Upgrading Apigee hybrid to version 1.6

Upgrading to version 1.6.9 overview.

The procedures for upgrading Apigee hybrid are organized in the following sections:

  1. Backup your hybrid installation.
  2. Check your Kubernetes version and upgrade as appropriate.
  3. Install hybrid runtime version 1.6.9.
  4. Upgrade ASM.

Prerequisite

These upgrade instructions assume you have Apigee hybrid 1.5 installed and wish to upgrade it to version 1.6.9. If you are updating from an earlier version see the instructions for Upgrading Apigee hybrid to version 1.5.

Upgrade to version 1.6

  1. These instructions use the environment variable $APIGEECTL_HOME for the directory in your file system where the apigeectl utility is installed. If needed, cd into your apigeectl directory and define the variable with the following command:

    Linux

    export APIGEECTL_HOME=$PWD
    echo $APIGEECTL_HOME

    Mac OS

    export APIGEECTL_HOME=$PWD
    echo $APIGEECTL_HOME

    Windows

    set APIGEECTL_HOME=%CD%
    echo %APIGEECTL_HOME%
  2. (Recommended) Make a backup copy of your version 1.5 $APIGEECTL_HOME/ directory. For example:
    tar -czvf $APIGEECTL_HOME/../apigeectl-v1.5-backup.tar.gz $APIGEECTL_HOME
  3. (Recommended) Back up your Cassandra database following the instructions in Cassandra backup and recovery
  4. Upgrade your Kubernetes platform to the versions supported by hybrid 1.6. Follow your platform's documentation if you need help.
  5. If you are running a version of cert-manager prior to v1.5.4, you need to upgrade it to v1.5.4.
    1. Check the current cert-manager version using the following command:

      kubectl -n cert-manager get deployment -o yaml | grep 'image:'
      

      Something similar to the following is returned:

      image: quay.io/jetstack/cert-manager-controller:v1.5.4
      image: quay.io/jetstack/cert-manager-cainjector:v1.5.4
      image: quay.io/jetstack/cert-manager-webhook:v1.5.4
    2. Remove the deployments using the following command:
      $ kubectl delete -n cert-manager deployment cert-manager cert-manager-cainjector cert-manager-webhook
      
    3. Upgrade cert-manager to v1.5.4 version using the following command:
      $ kubectl apply -f https://github.com/jetstack/cert-manager/releases/download/v1.5.4/cert-manager.yaml
      
  6. Create the apigee-runtimeservice account required for use with Google OAUTH tokens. Use the create-service-account tool:
    1. Create the service account:
      ./tools/create-service-account --env prod --profile apigee-runtime
    2. Add the new service account to your Apigee overrides.yaml file:
      envs:
       - name: "environment-name"
         … … …
         serviceAccountPaths:
           runtime: "path-to-service-account-file"
         … … …
  7. Add the udca.serviceAccountPath property at the top level in your overrides file, in addition to the entry under envs. udca must appear in your overrides twice, once at the environment level and once at the organization level, parallel with connectAgent, logger, mart, metrics, and watcher.

    For example:

    … … …
    
    metrics:
      serviceAccountPath: "metrics-service-account-file"
    
    udca:
      serviceAccountPath: "udca-service-account-file"
    
    watcher:
      serviceAccountPath: "watcher-service-account-file"
    … … …
  8. Optional: If plan to use Cloud trace ensure your apigee-runtime service account has the Cloud Trace Agent (roles/cloudtrace.agent) Google role. You can do so in the Cloud console > IAM & Admin > Service accounts UI or with the following commands:
    1. Get the email address for your apigee-runtime service account with the following command:
      gcloud iam service-accounts list --filter "apigee-runtime"

      If it matches the pattern apigee-runtime@$ORG_NAME.iam.gserviceaccount.com, you can use that pattern in the next step.

    2. Assign the Cloud Trace Agent role to the service account:
      gcloud projects add-iam-policy-binding $PROJECT_ID \
          --member="serviceAccount:apigee-runtime@$PROJECT_ID.iam.gserviceaccount.com" \
          --role="roles/cloudtrace.agent"

      WWhere: $PROJECT_ID is the name of the Google Cloud project where Apigee hybrid is installed.

