对变量使用正则

- name: Extract tomcat archive  command: chdir=/opt/software /bin/tar xvf /tmp/{
   {tomcat_bin_file}} -C /opt/software creates={
   {tomcat_bin_file|regex_replace('(.*).tar.gz$', '\\1') }

取目录中文件为变量

- name: check conf.d  shell: (cd /etc/nginx/conf.d/; find . -maxdepth 1 -type f) | cut -d'/' -f2  register: files_to_fetch  tags: fetch_nginx_conf- name: fetch conf.d  fetch: src=/etc/nginx/conf.d/{
   { item }}         dest=conf_files/nginx_conf/{
   {ansible_hostname}}_{
   {ansible_default_ipv4.address}}/conf.d/         flat=yes  with_items:  files_to_fetch.stdout_lines

指定组执行

- name: my command  command: echo stuff  when: "'groupname' not in group_names"

指定不执行

 ansible-playbook --limit 'all:!oadb01' sync_repos.yml

ip address

{
   { ansible_default_ipv4.address }}{
   { ansible_eth0.ipv4.address }}

判断目录是否挂载

- name: check if /opt/xxx is mounted or not  command: mountpoint -q /opt/xxx  register: volume_stat  failed_when: False  changed_when: False- name: debug  debug: msg="/opt/xxx is mounted"  when: volume_stat.rc == 0
