What happened:
Hi, when execute the command docker build -t ritchie-cli . in root directory I receive the error: "ERROR: unsatisfiable constraints"

What you expected to happen:
Generate a docker image for build and run application

How to reproduce it (as minimally and precisely as possible):
In root directory the project run the command docker build .

Anything else we need to know?:
My objective is using the Dockerfile for build and run the application. I using the VScode, and is my plan use the .devcontainer feature for contribute the project.

Environment:

For solution this problem is possible to change the Dockerfile from python to python3.
But in command run is explicit the removing cache from python2.7.
What the version is necessary for project?
When the project call the python?

RUN apk update && apk add \
    alpine-sdk \
    gettext \
    curl \
    python3 \
    py-pip \
    jq \
    git \
    && pip install --no-cache-dir awscli==1.16.310 \
    && apk del py-pip \
    && rm -rf /var/cache/apk/* /root/.cache/pip/* /usr/lib/python2.7/site-packages/awscli/examples
