ktmpl is a tool for processing Kubernetes manifest templates. It is a very simple client-side implementation of the Templates + Parameterization proposal.
``` ktmpl 0.1.0 Produces a Kubernetes manifest from a parameterized template
USAGE: ktmpl [FLAGS] [OPTIONS] [--]
FLAGS: -h, --help Prints help information -V, --version Prints version information
OPTIONS:
-p, --parameter
ARGS: Path to the template file to be processed ```
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:
bash
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:
bash
ktmpl example.yml --parameter MONGODB_PASSWORD=password | kubectl create -f -
cargo install ktmpl
docker pull inquicker/ktmpl
git clone git@github.com:InQuicker/ktmpl.git.cargo install --path ..Make sure Cargo's bin directory is added to your PATH environment variable.
To package the current release for distribution, update TAG in the Makefile and then run make.
Release artifacts will be written to the dist directory.
Docker images for inquicker/ktmpl and inquicker/ktmpl:$TAG will be created, but you must push
them manually.
Your GPG secret key will be required to sign sha256sums.txt.
