Ansible : 명령 줄에서 역할을 실행할 수 있습니까?

Ansible : 명령 줄에서 역할을 실행할 수 있습니까?

---

"apache"라는 역할이 있다고 가정 해 보겠습니다.

이제 Ansible 호스트의 명령 줄에서 호스트 192.168.0.10에서 해당 역할을 실행하고 싶습니다.

ansible-playbook -i  "192.168.0.10" --role  "path to role"

그렇게하는 방법이 있습니까?

---

이 기능에 대해 잘 모르지만 태그를 사용하여 플레이 북에서 하나의 역할 만 실행할 수 있습니다.

roles:
    - {role: 'mysql', tags: 'mysql'}
    - {role: 'apache', tags: 'apache'}

ansible-playbook webserver.yml --tags "apache"

---

ansible 2.7을 사용하면 다음을 수행 할 수 있습니다.

$ cd /path/to/ansible/
$ ansible localhost -m include_role -a name=<role_name>
localhost | SUCCESS => {
    "changed": false,
    "include_variables": {
        "name": "<role_name>"
    }
}
localhost | SUCCESS => {
    "msg": "<role_name>"
}

이것은 / path / to / ansible / roles 또는 구성된 역할 경로에서 역할을 실행합니다.

Ansible에는 그러한 것이 없지만 이것이 자주 사용되는 경우라면이 스크립트를 사용해보십시오.
이름 아래에 검색 가능한 PATH 내 어딘가에 넣으십시오 ansible-role.

#!/bin/bash

if [[ $# < 2 ]]; then
  cat <<HELP
Wrapper script for ansible-playbook to apply single role.

Usage: $0 <host-pattern> <role-name> [ansible-playbook options]

Examples:
  $0 dest_host my_role
  $0 custom_host my_role -i 'custom_host,' -vv --check
HELP
  exit
fi

HOST_PATTERN=$1
shift
ROLE=$1
shift

echo "Trying to apply role \"$ROLE\" to host/group \"$HOST_PATTERN\"..."

export ANSIBLE_ROLES_PATH="$(pwd)/roles"
export ANSIBLE_RETRY_FILES_ENABLED="False"
ansible-playbook "$@" /dev/stdin <<END
---
- hosts: $HOST_PATTERN
  roles:
    - $ROLE
END

---

ansible-toolbox 저장소를 확인할 수도 있습니다 . 다음과 같은 것을 사용할 수 있습니다.

ansible-role --host 192.168.0.10 --gather --user centos --become my-role

---

I have written a small Ansible plugin, called auto_tags, that dynamically generates for each role in your playbook a tag of the same name. You can find it here.

After installing it (instructions are in the gist above) you could then execute a specific role with:

ansible-playbook -i "192.168.0.10" --tags "name_of_role"

---

in ansible 2.8 it works slightly different

wohlgemuth@leela:~/workspace/rtmtb-ansible/kvm-cluster$ ansible localhost -m import_role -a name=rtmtb

Have you tried that? it's super cool. I'm using 'update-os' instead of 'apache' role to give a more meaningful example. I have a role called let's say ./roles/update-os/ in my ./ I add a file called ./role-update-os.yml which looks like:

#!/usr/bin/ansible-playbook
---
- hosts: all
  gather_facts: yes
  become: yes
  roles:
  - update-os

Make this file executable (chmod +x role-update-os.yml). Now you can run and limit to whatever you have in your inventory ./update-os.yml -i inventory-dev --limit 192.168.0.10 the limit you can pass the group names as well.

• --limit web,db > web and db is the group defined in your inventory
• --limit 192.168.0.10,192.168.0.201

$ cat inventory-dev
[web]
192.168.0.10

[db]
192.168.0.201

Note that you can configure ssh-keys and sudoers policy to be able to execute without having to type password - ideal for automation, there are security implications with this. therefore you have to analyze your environment to see whether it's suitable.
