I am trying to get webpack setup on my docker container. It is working, and running, but when I save on my local computer it is not updating my files in my container. I have the following docker-compose file:
version: '2'
services:
web:
build:
context: .
dockerfile: docker/web/Dockerfile
container_name: arc-bis-www-web
restart: on-failure:3
environment:
FPM_HOST: 'php'
ports:
- 8080:8080
volumes:
- ./app:/usr/local/src/app
php:
build:
context: .
dockerfile: docker/php/Dockerfile
environment:
CRM_HOST: '192.168.1.79'
CRM_NAME: 'ARC_test_8_8_17'
CRM_PORT: '1433'
CRM_USER: 'sa'
CRM_PASSWORD: 'Multi*Gr4in'
volumes:
- ./app:/usr/local/src/app
node:
build:
context: .
dockerfile: docker/node/Dockerfile
container_name: arc-bis-www-node
volumes:
- ./app:/usr/local/src/app
and my node container is run by the following dockerfile:
FROM node:8
RUN useradd --create-home user
RUN mkdir /usr/local/src/app
RUN mkdir /usr/local/src/app/src
RUN mkdir /usr/local/src/app/test
WORKDIR /usr/local/src/app
# Copy application source files
COPY ./app/package.json /usr/local/src/app/package.json
COPY ./app/.babelrc /usr/local/src/app/.babelrc
COPY ./app/webpack.config.js /usr/local/src/app/webpack.config.js
COPY ./app/test /usr/local/src/app/test
RUN chown -R user:user /usr/local/src/app
USER user
RUN npm install
ENTRYPOINT ["npm"]
Now I have taken out the copy calls from above and it still runs fine, but neither option is allowing me to save files locally and have them show up in the localhost for my container. Ideally, I thought having a volume would allow me to update my local files and have it read by the volume in the container. Does that make sense? I am still feeling my way around Docker. Thanks in advance for any help.
If you start your container with -v tag, you can map the container and your local storage. You can find more information here.

Dockerfile:
FROM node:18.13.0

docker-compose.yml:
version: '3.8'
services:

build: .
command: sh -c "npx prisma migrate deploy && npm start"
restart: unless-stopped
depends_on:

volumes:

The container fetches new files and saves them into a directory configured by the app running in the container, defaulting to data/. The issue is that they're all created as root and cannot be manipulated by the host. If I chown the dir on the host, it works, but any new files are then created as root again.
I've tried a couple different variations of creating a new user in Dockerfile and passing host user info into the compose file but it always seems to result in a disconnect between the Dockerfile and compose file. I'm trying to keep things as easy as docker compose up, if possible.
I am new in docker. I've built an application with VueJs2 that interacts with an external API. I would like to run the application on docker.
Here is my docker-compose.yml file
version: '3'
services:
ew_cp:
image: vuejs_img
container_name: ew_cp
build:
context: .
dockerfile: Dockerfile
volumes:
- '.:/app'
- '/app/node_modules'
ports:
- '8080:8080'
Here is my Dockerfile:
FROM node:14.17.0-alpine as develop-stage
WORKDIR /app
COPY package*.json ./
RUN npm install
RUN yarn install
COPY . .
EXPOSE 8080
CMD ["node"]
Here is the building command I run to build my image an container.
docker-compose up -d
The image and container is building without error but when I run the container it stops immediately. So the container is not running.
Are the DockerFile and compose files set correctly?
First of all you run npm install and yarn install, which is doing the same thing, just using different package managers. Secondly you are using CMD ["node"] which does not start your vue application, so there is no job running and docker is shutting down.
For vue applicaton you normally want to build the app with static assets and then run a simple http server to serve the static content.
FROM node:lts-alpine
# install simple http server for serving static content
RUN npm install -g http-server
# make the 'app' folder the current working directory
WORKDIR /app
# copy 'package.json' to install dependencies
COPY package*.json ./
# install dependencies
RUN npm install
# copy files and folders to the current working directory (i.e. 'app' folder)
COPY . .
# build app for production with minification
RUN npm run build
EXPOSE 8080
CMD [ "http-server", "dist" ]
Your docker-compose file could be as simple as
version: "3.7"
services:
vue-app:
build:
context: .
dockerfile: Dockerfile
container_name: vue-app
restart: always
ports:
- "8080:8080"
networks:
- vue-network
networks:
vue-network:
driver: bridge
to run the service from docker-compose use command property in you docker-compose.yml.
services:
vue-app:
command: >
sh -c "yarn serve"
I'm not sure about the problem but by using command: tail -f /dev/null in your docker-compose file , it will keep up your container so you could track the error within it and find its problem. You could do that by running docker exec -it <CONTAINER-NAME> bash and track the error logs in your container.
version: '3'
services:
ew_cp:
image: vuejs_img
container_name: ew_cp
build:
context: .
dockerfile: Dockerfile
volumes:
- '.:/app'
- '/app/node_modules'
command: tail -f /dev/null
ports:
- '8080:8080'
In your Dockerfile you have to start your application e.g. npm run start or any other scripts that you are using for running your application in your package.json.
I'm new to Rasa and Docker I want to deploy my rasa project in Docker. I can't find right flow for deployment. what I understood for deployment from blogs and docker videos and tried like this.
First step: I have to create a docker image contains project source and requirements.
Dockerfile
FROM rasa/rasa
COPY . /chatbot
WORKDIR /chatbot
RUN pip install -r requirements.txt
USER root
COPY ./actions /app/actions
USER 1001
requirements.txt
pyaml
flask
requests
spacy
rasa-nlu
rasa-core
rasa-core-sdk
Second step: Create Docker-compose.yml
version: "3.0"
services:
rasa:
image: rasa/rasa:2.6.3-full
ports:
- 5005:5005
volumes:
- ./:/app
command:
- run
- -m
- models
- --enable-api
- --cors
- "*"
- --debug
action_server:
image: rasa/rasa_core_sdk:latest
ports:
- 5055:5055
volumes:
- ./actions:/app/actions
command:
- rasa
- run
- actions
Can anyone tell me right flow for deployment.
Installed docker and docker-compose on your system.
Create the first Dockerfile (just a new file with name “Dockerfile”) in root directory of the project and should have this content -
FROM rasa/rasa:2.8.0
WORKDIR '/app'
COPY . /app
USER root
# WORKDIR /app
# COPY . /app
COPY ./data /app/data
RUN rasa train
VOLUME /app
VOLUME /app/data
VOLUME /app/models
CMD ["run","-m","/app/models","--enable-api","--cors","*","--debug" ,"--endpoints", "endpoints.yml", "--log-file", "out.log", "--debug"]
Note that you can change the rasa version here.
Create second Dockerfile in actions folder and place this content -
FROM rasa/rasa-sdk:2.8.0
WORKDIR /app
COPY requirements.txt requirements.txt
USER root
RUN pip install --verbose -r requirements.txt
EXPOSE 5055
USER 1001
Note that you have to put requirements.txt file containing python libraries that you installed and used in the actions folder.
So, That was all the dockerfiles we needed, now in the root directory, you can see a file called endpoints.yml. change the name localhost to action_server (we’ll register this name in the docker-compose file for container of action server) in the action_endpoint and it should look like -
action_endpoint:
url: "http://action_server:5055/webhook"
Finally, create a docker-compose.yml file in the root directory and place these content -
version: '3'
services:
rasa:
container_name: "rasa_server"
user: root
build:
context: .
volumes:
- "./:/app"
ports:
- "5005:5005"
action_server:
container_name: "action_server"
build:
context: actions
volumes:
- ./actions:/app/actions
- ./data:/app/data
ports:
- 5055:5055
After all this you can just run the command
docker-compose up --build

