Oh My Zsh install in docker fail - docker

I don't know why this line return 1 when I run it a docker file:
RUN sh -c "$(wget https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O -)"
I have wget install and I don't know why it's return 1 (no error message)

No idea, but you don't have to use the one step install shorthand which might give you a better idea of where the command is failing.
RUN set -uex; \
wget https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh; \
sh ./install.sh; \
rm ./install.sh

I think it's due to the interactive part of the installation script.
You should generate previously .zshrc.
RUN apt-get install -y zsh
RUN git clone https://github.com/robbyrussell/oh-my-zsh \
<installation_path>/.oh-my-zsh
COPY conf/.zshrc <installation_path>/.zshrc

when you run the following command to install oh-my-zsh, the command installed oh-my-zsh successfully and exited with code 1. (you can run echo $? to check).
sh -c "$(wget https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O -)"
echo $? #output 1
But, the docker build shell thought it's an error when commands execute without returning code 0. To solve it, we can append a zero-returned command after the install command:
RUN sh -c "$(wget https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O -)"; exit 0;

Error during installation of Node.js, node -v outputs node not found

RUN echo 'export PATH="$HOME/node-v14.17.3-linux-x64/bin:$PATH"' >> ~/.bashrc
RUN echo "The version of Node.js is $(node -v)"
All the code was right, but then I decided to add node.js installation to the Dockerfile. that begins from this line:
RUN sudo curl -L https://nodejs.org/dist/v14.17.3/node-v14.17.3-linux-x64.tar.gz --output node-v14.17.3-linux-x64.tar.gz
However, the problem right now is that I have the following error, during execution of the last line of the Dockerfile:
RUN echo "The version of Node.js is $(node -v)"
Output for this line is:
Step 10/22 : RUN echo "The version of Node.js is $(node -v)"
21:07:41 ---> Running in 863b0e75e45a
21:07:42 /bin/sh: 1: node: not found
You need to make the 2 following changed in your Dockerfile for your node installation to be included in your $PATH env var -
Remove the $HOME variable from the path you're concating, as you are currently downloading node to your root folder and not the $HOME folder -
RUN echo 'export PATH="/node-v14.17.3-linux-x64/bin:$PATH"' >> ~/.bashrc
Either source ~/.bashrc explicitly for the $PATH changes to take place or run the export command as part of the Dockerfile
Once you apply these 2 changes, the error should go away.

dockerfile how to run shopt -s extglob

I have the following Dockerfile
FROM python:3.9-slim-buster
## DO SOMETHING HERE
RUN /bin/bash -c shopt -s extglob && rm -rfv !(".env")
I am getting
Step 42/49 : RUN /bin/bash -c shopt -s extglob && rm -rfv !(".env")
---> Running in 5b4ceacb1908
/bin/sh: 1: Syntax error: "(" unexpected
HOw to run this command. I need this
Every RUN line in your Dockerfile will launch a new container with a separate shell. The extglob shell option must be set before a line of input is parsed by the shell, so one way to go about this is to launch the shell with that option enabled:
RUN /bin/bash -O extglob -c 'rm -rfv !(".env")'
The main caveat is that you have to quote the command line as a string.
I'd recommend avoiding bash-specific syntax wherever possible.
In this case, the bash-specific glob pattern !(.env) means "every file except .env. So you can accomplish this specific task by moving .env out of the way, deleting the whole directory, recreating it, and moving .env back; all without worrying about which shell expansion objects are set.
RUN cd .. \
&& mv the_dir/.env . \
&& rm -rf the_dir \
&& mkdir the_dir \
&& mv .env the_dir
You also might consider whether you need a broad rm -rf at all. Because of Docker's layer system, the previous content of the directory is still "in the image". If you use a multi-stage build then the later stage will start from a clean slate, and you can COPY in whatever you need.
FROM python:3.9-slim-buster AS build
...
FROM python:3.9-slim-buster
WORKDIR /app
COPY .env .
COPY --from=build ...
/bin/bash seems to work for "shopt -s extglob" part but not the other. Separate the lines like this:
RUN /bin/bash -c shopt -s extglob
RUN /bin/bash -c rm -rfv !(".env")
or
RUN /bin/bash -c "shopt -s extglob && rm -rfv !(\".env\")"

makefile:513: pod/perlintern.pod Segmentation fault (core dumped) When installing specific perl version in dockerfile

