Docker not connecting to port - docker

When I run the command:
docker run -d -p 8080:3100 username/sb-dockerized
and go to localhost:8080, it doesn't connect. Says "This page isn't working"
In my Dockerfile I am exposing port 3100
EXPOSE 3100

Any idea of what could be going wrong?

In your Dockerfile, EXPOSE 8080 because your spring-boot app is listening to that port inside your container. While running, run with docker run -d -p <<the port you want to hit in the url>>:8080 username/sb-dockerized and then access http://localhost:<<the port you want to hit in the url>>

From your browser navigate to http://<hostIP>:8080

503 status in case of starting spring configuration server via docker-compose

I've created demo configuration server using spring boot. It works fine.
$ curl GET http://localhost:9090/actuator/health
curl: (6) Could not resolve host: GET
{"status":"UP"}%
I use as parent project
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.3.RELEASE</version>
dependencies:
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-server</artifactId>
<version>2.0.0.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
Next step is to wrap the service via docker. Dockerfile is:
FROM java:8-jre
VOLUME /tmp
ADD target/*.jar app.jar
ENV JAVA_OPTS="-XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode"
ENTRYPOINT java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar
EXPOSE 9090
Creating independent docker image and starting container it works like expected:
$ docker build .
>> ... <imageName>
$ docker run -p 9090:9090 <imageName>
Creating docker-compose.yml:
version: '3.3'
services:
config-server:
build: config-server
ports:
- "9090:9090"
expose:
- "9090"
networks:
- "my-network"
networks:
my-network:
Starting and checking result:
$ docker-compose up -d
$ curl GET http://localhost:9090/actuator/health
curl: (6) Could not resolve host: GET
{"status":"DOWN"}%
Log trace looks ok:

Is any idea how to fix health status of the service that is started in docker-compose?
Every time I started containers, they were created successfully. They were dropped also successfully directly, before starting new ones. Last time I used instruction:
docker-compose down
to drop containers managed by docker-compose in automatic way.
That seems clear.
...But! The issue was in already created images. And images was not updated. To confirm my assumption I dropped correspond image and every thing was fixed. To make it in automatic way I've detected docker-compose additional useful flags and I use now:
docker-compose down --rmi local
--rmi means drop all images on which were based containers.
local Remove only images that don't have a custom tag set by the image field (it is non internet loaded images for usual cases).

Error while running docker image for springboot project

I have a springboot project with spring data jpa
My application.properties looks like
spring.datasource.url=jdbc:mysql://localhost:3306/db1
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
It runs without an error when i run with maven "mvn spring-boot:run"
I created a docker image for the project and tried to run it
docker run springbootdemo //springbootdemo is the docker image name

Any help would be appreciated. Thanks in advance !!
When you are inside of a Docker container, the localhost resolves to container IP address. But your Database is not in your application Docker container.
So you should change spring.datasource.url configuration to a URL that is real database IP address accessible from your application Docker container. Change the localhost in spring.datasource.url to Docker host IP address or your LAN IP address.
Also I think it's better that you specify an environment variable in your Docker file that points to the Database IP address and use that in your configuration properties.

Docker - Spring Boot JPA(inside Docker) + MySQL(outside Docker)

I am new to Docker. Trying to understand the concepts with a small example.
Currently, I have SpringBoot REST JPA(8080 port) + MySQL server (3306 port). Working perfectly fine(without docker).
I want to deploy Spring Boot REST JPA in a Docker container and MySQL should remain outside Docker engine, it should remain running in same localhost:3306 port.
As a beginning, created a simple HelloWorld app without JPA, able to containerize. And able to get the output from RESTful URL. Now the tricky part started MySQL server 3306 and added Database credentials to Hello World code, built and run the docker once again. I guess it's unable to find localhost: 3306? Please suggest how to make this work? I don't want to containerize MySQL server.
SpringBoot application.properties file:
spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase?useSSL=false
spring.datasource.username=root
spring.datasource.password=password

Thanks.
A docker ontainer is commonly run in a separate network namespace. That means that e.g. localhost refers to the container for processes running in it.
To resolve the issue you need will need to update the connection string:
spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase?useSSL=false
So that it yields a valid connection. Additionally there are several networking options that you can use for various scenarios. https://docs.docker.com/network/
If this is only intended for local development the simplest might be to use a host network, but this is probably not the setup you want in a production environment.

ECS Agent starting Docker container doesn't complete. Manual start successful

I followed the ECS Getting Started tutorial but the ECS Agent isn't getting the container started. When I start the image manually on the same instance it starts fine.
The image is a Spring Boot web application with a single endpoint on / that returns the string "Hello world!!". The container runs fine locally, and also runs fine on a CentOS EC2 instance I've created. The endpoint is available publicly when I run the docker image on the CentOS EC2 instance.
The ECS Instance has security groups created by the wizard and has port 80 open. I added port 22 for SSH access.
When I SSH into the ECS instance to see the Docker logs for my container, and it looks like it's hanging during the entrypoint execution.
Here are the Docker logs for the hanging instance:

At first it seems like an application error in my container image, but when I stop the docker process and run the same image manually, the output is as expected and I can reach my endpoint from outside the instance as expected.

The memory key in the Task Definition JSON imposes a hard memory limit on the container. When a container tries to exceed that limit, the Docker daemon is supposed to kill it.
I'm not sure whether this can cause your container to get "stuck", however that's the only important difference I see between how your container runs when ECS runs it and how it runs from the command line.
So, I would try to set the memory value to at least 300, or use the memoryReservation key instead which imposes a soft memory limit.
More information on the difference between hard and soft memory limits can be found in the official ECS documentation.
