Configuration

• Sample File: dandelion.conf.sample

• First of all, you need to copy the configuration file from sample.

  cp etc/dandelion/dandelion.conf.sample etc/dandelion/dandelion.conf
  

• Generally, you should change the following values:

  [DEFAULT]
  debug: true
  log_file: dandelion.log
  log_dir: /var/log/dandelion
  
  [cors]
  origins: *
  
  [database]
  connection: mysql+pymysql://dandelion:dandelion@127.0.0.1:3306/dandelion
  
  [mqtt]
  host: 127.0.0.1
  port: 1883
  username: root
  password: 123456
  
  [redis]
  connection: redis://root:123456@127.0.0.1:6379?db=0&socket_timeout=60&retry_on_timeout=yes
  
  [token]
  expire_seconds: 604800
  

• At last, you can link the etc/dandelion/dandelion.conf to the /etc/dandelion/dandelion.conf file.

  mkdir -p /etc/dandelion
  DANDELION_PATH=`pwd`
  cd /etc/dandelion
  ln -s ${DANDELION_PATH}/etc/dandelion/dandelion.conf dandelion.conf
  

Build && Run (Linux)

• Build docker image.

  RELEASE_VERSION=`git rev-parse --short HEAD`_`date -u +%Y-%m-%dT%H:%M:%S%z`
  GIT_BRANCH=`git rev-parse --abbrev-ref HEAD`
  GIT_COMMIT=`git rev-parse --verify HEAD`
  docker build --no-cache --pull --force-rm --build-arg RELEASE_VERSION=${RELEASE_VERSION} --build-arg GIT_BRANCH=${GIT_BRANCH} --build-arg GIT_COMMIT=${GIT_COMMIT} -f Dockerfile -t dandelion:latest .
  

• Run dandelion service as container.

  mkdir -p /var/log/dandelion
  docker run -d --name dandelion_bootstrap -e KOLLA_BOOTSTRAP="" -v /etc/dandelion/dandelion.conf:/etc/dandelion/dandelion.conf --net=host dandelion:latest
  docker rm dandelion_bootstrap
  docker run -d --name dandelion --restart=always -v /etc/dandelion/dandelion.conf:/etc/dandelion/dandelion.conf -v /var/log/dandelion:/var/log/dandelion --net=host dandelion:latest
  

Local Development (Linux)

Run server

• Before you run the dandelion server, you need to follow the Configuration section.

  tox -e venv
  source .tox/venv/bin/activate
  uvicorn --reload --reload-dir dandelion --port 28300 --log-level debug dandelion.main:app --host 0.0.0.0
  

• You can visit the OpenAPI swagger document at http://127.0.0.1:28300/docs

Alembic (Database Migration)

• Generate the migration script.

  tox -e venv
  source .tox/venv/bin/activate
  alembic revision --autogenerate -m "xxxx"
  

• Run the migration script and update the database.

  tox -e venv
  source .tox/venv/bin/activate
  alembic upgrade head
  

Tox Tools

• Generate the latest swagger file.

  tox -e genswagger
  

• Generate the latest sample config file.

  tox -e genconfig
  

• Code format and style check.

  tox -e pep8-format
  tox -e pep8
  

Apitest

• install requirement

  pip3 install gabbi
  

• execute test

  ls apitest/*.yaml | xargs gabbi-run 139.196.13.9:28300 --
  ls apitest/*.yaml | xargs gabbi-run localhost:28300 --
  
  # show verbose
  gabbi-run -v all 139.196.13.9:28300 -- apitest/*.yaml
  gabbi-run -v all localhost:28300 -- apitest/*.yaml
