Hey, I’ve been using Codeship for my own CI/cd of serverless (ended up working there 
but haven’t moved to the encrypted variables yet.
Just wanted to let you know that there’s a free tier for the pro version of Codeship as well in case you want to try it out. Keep in mind that you don’t need to deploy containers to use Pro; as long as you can define your environment using docker files, you’ll be fine
