I have a pod in which i have image ubuntu desktop i connect to this image via xrdp what i want to do is to add eclipse image to this pod in other words when i connect to this ubuntu desktop i can find eclipse.
I am going to create platform based on kubernetes with image catalog.
For example a profesor of java want only ubuntu desktop and eclipse. He gonna choose from catalog ubuntu and eclipse all backend i will do it myself.
So when a student connect he will find eclipse on ubuntu desktop.
You have to create an image from a dockerfile recipe that includes a command for installing the eclipse package.
Then you can use your own image for the deployment into the cluster (instead of the ubuntu image you are using today).
Please read up how to create a docker container and dockerfile documentation.
You can also take a look at an example dockerfile.

I have Windows Docker Desktop, my os is Windows 10 enterprise , version 20h2
Docker for windows working... i have a small mvc asp.net3.1 application.
I create my docker image and i am able to run the container locally.
Everything is working from my local.
Now i uploaded the image to AWS ECR, create my taskDef and service.
Unfortunatelly the task does not start with the error :
failed to create new container runtime task: failed to create shim: hcs::CreateComputeSystem 95cade147ae4418ab3d68ea1a2c70800-2341308736: The container operating system does not match the host operat
I have seen some compatibility list from microsoft on the OS https://learn.microsoft.com/en-us/virtualization/windowscontainers/deploy-containers/version-compatibility?tabs=windows-server-2022%2Cwindows-11-21H2
I check i have hyperv and all..
Does anyone know how i can make the image compatible? This seems to be a known issues, but i am kind of blocked here.
Thanks
The error indicates you have a different image version versus the host version. What is the base image on your dockerfile? And do you know what is the host version on your AWS environment? For reference, here's the documentation on host compatibility: https://learn.microsoft.com/en-us/virtualization/windowscontainers/deploy-containers/version-compatibility?tabs=windows-server-2022%2Cwindows-11-21H2
hey I am new to docker and I want to deploy my tomcat application on cloud run , so I need to choose an image which is slim and my second question is do I need to install Java or jdk with it if I choose
tomcat:9-slim
You can explore the container content. For instance, go to that page and you can see that openjdk-11 is installed. No need to install another version (expect if you need a more recent version.
I am using VS2019 with docker support (and windows docker running). When creating a console app there is no checkbox for docker support like there is for a dotnetcore web app. This means i cannot publish a container to ACR from VS2019.
I can create a console app and then add docker support and i can build image but embarrassing enough i cannot locate the image that's built or figure how to get it into ACR. running docker ps -a shows nothing in the container list.
So: is there support for pushing containers to ACR from VS2019 console apps?
If not then exactly how do i build a docker image of a console app and get it to ACR - am i left with CLI only?
thanks

I managed to solve this.
The issue was that the underlying version of windows 10 i was on would not allow me to create a docker image using a more modern supported version of windows nano server. Once i updated windows and double checked the base image that create image was using it would all work. Take the resulting docker image and use the azure cli to push to ACR and then i can run the container from ACI...
Bit tortuous compared to creating a web app but it worked...
Is there anyway to build an image with Dockerfile while using Kitematic?
From the top of the docs for Kitematic
Legacy desktop solution. Kitematic is a legacy solution, bundled with Docker Toolbox. We recommend updating to Docker for Mac or Docker for Windows if your system meets the requirements for one of those applications.
If possible, you should avoid using the tool.
If you have to use Kitematic, the feature you are asking about is tracked by this GitHub issue: Import Dockerfile - (Docker build). At the time of writing the feature is not implemented.
I want to run Cloudera using a Docker image (specifically, the cloudera/quickstart image).
However, on Docker Hub I can only find beta versions:
https://hub.docker.com/r/cloudera/quickstart/tags/
What's the correct way of getting a more up-to-date image?
Should I just download a beta image and then install parcels? Would I do that using Docker Compose? If so, can I find instructions for that online?
Or is there a completely different way to solve this?
To run Cloudera Quickstart within Docker, follow the instructions on that page:
https://www.cloudera.com/documentation/enterprise/latest/topics/quickstart_docker_container.html
Forget about your concerns regarding the "beta" tag. These tags are there, because the Docker image of Cloudera Quickstart is in beta mode. However, the CDH version in there is not.
You will find this out on your own, once you run the container and check the CDH version inside.
