I'm trying to install nvm within a Dockerfile. It seems like it installs OK, but the nvm
command is not working.
Dockerfile:
# Install nvm
RUN git clone http://github.com/creationix/nvm.git /root/.nvm;
RUN chmod -R 777 /root/.nvm/;
RUN sh /root/.nvm/install.sh;
RUN export NVM_DIR="$HOME/.nvm";
RUN echo "[[ -s $HOME/.nvm/nvm.sh ]] && . $HOME/.nvm/nvm.sh" >> $HOME/.bashrc;
RUN nvm ls-remote;
Build output:

The end of my /root/.bashrc file looks like:
[[ -s /root/.nvm/nvm.sh ]] && . /root/.nvm/nvm.sh
Everything else in the Dockerfile works. Adding the nvm stuff is what broke it. Here is the full file.
I made the following changes to your Dockerfile to make it work:
First, replace...
RUN sh /root/.nvm/install.sh;
...with:
RUN bash /root/.nvm/install.sh;
Why? On Redhat-based systems, /bin/sh
is a symlink to /bin/bash
. But on Ubuntu, /bin/sh
is a symlink to /bin/dash
. And this is what happens with dash
:
root@52d54205a137:/# bash -c '[ 1 == 1 ] && echo yes!'
yes!
root@52d54205a137:/# dash -c '[ 1 == 1 ] && echo yes!'
dash: 1: [: 1: unexpected operator
Second, replace...
RUN nvm ls-remote;
...with:
RUN bash -i -c 'nvm ls-remote';
Why? Because, the default .bashrc for a user in Ubuntu (almost at the top) contains:
# If not running interactively, don't do anything
[ -z "$PS1" ] && return
And the source-ing of nvm's scripts takes place at the bottom. So we need to make sure that bash is invoked interactively by passing the argument -i
.
Third, you could skip the following lines in your Dockerfile:
RUN export NVM_DIR="$HOME/.nvm";
RUN echo "[[ -s $HOME/.nvm/nvm.sh ]] && . $HOME/.nvm/nvm.sh" >> $HOME/.bashrc;
Why? Because bash /root/.nvm/install.sh;
will automatically do it for you:
[fedora@myhost ~]$ sudo docker run --rm -it 2a283d6e2173 tail -2 /root/.bashrc
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
Instalation of nvm on ubuntu in dockerfile
In the case of Ubuntu 20.04 you can use only these commands and everything will be alright
FROM ubuntu:20.04
RUN apt update -y && apt upgrade -y && apt install wget bash -y
RUN wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
RUN bash -i -c 'nvm ls-remote'
hopefully it will work
