nodesignature computes the signature of a working set
A "working set" is a unordered set of namespaced work units running at any given time on a "node". The "signature" is a unique identifer which is bound to that specific working set. This allows to uniquely and concisely identify a workingset without enumerating all the names all the time. This concepts maps nicely on kubernetes (but is not limited to): "namespaced work units" = pods and "node" = (kubernetes) nodes.

Overview ¶
Package nodesignature computes the signature of a working set. A "working set" is a unordered set of namespaced work units running at any given time on a "node". The "signature" is a unique identifer which is bound to that specific working set. This allows to uniquely and concisely identify a workingset without enumerating - and storing - all the names all the time. This concepts maps nicely on kubernetes (but is not limited to): "namespaced work units" = pods and "node" = (kubernetes) nodes.

Constants ¶
const ( // Prefix is the string common to all the signatures // A prefix is always 4 bytes long Prefix = "nsgn" // Version is the version of this signature. You should // only compare compatible versions. // A Version is always 4 bytes long, in the form v\d\d\d Version = "v001" )
Variables ¶
var ( ErrMalformed = fmt.Errorf("malformed signature") ErrIncompatibleVersion = fmt.Errorf("incompatible version") )
