Description

i am trying to use mongodb atlas (dedicated) and i appreciate any help with yml file

What to use with below fields…?

  • MONGO_URL=mongodb://mongo:27017/rocketchat
  • MONGO_OPLOG_URL=mongodb://mongo:27017/local

and below sections, what to do with it

depends_on:
- mongo
ports:
- 3000:3000
labels:
- “traefik.backend=rocketchat”
- “traefik.frontend.rule=Host: your.domain.tld”

mongo:
image: mongo:4.0
restart: unless-stopped
volumes:
- ./data/db:/data/db
#- ./data/dump:/dump
command: mongod --smallfiles --oplogSize 128 --replSet rs0 --storageEngine=mmapv1
labels:
- “traefik.enable=false”

this container’s job is just run the command to initialize the replica set.

it will run the command and remove himself (it will not stay running)

mongo-init-replica:
image: mongo:4.0
command: >
bash -c
“for i in seq 1 30; do
mongo mongo/rocketchat --eval "
rs.initiate({
_id: ‘rs0’,
members: [ { _id: 0, host: ‘localhost:27017’ } ]})” &&
s=$$? && break || s=$$?;
echo “Tried $$i times. Waiting 5 secs…”;
sleep 5;
done; (exit $$s)"
depends_on:
- mongo

Checkout the section on editing mongoDB variables: Docker & Docker Compose - Rocket.Chat Docs

They have an example of what a mongo atlas url looks like. Also checkout this stack overflow answer for an example with values filled in on the variable names: azure - how to connect mongodb with replicaset url? - Stack Overflow
