Hello,
after hours of struggle with Ansible I've decided to ask for help smarter
people. What I'm trying to do is to remove (lets say just do ls -la for now
all files and directories within certain locations which names are not
containing any part of certain list of variables. Let me give you an
example:
- name: List currently existing letsencrypt certificates
find:
paths={{ item.paths }}
file_type={{ item.file_type }}
register: haproxy_le_existing
with_items:
- { paths: /etc/letsencrypt/live/, file_type: directory}
- { paths: /etc/haproxy/ssl/le/, file_type: file}
- debug: var='haproxy_le_ssl|map(attribute="domain")|list|join("|")'
- debug: var='haproxy_le_existing.results|sum(attribute='files',
start=[])|map(attribute='path')|map('regex_search','^((?!{{haproxy_le_ssl|
map(attribute='domain')|list|join('|')}}).)*$')| select('string') | list'
- name: Remove SSLs that are not in the config
shell: "ls -la {{ item }}"
with_items: "{{ haproxy_le_existing.results|sum(attribute='files',
start=[])|map(attribute='path')|map('regex_search','^((?!{{haproxy_le_ssl|map(attribute='domain')|list|join('|')}}).)*$')|
select('string') | list }}"
variables are here:
haproxy_le_ssl:
- { domain: let2.example.is}
- { domain: let3.example.is}
- { domain: let4.example.is}
Debug works perfectly:
TASK [common/haproxy : List currently existing letsencrypt certificates]
*******
ok: [haproxy-test.aws.example] => (item={u'file_type': u'directory', u
'paths': u'/etc/letsencrypt/live/'})
ok: [haproxy-test.aws.example] => (item={u'file_type': u'file', u'paths': u
'/etc/haproxy/ssl/le/'})
msg: All items completed
msg: All items completed
TASK [common/haproxy : debug]
**************************************************
ok: [haproxy-test.aws.example] => {
"haproxy_le_ssl|map(attribute=\"domain\")|list|join(\"|\")":
"let2.example.is|let3.example.is|let4.example.is"
}
TASK [common/haproxy : debug]
**************************************************
ok: [haproxy-test.aws.example] => {
"haproxy_le_existing.results|sum(attribute='files',
start=[])|map(attribute='path')|map('regex_search','^((?!let2.example.is|let3.example.is|let4.example.is).)*$')|
select('string') | list": [
"/etc/letsencrypt/live/let1.example.is",
"/etc/haproxy/ssl/le/dupa.pem"
]
}
most probably because it doesn't have "{{ }}", but when it comes to running
a task I've got following error:
TASK [common/haproxy : Remove SSLs that are not in the config]
*****************
fatal: [haproxy-test.aws.example]: FAILED! => {"failed": true, "msg": "template
error while templating string: expected token ',', got 'domain'. String: {{
haproxy_le_existing.results|sum(attribute='files',
start=[])|map(attribute='path')|map('regex_search','^((?!{{haproxy_le_ssl|map(attribute='domain')|list|join('|')}}).)*$')|
select('string') | list }}"}
For me creating oneliner like this is more convenient than creating
multiple tasks (most probably I could create something using join from
multiple tasks, but I'd like to understand what is happening here as using
variable inside regex seems to be quite handy and I might use it in the
future), even it is not the easiest to read way of doing the job. Please
advice what could I do in this situation.