Install the hybrid 1.6.9 runtime

  1. Be sure you are in the hybrid base directory (the parent of the directory where the apigeectl executable file is located):
    cd $APIGEECTL_HOME/..
  2. Download the release package for your operating system using the following command. Be sure to select your platform in the following table:

    Linux

    Linux 64 bit:

    curl -LO \
      https://storage.googleapis.com/apigee-release/hybrid/apigee-hybrid-setup/1.6.9/apigeectl_linux_64.tar.gz

    Mac OS

    Mac 64 bit:

    curl -LO \
      https://storage.googleapis.com/apigee-release/hybrid/apigee-hybrid-setup/1.6.9/apigeectl_mac_64.tar.gz

    Windows

    Windows 64 bit:

    curl -LO ^
      https://storage.googleapis.com/apigee-release/hybrid/apigee-hybrid-setup/1.6.9/apigeectl_windows_64.zip
  3. Rename your current apigeectl/ directory to a backup directory name. For example:

    Linux

    mv $APIGEECTL_HOME/ $APIGEECTL_HOME-v1.5/

    Mac OS

    mv $APIGEECTL_HOME/ $APIGEECTL_HOME-v1.5/ 

    Windows

    rename %APIGEECTL_HOME% %APIGEECTL_HOME%-v1.5 
  4. Extract the downloaded gzip file contents into your hybrid base directory. The hybrid base directory is the directory where the renamed apigeectl-v1.5 directory is located:

    Linux

    tar xvzf filename.tar.gz -C ./

    Mac OS

    tar xvzf filename.tar.gz -C ./

    Windows

    tar xvzf filename.zip -C ./
  5. The tar contents are, by default, expanded into a directory with the version and platform in its name. For example: ./apigeectl_1.6.9-d591b23_linux_64. Rename that directory to apigeectl using the following command:

    Linux

    mv directory-name-linux apigeectl

    Mac OS

    mv directory-name-mac apigeectl

    Windows

    rename directory-name-windows apigeectl
  6. Change to the apigeectl directory:
    cd ./apigeectl

    The apigeectl executable is in this directory.

  7. These instructions use the environment variable $APIGEECTL_HOME for the directory in your file system where the apigeectl utility is installed. If needed, cd into your apigeectl directory and define the variable with the following command:

    Linux

    export APIGEECTL_HOME=$PWD
    echo $APIGEECTL_HOME

    Mac OS

    export APIGEECTL_HOME=$PWD
    echo $APIGEECTL_HOME

    Windows

    set APIGEECTL_HOME=%CD%
    echo %APIGEECTL_HOME%
  8. Verify the version of apigeectl with the version command:
    ./apigeectl version
    Version: 1.6.9
  9. Move to the hybrid-base-directory/hybrid-files directory. The hybrid-files directory is where configuration files such as the overrides file, certs, and service accounts are located. For example:
    cd $APIGEECTL_HOME/../hybrid-files
  10. Verify that kubectl is set to the correct context using the following command. The current context should be set to the cluster in which you are upgrading Apigee hybrid.
    kubectl config get-contexts | grep \*
  11. In the hybrid-files directory:
    1. Update the following symbolic links to $APIGEECTL_HOME. These links allow you to run the newly installed apigeectl command from inside the hybrid-files directory:
      ln -nfs $APIGEECTL_HOME/tools tools
      ln -nfs $APIGEECTL_HOME/config config
      ln -nfs $APIGEECTL_HOME/templates templates
      ln -nfs $APIGEECTL_HOME/plugins plugins
    2. To check that the symlinks were created correctly, execute the following command and make sure the link paths point to the correct locations:
      ls -l | grep ^l
    3. Do a dry run initialization to check for errors:
      ${APIGEECTL_HOME}/apigeectl init -f ./overrides/OVERRIDES.yaml --dry-run=client

      Where OVERRIDES is the name of your overrides file.

    4. If there are no errors, initialize hybrid 1.6.9:
      ${APIGEECTL_HOME}/apigeectl init -f ./overrides/OVERRIDES.yaml
    5. Check the initialization status:
      ${APIGEECTL_HOME}/apigeectl check-ready -f ./overrides/OVERRIDES.yaml
    6. Check for errors with a dry run of the apply command:
      ${APIGEECTL_HOME}/apigeectl apply -f ./overrides/OVERRIDES.yaml --dry-run=client
    7. If there are no errors, apply your overrides. Select and follow the instructions for production environments or demo/experimental environments, depending on your installation.

      Production

      For production environments you should upgrade each hybrid component individually, and check the status of the upgraded component before proceeding to the next component.

      1. Be sure you are in the hybrid-files directory.
      2. Apply your overrides to upgrade Cassandra:
        ${APIGEECTL_HOME}/apigeectl apply -f ./overrides/OVERRIDES.yaml --datastore
      3. Check completion:
        ${APIGEECTL_HOME}/apigeectl check-ready -f ./overrides/OVERRIDES.yaml

        Proceed to the next step only when the pods are ready.

