make-like

An opinionated application template builder for LIKE applications

make-like is an application template builder for LIKE (Lisp In Kubernetes + Emacs) applications.

It will create the basic foundation for LIKE applications, including:

• Makefile support for
  • Running the application locally
  • Running the application as a container, managed by podman, allowing you to add additional services (postgres, etc) to the pod.
• Github Actions support for CI testing
• Smart caching of quicklisp contents in the case of container builds

The application code itself is minimal, but provides some useful foundation elements:

• Prometheus metrics support
• Support for TOML-style config.ini files for application configuration
• Git tag-based application version strings
• Sly/Slime support when run in podman-managed containers
• easy-route preconfigured with health-check and static image/js/css content routes

Tutorial

Create a likefile with contents similar to this:

(make-like:make-application
  :app-name "simple"
  :author "Anthony Green <[email protected]"
  :description "A simple sample application"

Run the make-like command:

$ make-like likefile
$ cd simple/
$ find .
.
./static
./static/js
./static/images
./static/css
./dist
./src
./src/package.lisp
./src/simple.lisp
./src/simple.asd
./README.md

./build
./build/Dockerfile.base
./build/Dockerfile
./test
./test/config.ini
./test/test.sh
./test/podman-start.sh
./test/test-pod.yml
./Makefile

The make targets look like this:

$ make
Supported targets:
 clean          - clean the source tree
 podman-start   - run in podman using test/test-pod.yml
 podman-stop    - stop the test pod
 run            - run locally

To run the application in a container, do this:

$ make podman-start
[ LOTS OF OUTPUT REDACTED ]
Waiting for http://localhost:8080/health
===========================================================================

Application: http://localhost:8080

Prometheus : http://localhost:9101/metrics

Use emacs to 'sly-connect' to localhost port 4005

Run 'make podman-stop' to stop the test pod
