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:
FROM ubuntu:20.04
WORKDIR \\wsl.localhost\Ubuntu\home\marco\project\multiple-docker-container\backend
COPY . .
RUN apt update
RUN apt-get update
RUN apt-get install wget -y
RUN apt install apt-transport-https ca-certificates gnupg -y
RUN wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | apt-key add -
RUN sh -c 'echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" > /etc/apt/sources.list.d/elastic-7.x.list'
RUN apt-get update -y
RUN apt-get install elasticsearch -y
RUN apt install mysql-server -y
RUN apt install npm -y
RUN npm install
RUN npm install nodemon
RUN apt install nodejs -y
EXPOSE 3306
EXPOSE 9200
EXPOSE 5000
COPY entrypoint.sh /bin/entrypoint.sh
RUN chmod +x /bin/entrypoint.sh
ENTRYPOINT ["/bin/entrypoint.sh"]
ENTRYPOINT.SH
#!/bin/sh
service elasticsearch start
service elasticsearch enable
service mysql start
npm start
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'm new to docker and I'd like to understand the reason for this error, I'm creating a dockerfile where to start Elasticsearch, Mysql and the application, when I build it gives me this error "Error response from daemon: dockerfile parse error line 38: instruction unknown: ENTRYPOINT["/BIN/ENTRYPOINT.SH"]"
Dockerfile

What could be the problem? I'm running this on an ubuntu terminal
In your question you wrote ENTRYPOINT["/BIN/ENTRYPOINT.SH"], in the Dockerfile I see ENTRYPOINT ["/BIN/ENTRYPOINT.SH"].
If your are talking about ENTRYPOINT["/BIN/ENTRYPOINT.SH"] the error is the missing space before the opening square bracket.
The previous answer is not very helpful.
I was getting the same error, but I wasn't missing a space and my error was not missing the space.
Turns out, there were newlines between directives in the Dockerfile.
So clearly spacing matters a little more than it should. 😉
I am new to dokers. I need jenkins and jupyter notebook in the same container. I have written the following Dockerfile but I can't access localhost:8888 or 8080 or 50000 when I run this image. However, these ports work very well when I run the official jenkins image. So, I don't know where I am making the mistake in my Dockerfile.

I want to install rclone on a docker image in heroku to able to use Rclone with python telegram bot
I made a heroku.yml file
build:
docker:
worker: Dockerfile
run:
worker: bash start.sh
And start.sh as
python3 -m bot
And Dockerfile as
FROM ubuntu:18.04
WORKDIR /usr/src/app
RUN docker pull rclone/rclone:latest
RUN docker run rclone/rclone:latest version
RUN chmod 777 /usr/src/app

ENV LC_ALL en_US.UTF-8

I get error The command '/bin/sh -c docker pull rclone/rclone:latest' returned a non-zero code: 127 in the git bash CLI
What Am I doing wrong? Or what is the procedure?
Thanks in advance!

Based on this answer
You can try this, also don't try to use docker commands inside a Dockerfile.
I am trying to use a node agent container in Jenkins to run npm instructions on it. So that, I am creating a Dockerfile to get a valid image with ssh and nodejs. The executor runs fine, but when I use npm it says that it doesn't know the command.
The same problem happens when (after building the dockerfile) I do docker exec -it af5451297d85 bash and after that, inside the container, I try to do npm --v (for example).
# This Dockerfile is used to build an image containing an node jenkins agent

# Install NGINX to test.
RUN apt-get install nginx -y
# Prepare container for ssh
RUN mkdir /var/run/sshd && adduser --quiet jenkins && echo "jenkins:jenkins" | chpasswd
RUN npm install
ENV CI=true
EXPOSE 22
CMD ["/usr/sbin/sshd", "-D"]
I would like to run npm instructions like npm install, npm publish, ... to manage my project in a jenkinsfile. Could anyone help?
Thanks
I have already solved the problem (after two weeks haha).

You don't need to install npm from the ubuntu distribution with:
RUN apt-get install -y npm
because it's already installed by the nodejs package from nodesource. You can check it with:
dpkg -L nodejs | grep "/usr/bin/npm"
