copy files to server from relative path in ansible - ansible

Question

How can I pass a relative path so that Ansible can copy files from node/keys and copy them to a server?
The playbook is ansible/playbook.
My directory structure is:
├── ansible
│   ├── inventory
│   └── playbook
├── node
│   ├── keys
│   ├── index.js
│   ├── node_modules
│   ├── package-lock.json
│   └── utils
└── shell
├── data.json
├── create-data.sh
├── destory.sh
└── firewall-rules.sh
Below is the playbook:
- hosts: all
vars:
source: "{{ source }}"
destination: /home/ubuntu
tasks:
- name: Copy files
copy:
src: "{{ source }}"
dest: "{{ destination }}"
That's how I run:
ansible-playbook -i inventory/inventory.yaml playbook/crypto-generate.yaml
--extra-vars "source=../node/keys"
I am trying to pass a relative path.

Answer 1

I am using {{ playbook_dir }} to construct full path,see
special ansible variables
- name: Copy files
copy:
src: "{{ playbook_dir }}/../../node/keys"
dest: "{{ destination }}"

Answer 2

You can use absolute paths with src that avoids the problems of not knowing where is the root folder.
Local path to a file to copy to the remote server. This can be
absolute or relative. If path is a directory, it is copied
recursively. In this case, if path ends with "/", only inside contents
of that directory are copied to destination. Otherwise, if it does not
end with "/", the directory itself with all contents is copied. This
behavior is similar to the rsync command line tool.
