On-premises deployment new runtime architecture

{{container}}{{container layoutStyle="columns"}}(((

In this microlearning, we will focus on how the installation requirements for on-premises deployments of eMagiz runtimes that are part of the new runtime architecture. The new runtime architecture uses a containerized approach to deploy runtimes.

* Advanced knowledge of the eMagiz platform

12

* Good understanding of eMagiz runtimes in general

== 2. Key concepts ==

15

In the new runtime architecture of eMagiz, Docker technology is used to deploy runtimes. eMagiz creates specific runtime images that contain the eMagiz runtime, and can be deployed in dockerized envirionments

===3.1 Installation requirements Windows Server 2019 version 1806===

20

21

Below the installation step for this version of Windows

22

23

* Enable Hyper-V in Windows Server

24

** Go to Server Manager, Manage (top right), enable roles and features, select the desired roles and server selections. In the Features section, enable Hyper-V.

25

** Restart windows

26

* Install Docker Desktop on the Windows Server

27

** Please refer to this link: https://www.docker.com/products/docker-desktop/

28

** Restart windows

29

* Update Docker desktop configuration

30

** Go to settings, and enable ‘Expose daemon on tcp://localhost:2375’ without TLS

31

** Restart Docker

32

* Open Powershell as Administrator

33

** Execute "C:\Program Files\Docker\Docker\DockerCli.exe" -SwitchLinuxEngine

34

** Execute Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

35

** Execute curl.exe -L -o ubuntu-2004.appx https://aka.ms/wslubuntu2004

36

** Execute Add-AppxPackage .\ubuntu-2004.appx

37

*** If errors occur, please consult https://learn.microsoft.com/en-us/windows/wsl/install-on-server. Rename the file to a zip, expand it, and add it to the path variable.

38

* Ubuntu should now be a runnable program (press windows key, type ubuntu)

39

* Open the ubuntu terminal, and finish the installation.

40

** After installation, execute: export DOCKER_HOST=tcp://localhost:2375

=== 3.2 Installation agent ===

43

44

eMagiz needs to install a specific agent in the Docker instance that allows to download runtime images that needs to be installed on the Docker instance. The specific command to run inside the Docker instance is specific for the machine that is configured inside eMagiz Design & Deploy Architectures. It can be found inside the eMagiz iPaaS portal or is available upon request. Once that agent is installed, the image that is generated for every eMagiz release can be downloaded and installed in the Docker instance.

== 5. Key takeaways ==

57

58

* eMagiz uses runtime images to deploy emagiz runtime on dockerized environments. The runtime image holds all the information and components required to run the runtime

59

* eMagiz has a specific agent that manages the download of that image to the on-premises server

60

* The firewall of the on-premises environment should allow outgoing traffic without any restriction. In case that is not desirable, eMagiz can provide the addresses and ports needed to setup the right firewall rules.
