Ubuntu docker11/12/2023 ![]() ![]() Of course any files from the /usr/src/project directory will be modified on your local hard drive as this is mounted from it. Just remember that any file you modify from inside the container will not be preserved and next time you start back to default state. Because bash does not exit and you have the -it parameter, you will be at the container's prompt where you can do whatever you want. This would create the container from the myimage image, and run bash. If you wanted to just have access to some shell so you could manually run make or other commands in a ad-hoc fashion, you could also do this: docker run -rm -it -v $(pwd):/usr/src/project myimage /bin/bash The -it parameters mean interactive and tty. The -rm parameter tells Docker to not keep the container around once it finish running. Run the make command inside the container and then exit. What will happen if you ran the docker command line above is that it will create a container from the image named myimage (build command shown earlier), mount the current directory you are in as /usr/src/project inside the new container. This would require a line in your Dockerfile to make the working dir /usr/src/project: WORKDIR /usr/src/project ![]() Let's say you are building with the command make, you could do this: docker run -rm -it -v $(pwd):/usr/src/project myimage make I don't know what OS you run on your workstation or server so I will refer to this post for more information: To set the user password, add -p '(openssl passwd -1 ubuntu)' to useradd command. You would want to mount your directory with the code inside the container when you run it. see: Understanding how uid and gid work in Docker containers-p, -password PASSWORD Encrypted password of the new account (e.g. So you seem to be making a container to build some code. ![]() It is not really necessary as you don't manage the network from within the container. Ifconfig does not work because the binary is not in the image. Then you can build your image: docker build -t myimage. Then you will need to actually run something. To install packages, you probably want to do something like this: FROM ubuntu:16.04Īpt-get -y install build-essential autoconf libtool & \Īpt-get install -y python-setuptools python-dev python3-dev & \Īpt-get install -y python-pip python3-pip & \Īpt-get install -y python-virtualenv unixodbc-dev libffi-dev git & \ Each line/command result in one more layer. The image would (normally but not mandatory) have a CMD command or ENTRYPOINT command to run something.Įach line in a Dockerfile is a command instructing Docker on how to create the image. Then you add your own additional layers, adding binaries and files that are necessary to run your program / process. When you create a Docker image with FROM ubuntu you are starting your image with some pre-created layers that brings in some parts of a standard file system and packages you would find on a Ubuntu server. The container uses the same kernel as what is on the host. It is for running a single process in a contained (isolated) environment. There are resemblances but they aren't the same and frankly, not really similar.ĭocker is not, really, for running an OS. The first mistake is to think that a Docker image/container is similar to a virtual machine. RUN sudo apt-get install -y python-virtualenv unixodbc-dev libffi-dev git RUN sudo apt-get install -y python-pip python3-pip RUN sudo apt-get install -y python-setuptools python-dev python3-dev RUN sudo apt-get install -y build-essential autoconf libtool One thing I'm confused with is why I can't get ip address when I run ifconfig on my Ubuntu server running on Docker? Am I going to a right direction for running Ubuntu on Docker with the below way? This is because Ubuntu runs the containers at scale, it is fast, secure, and open-source, powering millions of machines worldwide. So, I'm trying to run our project on Ubuntu on Docker with the below Dockerfile and docker-compose.yml, but I can't find many resources like how to run Ubuntu on Docker. Ubuntu is the number one platform for managing Docker or Kubernetes containers. We decided to solve the hassle with Docker. As new developers come join our project, it is a big hassle for us help them create a new Ubuntu server on VirtualBox and install all the dependencies just to start the project every time. Installing Ubuntu From your CLI run the following command: docker pull ubuntu This will download the latest official Ubuntu image available. └─2398 /usr/bin/dockerd -H fd:// -containerd=/run/containerd/containerd.sockįeb 28 06:54:43 ubuntu dockerd: time="T06:54:43.547798752Z" level=info msg="scheme \"unix\" not registered, fallback to default scheme" module=grpcįeb 28 06:54:43 ubuntu dockerd: time="T06:54:43.My team has been developing our project on Ubuntu 16.04 server running on VirtualBox.
