Intellij idea use docker-compose can't mappeed native file to the remote docker

I just want to deploy my springboot applicaiton on the remote centos server through the intellij idea.
First I tried the way of DockerFile to deploy the application on intellij idea and I successed.
this is my DockerFile config
FROM williamyeh/java8
# COPY or ADD to image
COPY dockerdemo-0.0.1-SNAPSHOT.jar app.jar
RUN bash -c "touch /app.jar"
EXPOSE 8080
ENTRYPOINT ["java", "-jar", "app.jar"]
but when I tried the method of docker-compose.yml,I failed,I can't mapped my navtive jar to the remote system.my docker-compose.yml config is
version: "3"
services:
dockerDemo2:
image: adoptopenjdk/openjdk8:latest
container_name: dockerDemo2
privileged: true
environment:
TZ: Asia/Shanghai
LANG: es_US.UTF-8
volumes:
- ./dockerdemo-0.0.1-SNAPSHOT.jar:/docker/dockerdemo-0.0.1-SNAPSHOT.jar
command: bash -c " tail -f /dev/null "
ports:
- 8080:8080
I deployed successed,but when I get in the remote docker ,I found the /docker/dockerdemo-0.0.1-SNAPSHOT.jar is a directory, It should expected as a jar file,but it not,I don't know why that.that's really confuesed me.

docker-compose failed to build on windows 10

I'm trying to deploy my spring boot application with docker compose but get this error:
Step 14/15 : COPY ${JAR_FILE} manager.jar
ERROR: Service 'manager' failed to build : When using COPY with more than one source file, the destination must be a directory and end with a /
But if I do a docker build using the Dokerfile it works correctly. The question is, why fail with docker-compose up?.
C:\Push\Workspace\manager>docker build --tag "docker-manager:latest" .
[+] Building 7.3s (8/8) FINISHED
I have tried looking for examples but I am using windows 10
The Dockerfile:
FROM openjdk:8-jdk-alpine
RUN addgroup -S spring && adduser -S spring -G spring
USER spring:spring
ARG JAR_FILE=target/*.jar
COPY ${JAR_FILE} example.jar
ENTRYPOINT ["java", "-jar", "example.jar"]
The docker-compose.yml
services:
oracle:
image: container-registry-london.oracle.com/database/enterprise:12.2.0.1
ports:
- "8080:8080"
- "1521:1521"
manager:
build: .
ports:
- "8181:8181"
depends_on:
- oracle
links:
- oracle
restart: always

I am guessing there might be mulitple jar files in your target folder.
In stead of using the *.jar , please use full name of the jar and then rebuild the dokcer compose file with --build flag.
ARG JAR_FILE=target/test-0.0.1-SNAPSHOT.jar
Then build with
docker-compose up --build

How can I start spring boot application in docker with profile?

I have a simple spring-boot project:
-resources
-application.yaml
-application-test.yaml
And I have this Dockerfile:
FROM openjdk:8-jdk-alpine
EXPOSE 8080
ADD micro-boot.jar micro-boot.jar
ENTRYPOINT ["java","-Dspring.profiles.active=test" "-jar","/micro-boot.jar"]
1) I build image - C:\micro-boot>docker build -f Dockerfile -t micro-boot .
2) show all images - C:\micro-boot>docker image ls -a
micro-boot latest ccc9a75ebc24 4 seconds ago 112MB
3) try to start C:\micro-boot>docker image ls -a
And I get an error:
/bin/sh: [java,-Dspring.profiles.active=test: not found

We have 3 ways:
1. Passing Spring Profile in a Dockerfile
FROM openjdk:8-jre-alpine
...
ENTRYPOINT ["java", "-Djava.security.egd=file:/dev/./urandom","-Dspring.profiles.active=test","-jar","app.jar"]
2. Passing Spring Profile in Docker run
docker run -d -p 8080:8080 -e "SPRING_PROFILES_ACTIVE=test" --name my-app:latest
3. Passing Spring Profile in DockerCompose
version: "3.5"
services:
my-app:
image: my-app:latest
ports:
- "8080:8080"
environment:
- "SPRING_PROFILES_ACTIVE=test"

