Ansible playbooks to deploy Apigee Hybrid using Helm Charts

This repository contains a set of Ansible roles and playbooks to manage the installation, configuration and maintenance of Apigee Hybrid in your environment. Apigee Hybrid components are managed using helm charts through ansible roles.Apigee Hybrid combines the power of Apigee's API management with the flexibility and control of Kubernetes. With this playbooks, you can automate common Apigee Hybrid management tasks, making it easier to deploy, configure, and maintain your Apigee Hybrid clusters.

Refer the official doc for more details on Helm charts for Apigee Hybrid.

Authenticate gcloud and helm

Authenticate to gcloud cli as shown below

Ensure the Authenticating user OR service account has roles/apigee.admin role.

gcloud auth application-default login

[Optional] Authenticate to helm registry if using self hosted or private registry

gcloud auth application-default print-access-token | helm registry login -u oauth2accesstoken \
--password-stdin https://<artifact-registry-region>-docker.pkg.dev

Usage

Below are some of the usage patterns.

Primary DC Installation Only

To deploy Apigee Hybrid in 1 Region only run the ansible playbook as shown below

ansible-playbook playbook.yaml -e @vars/vars.yaml  --tags "dc1"

Primary & Secondary DC Installation Only

To deploy Apigee Hybrid in 2 Regions run the ansible playbook as shown below

ansible-playbook playbook.yaml -e @vars/vars.yaml

Decommission Primary DC Only

To decommission Apigee Hybrid in the first region run the ansible playbook as shown below

ansible-playbook decommission.yaml -e @vars/vars.yaml --tags dc1

Decommission Primary & Secondary DC

To decommission Apigee Hybrid from both Regions run the ansible playbook as shown below

ansible-playbook decommission.yaml -e @vars/vars.yaml

Apigee Hybrid Component management

To manage components via playbook you need to run playbook while passing the selective ansible tag.Some scenarios are listed below

Validate the provided inputs

To validate the inputs given to ansible

ansible-playbook playbook.yaml -e @vars/vars.yaml  --tags "validate-input"

Validate the current setup

To validate a running setup by executing mock APIs.

ansible-playbook playbook.yaml -e @vars/vars.yaml  --tags "validate"

To Update Apigee VirtualHost

To update the Apigee Virtual Hosts.

ansible-playbook playbook.yaml -e @vars/vars.yaml  --tags "validate-input,generte-overrides,apigee-virtualhost,wait_virtualhost,validate"

Cassandra Custom Storage Classes

To use custom storage classes for cassandra statefulsets, you can populate the storageClass parameter in the vars file that you are using. By defining a custom storage class, it will first be created in your cluster and then set as the storage class of the cassandra statefulsets. You will also need to specify the provisionerType and the parameters. You can use the following provisioners:

gke
aks
eks
anthos-vsphere-csi Note: If you face any issues with any of the provisioners, please create a github issue in this repository

Running Known Issue fixes.

Note: In case of multi-dc , this needs to be run against each DC. Ensure the relevant kubernetes context is configured.

To run the fixes for known issues.

ansible-playbook known_issues.yaml

Note: Currently fix for following issues are supported.
