NodeBB with Docker full chain ( nginx, redis, mongodb )
-
I would like to introduce what I have done with a NodeBB and a docker.

This docker chain of Nginx, NodeBB, Redis, MongoDB(!!) is based on Alpine Linux and
docker-compose
.
This design is mainly for developments and small standalone service rather than large distributable/scalable service.A Major Difference from other many(?) docker implementations is that I don't embed source and config files into images but just mount most of files on a host directory to containers even include NodeBB source and node_modules. There are pros and cons. I'll explain them briefly and we could discuss them.
UPDATE
A
MongoDB
is added as a default DB !!!
And redis is intened to be used for websock blabla, but I'm not sure it's properly working.What I know actually, no errors, no warnings and I can see both of mongo and redis at admin web UI.
If anybody would try this docker chain, please let me know results.
!!! WARNING !!!
I haven't checked yet howmongod
andredis-server
manageSIGTERM
which docker send.
This means that in worst case one can loose data !
Does any body know about this?mongod
andredis-server
has been checked. Safe withdocker stop
but not withdocker kill
Installation
- This chain consists of 4 docker containers each of NodeBB, Redis, MongoDB, Nginx.
- I don't provide compiled images but 10 mins will be more than enough to build them by yourself with this instructions.
- You will get error from a nginx docker if you already have any web server with port 80. I'll explain solutions after lines.
git clone https://github.com/qgp9/nodebb-docker-dev.git nodebb-docker-dev cd nodebb-docker-dev git clone -b v1.x.x https://github.com/NodeBB/NodeBB.git nodebb ./bin/com-nodebb npm install ./bin/com-nodebb npm install socket.io-redis connect ./bin/com-nodebb npm setup ./bin/utils jq -M -s add nodebb/config.json conf/example/redis.josn > tmp.json && mv tmp.json nodebb/config.json ./bin/docker-compose up
- DB:
mongo
, DB address:mongodb
, DB user:admin
, no DB password - If you have a web server already, you have two options
- Remove a nginx from
docker-compose.xml
, connect a port 4567 of NodeBB to host, and you may know how you can connect from your webserver tohttp://127.0.0.1:4567
. Here is a example docker-compose.xml - change a external port of a nginx docker ( example is 8080 ) and connect from your web server to
http://127.0.0.1:8080
. Here is a example docker-compose.xml
- Remove a nginx from
Command line Settings, Upgrade, npm and so on
When you want to do
./nodebb setup
or./nodebb upgrade
ornpm install
on your nodebb, don't do it on Host directory. You have a helper script, do next../bin/com-nodebb ./nodebb setup ./bin/com-nodebb ./nodebb upgrade ./bin/com-nodebb npm install <package>
Also you can open bash and do whatever you want
./bin/com-nodebb bash
- But to edit/add/delete files,
git pull
, you can do it on the host directory ( or with docker, doesn't matter )
Structure
nodebb-docker-dev ├── bin │ ├── com-nodebb # Helper to control NodeBB docker │ └── docker-compose # Docker version of docker-compose for portability ├── conf # All Dockerfile and configuration. │ ├── nginx │ │ ├── Dockerfile │ │ └── nginx.conf │ ├── nodebb-dev │ │ └── Dockerfile │ └── redis │ ├── Dockerfile │ └── redis.conf ├── data │ ├── nginx │ │ └── logs # nginx, site logs │ ├── nodebb # Empty. reserved for future plans. │ └── redis # dump.rgb ( db data ) , redis.log ( log file ) ├── docker-compose.yml └── nodebb # NodeBB source will be here
- All configuration, data( log file ), NodeBB codes are mounted to dockers ( not copied ). So you can just edit them on a host directory.
- All configurations are in a
conf
directory. All data files genereated by nginx, redis are in adata
directory.- Exceptionally
config.json
and a logfile of NodeBB are in nodebb directory for easy management.
- Exceptionally
- This desigin is aimed to archive easy and best development/management system for small standalone service.
- Every improtant files are just under a main directory on a host and dockers act just like applications,
- so you can remove/rebuild docker containers/images freely without any effect to data.
- Also you can easily migrate this chain to new server. What you need is just copy the main directory to new server and rebuild dockers.
- But large distributing/scaling can meet some side effects.
Project Name
When you build a system by
./bin/docker-compose up
, you will see a wired long name of images/container likenodebbdockerdev_nginx
bydocker images
ordocker ps -a
. This is becausedocker-compose
use a directory name as a project nam.
To get a short/readable name , you have recommontable 2 options.- Change the directory name
- Shell variables ( RECOMMENDED but easilly one can make mistakes. smartcd can help )
export COMPOSE_PROJECT_NAME=qgp9
- or you can embed this variable to
./bin/com-nodebb
and./bin/docker-compose
Then you will seeqgp9_nginx
.
And
More details will be .. updated at the github repo soon.
Any questions/comments/ideas/criticizing/WOW/BOO~ ?

I could successfully migrate my old nodebb system to a dockrized chain.
It was ubuntu based and I got some troubles with nginx configurations and ssl keys from letsencrypt, but in the end every things are fine now without large modifications from my orignal github repo.If some body needs/wants, I'll post it and also update the github repo.

Hi! I tried installing your docker container. After executing the instruction "./bin/docker-compose up" I put the nodebb setting in my browser, but then I got one of these errors in the terminal where I ran the docker-container:
error: Error: Redis connection to 127.0.0.1:6379 failed - connect ECONNREFUSED 127.0.0.1:6379
or
error: NodeBB could not connect to your Mongo database. Mongo returned the following error: connect ECONNREFUSED 127.0.0.1:27017

I tried you repo, but unfortunately the Mongo container fails:
mongodb_1 | Error relocating /usr/bin/mongod: _ZNK5boost16re_detail_10600031cpp_regex_traits_implementationIcE17transform_primaryEPKcS4_: symbol not found mongodb_1 | Error relocating /usr/bin/mongod: _ZNK5boost16re_detail_10600031cpp_regex_traits_implementationIcE9transformEPKcS4_: symbol not found nodebbdockerdev_mongodb_1 exited with code 127
Searching StackOverflow it seems this is an issue with Mongo on Alpine...
(I using Docker beta for MacOS, but I don't think this is the issue)
-
npm either isn't installed or is installed incorrectly.

I try to this docker chain, and got some error after exec
sudo ./bin/com-nodebb npm install
