How do I change the config.yml in sentry docker?

I have setup sentry with docker in a machine. I would like to integrate GitHub plugin. For this I need to add some settings to the config file.

The docker compose file is, ,

version: '2'

services:
  redis:
    image: redis

  postgres:
    image: 'postgres'
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
      POSTGRES_DBNAME: sentry
      POSTGRES_DBUSER: sentry
      POSTGRES_DBPASS: sentry
    volumes:
     - ~/sentry/data:/var/lib/postgresql/data

  sentry:
    image: sentry
    depends_on:
     - redis
     - postgres
    links:
     - redis
     - postgres
    ports:
     - 9000:9000
    environment:
      SENTRY_SECRET_KEY: '<SECRET-KEY>'
      SENTRY_POSTGRES_HOST: postgres
      SENTRY_DB_USER: postgres
      SENTRY_DB_PASSWORD: postgres
      SENTRY_REDIS_HOST: redis
      SENTRY_SERVER_EMAIL: '<FROM-EMAIL>'
      SENTRY_EMAIL_HOST: <EMAIL-HOST>
      SENTRY_EMAIL_PORT: <EMAIL-PORT>
      SENTRY_EMAIL_USER: '<USER-NAME>'
      SENTRY_EMAIL_PASSWORD: '<USER-PASSWD>'
      SENTRY_EMAIL_USE_TLS: 'true'

  sentry-cron:
    image: sentry
    depends_on:
     - redis
     - postgres
    command: "sentry run cron"
    environment:
      SENTRY_SECRET_KEY: '<SECRET-KEY>'
      SENTRY_POSTGRES_HOST: postgres
      SENTRY_DB_USER: postgres
      SENTRY_DB_PASSWORD: postgres
      SENTRY_REDIS_HOST: redis
      SENTRY_SERVER_EMAIL: '<FROM-EMAIL>'      
      SENTRY_EMAIL_HOST: <EMAIL-HOST>
      SENTRY_EMAIL_PORT: <EMAIL-PORT>
      SENTRY_EMAIL_USER: '<USER-NAME>'
      SENTRY_EMAIL_PASSWORD: '<USER-PASSWD>'
      SENTRY_EMAIL_USE_TLS: 'true'

  sentry-worker-1:
    image: sentry
    depends_on:
     - redis
     - postgres
    command: "sentry run worker"
    environment:
      SENTRY_SECRET_KEY: '<SECRET-KEY>'
      SENTRY_POSTGRES_HOST: postgres
      SENTRY_DB_USER: postgres
      SENTRY_DB_PASSWORD: postgres
      SENTRY_REDIS_HOST: redis
      SENTRY_SERVER_EMAIL: '<FROM-EMAIL>'      
      SENTRY_EMAIL_HOST: <EMAIL-HOST>
      SENTRY_EMAIL_PORT: <EMAIL-PORT>
      SENTRY_EMAIL_USER: '<USER-NAME>'
      SENTRY_EMAIL_PASSWORD: '<USER-PASSWD>'
      SENTRY_EMAIL_USE_TLS: 'true'

The containers running are,

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

I found a config file in /etc/sentry in sentry_1 container. Is the config file or am I missing up something? Thank you for any help.

Solution

If you see the documentation they suggest to use custom image using .

sentry:onbuild

This image makes it easy to custom build your own Sentry instance by copying in a custom config.yml and/or sentry.conf.py file and installing plugins from requirements.txt.

It's also possible to develop custom extensions within your onbuild package. If the build directory contains a setup.py file, this will also get installed.

See the official Sentry documentation for more information.

To create your custom sentry:onbuild package, simply do the following:

Create a Dockerfile containing FROM sentry:onbuild In the same directory, add your custom configuration files. You can get copies of those files to use as templates from the docker-sentry GitHub repo. Build your image: docker build -t mysentry . Run your custom image using mysentry instead of sentry.
