Install Docker for Linux

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

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.

== 1. Prerequisites ==

7

* Advanced knowledge of the eMagiz platform

9

* Good understanding of eMagiz runtimes in general

10

11

== 2. Key concepts ==

12

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.

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.

16

== 3. On-premises deployments ==

18

===3.1 General requirements===

19

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

20

21

{{info}}It is advised to use Docker version 29.1.3 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>>doc:Main.Release Information.Cloud Templates.WebHome||target="blank"]].

* Standard configuration to ensure that communication between your server and eMagiz to ensure communication.

26

** registry.emagiz.com:443

27

** controlplane.emagiz.com:443

28

** controlplane-agent.emagiz.com:443

29

** controltower.emagiz.com:443

31

** controlbus.emagiz.com:443

32

** {yourcloudslotid}.emagizcloud.com:8443

33

34

* Preferably we suggest to implement the following entries on DNS level.

35

** *.emagizcloud.com

36

** *.emagiz.com

37

** *.kpn-dsh.com{{/info}}

===3.2 Installation Linux===

59

60

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.

61

62

==== 3.2.1 Uninstall old versions ====

63

{{info}}Before you can install Docker Engine, you need to uninstall any conflicting packages.

64

65

Your Linux distribution may provide unofficial Docker packages, which may conflict with the official packages provided by Docker. You must uninstall these packages before you install the official version of Docker Engine.{{/info}}

66

67

68

sudo apt remove $(dpkg --get-selections docker.io docker-compose docker-compose-v2 docker-doc podman-docker containerd runc | cut -f1)

69

70

71

==== 3.2.1 Set up Docker's apt repository ====

72

73

74

# Add Docker's official GPG key:

75

sudo apt-get update

76

sudo apt-get install ca-certificates curl

77

sudo install -m 0755 -d /etc/apt/keyrings

78

sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc

79

sudo chmod a+r /etc/apt/keyrings/docker.asc

80

81

# Add the repository to Apt sources:

82

echo \

83

"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \

84

$(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \

85

sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt-get update

==== 3.2.2 Install Docker ====

90

91

To install a specific version of Docker Engine, start by listing the available versions in the repository:

92

93

94

apt list --all-versions docker-ce

95

96

docker-ce/noble 5:29.1.5-1~ubuntu.24.04~noble <arch>

107

108

==== 3.2.3 Customization ====

109

110

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.

111

112

===== 3.2.3.1 IP address range =====

113

114

Below you can find the recommended values depending on the range which can be filled in the value <ip-address> below:

115

* 10.0.0.1/8

116

** advised value 10.25.0.1/16

117

* 172.16.0.1/12

121

122

123

sudo nano /etc/docker/daemon.json

124

#Add following lines

125

{"bip": "<ip-address>"}

126

127

128

{{warning}}Be aware that the customization will only take effect once you have restarted Docker.{{/warning}}

143

144

=== 3.3 Update Docker ===

145

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:

146

147

148

apt list --all-versions docker-ce

149

150

docker-ce/noble 5:29.1.5-1~ubuntu.24.04~noble <arch>

153

154

Select the desired version and install.

155

156

157

VERSION_STRING=5:29.1.5-1~ubuntu.24.04~noble

158

sudo apt install docker-ce=$VERSION_STRING docker-ce-cli=$VERSION_STRING containerd.io docker-buildx-plugin docker-compose-plugin

159

160

161

{{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}}

162

163

===3.4 Uninstall Docker===

164

To uninstall Docker from your machine, execute the following command.

165

166

167

sudo apt purge docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin docker-ce-rootless-extras

168

169

170

{{warning}}Images, containers, volumes, or custom configuration files on your host aren't automatically removed. To delete all images, containers, and volumes:

171

172

173

sudo rm -rf /var/lib/docker

174

sudo rm -rf /var/lib/containerd

175

Remove source list and keyrings

sudo rm /etc/apt/sources.list.d/docker.sources

180

sudo rm /etc/apt/keyrings/docker.asc

181

182

183

== 4. Key takeaways ==

184

185

* 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

186

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

187

* 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.
