Docker tools for .NET projects

Add Docker support to a .NET project

When you first open a project where Docker support is already set up (there is Dockerfile in the project directory and there is DockerfileFile project property or there is Docker profile in the launchSettings.json file), JetBrains Rider will create a Dockerfile run configuration according to project properties. You can then use this configuration to run and debug the project.

To enable Docker support for an existing project, right-click it in the Solution Explorer and choose Add | Dockerfile. In the dialog that opens, choose a container type: Linux or Windows. This will generate Dockerfile with necessary instructions and .dockerignore file as well as a new run configuration.

If you are creating a new project from scratch, you can enable Docker support in this project right from the start by choosing one of the container types in the Docker Support selector:

Add Docker Compose support to a .NET project

When you first open a solution where Docker Compose support is already set up (there is .dcproj file in the project), JetBrains Rider will create a Docker Compose run configuration according to the project properties.

Note that Docker Compose configuration files (docker-compose.yml, and docker-compose.override.yml) should be in the same directory as .dcproj file. If these configuration files have different names or are located in a different directory, use the DockerComposeBaseFilePath property in the .dcproj file to specify the correct path. For example:

• my-custom-compose: JetBrains Rider will search for my-custom-compose.yml and my-custom-compose.override.yml files in the project directory;

• ..\my-custom-compose: JetBrains Rider will search for the same files but in the parent directory.

You can specify additional compose files using the AdditionalComposeFilePaths property. It is also possible to set up a custom Docker Compose project name with the DockerComposeProjectName property. To disable the Fast mode, set the DockerDevelopmentMode property to Regular.

If no Docker Compose support is configured in the project, you can enable it by right-clicking your project in the Solution Explorer and choosing Add | Docker Compose File. In the dialog that opens, choose a container type, Linux or Windows. This will generate a docker-compose.yml file and the corresponding run configuration. If this file already exists, it will be extended by the current project. If the current project doesn't have a Dockerfile, it will be generated too.

Project settings for Docker support

When JetBrains Rider generates a Docker run configuration for your project, it will use the solution folder path. You can customize this behavior using the DockerfileContext property in your project file. There are also several additional project properties that will affect the created run configuration.

Some of MSBuild Container Tools properties in the project file (.csproj):

• ContainerDevelopmentMode

• DockerfileBuildArguments

• DockerfileRunArguments

• DockerfileTag

• DockerfileContext

• ContainerDevelopmentMode

Some of Container Tools launch settings profile (launchSettings.json):

• httpPort

• sslPort
