Run Docker In Windows 10



Description I am using Docker version 1.12.5 on Windows 10 via Hyper-V and want to use container executables as commands in the current path. I built a Docker image that is running fine, but I hav. MongoDB document databases provide high availability and easy scalability. The official Windows IoT Core base image for containers. The Docker menu in the top status bar indicates that Docker Desktop is running, and accessible from a terminal. If you’ve just installed the app, Docker Desktop launches the onboarding tutorial. The tutorial includes a simple exercise to build an example Docker image, run it as a container, push and save the image to Docker Hub. On Windows 10, after your docker container is started, you can run docker-machine ip in command line (cmd or Docker QuickStart Terminal, etc) to get the ip address of your docker container. This ip address is usually, 192.168.99.100.

I admit it, I was not a friend of Oracle databases running in Docker containers for a long time. My database systems for testing and demo purposes were all running in VMware, Virtual Box or in the Oracle Cloud. But I have used the Windows Subsystem for Linux since beginning, to work with the Oracle Oracle Cloud Infrastructure CLI, Git Integration etc.. And what I really like is the WSL extension for Visual Studio Code which gives me to chance, to edit Ansible Vault files in Windows without any additional Linux based VM running.

With the update of the existing Windows Subsystem for Linux (WSL) architecture to version 2, the Docker Desktop for Windows is now fully integrated and able to run Docker container in WSL as a lightweight VM. Now it’s time to change my mind, why not use Docker to try out new Oracle features, do some development stuff and more?

What to we need to run Oracle databases in WSL 2 Docker Containers?

  1. WSL 2
  2. Docker Desktop for Windows
  3. Docker images with an Oracle Database – I may use the images (oehrlis/docker) from my workmate Stefan Oehrli (oradba.ch)- merci vöumou

This blog post shows you how to setup WSL 2 to run Docker images. Sure, you can use the Oracle provided Docker images or self created images too. But I have verified the Oracle repository today, the Dockerfile version is 19.3.0. And I don’t have the passion, to create new Dockerfiles for example to run 19.8 and download additional RU software.

Installing Windows Subsystem 2 for Linux

Enable Windows Subsystem for Linux basic Functionality

Start Windows PowerShell as Administrator and enable WSL.

dism.exe/online/enable-feature/featurename:VirtualMachinePlatform/all/norestart

Restart the Windows machine. Now wsl.exe is available as command in Power Shell.

Set WSL 2 as default when installing Linux distributions from Microsoft Store like Ubuntu and SLES.

Getting Windows 10 ready for Docker

  • https://code.visualstudio.com/blogs/2020/03/02/docker-in-wsl2

Install Docker Desktop for Windows

Run the Docker Desktop Installer executable. Let the checkboxes activated.

Two minutes later.

Start Docker and verify the Availability

After starting the Docker Desktop, you get a notification that Docker is starting. Docker is recognising that WSL is installed.

Docker is now ready to use.

Run Docker In Windows 10

Open a new PowerShell as Administrator and verify if docker and docker-compose are available.

Install Git

Link: https://git-scm.com/download/win

We use Git to checkout the Oracle docker containers later. There are several Git clients for Windows available. I use the one from git-scm.com. Just run the executable. After the successful installation, verify Git availability in PowerShell.

Go for the Oracle Database

Startup the Oracle Docker Image

Before cloning of the Git repository, I created a new directory in my Workplace folder.

Clone Docker Image Repository

The content of my cloned directory Oracle Database 19.0.0.0.

We use Docker Compose here, this makes it very easy to handle networking stuff like port forwarding. Example content of the docker-compose.yml file. In this case, I have not configured the Docker Volume Base, the files for the container are created in a subfolder of the clone directory.
