[ansible-project] Re: Looping through a dictionary to create links
Well, I have a solution but it's very
https://www.goodreads.com/quotes/7053458-but-i-am-very-poorly-today-very-stupid
I've had to restructure the inventory:
all:
vars:
filesystems:
- path: /sharedfs1
links:
- src: /sharedfs1/filesets/home
dest: /home
- src: /sharedfs1/filesets/foo
dest: /opt/foo
- src: /sharedfs1/filesets/baa
dest: /opt/baa
- src: /sharedfs1/filesets/lmod
dest: /opt/lmod
- src: /sharedfs1/filesets/baz
dest: /quack/baz
- path: /sharedfs2
links:
- src: /sharedfs2/filesets/nobackup
dest: /quack/nobackup
- path: /sharefds3
- path: /sharedfs4
children:
hostlist:
hosts:
host1:
host2:
And then the playbook looks like, which does a bit more should/shouldn't
testing than initially asked for
---
- name: Create links to filesets from GPFS filesystems
hosts: all
vars:
ansible_become_user: root
ansible_become_method: sudo
tasks:
- name: Check which Spectrum Scale filesystems are mounted
stat:
path: "{{ item.path }}"
register: fsstat
loop: "{{ filesystems }}"
# It should be possible to remove this debug and use the filter directly
- name: Which filesystem mount exists?
debug:
msg: "src: {{ item.0.1.src }} dest:{{ item.0.1.dest }}"
register: linkslist
when:
- item.1.stat.exists
- item.1.stat.path == item.0.0.path
loop: "{{ filesystems|subelements('links',
skip_missing=True)|product(fsstat.results)|list }}"
- name: Stat filesystem link destinations
stat:
path: "{{ item.item.0.1.dest }}"
become: true
register: linksstat
when:
- item is not skipped
loop: "{{ linkslist.results }}"
- name: Remove link destintations (if not a link)
file:
path: "{{ item.stat.path }}"
state: absent
become: true
when:
- item is not skipped
- item.stat.isdir is defined
- item.stat.isdir
loop: "{{ linksstat.results }}"
- name: Check link destination parent directories
file:
path: "{{ item.item.0.1.dest | dirname }}"
state: directory
become: true
when:
- item is not skipped
- item.item.0.1.dest | dirname is not match("/")
loop: "{{ linkslist.results }}"
- name: Create Scale filesystem links
file:
src: "{{ item.item.0.1.src }}"
dest: "{{ item.item.0.1.dest }}"
state: link
become: true
when:
- item is not skipped

Re: [ansible-project] Send playbook output to Logstash/Elasticsearch
Late to the game, but this is the best ranked answer so far: Is there a
callback that logs _directly_ to ElasticSearch without logstash?

[ansible-project] Re: Looping through a dictionary to create links
The Python equivalent I'm trying to make is:
for sharedfs in filesystems:
if os.path.exists(sharedfs):
for link in filesystems[sharedfs]:
os.symlink(link['source']. link['target'])

[ansible-project] Looping through a dictionary to create links
Hello the list,
I have a bunch of machines with some shared file systems. Some of the file
systems are not mounted on all the machines. For the filesystems that are
mounted, I'd like to check/create a bunch of symbolic links to those
filesystems from various places in the filesystem. Some filesystems do not
have links (yet) but we may do some other things with them later.
So given a YAML inventory file:
all:
vars:
filesystems:
/sharedfs1:
- source: /sharedfs1/filesets/home
target: /home
- source: /sharedfs1/filesets/foo
target: /opt/foo
- source: /sharedfs1/filesets/baa
target: /opt/baa
- source: /sharedfs1/filesets/lmod
target: /opt/lmod
- source: /scale_wlg_persistent/filesets/baz
target: /quack/baz
/sharedfs2:
- source: /sharedfs2/filesets/scratch
target: /quack/scratch
/sharedfs3:
/sharedfs4:
children:
hostlist:
hosts:
host1:
host2:
And the following play, which checks the mount point exists
---
- name: Create links to filesets from shared filesystems
hosts: all
tasks:
- name: Check filesystems are mounted
stat:
path: "{{ item.key }}"
register: fsstat
loop: "{{ filesystems|dict2items }}"
- name: Which filesystem mount exists?
debug:
var: fsstat.stat.path
when: item.0.stat.path == item.1.key
loop: "{{ fsstat.results|product(filesystems|dict2items)|list }}"
Now what I want to do for each filesystem mount that exists, I'd like to
create a link from source to target for each list of link hashes associated
with each filesystem. Doing this in Python is almost trivial, but a massive
pain in Ansible/Jinja2
Regards,
Aaron
