Why does tar say no such file or directory when extracting a file that was downloaded with wget in d-CodePudding

Building dockerfile from windows. In the settings of docker desktop it says it is using WSL backend, idk if that is useful info.

Here is the part of the dockerfile that is failing:

FROM amazon/aws-lambda-python:3.9

RUN yum install wget tar -y

RUN wget https://github.com/mozilla/geckodriver/releases/download/v0.32.0/geckodriver-v0.32.0-linux64.tar.gz
RUN ls ./
RUN tar -xzf geckodriver-v0.32.0-linux64.tar.gz

And here is the docker build output:

I've tried various directories and the ls shows the file so I am very stumped. No clue what is wrong.

CodePudding user response：

tar z tries to run gzip before it extracts the contents of the archive, and the error message is saying it can't find that tool.

It may be enough to add gzip to the list of packages you install

RUN yum install -y \
  gzip \
  tar \
  wget
