ytt-docker

A dockerfile for carvel-dev/ytt

Usage

Templating

Simply run the container and mount your files to /workspace, e.g.:

docker run --rm -v ${PWD}:/workspace gerritk/ytt -f .

Website docs

ytt originally comes with a built-in webserver that hosts the tools documentation. To be able to use it in docker however you have to pass some command line flags:

docker run --rm -p 8080:8080 gerritk/ytt website --listen-addr=0.0.0.0:8080 --redirect-to-https=false

Using an alias / function

It might be convenient to create an alias or function for the commands above. Here are a couple of examples:

1. An alias for the base templating tool:

alias ytt='docker run --rm -v ${PWD}:/workspace gerritk/ytt'

2. An alias for the website command:

alias ytt-website='docker run --rm -p 8080:8080 gerritk/ytt website --listen-addr=0.0.0.0:8080 --redirect-to-https=false'

3. A function combining both:

ytt () {
    if [ "$#" = "1" ] && [ "$1" = "website" ]; then
        docker run --rm -p 8080:8080 gerritk/ytt website --listen-addr=0.0.0.0:8080 --redirect-to-https=false
    else
        docker run --rm -v "${PWD}":/workspace gerritk/ytt "$@"
    fi
}
