Add Ubuntu Chiseled extra images for .NET Runtime and ASP.NET Core

[lbussell]

There is a desire to use globalization libraries in combination with framework-dependent deployments on Ubuntu Chiseled:

• Reconsider supporting aspnet and runtime chiseled-aot and chiseled-extra for Ubuntu #5014
• Announcement: New approach for differentiating .NET 8+ images #4821 (comment)

Changes:

• Add Ubuntu Chiseled "extra" images for .NET 6.0 and 7.0 #5042
• Add CBL Mariner/Azure Linux extra images for .NET Runtime and ASP.NET Core #5262

Example image flavors:

• mcr.microsoft.com/dotnet/aspnet:8.0-jammy-chiseled-extra
• mcr.microsoft.com/dotnet/aspnet:8.0-jammy-chiseled-composite-extra
• mcr.microsoft.com/dotnet/nightly/aspnet:8.0-cbl-mariner2.0-distroless-extra
• mcr.microsoft.com/dotnet/nightly/aspnet:8.0-cbl-mariner2.0-distroless-composite-extra

Just wanting GH to reference the related issues for discoverability.

[Kerwood]

Yes please.. We have a lot of .Net apps in our org. depending on the tzdata package as well, which is the reason we cannot change to the chiseled image.

[lbussell]

[Triage] As mentioned in #5014 (comment), these images are available now in the nightly aspnet and nightly runtime repos. They will be officially supported with the next .NET servicing release (Jan).

[mantasaudickas]

If I get it right: alpine3.18-extra (nightly) includes these packages:

• icu-data-full
• icu-libs
• tzdata

and chiseled-extra:

• libicu70_libs
• tzdata_zoneinfo
• tzdata_zoneinfo-icu

Are these covering the same ICU/Timezone aspects in .NET apps?

[lbussell]

Yes, you can check the packages installed in the Dockerfiles themselves:

dotnet-docker/src/runtime-deps/8.0/alpine3.18-extra/amd64/Dockerfile

Lines 11 to 21 in da5a045

	RUN apk add --upgrade --no-cache \
	ca-certificates-bundle \
	\
	# .NET dependencies
	icu-data-full \
	icu-libs \
	libgcc \
	libssl3 \
	libstdc++ \
	tzdata \
	zlib

dotnet-docker/src/runtime-deps/8.0/jammy-chiseled-extra/amd64/Dockerfile

Lines 27 to 39 in da5a045

	&& chisel-wrapper --generate-dpkg-status /rootfs/var/lib/dpkg/status -- \
	--release ubuntu-22.04 --root /rootfs \
	base-files_base \
	base-files_release-info \
	ca-certificates_data \
	libc6_libs \
	libgcc-s1_libs \
	libicu70_libs \
	libssl3_libs \
	libstdc++6_libs \
	tzdata_zoneinfo \
	tzdata_zoneinfo-icu \
	zlib1g_libs

The new extra images for Chiseled Runtime and ASP.NET Core are based on this image. You can inspect the contents of each image in the distros' respective package repositories. For example:

• Alpine 3.18 icu-libs
• Ubuntu 22.04 Chiseled libicu70_libs

We aspire for these images be functionally equivalent for running .NET apps (aside from the lack of package manager and shell in Ubuntu Chiseled). If you find that they aren't, please file an issue.

[garrettsutula]

Would it be possible to make the same for earlier versions of .NET e.g. 6.0?

Helpful for the same reasons really - I expect to update projects on older versions of the .NET framework but don't have that done yet.

Sorry, but for me still not clear.. I get that from functionality point of view these will be equivalent.. but what about data?
In alpine-extra we have icu-data-full... so which package in chiseled-extra is equivalent to it?

Hi,
Sorry for asking such stupid question, but when do you plan to release image?

[MichaelSimons]

Hi, Sorry for asking such stupid question, but when do you plan to release image?

They will be released today - See #5014 (comment).

[lbussell]

These images are now available in the main aspnet and runtime repos. Please see the announcement: Ubuntu Chiseled runtime and aspnet images are now available in the extra variant (#5092).

Looking at using the '-jammy-chiseled-extra' package for our deployments, currently we are using the bloated '-jammy' so we can set the timezone within the dockerfile. would the new -extra package rely soly upon the regional settings as configured in .net?
