And as you would be building the container image again and again during development to check that your code changes are working, there's a lot of accumulated time this would save.

Then, near the end of the `Dockerfile`, we copy all the code. As this is what **changes most frequently**, we put it near the end, because almost always, anything after this step will not be able to use the cache.

```Dockerfile

     * this snapshot was created or if another edit is in progress.

    @Throws(IOException::class)
    fun edit(): Editor? = ******@****.***(key, sequenceNumber)

- The rules for incrementing `metadata.generation` of custom resources changed: ([#69059](https://github.com/kubernetes/kubernetes/pull/69059), [@caesarxuchao](https://github.com/caesarxuchao))
  - If the custom resource participates the spec/status convention, the metadata.generation of the CR increments when there is any change, except for the changes to the metadata or the changes to the status.
