Platform and service disruption avoidance using deployment metadata

A method comprising, prior to performing a maintenance activity associated with one or more nodes in a cluster:

• receiving a request to determine a state of maintenance availability of a first application of a plurality of applications installed on the cluster;
• and
• in response to receiving the request, generating a response to the request by:
• retrieving deployment metadata for the plurality of applications installed on the cluster;
• parsing the deployment metadata to identify one or more installation rules associated with the plurality of applications;
• determining that a maintenance conflict exists for the first application by analyzing the one or more installation rules, the maintenance conflict indicating that the maintenance activity associated with the one or more nodes would cause a potential disruption of the first application;
• and
• in response to determining that the maintenance conflict exists for the first application, generating the response to the request to indicate that the maintenance conflict exists for the first application, the response being usable to implement a corrective action to resolve the maintenance conflict prior to initiation of the maintenance activity.

A non-transitory computer-readable medium comprising program code that is executable by one or more processors for causing the one or more processors to, prior to performing a maintenance activity associated with one or more nodes in a cluster:

• receive a request to determine a state of maintenance availability of a first application of a plurality of applications installed on the cluster;
• and
• in response to receiving the request, generate a response to the request by:
• retrieving deployment metadata for the plurality of applications installed on the cluster;
• parsing the deployment metadata to identify one or more installation rules associated with the plurality of applications;
• determining that a maintenance conflict exists for the first application by analyzing the one or more installation rules, the maintenance conflict indicating that the maintenance activity associated with the one or more nodes would cause a potential disruption of the first application;
• and
• in response to determining that the maintenance conflict exists for the first application, generating the response to the request to indicate that the maintenance conflict exists for the first application, the response being usable to implement a corrective action to resolve the maintenance conflict prior to initiation of the maintenance activity.
