Fibers

Fibers are an abstraction over sequential computation, similar to threads but at a higher level. There are two ways to think about this model: by example, and abstractly from first principles. We'll start with the example.

(credit here is very much due to Fabio Labella, who's incredible Scala World talk describes these ideas far better than I can)

Callback Sequentialization

Consider the following three functions

# Reference: http://honnef.co/posts/2016/04/merging-git-repositories/

#!/bin/bash

base=baseUrl
projects=(project1 project2)
new_repo=agua

mkdir -p "$new_repo"
cd "$new_repo"

# FROM instructions support variables that are declared by any ARG instructions 
# Docker has a set of predefined ARG variables that you can use without a 
# HTTP_PROXY, HTTPS_PROXY, FTP_PROXY, NO_PROXY
ARG CODE_VERSION=latest

# Initializes a new build stage and sets the Base Image for subsequent instructions
FROM ImageName:${CODE_VERSION}

# RUN has 2 forms:
# - RUN <command> (shell form)

docker swarm init

docker swarm join-token manager

docker node ls

docker node ps node1

docker service (replace the run command)

@echo off
FOR /f "tokens=*" %%i IN ('docker ps -aq') DO docker rm %%i
FOR /f "tokens=*" %%i IN ('docker images --format "{{.ID}}"') DO docker rmi %%i
