I have a role that I need to use for more values. For each task within the
role I register a variable: checkdeps (it's the same for all tasks within
this role - during a run it always has at least one value/output - I need
it like this because the path differs "/opt/play/apps/default-ace",
"default-device" etc.) and in the end I do an echo to view the output of
checkdeps.stdout.
Below I've put one task that will output ok and one that will intentionally
will be skipped. If I use the parameter dep: APK_PARSER in the playbook
what it does is: first checkdeps registers the output and in the second
task the value of checkdeps is replaced with nothing! Even though the task
is skipped due to no matching dep parameter.
Why does the value of checkdeps is replaced if the condition is not met ?
- name: "output ok"
shell: "cd /opt/play/apps/default-ace && play deps {{ dep }}"
register: checkdeps
when: "dep == \"APK_PARSER\""
- name: "example to skip"
shell: "cd /opt/play/apps/default-device && play deps {{ dep }}"
register: checkdeps
when: "dep == \"I\" or dep == \"II\""
- name: "echo ok if Done!"
shell: "echo \"OK - {{ dep }} Dependencies {{ checkdeps.stdout }}\""
And it gives me error:
One or more undefined variables: 'dict' object has no attribute 'stdout'
I've modified the last line without the stdout:
shell: "echo \"OK - {{ dep }} Dependencies {{ checkdeps }}\""
and it gives the output:
stdout:
OK - APK_PARSER Dependencies {u'skipped': True, u'changed': False}
did the variable checkdeps register the "skipping: [...]" ? Why it is
changing it's value if the condition is not met ?
