Failed to build Docker image using Dockerfile in master branch

apache Airflow version

2.0.2

Environment

Configuration: Dockerfile OS (e.g. from /etc/os-release): ubuntu 16.04 Install tools: sudo docker build -t airflow-with-browser .

What happened:

I Can’t build a docker image using Dockerfile in master branch The python package dependency error occurred while building a image

The conflict is caused by:
    connexion[flask,swagger-ui] 2.6.0 depends on connexion 2.6.0 (from https://files.pythonhosted.org/packages/a7/27/d8258c073989776014d49bbc8049a9b0842aaf776f462158d8a885f8c6a2/connexion-2.6.0-py2.py3-none-any.whl#sha256=c568e579f84be808e387dcb8570bb00a536891be1318718a0dad3ba90f034191 (from https://pypi.org/simple/connexion/) (requires-python:>=3.6))
    The user requested (constraint) connexion==2.7.0

I think there a version mismatching between connexion[flask, swagger-ui] and connexion…

What you expected to happen:

Succeed to build a Airflow image

To Replicate: git clone https://github.com/apache/airflow cd airflow sudo docker build -t airflow-with-browser .

Confirmed. It works when you switch to PIP 20.2.4

docker build --build-arg AIRFLOW_VERSION="2.0.2" --build-arg AIRFLOW_PIP_VERSION=20.2.4 -t airflow-with-browser .

I will update the documentation to make it clear that you need to add the build arg when build pre-2.1 images.

I think master constraints are not refreshed recently. Let me do that now.
