Where is the config.yml file located in sentry docker?

I used this docker-compose file to successfully run sentry on premise. How do i change the config file? Where is it located?

The running containers are,

root@sentry:~# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS                    NAMES

Thank you.

most configuration has already been exposed out as environment, so you can directly change them in the docker-compose.yml file.

for more deep fine tuning, please check out sentry on Github, where you can find the config.yml.

After changing, run install.sh to update the docker images.
