We are going to start from where we left in the previous chapter and increment it.

## About JWT

JWT means "JSON Web Tokens".

It's a standard to codify a JSON object in a long dense string without spaces. It looks like this:

```
eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c
```

			goto scan
		default:
			err = d.mkError(ErrSyntax, "after object key:value pair")
			goto out
		}
	}

out:
	d.depth--
	return obj, err
}

// returns the next char after white spaces
func (d *Decoder) skipSpaces() byte {
	for d.pos < atomic.LoadInt64(&d.end) {
		switch c := d.next(); c {
		case '\n':
			d.lineStart = d.pos
			d.lineNo++
			continue
		case ' ', '\t', '\r':

  @AndroidIncompatible // Android forbids null parent ClassLoader
  // https://github.com/google/guava/issues/2152
  public void testJarFileWithSpaces() throws Exception {
    URL url = makeJarUrlWithName("To test unescaped spaces in jar file name.jar");
    URLClassLoader classloader = new URLClassLoader(new URL[] {url}, null);
    assertThat(ClassPath.from(classloader).getTopLevelClasses()).isNotEmpty();
  }

### Kubernetes Node system swap support

Every system administrator or Kubernetes user has been in the same boat regarding setting up and using Kubernetes: disable swap space. With the release of Kubernetes 1.22, *alpha* support is available to run nodes with swap memory. This change lets administrators opt in to configuring swap on Linux nodes, treating a portion of block storage as additional virtual memory.

### General ephemeral volumes

        assertEquals("3", extractData.getValues("meta:character-count")[0]);
        assertEquals("じょうたい", extractData.getValues("cp:contentStatus")[0]);
        assertEquals("3", extractData.getValues("meta:character-count-with-spaces")[0]);
        assertEquals("たいとる", extractData.getValues("dc:title")[0]);
        assertEquals("2", extractData.getValues("extended-properties:TotalTime")[0]);

    for each. This changes `Address` to no longer use `ConnectionSpec`. (This is
    an incompatible API change).

 *  **`FormEncodingBuilder` now uses `%20` instead of `+` for encoded spaces.**
    Both are permitted-by-spec, but `%20` requires fewer special cases.

 *  **Okio has been updated to 1.4.0.**
     ```xml
     <dependency>
       <groupId>com.squareup.okio</groupId>

6. Set the **command** to use `fastapi run`, which uses Uvicorn underneath.

    `CMD` takes a list of strings, each of these strings is what you would type in the command line separated by spaces.

    This command will be run from the **current working directory**, the same `/code` directory you set above with `WORKDIR /code`.
