# ansible-galaxy install -r roles/install.yml -p roles

質問 2：
Create a file called specs.empty in home/bob/ansible on the local machine as follows:
HOST=
MEMORY=
BIOS=
VDA_DISK_SIZE=
VDB_DISK_SIZE=

vars:
timesync_ntp_provider: chrony
timesync_ntp_servers:
- hostname: classroom.example.com _ in exam its ip-address
iburst: yes

質問 4：
Create user accounts
------------------------
--> A list of users to be created can be found in the file called user_list.yml
which you should download from http://classroom.example.com/user_list.yml and
save to /home/admin/ansible/
--> Using the password vault created elsewhere in this exam, create a playbook called
create_user.yml
that creates user accounts as follows:
--> Users with a job description of developer should be:
--> created on managed nodes in the "dev" and "test" host groups assigned the
password from the "dev_pass"
variable and these user should be member of supplementary group "devops".
--> Users with a job description of manager should be:
--> created on managed nodes in the "prod" host group assigned the password from
the "mgr_pass" variable
and these user should be member of supplementary group "opsmgr"
--> Passwords should use the "SHA512" hash format. Your playbook should work using
the vault password file
created elsewhere in this exam.
while practising you to create these file hear. But in exam have to download as per
questation.
