Can you help with running gulp tasks inside the Docker container with docker-compose, so it would compile SCSS files?
My file structure at host machine:
/application
--/config
--/models
--/public
----/scss
----/css
----index.html
----gulfile.js
--/routes
.dockerignore
.gitignore
Dockerfile
docker-compose.yml
package.json
server.js
/application/public/gulpfile.js:
var gulp = require('gulp');
var sass = require('gulp-sass');
gulp.task('sass', function() {
gulp.src('./scss/styles.scss')
.pipe(sass().on('error', sass.logError))
.pipe(gulp.dest('./css'));
});
gulp.task('sass:watch', function() {
gulp.watch('./scss/styles.scss', ['sass']);
});
Dockerfile:
FROM node:6
RUN mkdir -p /app
WORKDIR /app
COPY . /app
RUN npm install nodemon -g && npm install bower -g && npm install gulp -g
RUN cd /app
RUN npm install
RUN cd /app/public && bower install --allow-root
RUN cd /app
COPY . /app
docker-compose.yml:
version: '2'
services:
web:
build: .
command: nodemon /app/server.js
volumes:

depends_on:

mongo:

ports:

restart: always
Ideally, it would be good to run the command from the docker-compose.yml file to start watching scss files inside the /application/public folder, but I wasted couple of days to solve this problem.
Also, I tried to run gulp inside the container. Actually, it works ok, but changes were not reflected at host machine.
Please do not suggest to use ready-made Docker-Hub images. I have used them and they did not solve my issue.
I'll be thankful for any help, links, info or ready-solution.
You can add a separate service in your compose file to run a separate command in a separate container (see the web line & the gulp service line below
version: '2'
services:
web: &web
build: .
command: nodemon /app/server.js
volumes:
- .:/app/
- /app/node_modules
- /app/public
- /app/config
- /app/models
- /app/routes
ports:
- "3000:3000"
depends_on:
- mongo
gulp: *web
command: <gulp command to watch files>
mongo:
image: mongo:latest
ports:
- "27018:27017"
restart: always

When I run the following Dockerfile,in the middle of the process, after installing prisma, the RUN command db-migrate up is stopped. But when I used docker exec bin bash to run it, it worked without any problem. I don't think I can run the app before serving it. But there is a workaround like putting the migration commands as a service in docker-compose.yml. How to achieve it? or if there's any way to run those RUN commands of migration in this Dockerfile?

Now if i install any packages using the host machine it is as expected updated in package.json file and if run
docker-compose build
the package.json is also updated inside the container which is fine, but i feel like this kinda breaks the whole point of having your App Dockerized! , if multiple developers need to work on this App and they all need to install node/npm in their machines whats the point of using docker other than for deployments? so what I do right now is
sudo docker exec -it cebc4bcd9af6 sh //login into server container
run a command e.g
npm i express
it installs the package and updates package.json but the host package.json is not updated and if i run the build command again all changes are lost as Dockerfile copies in the source code of host into container, is there a way to synchronize the client and host? in a way that if i install a package inside my container that should also update the host files? this way i dont need to have node/npm installed locally and fulfills the purpose of having your App Dockerized!
I have created a NX monorepo with angular and nestJS apps and tried very hard to make the reload work inside containers but to no avail. Even though the directories are mounted correctly and I verified that changes in the host are being written inside the container but somehow the process is not picking them up.
I have created a standalone nestJS application and successfully made it work with the container.

Finally, I was able to make it work after a lot of trial and error.
For angular application, changed server command from npx nx serve to npx nx serve --host 0.0.0.0 --poll 2000.
For the Api, add "poll": 2000 option in angular.json at projects.api.architect.build.options
I have also updated Github repo for reference to anyone looking for the same solution.
I'm trying to get nodemon and docker-compose work with each others and I'm having a problem: Every time I run docker-compose up I get the following error: sh: missing ]. Here are the relevant files:

EDIT: Works on pure docker after the comma fix, but doesn't work on docker-compose
In my docker container, I'm trying to install several packages with pip along with installing Bower via npm. It seems however that whichever of pip or npm run first, the other's contents in /usr/local/bin are overwritten (specifically, gunicorn is missing with the below Dockerfile, or Bower is missing if I swap the order of my FROM..RUN blocks).
Is this the expected behavior of Docker, and if so, how can I go about installing both my pip packages and Bower into the same directory, /usr/local/bin?
Here's my Dockerfile:
FROM python:3.4.3
RUN mkdir /code
WORKDIR /code
ADD ./requirements/ /code/requirements/
RUN pip install -r /code/requirements/docker.txt
ADD ./ /code/
FROM node:0.12.7
RUN npm install bower
Here's my docker-compose.yml file:
web:
restart: always
build: .
expose:
- "8000"
links:
- postgres:postgres
#-redis:redis
volumes:
- .:/code
env_file: .env
command: /usr/local/bin/gunicorn myapp.wsgi:application -w 2 -b :8000 --reload
webstatic:
restart: always
build: .
volumes:
- /usr/src/app/static
env_file: .env
command: bash -c "/code/manage.py bower install && /code/manage.py collectstatic --noinput"
nginx:
restart: always
#build: ./config/nginx
image: nginx
ports:
- "80:80"
volumes:
- /www/static
- config/nginx/conf.d:/etc/nginx/conf.d

postgres:
restart: always
image: postgres:latest

ports:

Update: I went ahead and cross-posted this as a docker-compose issue since it's unclear if there is an actual bug or if my configuration is a problem. I'll keep both posts updated, but do post in either if you have an idea of what is going on. Thanks!
You cannot use multiple FROM commands in Dockerfile and you cannot create image from 2 different base images. So if you need node and python in the same image you could either add node to python image or add python to node image.