There's a typo here
ENTRYPOINT ["java","-Dspring.profiles.active=test" comma missing here "-jar","/micro-boot.jar"]

Building a docker image from dockerfile, can't get java to run correctly, but can run java from image as command line parameters in docker run command

I am new to docker and dockerfile files, having just started trying to write them. I have built a simple java console application and can successfully build a docker image from a dockerfile, but if I include
CMD ["java","-jar","app.jar"]
when I try to run the image I always get a bin/sh error, typically "java not found" or the like.
However, when I don't include the CMD line and just use this Dockerfile to build my image
FROM openjdk:8-jre-alpine
COPY app.jar /app.jar
and then run
docker run -it --rm my-container:tag
I can then run
java -jar app.jar
and the application runs as expected.
I can also run
docker run -it --rm my-container:tag java -jar app.jar
and the application runs as expected.
Every guide I read says I should be able to use CMD or ENTRYPOINT as written above, but nothing ever works.
What might I be missing in this simple example?
Thank you,
Trevor
EDIT: I am running docker version 18.06.1-ce-mac73 (26764) on MacOS Sierra. I am not positive that docker works this way, but I have two image versions in my public docker hub. The dockerfile for v1 is:
FROM openjdk:8-jre-alpine
COPY 454calendar.jar app.jar
The dockerfile for v2 is:
FROM openjdk:8-jre-alpine
ENV PROJECT_DIR=/app
WORKDIR $PROJECT_DIR
COPY 454calendar.jar $PROJECT_DIR
If I add
CMD [“java”,”-jar”,”454calendar.jar”]
to the v2 dockerfile and rebuild, I get this error with the docker run command.
/bin/sh: [“java”,”-jar”,”454calendar.jar”]: not found
Without the CMD line, I can run container and it starts right into the /app working directory where I can run the java command and execute the program.
The two versions of the container in my public docker repository do not have the CMD line in their respective dockerfiles.

The solution was maddeningly simple. Thanks to #Rakesh, I checked the configuration for TextEdit on MacOS and saw that Smart Quotes was turned on. Once I turned off that option and retyped the double quotes, then rebuilt and ran the docker container, the application started up just as expected.

I don't see any problem with your approach. I was able to make a HelloWorld application to run with the below Dockerfile.
FROM openjdk:8-jre-alpine
RUN mkdir /app
RUN cd /app
COPY HelloWorld.jar /app/HelloWorld.jar
WORKDIR /app
CMD ["java","-jar", "HelloWorld.jar"]
I'm on the following docker version
docker -v
Docker version 18.06.1-ce, build e68fc7a
docker-compose -v
docker-compose version 1.22.0, build f46880f

