同じリモートマシン上の2つのフォルダを同期させる方法はありますか？

Question

私は次のような単純なタスクがあります。ansibleを実行している、しかし

- name: Sync /etc/spark/conf to $SPARK_HOME/conf 
    synchronize: src=/etc/spark/conf dest={{spark_home}}/conf 
    delegate_to: "{{item}}" 
    with_items: "{{play_hosts}}" 
    tags: spark 

：私はグループ内の多くのホストを持っているので

はB.をフォルダに、フォルダA内のすべてのコピーを、私は次のYAMLタスク定義を使用します-playbookは私に次のエラーを与えた：

どうやら、それは私の3つのすべてのホスト間でpermutativeのペアを作成し、すべてのペア（その9のrsyncが実行される）、どのように私は避けるん間で同期しようとしているansibleように見えますthローカルでのみrsyncを実行することができますか？

UPDATE：私はdelegate.host使用するように私のタスク定義を変更しました：

- name: Sync /etc/spark/conf to $SPARK_HOME/conf 
    synchronize: src=/etc/spark/conf dest={{spark_home}}/conf 
    delegate_to: delegate.host 
    tags: spark 

をしかし、それは明らかにansibleエンジンによって正しく解釈されていない、デバッグログは、それがで置換されていないことが明らかになりましたホストのIPアドレス：

ESTABLISH SSH CONNECTION FOR USER: None

SSH: EXEC ssh -C -q -o ControlMaster=auto -o ControlPersist=60s -o KbdInteractiveAuthentication=no -o PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey -o PasswordAuthentication=no -o ConnectTimeout=10 -o ControlPath=/home/peng/.ansible/cp/ansible-ssh-%h-%p-%r delegate.host '/bin/sh -c '"'"'(umask 77 && mkdir -p " echo $HOME/.ansible/tmp/ansible-tmp-1470667606.38-157157938048153 " && echo ansible-tmp-1470667606.38-157157938048153=" echo $HOME/.ansible/tmp/ansible-tmp-1470667606.38-157157938048153 ") && sleep 0'"'"''

これは私がansible 2.1.0.0

Answer 1

Sを使用しています、廃止予定の機能のように見えますolved：

- name: Sync /etc/spark/conf to $SPARK_HOME/conf 
    synchronize: src=/etc/spark/conf dest={{spark_home}} copy_links=true 
    delegate_to: "{{ inventory_hostname }}" 
    tags: spark 

delegate.hostは、おそらくあなたは本当のホスト名またはIPアドレスを持つ `delegate.host`を交換する必要があるように見え、新たな変数
