a10.acos_axapiで情報取得する
はじめに
A10 ACOS向けのcollectionであるa10.acos_axapiを使って、vThunderから情報取得するPlaybookの一例です。
# ansible-galaxy collection list # /root/.ansible/collections/ansible_collections Collection Version -------------- ------- a10.acos_axapi 1.0.0
SLB Server
a10_slb_serverはnameパラメータが必須です。get_type: listであれば、nameに存在しないSLB Server名を指定しても、存在するSLB Serverのリストを返してくれますが、保守性を考えると空文字等が望ましい気がします。
--- - hosts: vthunder connection: local gather_facts: no collections: - a10.acos_axapi tasks: - name: register real server a10_slb_server: name: "" state: noop get_type: list register: res_slb_server - name: debug res_slb_server debug: var: res_slb_server

VLAN
a10_network_vlanの場合はvlan_numが必須です。こちらの場合も、実在しないVLAN IDを指定しても動作し、存在するVLANの一覧を取得できます。ただし、上記のa10_slb_serverのようにvlan_num: ""と指定すると、vlan_numの値がint型を期待するため、エラーとなります。intフィルタを使うと、似たような形が実現できます。