How to copy files from other location into Docker image

I am trying to copy files from other location (in windows from D drive that is shared drive also) to my image.
But it is giving me error.
Step 5/8 : ADD ${APP_PATH}/${ARTIFACT}-${VERSION} /opt/tomcat/webapps/${ARTIFACT}-${VERSION}
ADD failed: stat /var/lib/docker/tmp/docker-builder990684261/d:/Application_Build/spring-tournament-portal-0.0.1-SNAPSHOT: no such file or directory
Scenario:
I am trying to make test,build,release phase cycle with the help of docker.
So My Multistage docker file's first version looked like this
FROM maven as build
WORKDIR /usr/local
RUN mkdir app
COPY . /usr/local/app/spring-tournament-portal/
WORKDIR /usr/local/app/spring-tournament-portal
RUN mvn -e package
FROM tomcat
ENV PORT 8080
ENV VERSION 0.0.1-SNAPSHOT
ENV ARTIFACT spring-tournament-portal
ENV JPDA_ADDRESS 8000
ENV JPDA_TRANSPORT dt_socket
COPY --from=build /usr/local/app/${ARTIFACT}/target/${ARTIFACT}-${VERSION} /usr/local/tomcat/webapps/${ARTIFACT}-${VERSION}
WORKDIR /usr/local/tomcat/bin
CMD ["catalina.sh jpda run"]
EXPOSE ${PORT}
But on every build maven fetches its dependency. So it was taking too much time.
So i made another approach. I created two docker files(One for build and other for release).
Over here the role of build docker file does is copy all source code into an image only. So that when i will create container, I could easily create volume for maven dependency to avoid redownloading:-
FROM indiver/tournament-base
RUN apt-get update && \
apt-get install -y \
-o APT::Install-Recommend=false -o APT::Install-Suggests=false \
maven
WORKDIR /usr/local
COPY . /spring-tournament-portal/
WORKDIR /spring-tournament-portal
COPY ./docker/dev/entrypoint.sh /usr/local/bin/entrypoint.sh
ENTRYPOINT ["sh", "/usr/local/bin/entrypoint.sh"]
RUN ["chmod", "+x", "/usr/local/bin/entrypoint.sh"]
Here is entrypoint.sh file
#!/bin/bash
echo "$#" Phase is executing.....
mvn clean "$#"
When i run the image after building docker file with the help of docker-compose.xml. I set volume for dependency folder.
Here is docker compose.xml
version: "2"
services:
test-service:
build:
context: ../../
dockerfile: ./docker/dev/Dockerfile
container_name: "test-service"
command: 'test'
volumes:
- .m2:/root/.m2
build-service:
build:
context: ../../
dockerfile: ./docker/dev/Dockerfile
container_name: "build-service"
command: 'package'
env_file:
- ./EnvironmentConstant.env
volumes:
- .m2:/root/.m2
database-service:
container_name: "database-service"
env_file:
- ./EnvironmentConstant.env
image: mysql
ports:
- "3306:3306"
volumes:
- ./dev-mysql:/var/lib/mysql
networks:
- app-network
networks:
app-network:
driver: bridge
So it does not need to redownload the dependency again that is in .m2 volume.
After that i need to create release image having content of build prepared by maven. But container of build service is already stopped. So i need to use docker cp command to get my prepared build.
docker cp build-service:/spring-tournament-portal/target/spring-tournament-portal-0.0.1-SNAPSHOT D:/Application_Build
Now i want build that is in Application_Build folder should be copied into my release image.
So my release docker file looks like
FROM indiver/tournament-release
ENV APP_PATH=d:/Application_Build
ENV ARTIFACT=spring-tournament-portal
ENV VERSION=0.0.1-SNAPSHOT
ADD ${APP_PATH}/${ARTIFACT}-${VERSION} /opt/tomcat/webapps/${ARTIFACT}-${VERSION}
WORKDIR /opt/tomcat/bin
ENTRYPOINT ["catalina.sh", "jpda", "run"]
EXPOSE ${PORT}
But As i have mentioned above it is giving me error
Step 5/8 : ADD ${APP_PATH}/${ARTIFACT}-${VERSION} /opt/tomcat/webapps/${ARTIFACT}-${VERSION} ADD failed: stat /var/lib/docker/tmp/docker-builder990684261/d:/Application_Build/spring-tournament-portal-0.0.1-SNAPSHOT: no such file or directory.
I tried to copy by COPY and ADD command. But nothing is working. How can i achieve this.
If It can be achieved this with the help of other relatively easy flow. It would be helpful as well.

The Dockerfile reference says:
ADD obeys the following rules:
The path must be inside the context of the build.
...

Overall your approach seems to be too complicated to me and a very non micro-services way of doing things.
I would suggest that you copy your dependencies into the binary that you are creating to create a self contained fat (uber) jar, which you can copy to the docker image, the way spring boot does.
You approach for having separate docker files for different environments is also problematic and could result in unexpected conditions in production.

So I too faced this similar problem .
You can try the below listed command and replace the Square brackets with your path:
"docker cp /[Your Source Directory] [ContainerId]:/[Destination Path]"
