![]() You can use Podman to run containers in a rootless environment that increases security. devcontainer directory to the source code repository so that other developers can take advantage of the container definition for their development efforts.ĭeveloping inside a container helps prevent conflicts between different projects by keeping the dependencies and code for each separate. (Be sure to add the vscode user to the container image via the Dockerfile.) For example, if you're doing Ansible development, you could use Quay.io's Ansible Toolset. Modify the Dockerfile to install additional software (e.g., required Python modules).Now that you've completed the basic setup and configuration, you can further enhance the configuration's usefulness. VS Code can even bring your SSH keys and Git configuration into the container so that committing code will work just like it does when editing outside the container. Now, you can proceed with development within the container. Files created or edited within the container will be reflected in the filesystem outside the container with the proper user permissions applied to the files. Once the container build completes, the project will open inside the container. The devcontainer.json file should look like this (don't forget the commas at the end of the lines, as indicated): ![]() These options tell VS Code to mount the Workspace with the proper SELinux context, create a user namespace that maps your UID and GID to the same values inside the container, and use vscode as your username inside the container. To run the development container as a rootless container, modify the devcontainer.json file by adding the following lines to the end of it: "workspaceMount": "source=$,target=/workspace,type=bind,Z", In addition to the obvious security benefits, one of the other reasons to run a container as rootless is that all the files created in the project folder will be owned by the correct user ID (UID) outside the container. VS Code automatically opens the devcontainer.json file so that you can customize it. devcontainer folder containing files named devcontainer.json and Dockerfile. In the text box, replace docker with podman. In the dropdown menu that appears, select Remote - Containers, and scroll down to find the Remote > Containers: Docker Path option. Within VS Code, navigate to File > Preferences > Settings and click the > icon next to Extensions. Next, install Podman and its supporting packages with a simple dnf install command: $ sudo dnf install -y podmanĪfter you install Podman, configure VS Code to use the Podman executable (instead of Docker) for interacting with the container. (See the VS Code website for more information on installing.) Initial configurationīefore continuing, ensure your Red Hat Enterprise Linux (RHEL) or Fedora workstation is updated with the latest errata and that VS Code and the Remote - Containers extension are installed. This article walks you through the setup to develop inside a rootless container using Podman with VS Code and the Remote - Containers extension. This container definition can be checked into the source code repository along with the application code, which allows all developers to use the same definition to build and develop within a container.īy default, the Remote - Containers extension uses Docker to build and run the container, but it is easy to use Podman for container runtimes, and it enables using rootless containers. VS Code's Remote - Containers extension enables you to define a container, use that definition to build a container, and develop inside the container. eBook: Kubernetes patterns for designing cloud-native apps.Kubernetes Operators: Automating the container orchestration platform.An introduction to container terminology.
