When I build my app without using docker-compose :
docker build -t aspnetapp .
docker run -d -p 8080:80 --name myapp aspnetapp
the docker container runs just fine. But when I try to run it, using docker-compose up, the image builds successfully but the website gives me errors on loading.
dockerfile:
FROM microsoft/dotnet:sdk AS build-env
WORKDIR /app
RUN curl -sL https://deb.nodesource.com/setup_10.x | bash -

# Copy csproj and restore as distinct layers
COPY *.csproj ./
RUN dotnet restore
# Copy everything else and build
COPY . ./
RUN dotnet publish -c Release -o out
# Build runtime image
FROM microsoft/dotnet:aspnetcore-runtime
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "app.dll"]
docker-compose:
version: '3.4'
services:

removing
environment: - ASPNETCORE_ENVIRONMENT=Development
from the compose.override file fixed all this. I'm not sure why it's the problem.
Is your Dockerfile in ./ or ./app? If it's in ./ change docker-compose.yml to build: ./
EDIT
I've just realised that you are specifying both image and build in your docker-compose.yml; get rid of the image.

I have NestJS monorepo project with structure as below:
...
apps
app1
app2
app3
...
If I got an idea correctly, I have possibility to run all the applications in same time, i.e. I run command and have access to apps by paths like http://my.domain/app1/, http://my.domain/app2/, http://my.domain/app3/ or in some similar way. And I need to put all apps in a docker container(s) and run them from there.
I haven't found something about this proceess. Did I undestand the idea correctly and where could I know more about deployment NestJS monorepo project?
This is how I solved it:
apps
app1
Dockerfile
...
app2
Dockerfile
...
app3
Dockerfile
...
docker-compose.yml
Each Dockerfile does the same:
FROM node:16.15.0-alpine3.15 AS development
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build
FROM node:16.15.0-alpine3.15 AS production
ARG NODE_ENV=production
ENV NODE_ENV=${NODE_ENV}
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install --only=production --omit=dev
COPY --from=development /usr/src/app/dist ./dist
CMD ["npm", "run", "start-app1:prod"]
Where the last line should start the application so adjust that to your project naming.
Later you should build each of the images in your CI/CD pipeline and deploy them separately. To run the docker build from the root folder of the project you just need to provide a Dockerfile path for -f parameter, for example:
docker build -f apps/app1/Dockerfile -t app1:version1 .
docker build -f apps/app2/Dockerfile -t app2:version1 .
docker build -f apps/app3/Dockerfile -t app3:version1 .
To run it locally for tests, utilize docker-compose.yml
version: '3.8'
services:
app1:
image: app1:version1
ports:
- 3000:3000 # set according to your project setup
app2:
...
app3:
...
And start it by calling docker compose up
I have this files:
docker-compose.yml (shortened):
version: '3.7'
services:
php-fpm:
build:
context: .
dockerfile: docker/php/Dockerfile
target: dev
volumes:
- .:/app
frontend:
build:
context: .
dockerfile: docker/php/Dockerfile
target: frontend
volumes:
- .:/app
docker/php/Dockerfile (shortened):
FROM alpine:3.13 AS frontend
WORKDIR /app
COPY . .
RUN apk add npm
RUN npm install
RUN npx webpack -p --color --progress
FROM php:7.4-fpm AS dev
ENTRYPOINT ["docker-php-entrypoint"]
WORKDIR /app
COPY ./docker/php/www-dev.conf /usr/local/etc/php-fpm.d/www.conf
CMD ["php-fpm"]
I want to use all what building in frontend (as I understood at the stage build at this time volumes are not available) in php-fpm container, but I get something like this: file_get_contents(/app/static/frontend.version): failed to open stream.
How I can do this? I don't understand very well in Docker and the only solution I have is to move build script to php-fpm container.
You need to delete the volumes: in your docker-compose.yml file. They replace the entire contents of the image's /app directory with content from the host, which means everything that gets done in the Dockerfile gets completely ignored.
The Dockerfile you show uses a setup called a multi-stage build. The important thing you can do with this is build the first part of your image using Node, then COPY --from=frontend the static files into the second part. You do not need to declare a second container in docker-compose.yml to run the first stage, the build sequence runs this automatically. This at a minimum looks like
COPY --from=frontend /app/build ./static
You will also need to COPY the rest of your application code into the image.
If you move the Dockerfile up to the top of your project's source tree, then the docker-compose.yml file becomes as simple as
version: '3.8'
services:
php-fpm:
build: . # default Dockerfile, default target (last stage)
# do not overwrite application code with volumes:
# no separate frontend: container
But you've put a little bit more logic in the Dockerfile. I might write:
FROM node:lts AS frontend # use a prebuilt Node image
WORKDIR /app
COPY package*.json . # install dependencies first to save time on rebuild
RUN npm install
COPY . . # (or a more specific subdirectory?)
RUN npx webpack -p --color --progress
FROM php:7.4-fpm AS dev
WORKDIR /app
COPY . . # (or a more specific subdirectory?)
COPY --from=frontend /app/build ./static
COPY ./docker/php/www-dev.conf /usr/local/etc/php-fpm.d/www.conf
# don't need to repeat unmodified ENTRYPOINT/CMD from base image
I'm trying to copy my ./dist after building my angular app.
here is my Dockerfile
# Create image based off of the official Node 10 image
FROM node:12-alpine
RUN apk update && apk add --no-cache make git
RUN mkdir -p /home/project/frontend
# Change directory so that our commands run inside this new directory
WORKDIR /home/project/frontend
# Copy dependency definitions
COPY package*.json ./
RUN npm cache verify
## installing packages
RUN npm install
COPY ./ ./
RUN npm run build --output-path=./dist
COPY /dist /var/www/front
but when I run docker-compose build dashboard I get this error
Service 'dashboard' failed to build: COPY failed: stat /var/lib/docker/tmp/docker-builderxxx/dist: no such file or directory
I don't know why is there something wrong?
if you need to check also docker-compose file
...
dashboard:
container_name: dashboard
build: ./frontend
image: dashboard
container_name: dashboard
restart: unless-stopped
networks:
- app-network
...
The Dockerfile COPY directive copies content from the build context (the host-system directory in the build: line) into the image. If you're just trying to move around content within the image, you can RUN cp or RUN mv to use the ordinary Linux shell commands instead.
RUN npm run build --output-path=./dist \
&& cp -a dist /var/www/front
I am new to docker.
I have created a Dockerfile which runs an Angular application inside nginx+docker.
### STAGE 1: Build ###
FROM node:12.7-alpine AS build
WORKDIR /usr/src/app
COPY package.json package-lock.json ./
RUN npm install
COPY . .
RUN npm run build
### STAGE 2: Run ###
FROM nginx:1.17.1-alpine
COPY nginx.conf /etc/nginx/nginx.conf
COPY --from=build /usr/src/app/dist/jenkins-test /usr/share/nginx/html
to run this i do docker build -t my-app-multistage-image . and after that to run container I do docker run --name my-app-multistage-container -d -p 8888:80 my-app-multistage-image
It is working fine, now I want to use docker-compose to build and run the container, but no idea how to do that, can anyone please help me.
One code i tried which is obviously not working is
version: '3'
services:
web:
build: .
ports:
- "8888:80"
Thanks
I installed Go on Ubuntu 16.04. This is my GOPATH=/home/{username}/work.
I created a project into /home/{username}/work/src.
This is my project folder hierarchy.

