# iptables -t nat -F
# systemctl stop docker
# iptables -t nat -F
# nmcli c down docker0

# cat app.py
from flask import Flask
from redis import Redis
app = Flask(__name__)
redis = Redis(host='redis', port=6379)
@app.route('/')
def hello():
count = redis.incr('hits')
return 'Hello World! I have been seen {} times.\n'.format(count)
if __name__ == "__main__":
app.run(host="0.0.0.0", debug=True)
