Hi,
I encountered a problem and cannot figure it out. I have a Ansible task to
install a web app. This web app task has a role dependency to install
tomcat while tomcat has a role dependency to install java. In the java task
I created two files under /role/java/var to define the different java
version on Solaris and Linux. I used the following code to include the yml
files under /role/java/var:
- name: Include variables for the appropriate OS family
include_vars: "{{ ansible_os_family }}.yml"
After the code above the java task will include linux.yml and solaris.yml
based on the OS:
- name: Include RedHat-specific tasks
include: RedHat.yml
when: ansible_os_family == "RedHat"
- name: Include Solaris-specific tasks
include: Solaris.yml
when: ansible_os_family == "Solaris"
Inside the RedHat.yml there are series tasks and one of those is looking
for the java version to install:
- name: Install Oracle JDK (RedHat)
yum: name="{{ item }}" state=present enablerepo=kdm
with_items: "jdkversions[ jdkversion ]['pkgs']"
register: yum_install
ignore_errors: yes
The "jdkversions" is defined in the yml file under /role/java/var.
Everything works fine if tomcat and java are installed.
If I gave a condition to the web app task not to run role dependency
"tomcat" then problem is coming: it still goes to Java task and skips all
the other tasks but "- name: Install Oracle JDK (RedHat)"; and then throws
out error complaining that "with_items expects a list or a set" because the
yml files under /role/java/var were not loaded and thus no "jdkversions"
is defined.
Can anyone please tell me the rule that which task will be skipped and
which one will not be skipped if the role dependencies are told not to
execute? I understand that Ansible will parse all tasks regardless even I
told the role dependencies not to run but if some tasks are skipped while
the others are not then how to resolve it?
Thanks in advance.
