In this blog post, i’m gonna show you, how you can use Cloudflare to access an internal pod, running on your own machine, to the outside world. All without opening any firewall ports, and with a valid certificate, and access control. And did I mention, it’s all for free. I will be doing all on the Tanzu Community edition.
Tanzu Appliation Platform (TAP) has the concept of accelerators. Accelerators contain complete and runnable application code and deployment configurations, and can be used by developers to create new projects that follow enterprise standards, as stated in the documentation. While learning TAP, I quickly saw, that a good way for me, would be to use the Carvel project YTT, to create my templates.
I have been a long time user of GitLab, due to the fact, that their runners was so easy to get working, and they allowed me to deploy them on prem, so I had access to my local enviorement. I have long been looking at Github actions, but found it hard, to combine this with local deployments (might just be me, who havent found out how).
As a part of my new role, I found myself having to manage a lot of different Kubeconfig files. Switching between 2 computers, meant it quicly became a mess, to have access to the same configs, all the time. This is my little guide on how to solve this. Note there might be a better way to do this, if you know of one, then let me know on Twitter :-)
For the last +4 years, I have had the role, of Cloud Management Specialist @ VMware. Starting 1 of november, I have been given the oppertunity, to change to our Modern Applications business unit, to focus on our Tanzu platform. Having spend the last couple of years, focusing on DevOps, and trying to understand what developers want/need, and how Operations can provide this, makes this a natural next step.
For some time, I have been writing about setting up Traefik, with docker, and using it as a reverse proxy, for my workloads. I have been running a stand alone Docker host, for a while, but due to changes in my job (more about that in the next post), I wanted to change this to Kubernetes instead, to get a lot more hands on.
Some time ago, I wrote a blog, around how to easily build and host, Docker containers using Dockers autobuild tools. After the blog post Docker both changed to using rate limits, for API calls, but also removed the Autobuild feature. I understand fully, that Docker is trying to find out, how to make money, but I am not a fan of the Rate limit.
I might be late to the party, but recently I learned about Buildpacks.io and what they can do vs Dockerfiles, and I just had to try it out. If you never heard about Buildpacks, then it’s a way to package your application into a container, without using Dockerfiles. The benefits can be
Update 7.7.2021 : There is now a patch avaliable. Please patch your systems, and only use this blog post, as a reference, on how to do configuration management, on multiple systems. And not as a way to fix this problem. https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34527 A new exploit, allowing remote code execution on Windows servers using the Print spoller service, has been released as CVE-2021-1675.
Ever since vRealize Automation 8 was released, and we started using Cloud-Init, I have been looking at installing CloudBase-Init for Windows as well, as part of my automated Packer template deployment. While Cloud-Init on Linux, is dead simple to install, the Windows version, has given me a lot of problems.
