How can I change the path for specific host

Hi all,

I have to copy a file into a directory to specific hosts, but the path changes for specific hosts.

Ex.:

Inventory:

[webserver]
hosta
hostb

task: Copy a file into:

hosta: /usr/app/abc/dir
hostb: /usr/app/def/dir

But, I don’t know how to use those variables in the “same task” using “webserver” as target.

thank you,
Guilherme.

If they're in different groups, make the path a group var.
If they're in the same groups, make the path a host var.

Hi Dick,

Thank you for your attention, but what you mean when you says “host var”?

INVENTORY:
[webserver]

hosta

hostb

TASK1:

  • name: copy script to server A

copy: src=jboss.sh dest=/usr/app/abc/dir mode=u+rwx

TASK2:

  • name: copy script to server B
    copy: src=jboss.sh dest=/usr/app/def/dir mode=u+rwx

COMMAND:

ansible-playbook -i inventory environment --limit webserver

The destination is different on both hosts and I can’t reduce those tasks to only one, because of subdirectories “abc” and “def”.

Thank you again,
Guilherme.

You can use host vars or group vars like the following.

In the root of your ansible repo where your inventory file sits create the following yaml files for host vars

host_vars/hosta
host_vars/hostb

Within these files you can now specify variables e.g within host_vars/hosta

file_path: /file/path/for/hosta

And then create file host_vars/hostb

file_path: /file/path/for/hostb

Within your playbook you can now specify

TASK1:

  • name: copy script to server A

copy: src=jboss.sh dest=“{{ file_path }}” mode=u+rwx

This will use the variable from within your host_vars file, its the same for group vars only the folder is called group_vars and you would instead use the group names instead of the host names.

Kind Regards

Hi Greg, I’ve just created the vars as you said and it worked, thank you very much!
