kran

Deploy to Kubernetes with krane, the simple way. One command builds the image, pushes it, renders the krane templates and deploys them. A few more commands cover the daily work: logs, exec, details, audit.

gem install kran

Kran drives docker, krane and kubectl, and ejson when secrets come from krane's secrets.ejson. None of them is a gem dependency. kran version shows which ones are found.

kran init                 # writes config/kran.yml
kran deploy --dry-run     # prints every command it would run
kran deploy               # docker login, docker build --push, krane render | krane deploy
kran deploy -P            # skip the build and push
kran logs -f
kran exec bin/rails db:migrate
kran shell                # alias for: exec --interactive bash
kran console              # alias for: exec --interactive bin/rails console

Every command reads config/kran.yml. -d staging layers config/kran.staging.yml on top of it.

If you have used kamal, this will feel just as simple: familiar command names, one config file, one command to deploy.
