Moto. AWSni masxara qilish

Sinov ishlab chiqish jarayonining ajralmas qismidir. Va ba'zida ishlab chiquvchilar o'zgarishlarni amalga oshirishdan oldin mahalliy testlarni o'tkazishlari kerak.
Agar ilova ishlatilsa Amazon veb-xizmatlari, python kutubxona moto bu uchun mukammal.


Resurs qamrovining to'liq ro'yxatini ko'rish mumkin shu yerda.
Githubda sholg'om bor Hugo Pikado - moto-server. Tayyor rasm, ishga tushirish va foydalanish. Faqatgina nuance - ishga tushirilgandan keyin, yo'q AWS u yerda hali resurslar yaratilmagan.

Xo'sh, buni tuzatish juda oson.

Boshlashda siz xizmat turini ko'rsatishingiz kerak (taxminan o'zgaruvchan MOTO_SERVICE), biz faqat resurs yaratilishini tasvirlashimiz kerak.

Keling, biroz o'zgartiraylik boshlash.sh:

Buning o'rniga

moto_server $MOTO_SERVICE -H $MOTO_HOST -p $MOTO_PORT

Kiritmoq:

if [ -f /opt/init/bootstrap.py ]; then
  moto_server $MOTO_SERVICE -H $MOTO_HOST -p $MOTO_PORT & (sleep 5 && echo "Executing bootstrap script." && python /opt/init/bootstrap.py)
else
  moto_server $MOTO_SERVICE -H $MOTO_HOST -p $MOTO_PORT
fi
wait

Yakuniy fayl:

boshlash.sh

#!/bin/sh

# validate required input
if [ -z "$MOTO_SERVICE" ]; then
  echo "Please define AWS service to run with Moto Server (e.g. s3, ec2, etc)"
  exit 1
fi

# setting defaults for optional input
if [ -z "$MOTO_HOST" ]; then
  MOTO_HOST="0.0.0.0"
fi

if [ -z "$MOTO_PORT" ]; then
  MOTO_PORT="5000"
fi

echo "Starting service $MOTO_SERVICE at $MOTO_HOST:$MOTO_PORT"

if [ -f /opt/init/bootstrap.py ]; then
  moto_server $MOTO_SERVICE -H $MOTO_HOST -p $MOTO_PORT & (sleep 5 && echo "Executing bootstrap script." && python /opt/init/bootstrap.py)
else
  moto_server $MOTO_SERVICE -H $MOTO_HOST -p $MOTO_PORT
fi
# Prevent container from exiting when bootstrap.py finishing
wait

Biz yangi rasm yaratamiz va uni reestrimizga joylashtiramiz.

Keyinchalik, masalan, resursni ishga tushirish skriptini yozamiz SWF domeni, AWS - boto3 bilan ishlash uchun kutubxonadan foydalanish:

bootstrap_swf.py

import boto3
from botocore.exceptions import ClientError
import os

os.environ["AWS_ACCESS_KEY_ID"] = "fake"
os.environ["AWS_SECRET_ACCESS_KEY"] = "fake"

client = boto3.client('swf', region_name='us-west-2', endpoint_url='http://localhost:5000')

try:
    client.register_domain(
        name='test-swf-mock-domain',
        description="Test SWF domain",
        workflowExecutionRetentionPeriodInDays="10"
    )
except ClientError as e:
    print "Domain already exists: ", e.response.get("Error", {}).get("Code")

response = client.list_domains(
    registrationStatus='REGISTERED',
    maximumPageSize=123,
    reverseOrder=True|False
)

print 'Ready'

Mantiq shunday:

• Boshlashda biz skriptimizni o'rnatamiz /opt/init/bootstrap.py.
• Agar fayl o'rnatilgan bo'lsa, u bajariladi.
• Agar fayl bo'lmasa, yalang'och moto-server shunchaki ishga tushadi.

Va siz bitta konteynerni ishga tushirish orqali butun resursni masxara qilishingiz mumkin:

docker run --name swf -d 
    -e MOTO_SERVICE=swf 
    -e MOTO_HOST=0.0.0.0 
    -e MOTO_PORT=5000 
    -p 5001:5000 
    -v /tmp/bootstrap_swf.py:/opt/init/bootstrap.py 
    -i awesome-repo.com/moto-server:latest

Keling, interaktiv tarzda sinab ko'raylik:

U ishlaydi!

Shunday qilib, biz docker-compose.yml ni yaratishimiz mumkin, bu test o'zgarishlarini vaqtni tejaydi:

docker-compose.yml

version: '3'
services:
  s3:
    image: picadoh/motocker
    environment:
      - MOTO_SERVICE=s3
      - MOTO_HOST=10.0.1.2
    ports:
      - "5002:5000"
    networks:
      motonet:
        ipv4_address: 10.0.1.2
    volumes:
      - /tmp/bootstrap_s3.py:/opt/init/bootstrap.py
  swf:
    image: picadoh/motocker
    environment:
      - MOTO_SERVICE=swf
      - MOTO_HOST=10.0.1.3
    ports:
      - "5001:5000"
    networks:
      motonet:
        ipv4_address: 10.0.1.3
    volumes:
      - /tmp/bootstrap_swf.py:/opt/init/bootstrap.py
  ec2:
    image: picadoh/motocker
    environment:
      - MOTO_SERVICE=ec2
      - MOTO_HOST=10.0.1.4
    ports:
      - "5003:5000"
    networks:
      motonet:
        ipv4_address: 10.0.1.4
    volumes:
      - /tmp/bootstrap_ec2.py:/opt/init/bootstrap.py
networks:                             
  motonet:                          
    driver: bridge                
    ipam:                         
      config:                       
        - subnet: 10.0.0.0/16

Aslida, bu yondashuv nafaqat ishlab chiquvchining noutbukida qo'llanilishi mumkin. Yig'ishdan so'ng masxara bilan dastlabki sinovlar dev* muhitlarida ishlashda yuzaga kelishi mumkin bo'lgan muammolardan xalos bo'lishga yordam beradi.
