I have a string variable like this RCD_APIS=backend,api-alerting,api-tracking,api-versioning
that contains the name of my docker images. I need to split it into an array and loop over it so I can pull each docker image
I have tried the with_sequence loop but i get just the index (1,2,3,..)
- name: pull images from registry
docker_image:
name: "hostname:5000/{{ RCD_APIS.split(',') }}"
pull: true
state: present
tag: "{{RCD_VERSION_CURRENT}}"
with_sequence: count={{ RCD_APIS|count }}
I also tried with_item loop but it doesn't work so i tried to debug :
vars:
- container: "{{ RCD_APIS }}"
tasks:
- name: pull images from registry debug
debug: var={{item|basename}}
with_items: container.split(',')
i get something like:
(item=container.split(',')) => {
"container.split(',')": [
"backend",
"api-alerting",
"api-tracking",
"api-versioning",
"connecteur-gdfa",
"api-batch",
"ihm"
],
"item": "container.split(',')"
}
so how can i loop over that array (like a foreach) and do the docker pull backend, docker pull api-alerting
... ?
Here you go:
- name: pull images from registry
docker_image:
name: hostname:5000/{{ item }}
pull: true
state: present
tag: "{{RCD_VERSION_CURRENT}}"
with_items: "{{ RCD_APIS.split(',') }}"
To print a list in the debug
module, where x.content
is a string with newlines, and you want to split on newlines, use:
debug:
msg: "{{ x.content.split('\n') }}"
or
debug:
var: "x.content.split('\n')"
