Kubernetes Basics

Quick start guide for deploying Elsa Workflows to Kubernetes with PostgreSQL persistence, including configuration, troubleshooting, and production best practices.

This guide provides a practical introduction to deploying Elsa Workflows on Kubernetes with PostgreSQL persistence. It focuses on common deployment patterns and configuration challenges, helping you move from SQLite (development) to PostgreSQL (production).

Note: For comprehensive Kubernetes deployment documentation including Helm charts, autoscaling, monitoring, and service mesh integration, see the Full Kubernetes Deployment Guide.

Overview

This guide covers:

Using Kubernetes manifests from the elsa-core repository
Switching from SQLite to PostgreSQL for production
Common configuration pitfalls and how to avoid them
Troubleshooting database connectivity and persistence

Prerequisites

Kubernetes cluster (v1.24+) - Minikube, k3s, or cloud provider (EKS, AKS, GKE)
kubectl CLI configured to access your cluster
Basic understanding of Kubernetes concepts (Pods, Services, ConfigMaps, Secrets)
PostgreSQL database (managed or self-hosted)

Understanding the elsa-core Kubernetes Manifests

The elsa-core repository includes sample Kubernetes manifests in the scripts/ directory (if available). These manifests provide a starting point for deploying Elsa Server and Studio to Kubernetes.

Typical Manifest Structure

elsa-core/
├── scripts/
│   ├── kubernetes/
│   │   ├── elsa-server-deployment.yaml
│   │   ├── elsa-server-service.yaml
│   │   ├── elsa-studio-deployment.yaml
│   │   ├── configmap.yaml
│   │   └── secrets.yaml (template)

Note: The exact structure may vary by version. Always refer to the latest elsa-core repository for current manifest examples. If manifests are not present, use the examples in this guide as a starting point.

What the Manifests Provide

elsa-server-deployment.yaml: Deployment for Elsa Server (workflow runtime and API)
elsa-studio-deployment.yaml: Deployment for Elsa Studio (designer UI)
services.yaml: ClusterIP or LoadBalancer services for external access
configmap.yaml: Application configuration (connection strings, feature flags)
secrets.yaml: Sensitive data (database passwords, API keys)

Default Configuration: SQLite

By default, Elsa Server deployments often use SQLite for simplicity:

Default ConfigMap:

apiVersion: v1
kind: ConfigMap
metadata:
  name: elsa-config
data:
  ConnectionStrings__DefaultConnection: "Data Source=/app/data/elsa.db"
  Elsa__Persistence__Provider: "Sqlite"

Why SQLite is Used:

Zero configuration required
Works out of the box
Suitable for demos and development

Why SQLite is NOT Suitable for Production:

Single-file database: Does not support multiple pods (no horizontal scaling)
No concurrent writes: Workflow execution errors under load
Data loss risk: Data is lost if the pod restarts (unless using PersistentVolume)
Limited performance: Not optimized for high-throughput scenarios

Never use SQLite in production Kubernetes deployments. Always use PostgreSQL, SQL Server, or MySQL for production workloads.

Switching to PostgreSQL

To use PostgreSQL in Kubernetes, you need to:

Deploy or connect to a PostgreSQL database
Update connection strings and environment variables
Configure Elsa modules to use the PostgreSQL provider
Apply database migrations

Step 1: Deploy PostgreSQL (Optional)

If you don't have an external PostgreSQL instance, deploy one in Kubernetes:

postgres-deployment.yaml:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: postgres-pvc
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: postgres
spec:
  replicas: 1
  selector:
    matchLabels:
      app: postgres
  template:
    metadata:
      labels:
        app: postgres
    spec:
      containers:
      - name: postgres
        image: postgres:16
        env:
        - name: POSTGRES_DB
          value: elsa_workflows
        - name: POSTGRES_USER
          value: elsa_user
        - name: POSTGRES_PASSWORD
          valueFrom:
            secretKeyRef:
              name: postgres-secret
              key: password
        ports:
        - containerPort: 5432
        volumeMounts:
        - name: postgres-storage
          mountPath: /var/lib/postgresql/data
      volumes:
      - name: postgres-storage
        persistentVolumeClaim:
          claimName: postgres-pvc
---
apiVersion: v1
kind: Service
metadata:
  name: postgres
spec:
  selector:
    app: postgres
  ports:
  - port: 5432
    targetPort: 5432
  type: ClusterIP

postgres-secret.yaml:

apiVersion: v1
kind: Secret
metadata:
  name: postgres-secret
type: Opaque
stringData:
  password: "your-secure-password-here"  # Change this!

