Host provisioning tool config
# Outline of a TOML-based DSL for configuring hosts. For now, we assume we execute these "on the box".
# Imports are processed first, and given the correct precedence as if they were passed on the command
# line. If an import uses a resolver
imports = [
"/path/to/local/something.toml",
"bucket1://some/remote.toml"
]
# Bucket is a resolver type. Configure a bucket called bucket1.

Write Golang!

Write Golang!

Go makes writing robust, powerful software easy. Write it!

Prerequesites

  • set a GOPATH and all your code lives there (echo $GOPATH)
  • make sure Go is installed with go version
  • set an alias in your shell to make it easy to hack: alias golang="cd $GOPATH/src/github.com"
