Configuration

Either create a configuration file in the config (./config/local.json is ignored by Git in this repository) or use environment variables to configure your installation. In case you are running the published Docker image, you'll need to stick with the environment variables.

The configuration parameters are the following (the environment variable name is in parenthesis):

• server
  • port (PORT) Number Server port number. (Default: 80)
• meshblu
  • protocol (MESHBLU_PROTOCOL) String Meshblu HTTP adapter protocol, either http or https (Default: http).
  • hostname (MESHBLU_HOSTNAME) String Meshblu HTTP adapter hostname.
  • port (MESHBLU_PORT) Number Meshblu HTTP adapter port.
• logger
  • level (LOGGER_LEVEL) String Logger level, one of: error, warn, info, verbose, debug, silly. (Default: info)

Build and run (local)

First, install the dependencies:

npm install --production

Then:

npm run build
npm start

Build and run (local, development)

First, install the dependencies:

npm install

Then, start the server with auto-reload:

npm run start:watch

or, start the server in debug mode:

npm run start:debug

Build and run (Docker, development)

A development container is specified at Dockerfile-dev. To use it, execute the following steps:

1. Build the image:

   docker build . -f Dockerfile-dev -t knot-cloud-bootstrap-dev
   

2. Create a file containining the configuration as environment variables.

3. Run the container:

   docker run --env-file bootstrap.env -p 4000:80 -v `pwd`:/usr/src/app -ti knot-cloud-bootstrap-dev
   

The first argument to -v must be the root of this repository, so if you are running from another folder, replace `pwd` with the corresponding path.

This will start the server with auto-reload.

Run (Docker)

Containers built from the master branch and the published tags in this repository are available on DockerHub.

1. Create a file containining the configuration as environment variables.
2. Run the container:

docker run --env-file bootstrap.env -p 4000:80 -ti cesarbr/knot-cloud-bootstrap
