--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.

++In eMagiz's current runtime architecture, Docker technology plays a central role in deploying runtimes. eMagiz creates specific runtime images tailored for dockerized environments, streamlining deployment. This section focuses on preparing a Linux server for the installation of the eMagiz Deploy Agent, which facilitates downloading these runtime images from the eMagiz infrastructure.

++In the current 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.
++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.

++
++==== 3.2.2 Install Docker ====
++
++To install a specific version of Docker Engine, start by listing the available versions in the repository:
++
++{{code language="cmd"}}
++apt list --all-versions docker-ce
++
++docker-ce/noble 5:29.1.5-1~ubuntu.24.04~noble <arch>
++docker-ce/noble 5:29.1.4-1~ubuntu.24.04~noble <arch>

++sudo apt install docker-ce=$VERSION_STRING docker-ce-cli=$VERSION_STRING containerd.io docker-buildx-plugin docker-compose-plugin
++{{/code}}
++
++==== 3.2.3 Customization ====
++
++After installing Docker you have the option to stick with the standard configuration of Docker or you can opt to alter some specific settings. One setting that can be of particular interest is the setting that defines the IP address range your Docker installation will use to run the containers.
++
++===== 3.2.3.1 IP address range =====
--== 7. Silent demonstration video ==
++Below you can find the recommended values depending on the range which can be filled in the value <ip-address> below:
++* 10.0.0.1/8
++** advised value 10.25.0.1/16
++* 172.16.0.1/12

++{{code language="cmd"}}
++sudo nano /etc/docker/daemon.json
++#Add following lines
++{"bip": "<ip-address>"}
++{{/code}}
++{{warning}}Be aware that the customization will only take effect once you have restarted Docker.{{/warning}}
++
++==== 3.2.4 Verify succesfull installation of the Docker Engine ====
++
++{{code language="cmd"}}

++
++=== 3.3 Update Docker ===
++When you are advised to update your Docker version, you can follow the following procedure to update to a specific version of Docker Engine, start by listing the available versions in the repository:
++
++{{code language="cmd"}}
++apt list --all-versions docker-ce
++
++docker-ce/noble 5:29.1.5-1~ubuntu.24.04~noble <arch>
++docker-ce/noble 5:29.1.4-1~ubuntu.24.04~noble <arch>
++...{{/code}}
++
++Select the desired version and install.
++
++{{code language="cmd"}}
++VERSION_STRING=5:29.1.5-1~ubuntu.24.04~noble
++sudo apt install docker-ce=$VERSION_STRING docker-ce-cli=$VERSION_STRING containerd.io docker-buildx-plugin docker-compose-plugin
++{{/code}}
++
++{{warning}}It may happen that, due to the update, your containers are no longer starting up. To resolve this, please restart the containers, which can be done via a deployment plan or the deploy architecture.{{/warning}}
++
++===3.4 Uninstall Docker===
++To uninstall Docker from your machine, execute the following command.
++
++{{code language="cmd"}}
++sudo apt purge docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin docker-ce-rootless-extras
++{{/code}}
++
++{{warning}}Images, containers, volumes, or custom configuration files on your host aren't automatically removed. To delete all images, containers, and volumes:
++
++{{code language="cmd"}}
++sudo rm -rf /var/lib/docker
++sudo rm -rf /var/lib/containerd
++Remove source list and keyrings
++{{/code}}
++
++{{code language="cmd"}}
++ sudo rm /etc/apt/sources.list.d/docker.sources
++ sudo rm /etc/apt/keyrings/docker.asc
++{{/code}}
