| 楼主： | How to run app FMX (GUI) in a Ubuntu on Docker environment? by Emailx45 hello boys and girls, here my tutorial to use Docker and RAD Studio to deploy your (GUI or not) apps in Ubuntu Linux! Now you can deploy your apps with all infra-structure to local or remote server! the article is a little big, then, I can not reproduce here because the forum "deny" many text in my post! to go WeDelhi forum and see if you want, ok? if your not registered, just do it -- it's free for all! How to run app FMX (GUI) in a Ubuntu on Docker environment? by Emailx45 with screenshots for show how? How to run app FMX (GUI) in a Ubuntu on Docker environment? by Emailx45 RAD Studio + Docker + Ubuntu + XvcSrv togheter + WSL https://wedelphi.com/t/422402/#post-3471139 NOTE: Docker share images files with WSL if it is installed in your computer

| 4楼： | remember: DOCKER is created based on Linux subsystems of virtualization (basically using KVM and others) for that it was create (initially) by Linux systems... like Ubuntu, macOSes etc... later, to MSWindows! Said this, if you have a macOS or Linux hosts, you have more compatibilities between "hosts" and "clients" (+/- you understood?) then, why to use Docker ? as I said in my post in WeDelphi, it's simple! -- you can create a "image customized of your O.S. (Windows, Linux, macOS if Apple let) and "upload" to a hub (like Docker-Hub) public or privated! after this, your "image" can be download for any one to use it! at end, you'll have your infra-structure and libs (softwares etc...) all ready for use at any time! No more format C: ... install or setting devices and install O.S. and install applications... NO! NO! NO! you can upload your infra-structure (image custom) for a "Local computer" or "Remote computer (clouds)"... easy easy... just do the reference in your "Dockerfile" ... FROM ....(your image custom) ... the rest is with Docker! NOTE: Docker dont re-download files already downloaded before, just new files redefined on "Dockerfile" on re-build image! if your needs changes your image or container, dont worry. just rebuild it your image re-defining your "Dockerfile"... each day, a new computer ready for use! now if you have many distincts scenary with same base O.S, for example: 1 image=O.S. and infinite containers can be created! the Docker just share and use the resources indicated in your "Docker file" for each container... then, you dont need a "big hardware" for "little tasks". so... it's really good for all developers currently! regular VMs it's good, but softwares like "DO"cker it's better! no doubt! take a have fun boys and girls! ---------------------------------------------- The higher the degree, the greater the respect given to the humblest!RAD 11.3 |

| 10楼： | First, a Docker is a "virtualizer" based on Linux virtualizers, like KVM! NOTE: --- Hardware: any "phisical" element in the process --- Virtual Machine/Virtualizer: any software to "simulate a hardware environment" --- User: anyone, like: John, the developer, the tester, etc... --- Client: any application client, ex.: VirtualBox is a client in relationship to the Operating System. --- Operating System: any software to "give life" for your hardware --- Application: any software, understanding, to end-user In virtualizer likes VirtualBox and similars, we have basically the follow layers: 1) Hardware ---- phisical components (like: Servers, DataCentes, PCs, mobiles, etc...); 2) Hipervisor ---- (virtualizer like: VirtualBox, VMWare, ProxyMox, KVM, Hyper-V, etc..), works like a "Operating System for your hardware"; ---- your "mission" it's create another "Operating System" (installed directly on Hardware), allowing create another "Operating System" layer... ex. VirtualBox VMs. 3) Virtual Machine ---- create a "new" hardware (virtually) to receive an "Operating System" to run some "Application" to end-user ---- Ex.: VirtualBox, VMWare, etc... 4) Operating System ---- the final "Operating System" to run the "Application" of user. ---- Ex. MS Windows 10, Ubuntu, Big Sur, etc... 5) Application ---- any "Application" of the user ---- Ex.: DataSnap Server, My Account System, etc... NOTE: -- in these concept, we allocating the "hardware whole" just to run an "Application"! ---- Ex.: create a "VM" with MSwindows 10 to run my DataSnap Server in a PC i9 with 512GB RAM, GPU nVidia 12GB, 16TB disks, 100 Ethernet interfaces, 16 Mouses, 14 keyboards, etc... (ha ha ha...) :love: ---- Is it really necessary? What we can note here? there are much hardware resources to a specific task from the final-software! if the final-software needs any changes on infra-structure is necessary another hardware and setting! this "changes" can "break" anothers final-software installed static environment, like a "read-only environment"! With "Docker" (or similars in each platform), we have this layers: 1) Hardware ---- phisical components 2) Operating System ---- any O.S. supported! 3) Container Engine (==> Docker, or any other similar!) ---- each "container", in fact, just share the same Kernel for O.S. host ("from platform-image of platform") and isolate the specific characteristics for your use!, in a "name-spaces" concept! NOTE: -- in these concept, we allocating just hardware-resources minimum and necessary to run the final-applications! ---- Ex.: my application needs just 400MB RAM and 20MB disk, then, why a VM with 2GB RAM, 30GB disk? -- the "containers" is a "packages isolatating", then, we can have many "containers" of a same "platform-image"! each one is distinct each other and independent! ---- all libs/files necessary to run your application will be packed in a "container" ---- easy to install and run in any environment local or remote! take and run! ---------------------------------------------- The higher the degree, the greater the respect given to the humblest!RAD 11.3 |

