What do you want us to build?

.NET Core 7 was officially released on November 8th.

Is this request specific to an Elastic Beanstalk platform?
If so, which one(s)?

Looking to be able to deploy new .NET Core applications to AWS - unable to do so currently.

This is a massive blocker for an upgrade we want to do, I would have hoped to see Beanstalk stay up to date with the latest run times.

[chrispaynter]

Hmmm, actually I updated to this - 64bit Amazon Linux 2 v2.4.1 running .NET Core

Looks like it does support .NET 7, however they website doesn't list it in the Frameworks section.

https://docs.aws.amazon.com/elasticbeanstalk/latest/platforms/platform-history-dotnetlinux.html

[chrispaynter]

Ignore that I must have read my logs wrong. .NET 7 not supported. This is something I'd consider rather urgent for AWS to resolve.

Does anyone have a solution?

Trying to deploy a .net 7 application to Elastic Beanstalk runnion on Amazon Linux 2

If you build your project as Self-Contained, you can run .NET 7 on AWS Elastic Beanstalk.

To do this, check the box: Build self-contained deployment bundle.

[bytecod3r]

is there any development roadmap to include dotnet 7 on the elasticbeans?

I've got a CI build using the command line (dotnet restore/build/publish). Do you know what the equivalent runtime ID (or other args I should pass to get the equivalent of the Amazon Publish UI?

I've tried with the folowing, but I'm not sure there is a probleme with my arguments or if its something else that isn't working.

dotnet publish "my.csproj" -c Release -o publish --runtime linux-x64

@AndrewMutation for build pipelines you need to install the latest .NET build tools:

  install:
    commands:
      - curl -sSL https://dot.net/v1/dotnet-install.sh | bash /dev/stdin --channel ST

My build isn't on AWS, but that may help someone else :)

It seems like my problem is probably the glibc version on arm64 that is discussed here: dotnet/runtime#80866

When I installed (Edit: on amazon linux in EB) v7 with dotnet-install.sh, I got the error they describe: `GLIBC_2.27' not found

[AndrewMutation]

The issue seems to be resolved for me with the release of 7.0.4
I copied dotnet-install.sh onto the machine and ran it with channel 7.0

dotnet-install.sh --channel 7.0 --runtime aspnetcore -InstallDir /usr/local/dotnet/

[RedHot17]

please hurry with this

We are nearing the one year anniversary of DotNet 7, any news when NET Core running on 64bit Amazon Linux 2 will be upgraded to .net 7?

[edvanr]

Yeah this is really holding us back. There are so many EF core features in dotnet 7 that we need and it is preventing us from upgrading everything. Very close to ditching beanstalk if this doesn't happen soon...

I solved this problem using ebextensions.

Created .ebextensions folder in the root of the project and dotnet.config file in it and added dotnet install command.
After deployment, this command run first on elastic beanstalk environment.

dotnet.config file

commands:
  01_dotnet_install:
    # install .net 7.0
    command: 'curl -sSL https://dot.net/v1/dotnet-install.sh | bash /dev/stdin --channel 7.0 --runtime aspnetcore -InstallDir /usr/local/dotnet/'

I thought Amazon was pretty public about only officially supporting LTS versions of .Net on their platforms - which is 6.0. For things we want to run the latest/greatest on, we deploy to either Lambda with custom runtimes/layers or EC2 directly. For things we want to stick with LTS on, we deploy use the services that are managed more by AWS. These are things you need to take into consideration when you're designing your apps and deciding what your deployment platform will be.

[matheuscschenfeld]

I resolved this by using a Docker image in ECR and configuring the service in ECS

[slavik93]

Based on https://docs.aws.amazon.com/elasticbeanstalk/latest/platforms/platform-history-dotnetlinux.html there are no default elastic beanstalk platforms that support .NET 7.
As a workaround, you can create a default Elastic Beanstalk platform, .NET Core Linux, which supports .NET 6.
Then, connect to the EC2 instance and install .NET 7 SDK by the following commands:
sudo rpm -Uvh https://packages.microsoft.com/config/rhel/7/packages-microsoft-prod.rpm
sudo yum install -y dotnet-sdk-7.0

[aswanevelder]

According to @scionwest's comment on STS not supported by AWS, then .Net 8, set to be released between November 14-16, will be the Long-Term Support (LTS) version. I guess then as a result, EB will skip .Net 7, which was a Short-Term Support (STS) release. It's uncertain how long AWS will take to implement this upgrade, but there is optimism for the future.

[slavik93]

As an additional option, to deploy a project with a greater .NET SDK than 6 is to add a configuration file in the uploaded Zip for Elastic Beanstalk to install the dependencies during deployment.
Directory Location: You create a directory named .ebextensions at the root of your application source code. Inside this directory, you place configuration files(e.g. 01_install_dotnet_7.config) in YAML or JSON format.
This is the file content to install .NET 7 SDK:
commands:
01_install_dotnet_7:
command: |
sudo rpm -Uvh https://packages.microsoft.com/config/rhel/7/packages-microsoft-prod.rpm
sudo yum install -y dotnet-sdk-7.0

If you build your project as Self-Contained, you can run .NET 7 on AWS Elastic Beanstalk.

To do this, check the box: Build self-contained deployment bundle.

this works for me; using dotnet publish project -c Release -o build --self-contained true

Superseded by .NET 8, which is LTS. Track #311 for .NET 8 on Linux
