Build your own Docker image

The docker-custom directory contains files you need to build your own images.

The follow steps describe in short which steps to take to build your own images.

1. git clone

Clone the Node-RED Docker project from github

git clone https://github.com/node-red/node-red-docker.git

Change dir to docker-custom

cd node-red-docker/docker-custom

Change the node-red version in package.json (from the docker-custom directory) to the version you require
Add optionally packages you require

The docker-make.sh is a helper script to build a custom Node-RED docker image.

Change the build arguments as needed:

--build-arg ARCH=amd64 : architecture your are building for (arm32v6, arm32v7, arm64v8, amd64)
--build-arg NODE_VERSION=10 : NodeJS version you like to use
--build-arg NODE_RED_VERSION=${NODE_RED_VERSION} : don't change this, ${NODE_RED_VERSION} gets populated from package.json
--build-arg OS=alpine : the linux distro to use (alpine)
--build-arg BUILD_DATE="$(date +"%Y-%m-%dT%H:%M:%SZ")" : don't change this
--build-arg TAG_SUFFIX=default : to build the default or minimal image
--file Dockerfile.custom : Dockerfile to use to build your image.
--tag testing:node-red-build : set the image name and tag

Run docker-make.sh

$ ./docker-make.sh

This starts building your custom image and might take a while depending on the system you are running on.

When building is done you can run the custom image by the following command:

$ docker run -it -p1880:1880 testing:node-red-build

With the following command you can verify your docker image:

$ docker inspect testing:node-red-build

Dockerfile.custom can be modified as required. To add more applications the scripts/install_devtools.sh can be modified as needed.
