Role Documentation

Welcome to the “nova_status” role documentation.

Role Variables: main.yml

metadata:
  description: "Performs a release-specific readiness check before restarting services\
    \ with new code. This command expects to have complete configuration and access\
    \ to databases and services within a cell. For example, this check may query the\
    \ Nova API database and one or more cell databases. It may also make requests\
    \ to other services such as the Placement REST API via the Keystone service catalog\n\
    The nova-status upgrade check command has three standard return codes:\n0 -> All\
    \ upgrade readiness checks passed successfully and there is nothing to do. 1 ->\
    \ At least one check encountered an issue and requires further investigation.\n\
    \      This is considered a warning but the upgrade may be OK.\n2 -> There was\
    \ an upgrade status check failure that needs to be investigated.\n      This should\
    \ be considered something that stops an upgrade.\n"
