In my default folder , main.yml I have the following

percona\_version: 5.6  
percona\_pckg\_version: “{% {{percona\_version}}|replace(‘.’, ‘’) %}” # want to remove the period in 5.6 so as to get 56

The above gives error while running playbook

fatal: [x.x.x.x] =\> Failed to template {{percona\_pckg\_version}}: Failed to template {% percona\_version|replace(‘.’, ‘’) %}: template error while templating string: Encountered unknown tag ‘percona\_version’.

Any ideas?

What you want is something like:

percona\_pckg\_version: “{{ percona\_version|replace(‘.’, ‘’) }}”

You might want to read up on jinja2 a little at [http://jinja.pocoo.org/docs/dev/templates/](http://jinja.pocoo.org/docs/dev/templates/)

{% %} are used for control structures such as `for` and `if`, where as {{ }} are used to denote “expressions to print”
