django-docker-kubernetes-shortcuts

with docker terminal commands can get really long :). this is a collection of the most important shortcuts and commands for a django setup with docker for daily use.

docker

• building all containers with docker-compose.yml:
  docker-compose build .

• building single container (service) with docker-compose.yml:
  docker-compose build <servicename>

• starting application cluster with docker-compose.yml:
  docker-compose up

• starting single application with docker-compose.yml:
  docker-compose up <servicename>

django

• running the shell:
  docker-compose run --rm app sh -c "python manage.py shell"

• running the shell with ipython (requires additional configuration):
  docker-compose run --rm app sh -c "python manage.py shell_plus --ipython"

• create superuser:
  docker-compose run --rm app sh -c "python manage.py createsuperuser"

pytest & flake8

• run tests:
  docker-compose run --rm app sh -c "pytest"

• check code-style:
  docker-compose run --rm app sh -c "flake8"

database

• makemigrations:
  docker-compose run --rm app sh -c "python manage.py makemigrations"

• migrate:
  docker-compose run --rm app sh -c "python manage.py migrate"

pip-compile

• creating requirements.txt from requirements.in:
  pip-compile -o requirements.txt

code-styling with pre-commit

• installing (tool requires a .pre-commit-config.yaml):
  pre-commit install

• check code locally (e.g. flake8) use -a to include all files:
  pre-commit run flake8

deployment (gcloud)

• authenticate:
  gcloud auth configure-docker

• get available contexts:
  kubectl config get-contexts

• switch context:
  kubectl config use-context CONTEXT_NAME

• authenticate project:
  gcloud container clusters get-credentials --zone [zone] --project [project]

• get current pods:
  kubectl get pods

• get logs of a pod:
  kubectl logs <podname>
