Upgrade Kf on Google Cloud

As part of the upgrade procedure, ensure that your Kf installation uses the latest version of the Kf operator:

• Confirm your current Kf version can upgrade to Kf v2.10.0.
• Upgrade to Kf v2.10.0.
• Upgrade dependencies (if needed).

Before you begin

You will need:

• An existing cluster with Kf installed.
• Access to a machine with gcloud , kf , and kubectl installed.

Prepare for the upgrade

Connect to your target cluster

 gcloud  
container  
clusters  
get-credentials  
 CLUSTER_NAME 
  
 \ 
  
--zone  
 CLUSTER_ZONE 
  
 \ 
  
--project  
 CLUSTER_PROJECT_ID 
 

Confirm that your current Kf CLI and server versions match

Run kf debug and validate the Kf CLI and Kf server versions match.

• The CLI version is listed under Kf Client .
• The Kf server version is listed under kf["app.kubernetes.io/version"] .

 $ kf debug
...
Version: Kf Client:                        v2.7.3Server version:                   v1.21.6-gke.1500 kf["app.kubernetes.io/version"]:  v2.7.3... 

If the Kf client and Kf server values do notmatch, but the server version is v2.7.x, install the Kf v2.10.0 CLI before you continue.

If the Kf server value is older than v2.7.x, you must first incrementally upgrade to Kf v2.7.x to continue.

Confirm that Kf is healthy before upgrading

Run kf doctor to check the state of your cluster. Ensure all tests pass before you continue.

 $ kf doctor
...
=== RUN doctor/user
=== RUN doctor/user/ContainerRegistry
--- PASS: doctor/user
   --- PASS: doctor/user/ContainerRegistry
... 

If you see any FAIL or Error: environment failed checks messages, follow the guidance in the kf doctor output, or view the troubleshooting guide to resolve the issue and retry the command until it is successful.

Upgrade the operator

The Kf operator performs upgrades for you.

1. Apply the operator yaml:

   kubectl apply -f "https://storage.googleapis.com/kf-releases/v2.10.0/operator.yaml"

Upgrade Kf dependencies

1. Upgrade Tekton:

   kubectl apply -f "https://storage.googleapis.com/tekton-releases/pipeline/previous/v0.32.1/release.yaml"

2. Upgrade to Cloud Service Mesh v1.12:

   1. Follow the steps in the Cloud Service Mesh upgrade guide .

1. Upgrade/Install Config Connector:

   For upgrading from Kf v2.8: Please follow the steps in the 'Install Config Connector' step in Kf Install

   For upgrading from Kf v2.7:

   1. Download the required Config Connector Operator tar file.

   2. Extract the tar file.

       tar  
      zxvf  
      release-bundle.tar.gz 
      

   3. Install the Config Connector operator on your cluster.

       kubectl  
      apply  
      -f  
      operator-system/configconnector-operator.yaml 
      

Upgrade to the Kf v2.10.0 CLI

1. Install the CLI:

   Linux

   This command installs the Kf CLI for all users on the system. Follow the instructions in the Cloud Shell tab to install it just for yourself.

    gcloud  
   storage  
   cp  
   gs://kf-releases/v2.10.0/kf-linux  
   /tmp/kf 
    chmod  
   a+x  
   /tmp/kf 
    sudo  
   mv  
   /tmp/kf  
   /usr/local/bin/kf 
   

   Mac

   This command installs kf for all users on the system.

    gcloud  
   storage  
   cp  
   gs://kf-releases/v2.10.0/kf-darwin  
   /tmp/kf 
    chmod  
   a+x  
   /tmp/kf 
    sudo  
   mv  
   /tmp/kf  
   /usr/local/bin/kf 
   

   Cloud Shell

   This command installs kf on your Cloud Shell instance if you use bash , the instructions may need to be modified for other shells.

    mkdir  
   -p  
   ~/bin 
    gcloud  
   storage  
   cp  
   gs://kf-releases/v2.10.0/kf-linux  
   ~/bin/kf 
    chmod  
   a+x  
   ~/bin/kf 
     echo 
     
    "export PATH= 
    $HOME 
    /bin: 
    $PATH 
    " 
    >> 
   ~/.bashrc 
     source 
     
   ~/.bashrc 
   

   Windows

   This downloads kf to current directory. Add it to the path if you want to call if from anywhere other than the current directory.

    gcloud  
   storage  
   cp  
   gs://kf-releases/v2.10.0/kf-windows.exe  
   kf.exe 
   

2. Validate the Kf CLI and Kf server versions match:

   • The CLI version is listed under Kf Client .
   • The Kf server version is listed under kf["app.kubernetes.io/version"] .

    $ kf debug
   ...
   Version: Kf Client:                        v2.10.0Server version:                   v1.21.6-gke.1500 kf["app.kubernetes.io/version"]:  v2.10.0... 
   

Verify that Kf upgraded successfully

1. Run doctor to ensure the newly installed version is healthy:

    kf  
   doctor  
   --retries = 
    20 
    
   

   The command runs cluster checks several times. It's normal for a few of the attempts to fail while the new controllers are starting.

   If the command fails with the message Error: environment failed checks , follow the guidance in the doctor output to resolve the issue and retry the command until it is successful.

If the verification steps pass, your cluster has successfully been upgraded! If you have any issues, please review the support page for guidance.
