maxwelld 2.1.5

docker compose testing env orchestrator

Maxwell's demon of test enviroment

Orchestrate testing env easily.

Wraps docker-compose and it's dependencies into it's own container with http api.

Execute docker-compose commands sequences for starting requested services set from volumed docker-compose files. Rerun environment when in-flight one is different from new requested.

Vedro usage

Add "supervisor" container

  maxwelld:
    image: docker.io/ko10ok/maxwelld:0.2.9
    volumes:
      - .:/project
      - ./docker-composes:/docker-composes
      - ./env-tmp:/env-tmp
    environment:
      - DOCKER_HOST=tcp://dockersock:2375
      - COMPOSE_PROJECT_NAME=${COMPOSE_PROJECT_NAME}
      - NON_STOP_CONTAINERS=dockersock,maxwelld,e2e
      - HOST_PROJECT_ROOT_DIRECTORY=${HOST_PROJECT_ROOT_DIRECTORY}

Define services config

# env_set.py
from maxwelld import Environments
from maxwelld import Environment
from maxwelld import DEFAULT_ENV
from maxwelld import Service

web = Service('web')
web_gallery = Service('web-gallery')  # Service names "web-gallery", "mq", etc from docker-compose.yml
mq = Service('mq')
db = Service('db')

class Envs(Environments):
    DEFAULT = Environment(
        DEFAULT_ENV,
        web, web_gallery,
        db,
        mq
    )

Enable plugin

from maxwelld import vedro_plugin as vedro_maxwell
from maxwelld import ComposeConfig
from env_set import Envs

class Config(vedro.Config):

    class Plugins(vedro.Config.Plugins):
        
        class VedroMaxwell(vedro_maxwell.VedroMaxwell):
            enabled = True
            envs = Envs()
            compose_cfgs = {
                'default': ComposeConfig('docker-compose.yml', parallel_env_limit=1),
                'dev': ComposeConfig('docker-compose.yml:docker-compose.dev.yml', parallel_env_limit=1),
            }

How To Start Contributing

Run e2e tests

cd tests
make watch  # separate terminal to watch for changes
make e2e-run

# verbose output 
make e2e-run args='-vvv'

# specific test
make e2e-run args='scenarios/api/up_env_with_custom_services_set_enviroment.py -vvv'

Update in-image maxwelld library / rebuild dependencies

make watch -B  # kill & restart existing watcher
# or
make e2e-run -B  # rebuild before test run

Run in-project integrated

Client changes testing (e2e vedro)

Add volume with package

  e2e:
    volumes:
      - /Users/***/repos/maxwelld:/maxwelld

and update in started container

docker-compose exec e2e /venv/bin/python3 -m pip install /maxwelld

Server changes testing

make beta image

make build-image-beta

and change it for ur project

    image: docker.io/***/maxwelld:*.*.*-beta
