Upgrade of Portal

Below are the notes specific for the TLab environment. If a change is made in OOM charts then the following needs to be completed to upgrade the running charts in

    1. Find Rancher IP in R_Control-Plane tenant - we use “onap_dev” key and “Ubuntu” user to SSH. For example: “ssh -i onap_dev ubuntu@192.168.31xx.245xxx”.
    2. Login as ubuntu, then run "sudo -i" to login as root. The “oom” git repo is in the rancher vm's root directory, under “/root/oom”.
    3. Edit portal files at /root/oom/kubernetes

      “make portal”

      “make onap”
      Run below command from "/root” folder to do helm upgrade

      "helm upgrade -i dev local/onap -f ../../integration-override.yaml"/portal....

    4. When complete run the following from /root/oom/kubernetes  dir

      Code Block
      languagebash
      themeMidnight
      > make portal
....
> make onap
....
# This will do the upgrade:
helm upgrade dev local/onap --namespace onap -f onap/resources/environments/disable-allcharts.yaml --set portal.enabled=true
# When complete run the following to ensure its in the process of coming up or complete. 
kubectl get pods -n onap -o wide | grep portal

      In case, if it is a fresh install, try below command:

      Code Block
      languagebash
      themeMidnight
      helm install ./onap/ -n onap --namespace onap -f onap/resources/environments/disable-allcharts.yaml --set portal.enabled=true

      Stop command to stop any old namespace:

      Code Block
      languagebash
      themeMidnight
      helm del onap --purge
    5. Rancher gui is at 192.168.31xx.245xxx:8080
      There is an interactive cli as well in the rancher gui where you can run kubectl commands.

    6. Below command will show the list of portal services

portal-app Resiliency

A portal-app container failure can be simulated by stopping the portal-app container.    The kubernetes liveness operation will detect that the ports are down, inferring there's a problem with the service, and in turn, will restart the container. 

...

To find all portal pods:

Code Block
languagebash
themeMidnight
> kubectl get pods --all-namespaces | grep portal
onap          dev-portal-app-b8c6668d8-56bjb                2/2       Running       0          2m

onap          dev-portal-sdk-868f696cd7-mnjxk               0/2       Init:0/1      0          2m

From above list, now to check DB logs:
