Deployment types

Since agola is composed of multiple components you can deploy it in many different ways based on your requirements and scaling needs. Here some examples:

Prerequisites

• An etcd cluster
• An object storage:
  • A posix shared fs like nfs or cephfs
  • A S3 based storage

Create a configuration file with the correct entries to your etcd, objectstorage and components config (see the configuration reference)

High available with N executors

Start all the management components (except executor)

agola serve --config ./config-localhost.yml --components all-base

You can have N instances of all the base components for high availability and scaling (with the current exclusion of the git server used for user direct runs that is currently a single instance so only one of the n started will be used based on the gateway gitserverURL setting in your config file)

Start the executors

On every “executor” machine:

agola serve --config ./config-localhost.yml --components executor
