03 - Deploy Supporting Charms¶

This part of the tutorial focuses on deploying supporting charms that Airbyte requires for metadata storage, workflow orchestration, and object storage.

Requirement	Charm	Purpose
Database	postgresql-k8s	Stores metadata, job configurations, and sync history
Workflow Engine	temporal-k8s	Manages task queues and workflow execution
Admin UI	temporal-admin-k8s	Manages Temporal namespaces and admin tasks
Object Storage	minio or S3 Integrator	Stores sync logs, state, and artifacts

Note: Either MinIO or S3 Integrator can be used; not both.

Deploy PostgreSQL¶

juju deploy postgresql-k8s --channel 14/stable --trust
juju status --watch 2s

Note: Deployment may take ~10 minutes. Expect active status for all units once complete.

Deploy MinIO¶

juju deploy minio --channel ckf-1.10/stable
juju status --watch 2s

Note: Deployment completes when all units are active.

Deploy Temporal¶

juju deploy temporal-k8s --config num-history-shards=4  # This value can be set to 1024 or 2048 for a production deployment
juju deploy temporal-admin-k8s
juju status --watch 2s

Note: Temporal requires num-history-shards to be a power of 2.

Ignore temporary blocked messages; they will be resolved once relations are added in the next step.
