Copy docker-compose.yml.sample to docker-compose.yml and fulfill it with your data:
- database name,
- username
- password
- telegram channel name
- your telegram bot token
- etc, etc
After you'll run docker-compose up for the first time you need to create mongo admin user, just like that
docker-compose exec mongo mongo admin
db.createUser({ user: 'your_mongo_admin_name', pwd: 'your_mongo_admin_password', roles: [ { role: "userAdminAnyDatabase", db: "admin" } ] })
And most importantly you should create your mongo database and user with read'n'write permissions
docker-compose exec mongo mongo admin -u your_mongo_admin_name -p your_mongo_admin_password
use your_mongo_database_name;
db.createUser({ user: 'your_mongo_user', pwd: 'your_mongo_user', roles:['readWrite']});
After that all you need it to relaunch docker-compose up and voila, your channel is being fulfilled with pictures of cute and little adorable ponies.
