I am starting to learn Docker.
On Docker Hub I found the Oracle Database Enterprise Edition Container which I would like to play around with.
Can I use Kitematic to controll the container? I have not seen Oracle DB in Kitematic.
Kinematic helps to seamlessly switch between Kinematic GUI or Docker CLI to run and manage your application containers.
Just install Kitematic on your system. Start any container on your system which can be your Oracle DB.
Once the container is started, you can open kitematic and see the running containers in it.

I would like to build an application as an executable that anyone could start without any requirements and without GUI.
Do you know if we can bundle a Docker image as an executable app for Mac OS or Windows (and Android/iOS) ?
Another way to phrase it, can we run docker images without docker installed ? can we bundle a docker image and docker inside an app and when executed it starts a docker container with the embedded docker ?
Docker is just a set of linux features (windows containers use similar windows features), so as long as you pack what ever you need to set everything just like docker (or any other container runtime like podman) does for you it will probably work. Just notice if using a docker image you'd need to unpack its files and do everything the docker engine and CLI are doing for you.
It depends on the application type but you could use a PWA which runs as a native desktop application on computers and smartphones and has similar functionality while using general purpose web frameworks like React, Angular or Vue.
If you want to run an executable regardless of the operating system or architechture docker's your best bet, and if being light weight and daemonless is your thing consider using podman as your application dependency and running your application
with it or its likes
I'm using Azure DevOps, and have a Linux build pipeline (ubuntu-16.04) setup that builds the code, starts containers with Docker Compose, then runs integration tests using the containers. This all works great.
Now I want to setup a Windows build pipline that does the same thing. However, with both the windows-2019 and win-1803 images, when I do docker stack up, I get this error message:
image operating system "linux" cannot be used on this platform
So, I guess Docker is installed in Windows mode, and thought to switch it to Linux containers using:
DockerCli.exe" -SwitchLinuxEngine
or
"%ProgramFiles%\Docker\Docker\DockerCli.exe" -SwitchLinuxEngine
However, the DockerCli.exe executable doesn't seem to be installed at all.
The only 2 things I can think of are:
Setup a self-hosted build agent
Somehow start the required containers somewhere else
But both of these will be a lot of work to setup, which I really don't need, neither do I want the running costs, or the job of maintaining it.
Are there any workarounds to run Linux containers on hosted Windows build agents?
Run Linux containers in an Azure DevOps Windows hosted build agent
Firstly, see the images listed which installed on Windows hosted agent: Docker images in Windows hosted agent. Docker EE on Server does not support Linux containers at all. So, it is impossible to build Linux docker image on Hosted Win-1803 agent. It can only build Windows docker image.
Until now, the only two workarounds is using self-hosted agent which based on Windows machine, or run a build which has two separate agent jobs(Pass the build artifacts back and forth between one agent job which run on Hosted Linux agent and the other is running on Hosted Windows agent) .
But since these two workarounds are all not convenient for you, there will not any other work around can achieve what you want.
In addition, there has a such suggestion feature raised on our official forum: Support for Docker with Linux Containers on Windows (LCOW) on hosted agent pool . You could vote and comment there, our Product Group team will review these suggestions regularly and consider taking it as Developer Roadmap. If this feature can be true, I think it will be very convenient to build Linux Container and without considering about which agent can only support.
I am unable to run linux containers as I run Docker in my development vm which has visual studio installed and I have not been ablt to get it working yet as it is an unsupported scenario and many of the google solutions have unfortunately not resolved it for me.
However, I was thinking that maybe I could keep Docker Desktop running on my dev vm (so that VS would be happy it was still "local") but actually have the Docker engine/daemon bit running on a remote host where linux containers actually work - is it possible to repoint Docker Desktop for Windows to a Docker engine on a remote host?
Apologies if my terminology is rubbish, I am new to Docker. Also, I have done some searching and have seen articles and messages talking about docker machine and DOCKER_HOST environment variables, but I cannot see anything yet that applies to Docker Desktop (e.g. I don't have that env variable set on my docker windows vm so maybe it doesn't use that mechanism).
Thanks in advance
I'm just starting with mongoldb (Installed today!).
I installed mongoldb on my ubuntu laptop (already acting as a mySQL server).
I want to be able to work with the mongodb database remotely from my mac.
What do I need to do?
Do I need to install mongodb on my mac as well?
I am trying to install Oracle database software in RHEL7 Docker container.
Is such configuration supported?
I do not find any useful guide to do same.
It's possible, but as RDBMS is not yet tested or certified with Docker, there are no official resources available yet. Also, it's unlikely that you'd get full support for RDBMS within a container (either Docker or generic LXC) at this stage either.
This guide should work:
