The dev containers for dotnet published by Microsoft do not have all the prerequisites for Rider or any other JetBrains IDE. It is missing the Java Runtime and sshd.
The fix is simple enough. We can use features to run apt and install the package. To our devcontainer.json, we add
"features": {
"ghcr.io/rocker-org/devcontainer-features/apt-packages:1": {
"packages": "openssh-server,openjdk-25-jre"
}
An complete example devcontainer.json:
{
"name": "Northwind Trading Post",
"image": "mcr.microsoft.com/devcontainers/dotnet:dev-10.0-noble",
"features": {
"ghcr.io/rocker-org/devcontainer-features/apt-packages:1": {
"packages": "openssh-server,openjdk-25-jre"
}
}
}
Cheers!
