Role fails in Ansible Check mode #548
Description
Bug Overview
Role fails when run in check mode on ansible 2.16+
Expected Behavior
When I run the playbook in check mode all the roles should function correctly and check things without creating resources
Steps to Reproduce the Bug
- I have deployed/run the NGINX config Ansible role using the following
playbook.yml...
- role: nginxinc.nginx
become: true
vars:
nginx_type: "opensource"
nginx_manage_repo: false
nginx_branch: stable
nginx_setup_license: false
nginx_modules:
- geoip
nginx_logrorate_conf_enable: true
# configure nginx using the official nginx role
- role: nginxinc.nginx_config
become: true
vars:
nginx_config_start: true
nginx_config_debug_output: true
# don't try to upload TLS certificates, that's handled by cert-manager
nginx_config_upload_ssl_enable: false
nginx_config_cleanup: false
nginx_config_cleanup_paths:
- directory:
- /etc/nginx/conf.d
recurse: false
nginx_config_cleanup_files:
- /etc/nginx/conf.d/default.conf
# replace the default config file with one from the template
nginx_config_main_template_enable: true
# could be www-data
nginx_config_user: www-data
# the rest of the config is irrelevant since the error is not related to the configuration of nginx
- I have seen the following error(s) on my terminal/logs...
