How to execute alternatives loop (folder list) with alternatives by ansible

Question

asking for Ansible guru to help figure out. is it possible or not by Ansible

1. Jdk is downloaded and extracted to /apps/tools/jdk_1.8.121

2. binaries - /apps/tools/jdk_1.8.121/bin

needed

each binary in /apps/tools/jdk_1.8.121/bin/java, java, javadoc,

... .... and so on approximately 40 items, push to loop to alternatives programm

alternatives --install /usr/bin/java java /apps/tools/jdk_1.8.121/bin/java 1000 alternatives --install /usr/bin/{{ var }} {{var}} /apps/tools/jdk_1.8.121/bin/{{var}} 1000 

Answer 1

That's pretty easy, you just have to register the result of the find module and loop over it with with_items:

- hosts: hosts tasks: - name: Find binaries find: paths: /apps/tools/jdk_1.8.121/bin register: bins - name: Install alternatives command: "update-alternatives --install /usr/bin/{{ item.path|basename }} {{ item.path|basename }} {{ item.path }} 1000" with_items: "{{ bins.files }}" 

Or, using the alternatives module:

 - name: Install alternatives alternatives: name: "{{ item.path|basename }}" link: "/usr/bin/{{ item.path|basename }}" path: "{{ item.path }}" priority: 1000 with_items: "{{ bins.files }}" 

With Ansible 2.5 or newer, it is recommended to use loop instead of with_items:

 - name: Install alternatives alternatives: name: "{{ item.path|basename }}" link: "/usr/bin/{{ item.path|basename }}" path: "{{ item.path }}" priority: 1000 loop: "{{ bins.files|flatten(levels=1) }}"
