I need to extend a Dockerfile and add grunt
to it. I did the following:
This docker run as-is
FROM openjdk:8-jdk-slim
ARG ND=v12.13.0
RUN apt-get update && \
apt-get install --yes --no-install-recommends curl && \
NODE_H=/opt/nodejs; mkdir -p ${NODE_H} && \
curl --fail --silent --output - "http://nodejs.org/dist/${ND}/node-${ND}-linux-x64.tar.gz" \
| tar -xzv -f - -C "${NODE_H}" && \
ln -s "${NODE_H}/node-${ND}-linux-x64/bin/npm" /usr/local/bin/npm && \
ln -s "${NODE_H}/node-${ND}-linux-x64/bin/node" /usr/local/bin/node && \
ln -s "${NODE_H}/node-${ND}-linux-x64/bin/npx" /usr/local/bin/ && \
npm install grunt-cli -g
RUN grunt -v
I've put also the following which doesn't help...
ENV PATH="$PATH:/usr/local/bin"
When I run the command grunt-v
I get the following error:
/bin/sh: 1: grunt: not found
.
I try also to install grunt through npm install grunt -g
without success. Any idea how to fix it?
grunt output from docker build
/opt/nodejs/node-v12.13.0-linux-x64/bin/grunt -> /opt/nodejs/node-v12.13.0-linux-x64/lib/node_modules/grunt-cli/bin/grunt
+ grunt-cli@1.3.2
I need the grunt command to be available in this docker image
I cannot change the docker image, ie form jdk...this is given
update
I've also tried with what VonC suggested but still have issue,
FROM openjdk:8-jdk-slim
ARG ND=v12.13.0
RUN apt-get update && \
apt-get install --yes --no-install-recommends curl && \
# install node
NODE_HOME=/opt/nodejs; mkdir -p ${NODE_HOME} && \
curl --fail --silent --output - "http://nodejs.org/dist/${ND}/node-${ND}-linux-x64.tar.gz" \
| tar -xzv -f - -C "${NODE_HOME}" && \
ln -s "${NODE_HOME}/node-${ND}-linux-x64/bin/node" /usr/local/bin/node && \
ln -s "${NODE_HOME}/node-${ND}-linux-x64/bin/npm" /usr/local/bin/npm && \
ln -s "${NODE_HOME}/node-${ND}-linux-x64/bin/npx" /usr/local/bin/ && \
npm install -g grunt-cli
ENV PATH="${PATH}:/usr/local/bin"
RUN ls /usr/local/bin/
RUN grunt -v
the ls command returns
docker-java-home
node
npm
npx
Any idea what is missing?
this will work:
FROM openjdk:8-jdk-slim
ARG ND=v12.13.0
RUN apt-get update && \
apt-get install --yes --no-install-recommends curl \
&& NODE_HOME=/opt/nodejs; mkdir -p ${NODE_HOME} \
&& curl --fail --silent --output - "http://nodejs.org/dist/${ND}/node-${ND}-linux-x64.tar.gz" \
| tar -xzv -f - -C "${NODE_HOME}" \
&& ln -s "${NODE_HOME}/node-${ND}-linux-x64/bin/node" /usr/local/bin/node \
&& ln -s "${NODE_HOME}/node-${ND}-linux-x64/bin/npm" /usr/local/bin/npm \
&& ln -s "${NODE_HOME}/node-${ND}-linux-x64/bin/npx" /usr/local/bin/ \
&& npm install --prefix /usr/local/ -g grunt-cli
ENV PATH="${PATH}:/usr/local/bin"
RUN ls /usr/local/bin
RUN grunt -v
using --prefix
will tell npm to install grunt in /usr/local/bin
ls output:
Step 5/6 : RUN ls /usr/local/bin

npx
grunt -v output:
Step 6/6 : RUN grunt -v

grunt-cli: The grunt command line interface (v1.3.2)
I've put also the following which doesn't help...
ENV PATH="$PATH:/usr/local/bin"
As illustrated here , that should be enough, also the exact syntax would be (to be sure)
ENV PATH="${PATH}:/usr/local/bin"
But:
RUN grunt
RUN ls /usr/local/bin/
to see if your install command workednpm instal -g grunt
, instead of npm instal grunt -g
Another approach:
The Docker image openjdk:8-jdk-slim is based on debian:buster-slim
So try and install node through its installation script, as seen here :
# install node.js environment
RUN apt-get update && \
apt-get install -y --no-install-recommends \
gnupg && \
apt-get clean && \
rm -rf /var/lib/apt/lists/*
RUN curl -sL https://deb.nodesource.com/setup_${NODEJS_VERSION}.x | bash -
RUN apt-get update && \
apt-get install -y --no-install-recommends \
nodejs && \
apt-get clean && \
rm -rf /var/lib/apt/lists/* && \
npm install -g grunt
You can still use the same base image openjdk:8-jdk-slim
, but you just extend it with a regular node installation, rather than fiddling with symbolic links.
In your case, add ENV NODEJS_VERSION 12
first.
This works
FROM openjdk:8-jdk-slim
ARG NODE_HOME=/opt/nodejs
ARG ND=v12.13.0
ENV PATH=${PATH}:${NODE_HOME}/node-${ND}-linux-x64/bin/
RUN apt-get update && \
apt-get install --yes --no-install-recommends curl && \
# install node
mkdir -p ${NODE_HOME} && \
curl --fail --silent --output - "http://nodejs.org/dist/${ND}/node-${ND}-linux-x64.tar.gz" \
| tar -xzv -f - -C "${NODE_HOME}" && \
npm install -g grunt-cli
RUN grunt -v
First, move NODE_HOME up in your dockerfile and set it as a build arg.
That way we can already set the PATH early on.
By setting the path to the node bin folder we can use all binaries in that location without manually linking each. That translates to grunt being available after installation without additional black magic.
