Hi @rodrigc, thanks for submitting this PR. Since our el7 rpm package is also targeting RHEL 7, will the package built with Python 3 work on RHEL 7 as well? As far as I know, RHEL 7 does not support Python 3 officially.

@fengzhou-msft from my branch with this PR, I was able to successfully build following these instructions:

https://github.com/Azure/azure-cli/blob/dev/scripts/release/rpm/README.md

docker build --target build-env -f ./scripts/release/rpm/Dockerfile.centos -t mcr.microsoft.com/azure-cli:centos7-builder .

I was then also able to successfully yum install this package in a Centos 7 environment
and run it.

If you want to double check, you can follow the instructions at to create a clean centos/7 environment: https://app.vagrantup.com/centos/boxes/7

1. Create a directory:

mkdir centos-7-clean
cd centos-7-clean

2. In this directory:

Create a file:

Vagrant.configure("2") do |config|
  config.vm.box = "centos/7"
end

3. In the same directory, create the VM:

vagrant up

4. When VM is created, log into it:

vagrant ssh

Then in that clean Centos7 environment, you can build the Centos7 azure-cli rpm package and run it.

I am running the Centos7 package built from my branch in a Centos7 environment used in my automation testing.

@fengzhou-msft for RHEL 7, RedHat has this document:
https://access.redhat.com/solutions/2353081

and this document:

https://developers.redhat.com/blog/2018/08/13/install-python3-rhel/

@rodrigc Your changes work perfectly with Cento 7. I will try to install Python 3 on RHEL 7 according to your link and see how the package works on RHEL 7.

Looks like RHEL 7.7 has support for Python 3 now : https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/7.7_release_notes/new_features#enhancement_compiler-and-tools

@fengzhou-msft thanks for accepting my patch.

One question, will Azure-cli drop support for Python 2.7? Maybe that can be done in 2020

We've planned that in S163, first release in 2020.
