Description

This simple base Docker image containing Lapis web-framework allowing simplify creating child Docker images for project.

Usage

Your parent Docker image should be like this.

FROM tarhan/lapis:latest

In your project root where Dockerfile located create app.yml manifest structure according as in following example:

name: "yourproject"

dependencies:
  alpine:
    runtime:
      - openssl
    buildtime:
      - openssl-dev
  luarocks:    
    - luasec

Here in the example luasec package will be installed package luarocks. Luarocks tries to build package from source code so it need its headers files.
In this case luasec packages requires openssl headers files located inside openssl-dev Alpine OS package so we've specified it under dependencies.alpine.buildtime key.
Since luasec depends on openssl at runtime so we've also specified it under dependencies.alpine.runtime key.
All OS packages were been specified under dependencies.alpine.buildtime key will be removed after building your container.

Usage after building

After your container created you can use it as you used lapis command inside your project root.

Docker run

docker run --rm -it -p 8080:8080 tarhan/lapis:latest server

Result will be similar to executing following command from your project root:

lapis server

Docker Compose

Using Docker Compose you can create docker-compose.yml similar to following:

version: "2"
services:
  web:
    build: .
    command: server development
    volumes:
      - .:/app/src
      - ./logs:/usr/local/openresty/nginx/logs
    ports:
      - "8080:8080"

Mounting project folder to /app/src/ inside container provide live-reload feature during development. So you can change your code and see result without re-building project's container.
