In some situations, the Smartfacts server has no access to the internet. In this case, it is not possible to download the needed software and images. This article describes which options we have to install Smartfacts in such scenarios.

...

Preparations

Server

Please provide a server that meets the following requirements:

• CPU:

  • x64 / AMD64 processor - ARM based servers will not work

  • Minimum: 6 Cores

• RAM: minimum 32 GB

• Hard disk: minimum 150 GB

  Most of the data will be stored under /var/lib/rancher/k3s

• Operating System: Linux

  All Linux distributions running K3s can be used.

  If you are using a Red Hat / CentOS Linux, please perform these preparations:

  • It is recommended to turn off firewalld:

    systemctl disable firewalld --now

  • If enabled, it is required to disable nm-cloud-setup and reboot the node:

    systemctl disable nm-cloud-setup.service nm-cloud-setup.timer

    reboot

• The user performing the installation will need sudo privileges

• The server must be connected to the internet

DNS

Please define a domain for Smartfacts. Either add a wildcard entry *.<domain-name> to the DNS or enter the required URLs individually:

• smartfacts.<domain-name>

• camp.<domain-name>

• identity.<domain-name>

• genoslc.<domain-name>

• oslc.<domain-name>

Certificates

Please prepare certificates for the server which meet the following requirements:

• It is an X.509 certificate which is suitable for server authentication

• Base64-coded in PEM format

• Hostnames

  • The certificat must be issued on the hostnames

    • smartfacts.<domain-name>

    • camp.<domain-name>

    • identity.<domain-name>

    • genoslc.<domain-name>

    • oslc.<domain-name>

  • Hostnames must also be stored in the "Subject Alternative Name" attribute of the certificate

  • All hostnames and subject alternative names must be written in lower case

• The certificat must be valid (valid from, valid to)

• It is suitable for the provided private key

• The private key may not be password protected

• The certificate should comprise the complete certificate chain where possible

  If this is missing, then an attempt is made to download the missing intermediate and root certificate during installation.

Install the software

If not done so far please prepare your infrastructure as described in https://smartfacts.atlassian.net/wiki/spaces/SPD/pages/54624257/Installing+Smartfacts+for+Proof+of+Concepts#Prepare-your-infrastructure.

Setup the Kubernetes Environment

Download the software

• Download “k3s” and “k3s-airgap-images-amd64.tar.gz” from the “Assets” section “Assets” at of https://github.com/k3s-io/k3s/releases - use version v1.27.9+k3s1
  

  Image Added

• Download the Helm binaries for Linux amd64 from https://github.com/helm/helm/releases

• Copy the content contents of the K3s install script at https://get.k3s.io into a new text file named called “install.sh”

• Download the file https://cp.mid.de/releases/smartfacts-air-gapped/install_airgapped_software.sh

Copy the files to the server

• In your home directory, create Create a new directory “download” in your home directory

• Create a new directory “software” under “download”

• Copy all downloaded files to ~/download/software
  After copying all files, the file structure should look like this:
  

  Code Block
  download └── software ├── helm-v3.10.3-linux-amd64.tar.gz ├── install.sh ├── install_airgapped_software.sh ├── k3s └── k3s-airgap-images-amd64.tar.gz

...

Download the Smartfacts Helm Chart

• Log with the provided credential into the Smartfacts Chart Registry using the credentials provided and download the latest chart version that does not have contain the postfix “-dev”.

• Copy the downloaded helm chart to your home directory on the Smartfacts server

• Extract the helm chart with using the command

  Code Block
  tar -xvzfxf smartfacts-*.tgz

Create the deployment configuration

Provide Certificates and Key as Base64 String

The Prerequisite is: The complete certificate chain is available in a file as base64-encoded x509 certificates. The certificates are contained in the file in the correct order (server certificate at the top, root certificate at the bottom). See Section “Certificates” above in this article.

Save the certificate chain as a base64-encoded string:

cat <your certificate chain.crt> | base64 -w0 > chain.crt.base64

Save certificate key as a base64-encoded string:

cat <your certificate key.key> | base64 -w0 > key.base64

Customize Values File

• Change to the home directory of your user 's home directory on the server and create a new text file values.yaml with the following content:

  Code Block

  global: domain: "<your-domain>" instance: "smartfacts-poc" registry: "library" cert: crtFullChain: "<FULL-CHAIN-CERT-BASE64>" key: "<CERT-KEY-BASE64>" ingress: enabled: true # Smartfacts supports Traefik and nginx as Ingress Controller. # The default is Traefik. # If you use nginx as ingress controller please comment in this line: #ingressClassType: "nginx" spa: cspConf: externalUrls: "" # space separated list of your tool urls (IBM Jazz, Jama, Codebeamer) plugin: importPlugins: true # "true" for first installation, "false" for minor updates will speed up the update process a lot genoslc: enabled: false mailservice: enabled: false camp: enabled: false genoslckafka: enabled: false

• Replace the value of the property domain property with your domain name.

