lacquerlabs/service-flask repository overview

⁠service-flask

Quick and dirty nginx => gunicorn => python2/flask docker image based on alpine 3.7

⁠Assumptions

• you have docker installed
• you have make tools
• you like lists

⁠Quick start

• do make build You should see the container build up
• do make runvolume now point your browser at http://localhost:8080/⁠ and see "hello world!"
• edit the ./code/main.py and change the hello to bonjour now point your browser at http://localhost:8080/⁠ and see "bonjour world!". It might take a few reloads to reflect code change, this is due to the -reload in the gunicorn command switches.
• finally make kill to clean it up

⁠How to

• Put your app in ./code
• Use the Makefile with make (will display helps)
• the docker file assumes your app is started with "main:app" so edit this accordingly and rebuild the docker file

⁠Want to build it manually? cool, cool..

• build it docker build --pull -t flaskapp .

• run it on port 80 docker run -p 80:80 --name flaskapp_run --rm -id flaskapp

• run it on port 80, but also mount the ./code directory so you can make live edits docker run -p 80:80 --name flaskapp_run -v ${PWD}/code:/app --rm -id flaskapp NOTE: You'll have to rebuild the docker image after you're done making changes if you want the image to have your new codebase.

• connect to it while it's running docker exec -it flaskapp_run /bin/sh

• watch the pretty logs docker logs -f flaskapp_run

• kill it docker kill flaskapp_run

There are other options in the Makefile too, so really, use that.
