Ansible Error: template error while templating string: expected token 'end of print statement', got 'string'

kubectl get -n istio-system secret istio-ca -ogo-template='{{index .data "tls.crt"}}' | base64 -d > ca.pem

how to run the above command in an ansible playbook?

I am trying to use it as follows:

- name: Apply secret istio-ca
  shell: kubectl get -n istio-system secret istio-ca -ogo-template='{{index .data "tls.crt"}}' | base64 -d > ca.pem
  register: sout

but this gives me an error as follows:

fatal: [172.31.20.135]: FAILED! => {"msg": "template error while templating string: expected token 'end of print statement', got 'string'. String: kubectl get -n istio-system secret istio-ca -ogo-template='{{index .data \"tls.crt\"}}' | base64 -d > ca.pem"}

I swear this has been answered a thousand times, but I can't immediately find the golang/helm/kubectl specific one in the thousands of this same error

The problem is that jinja2 uses {{ as its escape syntax, but golang text templating uses {{ as its escape syntax, and because ansible does not know you mean the golang version, it tried to evaluate your go-template as if it was jinja2 and kaboom

There are two paths out of that situation: {% raw %} and {% endraw %} or having an outer jinja2 expression that resolves to the inner golang expression

- debug:
    msg: kubectl get {% raw %}-ogo-template={{ awesome }}{% endraw %}
- debug:
    msg: kubectl get -ogo-template={{"{{"}} awesome {{"}}"}}
