I create a docker container with the base image ubuntu:18.04 and installed MongoDB using the shell in this container. Now, I commit and export this container and use this container image as a base image in a new container in which I need the MongoDB status as running for further process. I am using Dockerfile for both containers.
First Dockerfileis :
#getting base image ubuntu
FROM ubuntu:18.04
RUN apt-get update && apt-get install -y apt-utils wget gnupg gnupg2 curl
ENTRYPOINT ["tail", "-f", "/dev/null"]
CMD ["echo","Create base image"]
After building this Dockerfile, I accessed shell installed MongoDB, created a new db and collection, commit and export in the tar file.
Next, I import this tar file as image mongoubuntu:1.0
Now, I create another Dockerfile in which I want to run some commands which need MongoDB status as running.
The second Dockerfile is as follows:
FROM mongoubuntu:1.0
RUN apt-get update && apt-get -y install sudo && apt-get -y install curl
RUN apt-get install -y wget #install wget lib
COPY . /
RUN chmod +x /genesis.sh
RUN /genesis.sh
RUN chmod +x /wallet.sh
RUN /wallet.sh >> /config.sh
ENTRYPOINT ["tail", "-f", "/dev/null"]
CMD ["echo","Install EOS Complete"]
When I run this as docker build -t eossample:1.5 . It gets build successful. When I check the bash shell for the newly created container using this image, MongoDB is not running. If I manually start MongoDB it shows running status. Please help. How could I start MongoDB from DockerFile?

i am basically just trying to run a script into the container
I used a worpress image and built my own image out of it, thought it would keep the container up and my script will be executed but that didnt happen. My ECS cluster didnt have any running task, all i saw iin the events was service stage-fe-auto has started 1 tasks: task e83587e734c94f77. and when i opened the task details, it had Exit Code 2 and Working directory /home/app but in my Dockerfile my work directory is differen. Not sure what i did wrong
I'm trying to deploy on google cloud. So, my Dockerfile :

I made something wrong with my Dockerfile? Or is there a differente way to do the command?
#DazWilkin's comment is correct:
It's not possible to install graphics driver to Cloud Run fully managed because it doesn't expose any GPU.
You should deploy it in Cloud Run Anthos(GKE). But you'll need to configure your GKE Cluster to install your GPU, According to the documentation, you should follow the steps:
Add a GPU-enabled node pool to your GKE cluster.
In this step, you can enable Enable Virtual Workstation (NVIDIA GRID). Please choose a GPU such as NVIDIA Tesla T4, P4 or P100 to enable NVIDIA GRID.
Install NVIDIA's device drivers to the nodes.
You can now create a service that will consume GPUs and deploy the image to Cloud Run for Anthos:

How do I start the service? I'm trying to start the service with the command: service mongodb start. Isn't that correct? And what does the line:
Removing intermediate container 3d43e1d1cd96
means?
Firstly, it should be service mongod start i guess. But this is not going to solve your problem.
While using Docker, your process has to be a foreground process service mongod start will go into background & your container will exit immediately.
You should use mongod foreground process as below -
CMD ["mongod"]
Put the above CMD at the end of Dockerfile to make sure your container runs mongod.
Official Dockerfile -
https://github.com/docker-library/mongo/blob/40056ae591c1caca88ffbec2a426e4da07e02d57/3.4/Dockerfile
If you want to run multiple processes, use docker ENTRYPOINT in conjunction with supervisord or use a wrapper script.

I've been following the Hyperledger Composer tutorial. I managed to install Ubuntu 16.04 on Hyper-V on my Windows 10 Enterprise. I then started on the following pre-req installation instructions:
https://hyperledger.github.io/composer/installing/installing-prereqs.html
I ran the prereqs-ubuntu.sh script. It ran fine with no errors. I examined the logs and saw that it had successfully installed npm 5.6.0, node 8.9.4, docker 17.12.x, docker composer 1.13.x, and Python 2.7.12.
However, when I run run $ sudo npm --version
it tells me that the npm command is not found
Same with $ sudo node --version
Not found...?!
Why would that be when the log clearly shows that npm and node where successfuly installed?!
Well, what I did and managed through:
--> install nodejs and npm:
sudo snap install node --classic --channel=8
so you get the latest node8.
--> then to solve "sudo" problem with node specify the npm prefix:
npm config set prefix ~/.node_modules
add the following to .bash_profile
export PATH=$HOME/.node_modules/bin:$PATH
Now the packages will install into your user directory and no permissions will be harmend.
--> install nvm (to get exactly node 8.9 version on the next step):
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash
or
wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash
Verify:
node -v nvm
which should output 'nvm' if the installation was successful.
--> get and set node 8.9 version:
nvm install v8.9.0
nvm use 8.9.0
--> reset PATHs:
echo export PATH="$HOME/npm/bin:$PATH" >> ~/.bashrc
npm config set prefix ~/npm
echo "export NODE_PATH=$NODE_PATH:/home/$USER/npm/lib/node_modules" >> ~/.bashrc && source ~/.bashrc
--> at this stage the docker previous setup shall be destroyed:
docker kill $(docker ps -q)
docker rm $(docker ps -aq)
docker rmi $(docker images dev-* -q)
--> Installing the rest of prereqs:
sudo apt-add-repository -y ppa:git-core/ppa
sudo apt-get update
# install git
sudo apt-get install -y git
# Ensure that CA certificates are installed
sudo apt-get -y install apt-transport-https ca-certificates
# Add Docker repository key to APT keychain
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
# Update package lists
sudo apt-get update
# Verifies APT is pulling from the correct Repository
sudo apt-cache policy docker-ce
# Install Docker
echo "# Installing Docker"
sudo apt-get -y install docker-ce
# Add user account to the docker group
sudo usermod -aG docker $(whoami)
# Install docker compose
echo "# Installing Docker-Compose"
sudo curl -L "https://github.com/docker/compose/releases/download/1.13.0/docker-compose-$(uname -s)-$(uname -m)" \
-o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
# Install unzip, required to install hyperledger fabric.
sudo apt-get -y install unzip
--> now you can install Fabric dev. env. (assuming the rest of prereq components stand available):
npm install -g composer-cli
etc.
I think you need to log out and close the shell. And then restart with the new session, as the shell stores your session.
Also, after installation, the use of sudo is not recommended as mentioned on IBM hyperledger website.
My name Trang,
I have created Docker image on https://registry.hub.docker.com/u/trangunghoa/railo-mysql/
It is run ok.
Now I created Dockerfile but I can't start automatic Railo service. Please help me.
I have start by some commands at shell script:
exec /opt/railo/railo_ctl start
exec /opt/railo/railo_ctl start -D FOREGROUND
service railo_ctl restart
exec service railo_ctl restart
No command it work.
I looked inside your Dockerfile and identified the problem.
You can only use one CMD inside a Dockerfile. (if you use multiple CMD the old one will override) More info : https://docs.docker.com/reference/builder/#cmd
You need to know that Docker isn't made for running multiple process without a little bit of help. I suggest using supervisord : https://docs.docker.com/articles/using_supervisord/
You can't use RUN service inside a Dockerfile, the reason is simple the command service will be executed and start a daemon, then notify the execution was successful. The temporary container will be killed (and the daemon too) and after that the change will be committed.
What your Dockerfile should look like :
