dockertest | Write better integration tests! Dockertest helps you boot up ephermal docker images for your Go test | Testing library

Use corresponding ARM .NET runtime image for your RaspberryPI in your Dockerfile

For example, this one should work

There's two JVM's to consider here

1. Gradle's JVM
2. The Application's JVM

When you pass a "-D" parameter to Gradle you are setting a system property in Gradle's JVM which is not the same JVM that runs your application

You haven't said how you are running your application yet.

• Are you running the application in a test case?
• Are you running it via the "run" task from the application plugin?

If you wanted to set the property during tests you'd do something like

Those logs are internal to the container. It's not clear how you've told your server to run on 5150, but EXPOSE doesn't change the code behavior, and there appears to be this ASPNETCORE_URLS environment variable which controls the server binding, and you've not overridden this anywhere

If you simply want to use localhost:5150, with no other changes, you would need to use 5150:80 as your compose ports definition

Please have a look at the sample Dockerfile for .NET Core applications in the Docker documentation.

In your Dockerfile you're missing the build (and publish part), which one normally wants to be done as part of the Docker build process. Also, you're missing the .dll at the end of the project name in the ENTRYPOINT.

Try replacing yours with something similar to this one (some routes may need to be adjusted, this assumes the Dockerfile is placed at .csproj level and the project has no other dependencies):

the problem is in your view loader. when you load view in the package , you should write two colons like this:

The documentation for the run command can be found here: https://docs.docker.com/engine/reference/commandline/container_run/

Essentially it states

docker container run [OPTIONS] IMAGE [COMMAND] [ARG...]

It works with "ls" since ls is a valid unix command. However you are passing the command and the args together in the command value. Docker is failing since there is no command "ls /mnt" You need to pass this as command and arg "ls" "/mnt"

Have you tried with hos ip as your PostgreSQL host. I have just tested with asp.net core 3.1 and PostgreSQL both in windows 10 docker Linux separate container.

Its running without issue.

my connection string is

optionsBuilder.UseNpgsql("HOST=192.168.1.100;DataBase=TestIdentity;UserName=postgres;Password=*****;");

First about you Docker:

The docker EXPOSE 50 is only known for docker, dotnet knows nothing about docker. So in your DockerTest.dll you must also specify the listening port.

dont use port 50, it is too low. Anything below 1024 is seen as well-known ports or system ports and should not be used. dotnet normally listening on port 5000 - when it is not 80/443.

Second about you access to the host:

When using localhost inside the docker container, it will not reach the host but only th container itself. So you have to use the Host LAN ip i.e. 192.168.. or something...

First of all you cannot combine two Docker images by using multiple FROM lines one after another. The reason it's even possible to specify more than one is to enable multi-stage builds.

Second, if you're not using this line:
