Add Dockerfile for running & self-building jscpd image

[emanuelb]

Is your feature request related to a problem? Please describe. Running software not in containers is less secure (no isolation) and less stable (software stop working due to system updates/modifications).

Describe the solution you'd like Add Dockerfile (or several) to the repo:

1. for self-building jscpd from git repo (for development)
2. for running jscpd (installation without devDependencies)

I already have Dockerfile that I use for 2 scenraio, will publish it in comment here soon, after more testing to it.

Here the Containerfile that I use on latest fedora: Build by: podman build --rm -t jscpd . Run by: podman run --name jscpd -v $(pwd):/f/:ro,Z -v jscpdreports:/home/appuser/report/ --network none --rm jscpd --reporters html,consoleFull --mode strict /f Html result is in the created volume jscpdreports (it assumed the default ./report/ is used), location of files of the volume is returned in command podman volume inspect jscpdreports it will pass the current directory to /f directory inside the container which doesn't have network access (to ensure data not leaked)

FROM docker.io/node:alpine

RUN set -ex; \
   apk update; \
   apk upgrade; \
# Runtime deps: (for 'jscpd/git blame' operation)   
   apk add --no-cache git; \
   adduser -D appuser

USER appuser
WORKDIR /home/appuser/

ENV NODE_ENV="production" 

RUN set -ex; \
    npm install --production --ignore-scripts --no-optional jscpd jscpd-badge-reporter; \
    mkdir /home/appuser/report/
    
VOLUME /home/appuser/report/

ENTRYPOINT ["/home/appuser/node_modules/jscpd/bin/jscpd"]
CMD ["--help"]

development Containerfile: (it's using COPY instruction, should be run after git clone or master.zip download)

FROM docker.io/node:alpine

RUN set -ex; \
   apk update; \
   apk upgrade; \
# Runtime deps: (for 'jscpd/git blame' operation)   
   apk add --no-cache git; \
   adduser -D appuser

USER appuser
WORKDIR /home/appuser/jscpdcode/

ENV NODE_ENV="development" 

COPY . /home/appuser/jscpdcode/

RUN set -ex; \
    npm install --development; \
    mkdir /home/appuser/report/
    
VOLUME /home/appuser/report/

ENTRYPOINT ["/home/appuser/jscpdcode/packages/jscpd/bin/jscpd"]
CMD ["--help"]

A short solution: https://github.com/hata6502/jscpd-docker

Dockerfile:

FROM node:14.15.5-alpine3.13

RUN npm install -g jscpd

WORKDIR /target
CMD jscpd
