Overview

Package host models a single host managed by Evergreen's application server. These hosts can be used for different purposes, such as running tasks or serving as virtual workstations.

	// MaxAgentMonitorUnresponsiveInterval is the maximum amount of time that can elapse

func IsIntentHostId 

func IsIntentHostId(id string) bool

IsIntentHostId returns whether or not the host ID is for an intent host backed by an ephemeral cloud host. This function does not work for intent hosts representing Docker containers.

func MakeContainersAndParents

func MarkInactiveStaticHosts 

func MarkInactiveStaticHosts(ctx context.Context, activeStaticHosts []string, d *distro.Distro) error

MarkInactiveStaticHosts marks static hosts in the database as terminated provided their ids aren't contained in the passed in activeStaticHosts slice. This is called in the scheduler, and marks any static host in the system that was removed from the distro as "terminated".

Previously this operation marked these hosts as "decommissioned," which is not a state that makes sense for static hosts.

If the distro is the empty string ("") then this operation affects all distros. If distro aliases are included, then this operation affects also hosts with the alias.

func MarkStaleBuildingAsFailed

NeedsAgentDeploy finds hosts which need the agent to be deployed because either they do not have an agent yet or their agents have not communicated recently.

func NeedsAgentMonitorDeploy 

func NeedsAgentMonitorDeploy(currentTime time.Time) bson.M

NeedsAgentMonitorDeploy finds hosts which do not have an agent monitor yet or which should have an agent monitor but their agent has not communicated recently.

RemoveStrict deletes a host and errors if the host is not found.

func ShCommandWithSudo 

func ShCommandWithSudo(script string, sudo bool) []string

func SyncPermanentExemptions 

func SyncPermanentExemptions(ctx context.Context, permanentlyExempt []string) error

SyncPermanentExemptions finds two sets of unexpirable hosts based on the authoritative list of permanently exempt hosts. The function returns:

  1. Hosts that are on the list of permanent exemptions but are not marked as permanently exempt (i.e. should be marked as permanently exempt).

func UnsafeReplace 

func UnsafeReplace(ctx context.Context, env evergreen.Environment, idToRemove string, toInsert *Host) error

UnsafeReplace atomically removes the host given by the idToRemove and inserts a new host toInsert. This is typically done to replace the old host with a new one. While the atomic swap is safer than doing it non-atomically, it is not sufficient to guarantee application correctness, because other threads may still be using the old host document.

func UnsetVolumeHost 

func UnsetVolumeHost(id string) error

func UpdateAll 

func UpdateAll(ctx context.Context, query bson.M, update bson.M) error

UpdateAll updates all hosts.

func UpdateOne
