ktmpl

ktmpl is a tool for processing Kubernetes manifest templates. It is a very simple client-side implementation of the Templates + Parameterization proposal.

Synopsis

ktmpl 0.1.0
Produces a Kubernetes manifest from a parameterized template

USAGE:
	ktmpl [FLAGS] [OPTIONS] <template> [--]

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
    -p, --parameter <parameter>...    Key-value pair used to fill in the template's parameters in the format key=value

ARGS:
    <template>    Path to the template file to be processed

Usage

Run ktmpl TEMPLATE where TEMPLATE is a path to a Kubernetes manifest template in YAML format. The included example.yml is a working example template.

To provide values for template parameters, use the --parameter option to supply key-value pairs. Using the provided example.yml, this would mean:

ktmpl example.yml --parameter MONGODB_PASSWORD=password

Template parameters that have default values can be overridden with the same mechanism.

The processed template will be output to stdout, suitable for piping into a kubectl command:

ktmpl example.yml --parameter MONGODB_PASSWORD=password | kubectl create -f -