I can build and run with my dockerfile but I can't build and up with docker-compose.
I couldn't find any solution.
Configuration service dockerfile:
FROM golang:1.11.1-alpine3.8 as builder
RUN apk update && apk add git && go get gopkg.in/natefinch/lumberjack.v2
RUN mkdir -p /go/src/project-name/services/configuration
RUN CGO_ENABLED=0
RUN GOOS=linux
ADD . /go/src/project-name/services/configuration
ENV GOPATH /go
WORKDIR /go/src/project-name/services/configuration/api
RUN go get
RUN go build
FROM alpine
RUN apk update
RUN apk add curl
RUN mkdir -p /app
COPY --from=builder /go/src/project-name/services/configuration/api/ /app/
RUN chmod +x /app/api
WORKDIR /app
EXPOSE 5001
ENTRYPOINT ["/app/api"]
It works with dockerfile.
This is my docker-compose file:
version: '3.4'
services:
bff:
image: project-name/bff:${TAG:-latest}
build:
context: .
dockerfile: services/bff/Dockerfile
ports:
- "5000:5000"
container_name: bff
depends_on:
- configuration
configuration:
image: project-name/configuration:${TAG:-latest}
build:
context: .
dockerfile: services/configuration/Dockerfile
ports:
- "5001:5001"
container_name: configuration
It didn't work.
When the “run go get” command runs, it gives an error, the error is:
can't load package: package project-name/services/configuration/api: no Go files in /go/src/project-name/services/configuration/api
ERROR: Service 'configuration' failed to build: The command '/bin/sh -c go get' returned a non-zero code: 1
In your Dockerfile, you say
ADD . /go/src/project-name/services/configuration
which expects the build context directory on the host to contain the source files. But your docker-compose.yml file says
build:
context: .
dockerfile: services/configuration/Dockerfile
where the context directory is the root of your source control tree, not the specific Go source directory you're trying to build. If you change this to
build:
context: services/configuration
# Default value of "dockerfile: Dockerfile" will be right
it will likely work better.
In plain Docker commands, your current docker-compose.yml file says the equivalent of
cd $GOPATH/src/project-name
docker build -f services/configuration/Dockerfile .
But you're probably actually running
cd $GOPATH/src/project-name/services/configuration
docker build .
and what directory is the current directory matters.
