NoDock

Docker Compose for Node projects with Node, MySQL, MongoDB, NGINX, Memcached, Redis, Certbot and RabbitMQ images

Node + Docker

Why NoDock?

The docker Node.js image is very simple, you give it an entrypoint and it runs it. This is fine for very simple/small scripts but for larger projects you'll probably want something a bit more robust.

The goal of NoDock is to provide a complete environment for your node project: Node.js service(s), databases, web servers, queues, etc. while doing the "wiring" for you.

You can use NoDock for simple projects by using one of the examples or you can build upon them.

Contents

Requirements

Installation

As a git submodule:

git submodule add https://github.com/Osedea/nodock.git

Clone into your project:

git clone https://github.com/Osedea/nodock.git

We recommend you fork this repository if you intend to add project specific scripts/configurations.

Usage

cd nodock
# Run "node" and "nginx"
docker-compose up -d node nginx

To overwrite the docker-compose.yml file you can use a docker-compose.override.yml

# docker-compose.override.yml

version: '3'

services:
    [...]

Examples

We provide examples of configurations you might use for a specific stack. Each example has it's own README file with instructions.

Workspace

The workspace container is where you want to be manually running commands for NoDock. You can use this container to initialize your project, for task-automation, for cronjobs, etc.

Using HTTPS

By default HTTPS is disabled. To enable it, you may use the following settings

# docker-compose.override.yml
[...]
    nginx:
        build:
            args:
                - WEB_SSL=true

Add your certificate to nginx/certs/cacert.pem and the private key to nginx/certs/privkey.pem.

Generate and use a self-signed cert

SELF_SIGNED: "true" will generate the necessary files, do note that SELF_SIGNED: "true" as no effect if WEB_SSL: "false"

# docker-compose.override.yml
[...]
    nginx:
        build:
            args:
                - WEB_SSL=true
                - SELF_SIGNED=true

Use Certbot (Let's Encrypt) to generate the cert

CN must be a publicly accessible address and EMAIL should be the server admin contact email.

# docker-compose.override.yml
[...]
    nginx:
        build:
            args:
                - WEB_SSL=true
    certbot:
        environment:
            - CN=example.com
            - [email protected]

Don't forget to bring up the container if you plan on using certbot (docker-compose up -d certbot).

Running a single non-web container

The default NGINX server block configuration is aimed at web projects but if you want to have a single non-web container you can do something similar to the following configuration.

# docker-compose.override.yml
[...]
    nginx:
        build:
            args:
                -NO_DEFAULT=true
        ports:
            - "10000:10000"

Do note that using NO_DEFAULT makes WEB_REVERSE_PROXY_PORT, WEB_SSL and SELF_SIGNED have no effect.

You will then have to provide your own NGINX server block like so

# nginx/sites/custom-node.conf

server {
    listen 10000 default_server;

    location / {
        proxy_pass http://node:5000;
    }
}

Running multiple node containers

To add more node containers, simply add the following to your docker-compose.override.yml or environment specific docker-compose file.

# docker-compose.override.yml
[...]
    node2: # name of new container
        build:  # reuse the same values from the node service, cannot use extends in docker-compose 3+
            context: ./node
            args:
                - NODE_VERSION=latest
                - PROJECT_PATH=/opt/app/
                - NODE_ENV=production
                - YARN=false
        volumes:
            - ../:/opt/app
        entrypoint: run-nodock "node alternate.js" # the entrypoint for the "node2" container
    nginx:
        ports:
            - "10000:10000" # the port(s) to forward for the "node2" container
        links:
            - node2 # link "nginx" to "node2"

You'll also need to add a server block for "node2".

# nginx/sites/node2.conf

server {
    listen 10000 default_server;

    location / {
        proxy_pass http://node2:8000;
    }
}

Cronjobs

You can run cronjobs in the Workspace by storing them in the workspace/crontab/root file.

# workspace/crontab/root

* * * * * echo "Every Minute" >> /var/log/cron.log

More Options

To customize the NoDock installation, either add a docker-compose.override.yml in the NoDock directory or store environment specific configurations.

docker-compose -f nodock/docker-compose.yml -f docker-compose.dev.yml up -d

Use Yarn

Set the YARN argument to true.

# docker-compose.override.yml
[...]
    node:
        build:
            args:
                - YARN=true

Change the node entrypoint

Use main.js instead of index.js

# docker-compose.override.yml
[...]
    node:
        entrypoint: run-nodock "node main.js"

Change the Node Environment

The default NODE_ENV value is production, you can change it to development by doing the following

# docker-compose.override.yml
[...]
    node:
        build:
            args:
                - NODE_ENV=development

Use a specific Node version

The default node version is latest, this is NOT advisable for production

# docker-compose.override.yml
[...]
    node:
        build:
            args:
                - NODE_VERSION=4.6.0

Change the Node project path

You can specify a PROJECT_PATH to change the directory in which npm will perform it's install command and the directory in which run-nodock will run the entrypoint script. This is most desirable when running more than one Node project at a time since they are bound to each have their own package.json file.

# docker-compose.override.yml
[...]
    node:
        build:
            args:
                PROJECT_PATH: somefolder # note that this is the same as "/opt/app/somefolder"

Change the MySQL database/user/password

# docker-compose.override.yml
[...]
    mysql:
        build:
            args:
                - MYSQL_DATABASE=default_database
                - MYSQL_USER=default_user
                - MYSQL_PASSWORD=secret

Change the PostgreSQL database/user/password

# docker-compose.override.yml
[...]
    postgresql:
        build:
            args:
                - POSTGRES_DB=default_db
                - POSTGRES_USER=default_user
                - POSTGRES_PASSWORD=secret

Change the NGINX reverse proxy port

Use port 8080 instead of 8000 to bind your Node server

# docker-compose.override.yml
[...]
    nginx:
        build:
            args:
                - WEB_REVERSE_PROXY_PORT=8080

Change the timezone

To change the timezone for the workspace container, modify the TZ build argument in the Docker Compose file to one in the TZ database.

For example, if I want the timezone to be New York:

# docker-compose.override.yml
[...]
     workspace:
        build:
            context: ./workspace
            args:
                - TZ="America/New_York"

Use RabbitMQ plugins

At the moment, NoDock supports 2 plugins: Management and Federation.

To activate them, change their values to true in your docker-compose file:

# docker-compose.override.yml
[...]
    rabbitmq:
        build:
            args:
                - MANAGEMENT=true
                - FEDERATION=true

Change the RabbitMQ user/password

# docker-compose.override.yml
[...]
    rabbitmq:
        build:
            args:
                - RABBITMQ_DEFAULT_USER=custom_user
                - RABBITMQ_DEFAULT_PASS=custom_pass

Modify the Redis config

You can edit redis/redis.conf to modify the redis config.