      4. Apply your overrides to upgrade Telemetry components and check completion:
        ${APIGEECTL_HOME}/apigeectl apply -f ./overrides/OVERRIDES.yaml --telemetry
        ${APIGEECTL_HOME}/apigeectl check-ready -f ./overrides/OVERRIDES.yaml
      5. Bring up Redis components:
        ${APIGEECTL_HOME}/apigeectl apply -f ./overrides/OVERRIDES.yaml --redis
      6. Apply your overrides to upgrade the org-level components (MART, Watcher and Apigee Connect) and check completion:
        ${APIGEECTL_HOME}/apigeectl apply -f ./overrides/OVERRIDES.yaml --org
        ${APIGEECTL_HOME}/apigeectl check-ready -f ./overrides/OVERRIDES.yaml
      7. Apply your overrides to upgrade your environments. You have two choices:
        • Environment by environment: Apply your overrides to one environment at a time and check completion. Repeat this step for each environment:
          ${APIGEECTL_HOME}/apigeectl apply -f ./overrides/OVERRIDES.yaml --env ENV_NAME
          ${APIGEECTL_HOME}/apigeectl check-ready -f ./overrides/OVERRIDES.yaml

          Where ENV_NAME is the name of the environment you are upgrading.

        • All environments at one time: Apply your overrides to all environments at once and check completion:
          ${APIGEECTL_HOME}/apigeectl apply -f ./overrides/OVERRIDES.yaml --all-envs
          ${APIGEECTL_HOME}/apigeectl check-ready -f ./overrides/OVERRIDES.yaml

      Demo/Experimental

      In most demo or experimental environments, you can apply the overrides to all components at once. If your demo/experimental environment large and complex or closely mimics a production environment, you may want to use the instructions for upgrading production environments

      1. Be sure you are in the hybrid-files directory.
      2. ${APIGEECTL_HOME}/apigeectl apply -f ./overrides/OVERRIDES.yaml
      3. Check the status:
        ${APIGEECTL_HOME}/apigeectl check-ready -f ./overrides/OVERRIDES.yaml

Upgrade ASM to version 1.12

Perform the upgrade using the ASM documentation appropriate for your platform:

The instructions to install and configure ASM are different depending on your platform. The platforms are divided into the following categories:

  • GKE: Google Kubernetes Engine clusters running on Google Cloud.
  • Outside Google Cloud: Anthos clusters running on:
    • Anthos clusters on VMware (GKE on-prem)
    • Anthos on bare metal
    • Anthos clusters on AWS
    • Amazon EKS
  • Other Kubernetes Platforms: Conformant clusters created and running on:
    • AKS
    • EKS
    • OpenShift

GKE

The sequence for upgrading to ASM version 1.12.9 for your hybrid installation is as follows:

  1. Prepare for the upgrade.
  2. Install the new version of ASM.
  3. Delete the previous ASM version's deployments, services, and webhooks from your current installation.
  4. Upgrade your gateways and configure the new webhooks.

To upgrade to ASM version 1.12.9 for hybrid on GKE:

  1. Review the requirements in Upgrade Anthos Service Mesh, but do not perform the upgrade yet.
  2. Before installing the new version, determine the current revision. You will need this information to delete the previous ASM version's deployments, services, and webhooks from your current installation. Use the following command to store the current istiod revision to an environment variable:
    export DELETE_REV=$(kubectl get deploy -n istio-system -l app=istiod -o jsonpath={.items[].metadata.labels.'istio\.io\/rev'}'{"\n"}')
    echo ${DELETE_REV}
  3. Create a new overlay.yaml file or verify that your existing overlay.yaml contains the following contents:
    apiVersion: install.istio.io/v1alpha1
    kind: IstioOperator
    spec:
      revision: asm-1129-3
      components:
        ingressGateways:

AKS / EKS

In these instructions the process of upgrading Anthos Service Mesh (ASM) version istio-1.12.9-asm.3 on Anthos attached clusters is the same as performing a fresh install.

Preparing to install Anthos Service Mesh

  1. Delete the mutating webhook and validating webhook:
    1. cd into the directory where you installed asmcli.
    2. Store the current new revision in an environment variable to use in the script to delete the webhooks:
      UPGRADE_REV="asm-1129-3"
    3. create a shell script containing the following commands:

  2. Install Anthos Service Mesh with istioctl using the asm-multicloud profile:
    istioctl install \
        --set profile=asm-multicloud \
        --set revision="asm-1129-3" \
        --filename overlayfile.yaml

    Your output should look something like:

    kubectl get pods -n istio-system
    NAME                                   READY   STATUS    RESTARTS   AGE

    istiod-asm-1129-3-798ffb964-fnj8c       1/1     Running   1          3m21s

    The --set revision argument adds a revision label in the format istio.io/rev=asm-1129-3 to istiod. The revision label is used by the automatic sidecar injector webhook to associate injected sidecars with a particular istiod revision. To enable sidecar auto-injection for a namespace, you must label it with a revision that matches the label on istiod.

