Ping @mbohlool .I have updated the code style for PEP8. Now, it's ready to be reviewed.

@mbohlool Updated. Plz review.

Have you actually tried this code? specially the patch that you just changed? I just want to make sure it is working for you before merging it into master. I will see if I can give it a try tomorrow.

@DjangoPeng I tried these examples and they gave me syntax errors. That could be because of the new client generation. Can you please take a look at them and make sure that they can be run?

@mbohlool I have fixed the error and tested all examples by myself. Please review and check.

@DjangoPeng The branch is out of date. The new client has some differences (like you need to provide required fields on model creation, etc.). Please rebase to master and run the examples again. An example failure I get:

ValueError: Invalid value for `template`, must not be `None`

@mbohlool Ok, I'll test it today .

I run all examples on Kubernetes 1.7 with client-python 3.0, and I attached the stdout as below. It looks like all is well. Should I try it on Kubernetes 1.8, or what?

Use master. You can goto root folder of repo and call python -m examples.deploment_examples. just make sure you rebase to the latest code.

@mbohlool Now, it works on latest master branch. I delete the rollback example because there is a error that I'm debugging and identifying. When I solve it, I'll make a new PR to append the rollback example.

@mbohlool Please review the PR. I think it's ready to be merged.

@DjangoPeng Thanks. Great work.

I have updated the description of the PR. Welcome to append the rollback example of Deployment.
