  1. 1. DevOps  in  prac-ce  –   How  to  keep  focus  on   your  product?   André  Christ   Startup  Camp  Berlin,  March    2015  
  2. 2. Hint:  The  former  capital  ;-­‐)   2   Photo:  Michael  Sondermann/Bundesstadt  Bonn  
  3. 3. About   3   André  Christ   •  Co-­‐Founder  &  Co-­‐CEO   •  Responsible  for  IT  &  Finance   •  Before:  DHL,  HTGF,  Startups   LeanIX  GmbH   •  SaaS-­‐Provider  for  IT  Architecture  Mgmt   •  Self-­‐Funded,  Founded  2012  in  Bonn   •  >  20  Customers  in  US,  Europe  and  Australia    
  4. 4. What’s  your  level  of  experience  with   these  tools?   4   “Build,  ship,  and  run   distributed  applicaZons”   “Building/tesZng  soware   projects  conZnuously”   “IT  automaZon  engine  that   automates  applicaZon   deployment,  configuraZon   management,  ….”  
  5. 5. Ansible  and  Docker  clearly  connected  to  the   DevOps  “Hype”  …   5  Source:  Google  Trends   DevOps   Docker   Ansible  
  6. 6. …  while  Jenkins  is  really,  really  mature  and   widely  adopted  by  all  company  sizes   6  Source:  Google  Trends   DevOps   Docker   Ansible   Jenkins  
  7. 7. Agenda   7   Docker   Ansible   Jenkins   Mo-va-on  –  How  to  keep  focus  on  your  product?   Summary  /  Learnings  
  8. 8. Challenge  1:  Serve  high-­‐profile  customers   worldwide  with  very  limited  resources   8  
  9. 9. Challenge  2:  Scale  the  plahorm  with  the  right   tools  for  the  job   2012   2014  2013   “MVP”   SSO  &  Micro   services   Professional  Build   Process   Service-­‐  &   Quality  Ensurance   2015   Single  Page   JS  App  
  10. 10. Challenge  3:  B2B-­‐SaaS  requires  flexible   deployment  models  –  Cloud  and  On-­‐Premise     10   Different  cloud  environments   •  Amazon  Webservices  (US  &  Australia)   •  Strato  (Germany)   •  Further  providers  planned  (e.g.  Azure)   •  …   Individual  plaPorms  per  company   •  Ubuntu  Linux   •  Redhat   •  Windows   •  ….    
  11. 11. 11   Write  proper   documenta-on  and   manuals?!   Does  not  solve  our  issues*   •  High  effort  to  test   •  Not  repeatable   •  Outdated  very  soon   •  Prohibits  scale   •  Not  customer  friendly   (e.g.  on  premise)   *)  Does  not  mean  we  don’t  write  proper  documentaZon   where  needed  J  
  12. 12. ProducZon   Servers  US   ProducZon   Servers  US   Our  solu-on:  Highly  automated   build,  test  and  deploy  tool  chain   12   Develop   Build   Test   Deploy   Staging   Server   ProducZon   Servers  Europe   Developer   Machines  
  13. 13.

  15. 15. How  does  Docker  compare  to  virtual   machines?   15   Server   Host  OS   Hypervisor   Server   Host  OS   Docker  Engine   Guest  OS   Bins/Libs   App  A   Guest  OS   Bins/Libs   App  B   Svc  1   Svc  2   Bins/Libs   Virtualisa-on   Docker   Advantages   •  Significantly  faster   deployment   •  Much  less  overhead   •  Easier  migraZon   •  Faster  restart  &  cleanup   •  Fits  perfect  to  micro   services  architectures   Topics  to  be  adressed   •  IsolaZon  /  Security   •  Requires  Linux  Kernel   (Workarounds  via   boot2docker)   •  Maturity  of  tools   VM   VM   Container   Container   Svc  3   Container   Bins/Libs  
  16. 16. What  is  a  Docker  container  and  image?   16   Docker   Client   Host   Docker   Registry   Docker   Deamon   Container  1   Container  2   Container  3   Image  1   Container  N   Image  2   Image  3   Image  4   Docker  API   Private  running   stopped  
  17. 17. Simple  example:  Run  a  Database   17   Docker   Client   Host   Docker   Registry   Docker   Deamon   mydb   leanix-­‐synclog   postgres:9.4   nginx   leanix-­‐synclog   // Start a Postgres DB $ docker pull postgres:9.4 $ docker run –name mydb postgres:9.4 $ docker stop mydb // Create a new image $ docker build –-tag=“leanix/leanix- synclog” . $ docker push leanix/leanix-synclog Docker  API   …   Private  running   stopped  
  18. 18. Docker  Registry  (Docker  Hub)   18   •  100  „Official“   images   •  >  45.000  public   images   •  SubscripZon  model   for  private  images   (similar  to  GitHub)  
  19. 19. Our  example  is  cut  into  3  containers   19   DB   Synclog   REST-­‐API   Synclog  GUI   Angular.JS   Nginx  Webserver   Postgres   Java   Dropwizard   Example   Docker  Images   postgres:9.4   leanix-­‐synclog   leanix-­‐synclog-­‐client

  22. 22. How  to  Ze  everything  together?   docker-­‐compose  (was:  fig)   22   api: build: . links: - db ports: - "9100:9100” db: image: postgres docker-­‐compose.yml   $ docker-compose up $ docker-compose stop #!/bin/bash # Replace address sed -i "s/localhost:5432/ $DB_1_PORT_5432_TCP_ADDR:5432/" config.yml java -jar leanix-synclog-0.1.0.jar db migrate config.yml java -jar leanix-synclog-0.1.0.jar server config.yml leanix-­‐synclog/run.sh
