Transcript

1. Docker Desktop
2. Docker Desktop
3. Desktop architecture LinuxKit VM HOST Networking File Sharing Containerd Docker Engine Docker Cli Hypervisor
4. Desktop architecture with Kubernetes LinuxKit VM HOST Networking File Sharing Containerd Docker Engine Docker Cli Hypervisor Kubelet Kubernetes containers kubectl App containers
5. Docker Desktop Enterprise FOR DEVS FOR OPS Mass installation Customize default settings Mirror production to desktops Switch engine version Start docker projects in minutes Container expertise not required
6. Version Packs : select Docker & Kubernetes version
7. Switching version packs LinuxKit VM HOST Networking File Sharing Containerd Docker Engine Docker Cli Hypervisor Kubelet Kubernetes containers kubectl App containers
8. Application Designer
9. Administrator settings • Admins can choose default settings for Docker Desktop ◦ Eg. where to store VM disks, proxy settings… ◦ Also daemon settings • Some settings can be locked by admins
10. Docker Desktop versions comparison Community Enterprise Latest Docker Engine Certified Kubernetes Available for Windows 10 and macOS Install using PKG and MSI packages, easy roll-out at scale Restrict parts of configuration to administrators only Switch Docker and Kubernetes versions to match production Simplified tools for creating new Docker applications Technical Support SLA
11. How we work on Docker Desktop
12. How it is made
13. How it is made ~42k ~20k ~30k
14. Testing Docker Desktop • Unit tests specific to language ◦ Swift, golang, c#... • Desktop involves many processes ◦ Virtual machine ◦ Vpnkit, proxy running on the host ◦ Inside the VM : dockerd, kubelet • Need for End to end tests
15. The kind of end-to-end tests we do • Install Docker Desktop, start it, run docker containers • Change settings (CPU, memory allocated to the VM, change VM disk path) and restart Docker Desktop • Start Kubernetes cluster, deploy application exposing ports LinuxKit VM HOST Networking File Sharing Containerd Docker Engine Docker Cli Hypervisor Kubelet Kubernetes containers kubectl App containers
16. Some tests that are harder to automate • Desktop detects if the Hyper-V feature is enabled on Windows, and suggests to enable it if necessary • To test it : ◦ Disable Hyper-V on Windows (reboot needed) ◦ Install & start Docker Desktop, it will prompt the user to install it (requires elevation) ◦ Reboot & restart Docker Desktop
17. CI Node Virtual Machine Testing Docker Desktop in virtual machines... LinuxKit VM Networking File Sharing Containerd Docker Engine Docker Cli Hypervisor Kubelet Kubernetes containers kubectl App containers Jenkins Slave Tests … Does not work
18. Testing Windows and Mac app 9 OS versions Community + Enterprise x x 3 version packs = 54 environments Cannot use Virtual Machines Need to install specific versions of windows 10 pro & OSX Time consuming and CPU intensive
19. How it is built - solution ~100 builds triggered daily ~24k tests running daily Validation of a master commit in ~2 hours on all platforms 73 dedicated machines
21. Work in progress...
22. File sharing • Filesharing performance ◦ Raw performance ◦ Specific use cases : Develop PHP or ruby in containers is a pain • Windows ◦ Samba is often blocked (security constraints) ◦ Difficult to improve performance without changing architecture
23. What’s coming - Plugins • Ability to add features in the docker cli ◦ https://github.com/docker/app to help make Compose files more reusable and shareable. docker-app init --single-file hello ◦ Integrate docker or other external projects as plugins docker app init --single-file hello
