rails's Introduction

DEPRECATED

This image is officially deprecated in favor of the standard ruby image, and will receive no further updates after 2016-12-31 (Dec 31, 2016). Please adjust your usage accordingly.

For most usages of this image, it was already not bringing in rails from this image, but actually from your project's Gemfile, so the only "value" being added here was the pre-installing of nodejs, mysql-client, postgresql-client, and sqlite3 for various uses of the rails framework.

For example, a Dockerfile similar to the following would be a good starting point for a Rails project using PostgreSQL:

FROM ruby:2.3

RUN apt-get update \
	&& apt-get install -y --no-install-recommends \
		postgresql-client \
	&& rm -rf /var/lib/apt/lists/*

WORKDIR /usr/src/app
COPY Gemfile* ./
RUN bundle install
COPY . .

EXPOSE 3000
CMD ["rails", "server", "-b", "0.0.0.0"]

rails's Issues

concurrent `bundle install`

The bundle install step could likely by dramatically sped up by adding --jobs 4 or some such value.

Issue using boot2docker

Hi, i'm trying to use rails image with boot2docker on OSX, and I have the following error trying to create a rails app:

In file .../activerecord-4.1.5/lib/active_record/tasks/postgresql_database_tasks.rb:

      def structure_dump(filename)
        set_psql_env
        search_path = configuration['schema_search_path']
        unless search_path.blank?
          search_path = search_path.split(",").map{|search_path_part| "--schema=#{Shellwords.escape(search_path_part.strip)}" }.join(" ")
        end

        command = "pg_dump -i -s -x -O -f #{Shellwords.escape(filename)} #{search_path} #{Shellwords.escape(configuration['database'])}"
        raise 'Error dumping database' unless Kernel.system(command)

        File.open(filename, "a") { |f| f << "SET search_path TO #{ActiveRecord::Base.connection.schema_search_path};\n\n" }
      end

      def structure_load(filename)
        set_psql_env
        Kernel.system("psql -q -f #{Shellwords.escape(filename)} #{configuration['database']}")
      end

Almost same thing with mysql.

    def structure_dump(filename)
        args = prepare_command_options('mysqldump')
        args.concat(["--result-file", "#{filename}"])
        args.concat(["--no-data"])
        args.concat(["#{configuration['database']}"])
        unless Kernel.system(*args)
          $stderr.puts "Could not dump the database structure. "\
                       "Make sure `mysqldump` is in your PATH and check the command output for warnings."
        end
      end

      def structure_load(filename)
        args = prepare_command_options('mysql')
        args.concat(['--execute', %{SET FOREIGN_KEY_CHECKS = 0; SOURCE #{filename}; SET FOREIGN_KEY_CHECKS = 1}])
        args.concat(["--database", "#{configuration['database']}"])
        Kernel.system(*args)
      end

So, without these utils you cannot run db:structure tasks.

Use non-root user

As suggested in best practices.

It also makes bundler complain.

Copied from #223 under docker-library/docs

Host key verification failed

I have some private repositories being used in my Gemfile but cannot access them when this image runs bundle install.

What is the proper way to get ssh keys verified with Github using boot2docker and this library?

Failing on build

I used the exact Dockerfile that was in this repository, it would not run rails and errored out on that command. So I changed the base image from ruby to rails. Now everything builds and runs, but the app is still not available. Any help would be much appreciated.

Logs go to a file instead of STDOUT

I hadn't played around much with the rails image before this week, but I noticed that the logs are be written to the default logs/#{Rails.env}.log file instead of STDOUT.

I think the fix will need to be made for each app that is based on this image (or pretty much any other Dockerized Rails app), so I don't think there's anything to be done in the image itself. I believe the only thing that should be done is to document the issue over at docker-library/docs, so let me know if I should have opened the issue there. At least having the issue in this repo will help people find it if they search for the problem.

The Rails docs show a quick & dirty approach to logging to STDOUT: http://guides.rubyonrails.org/debugging_rails_applications.html#the-logger

There are also things like Heroku's rails_stdout_logging gem: https://github.com/heroku/rails_stdout_logging

“Don't run Bundler as root.”

Maybe it can be solved by using --system

Also IIRC avoiding to run as root inside the container's a good practice security-wise (I may be wrong or out of date tho)

ONBUILD conflicts with items that need to be installed first

ONBUILD is running "bundle install" as soon as my Dockerfile is run. This appears to be correct behavior.

But one of my gems, 'tiny_tds' requires 'freetds' it to be installed first. I can't install it first because ONBUILD is running first. The same thing would happen if Postgres or MySQL were not installed before the bundle install.

Is there a way to handle this scenario?

Ruby 2.3

Is there any plan to use ruby 2.3?

Thanks

Typo in Rails Image Readme

https://registry.hub.docker.com/_/rails/

The onbuid tag expects a Gemfile.lock in your app directory.