Apply the manifests:

kubectl apply -f postgres-secret.yaml
kubectl apply -f postgres-deployment.yaml

Production Recommendation: Use managed PostgreSQL services (Amazon RDS, Azure Database for PostgreSQL, Google Cloud SQL) instead of self-hosting in Kubernetes for better reliability, automated backups, and reduced operational overhead.

Step 2: Update Elsa Server Configuration

Changing the connection string alone is not enough. You must also configure the persistence provider in the Elsa modules.

Option A: Environment Variables

Update the Elsa Server deployment to use PostgreSQL:

elsa-server-deployment.yaml:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: elsa-server
spec:
  replicas: 1  # Start with 1 for testing. Production: 3+ for HA and rolling updates
  selector:
    matchLabels:
      app: elsa-server
  template:
    metadata:
      labels:
        app: elsa-server
    spec:
      containers:
      - name: elsa-server
        image: elsaworkflows/elsa-server:latest
        env:
        # Connection string
        - name: ConnectionStrings__PostgreSql
          value: "Host=postgres;Database=elsa_workflows;Username=elsa_user;Password=$(POSTGRES_PASSWORD)"
        - name: POSTGRES_PASSWORD
          valueFrom:
            secretKeyRef:
              name: postgres-secret
              key: password
        
        # Persistence configuration
        - name: Elsa__Persistence__Provider
          value: "PostgreSql"
        - name: Elsa__Persistence__ConnectionStringName
          value: "PostgreSql"
        
        # Module configuration
        - name: Elsa__Modules__Management__Persistence__Provider
          value: "EntityFrameworkCore.PostgreSql"
        - name: Elsa__Modules__Runtime__Persistence__Provider
          value: "EntityFrameworkCore.PostgreSql"
        
        ports:
        - containerPort: 8080
        - containerPort: 8081

Option B: ConfigMap and appsettings.json

Mount a ConfigMap as appsettings.Production.json:

elsa-configmap.yaml:

apiVersion: v1
kind: ConfigMap
metadata:
  name: elsa-config
data:
  appsettings.Production.json: |
    {
      "ConnectionStrings": {
        "PostgreSql": "Host=postgres;Database=elsa_workflows;Username=elsa_user;Password=$(POSTGRES_PASSWORD)"
      },
      "Elsa": {
        "Modules": {
          "Management": {
            "Persistence": {
              "Provider": "EntityFrameworkCore.PostgreSql",
              "ConnectionStringName": "PostgreSql"
            }
          },
          "Runtime": {
            "Persistence": {
              "Provider": "EntityFrameworkCore.PostgreSql",
              "ConnectionStringName": "PostgreSql"
            }
          }
        }
      }
    }

Deployment with ConfigMap:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: elsa-server
spec:
  template:
    spec:
      containers:
      - name: elsa-server
        image: elsaworkflows/elsa-server:latest
        env:
        - name: ASPNETCORE_ENVIRONMENT
          value: "Production"
        - name: POSTGRES_PASSWORD
          valueFrom:
            secretKeyRef:
              name: postgres-secret
              key: password
        volumeMounts:
        - name: config
          mountPath: /app/appsettings.Production.json
          subPath: appsettings.Production.json
      volumes:
      - name: config
        configMap:
          name: elsa-config

Step 3: Configure Persistence in Program.cs

If you're building a custom Elsa Server image, configure PostgreSQL persistence in Program.cs:

using Elsa.EntityFrameworkCore.Extensions;
using Elsa.EntityFrameworkCore.Modules.Management;
using Elsa.EntityFrameworkCore.Modules.Runtime;
using Elsa.Extensions;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddElsa(elsa =>
{
    // Configure Management module with PostgreSQL
    elsa.UseWorkflowManagement(management =>
    {
        management.UseEntityFrameworkCore(ef =>
        {
            ef.UsePostgreSql(
                builder.Configuration.GetConnectionString("PostgreSql"),
                options =>
                {
                    options.MigrationsHistoryTable("__EFMigrationsHistory_Management");
                }
            );
        });
    });
    
