Failed to install Converged Edge Insights

[EricHsu]

Hi Teams,

I tried to install the Converged Edge Insights on a single node configuration, but I failed in this.

After digging into the log files, it seemed caused by adding an old HELM chart repository.

I post parts of log file as below. Could someone help me resolve it? Thank you!

Hi Eric,

Looks like the Helm stable URL location has changed and it causes the openness installation to fail. You can fix it by modifying the following two files.

In file roles/telemetry/grafana/tasks/main.yml,

  - name: add default Helm repository
-    command: helm repo add stable https://kubernetes-charts.storage.googleapis.com/
+    command: helm repo add stable https://charts.helm.sh/stable
    changed_when: true
    when: not offline_enable

And in file roles/telemetry/prometheus/tasks/main.yml,

  - name: add default Helm repository
-    command: helm repo add stable https://kubernetes-charts.storage.googleapis.com/
+	command: helm repo add stable https://charts.helm.sh/stable
    changed_when: true
    when: not offline_enable

Tried this option but it didn't help. The installation scripts are overwriting these files and failing at the same point Is there any way to prevent that? .

Hi @ChunSheong_F_Intel,

I got the same phenomenon with @RaviKira. Is there any way to resolve it?

Such as modify the source version of the OpenNESS.

Hi  @ChunSheong_F_Intel,

 Is there any solution? we are stuck at the installation. 

 I tried changing the "edgesoftware_configuration.xml" to take 20.12 version of OpenNESS as github is showing these files corrected. But looks like the edgesoftware binary is downloading it from somewhere else. 

Thanks

Hi Ravi, 

We're working with the engineering team to provide the solution for this as we're aware that the current installation script will just re-write any changes made in these two files. We will update once we have the solution for this. 

[EricHsu]

Hi @RaviKira ,

I had tried this method before. However, it didn't work.

The version control of it seems embedded in the installation tool. FYI.

I could't find a way to change the version so far.

Regards,

Eric

[ChunSheong_F_Intel]

Hi Eric,

Meanwhile, you can use the following manual steps to install Openness.

1. Modify the two files as I mentioned above
2. cd Converged_Edge_Insights_20.06/OpenNESS/openness-experience-kits/
3. cat inventory.ini -> check ip for controller and node
4. ./deploy_ne.sh

Let me know if it doesn't work.

[EricHsu]

Hi @ChunSheong_F_Intel ,

This is a standard installation process of the OpenNESS.

I think it should be work, but just a workaround, right?

Eventually, I hope the installation can be completed by the standard installation method of the Converged Edge Insight package. Thank you!

Regards,

Eric

[ChunSheong_F_Intel]

Hi @EricHsu 

That's right, we will update our installation script internally to fix this issue so that you do not need to do this workaround in the future.

[RaviKira]

Hi,

 Sorry, there are more obsolete links even with this workaround. 

Error occurred. Will retry after 5 seconds. You can find details below:
Failure downloading http://linuxsoft.cern.ch/scientific/7x/x86_64/os/Packages/tuned-2.11.0-8.el7.noarch.rpm, HTTP Error 404: Not Found

============

I solved it with a workaround by updating the links in the following files. 

group_vars/edgenode_group/10-default.yml:
host_vars/_example_variables.yml:-
roles/machine_setup/configure_tuned/defaults/main.yml:

replaced the following lines 

# - http://linuxsoft.cern.ch/scientific/7x/x86_64/os/Packages/tuned-2.11.0-8.el7.noarch.rpm

# -  http://linuxsoft.cern.ch/scientific/7x/x86_64/os/Packages/tuned-profiles-realtime-2.11.0-8.el7.noarch.rpm

with
- http://ftp.pbone.net/mirror/vault.centos.org/7.7.1908/cr/x86_64/Packages/tuned-2.11.0-8.el7.noarch.rpm

- ftp://ftp.pbone.net/mirror/ftp.scientificlinux.org/linux/scientific/7.8/x86_64/os/Packages/tuned-profiles-realtime-2.11.0-8.el7.noarch.rpm

==========

But still stuck with the below error when I do ./build_ne.sh single

ERROR: unsatisfiable constraints:

The SUDO command version issue is I guess is related to:

Not sure how to resolve this !! Please guide.

Hi Ravi, 

We have new release for the Converged Edge Insights that will help to fix this issue. 

You can go to this link here to download: https://software.intel.com/iot/edgesoftwarehub/download/home/convergededgeinsights/ 

Thanks

[RaviKira]

Thank you. Now the installation is resolved.

(Worked despite of the fact that the memory requirements of the servers doubled in this new release).
