PackagingTools can emit a helper script for reproducing Linux packaging runs inside Docker containers. This keeps build environments consistent across distributions.
Set the following properties when invoking the CLI/SDK:
--property linux.container.image=mcr.microsoft.com/dotnet/sdk:7.0 \
--property linux.container.projectPath=projects/sample.json
Additional optional properties:
| Property | Description |
|---|---|
linux.container.output |
Override output folder inside the container (defaults to request output). |
linux.container.projectPath |
Path to the project file inside the mounted workspace (defaults to <project>.json). |
When the pipeline completes successfully, container-build.sh is written to the packaging output directory. The script mounts the current working directory into /workspace inside the chosen image and reruns packagingtools pack with the same formats, configuration, and properties.
./container-build.sh
The script assumes Docker is installed and the packagingtools CLI is available inside the container image. Custom images can preinstall prerequisites such as WiX, fpm, or custom toolchains.
