How about CI?

How about CI?

I need infrastructure!

Travis CI

• config: predefined steps
• deploy: multiple platforms
• price:
  • open source: free
  • private: 69$ (1 concurrent job)
• verdict: nice, didn't use it a lot

Semaphore

• config: predefined steps
• deploy: bunch of platforms + generic
• price:
  • open source: free
  • private: 25$ (1 concurrent job)
• verdict: works

Codeship

• config: predefined steps
• deploy: bunch of platforms + generic
• price:
  • open source: free
  • private: free (1 concurrent job, 100 builds)
  • private: 49$ (1 concurrent job, no build limit)
• verdict: slow, works, some downtime...

Circle CI 2.0

• config: Docker!
• deploy: still in development => gotta do some manual stuff
• price:
  • open source: free
  • private: free (1 concurrent job, 100 builds)
• verdict: fast, a bit more work to setup, a lot of upside (because of docker)

Punchline

• a lot of tools!
• research what fits your needs => pick
• effort:
  • infrastructure: NO
  • devops skills: limited (NO for simple things)
  • time: ~hours
• gain:
  • confidence
  • automation

?

Thanks
