I have a project with Spring Boot, MySQL, Liquibase. I wanted to run it through Docker, and added Dockerfile:
FROM openjdk:8
VOLUME /tmp
ADD target/{name_of_project}.jar {name_of_project}.jar
RUN bash -c 'touch /{name_of_project}.jar'
EXPOSE 8080
ENTRYPOINT ["java","-jar","{name_of_project}.jar"]
Building the app like this: docker build -t {name_of_project} .
Then I added app to https://hub.docker.com/
In server (CentOS 7) I run mysql like this:
docker run -d -p 3306:3306 --name {name_of_mysql} -e MYSQL_ROOT_PASSWORD={pwd} -e MYSQL_DATABASE={db_name} mysql
Created network and connected it to mysql:
docker network create {network_name}
docker network connect {network_name} {name_of_mysql}
And finally run the app:
docker run -d -p 80:8080 --name {name_of_project} --net {network_name} -e MYSQL_HOST={name_of_mysql} -e MYSQL_ROOT={root} -e MYSQL_PASSWORD={pwd} -e MYSQL_PORT=3307 {app_name}
It works. However in 1-2 days it stops. I checked endpoints which are not connected with mysql, it works. Also cannot connect to mysql from Intellij Idea:
Saw the logs of mysql. Something like this:
Perhaps there are some kind of ways to avoid this situation or I did something wrong? For example, should I add docker-compose instead of Dockerfile?
There are so many questions like this. However there are no answers. I decided to write step by step, maybe after it, our society will help me. I hope so...

On Windows 10, with IntelliJ Idea I built a Spring Boot application (with the help of Bootify.io).
That application connects to a Postgres Database that resides in Docker (container-postgres-1) called Bootifytwo.
With the intention of playing and practicing with GraalVM, I downloaded a Docker image from Oracle.
From the corresponding GraalVM container (container-graalvm-1) I have been able to generate the target/bootifytwo executable.
But when I try to run it, it gives me a database connection error.
I put below all the steps that I executed, and after some images.
(Note the use of a network for intercommunication between the containers; as well as the use of volumes for each of the 2 containers).
Help with resolution would be appreciated.
Copy folder C:\CODIGO\IDEA_PROJECTS\bootifytwo to C:\Volumenes-Docker\vol-graalvm-1\bootifytwo
docker network create red-postgres-graalvm-1
docker run --name contenedor-postgres-1 -p 5433:5432 --network red-postgres-graalvm-1 -v "C:\Volumenes-Docker\vol-postgres-1:/var/lib/postgresql/data" -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=password -e POSTGRES_DB=bootifytwo -d postgres:13.9-alpine3.17
docker run --name contenedor-graalvm-1 -it --network=red-postgres-graalvm-1 -v "C:\Volumenes-Docker\vol-graalvm-1:/app" container-registry.oracle.com/graalvm/community:ol8-java17-22.3.0-b1 bash
gu install native-image
cd bootifytwo
. ./mvnw native:compile -Pnative
docker start contenedor-graalvm-1
docker exec -it contenedor-graalvm-1 bash
./target/bootifytwo
The postgresql db runs in an other docker than your application. So you can't connect with localhost.
Change your setup to connect to contenedor-postgres-1
I'm trying to dockerize MySQL and Spring Boot application however whenever I try to run my docker container and connect my docker image to the network the container automatically stops running.I'm new to docker so any help well is appreciated.

C:\Users\shawn>docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
I've tried using docker starting and using docker run with a specific port but still getting the same error.
I have spring boot project with one page - Hello word!
JAR app perfectly works in a docker container.
But in my host computer docker does not want run app. Page not available.
docker ps say:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
4b34df7e3986 quality-serv "java -jar quality-s…" 21 hours ago Up 20 hours 0.0.0.0:8080->8080/tcp quality-service_con
But netstat (admin) does not find listeners on same port
App work only in the container, not in a personal computer.
I try many dif commands:
docker run -p 8080:8080 -d...
docker run --expose 9990 -p 9990:9990 -p 8080:8080 -it
docker run -d --net=host -P
docker run -it -d -p
They did not help.
Run yaml (docker-compose) with image description did not help too...
