An example of complete dockerfile

This project is here to store my default complete Dockerfile.
I pref using a sample to never forget anything and to curl
the file everytime I need to begin a Dockerfile.
There is also here a Dockerfile already ok to deploy flask apps.

Use Dockerfile

• Get the example

curl https://raw.githubusercontent.com/gabyfulchic/complete-dockerfile-example/master/Dockerfile -O
wget https://raw.githubusercontent.com/gabyfulchic/complete-dockerfile-example/master/Dockerfile  

• Dev your image

vim Dockerfile

• Build your image

docker build . -t foo:v0.0.1

• You can check it here

docker images | grep foo

• Run a container using your image

docker run -it --rm -v /file/you/want/to/copy:/tmp/yourfile foo:v0.0.1 sh

Integrate Dockerfile to your production projects

You will maybe host the Dockerfile on your git repository to be close to your app,
and you will need to pass tests when you push a new release of your Dockerfile.
You will avoid human errors & therefore make your production cycle more faster.

You could use gitlab-ci (or Jenkins, circle-ci, travis-ci ...), to make a runner
build your image, send it to a personal repository (Harbor, Nexus ...) and then try
to run a docker container. Then your runner will trigger a script testing for example
with HTTP request your flask app.

Being more efficient with Docker cli

Use aliases to be more efficient, faster and to avoid using tab 1000 times per minute
It will be hard for the first hour, but efficient for the rest of your career 👨🏽‍💻
