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 ** Preferably the entry should be *.emagiz.com{{/info}}
26
27 {{warning}}
28 * In case of a very strict firewall configuration, additional configuration is needed.
29 ** controltower.emagiz.com:443
30 ** controlbus.emagiz.com:443
31 ** controlplane.emagiz.com:443
32 ** controlplane.emagiz.com:8000
33
34 * When using a lower or equal version to 125, additional configuration is needed.
35 ** 35.158.46.28:443
36 ** 3.74.190.88:443
37 ** 35.158.46.28:8443
38 ** 3.74.190.88:8443
39 ** 35.158.46.28:8444
40 ** 3.74.190.88:8444 {{/warning}}

42 ===3.2 Installation Linux===
43 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.
44
45 ==== 3.2.1 Set up Docker's apt repository ====
46
47 {{code language="cmd"}}
48 # Add Docker's official GPG key:
49 sudo apt-get update
50 sudo apt-get install ca-certificates curl
51 sudo install -m 0755 -d /etc/apt/keyrings
52 sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
53 sudo chmod a+r /etc/apt/keyrings/docker.asc
54
55 # Add the repository to Apt sources:
56 echo \
57 "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
58 $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
59 sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
60 sudo apt-get update
61 {{/code}}
62
63 ==== 3.2.2 Install Docker ====
64
65 {{code language="cmd"}}
66 sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
67 {{/code}}
68
69 ==== 3.2.3 Verify succesfull installation of the Docker Engine ====
70
71 {{code language="cmd"}}
72 sudo docker run hello-world
73 {{/code}}
74
75 {{info}}
76 Requires ~335 Mb space to install
77 {{/info}}
78
79 ==== 3.2.4 Install eMagiz Deploy Agent ====
80
81 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"]]
82
83 == 4. Key takeaways ==
84
85 * 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
86 * eMagiz has a specific agent that manages the download of that image to the on-premises server
87 * 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.
88
89 == 5. Suggested Additional Readings ==
