Commands to create local mongo replica set (in PROD databases should be placed on different servers)
## Run with MONGO_INITDB_ROOT_USERNAME and MONGO_INITDB_ROOT_PASSWORD
or add admin when database is running without authentication mode on
```
use admin
db.createUser({
user: "admin",
pwd: "password",
roles:["root"]
})
```
## Connect to main db container
```
docker exec -it mongodb bash
```
## Login as a admin
```
mongo --host mongodb:27017 -u admin -p --authenticationDatabase admin
```
## Check replica set status
`rs.status()`
`rs.conf()`
## Setup replica set config (add secondary database)
```
config = {
"_id" : "rsMain",
"members" : [
{
"_id" : 0,
"host" : "mongodb:27017"
},
{
"_id" : 1,
"host" : "mongodb2:27017"
},
]
};
```
## Initialize cluster
```
rs.initiate(config);
```
How to connect:
You must use `directConnection=true` connection option (only for test purpose)
```
mongodb://user:password@mongodb:27017/on_chain_data?replicaSet=rs0&authSource=on_chain_data&directConnection=true
```
Properly connection string
```
mongodb://user:password@:27017/on_chain_data?replicaSet=rs0&authSource=on_chain_data
```
### Additional warnings
When i try to initialize databse using docker compose, the `.js` scirpt isn't run. No solution found.
So i throw away idea to use
```
volumes:
- ./docker-entrypoint-replicaset-onedb:/docker-entrypoint-initdb.d
```
and back to use simple env veriables and then manually enter to docker container and run the scripts to initialize replica set etc.
# Helpfull docker compose config from other service
```
