Can i create a docker container with HP UX and IBM AIX, if so please let me know how to do it?
I tried by creating container from HP UX tar, it got created and i got conatiner id but unable to login in to the container.
Let me know where i am doing wrong.
If you look in the FAQ https://docs.docker.com/faq/ you will see as supported
Ubuntu 12.04, 13.04 et al
Fedora 19/20+
RHEL 6.5+
Centos 6+
Gentoo
ArchLinux
openSUSE 12.3+
CRUX 3.0+
This github issue is closed at the moment https://github.com/docker/docker/issues/3546 but that could change. What you try to do is not supposed to work at the moment (which says nothing about the technical possibility)
The IBM developerWorks site has a guide on how to do this, I'm currently doing similar work on Z at the moment.

No. It is impossible to build AIX and HP-UX docker containers because the AIX and HP-UX are totally different operation systems with differently build closed SystemV kernels running only on RISC based CPU's compared to the wide spread Linux distributions running on almost everything.
If you have applications that only runs on AIX or HP-UX but you want them in a container, AIX has the option of using Workload Partitions, which is almost comparable with containerization.

I want to ask about cross platform compatibilty of Docker ,means if an application is designed to run in a docker container on windows,then can it run on linux or vice -versa?
Docker was create to run on Linux, so the short answer is yes.
The Windows version isn’t stable or recommend (Docker for windows). At least not by now.
“But, Fischer, I use Docker on Windows!” Yes, with WSL (windows subsystem for linux - Some kind of VM), which you can configure to set a memory limit, using the .wsconfig file, and if you look at your Windows Menu you may found a Ubuntu icon, that connects you to the bash.
Docker is largely used for people that develop software, and today many languanges and frameworks use linux, even Microsoft with .Net runs on Linux.
Docker was created to resolve one simple issue: "But it works on my machine." So, it means that a container should run on every platform. At least "it works on my computer" lol
I think the question is regarding a Windows application. If that's the case, a Windows application cannot simply run on Linux containers. For example, .Net Framework doesn't run on Linux. If an application was targeted for Windows, it needs to run on Windows and in that case only a Windows container can run the application.
Docker Desktop can run both: Windows containers and Linux containers, just not at the same time. You have to switch the context so Docker Desktop can target either WSL (for Linux) or HCS (for Windows).
it is possible to install docker desktop on virtual machine (vmware) windows 10 on a VMWARE ESXI ?
i am trying to install desktop docker on my vmware virtual machine with windows 10.
I installed the wsl2 support but at the end of the installation docker crashes with the following error:
Docker desktop 4.0.1
Installation failed
Component CommunityIstaller.ServiceAction failed to start services: The service did not respond to the start or control request in a timely fashion
I have done several tests but I cannot avoid this crash in any way.
The Operating System is a build that meets the minimum requirements to install Docker.
However, I noticed that Hyper-V is not enabled in the windows features. can this be a problem?
I think maybe it's a grafted virtualization problem because I install docker inside a VM. it's possible?
How can I solve? (or do you think that i will fix this problem with linux virtual machines?)
Does your host machine have all the advanced flags for 'efficient' nested virtualization? I wouldnt really recommend a third layer install of docker (as the final container is then virtual , on paravirtual (wsl2) on virtual (HyperV), on virtual (Esxi). I heavily assume the performance will be terrible.
And yes: You need Hyper-V, it's a requirement still. I assume, as you say its not available on the features, youre running a windows 10 home? Then sorry, you need at least Windows 10 Pro for Hyper-V support.
But as youre running a ESXI host, go the better performing way: Install any Linux distro of your choise, install docker there - if you wanna use it for Visual Studio etc. , you can still remotely debug etc. - and its performing better than on an a even deeper nested virtualized windows-wsl2. And btw: if its because of GUI, simply install the free Visual Studio Code, it offers Docker Tools which offer you many configiruation and monitoring options in a GUI , without enforcing you to do such a super deep nesting.
Yes, it's definitely possible. I'd probably check the hardware assisted virtualization (if available) is enabled. If so, you might want to make sure you've satisfied the rest of the requirements for the WSL2 backend deployment. If you're still having issues, try an older version and try upgrading from there.
I am very new to docker. I have installed docker desktop on my mac. When i execute docker version it is showing OS/Arch:linux/amd64 under server docker engine. I am assuming this means that docker installed linux kernel on top of my mac OS using hypervisor to manage linux based containers. if this linux kernel got updated, will it going break the functionalities of existing images?
Why am I asking this question?
Recently after updating my mac OS to 10.15.2, things started breaking because of openssl and ruby-2.3.x compatibility issues. And I was told, we could solve these type of issues using docker since it is independent of host OS?
But docker itself has own linux kernel, Will i be going to face this issue if linux kernel got updated?
Thanks in advance
You got those errors because you were depending software libraries available on the machine. They are not related to kernel. Any such software dependencies should be bundled with the docker image. Linux kernel upgrades never break user space.
I am using windows 10 Home. But with this edition I am unable to use docker or oracle vm virtualbox. So can I use Podman in place of docker? If yes then what is it's command?
At this date, the answer is no, you cannot use podman to run containers on Windows 10 Home.
Podman is very much a Linux program at this point. This big issue that I see for podman is the file system layering code. Given that podman is developed by Red Hat, it will probably require a partnership with Microsoft to make this happen. In that regard, Microsoft is developing their own tools for containers.
Now Podman is supported on Windows.

I would like to use the Spark-graphX packages available to Neo4j through Mazerunner, however I am an analyst and not a software person. I am running Windows 7 on my laptop and Neo4j 2.3.0, and would like a step-by-step guide explaining how I can set-up Mazerunner for both Community & Enterprise. There's a lot of mention of dockers and containers, and I have no idea what these are, or how to set them up. Simple instructions would be of sooo much help! :)
Docker is primarily Operating System Level Visualization technology designed to run on Unix based systems (Linux,Mac,FreeBSD). Luckily Docker provides a Windows version that sort of does the same thing on Unix.
What happens is, after you have installed Docker, it allows you to run what they call containers which are basically virtual machines on top of your host (Windows 7 Running Docker). This allows you to run services like Neo4j in an isolated environment. Docker also allows you to download and install pre-configured, pre-compiled images of operating systems that usually provide some sort of service or have some software pre-installed.
In your case, I believe all you have to do is:
First install Docker
Use "Docker Compose" to download and install the images.
Continue Reading the Tutorial as you have now installed the required docker images
Note: Some of the operations, like the one in Step 2 will require command-line access and Also the creation of a "docker-compose.yml" so, be sure to visit all the links I have provided. Spend a little time going through them and you should be alright.
