context

legacy Config Management tools are installing awscli-v1 even if awscli-v2 has been installed by other process

ubuntu18.04

using ubuntu:18.04 docker image

where is awscli installed if installed via pip?

installing awscliv1 with pip

root@c14afa4c9aa5:/# pip install awscli

###
### check awscli version
###
root@c14afa4c9aa5:/# aws --version
aws-cli/1.20.52 Python/3.6.9 Linux/5.10.25-linuxkit botocore/1.21.52

###
### what do the various bash builtins report (type, which, command, etc)
###
root@c14afa4c9aa5:/# type aws
aws is hashed (/usr/local/bin/aws)

root@c14afa4c9aa5:/# which aws
/usr/local/bin/aws


###
### what happens when there are other "aws" installations in different paths 
### 

root@c14afa4c9aa5:/# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

### 
### /bin/aws : create an executable thats after the real path
###
root@c14afa4c9aa5:~# touch /bin/aws && chmod 755 $_

###
### /usr/local/sbin/aws : create a file thats before the real path
###
root@c14afa4c9aa5:~# touch /usr/local/sbin/aws && chmod 755 $_

###
### /root/aws : create an executable not in real path
###
root@c14afa4c9aa5:~# touch /root/aws && chmod 755 $_

###
### show all installations (note: excutable in /root/aws not include)
###
root@c14afa4c9aa5:~# type -a aws
aws is /usr/local/sbin/aws
aws is /usr/local/bin/aws
aws is /bin/aws

What happens once the awscli-v2 is installed
