That command will create or modify some [environment variables](environment-variables.md){.internal-link target=_blank} that will be available for the next commands.

One of those variables is the `PATH` variable.

/// tip

You can learn more about the `PATH` environment variable in the [Environment Variables](environment-variables.md#path-environment-variable){.internal-link target=_blank} section.

## OpenAPIとの統合

依存関係（およびサブ依存関係）のすべてのリクエスト宣言、検証、および要件は、同じOpenAPIスキーマに統合されます。

つまり、対話型ドキュメントにはこれらの依存関係から得られる全ての情報も含まれているということです:

		chains := getFilterChains(l)
		lname := "envoy://" + l.GetName()
		// Avoid duplicating the listener and filter name
		if l.GetInternalListener() != nil && len(chains) == 1 && chains[0].GetName() == lname {
			lname = "internal"
		}
		for _, fc := range chains {

			name := fc.GetName()
			matches := newMatcher(fc, l)
			destination := getFilterType(fc.GetFilters())
			for _, match := range matches {

               "datasource": {
                  "type": "prometheus",
                  "uid": "$datasource"
               },
               "expr": "pilot_total_xds_internal_errors",
               "legendFormat": "Internal Errors"
            },
            {

               },

 *  Fix: Change `MockWebServer` to use the same logic as OkHttp when determining
    whether an HTTP request permits a body.
 *  Fix: `HttpUrl` now uses the canonical form for IPv6 addresses.
 *  Fix: Use `HttpUrl` internally.
 *  Fix: Recover from Android 4.2.2 EBADF crashes.
 *  Fix: Don't crash with an `IllegalStateException` if an HTTP/2 or SPDY
    write fails, leaving the connection in an inconsistent state.