Should read:

The onbuild tag expects...

Undefined method for an in-built Ruby method - only occuring in Docker images

I have the following Image:
FROM rails:4.2.0

Copy Rails app

COPY . /apps
WORKDIR /apps
RUN bundle install
VOLUME ["/var/log/spree-vend"]
EXPOSE 3000

And have the following undefined method error for the built-in PP method, occurring only, within the Docker image called within a controller..

bundler error with any gem from git

When I have gems, spefcified in gemfile with:git, running container fails with bundler error.

The rails account in Docker Hub

Hi, I have tried to figure this out through different channels without luck. Let my try here, but feel free to close if you can't help.

I am a Rails core team member, and want to register a "rails" account to share an image for Rails core development. That is, someone willing to contribute a patch to Rails would fetch the image and create containers where all is set to tinker and run the test suites. This would be an alternative to our current rails-dev-box. As you see it has a different goal than this official rails image.

Docker Hub says the "rails" username is taken (same for an organization namespace), but https://hub.docker.com/u/rails/ yields a 404. Could it be the case that Docker Hub disallows accounts named as one of their official repositories?

Don't install development/test dependencies.

Shouldn't the bundle command be bundle install --without development test? Or at least allow some variant tags that do this?

rails:onbuild does not work with engines in subfolders

Hi,
In our Rails application we have engines which are referenced in our Gemfile e.g:

gem 'foo', path: 'engines/foo'

This is problematic since the rails:onbuild image does ONBUILD COPY . /usr/src/app after ONBUILD RUN bundle install hence producing this kind of error:

The path `/usr/src/app/engines/foo` does not exist.
2014/12/17 11:15:48 The command [/bin/sh -c bundle install] returned a non-zero code: 13

I am not an expert at Rails apps but I think this is a common practice ; I there a specific reason I don't know about for running bundle install before copying the files ?
Can someone tell me if we are doing something wrong with our Gemfile ?

If there is no specific reason, since Gemfile and Gemfile.lock are generally kept under version control, I'd suggest to replace:

ONBUILD COPY Gemfile /usr/src/app/
ONBUILD COPY Gemfile.lock /usr/src/app/
ONBUILD RUN bundle install

ONBUILD COPY . /usr/src/app

ONBUILD COPY . /usr/src/app
ONBUILD RUN bundle install

Tell me what you think ; I'd be pleased to make a PR for this.

I was able to solve is by using the contents of the dockerfile and changing ruby from 2.2 to 2.1.5

I understand its not your issue but informing you so it can help !

Need libxml2-dev libxslt1-dev to build rails

Not sure which image your From ruby:2.2 stands for. I suppose it would be the image build from here: https://github.com/docker-library/ruby/tree/master/2.2

Then I tried to build on top of which I've build with wheezy image, then I found the following patch was needed to finish building.

Rails 4.2 Not Accessible on Host

I used the onbuild image to create a new Rails 4.2 application but was having difficulty accessing it (Boot2Docker on OSX). It turns out there was a change with the release 4.2 so that by default in development mode applications listen on localhost vs 0.0.0.0. Essentially this means (to the best of my understanding) that the web server is only accessible from inside of the running container. In order to access my server externally (ie. on the host machine) I had to do something like: rails s -b 0.0.0.0 Perhaps this option should be added to the default command in the onbuild image?

Any ETA on Ruby 2.1.4 / Rails 4.1.7 Docker Image Availability?

Hi there.
It seems you've done the work already but can't seem to be able to find that 2.1.4 & 4.1.7 support on the official docker repo:

https://registry.hub.docker.com/u/library/rails/

Thanks in advance.

More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

'Connection timed out' with bundle install

I ran into this error on a company server probably protected by proxy and firewall. I could not change the configuration. This was the error output:

fatal: unable to connect to github.com:
github.com[0: 192.30.252.128]: errno=Connection timed out

Retrying git clone 'git://github.com/rweng/jquery-datatables-rails.git' "/usr/local/bundle/cache/bundler/git/jquery-datatables-rails-b8d699e208e47fe51869a7aebe3d593ff0672f4a" --bare --no-hardlinks --quiet due to error (2/4): Bundler::Source::Git::GitCommandError Git error: command `git clone 'git://github.com/rweng/jquery-datatables-rails.git' "/usr/local/bundle/cache/bundler/git/jquery-datatables-rails-b8d699e208e47fe51869a7aebe3d593ff0672f4a" --bare --no-hardlinks --quiet` in directory /usr/src/app has failed.

I could solve this by globally change git:// into https:// in the Dockerfile before the ONBUILD instructions:

# solves 'Connection time out' on server in company domain.
RUN git config --global url."https://".insteadOf git://

I do not know if this works in all situations, however.

Can this be used in production?

Am I correct in saying this uses web brick? And if so does this mean that is should not be used in production?

Thanks in advance