It looks correct to me. I followed the same structure, except the commands in action_server (inside docker-compose.yml) . I skipped the command part, it was working fine.
action-server:
image: rasa/rasa-sdk:1.10.2
volumes:
- ./actions:/app/actions
ports:
- 5055:5055
And in endpoints url, the name of the service i.e. 'action_server' will only come
That looks like a correct way to deploy your bot using docker. What is the issue you're facing?
Hello i tried to build docker-compose in my project with these structure file:
app/
-front-end/src/Components
-back-end/images
but when i run build i have these error with img relative url:
frontend_1 | Module not found: Can't resolve '../../../../../back-end/images'
And these is my docker-compose file:
version: '2'
services:
backend:
network_mode: host
build: ./back-end/
ports:
- "6200:6200"
volumes:
- ./back-end:/usr/src/app
frontend:
build: ./front-end/
ports:
- "3000:3000"
volumes:
- ./front-end:/usr/src/app
depends_on:
- backend
My frontend Dockerfile:
FROM node:10.15.3
RUN mkdir -p /usr/src/app
WORKDIR /TuKanasta
EXPOSE 3000
CMD ["npm", "start"]
the backend Dockerfile:
FROM node:10.15.3
RUN mkdir -p /usr/src/app
WORKDIR /TuKanasta
RUN npm install -g nodemon
EXPOSE 4000
CMD [ "npm", "start" ]
Note: My project run 100 % without docker.
volumes:
- ./back-end:/usr/src/app
...
volumes:
- ./front-end:/usr/src/app
If set in the same image, the second bind mount volume would overwrite the first /usr/src/app content, as illustrated in gladiusio/gladius-archive-node issue 4.
If set in two different images, /usr/src/app in frontend1 would not be able to see back-end, copied in /usr/src/app separate volume of backend service.
Declaring the volume as external might help, as illustrated in this thread.
Or copying into an existing volume (shown here)
I'm trying to have one service to build my client side and then share it to the server using a named volume. Every time I do a docker-compose up --build I want the client side to build and update the named volume clientapp:. How do I do that?
docker-compose.yml
version: '2'
volumes:
clientapp:
services:
database:
image: mongo:3.4
volumes:
- /data/db
- /var/lib/mongodb
- /var/log/mongodb
client:
build: ./client
volumes:
- clientapp:/usr/src/app/client
server:
build: ./server
ports:
- "3000:3000"
environment:
- DB_1_PORT_27017_TCP_ADDR=database
volumes:
- clientapp:/usr/src/app/client
depends_on:
- client
- database
client Dockerfile
FROM node:6
ENV NPM_CONFIG_LOGLEVEL warn
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
COPY package.json /usr/src/app
RUN npm install
COPY . /usr/src/app
# builds my application into /client
CMD ["npm", "build"]
By definition, a volume is the persistent directories that docker won't touch other than to perform an initial creation when they are empty. If this is your code, it probably shouldn't be a volume.
With that said, you can:
Delete the volume between runs with docker-compose down -v and it will be recreated and initialized on the next docker-compose up -d.
Change your container startup scripts to copy the files from some other directory in the image to the volume location on startup.
Get rid of the volume and include the code directly in the image.
I'd recommend the latter.
Imagine you shared your src folder like this :
...
volumes:
- ./my_src:/path/to/docker/src
...
What worked for me is to chown the my_src folder :
chown $USER:$USER -R my_src
It turned out some files were created by root and couldn't be modified by docker.
Hope it helps !
