
COPY Gemfile.lock /usr/src/app/
RUN bundle install
COPY . /usr/src/app
EXPOSE 3000
CMD ["rails", "server"]
which I made based on the rails:onbuild Dockerfile moving down the ONBUILD instructions and removing the ONBUILD flavor.
Most packages clean out the cache to save on size. Try this:
apt-get update && apt-get install imagemagick
Or spool up a copy of the container and look for yourself
docker run -it --remove <mycontainernameorid> /bin/bash
The --remove will ensure that the container is removed after you exit the shell. Once in the shell look for the package binary (or dpkg --list)
