Ansible best practices - how to use role/files from files directory? - ansible

Question

According to Best Practices I keep my script files in roles/X/files structure. So I have:
roles/X/files/
script.sh
library.sh
library2.sh
In roles/X/tasks/main.yml I invoke the script:
- name: Do something
script: script.sh --options
But there is sourcing of a library in the script. I wondered that only script.sh file was copied to remote_tmp/ansible-tmp-xxx/script.sh.
For each task, a file is copied to another directory (another temp directory).
Is it normal behavior? I want avoid copying files manually.
$ ansible --version
ansible 2.4.0.0
...
python version = 2.7.5 (default, Aug 4 2017, 00:39:18) [GCC 4.8.5 20150623 (Red Hat 4.8.5-16)]

My solution:
roles/X/files/test_lib.sh
#!/usr/bin/env bash
LIB="$HOME/.ansible/tmp/lib"
if [[ -f "$LIB/library.sh" ]]; then
source "$LIB/library.sh"
do_it
else
echo "ERROR library.sh not found"
fi
roles/x/files/lib/library.sh
do_it() {
echo "I'm the library"
}
roles/X/tasks/main.yml
---
- name: Creates directory
file:
path: $HOME/.ansible/tmp
state: directory
recurse: yes
- name: Check if required files exist
stat:
path: $HOME/.ansible/tmp/lib/library.sh
register: stat_lib_directory
- name: Copy library
# this copies lib from $HOME!!!
#command: cp -r lib/. $HOME/.ansible/tmp/
copy:
src: lib
dest: $HOME/.ansible/tmp
directory_mode: 0755
mode: 0644
when: stat_lib_directory.stat.exists == False
- name: Run the script on remote host
script: test_lib.sh
register: out
- debug: var=out.stdout_lines
- name: Cleaning
file:
path: $HOME/.ansible/tmp/lib
state: absent
And it finally works:
$ ansible-playbook copy-dir.yml
PLAY [host] ****************************************************************************
TASK [copy-dir : Creates directory] ****************************************************
ok: [host]
TASK [copy-dir : Check if required files exist] ****************************************
ok: [host]
TASK [copy-dir : Copy library] *********************************************************
changed: [host]
TASK [copy-dir : Run the script on remote host] ****************************************
changed: [host]
TASK [copy-dir : debug] ****************************************************************
ok: [host] => {
"out.stdout_lines": [
"\u001b[?1034hI'm the library"
]
}
TASK [copy-dir : Cleaning] *************************************************************
changed: [host]
PLAY RECAP *****************************************************************************
host : ok=6 changed=3 unreachable=0 failed=0

Just use ansible.builtin.copy and let ansible handles it for you?
https://docs.ansible.com/ansible/latest/collections/ansible/builtin/copy_module.html
Although if I have a shell script long enough that requires libraries I'd probably rewrite that in Python and even turn that into a Ansible module!

Have fun!
