ı installed netdata on my server and connected it to the netdata dashboard, but I noticed that I cannot see the Docker containers that are currently running on the server on the dashboard. To fix this, I updated the compose.yml file with the following volumes section:
netdata:
image: netdata/netdata
++pid:"host"
container_name: netdata
hostname: example.com # set to fqdn of host
ports:
- 19999:19999
restart: unless-stopped
cap_add:
- SYS_PTRACE
security_opt:
- apparmor:unconfined
volumes:
- netdataconfig:/etc/netdata
- netdatalib:/var/lib/netdata
- netdatacache:/var/cache/netdata
- /etc/passwd:/host/etc/passwd:ro
- /etc/group:/host/etc/group:ro
- /proc:/host/proc:ro
- /sys:/host/sys:ro
- /etc/os-release:/host/etc/os-release:ro
- /sys/fs/cgroup:/host/sys/fs/cgroup:ro
- /var/run/docker.sock:/var/run/docker.sock:ro
- /var/lib/docker/containers:/var/lib/docker/containers:ro
- /user-service:/host/user-service:ro
and then I restarted the container. However, when I checked the logs of the netdata container, I saw the following error:
2023-01-05 10:08:38: cgroup-name.sh: INFO: docker container

When I go to the bash of the netdata container, the file path /host/sys/fs/cgroup/system.slice/docker-7d6a282fefd31f1df1bs89cc234ba1sd266278a0s9f61280f8b3bb707dd79f9fb46e.scope
actually exists. But there is no file named tasks in this file path.
How can I solve this error and see every container running on the server on the dashboard?
I solved the above error by adding the pid line, but I still can't see the containers running on the server on the dashboard. netdata container logs as follows:

I saw this similar issue https://github.com/netdata/netdata/issues/11069 and the fix seemed to be to add pid: "host", check this comment
https://github.com/netdata/netdata/issues/11069#issuecomment-952228202
Can you try and see if it works?
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
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

<version>2.0.3.RELEASE</version>
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).
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
While running the image i am getting the below error:

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.
I have a springboot app that accesses my localhost:5432 postgress database
I have dockerised it and want to connect to the database from docker container
Running the container like this
docker run -p 8080:8080 risk-assesment:v1
i get the below error
