Hello team,
I am trying to restart zookeeper service on all 3 nodes sequentially , we
want restart zookeeper service one by one but it will be only run on 2nd
server if 1st server zookeeper service was successful. How do i achieve
this in 1 task .
task should fail if service is not properly restarted.
- name: restart zookeeper one by one on follower first and ensure all is
good
throttle: 1
service:
name: 'confluent-zookeeper'
state: restarted
when: not zkmode.stdout_lines is search('leader')
- name: check follower zookeeper are up and running
shell: 'systemctl status confluent-zookeeper -l| grep -i error ||
systemctl status confluent-zookeeper | grep failed'
register: zkstatus
failed_when: zkstatus.rc == 0
Now in this case , 1 task is getting executed on all hosts despite having
error in logs . I want it to be failed as soon as it has error and should
not continue on next server.