    // Configure Runtime module with PostgreSQL
    elsa.UseWorkflowRuntime(runtime =>
    {
        runtime.UseEntityFrameworkCore(ef =>
        {
            ef.UsePostgreSql(
                builder.Configuration.GetConnectionString("PostgreSql"),
                options =>
                {
                    options.MigrationsHistoryTable("__EFMigrationsHistory_Runtime");
                }
            );
        });
    });
    
    elsa.UseWorkflowsApi();
    elsa.UseHttp();
});

var app = builder.Build();

// Auto-migrate on startup (optional, can also use init containers)
if (builder.Configuration.GetValue<bool>("Elsa:AutoMigrate", false))
{
    await app.Services.MigrateElsaDatabaseAsync();
}

app.UseWorkflowsApi();
app.Run();

Why Changing Only the Connection String Isn't Enough

A common mistake is to update the connection string but forget to configure the persistence provider. This leads to:

Symptoms:

Elsa still creates elsa.db file (SQLite)
Connection string is ignored
Data not persisted to PostgreSQL

Root Cause:

Elsa modules have default persistence providers built into the code. Simply changing the connection string doesn't change the provider. You must explicitly configure each module:

// ❌ Wrong: Only changing connection string
services.AddElsa(elsa =>
{
    elsa.UseWorkflowManagement();  // Uses default provider (SQLite)
    elsa.UseWorkflowRuntime();     // Uses default provider (SQLite)
});

// ✅ Correct: Configure provider for each module
services.AddElsa(elsa =>
{
    elsa.UseWorkflowManagement(management =>
    {
        management.UseEntityFrameworkCore(ef => 
            ef.UsePostgreSql(connectionString));
    });
    
    elsa.UseWorkflowRuntime(runtime =>
    {
        runtime.UseEntityFrameworkCore(ef => 
            ef.UsePostgreSql(connectionString));
    });
});

Configuration Points:

Connection String: Specifies where to connect
Provider: Specifies how to connect (SQLite, PostgreSQL, SQL Server, etc.)
Module Configuration: Each module (Management, Runtime) needs its own provider configuration

All three must be aligned for PostgreSQL to work.

Running Database Migrations

Before Elsa Server can use PostgreSQL, the database schema must be created.

Option 1: Init Container

Use a Kubernetes init container to run migrations before the main app starts:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: elsa-server
spec:
  template:
    spec:
      initContainers:
      - name: migrations
        image: elsaworkflows/elsa-server:latest
        command: ["/bin/sh"]
        args:
        - -c
        - |
          dotnet ef database update --context ManagementElsaDbContext
          dotnet ef database update --context RuntimeElsaDbContext
        env:
        - name: ConnectionStrings__PostgreSql
          value: "Host=postgres;Database=elsa_workflows;Username=elsa_user;Password=$(POSTGRES_PASSWORD)"
        - name: POSTGRES_PASSWORD
          valueFrom:
            secretKeyRef:
              name: postgres-secret
              key: password
      containers:
      - name: elsa-server
        # ... main container config ...

Important: The above init container example assumes the Elsa Server image includes the EF Core tooling (dotnet-ef). Most production images do not include this tool for security and size reasons.

To run migrations reliably, use a dedicated migration image that includes dotnet-ef, or build a custom image for this purpose.
Alternatively, ensure your main image has the necessary tooling, but this is not recommended for production.

Option 2: Auto-Migration on Startup

Enable auto-migration in the application (simpler but not ideal for production):

// In Program.cs
if (builder.Configuration.GetValue<bool>("Elsa:AutoMigrate", false))
{
    await app.Services.MigrateElsaDatabaseAsync();
}

Set the environment variable in the deployment:

env:
- name: Elsa__AutoMigrate
  value: "true"

Production Best Practice: Run migrations as a separate Job or init container, not on every pod startup. This prevents race conditions when multiple pods start simultaneously.

