Prerequisites:

• roach-0 - CockroachDB node
• roach-1 - CockroachDB node
• roach-2 - CockroachDB node
• lb - HAProxy acting as load balancer
• roach-cert - Holds certificates as volume mounts

If you are using Google Chrome as your browser, you may want to navigate here chrome://flags/#allow-insecure-localhost and set this flag to Enabled.

start the environment using

docker compose -f docker-compose-secure.yml -f docker-compose-flask.yml up -d --build

• monitor the status of services via docker-compose logs
• in case you need to adjust something in composexample/settings.py, you can use docker-compose logs flask, docker-compose kill flask, docker-compose up -d flask to debug and proceed.

4. visit the CockroachDB UI and login with username roach and password roach
5. visit the HAProxy UI
6. visit the Flask webpage

docker exec -ti roach-0 /bin/bash docker exec -ti roach-1 /bin/bash docker exec -ti roach-2 /bin/bash docker exec -ti lb /bin/sh docker exec -ti roach-cert /bin/sh docker exec -ti client /bin/bash
