Use Go templates to build config files.
- Make sure you have Go installed on your machine. https://go.dev/dl/
- Make sure that the bin directory of your GOPATH is in $PATH
export PATH=$PATH:~/go/bin
$ go install github.com/sittercity/go-cli-template@latest
Example template in app.yaml.tmpl
:
service: {{.service}}
Variables from environment:
$ export service=foo
$ go-cli-template app.yaml.tmpl
service: foo
Variables from command line:
$ go-cli-template --service=foo app.yaml.tmpl
service: foo
Override environment variables with command line:
$ export service=foo
$ go-cli-template --service=bar app.yaml.tmpl
service: bar
Template from STDIN:
$ echo 'service: {{.service}}' | go-cli-template --service=foo -
service: foo
