template error while templating string: unexpected '.'

[cmou...@redhat.com]

Hi

How can I avoid that the template engine throws this error ?

Task

- name: Get Service Account Token
  shell: |
    /usr/local/bin/oc get sa/jenkins -n {{ namespace }} --template='{{range .secrets}}{{ .name }} {{end}}' | xargs -n 1 oc get secret --template='{{ if .data.token }}{{ .data.token }}{{end}}' | head -n 1 | base64 -D -
  register: sa_jenkins_token

Error

  fatal: [10.8.244.145]: FAILED! => {"failed": true, "msg": "template error while templating string: 
  
  unexpected '.'. String: /usr/local/bin/oc get sa/jenkins -n {{ namespace }} --template='{{range .secrets}}{{ .name }} {{end}}' | xargs -n 1 oc get secret --template='{{ if .data.token }}{{ .data.token }}{{end}}' | head -n 1 | base64 -D -"}

Regards

Charles

Don't use . in variable name.

This looks very strange and I don't understand what you are trying to do.
{{ }} is only used for variables not Jinja logic.

The shell command that I want to execute is 

oc get sa/jenkins -n infra --template='{{range .secrets}}{{ .name }} {{end}}' | xargs -n 1 oc get secret --template='{{ if .data.token }}{{ .data.token }}{{end}}' | head -n 1 | base64 -D -

and I will get as response a token

So the {{ }} characters that you see within my command are used to extract info using openshift oc template

I will change my syntax to use jsonpath

The problem is that you seem to be using templating that the `oc` command will use that overlaps with template syntax of jinja.

You will likely need to wrap your command in {% raw %}command with {{ here }}{% endraw %}

See http://jinja.pocoo.org/docs/dev/templates/#escaping

Has the same error, by trying send this way:

An unhandled exception occurred while templating 'Alertname: {{ .GroupLabels.alertname }}\n Severity: {{ .CommonLabels.severity }}\n {{ range .Alerts }}{{ .Annotations.description }}\n{{ end }}'. Error was a <class 'ansible.errors.AnsibleError'>, original message: template error while templating string: unexpected '.'. String: Alertname: {{ .GroupLabels.alertname }}\n Severity: {{ .CommonLabels.severity }}\n {{ range .Alerts }}{{ .Annotations.description }}\n{{ end }}"
}

?
Guys, make some advice, please.
