ASP.NET Core Docker error: An assembly specified in the application dependencies manifest (MyApp.deps.json) was not found

Yesterday I had some trouble to get my docker build up and running. However after I succeeded and tried to run my container using docker-compose up, I got the following error message in the container log:

An assembly specified in the application dependencies manifest (MyApp.deps.json) was not found:

package: 'Microsoft.AspNetCore.Antiforgery', version: '2.0.1'

path: 'lib/netstandard2.0/Microsoft.AspNetCore.Antiforgery.dll'

This assembly was expected to be in the local runtime store as the application was published using the following target manifest files:

aspnetcore-store-2.0.3.xml

The problem is caused by the fact that the ASP.NET Core SDK version on the build image(2.0.0) and the referenced version in my project(2.0.3) didn’t match. Easiest solution I could find was resetting the package reference to 2.0.0 in my csproj file:

<Project Sdk="Microsoft.NET.Sdk.Web">

<PropertyGroup>

    <TargetFramework>netcoreapp2.0</TargetFramework>

    <DockerComposeProjectPath>..\docker-compose.dcproj</DockerComposeProjectPath>

</PropertyGroup>

<ItemGroup>

    <PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.0" />

</ItemGroup>

<ItemGroup>

    <DotNetCliToolReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="2.0.2" />

</ItemGroup>

</Project>

After doing that I had to stop and delete the previously created container and build and run a new instance using docker-compose build and docker-compose up.

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t