Option 3: Kubernetes Job

Create a one-time migration Job:

elsa-migration-job.yaml:

apiVersion: batch/v1
kind: Job
metadata:
  name: elsa-migrations
spec:
  template:
    spec:
      containers:
      - name: migrations
        image: elsaworkflows/elsa-server:latest
        command: ["/bin/sh", "-c"]
        args:
        - |
          dotnet ef database update --context ManagementElsaDbContext
          dotnet ef database update --context RuntimeElsaDbContext
        env:
        - name: ConnectionStrings__PostgreSql
          value: "Host=postgres;Database=elsa_workflows;Username=elsa_user;Password=$(POSTGRES_PASSWORD)"
        - name: POSTGRES_PASSWORD
          valueFrom:
            secretKeyRef:
              name: postgres-secret
              key: password
      restartPolicy: OnFailure

Important: Similar to the init container example, this Job assumes the Elsa Server image includes the EF Core tooling (dotnet-ef). Most production images do not include this tool for security and size reasons.

To run migrations reliably, use a dedicated migration image that includes dotnet-ef, or build a custom image for this purpose.
Alternatively, ensure your main image has the necessary tooling, but this is not recommended for production.

Run the job before deploying Elsa Server:

kubectl apply -f elsa-migration-job.yaml
kubectl wait --for=condition=complete job/elsa-migrations --timeout=300s
kubectl apply -f elsa-server-deployment.yaml

Troubleshooting

Problem: Elsa Still Uses SQLite

Symptoms:

elsa.db file created in pod
PostgreSQL connection string appears in logs but isn't used
No tables created in PostgreSQL

Diagnosis:

# Check pod logs
kubectl logs -l app=elsa-server --tail=100

# Look for:
# - "Using Sqlite provider" (wrong)
# - "Using PostgreSql provider" (correct)

Fix:

Verify provider configuration in environment variables:

env:
- name: Elsa__Modules__Management__Persistence__Provider
  value: "EntityFrameworkCore.PostgreSql"

Or ensure appsettings.Production.json is mounted correctly:

kubectl exec -it deployment/elsa-server -- cat /app/appsettings.Production.json

Check that the PostgreSQL package is included in your Docker image:

# In Dockerfile
RUN dotnet add package Elsa.EntityFrameworkCore.PostgreSql

Problem: Connection Refused or Timeout

Symptoms:

Npgsql.NpgsqlException: Connection refused
or
A connection attempt failed because the connected party did not properly respond

Diagnosis:

# Check if PostgreSQL pod is running
kubectl get pods -l app=postgres

# Check PostgreSQL service
kubectl get svc postgres

# Test connection from Elsa Server pod
kubectl exec -it deployment/elsa-server -- /bin/sh
apk add postgresql-client
psql -h postgres -U elsa_user -d elsa_workflows

Fix:

Verify PostgreSQL service name matches connection string:

# Connection string must use service name
Host=postgres  # ← Must match service metadata.name

Ensure PostgreSQL is ready before Elsa Server starts:

# Add readiness probe to postgres deployment
readinessProbe:
  exec:
    command: ["pg_isready", "-U", "elsa_user"]
  initialDelaySeconds: 5
  periodSeconds: 5

Check namespace - services in different namespaces require FQDN:

# If postgres is in namespace "database"
Host=postgres.database.svc.cluster.local

Problem: Tables Not Created

Symptoms:

PostgreSQL connection succeeds
No error messages in logs
Queries fail: "relation 'Elsa_WorkflowDefinitions' does not exist"

Diagnosis:

# Connect to PostgreSQL
kubectl exec -it deployment/postgres -- psql -U elsa_user -d elsa_workflows

# List tables
\dt

# Expected tables:
# Elsa_WorkflowDefinitions
# Elsa_WorkflowInstances
# Elsa_ActivityExecutionRecords
# ... and others

Fix:

Ensure migrations ran successfully:

# Check migration job logs
kubectl logs job/elsa-migrations

# Look for:
# "Applying migration '20240101000000_InitialCreate'"
# "Done."

Manually run migrations if needed:

kubectl run -it --rm migrations --image=elsaworkflows/elsa-server:latest \
  --restart=Never \
  --env="ConnectionStrings__PostgreSql=Host=postgres;Database=elsa_workflows;Username=elsa_user;Password=..." \
  -- dotnet ef database update

Check migration history:

SELECT * FROM "__EFMigrationsHistory_Management";
SELECT * FROM "__EFMigrationsHistory_Runtime";

