On-premise Install Guide

{{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.

== 1. Prerequisites ==

7

8

* Advanced knowledge of the eMagiz platform

9

* Good understanding of eMagiz runtimes in general

10

11

== 2. Key concepts ==

12

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 environments.

13

14

In the below section the specific operating systems and versions are discussed in a sense that the prerequisite installations are described. Once the right installation is done, refer to section 3.7 for the installation of the eMagiz agent that manages the interaction with the eMagiz platform. That agent will download the created docker images that will be deployed in the Docker environment.

20

These are the general requirements to allow the installation of the eMagiz Docker agent:

21

* Ensure access to the following URLs is enabled

22

** registry.emagiz.com:8443

23

** controlplane.emagiz.com:8000

24

* Whenever Linux is selected as operating system, the latest version of Ubuntu will work. Other Linux distributions will also work such as Debian or Red Hat.

30

* Install latest version of the Docker engine - see for instance this link below. For other Linux distributions similar install guides are available on this link.

53

The steps below will install a linux subsystem under Windows. In that Linux system, Docker and Java will be installed. Please note that the Windows server needs to be able to run Virtualized (either via BIOS setting or via Nested Virtualization).

54

55

**Step 1: Install linux distribution**

56

57

58

wsl --install -d Ubuntu

59

sudo apt-get update

60

sudo apt install --no-install-recommends apt-transport-https ca-certificates curl gnupg2

. /etc/os-release

**Step 2: Install Docker **

66

67

68

curl -fsSL https://download.docker.com/linux/${ID}/gpg | sudo tee /etc/apt/trusted.gpg.d/docker.asc

69

echo "deb [arch=amd64] https://download.docker.com/linux/${ID} ${VERSION_CODENAME} stable" | sudo tee /etc/apt/sources.list.d/docker.list

70

sudo apt update

71

sudo apt install docker-ce docker-ce-cli containerd.io

Requires ~335 Mb space to install

76

77

78

**Step 3: Install Java **

79

80

81

wget -O - https://packages.adoptium.net/artifactory/api/gpg/key/public | sudo apt-key add -

82

echo "deb https://packages.adoptium.net/artifactory/deb $(awk -F= '/^VERSION_CODENAME/{print$2}' /etc/os-release) main" | sudo tee /etc/apt/sources.list.d/adoptium.list

83

sudo apt update # update if you haven't already

84

sudo apt install temurin-8-jdk

Requires ~335 Mb space to install

89

90

91

**Step 4: Ensure Docker is autostarted with WSL **

nano .bashrc

#Add following lines to bashrc

97

DOCKER_DISTRO="Ubuntu"

98

DOCKER_LOG_DIR=$HOME/docker_logs

99

mkdir -pm o=,ug=rwx "$DOCKER_LOG_DIR"

100

/mnt/c/Windows/System32/wsl.exe -d $DOCKER_DISTRO sh -c "nohup sudo -b dockerd < /dev/null > $DOCKER_LOG_DIR/dockerd.log 2>&1"

101

102

103

**Step 5: Add user to Docker group **

sudo visudo

#Add following lines

# Don't ask for password

111

%docker ALL=(ALL) NOPASSWD: /usr/bin/dockerd

112

113

114

**Step 6: Update wsl config file **

115

In this step we need to add or update the WSL config file that manages the resources of the Linux subsystem. Important resources to manage are the assigned memory and number of processors. For memory we recommend to review the mempory settings for the runtime that need to run on this server and add 762 MB to the total value of the heap and non-heap of these runtimes. For processor we recommend to set the value to 2 - depending on the amount of processors available on that machine

116

117

First, locate the config file or add it to the location %USERPROFILE%. The name should be .wslconfig (no extension)

#Add following lines

# Settings apply across all Linux distros running on WSL 2

124

[wsl2]

125

# Limits VM memory to use no more than 4 GB, this can be set as whole numbers using GB or MB

126

memory=16GB

127

# Sets the VM to use two virtual processors

processors=2

**Step 7: Auto start the linux subsystem when server restarts **

=== 3.7 eMagiz Docker agent installation ===

181

182

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 under Deploy Architecture. At the runtime connector, there is a right click option called Deploy Agent. That presents either the command or the location where that agent is installed.

After installing the agent, you can use the Docker cheat sheet below to see if the docker containers are running and/or images are available.

== 5. Key takeaways ==

195

196

* 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

197

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

198

* 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.
