I have a ruby script that fails the GitLab CI build with:
/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- git (LoadError)
The ruby script:
require 'git'
Here's the .gitlab-ci.yml file:
image: gitlab/gitlab-ce:latest
job1:
script:
- apt-get update && apt-get -y install ruby && apt-get install git
- gem install git
- ./script.rb
I've also tried adding a gemfile with the git gem and running:
image: gitlab/gitlab-ce:latest
job1:
script:
- apt-get update && apt-get -y install ruby && apt-get install git
- gem install bundler
- bundle install
- ./script.rb
But I get the same error
So it was quite simple.
Needed to sudo the gem install:
image: gitlab/gitlab-ce:latest
job1:
script:
- apt-get update && apt-get -y install ruby && apt-get install git
- sudo gem install git
- ./script.rb

I can not install ruby's gems on alpine docker image. I've tried different approaches from other questions to solve ERROR: While executing gem ... (Gem::FilePermissionError), but there are solutions either for Ubuntu or for Mac OS.
Part of docker file code:

This seems to be a problem with docker versions earlier than 20.10.4, and at the time of writing this, DockerHub runs an older version.
Option 1:
If you have control over the version of your docker engine, upgrade it to the latest version (comments suggest at least version 20.10.4).
Option 2:
Use FROM alpine:3.13.
With the latest alpine (3.14) it breaks.
Option 3:
Use the official ruby alpine image. I tested with FROM ruby:3-alpine.

You don't generally use version managers like rbenv in Docker. There are a couple of reasons for this. One is that an image usually only contains a single application and its single runtime, so you'd never have more than one Ruby in an image and therefore there's no need to switch. A second is that most common paths of running containers (including docker run and the Dockerfile RUN directive) don't look at shell dotfiles like .bashrc or /etc/profile, so the version manager setup will never get run.
TruffleRuby is distributed (among other ways) as a standalone tar file so you can just install that in your Dockerfile. I'd make the Dockerfile look roughly like:
FROM debian:buster-slim
# Install the specific dependency packages TruffleRuby recommends
# (build-essential is much larger but might actually be necessary)
RUN apt-get update \
&& DEBIAN_FRONTEND=noninteractive \
apt-get install --no-install-recommends --assume-yes \
curl \
gcc \
libssl-dev \
libz-dev \
make
# Download and unpack TruffleRuby
ARG TRUFFLERUBY_VERSION=20.3.0
ENV PATH /opt/truffleruby-$TRUFFLERUBY_VERSION-linux-amd64/bin:$PATH
RUN cd /opt \
&& curl -L https://github.com/oracle/truffleruby/releases/download/vm-$TRUFFLERUBY_VERSION/truffleruby-$TRUFFLERUBY_VERSION-linux-amd64.tar.gz | tar xz \
&& /opt/truffleruby-$TRUFFLERUBY_VERSION-linux-amd64/lib/truffle/post_install_hook.sh
# Now build and install your application
RUN gem install bundler:2.2.4
WORKDIR /app
COPY Gemfile Gemfile.lock ./
RUN bundle config set --local deployment 'true'
RUN bundle config set --local without 'development test'
RUN bundle install
COPY . .
ENTRYPOINT ["bundle", "exec"]
EXPOSE 3000
CMD ["rails", "start"]
You can reasonably split this into two separate Dockerfiles. End the first one before the "build and install your application" comment, and build it with docker build -t myname/truffleruby:20.3.0 -f Dockerfile.truffleruby .. Then the second one can begin with FROM myname/truffleruby:20.3.0 in the same way as the standard Docker Hub ruby image.
Does the same work with CRuby?
I'd suspect RUN doesn't read shell files, so PATH needs to be modified.
RUN git clone https://github.com/sstephenson/rbenv.git /root/.rbenv
...
RUN /root/.rbenv/plugins/ruby-build/install.sh
ENV PATH /root/.rbenv/bin:$PATH
seems a bit weird, is rbenv cloned and installed in the same place?
I would skip rbenv in Docker, and instead just:
RUN ruby-build truffleruby ~/.rubies/truffleruby
ENV PATH $HOME/.rubies/truffleruby/bin:$PATH
Here's how my config looks like:
deploy_hybrid:
stage: deploy
before_script:
- apt update -qq
- apt install ruby-full -qq
- gem install cocoapods
- pod repo update
However, it's always installing Ruby 2.1
WARNING: apt does not have a stable CLI interface yet. Use with
caution in scripts. The following extra packages will be installed:
libruby2.1 libtcl8.5 libtcltk-ruby libtk8.5 libxft2 libxss1 ri ruby

I am using Ruby version 2.2.0 in my Rails Application and Rails version is 4.2.0.
Currently, Project is built through docker, so I am thinking of to upgrade the ruby version with 2.4.0 version.
I believe I need to change the docker image to upgrade the ruby version.
I already check a few of the articles but didn't get enough information.
Docker file
FROM ruby:2.2.0
RUN apt update && \
apt install -y --no-install-recommends \
git \
curl \
gnupg2 \
libpq-dev \
libmysqlclient-dev \
nodejs \
graphviz \
&& rm -rf /var/lib/apt/lists/*
Once ruby version upgraded then I will upgrade the rails version.
Any help will be appreciated.
You can always build your own Docker image as such:
FROM ubuntu
RUN apt-get update
RUN apt-get install -y build-essential wget
RUN wget --no-check-certificate -O ruby-install.tar.gz https://github.com/postmodern/ruby-install/archive/master.tar.gz
RUN tar -xzvf ruby-install.tar.gz
RUN cd ruby-install-master && make install
RUN cd /
RUN rm -rf ruby-install-master && rm -rf ruby-install.tar.gz
RUN ruby-install --latest
RUN ruby-install -i /usr/local/ ruby 2.4.0 -- --disable-install-doc
RUN gem update --system --no-document
RUN gem install bundler --force
depends on how one manages ruby application and ruby version. here are few things i would offer to check:
update Gemfile if bundler is used
$ cat Gemfile | head -n 1
ruby '2.4.0'
update .ruby-version if rbenv or [rvm][3] is used
$ cat .ruby-version
2.4.0
update Dockerfile if docker is used
$ cat Dockerfile | grep FROM
FROM ruby:2.4.0
I am trying to deploy our app to Heroku and our settings in .gitlab-ci.yml looks like
staging_heroku:
stage: deploy
script:
- git remote add heroku https://heroku:$STAGING_HEROKU_KEY#git.heroku.com/staging-myapp.git
- git push -f heroku master
This is what we see in logs

These runners do not even have apt-get and so I can not install gem.
I even tried git command, but even that is not found. Can someone help?
You need to install ruby and ruby-dev first! (and rubygems-integration for Debian 8)
staging:
type: deploy
script:
- apt-get update -yq
- apt-get install -y ruby ruby-dev rubygems-integration
- gem install dpl
- dpl --provider=heroku --app=teeth-taroko --api-key=$HEROKU_STAGING_API_KEY
only:
- develop
