Ansible Automation Platform Execution Environment & tzdata

With a colleague of mine, we were testing migration of a ServiceNow – system provisioning ansible workflow from Ansible 2.9 -> Ansible Automation platform 2.x and hit an issue.

No such file or directory: '/usr/share/zoneinfo/zone.tab

My immediate thought would be that “tzdata” pkg is not installed on the UBI.

So added “tzdata” into bindep.txt and rebuild the EE image, but it didn’t work with error saying that nothing to install. (i.e. its already installed, just the file is not available, tested this with “append” in execution-environment.yml

[3/3] STEP 6/6: RUN ls -la /usr/share/zoneinfo/zone.tab
ls: cannot access '/usr/share/zoneinfo/zone.tab': No such file or directory
Error: error building at STEP "RUN ls -la /usr/share/zoneinfo/zone.tab": error while running runtime: exit status 2

To get rid of this issue, I had to just use append to “reinstall” using microdnf tzdata as below;

$ cat execution-environment.yml
---
version: 1
dependencies:
  galaxy: requirements.yml
  system: bindep.txt

additional_build_steps:
  prepend:
  append:
    - RUN microdnf reinstall -y tzdata
    - RUN ls -la /usr/share/zoneinfo/zone.tab
[3/3] STEP 6/7: RUN microdnf reinstall -y tzdata
