<h3 id="String_types">String types</h3>

<p>
A <i>string type</i> represents the set of string values.
A string value is a (possibly empty) sequence of bytes.
The number of bytes is called the length of the string and is never negative.
Strings are immutable: once created,
it is impossible to change the contents of a string.
The predeclared string type is <code>string</code>;

- The scheduler started considering the resource requests of existing sidecar containers during the scoring process. ([#127878](https://github.com/kubernetes/kubernetes/pull/127878), [@AxeZhan](https://github.com/AxeZhan)) [SIG Scheduling and Testing]
