Data Layer Installation

Elasticsearch​

  1. Create namespace:

    kubectl create namespace elastic

  2. Create credentials secret:

    kubectl -n elastic create secret generic elasticsearch-master-credentials \
      --from-literal=username=elastic \
      --from-literal=password="$(openssl rand -base64 12)" \
      --type=Opaque \
      --dry-run=client -o yaml | kubectl apply -f -

  3. Install Elasticsearch:

    helm upgrade --install elastic elasticsearch/. \
      -n elastic \
      --values elasticsearch/values-aws.yaml \
      --wait --timeout 900s \
      --dependency-update

Postgres-operator​

helm upgrade --install postgres-operator postgres-operator-helm/. \
  -n postgres-operator \
  --create-namespace \
  --wait --timeout 900s \
  --dependency-update

PostgreSQL secret for RDS​

Create codemie-postgresql secret:

kubectl create secret generic codemie-postgresql \
        --from-literal=PG_PASS=<CODEMIE_POSTGRES_DATABASE_PASSWORD> \
        --from-literal=PG_USER=<CODEMIE_POSTGRES_DATABASE_USER> \
        --from-literal=PG_HOST=<CODEMIE_POSTGRES_DATABASE_HOST> \
        --from-literal=PG_NAME=<CODEMIE_POSTGRES_DATABASE_NAME> \
        --namespace codemie
note

Replace <CODEMIE_POSTGRES_DATABASE_*> placeholders with actual values from your deployment_outputs.env file (see Infrastructure Deployment).

Secret example:

apiVersion: v1
kind: Secret
metadata:
  name: codemie-postgresql
  namespace: codemie
data:
  PG_HOST: <base64-encoded-host>
  PG_NAME: <base64-encoded-db-name>
  PG_PASS: <base64-encoded-password>
  PG_USER: <base64-encoded-user>
type: Opaque
