The plays carry `any_errors_fatal: "{{ any_errors_fatal | default(true) }}"`,
added in #1201 so the behaviour could be turned off.
`any_errors_fatal` is an Ansible play keyword, and Ansible reserves keyword
names in the variable namespace. Setting it through -e, group_vars or
host_vars is rejected with "Found variable using reserved name:
any_errors_fatal" and the value never reaches the play, so the expression
always falls through to `default(true)`. The knob has been inert since it was
introduced.
Rename the variable to `kubespray_any_errors_fatal`. Default behaviour is
unchanged -- still fatal -- but `-e kubespray_any_errors_fatal=false` now
works as #1201 intended.
This matters most in playbooks/internal_facts.yml, where the fatal bootstrap
play runs ahead of the play that gathers and caches facts: one unreachable
host aborts the run before any facts are cached, the playbook still exits 0,
and a later `scale.yml --limit=...` refuses because the excluded hosts have
no cache entries. roles/network_facts already sets ignore_unreachable: true
for this reason, but it never executes.
