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

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
I am creating a Dockerfile and somehow I can't install the ruby version I need: 2.7.2 . Since I just need this version, I don't want to install ruby through rbenv or rvm. I tried "apt install ruby", "apt get install ruby 2.7.2", "apt install ruby-full" and the version installed is always 2.5.1. Any Ideas?
This is how my Dockerfile looks like:
FROM nvidia/cuda:10.1-base-ubuntu18.04
LABEL version="0.0.1"
LABEL maintainer="mjg"
RUN apt update \
&& apt install -y python3.6 python3-pip \
&& apt install -y ruby
WORKDIR /cvlib
RUN pip3 install --upgrade pip; \
pip3 install opencv-python tensorflow cvlib; \
apt install -y libsm6 libxext6 libxrender-dev libgl1-mesa-glx; \
apt remove -y python3-pip
WORKDIR /app
COPY . .
VOLUME [ "/app/blurred-images", "app/source-images" ]
Using apt install ruby will install ruby version from distribution repository, which in your case in ruby 2.5.1. You should consider installing it with ruby version managers like rbenv or rvm, because they allow you to specify specific version that you want to install.
I am running the following command in my Dockerfile:
RUN apt-get update && apt-get -y install gnupg2
RUN gpg2 --keyserver hkp://keys.gnupg.net --recv-keys D39DC0E3
RUN curl -sSL https://get.rvm.io | bash -s
RUN /bin/bash -l -c ". /etc/profile.d/rvm.sh && rvm install 2.3.1 && rvm use --default 2.3.1 && gem install bundler"
# some more code
ENTRYPOINT ["/entrypoint.sh"]
In my entrypoint.sh, I am running bundle install. But it's throwing error:
bundle not found
Upon further investigation, I found that none of the dependencies installed during Docker build time seem to be available at container run time. I am probably missing something very basic. Help very appreciated.
The entrypoint.sh does not load rvm, so it doesn't see the rvm-installed Ruby or its bundler.
Load rvm in the entrypoint.sh by adding . /etc/profile.d/rvm.sh and rvm use .. before Ruby is used.
New to ruby and bundler here.
I am installing them in a docker image with this docker file:
FROM alpine:3.5
# Install Ruby, Ruby Bundler and other ruby dependencies
RUN apk add --update \
ruby ruby-bigdecimal ruby-bundler \
ca-certificates libressl \
libressl-dev build-base ruby-dev \
ruby-rdoc ruby-io-console ruby-irb; \
\
&& bundle config build.nokogiri --use-system-libraries; \
&& bundle config git.allow_insecure true; \
\
&& gem install json foreman --no-rdoc --no-ri; \
&& gem cleanup; \
&& rm -rf /usr/lib/ruby/gems/*/cache/*; \
&& apk del libressl-dev build-base ruby-dev; \
&& rm -rf /var/cache/apk/* /tmp;
CMD ["bundle"]
When I run do a docker run I get:
Don't run Bundler as root. Bundler can ask for sudo if it is needed,
and installing your bundle as root will break this application for all
non-root users on this machine.
Could not locate Gemfile or .bundle/ directory
How do I resolve this? I just want to install ruby and ruby-bundle and be done with this ...
There are pre built ruby images (e.g Alpine 3.11 Ruby 2.7) that include bundler. It's easier to start with them as they generally use the current "best practices" to build.
Notice that they set the BUNDLE_SILENCE_ROOT_WARNING environment variable with ENV directive in the image build to remove that root warning.
You normally wouldn't run bundler as the CMD for a container either, you might run bundler during a RUN image build step though.
Running containers as non-root users is not a bad idea in any case. Use the USER directive to change that.
FROM ruby:2.7
WORKDIR /app
ADD . /app/
RUN set -uex; \
bundle install; \
adduser -D rubyapp; \
mkdir -p /app/data; \
chown rubyapp /app/data
USER rubyapp
CMD [ "ruby", "whatever.rb" ]
I have encountered 3 problems while following this guide to installing Metasploit Framework on Ubuntu and Debian:
1) After installing proper version of ruby, there is a command given for installing Ruby libraries: sudo gem install bundler. When I typed that in and hit enter, it says "command not found". After some researching on the internet, I decided to remove sudo and try again. So I've entered gem install bundler and it worked fine. Will this cause any problems?
2) After installing Metasploit Framework, there is a command given to install the required gems and versions:
cd metasploit-framework
bundle install
But when I tried that, I got this error:
rbenv: version '2.1.6' is not installed
I really don't know what to do next (But I moved on).
3) Probably due to the previous problems, in the end when I executed msfconsole command, it said
could not find rake-10.4.2 in any of the sources.
run bundle install to install the missing gems
But the bundle install doesn't help either, because when I run that it says
Could not locate Gemfile or .bundle/directory
Any help would be appreciated.
EDIT: When I asked the person himself who had written the guide, regarding this, he told me to select the version of ruby I had just installed with either rebind or RVM before installing bundler, and then to run the bundle install. Could you please list the commands to do so? I am really new to Linux!
step 1 :
sudo apt-get update
sudo apt-get upgrade
step 2 :
Install dependent packages
sudo apt-get install build-essential libreadline-dev libssl-dev libpq5 libpq-dev libreadline5 libsqlite3-dev libpcap-dev openjdk-7-jre git-core autoconf postgresql pgadmin3 curl zlib1g-dev libxml2-dev libxslt1-dev vncviewer libyaml-dev curl zlib1g-dev
step 3 :
Install Ruby
curl -L https://get.rvm.io | bash -s stable
source ~/.rvm/scripts/rvm
echo "source ~/.rvm/scripts/rvm" >> ~/.bashrc
source ~/.bashrc
rvm install 2.1.6
rvm use 2.1.6 --default
ruby -v
step 4 :
Install and configure postgresql
sudo apt-get install postgresql
sudo -s
su postgres
createuser msf -P -S -R -D
createdb -O msf msf
exit
Step 5 :
Install Metasploit Framework
cd /opt
sudo git clone https://github.com/rapid7/metasploit-framework.git
sudo chown -R `whoami` /opt/metasploit-framework
cd metasploit-framework
cd metasploit-framework
sudo bash -c 'for MSF in $(ls msf*); do ln -s /opt/metasploit-framework/$MSF /usr/local/bin/$MSF;done'
Still if you are facing any issue, you can download the iso or vm image from kali wesbite
I have this problem in kali after install metasploit-framework, and i can't run msfconsole. I solved the problem using the following method:
At change your directory to /usr/share/metasploit-framework:
cd /usr/share/metasploit-framework
and after that, install bundler with gem:
gem install bundler
then:
bundle install
at the end you need to update:
gem update --system
and it will work!
This command fixes it:
apt-get install ruby2.1-dev &&\
apt-get install libsqlite3-dev &&\
bundle install
What it does: install ruby development items
