Steps I followed build using docker-compose
I setup python robot framework with flask based application
I created Dockerfile
DockerFile
FROM alpine:latest
COPY . /app
WORKDIR /app
RUN ls -la /
RUN apk add --no-cache sqlite py3-pip
RUN pip3 install -r requirements.txt
ENV FLASK_PORT 8181
ENV FLASK_APP demo_app
CMD ["sh", "run.sh"]
COPY testing/ui/config/ /app/tests/config/
COPY testing/ui/pages/ /app/tests/pages/
COPY testing/ui/steps/ /app/tests/steps/
COPY testing/ui/test_data/ /app/tests/test_data/
COPY testing/ui/tests/ /app/tests/tests/
COPY testing/ui/test_suites/ /app/tests/test_suites/
RUN ls -la /
WORKDIR /app/tests/test_suites/
CMD ["sh","run_ui_negative_tests.sh"]
I created docker-compose file

I have a main domen and 3 subdomains on server are running on it, but I decided to add 3 subdomains and for some reason I get an error (Error: P1001: Can't reach database server at db-subdomen:5436 or 5432 ) . Project Next.js + prisma +docker.
As I understand it, the problem is either inside the scope in the container. Or in the .env file
In the other 3 subdomains , I have the same cat in Dockerfile and env . In docker-compose, which is the same for all projects, everything is also the same, but there is still an error. There may be a typo , I don't know anymore, tk did everything as always
My docker-compose (for all projects , this example for main and one subdomen):

Submodem Dockerfile (the other 3 projects and subdomains have the same problem and there is no problem:

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?

I have a docker setup with AdonisJS 5. I'm currently trying to get it started (and it builds just fine). But as discussed a bit further down, the ace command cannot be found. ace is the CLI package for AdonisJS (think ng for Angular)
This is my Dockerfile:
ARG NODE_IMAGE=node:16.13.1-alpine
FROM $NODE_IMAGE AS base
RUN apk --no-cache add dumb-init
RUN mkdir -p /home/node/app && chown node:node /home/node/app
WORKDIR /home/node/app
USER node
RUN mkdir tmp
FROM base AS dependencies
COPY --chown=node:node ./package*.json ./
RUN npm ci
RUN npm i #adonisjs/cli
COPY --chown=node:node . .
FROM dependencies AS build
RUN node ace build --production
FROM base AS production
ENV NODE_ENV=production
ENV PORT=$PORT
ENV HOST=0.0.0.0
COPY --chown=node:node ./package*.json ./
RUN npm ci --production
COPY --chown=node:node --from=build /home/node/app/build .
EXPOSE $PORT
CMD [ "dumb-init", "node", "service/build/server.js" ]
And this is my docker-compose.yml:

When I run this with docker-compose up everything works, except for the fn_service.
I get the error:

I followed this tutorial, and I can't seem to find anything by googling. I'm sure it's something miniscule.
Any help would be appreciated.
It's my first I use multi-stage and I have this error when I run the docker-compose up:
worker_1 | Error: Unable to access jarfile worker-jar-with-dependencies.jar
So it looks like it doesn't found the file.
Dockerfile
FROM maven:3.5-jdk-8-alpine AS builder
ADD pom.xml .
RUN mvn dependency:resolve
#RUN /bin/sh -c cd src/
RUN mvn package

COPY --from=builder target/worker-jar-with-dependencies.jar .
#RUN java -jar worker-jar-with-dependencies.jar
CMD ["java", "-jar", "worker-jar-with-dependencies.jar"]
and how it looks my docker-compose.yml

It doesn't look like you are adding your source code in the Dockerfile. You only have an ADD command for your pom, but there isn't one for your source. I would say adding something like "COPY src /src" before your "RUN mvn package".
Not sure if you are using springboot, but here is an example of a multi stage build for a springboot app:
FROM maven:3.6.3-jdk-11 AS builder
WORKDIR /workdir/server
COPY pom.xml /workdir/server/pom.xml
RUN mvn dependency:go-offline
COPY src /workdir/server/src
RUN mvn install
RUN mkdir -p target/depency
WORKDIR /workdir/server/target/dependency
RUN jar -xf ../*.jar
FROM openjdk:11-jre-slim
EXPOSE 8080
VOLUME /tmp
ARG DEPENDENCY=/workdir/server/target/dependency
COPY --from=builder ${DEPENDENCY}/BOOT-INF/lib /app/lib
COPY --from=builder ${DEPENDENCY}/META-INF /app/META-INF
COPY --from=builder ${DEPENDENCY}/BOOT-INF/classes /app

You can find this and other good docker-compose examples in this docker repo: https://github.com/docker/awesome-compose
I used docker-compose to create docker containers in my React, Node.js, and Postgres structured project.
After I created Dockerfile and docker-compose.yml, I did docker up 'docker-compose up --build.'
Then, I wasn't be able to create containers, and get an errors.
I get Error says:
Error 1
Error 2
Error 3
How can I fix it and successfully build containers?
