Hi,
I'm developing an application using abp.io with Angular front-end. I'm trying to deploy and run the api into Docker container. I used Visual studio Docker support which creates a Dockerfile under project *.HttpApi.Host. The Docker image is created and a container runs successfully. But when I try to access the api from Docker using http://localhost:<Docker port> from browser, it is not accessible. However, the api is accessible when it runs from local machine using Visual Studio like http://localhost:44306.
Question -
- Do we have some instructions/guidelines/scripts to deploy and run abp.io asp.net core api into Docker container? To extend it further, I want to deploy and run it from AWS ECS.
- How do we map port of local machine which is specified in appsettings.json to the port of docker container?
Let me know if you require additional information. Any help, suggestions would be welcome.
Thanks, Repunjay

Hello,
I used Visual studio Docker support which creates a Dockerfile under project *.HttpApi.Host. The Docker image is created and a container runs successfully. But when I try to access the api from Docker using http://localhost:-Docker port- from browser, it is not accessible. Visual Studio runs the containers with additional parameters (like located inside docker-compose.vs.debug.g.yml). Your http server (kestrel) is alive as long as you are debugging it. That's why you can't access them when you are not running through Visual Studio. So, you manually need to build the docker images for production.
Question -
Do we have some instructions/guidelines/scripts to deploy and run abp.io asp.net core api into Docker container? To extend it further, I want to deploy and run it from AWS ECS. We are planning to add guideline about how to run abp on containers for both development and production. However I can't hint a date about it unfortunatelly.
How do we map port of local machine which is specified in appsettings.json to the port of docker container? You can pass the port as environment variable from top to bottom (env-> docker -> appsettings)
Hope it helps.

Hi,
I'm facing another issue when try to deploy and run aspnet-core project into Docker Container (Windows). The image is successfully created but the docker container doesnt run and exits. When I checked the logs, I found below issue - Could you please advise on resolution steps for this issue? Kindly note, that I have a commercial license code for abp.io and it works properly when I run code from local machine.
