Hi all, i’ve this docker file :
FROM maven:3-openjdk-17 AS build
# Set the working directory in the container
WORKDIR /app
# Copy the pom.xml and the project files to the container
COPY pom.xml .
COPY src ./src
# Build the application using Maven
RUN mvn clean install
# Use an official OpenJDK image as the base image
FROM maven:3-openjdk-17
EXPOSE 8080
COPY target/*.jar app.jar
ENTRYPOINT ["java", "-jar", "/app.jar"]
When I run the docker build after I change something in my project, this configuration not take the new jar file and when I did docker run I didn’t see the change that I’ve done.
I’ve also try to create a new docker file in this way :
# Use an official Maven image as the base image
FROM maven:3-openjdk-17 AS build
# Set the working directory in the container
WORKDIR /app
# Copy the pom.xml and the project files to the container
COPY pom.xml .
COPY src ./src
# Build the application using Maven
RUN mvn clean package
# Use an official OpenJDK image as the base image
FROM openjdk:11-ea-17-jre-slim
# Set the working directory in the container
WORKDIR /app
# Copy the built JAR file from the previous stage to the container
COPY --from=build /app/target/peco-0.0.1-SNAPSHOT.jar .
# Set the command to run the application
CMD ["java", "-jar", "peco-0.0.1-SNAPSHOT.jar"]
but I received error.
Thanks all for support and help.