| 11楼： | then, if you "HOST" is ARM, and your "Operating System" that you go to use accept "ARM" archtectur, then, Docker just use it! Docker dont create a new "virtual PC", it just use the phisical-resources to create a "specific container where the resource is used"... you understood? like VirtualBox create a VM with all resources non-mutable (all phisical components are simulated by software and dont changes like a real-pc), and DONT create new phisical-components-virtualized. then, Docker is just a optimizer when using resources in your host-pc. or be, it dont use nothing that you dont need! But the resources should exists in your host, else, how to use some that not exists? you understood? ---------------------------------------------- The higher the degree, the greater the respect given to the humblest!RAD 11.3 |

| 12楼： | Multi-arch support on Docker Desktop Docker Desktop provides binfmt_misc multi-architecture support, which means you can run containers for different Linux architectures such as arm, mips, ppc64le, and even s390x. This does not require any special configuration in the container itself as it uses qemu-static from the Docker for Mac VM. Because of this, you can run an ARM container, like the arm32v7 or ppc64le variants of the busybox image.  https://docs.docker.com/desktop/multi-arch/---------------------------------------------- The higher the degree, the greater the respect given to the humblest!RAD 11.3 |

| 14楼： | First, DOCKER DONT INSTALL ANY O.S.!!! It just "is a method of you choice any resource from your host-pc/Operating System you need in your final-"container"... let's try understood this: 1) I need a MSWindows 64bit just for run my app-server with some resources basic... Ok, then you needs a O.S MSWin 64bits, but you host-Pc dont run MSwin64bits... ops!!! how to do then? it's not possible... and Docker dont help here! VirtualBox help me then? maybe.... if it can "emulate a MSWin64bits"! But, your CPU it's 64bits? IF (yes) THEN continue ELSE exit! now, let's go to Docker! 1) I have a phisical pc with 64bits CPU, ARM! Oh! then I can run any O.S. 64bits to ARM here in my pc! Oh! in this scenary, you can first: 1) install a O.S. to ARM archtecture 64bits 2) emulate anothers scenary ARM arch 64bits 3) install any others O.S. ARM arch 64bits now, if need emulate many scenarys with distincts distribution... then you can use Docker for this! At end, Docker is just a "package manager" for your "file layers", or be, if a "container" needs just lib XORG, and other need just lib X11, then, you can create two "containers" (one for each other) the image-base (shared) will contain 2 libs, but when run, just 1 for each container.... this is done by Docker.... you understood now? ---1 image-base-O.S. with 2 libs ---2 container (1 with XORG, 1 X11) = Docker at end, your apps dont need all resources in your host-PC for run. then, you can many others scenary in your same pc! optmized! ---------------------------------------------- The higher the degree, the greater the respect given to the humblest!RAD 11.3 |

| 17楼： | first, if your PC is ok for receive many O.S. (consuming resources in same time), I think that "YES". You can found in Docker-hub or Microsoft "Windows-images" (many) starting with "Windows core"... until others more specific customizations! Official or not! then, if your PC it's ok to run it, you can install your RAD Studio IDE in it. in Docker-Hub you can found Microsoft Official distribution: https://hub.docker.com/_/microsoft-windows windows/nanoserver: Nano Server base OS container image windows/servercore: Windows Server Core base OS container image windows/server: Server base OS container image windows/insider: Insider version of this base OS image. NOTE: Read the "TAG" description for know more about each image that will be downloaded ex.: docker pull mcr.microsoft.com/windows/nanoserver:ltsc2022 This is a base image for Windows Server containers. This image carries the Nano Server base OS image. For more information about servicing lifecycles, visit Base Image Servicing Lifecycles. https://docs.microsoft.com/en-us/virtualization/windowscontainers/deploy-containers/base-image-lifecycle ---------- of course, you needs to know if this "images" it's ok for install RAD Studio or needs add new libs ( like .NET Frameworks, DirectX (for FMX), etc...) at end, you can try install your RAD. you understood? NOTE: --- in my opinion, this only necessary if you needs run 2 or more instance of "same RAD", because the RAD can co-exists with others editions, like, RAD 10.1 and 10.2 for example in the same pc! --- RAD Studio allow you run another instance just indicating another "profile / user" in your command-line! then you can use distincts components / pallete for example! BDS.EXE -R <<your-registry-key>> Alternate registry key. Allows you to specify an alternate base registry key so you can run two copies of the IDE using different configurations. This allows component developers to debug a component at design time by using the IDE as the hosting application, without the debugging IDE interfering by trying to load the component package being developed. ---------------------------------------------- The higher the degree, the greater the respect given to the humblest!RAD 11.3 |
