ansible regex_replace in command - regex

Question

I'am using ansible to deploy filestore on GCP, I need to get IP from instance and use it to create mount point.
gcloud working fine but it's return bracket and simple quote with ip.
Someone can help me to remove these caractere please ? My regex command doesn't work and i'am newbie with regex.
Error tasks mount cannot resolv come from '' in ip.stdout
ansible code:
- name: get info
shell: gcloud filestore instances describe "{{nfs_id}}" --project=xxxx-xxxx --zone=xxxxx-b --format='get(networks.ipAddresses)'
register: ip
- name: master_setup.yml --> DEBUG REGEX
debug:
var: "{{ 'ip.stdout' | regex_replace('([^\\.]*)\\.(.+)$', '\\1') }}"
- name: print mount point test
debug:
msg: "{{ip.stdout}}:/{{nfs_name }}"
- name: Mount an NFS volume
mount:
fstype: nfs
state: mounted
opts: rw,sync,hard,intr
src: "{{ip.stdout}:/{{nfs_name }}"
path: /mnt/nexus-storage

Resolved doing this, it's not very sexy but it's working. If someone find a solution please forward me it.
I have used 2 regex because I don't how to remove simple quote and bracket in one line:
- name: get info
shell: gcloud filestore instances describe "{{nfs_id}}" --project=xxxx-xxxx --zone=xxxxx-b --format='get(networks.ipAddresses)' > /tmp/nfs-ip.txt
- name: sed regex to delete []
shell: sed -i 's/[][]//g' /tmp/nfs-ip.txt
- name: sed regex to delete ''
shell: sed -i 's|["'\'']||g' /tmp/nfs-ip.txt
- name: register result in var ip
shell: cat /tmp/nfs-ip.txt
register: ip
- name: Mount an NFS volume
mount:
fstype: nfs
state: mounted
opts: rw,sync,hard,intr
src: "{{ip.stdout}}:/{{nfs_name }}"
path: /mnt/nexus-storage

Q: "Cannot resolve ip.stdout"
A: The value stored in ip.stdout is a string
"ip": {
...
"stdout": "['1xx.xxx.xx.2']",
...
}
Use the filters from_yaml and first to get the first item of the list, e.g.
src: "{{ ip.stdout|from_yaml|first }}:/{{ nfs_name }}"
