ansible - example of template if else

opt1_template.j2

{# style 1 - long form #}
{% if filepath == '/var/opt/tomcat_1' %}
  {% set tomcat_value = tomcat_1_value %}
{% else %}
  {% set tomcat_value = tomcat_2_value %}
{% endif %}

{# style 2 - short form #}
{% set tomcat_value = tomcat_1_value if (filepath == '/var/opt/tomcat_1') else tomcat_2_value %}

{# style 3 - with ternary filter #}
{% set tomcat_value = (filepath == '/var/opt/tomcat_1')|ternary(tomcat_1_value, tomcat_2_value) %}

Thanks for sharing ;)

Indeed! Thank you

FYI, the set statement only needs one "=", not "==". Thanks for sharing!

Good stuff - Thank you sir!

Thank you!

thanks for sharing

Thanks . you are awesome

Thanks!

👍 Thanks again!

Amazing! Thanks for sharing

thanks!

Can the following logic be converted into the template using variables?

- name: Patch | Get the highest version number from gi_patches array
  set_fact:
    # Using expression from bms-toolkit/roles/rac-db-setup/tasks/rac-db-install.yml Line 46
    highest_version_num: "{% if not ansible_loop.first %}{% if item is version(highest_version_num, '>=') %}{{ item }}{% else %}{{ highest_version_num }}{% endif %}{% else %}{{ item }}{% endif %}"
  loop: "{{ gi_patches | json_query('[?base==`' + oracle_ver + '`].release') }}"
  loop_control:
    extended: yes
  when:
    - oracle_rel is defined
    - oracle_rel != "base"

where gi_patches is an array:

  - { category: "PSU", base: "11.2.0.4.0", release: "11.2.0.4.190416", patchnum: "29255947", patchfile: "p29255947_112040_Linux-x86-64.zip", patch_subdir: "", prereq_check: FALSE, method: "opatch auto", ocm: TRUE, upgrade: FALSE }
  - { category: "PSU", base: "11.2.0.4.0", release: "11.2.0.4.190716", patchnum: "29698727", patchfile: "p29698727_112040_Linux-x86-64.zip", patch_subdir: "", prereq_check: FALSE, method: "opatch auto", ocm: TRUE, upgrade: FALSE }

OMG :) Thank you so much

Thanks so much! <3
