Functions ¶

func DelResources ¶

func DelResources(ctx context.Context, client interfaces.Client, hostname string, resourceDeletes []*engine.ResDelete) (bool, error)

DelResources deletes some exported resource data from etcd. It returns an error if anything goes wrong. If it didn't need to make a changes because the data was already correct in the database, it returns (true, nil). Otherwise it returns (false, nil).

func GetResources ¶

func GetResources(ctx context.Context, client interfaces.Client, hostname string, filters []*engine.ResFilter) ([]*engine.ResOutput, error)

GetResources reads the resources sent to the input hostname, and also applies the filters to ensure we get a limited selection. XXX: We'd much rather filter server side if etcd had better filtering API's. See: https://github.com/etcd-io/etcd/issues/19667

func SetResources ¶

func SetResources(ctx context.Context, client interfaces.Client, hostname string, resourceExports []*engine.ResExport) (bool, error)

SetResources stores some resource data for export in etcd. It returns an error if anything goes wrong. If it didn't need to make a changes because the data was already correct in the database, it returns (true, nil). Otherwise it returns (false, nil).

func WatchResources ¶

func WatchResources(ctx context.Context, client interfaces.Client, hostname, kind string) (chan error, error)

WatchResources returns a channel that outputs events when exported resources change. TODO: Filter our watch (on the server side if possible) based on the collection prefixes and filters that we care about... XXX: filter based on kind as well, we don't do that currently... See: https://github.com/etcd-io/etcd/issues/19667 TODO: do the star (*) hostname matching catch-all if we have WithStar option.
