August 16th, 2016 4 comments

The VMworld 2016 is coming in about two weeks. Although I’ve attended every single VMworld after 2007, it’s my first time as an exhibitor myself, to be exact, as a new innovator in the show. If you follow my blog and Twitter, you probably have know the company DoubleCloud that I had founded and the cool products/technologies we’ve been working on. This is the first year for us to promote our products in show. Please come to see our product demos, or simply stop by and say hi. Our booth is 841#4.

How to Install Kubernetes to Run Docker on VMware vSphere

June 6th, 2016 1 comment

Installing Google Kubernetes does not require VMware vSphere or any other virtual machine hypervisor. However, doing that on a VM is very convenient, so it’s highly recommended especially for development and testing environment.

Simple Script to List and Remove All Stopped Docker Containers

May 27th, 2015 6 comments

While using Docker command lines, I found it’s sometime a bit confusing to deal with containers. For the underlying operating system, a container is like a process. That is why the docker command use “ps” as the command to list these commands.

However, the typical “ps” command lists all the running processes. When a process dies, it is gone and there is no need to list it at all. For the containers, the story is different. The container can also be stopped, paused, which is different from running state. But you can still bring them back to running state later.
