I wanted to install apache, php7, postgres12, node, java in ubuntu:18.04 base image dockerfile and wanted to show postgre data in php file. After building and running the container when I checked the process status, the port is missing. I started docker recently so I am new in this. Here is my Dockerfile

Hi I'm building a docker image that starts Mysql, Elasticsearch and application, it completes the build of the image but when I run the container it doesn't start and remains in exited status.
DOCKERFILE:

I expect at least that it goes up, I would like to understand which is the problem since on WSL ubuntu gives me this problem while on the virtual machine it works
I installed docker inside a container running on ubuntu:18.04 to run my nodejs app, I need docker installed inside this container because i need to dockerize an other small app
Her is my Dockerfile
FROM ubuntu:18.04

When the container is up, i docker exec -it app bash.
If i do a service docker start then ps ax, got this
PID TTY STAT TIME COMMAND
115 ? Z 0:00 [dockerd] <defunct>
What can i do to be able to use docker inside the container or is there a docker image not using apk but apt-get ? Because when i need to use it, i got this error :
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
First thing better to use one of the base images, either for node-image and install docker and for docker-image and installed node, instead of creating image from scratch. All you need
FROM node:buster
RUN apt-get update
RUN apt install docker.io -y
RUN docker --version
ENTRYPOINT nohup dockerd >/dev/null 2>&1 & sleep 10 && node /app/app.js
second thing, The error Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?, The reason is you are not starting the docker process in the Dockefile, and also running multiple processes in the container is not recommended, as if Docker process dies you will not know the status, you have to put one process in the background.
CMD nohup dockerd >/dev/null 2>&1 & sleep 10 && node /app/app.js
and run
docker run --privileged -it -p 8000:8000 -v /var/run/docker.sock:/var/run/docker.sock your_image
elastic search is successfully running on docker container. but i'm not able access in browser. i mapped ports correctly. but the problem is in docker container. in container elasticsearch is mapped with localhost

If you want to use docker to get an instance of Elasticsearch, you can read the following Guide:
https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html
You can also use docker images directly from elastic, if ubuntu is not a necessary base image:
https://www.docker.elastic.co/
If you want to upgrade to an ELK Stack later on, I recommend a docker volume for persistency purposes.
Installed docker tool box in windows.
Configured everything.
We have company proxy.
So to configure proxy, did the following.
Added environment variable.
set HTTP_PROXY=xx.xx.xx.xx:10015
set HTTPS_PROXY=xx.xx.xx.xx:10015
set NO_PROXY=192.168.99.100
Then created new virtual machine with following command
docker-machine create -d virtualbox --engine-env HTTP_PROXY=xx.xx.xx.xx:10015 --engine-env HTTPS_PROXY=xx.xx.xx.xx:10015 --engine-env NO_PROXY=192.168.99.100 default
And trying to build docker image with following command
docker build -t 1234567890.dkr.ecr.us-east-1.amazonaws.com/my-repository .
Here I have docker file, which has commands as following

But I am getting following error

currently I try to launch docker image on deamon with docker run -d ID (after to launch this commande: docker build -t toto .)

Thanks in advance.
In order to facilitate the usage of docker exec, make sure you run your container with a name:
docker run -d --name aname.cont ...
I don't see an entrypoint or exec directove in the Dockerfile, so do mention what you want to run when using docker run -d
(I like to add '.cont' as a naming convention, to remember that it is a container name, not an image name)
Then a docker exec aname.cont bash should work.
Check that the container is still running with a docker ps -a
When creating the container you should use the image name:
docker run -d --name my_toto toto
You cannot impose an ID when creating it. It's Docker who assigns the ID.
Then connecting
docker exec -it my_toto bash
A more quick way to do that is running directly
docker run -d -it -name my_toto toto bash
The container will still existing after you exit.
