Chapter 2. Known issues

NodeJS is no longer included in the .NET 8.0 SDK image.

For information on how to port an application that depends on Node.js from an earlier .NET version to the .NET 8.0 image, see the Porting web applications with NodeJS front-ends to build with .NET 8.0 UBI images Knowledgebase solution.

In .NET 8.0, you can no longer specify the command and its arguments to run in a container as a single string. You need to pass the arguments as separate strings. The new syntax also works for the earlier .NET versions.

For example, instead of podman run registry.access.redhat.com/ubi8/dotnet-70 “echo hello”, use podman run registry.access.redhat.com/ubi8/dotnet-80 echo hello.

The dnf command is not available.

To reduce image size, .NET 8.0 container images use the ubi-minimal base image instead of the ubi base image. The ubi-minimal image uses the microdnf command as its package manager instead of the dnf command.

If your Dockerfiles/Containerfiles use the dnf command, you must change them to use the microdnf command instead.

For more information about the microdnf command, please see the microdnf man page.
