#Notes for building and running docker image/container

build the image

TAG=bc

docker build . -t $TAG

run the container

run with this directory mounted so you can edit locally and have stuff updated

  • note: there is no bash in alpine, so use sh
  • NODE_ENV can be development or production.
  • port 9018 is for karma and 8080 is for the client itself.
  • port 9100 is mentioned in the karma file, but I am still not sure how to use it

docker run -ti --rm --env NODE_ENV=development --mount type=bind,src="$(pwd)",dst=/home/node/workbench-client -p 9018:9018 -p 9100:9100 -p 8080:8080 $TAG sh

or for root user (probably not necessary) docker run -ti --rm --env NODE_ENV=development -u root:root --mount type=bind,src="$(pwd)",dst=/home/node/workbench-client -p 9018:9018 -p 9100:9100 -p 8080:8080 $TAG sh

start it

Within the container interactive mode:

npm install

Note, I have also built the image with RUN npm install to save time if starting and stopping the container a lot

npm start

Karma is configured not to launch a browser, to save having to work with a browser in the container. After the output INFO [karma]: Karma v0.13.22 server started at http://localhost:9018/ on the host, open a browser and navigate to http://localhost:9018?id=12345678 I am not sure if the id is necessary

After the output Note: it seems to take a long time to get past Build webserver directory: build
