Docker OS Images : NODEJS

Simple container used to run server side executed javascript content. include all nodejs and npm dependency.
Run nodejs main app.js under a container
based on startx/fedora container.
Could use various network protocol (like http, websocket, smtp, telnet) according to the content of the running app.

Available flavours

  • :latest : Fedora core 29 + NodeJS v0.10.36
  • :fc28 : Fedora core 28 + NodeJS v0.10.36
  • :fc27 : Fedora core 27 + NodeJS v0.10.36
  • :fc26 : Fedora core 26 + NodeJS v0.10.36
  • :fc23 : Fedora core 23 + NodeJS v0.10.36
  • :fc22 : Fedora core 22 + NodeJS
  • :fc21 : Fedora core 21 + NodeJS
  • :centos7 : CentOS 7 + NodeJS
  • :centos6 : Centos 6 + NodeJS
  • :alpine3 : Alpine 3.7 + NodeJS 8.11.1

Running from dockerhub registry

  • with docker you can run docker run -it --name="service-nodejs" startx/sv-nodejs from any docker host
  • with docker-compose you can create a docker-compose.yml file with the following content
    image: startx/sv-nodejs:latest
    container_name: "service-nodejs"
      - "/tmp/container/logs/nodejs:/logs"
      - "/tmp/container/nodejs:/data"

Using this image as Openshift Build image

You can use this public image as a base image in your openshift build strategy. You can first import
our openshift image stream
and automatically add them in your service catalog. You can also test our deploy template
or our build and deploy template

# import image streams
oc create -f
# import deploy template and start a sample application
oc create -f
oc process startx-sv-nodejs-template | oc create -f -
# import build and deploy template and start a sample application
oc create -f
oc process startx-sv-nodejs-build-template | oc create -f -

Using this image as S2I builder

You can use this image as an s2i builder image.

s2i build startx/sv-nodejs test-nodejs
docker run --rm -i -t test-nodejs

Docker-compose in various situations

  • sample docker-compose.yml linked to host port 1000
    image: startx/sv-nodejs:latest
    container_name: "service-nodejs"
      - "1000:8080"
  • sample docker-compose.yml with port exposed only to linked services
    image: startx/sv-nodejs:latest
    container_name: "service-nodejs"
      - "8080"
  • sample docker-compose.yml using data container
    image: startx/fedora:latest
    container_name: "service-nodejs-data"
    image: startx/sv-nodejs:latest
    container_name: "service-nodejs"
      - data:rw

Using this image as base container

You can use this Dockerfile template to start a new personalized container based on this container. Create a file named Dockerfile in your project directory and copy this content inside. See docker guide for instructions on how to use this file.

FROM startx/sv-nodejs:latest
#... your container specifications
CMD ["/bin/sx", "run"]

Environment variable

This container is based on startx fedora container who came with
some additional environment variable

Variable Type Mandatory Description
<i>base image environement</i> see environment list
APP_MAIN string yes Path to the application entrypoint. default is /data/nodejs/app.js
LOG_PATH auto auto default set to /logs and used as a volume mountpoint
APP_PATH auto auto default set to /data and used as a volume mountpoint
TMP_APP_PATH auto auto default set to /tmp/nodejs and used to hold app content and copy to $APP_PATH on startup (if $APP_PATH is empty)

Exposed port

Port Description
8080 network port used to communicate with the running application. Network protocol depend on the running app content.

Exposed volumes

Container directory Description
/logs log directory used to record container and nodejs logs
/data data directory served by nodejs. If empty will be filled with app on startup. In other case use content from $TMP_APP_PATH directory

Testing the service

access to the running application accoridn to the protocol(s) used in your application. For webcontent, you can use firefox http://localhost:8000. Change port and hostname according to your current configuration

For advanced users

You want to use this container and code to build and create locally this container, follow theses instructions.

This section will help you if you want to :

  • Get latest version of this service container
  • Enhance container content by adding instruction in Dockefile before build step

You must have a working environment with the source code of this repository. Read and follow how to setup your working environment to get a working directory. The following instructions assume you are at the top level of your working directory.

Build & run a container using docker

  1. Jump into the container directory with cd Services/nodejs
  2. Build the container using docker build -t sv-nodejs .
  3. Run this container
    1. Interactively with docker run -p 8080:8080 -v /logs -it sv-nodejs. If you add a second parameter (like /bin/bash) to will run this command instead of the default entrypoint. Usefull to interact with this container (ex: /bin/bash, /bin/ps -a, /bin/df -h,...)
    2. As a daemon with docker run -p 8080:8080 -v /logs -d sv-nodejs

Build & run a container using docker-compose

  1. Jump into the container directory with cd Services/nodejs
  2. Run this container
    1. Interactively with docker-compose up Startup logs appears and escaping this command stop the container
    2. As a daemon with docker-compose up -d. Container startup logs can be read using docker-compose logs

If you experience trouble with port already used, edit docker-compose.yml file and change port mapping
