- 3. The Problem
- 4. How do I create a clean environment when I need to run a production script? How can I share that environment with other team members?
- 5. Virtual Machines Used everywhere ● VM’s are big ● They have to be patched ● Pain to move to remote sites ● Quickly get into configuration drift ● You may need to exclude the vm from the work you are trying to perform
- 6. Local Desktops Used everywhere ● They have to be patched ● Pain to move to remote sites with every change ● Quickly get out of configuration drift ● Very costly to procure and maintain
- 7. Non-Container process Create a standard image Determine your standard software stack for production scripts Install your required modules 1. Download your baseline scripts 2. Clone the VM(or image if you are still on hardware) For each breaking update, rinse and repeat
- 9. What if you could solve this horrific workflow with 3 simple commands? PUSH PULL RUN
- 10. First, Build your gold Image, then tag it.
- 11. Push Push(Upload) your image to the Docker Hub, or a private Registry.
- 12. Pull Pull (Download) the Image to a local registry for use with a docker Engine.
- 13. Run (Execute) the image to perform administrative tasks, run applications, or scripts. Run
- 14. What’s the Rub?
- 15. Pro’s ● Generally they are small and lightweight ● It’s new and exciting ● Version control is build in! ● You may get a taste of what developers go through ● You might like it! ● Clean State/Known State ● Customizeable Con’s ● It’s another thing to manage ● You need a host OS ● Customizeable (where do you begin?) ● Some things just are not there ● It’s might be new to you, SCARY! Container Pro’s and Con’s
- 16. Windows Containers Things are not as they seem ● Windows containers are HUGE, why not just use a vm? ● Any change, is a BIG change ● There is nothing to RDP to, odd ● It just doesn’t feel normal
- 18. Where did I go wrong? 1. Image size was huge, I crashed my machine. a. Creating images is an art form… just ask Abbey Fuller. b. “Creating effective Images” c. She does a great job giving you a breakdown on what not to do. Give it a watch! https://blog.docker.com/2017/04/dockercon-2017- top-rated-sessions/ 2. I’ll just install modules at runtime! Boo Ya……. a. FAIL b. SOOOOOO SLOW c. The Goal is to get the Environment up FAST! Determine if you can use Windows Server Core or if you only need Nano.
- 19. Where did I go wrong again? Ok, The modules are installed, now what? Use the built in profile script ya Dummy! People are already doing it, start with their image! Kevin Kirkpatrick (@vscripter) https://hub.docker.com/u/vscripter/ https://github.com/vScripter
- 20. Why Windows Containers? It’s what I work with all day. I’m a Windows Guy! ● Same commands ● No guess work! ● Can run Other Windows Applications And I needed a mysql plugin for Powershell to integrate with projects like XesterUI. You can in most cases use the Image that VMware provides to meet your needs. https://hub.docker.com/r/vmware/powerclicore/ ‘docker pull vmware/powerclicore’
- 21. What’s next?
- 22. Don’t Fear the Unknown! Give Docker a shot! Push, Pull, Run
- 23. I plan on using Docker images to build and deploy powershell applications in my enterprise. I’m hopeful that the VIC will soon support native Windows containers. Site 1 Site 2 Introduce a Docker Engine to each Site, you can Remotely run local commands to anything within your vSphere infrastructure and report back to a centralized repository. Push from the Primary Pull and Run from the Secondary site