I am trying to install perl 5.12.3 onto a Fedora 33 Docker image in my dockerfile however when I attempt to build the image I am faced with this error:
/bin/sh: line 1: /dev/tty: No such device or address
make[1]: Leaving directory '/'
make[1]: [makefile:964: minitest] Error 1 (ignored)
./miniperl -Ilib autodoc.pl
make: *** [makefile:513: pod/perlintern.pod] Segmentation fault (core dumped)
This is how I am attempting to install it:
RUN wget https://www.cpan.org/authors/id/R/RJ/RJBS/perl-5.12.3.tar.gz
RUN tar -xzf perl-5.12.3.tar.gz
RUN perl-5.12.3/Configure -Dmksymlinks -des -Dprefix=/usr/local/ -d y &&\
make && \
make test && \
make install
RUN perl -v
I guess that the problem is that docker is running the build context with no stdin or tty. Does anyone know a fix for this? I tried to install perlbrew instead to accomplish this but that was already proving to have quite a few of its own issues. Thank you for any help or advice. I am open to any other methods to installing perl 5.12.3 in the image.
I was able to install Perl version 5.12.4 with perlbrew like this (building fedora:33 docker image from my Ubuntu 21.04 laptop):
Dockerfile:
FROM fedora:33
SHELL ["/bin/bash", "-c"]
RUN yum -y update \
&& yum -y install gcc gcc-c++ make curl \
vim wget zlib-devel openssl-devel bzip2 patch \
perl-CPAN perl-App-cpanminus
ARG user=root
ARG home=/$user
WORKDIR $home
USER $user
COPY entrypoint.sh .
RUN chmod +x entrypoint.sh
ENTRYPOINT ["./entrypoint.sh"]
entrypoint.sh:
curl -L https://install.perlbrew.pl | SHELL=/bin/bash bash
echo 'export PERLBREW_ROOT=$HOME/perl5/perlbrew' >> .bashrc
echo 'source $PERLBREW_ROOT/etc/bashrc' >> .bashrc
export PERLBREW_ROOT=$HOME/perl5/perlbrew
source $PERLBREW_ROOT/etc/bashrc
perlbrew install --notest --noman perl-5.12.4
perlbrew install-cpanm
perlbrew switch perl-5.12.4
perl --version

Ruby-Rails in Docker exits after docker run

I have created a Dockerfile based on the description to create a rails application in Linux. Currently, I have two problems with the current setting:
First, I get the error or warning after every RUN command starting with the environment variable $shell. The error looks like this:
mesg: ttyname failed: Inappropriate ioctl for device
Second, my container stops directly after starting it with
docker run -d --name rails rails:test
My current docker file looks like this:
FROM ubuntu:18.04
RUN mkdir /usr/src/rails
WORKDIR /usr/src/rails
RUN apt-get update && apt-get install -y curl gnupg
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 install -y yarn
RUN curl -sSL https://get.rvm.io | bash
RUN useradd -G rvm rails
ENV shell /bin/bash -l -c
#RUN . /usr/local/rvm/scripts/rvm
RUN echo ". /etc/profile.d/rvm.sh" >> ~/.bashrc
RUN $shell "rvm requirements"
RUN $shell "rvm install ruby"
RUN echo "gem: --no-rdoc --no-ri" >> ~/.gemrc
RUN $shell "gem install rails"
RUN $shell "ruby -v" && $shell "rails -v"
USER rails
EXPOSE 3000
#CMD ["rails", "server", "-b", "0.0.0.0"]
CMD ["/bin/bash"]
The solution with the $shell variable I found on another website. Without the command /bin/bash -l -c the build process will fail. The command rvm or gem will be unknown. The mentioned command will be used as a wrapper around the real command inside the quotes. I do not really understand why this is necessary. If I create a docker container and execute the commands like they are in the Dockerfile, then everything works fine. Why it is not working as I execute the command inside of the Dockerfile script?
Since I use the wrapper command, everything works well, but I get this error or warning message mentioned above. The image will be made, so this is more like a minor problem. The main problem is, that my container doesn't start. If I type the command docker run -d rails:test the container will be exited directly after. I do not really understand why. Does anyone have some explanations?

Dockerfile hide output of RUN command

If I have a few RUN commands in my Dockerfile, how can I have it not print any output from a specific command, such as ignoring the printed statements from an apt-get update?
This works for me
FROM ubuntu:16.04
RUN which nano || echo no nano
RUN bash -c "apt-get update &> /dev/null"
RUN bash -c "apt-get install nano &> /dev/null"
RUN which nano
(really got the solution from Redirecting command output in docker)
