DevOps Days Riga 2017 talk about creating a delivery pipeline on Windows using tools like: * jenkins * ansible * powershell * chocolatey * nssm

1. Delivery Pipeline for
Windows Machines
18.09.2017 @buzdin
for fun and profit

2. Working as a consultant
• DevOps
• Test Automation
• Software Architecture (aka Microservices)
• Java Development
• Web Development (not JavaScript)

3. Continuous Delivery
Getting a code change to production in a most efficient way
(preferably automated)

5. Lets build a delivery pipeline!

7. Jenkins Pipeline
Git
checkout
Gradle
build
Run Integ
Tests
Publish to
Nexus
Deploy to
Dev
Run Func
Tests
Push to
Release
Deploy to
Staging

9. Steps to Deploy
• Generate SSH Certificate
• Provision Linux via Ansible
• Install dependencies via apt-get
• Download artefact from Artifactory via curl
• Start app as a service using systemd
• Think about switching to Docker later

10. Things to Consider
• Clustering – round-robin or
hash-based?
• Blue-green deployment
strategy?
• Should we take Kubernetes
or simply Docker Swarm?
VS

14. Mission Impossible
1. Don’t spend any money on licenses
2. Automate using familiar tools
3. You have a Mac
4. Don’t think about Docker all the time

16. Step #1 Where to get a
Windows VM?

17. Create Compute Instance

18. Create Account

19. Connect with RDP

20. Linux Windows
ansible ?
ssh ?
apt-get ?
systemd ?
docker ?

21. Ansible Core Concepts
• Works on SSH and Python
• Tasks (what to do)
• Playbook (aggregations of tasks)
• Inventory files (where to connect)
• Lots of configs, modules and plugins
• All written in YAML
https://www.ansible.com/

22. http://docs.ansible.com/ansible/list_of_windows_modules.html

23. Ansible Win Tasks
win_file
win_copy
win_service
win_uri
win_get tasks:
- name: Create a directory
win_file:
path: “C:Applogs“
state: directory
Useful commands:

24. Getting There From MacOS
$ pip install ansible
$ pip install "pywinrm>=0.2.2"

25. Windows Remote
Management Protocol
https://msdn.microsoft.com/en-us/library/aa384426(v=vs.85).aspx
“Windows Remote Management (WinRM) is the
Microsoft implementation of WS-Management
Protocol, a standard Simple Object Access Protocol
(SOAP)-based, firewall-friendly protocol that allows
hardware and operating systems, from different
vendors, to interoperate.”

26. Linux Windows
ansible ansible
ssh ?
apt-get ?
systemd ?
docker ?

27. PowerShell
https://msdn.microsoft.com/powershell

28. PowerShell

29. PowerShell Curl
https://docs.microsoft.com/en-us/powershell/module/Microsoft.PowerShell.Utility/Invoke-RestMethod?view=powershell-5.1
> Invoke-WebRequest -Uri http://my.artifactory/repo/artifact
-OutFile app.jar
$ curl http://my.artifactory/repo/artifact
--output app.jar

30. PowerShell Remoting
> Enable-PSRemoting –force
> Enter-PSSession -ComputerName 127.0.0.1 -Credential User
$ ssh user@127.0.0.1

31. Enable Ansible Remoting

32. Add Firewall Rule

33. Success!

34. PowerShell on MacOS
https://github.com/PowerShell/PowerShell/
Works on MacOS 10.12 Sierra
built on .NET Core

35. Linux Windows
ansible ansible
ssh PowerShell
apt-get ?
systemd ?
docker ?

36. $ sudo apt-get install java
VS

37. Chocolatey
https://chocolatey.org/

38. Install Package with
Chocolatey
> Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Scope
CurrentUser
> choco install jdk8 -y -params 'installdir=c:java8'
> Set-ExecutionPolicy AllSigned; iex ((New-Object
System.Net.WebClient).DownloadString('https://chocolatey.org/
install.ps1'))

39. Ansible Support
tasks:
- name: Install Java
win_chocolatey:
name: jdk8
state: present
params: "installdir=c:java8"

40. Linux Windows
ansible ansible
ssh PowerShell
apt-get Chocolatey
systemd ?
docker ?

41. $ sudo systemctl restart apache2.service
VS

42. Non-Sucking Service
Manager
https://nssm.cc/
“nssm is a service helper which doesn't suck.”

43. NSSM Usage

44. Ansible Support
tasks:
win_nssm:
name: “my_service"
application: “c:java8binjavaw.exe”
start_mode: manual
state: started
stdout_file: "{{logs_path}}stdout.log"
stderr_file: "{{logs_path}}stderr.log"
app_parameters_free_form: “{{java_opts}}"

45. DEMO TIME

47. Linux Windows
ansible ansible
ssh PowerShell
apt-get Chocolatey
systemd NSSM
docker ?

49. https://www.brianchristner.io/docker-image-base-os-size-comparison/
???
windowsservercore:latest
9426 mb
Layers: ???
~2000x

50. Nice to Know
• Possible to install Docker on Windows
• Not possible to run Windows containers and Linux
containers at the same time

51. Linux Windows
ansible ansible
ssh PowerShell
apt-get Chocolatey
systemd NSSM
docker WAT?

52. What have we learned today?

53. Same Tools, Patterns &
Practices Apply
