This is the portion of the dockerfile that has served us well to date. However, now I need to convert this to be a single node replica set (for transactions to work). I don't want any secondary or arbiter - just the primary node. What am I missing to get this working?
mongo:
image: mongo:4.4.3
container_name: mongo
restart: unless-stopped
environment:
MONGO_INITDB_ROOT_USERNAME: root
MONGO_INITDB_ROOT_PASSWORD: myPass
command: mongod --port 27017
ports:
- '27017:27017'
volumes:
- ./data/mongodb:/data/db
- ./data/mongodb/home:/home/mongodb/
- ./configs/mongodb/mongo-init.sh:/docker-entrypoint-initdb.d/mongo-init.sh:ro
Got it working. I inserted the following into the block in my question above:
hostname: mongodb
volumes:
- ./data/mongodb/data/log/:/var/log/mongodb/
# the healthcheck avoids the need to initiate the replica set
healthcheck:
test: test $$(echo "rs.initiate().ok || rs.status().ok" | mongo -u root -p imagiaRoot --quiet) -eq 1
interval: 10s
start_period: 30s
