Dockerfiles multiple crash when creating images in docker

Question

I want to create a docker layout to eliminate the number of commands needed to run my tests. My goal is to run the ONE command and it will launch my containers and run my tests. This is my first time you create a docker file, so please be patient. The docker-compose.file is located next to two other dock files. Below are the dockers that I initiated, but I can't even create images. I tried to indicate the purchase path with the addition of "volumes: ...", but it still does not work.

services:
      headless-chrome:
        build: ./Dockerfile-headless-chrome
      dev-server:
        build: ./Dockerfile

To run the tests, I use this: Shell 1:

$ SCHEME=http ENV=stage DOCKER_DEV_ENTRYPOINT='"npm run dev-server"' make docker-dev

When this is done, I need to run below in a new shell (shell 2):

$ docker build -t headless-chrome -f Dockerfile-headless-chrome .
$ docker run -it --rm --net=host --cap-add=SYS_ADMIN headless-chrome /bin/bash

Then when Im inside the Im container works:

$ npm run selenium-docker
$ npm run uat

Answer 1

TypeError: You must specify a directory to build in path

build: ./Dockerfile-headless-chrome docker-compose.yml, , Dockerfile. , , - build → dockerfile:

  services:
    headless-chrome:
      build:
        context: .
        dockerfile: Dockerfile-alternate
    dev-server:
      build: .

dev-server , (context: . dockerfile: Dockerfile). context: . , .

. , /bin/bash.

(entrypoint.sh):

npm run selenium-docker
npm run uat

(ADD) (CMD).

# Dockerfile

... your commands

ADD entrypoint.sh
CMD bash entrypoint.sh

. docker-compose build ( Docker) docker-compose up
