## 3. Activate ILM versioning features

This will only work with a versioned bucket, take a look at [Bucket Versioning Guide](https://docs.min.io/community/minio-object-store/administration/object-management/object-versioning.html) for more understanding.

### 3.1 Automatic removal of non current objects versions

# First Steps { #first-steps }

The simplest FastAPI file could look like this:

{* ../../docs_src/first_steps/tutorial001.py *}

Copy that to a file `main.py`.

Run the live server:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:solid">main.py</u>

  <span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting development server 🚀

						// queueing happens across namespace, ignore
						// objects that are not found.
						versionNotFound++
						continue
					}
				} else {
					// Look for the healing results
					if res.After.Drives[tracker.DiskIndex].State != madmin.DriveStateOk {
						err = fmt.Errorf("unexpected after heal state: %s", res.After.Drives[tracker.DiskIndex].State)
					}
				}

    @Resource
    private GroupPager groupPager;

    //                                                                               Hook
    //                                                                              ======

        if (host.indexOf('.') < 0 && host.toUpperCase(Locale.ROOT).equals(host)) {
            // this is not too good, probably should better pass the address and check that it is a netbios one.
            // While we could look up the domain controller/KDC we cannot really make the java kerberos implementation
            // use a KDC of our choice.

So, the interactive docs will have all the information from these dependencies too:

## Simple usage { #simple-usage }

If you look at it, *path operation functions* are declared to be used whenever a *path* and *operation* matches, and then **FastAPI** takes care of calling the function with the correct parameters, extracting the data from the request.

    protected SearchEngineClient searchEngineClient;

    // ===================================================================================
    //                                                                               Hook
    //                                                                              ======
    @Override
    protected void setupHtmlData(final ActionRuntime runtime) {
        super.setupHtmlData(runtime);

	// skip latest object from listing only for regular
	// listObjects calls, versioned based listing cannot
	// filter out between versions 'obj' cannot be truncated
	// in such a manner, so look for skipping an object only
	// for regular ListObjects() call only.
	if !o.Versioned && !o.V1 {
		fi, err := obj.fileInfo(o.Bucket)
		if err != nil {
