hello list,

i have a strage problem.

`

# do we need to readd server to cluster in case of rebuild

- name: get etcd server  
set\_fact:  
etcd\_server: “{{ lookup(‘get\_serverip\_by\_group’, zone, ‘kubernetes\_etcd’, wantlist=True)}}”

# Get ETCD Members

- name: get all members from ETCD Cluster  
uri:  
url: http://{{ item }}:2379/v2/members  
register: etcd\_members  
with\_items: “{{ etcd\_server }}”  
when: etcd\_members is not defined or etcd\_members.failed  
ignore\_errors: true

- debug: var=etcd\_members

- name: did i get members?  
fail: msg=“NO Members found”  
when: ‘“failed” in etcd\_members.results[-1] and etcd\_members.results[-1].failed == true’

- name: body template  
template:  
src: “{{ playbook\_dir }}/templates/add\_etcd\_member.json.j2”  
dest: “{{ playbook\_dir }}/tmp/add\_etcd\_member-{{ server[‘name’] }}.json”  
when: lookup(‘get\_id\_from\_etcd\_api’, etcd\_members.results, server[‘name’]) == None

- debug: var=server

# add ETCD member

- name: add member  
uri:  
url: http://{{ item }}:2379/v2/members  
method: POST  
body\_fromat: json  
body: “{{ lookup(‘file’, playbook\_dir + ‘/tmp/add\_etcd\_member-’ + server[‘name’] \* ‘.json’) }}”  
register: etcd\_add  
with\_items: “{{ etcd\_server }}”  
when: lookup(‘get\_id\_from\_etcd\_api’, etcd\_members.results, server[‘name’]) == None  
#- (etcd\_add is not defined or etcd\_add.failed)  
ignore\_errors: true

- debug: var=etcd\_add

- name: “did i delete member: {{ server[‘name’] }}?”  
fail: msg=“did not delete {{ server[‘name’] }}”  
when: ‘“failed” in etcd\_add.results[-1] and etcd\_add.results[-1].failed == true’

`

in module template the when clause works fine, but in the URI it casues an errer

`

fatal: [localhost]: FAILED! =\> {“failed”: true, “msg”: “The conditional check ‘lookup(‘get\_id\_from\_etcd\_api’, etcd\_members.results, server[‘name’]) == None’ failed. The error was: error while evaluating conditional (lookup(‘get\_id\_from\_etcd\_api’, etcd\_members.results, server[‘name’]) == None): ‘ansible.utils.unsafe\_proxy.AnsibleUnsafeText object’ has no attribute ‘name’\n\nThe error appears to have been in ‘/build/tasks/add\_etcd\_to\_cluster.yaml’: line 35, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n # add ETCD member\n - name: add member\n ^ here\n”}

`

but i have no idea why it works the first time and not the second?

server[‘name’] is there i use it on many parts and it is working fine everywhere else.

thanks in advanced,  
mark

Seeing the output of the debug task could probably be helpful for answering your question.

hello ok

i did some more debugging.  
looks like an bug.

the combination uri, with\_items and when is the problem

using only two of them work fine

server → is a straight forward dict.
