when u start a container, it gets its OWN ip address, and localhost INSIDE the container is not the same as the host.
by default, mongodb and mysql cone configured to listen ONLY for localhost…(or 127.0.0.1).
this means the container is listening for connections from INSIDE the container, not outside.
so, you must change the config to listen for the host or other container, or ANY ip address calling it.
So I need to change my mongodb path into
Mongodb-uri= mongodb://localhost:27017/dbname
or
Mongodb-uri= mongodb://192.168.1.174:27017/dbname
if I give any ip address to connect the mongodb I am unable to get it because in my login page inspect I am getting 192.168.99.100:8088/login failed message. so If I try to connect 192.168.99.100:27017 db path it will throw error. I am getting little confusion in this db path and running application ip
Where Should Change? to resolve that problem. and one more question is there any way to run the docker application by using localhost :8088 ? will it run or not.
I need to connect my system or anyother system db to that running application. how to achieve it. can u explain it clearly. I already posted my environment file(mongodb path) and docker running ip. My db or others system db I want to connect by using ip address of the system it is not connecting to the mongodb…
Please help me to login to system.
there are two parts to this
1 the mongodb server
2. the application trying to USE the database
for step 1, in the mongodb startup use mondgd --bind_ip_all
to allow ANY application, on ANY other IP address to connect to the database.
by default, mongodb will ONLY allow applications from the SAME system (host->host, container->container) to connect
see https://docs.mongodb.com/manual/reference/program/mongod/
then 2, the application must use the IP address of the mongodb container, which is NOT the same as the host machine… on linux the container would typically be at 172.17.0.x in that range anyhow…
destination: file
path: c:\data\log\mongod.log
storage:
dbPath: c:\data\db
net:
// Listen to local and LAN interfaces.
bindIp: 127.0.0.1,192.168.1.88,192.168.1.174
port: 27017
where should I give this ip address
when you connect from the application to the db server (container), you would use container_ip_address:27017
which container ip address : application container ip_address or mongodb container ip address?
How to find container ip addresss
@sdetweil
I have used already exists mongo containers which is available in docker. By using pull command i used docker pull mongo
by using docker ps i am getting container id of mongo
Then I used docker inspect container-id (mongo container-id)
it is displaying ip address as 172.1.0.2 now what should give to connect my db.
and also I gave bindIp: 127.0.0.1,172.1.0.2 in mongod.config file
127.0.0.1 is mongodb default ip address.
172.1.0.2 is mongo container ip address
both ip address is not connecting the mongodb
showing mongodb connection error only.
mongodb_uri=“monogdb://172.1.0.2:27017/pmsdb”
mongodb_uri=“monogdb://127.0.0.1:27017/pmsdb”
both is showing error.
I dont know What mistake i am doing here. Please help me to sort out the problem of local db connection with docker application
172.17.0.2 is the ip address of the mongo server…
in the server config set bindIp: 0.0.0.0
0.0.0.0 means any
then restart the mongo server
then from your db client app the connection would be to 172.17.0.2:27017
then I have to run my application ?
docker run -p 8088:8088 nitikishu/samplenodejs
it will run in 192.168.99.100:8088 or 172.17.0.2:8088?
you do not need to map the ports to access the docker container
so, http://172.17.0.2:8088 should work (application/web browser running on the docker host)
this is my mongodb_uri=“mongodb://172.17.0.2:27017/pmsdb” path right?
yes,
AND
the mongodb server config bindip: 0.0.0.0
to allow ANY ip address (docker host or another container) to connect to the database server
this is not reaching the site. I followed ur steps. But still I am unable to get it in this ip address
env file:
MONGODB_URI=mongodb://172.17.0.2:27017/sample_DB
SESSION_SECRET=sample
App_PORT = 8088
mongod.config
systemLog:
destination: file
path: c:\data\log\mongod.log
storage:
dbPath: c:\data\db
net:
bindIp: 0.0.0.0
command:
docker run nitikishu/samplenodejs
on running application every time container ip address will change?
Before u said This ip 192.168.99.100:8082 check the application running host.
Now ur saying 172.17.0.2:8088 host. I have confused. ///Now this ip is not running
I am confused as well… what is your docker host? windows, linux? i cannot remember.
please describe again the two sides of your solution
server side
app side
Hi @sdetweil,
docker-machine env default
Docker_host=“tcp://192.168.99.100:2376”
I am using winodws 8.
I developed one sample application using (mean stack technology). I want to run this application in all environment(in every where also). So I start to use docker to run my sample application. for that I have built , push the image into docker using (docker quickstart terminal). Now when I run that application in docker by docker run nitikishu/samplenodejs command I am getting following message:
> $ docker run -p 8088:8088 nitikishu/samplenodejs
> sampleproject@1.0.0 start /C:Usersuser2Sample
> node server.js
> server running on port 8088
> Press CTRL-C to stop
> MongoDB connection error. Please make sure MongoDB is running.
in my application I gave mongodb path like this:
MONGODB_URI=mongodb://192.168.99.100:27017/sample_DB
App_PORT = 8088
I want to access my system database(I am using the database named as pmsdb) I want to access that db with the sample application in docker.
I dont know how to connect mongodb database into that docker. Which path should I give also I don’t know. Because When I run the application in my system I will use mongodb path ="monogdb://localhost:27017/sample_DB
If I use the same path in docker built application It is not working.
using docker -machine ip address 192.168.99.100:8088 I am running my project. But Db which ip address I should give?
yesterday you said to bind all ip in mongod.config file. I done that by below code
mongodb.cfg file (this file is in mongodb installed path of my local windows system c:mongodb/bin/mongod.cfg)
systemLog:
destination: file
path: c:\data\log\mongod.log
storage:
dbPath: c:\data\db
net:
bindIp: 0.0.0.0
Now How to connect my local db into samplenodejs application which is running in docker.
Mongodb version :3.4.2
ip address of mongodb: 127.0.0.1:27017
Here, I included the steps which I followed to run the application in docker

thanks… it is still unclear what you mean by the word ‘local’ for the mongo db…
do you mean running on the machine on which you started docker.
there is windows machine
there is virtual machine inside windows (the docker host)
and there is the container…
i THINK you are saying you want the application, running in the container on the virtual machine to connect to the mongo DB running natively on windows. (because your steps do not include starting a mongo db server container)
I will wait for your reply…
yes… In my machine I have a mongodb database. I want to access my system and also LAN connected(local machine) database. In my system only I am running docker.
yes @sdetweil… my application running in the docker container. I want to connect to mongodb database which is running in my own system .