  3. Verify that your install completed:
    kubectl get svc -n istio-system

In these instructions the process of upgrading Anthos Service Mesh (ASM) version istio-1.12.9-asm.3 on Anthos attached clusters is the same as performing a fresh install.

Preparing to install Anthos Service Mesh

  1. Delete the mutating webhook and validating webhook:
    1. cd into the directory where you installed asmcli.
    2. Store the current new revision in an environment variable to use in the script to delete the webhooks:
      UPGRADE_REV="asm-1129-3"
    3. create a shell script containing the following commands:
      #!/bin/bash
      
      set -ex
      
      kubectl label namespace istio-system istio.io/rev=${UPGRADE_REV} istio-injection- --overwrite
      kubectl rollout restart deployment -n istio-system
      kubectl apply -n istio-system -f PATH_TO_INGRESSGATEWAYistio-ingressgateway
      
      if [[ "${DELETE_REV}" != "${UPGRADE_REV}" ]]; then
        kubectl apply -f out/asm/istio/istiod-service.yaml
        kubectl delete deploy -l app=istio-ingressgateway,istio.io/rev=${DELETE_REV} -n istio-system --ignore-not-found=true
        kubectl delete deploy -l app=istio-ingressgateway-connectors,istio.io/rev=${DELETE_REV} -n istio-system --ignore-not-found=true
        kubectl delete ValidatingWebhookConfiguration -l app=istiod,istio.io/rev=${DELETE_REV} -n istio-system --ignore-not-found=true
        kubectl delete MutatingWebhookConfiguration -l app=sidecar-injector,istio.io/rev=${DELETE_REV} -n istio-system --ignore-not-found=true
        kubectl delete Service,Deployment,HorizontalPodAutoscaler,PodDisruptionBudget istiod-${DELETE_REV} -n istio-system --ignore-not-found=true

Rolling back an upgrade

Follow these steps to roll back a previous upgrade:

  1. Clean up completed jobs for the hybrid runtime namespace, where NAMESPACE is the namespace specified in your overrides file, if you specified a namespace. If not, the default namespace is apigee:
    kubectl delete job -n NAMESPACE \
      $(kubectl get job -n NAMESPACE \
      -o=jsonpath='{.items[?(@.status.succeeded==1)].metadata.name}')
  2. Clean up completed jobs for the apigee-system namespace:
    kubectl delete job -n apigee-system \
      $(kubectl get job -n apigee-system \
      -o=jsonpath='{.items[?(@.status.succeeded==1)].metadata.name}')
  3. Change the APIGEECTL_HOME variable to point to the directory that contains the previous version of apigeectl. For example:
    export APIGEECTL_HOME=PATH_TO_PREVIOUS_APIGEECTL_DIRECTORY
  4. In the root directory of the installation you want to roll back to, run ${APIGEECTL_HOME}/apigeectl apply, check the status of your pods, and then run ${APIGEECTL_HOME}/apigeectl init. Be sure to use the original overrides file for the version you wish to roll back to:
    1. In the hybrid-files directory, run ${APIGEECTL_HOME}/apigeectl apply:
      ${APIGEECTL_HOME}/apigeectl apply -f ./overrides/ORIGINAL_OVERRIDES.yaml
    2. Check the status of your pods:
      kubectl -n NAMESPACE get pods

      Where NAMESPACE is your Apigee hybrid namespace.

    3. Check the status of apigeeds:
      kubectl describe apigeeds -n apigee

      Your output should look something like:

      Status:
        Cassandra Data Replication:
        Cassandra Pod Ips:
          10.8.2.204
        Cassandra Ready Replicas:  1
        Components:
          Cassandra:

              Version:   v1
            Replicas:
              Available:  1
              Ready:      1
              Total:      1
              Updated:    1
            State:        running
        Scaling:

          Operation:
          Requested Replicas:  0
        State:                 running

      Proceed to the next step only when the apigeeds ßpod is running.

    4. Run apigeectl init:
      ${APIGEECTL_HOME}/apigeectl init -f ./overrides/ORIGINAL_OVERRIDES.yaml
