Saltconf16 - Salt is Not Configuration Management
- 1. Salt is not Configuration Management (It’s So much More) Drew Malone - Devops Guy - Cloudera
- 2. pillar.get(‘speaker:bio’) Drew Malone Devops guy @ Cloudera - Internal Systems Engineering Previously - Salt the Cloud & Make it Rain! Saltstack Certified Engineer #8 @drawsmcgraw www.theReluctantTecchie.com
- 3. Why are we here? New to Salt? Overwhelmed by all the docs? ● You’re in the right place (you’re also not alone). Veteran to Salt? Want to hear how others use it? ● You’re in the right place. Tired after a long conference and just want to be done? ● It’ll be quick and I promise you’ll learn something new.
- 4. Outline 1) Config Management in a Nutshell 2) Salt Components Crash Course 3) Example Use Cases & Stories 4) Further Reading (i.e. Homework) 5) Done!
- 5. Config Management in a Nutshell Remember when…?
- 6. First day! ● Many machines ● Manual configurations ● Inconsistent results
- 7. And then…. ● More machines ● Automated configurations ● Consistent results
- 8. Finally…. ● More services ● Automated deploys ● Consistent uptime
- 9. We win! ...now what? What’s the reward for Good Work?
- 10. More Good Work ● Merge unrelated systems ● Build complex systems ● “Real Time” systems More toolsets…?

- 42. Configurations
- 46. Configurations New configs now in production!
- 47. Kerberos as a Service Salt API + Reactor = No more human error
- 48. Kerberos is Hard So is Hadoop. Kerberos AND Hadoop? We need a bigger boat.
