Problem Statement:

• Two servers who have different username and password to connect with

Solution:

In your hosts file you can pass the variables and the different values as shown below:

• We have two hosts which we named as application-0 and application-1
• In your inventory/host file like dev/hosts, we will put details like this 

application-0 ansible_host=1.1.1.1 ansible_user="{{ app0_user}}" ansible_sudo_pass="{{ app0_pass}}" ansible_password="{{ app0_pass}}"

application-1 ansible_host=12.1.1.1 ansible_user="{{ app1_username}}" ansible_sudo_pass="{{ app1_pass}}" ansible_password="{{ app1_pass}}"

How will you pass the variable

Below is the example of how you can run the playbook using all the variables

'ansible-playbook main.yml -i inventories/${ENV}/hosts  -e "app0_user=abc" -e "app0_pass=password" -e "app1_user=abc" -e "app1_pass=password"