• Replace the placeholder of the property crtFullChain property with the content of the file chain.crt.base64.

• Replace the placeholder of the property key property with the content of the key.base64 file.

• Save the file values.yaml file.

Provide the container images

The Kubernetes environment at the Smartfacts server needs to must have access to the Smartfacts container images of Smartfacts.

The recommended way of providing to gain access to the container images is to add the Smartfacts registry https://repo.mid.de to an existing container registry at in your company which organisation that has access to the internet. This registry works serves as a proxy registry , so that the air gapped Smartfacts server can load the Smartfacts images through that this proxy registry. Follow the instructions in the section Provide container images with a proxy container registry if you can use a proxy registry.

If it is not possible to use a proxy repositoryregistry, the container images can be loaded directly into the container service at of the Smartfacts server. To do this, follow the instructions in the section Provide container images without a container registry.

{
  "auths":
  {
    "<proxy registry name>" :
    {
      "username":"<username>",
      "password":"<password>"
    }
  }
}

title Provide container images without a container registry
Provide container images without a container registry In this scenario you will download the container images manually and copy it to the server. Enter Call up the web page for downloading the container images. The link of to the web page contains the chart version. It has the following format: https://cp.mid.de/releases/smartfacts-air-gapped/smartfacts_air_gapped_<HELM_CHART_VERSION>.html Make shure sure to replace the placeholder <HELM_CHART_VERSION> with the version of the helm chart you have downloaded. You should now see the download page. Download all files to your client PC create Create a new directory ~/download/smartfacts on the Smartfacts server copy Copy the downloaded files to ~/download/smartfacts on the Smartfacts server Download the script for loading to load the images from https://cp.mid.de/releases/smartfacts-air-gapped/loadimages.sh and copy it to ~/download/smartfacts on the Smartfacts server Load the container images into k3s On the Smartfacts server Change into the directory ~/download/smartfacts make Make the script “loadimages.sh” executeable and execute it Code Block chmod u+x loadimages.sh ./loadimages.sh The script will check if checks wether all files are present and correct. If this is the case, it will load the container images from the files. To save disk space, you can delete the image- and sha256-files the directory after loading. You can view the loaded images with the following command. Code Block sudo k3s crictl images

Install Smartfacts

Execute the Installation

...

sudo helm upgrade --install --timeout 15m0s smartfacts ./smartfacts -f values.yaml --version 4.7.5-genoslcv2 -n smartfacts --create-namespace

...

sudo watch kubectl get deployments -n smartfacts

After all deployments are availabe, you can enter the camp page to set up users.

Enter the following command to show the URLs (please make sure to prefix it with “https://” in your browser):

sudo kubectl get ingress -n smartfacts

Prepare the Smartfacs Model Warehouse

A note on Smartfacts PoC Test Users

For the Smartfacts PoC you can use the generated test users “poc1”…”poc50”. All poc-users have the same password “poc”. For managing the test users in the CAMP use the account administrator user “acm” which has the password “acm”.

Setting-Up the CAMP (Customer Accounts for MID Products)

This section is used to add the users who will be authorized to use the instance and to assign the licenses. When you open https://camp.<yoursmartfactsdomain>, and log in with the user “acm” (password “acm”) you will be taken to this page:

...

1. In section 1, upload the license file MID has provided in step 4 by clicking the  upload button in the upper right-hand corner and by selecting the license file.

2. In section 2, set an account name.

3. In section 3, synchronize the users from OpenLDAP to CAMP by clicking UPDATE USERS AND GROUPS.

4. Assign licenses to users and groups in the CAMP.

   Check all users and/or groups that should have a license and assign licenses by clicking ASSIGN LICENSES.

The creation of the account is now complete and licenses are assigned to the users.

Create a Smartfacts Model Warehouse

1. Open the Smartfacts URL in your browser: https://smartfacts.<yoursmartfactsdomain> and log-in with the account manager credentials (user “acm”, password “acm”).

2. You will now be asked to create a Model Warehouse.

   1. Click on CREATE A NEW MODEL WAREHOUSE.

   2. In the create dialog, first select the previously created account.

   3. Provide a name for the Model Warehouse.

   4. Optionally, activate the check box Create Demo Models if you want some demo content to be added to the Model Warehouse.

Model Warehouse creation is the final step in the Smartfacts platform set-up process.

Install the Plug-Ins

It depends on which tools you want to use in connection with Smartfacts. Smartfacts provides a plug-in for every tool which is supported. You can download the plug-ins from the main menu via the command Get Plug-ins.