First make sure, when creating the container, the Dockerfile was exposing port 8080 EXPOSE 8080.
Then, if your application runs on port 8080, docker run -p 8080:8080 should be the command. Don't add -d by now, so you don't run detached mode and can see the logs.
Please note: I know this questions is very similar to this one however you'll note that the solution in that case was to EXPOSE the port, which I am already doing. Hence although this questions sounds similar, I think its simply a different problem altogether with similar symptoms as the other question.
Docker Version 17.12.0-ce-mac49 (21995) here. I am experimenting with Docker for the first time and have built my first Docker image. My Dockerfile is:
FROM openjdk:8
RUN mkdir /opt/myapp
ADD build/libs/myapp.jar /opt/myapp
ADD application.yml /opt/myapp
ADD logback.groovy /opt/myapp
WORKDIR /opt/myapp
EXPOSE 9200
ENTRYPOINT java -Dspring.config=. -jar myapp.jar
I build it via:
docker build -t myapp .
Everything succeeds. I then tag it as if I'm going to push it to Quay:
docker tag <imageId> quay.io/myregistry/myapp:0.1.0-SNAPSHOT
However before I publish to Quay I want to run it locally to make sure it works:
docker run -it -p 9200:9200 -d --env-file /Users/myuser/myapp-local.env --name myapp myapp
When I run this I get an indication that the container is running, and I can even see it for a few seconds via docker ps:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
f3fa8f7a4288 myapp "/bin/sh -c 'java -D…" Less than a second ago Up 7 seconds 0.0.0.0:9200->9200/tcp myapp
However after a few seconds it stops running and disappears from docker ps altogether:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
Furthermore I'm not able to SSH into the container:
docker exec -it f3fa8f7a4288 bash
Error: No such container: f3fa8f7a4288
...or see any logs/console output.
When I run myapp.jar outside of Docker (as a typical Spring Boot app, it starts up and runs beautifully without exceptions). How can I troubleshoot what is going on?
The docker logs command will show you the output a container is generating when you run it detached (with -d). This is likely to include the error message.
docker logs --tail 50 --follow --timestamps container
You can run the image in the foreground without the -d to see the output like when you run myapp.jar outside of Docker.
docker run my/image
So in this specific case:
docker run -it -p 9200:9200 --env-file /Users/myuser/myapp-local.env --name myapp myapp
If I am not mistaken, the issue you are experiencing is because you are using the shell form of ENTRYPOINT. Change it to use the exec version, as follows:
ENTRYPOINT ["java", "-Dspring.config=.", "-jar", "myapp.jar"]
The shell form will launch Java as a separate process just like a shell command. This causes PID 1 to return making Docker believe the container is finished. Using the exec form, the Java process replaces PID 1 and the container will continue running.
Is it possible to copy an existing WebSphere profile and run it on WebSphere in Docker?
I am doing some research on containerization, virtualization, etc. and am currently working with Docker. Getting WebSphere up and running on Docker is simple enough:
docker run --name wasserver -h wasserver -p 9043:9043 -p 9443:9443 -d ibmcom/websphere-traditional:install
What I'd like to do is use a profile from another WebSphere instance and run that on the Docker WebSphere. I have tried to do the following in an attempt to mount a directory that contains the profile in question, and to run same:
docker run -v /opt/WebSphere/WAS8_5/:/WASDIR --name myprofileserver -h myprofileserver -p 9043:9043 -p 9443:9443 -d ibmcom/websphere-traditional:install -e PROFILE_NAME=/WASDIR/profiles/myprofile1
The end result of this command is that the container is created, but does not run:
docker: Error response from daemon: oci runtime error: exec: "-e": executable file not found in $PATH
Perhaps there is a switch, setup, or other configuration I am missing here?
The last argument to docker run is the command you want to run inside the container (or the name of the image if you're running the default entrypoint / cmd). You just need to move your environment variable definition back in the command like this:
docker run -v /opt/WebSphere/WAS8_5/:/WASDIR --name myprofileserver -h myprofileserver -p 9043:9043 -p 9443:9443 -d -e PROFILE_NAME=/WASDIR/profiles/myprofile1 ibmcom/websphere-traditional:install
