CPU priority must be set appropriately on all containers.
Medium Severity
<VulnDiscussion>All containers on a Docker host share the resources equally. By using the resource management capabilities of Docker host, such as CPU shares, the user controls the host CPU resources that a container may consume. By default, CPU time is divided between containers equally. If CPU shares are not properly set, the container process may have to starve if the resources on the host are not available. If the CPU resources on the host are free, CPU shares do not place any restrictions on the CPU that the container may use.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
