About

I created these Docker containers to have disposable container for given V versions. I plan to follow V version, as well as each version after the v1 release, so you can choose your containers given the V version and OS of your choice.

Features

• Provides containers for specific V version
• Provide containers that is always up to date with the latest changes (master branch) of the V Github repository
• Provide containers for Alpine Linux, Ubuntu and Debian

Examples

• 1. Using Docker Compose
• 2. Avoid loosing v package using Docker Compose

1. Using Docker Compose

In this example, we will create a container that contains the v executable on Alpine Linux OS.

version: "3"
services:
  v:
    image: khalyomede/vlang:latest-alpine
    entrypoint: v
    volumes:
      - .:/home/alpine
    working_dir: /home/alpine

Then, startup your containers:

$ docker-compose up --dettach

Finally, check v is executable:

$ docker-compose run v --version
V 0.2.2 f4486d7

2. Avoid loosing v package using Docker Compose

V manages modules on a OS wide folder (like Python), under /root/.vmodules (on Linux based OS). In this example, we will mount this folder in our project to keep installed modules.

version: "3"
services:
  v:
    image: khalyomede/vlang:latest-alpine
    entrypoint: v
    volumes:
      - .:/home/alpine
      - ./docker-data/v/root/.vmodules:/root/.vmodules
    working_dir: /home/alpine

This will create a new docker-data/v/root/.vmodules folder in your working folder.

Avaialble containers

OS	Tag
Alpine 3.13.5	khalyomede/vlang:latest-alpine
Ubuntu 20.04	khalyomede/vlang:latest-ubuntu
Debian 9 (Slim)	khalyomede/vlang:latest-debian

Test

Compile the images

docker build --no-cache latest-alpine -t khalyomede/vlang:latest-alpine
docker build --no-cache latest-ubuntu -t khalyomede/vlang:latest-ubuntu
docker build --no-cache latest-debian -t khalyomede/vlang:latest-debian

Create a docker-compose.yml file

version: "3"
services:
  v:
    build: ./latest-alpine
    entrypoint: v
    volumes:
      - .:/home/alpine
    working_dir: /home/alpine

Create an index.v file

fn main() {
  println("hello world")
}

Startup your container and test

$ docker-compose run v run index.v
hello world
