Running Exiftool in Alpine Docker

Question

I have been struggling with the installation of Exiftool for my AWS ECS Container. I'm using python:3.7-alpine3.13 as my base image and successfully added exiftool and perl-image-exiftool by adding RUN apk add exiftool perl-image-exiftool to my Dockerfile.

On my Mac all I had to do was brew install exiftool to get it to work.

Although the code works in my local developement and the build process works for my container I still get the error FileNotFoundError: [Errno 2] No such file or directory: 'exiftool': 'exiftool'

Is there anything that I'm missing?

what do you get when you execute `which exiftool`? `exiftool not found` or a path? — Taxel, Jul 20 '21 at 11:57
Nothing was being returned, I found a solution by changing the line where I was installing, but I'm not sure why it made a difference... Anyway, now, when I run `which exiftool` it works — A Campos, Jul 20 '21 at 12:22
please post an answer with the `RUN` line that fixed it for future googlers arriving in this thread. — Taxel, Jul 20 '21 at 12:26

No idea why it worked or made a difference, but moving where the installation of the library was happening fixed the issue

Original

RUN apk add --update --no-cache --virtual .tmp-build-deps \
    gcc libc-dev linux-headers postgresql-dev musl-dev zlib zlib-dev \
    libressl-dev libffi-dev exiftool

Fixed

RUN apk add --update --no-cache --virtual .tmp-build-deps \
    gcc libc-dev linux-headers postgresql-dev musl-dev zlib zlib-dev \
    libressl-dev libffi-dev
RUN apk add exiftool

If anybody know why that would make a difference I would be happy to learn about it!
