PKS Harbor in action

In the previous post we introduced PKS (Pivotal Container Services) and showed a video that illustrated how easy it is to deploy by using Pivotal Ops Manager. Both the video and the post were well received but our colleagues and partners. Some of them have shown interest in the Harbor component and that is precisely what we are going to cover today. Harbor is an enterprise-class registry for Docker images. It offers improved security, high availability and performance when compared to most choices out there. Let's look at each of those in detail. SECURITY On-prem. Chances are that you are packaging your own code and even other pieces of intellectual property inside your container images for easier, faster deployment. If you do and you feel nervous about storing your container images in an online registry service like Docker Hub, let me say it, you are not the only one. As much as we all love the flexibility of cloud services, there are some risks involved and every day t

However many people started to wonder if it could be taken one step further. I like to compare Docker with VMware Workstation. It is great to create and run multiple virtual machines in my laptop but if I want those VMs to run a mission critical workload relying on a single server is not a great idea. For production I would like to see the capability to withstand hardware failures or at least to recover from them quickly. And that's why VMware has products like ESX and vCentre. We need the similar capabilities in the container world, in other words we need to manage the orchestrati
