dock-gen
dock-gen is a very simple .NET tool designed to generate Dockerfiles for one or multiple projects in a solution based on dependencies in a predictable way each time.
Please note, dock-gen is still in its early stages, some features may not be stable.
Since .NET 7, dotnet comes with a built-in feature to publish app as container image. If you don't need to generate Dockerfiles, you can use the
dotnet publishcommand to publish your application as container. For more information, see the official documentation. dock-gen is designed to provide more control over the Dockerfile generation process but it may not be suitable for all use cases.
Installation
To install dock-gen, you can use the dotnet tool install command:
- global installation:
dotnet tool install --global dockgen
- local installation: (optional) if you don't have a manifest file for your project, create one:
dotnet new tool-manifest
Add the tool to the manifest file:
dotnet tool install dockgen
Usage
You can use dock-gen with the generate command. This command takes two optional parameters:
-sor--solution: To specify the solution file.-por--project: To specify the project file.
Here is an example of how to use the generate command:
dotnet dockgen generate -s MySolution.sln -p MyProject.csproj
If no solution or project file is specified, dock-gen will try to find a solution file in the current directory.
Features
- Generate Dockerfile: Generate a Dockerfile for a single or multiple projects at once
- Multi-Stage Build: Generate a multi-stage Dockerfile for a project
- Central Package/Build Management: dock-gen supports CPM/CBM in your project
