1 Deploy Stuff, Run Stuff Jax Devops London 2017 Kris

2 Kris Buytaert I used to be a Dev, Then Became an Op Chief Trolling Officer and Open Source Everything is an effing DNS Problem Building Clouds since before the bookstore Some books, some papers, some blogs Evangelizing devops Organiser of #devopsdays, #cfgmgmtcamp, #loadays,.

3 What's this devops thing anyhow?

4 Culture, automation, Measturement, sharing

5 the old days Put this Code Live, here's a tarball NOW! What dependencies? No machines available? What database? Security? High Availability? Scalability? My computer can't install this?

6 Blamefull Organisations

8 Methodologies Waterfall Watermill SAFE Scrum Kanban

9 DOD in Scrum DoD is a checklist of valuable activities required to produce software. Definition of Done is a simple list of activities (writing code, coding comments, unit testing, integration testing, release notes, design documents, etc.) that add verifiable/demonstrable value to the product. DoD is the primary reporting mechanism for team members.

10 Done means tested

11 Done means deployed In production

12 If it isn't monitored it isn't in production Done = In production and Monitored

13 A software project is not done until your last enduser is in his grave! Kris Buytaert, #devopsdays Amsterdam 2013

14 Culture, Automation, Measurement, Sharing

15 NF Requirements Non functional requirements are not part of a sprint

16 the un-buildable The libraries you depend on have been removed by the upstream author Too old Abandonned You haven't specified the versions and the 'latest' version is Broken incompatible Rubybems.org,Github.com is down

17 the un-packageable

22 the un-deployable You require manual changes to files Files in different locations Your haven't versioned all the files Plenty of files are missing Missing libraries Do you really expect everyone to know how to deploy your Flavour of the week stack

23 If my computer can't install it, the installer is broken Luke Kanies at Fosdem (2007)

24 the un-configurable Sometimes the preconfigured one Config is inside the build artifact.war, binary, code Redeploy / restart is required to reconfigure Log on with the credentials generated in /tmp/blahx2312 Click on the 3rd button on the left, then down and first on the right.

25 As a system administrator, I can tell when software vendors hate me. It shows in their products. As an Ops person DON'T make the administrative interface a GUI. System administrators need a command-line tool for constructing repeatable processes. Procedures are best documented by providing commands that we can copy and paste from the procedure document to the command line. We cannot achieve the same repeatability when the instructions are: "Checkmark the 3rd and 5th options, but not the 2nd option, then click OK." Sysadmins do not want a GUI that requires 25 clicks for each new user. Thomas A. Limoncelli in ACM Queue December

26 the un-runnable You shipped a.exe file We run on Linux You shipped a Docker file We have no containerized infrastructure Your application connects to :3306 Your application connects to myapp.ourcompany.com Your code requires Python 5 We are on EL 7

27 the un-clusterable Where is your state? How do you know where to connect to? /tmp is not a distributed filesystem

28 the un-cloudable Where is your state?

29 the un-secured Clear text passwords in config files Passwords as parameters No encryption Vague ssl version build in No authentication at all Users are stored locally

30 Culture, Automation, Measurement : measure all the things Sharing

31 the un-monitorable Is this thing even on? Logs? Log verbosity? Log corelation? Consistent output for testing If the enduser calls, your monitoring has failed

32 the un-measurable No metrics, No log entries to derive metrics from, Please provide Metrics Health / status page / api Logs

33 Culture, Automation, Measurement, Sharing

35 This new 'D' hype New kid on the block Vagrant-lxc with a nice cli The Ultimate devops tool Unseen growth Docker is the new cool thing to do

36 Docker Docker Docker Docker Docker Docker

37 A typical Enterprise Container No different from a full vm Multiple services running in one container Ssh is the default connection

38 Why? I want a VM Please fill in these 4 forms Wait 2 weeks. Repeat IT Departments have not adapted, 'Shadow'-IT is winning

39 These Days Put this Code Live, here's a Docker Container No machines available? What database? Where to store the data? Security? What distro is this even? Bad Cows? How do we monitor his? Backups? How did you build this?

40 11 days into operations Put this Code Live, here's Dockerfile What corporate proxy? Oh I missed 2 other containers Security? What distro is this even? Bad Cows? What do you mean We are a RHEL shop?

41 Closing the gaps between dev and ops, AGAIN!! Where do your containers come from? Who build it? Can you rebuild it? Do you even need a container How do you build the hosts that run the containers? Infrastructure as code ++

42 Image Build by devs, maintained by nobody

43 Can you? When GitHub is down? When rubygems.org is down? When someone removes a Node.js library? Fix critical Security Issues? Can your business surive if you answer NO to these questions?

44 It's still about collaboration I love docker as a technology I hate that it too often put us back 5 years with regards to Culture adoption Docker is an easy victim, there's other tools that create similar situations It's still mostly about Culture

45 It's not about the tools It's about change It's about the people
