2 In this microlearning, we will focus on how an on-premises server can be prepared for a eMagiz Deploy agent installation.
3
4 Should you have any questions, please contact [[academy@emagiz.com>>mailto:academy@emagiz.com]].
5
6 == 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 Linux variant is described in terms of how to prepare the server to allow the [[eMagiz Deploy Agent>>doc:Main.eMagiz Academy.Microlearnings.Intermediate Level.eMagiz Runtime Management.intermediate-runtime-management-deploy-agent.WebHome||target="blank"]] to be installed. That agent allows to download images from the eMagiz infrastructure.
15
16 == 3. On-premises deployments ==
17
18 ===3.1 General requirements===
19 These are the general requirements to allow the installation of the eMagiz Docker agent:
20
21 {{info}}
22 * Standard configuration to ensure that communication between your server and eMagiz to ensure communication.
23 ** registry.emagiz.com:443
24 ** controlplane.emagiz.com:8000
25 ** controltower.kpn-dsh.com:443
26 ** Preferably the entry should be *.emagiz.com
27 ** Preferably the entry should be *.kpn-dsh.com{{/info}}
28
29 {{warning}}
30 * In case of a very strict firewall configuration, additional configuration is needed to communicate to the eMagiz infrastructure.
31 ** controltower.emagiz.com:443
32 ** controltower.kpn-dsh.com:443
33 ** controlbus.emagiz.com:443
34 ** controlplane.emagiz.com:443
35
36 * When using cloudslot number **equal to or below** 125, the following configuration is needed to communicate to your JMS.
37 ** 35.158.46.28:443
38 ** 3.74.190.88:443
39 ** 35.158.46.28:8443
40 ** 3.74.190.88:8443
41 ** 35.158.46.28:8444
42 ** 3.74.190.88:8444
43
44 * When using a cloudslot number **above** 125, the following configuration is needed to communicate to your JMS.
45 ** 3.74.209.20:443
46 ** 3.76.127.155:443
47 ** 3.74.209.20:8443
48 ** 3.76.127.155:8443
49 ** 3.74.209.20:8444
50 ** 3.76.127.155:8444{{/warning}}

52 ===3.2 Installation Linux===
53 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.
54
55 ==== 3.2.1 Set up Docker's apt repository ====
56
57 {{code language="cmd"}}
58 # Add Docker's official GPG key:
59 sudo apt-get update
60 sudo apt-get install ca-certificates curl
61 sudo install -m 0755 -d /etc/apt/keyrings
62 sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
63 sudo chmod a+r /etc/apt/keyrings/docker.asc
64
65 # Add the repository to Apt sources:
66 echo \
67 "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
68 $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
69 sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
70 sudo apt-get update
71 {{/code}}
72
73 ==== 3.2.2 Install Docker ====
74
75 {{code language="cmd"}}
76 sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
77 {{/code}}
78
79 To install or update docker on your machine, execute the following commands in powershell with administrative rights:
80
81 {{code language="cmd"}}
82 Invoke-WebRequest -UseBasicParsing "https://raw.githubusercontent.com/microsoft/Windows-Containers/Main/helpful_tools/Install-DockerCE/install-docker-ce.ps1" -o install-docker-ce.ps1
83 .\install-docker-ce.ps1
84 {{/code}}
85
86 Example usage:
87
88 {{code language="cmd"}}
89 .\install-update-docker-ce.ps1 -DockerVersion DESIRED_VERSION
90 {{/code}}
91
92 To install the latest version of docker, you can use {{code language="cmd"}}e .\install-update-docker-ce.ps1{{/code}} without specifying the version flag.
93
94 {{info}}lIt is advised to use Docker version 24.0.7 as this is the version being used in the latest eMagiz cloud template. We advise to align the on-premise Docker version and update it according to the release notes of the Cloud templates.
95 {{/info}}
96
97 {{warning}}Note: This process is service affecting, your running containers will be stopped and will need to be started again.{{/warning}}
98
99 ==== 3.2.3 Verify succesfull installation of the Docker Engine ====
100
101 {{code language="cmd"}}
102 sudo docker run hello-world
103 {{/code}}
104
105 {{info}}
106 Requires ~335 Mb space to install
107 {{/info}}
108
109 ==== 3.2.4 Install eMagiz Deploy Agent ====
110
111 Install the eMagiz Deploy agent as can be found in this [[microlearning>>doc:Main.eMagiz Academy.Microlearnings.Intermediate Level.eMagiz Runtime Management.intermediate-runtime-management-deploy-agent.WebHome||target="blank"]]
112
113 == 4. Key takeaways ==
114
115 * 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
116 * eMagiz has a specific agent that manages the download of that image to the on-premises server
117 * 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.
118
119 == 5. Suggested Additional Readings ==
120
121 * [[Docker official installation guide>>https://docs.docker.com/engine/install/ubuntu/||target="blank"]]
122 * Docker command line cheatsheet: [[image:Main.Images.Microlearning.WebHome@docker-cheatsheet.png]]
