'setting correct WORKDIR in a multi-stage build for docker
I wish to build a docker image that can start a container where I can use both node version 14 and lz4. The dockerfile I have so far is:
FROM node:14-alpine
WORKDIR /app
RUN apk update
RUN apk add --upgrade lz4
node --version and lz4 --help seem to run ok with the docker run command - but I wanted to ask whether there is a specific WORKDIR I should be using in the dockerfile to follow any best practices (if any exist), or does it not matter what I set the WORKDIR to? Note I'm not sure of all my future requirements, but I may need to use this image to build other images in the future, so I want to ensure WORKDIR is set appropriately.
Solution 1:[1]
WORKDIR should be set to set the working directory for the subsequent docker commands in dockerfile, which makes things a little easy to understand as the paths will be relative to the working directory.
By default, / root dir is the set working directory. Without setting any other workdir, all the commands can have absolute paths which make it even more easy to understand.
Solution 2:[2]
It doesn't really matter much. Besides, you could always change it for your future builds.
