This commit introduces the new dcagent package. It is comprised of a
periodic process that queries the necessary endpoints to gather the
audit data and an API running on port 8325 (internal) and 8326 (admin).
The api only has one endpoint /v1/dcaudit that accepts only PATCH and
will respond with 'in-sync' or 'out-of-sync' for dcmanager-audit based
on the RegionOne data provided or will return the subcloud data for the
requested endpoints for dcorch-audit.
The agent also supports a key 'use_cache' to be sent in the payload
that will determine if it should use the cache data gathered by the
periodic process or get new information on the fly.
Example of payload using cached data:
{
"base_audit": "",
"firmware_audit": "<regionone-audit-data>",
"kubernetes_audit": "<regionone-audit-data>",
"kube_rootca_audit" : "<regionone-audit-data>",
"software_audit": "<regionone-audit-data>"
}
Example of payload requesting new information:
{
"certificates": "",
"iuser": "",
"fernet_repo": "",
"use_cache": "false"
}
NOTES:
- As patch and load audits will be deprecated in the next major
release, no effort was made to integrate both patch and load audit
to dcagent.
- All tests described below were executed applying [1] as well,
to avoid retesting.
[1]: https://review.opendev.org/c/starlingx/distcloud/+/923351
Test plan:
- PASS: Run dcmanager audit with dcagent. Verify only one call is
made to audit the subcloud and the response include the
correct sync status.
- PASS: Run dcmanager audit without dcagent. Verify the audit
works as expected querying each individual endpoint.
