Question:
I am trying to set a variable in Ansible with set_fact at runtime based upon another variable. If uses first value no matter what the actual value is. Here is my code example:
|
1 2 3 4 5 |
- name: Global_vars - get date info set_fact: jm_env: "{{lookup('env', 'Environment')}}" l_env: "{% if '{{jm_env}}==Develop' %}d{% elif '{{jm_env}}==Staging'%}s{% else %}p{% endif %}" |
l_env is d no matter what jm_env is set.
Answer:
Firstly, dictionaries in YAML are not ordered (and the syntax used by Ansible here is a YAML dictionary), so you have no guarantee Ansible would first set jm_env before proceeding to l_env — you need to split the assignment into two tasks.
Secondly, your test expressions are incorrect — '{{jm_env}}==Develop' is a string because it is quoted; and testing if 'string' will always evaluate to true (this is the direct reason you always get d in the output).
Use:
|
1 2 3 4 5 6 7 8 |
- name: Set the jm_env set_fact: jm_env: "{{lookup('env', 'Environment')}}" - name: Set the l_env set_fact: l_env: "{% if jm_env=='Develop' %}d{% elif jm_env=='Staging'%}s{% else %}p{% endif %}" |
