Basic Python Flask app in Docker which prints the hostname and IP of the container
Build the Docker image manually by cloning the Git repo.
$ git clone https://github.com/vaanforz/python-flask-docker.git
$ sudo docker build -t flask_image .
Create a container from the image.
$ sudo docker run --name my-container -d -p 8080:8080 flask_image
Now visit http://localhost:8080
The hostname of the container is 6095273a4e9b and its IP is 172.17.0.2.
Verify by checking the container ip and hostname (ID):
$ docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' my-container
172.17.0.2
$ docker inspect -f '{{ .Config.Hostname }}' my-container
6095273a4e9b