Problem: Missing Environment Variables

Symptoms:

Connection string contains literal $(POSTGRES_PASSWORD) instead of actual password
Authentication failures

Diagnosis:

# Check environment variables in pod
kubectl exec -it deployment/elsa-server -- printenv | grep -i postgres

# Should show:
# POSTGRES_PASSWORD=actual_password_here
# ConnectionStrings__PostgreSql=Host=postgres;...Password=actual_password_here

Fix:

Environment variable substitution in connection strings doesn't happen automatically. Use one of these approaches:

Option 1: Reference secret directly in each field:

env:
- name: DB_HOST
  value: "postgres"
- name: DB_NAME
  value: "elsa_workflows"
- name: DB_USER
  value: "elsa_user"
- name: DB_PASSWORD
  valueFrom:
    secretKeyRef:
      name: postgres-secret
      key: password
- name: ConnectionStrings__PostgreSql
  value: "Host=$(DB_HOST);Database=$(DB_NAME);Username=$(DB_USER);Password=$(DB_PASSWORD)"

Option 2: Build connection string in code:

// In Program.cs
var host = builder.Configuration["DB_HOST"];
var database = builder.Configuration["DB_NAME"];
var user = builder.Configuration["DB_USER"];
var password = builder.Configuration["DB_PASSWORD"];

var connectionString = $"Host={host};Database={database};Username={user};Password={password}";

builder.Services.AddElsa(elsa =>
{
    elsa.UseWorkflowManagement(management =>
    {
        management.UseEntityFrameworkCore(ef => ef.UsePostgreSql(connectionString));
    });
    // ...
});

Problem: ConfigMap Not Mounted

Symptoms:

Settings in ConfigMap not applied
App uses default configuration

Diagnosis:

# Check if ConfigMap exists
kubectl get configmap elsa-config -o yaml

# Verify file is mounted in pod
kubectl exec -it deployment/elsa-server -- ls -la /app/appsettings.Production.json

# Check file content
kubectl exec -it deployment/elsa-server -- cat /app/appsettings.Production.json

Fix:

Ensure volume mount path is correct:

volumeMounts:
- name: config
  mountPath: /app/appsettings.Production.json  # Must match app's config path
  subPath: appsettings.Production.json

Set ASPNETCORE_ENVIRONMENT to load the file:

env:
- name: ASPNETCORE_ENVIRONMENT
  value: "Production"

Verify ConfigMap is in the same namespace as the deployment.

Verifying PostgreSQL is Being Used

After deploying, confirm that Elsa is using PostgreSQL:

1. Check Logs

kubectl logs -l app=elsa-server --tail=50 | grep -i postgres

# Look for messages like:
# "Using PostgreSQL provider"
# "Executed DbCommand (123ms) [Parameters=[], CommandType='Text']"

2. Check Database Tables

kubectl exec -it deployment/postgres -- psql -U elsa_user -d elsa_workflows -c "\dt"

# Expected output:
#                   List of relations
#  Schema |            Name              | Type  |   Owner
# --------+------------------------------+-------+-----------
#  public | Elsa_ActivityExecutionRecords| table | elsa_user
#  public | Elsa_Bookmarks               | table | elsa_user
#  public | Elsa_WorkflowDefinitions     | table | elsa_user
#  public | Elsa_WorkflowInstances       | table | elsa_user

3. Create a Test Workflow

# Port-forward Elsa Server
kubectl port-forward svc/elsa-server 8080:80

# Create a workflow via API
curl -X POST http://localhost:8080/elsa/api/workflow-definitions/execute \
  -H "Content-Type: application/json" \
  -d '{
    "workflow": {
      "activities": [
        {
          "id": "1",
          "type": "WriteLine",
          "text": "Hello from Kubernetes!"
        }
      ]
    }
  }'

# Verify workflow instance was persisted
kubectl exec -it deployment/postgres -- psql -U elsa_user -d elsa_workflows \
  -c "SELECT id, status FROM \"Elsa_WorkflowInstances\" ORDER BY created_at DESC LIMIT 1;"

Production Best Practices

1. Use Managed PostgreSQL

Amazon RDS for PostgreSQL: Automated backups, point-in-time recovery, Multi-AZ
Azure Database for PostgreSQL: High availability, automatic patching, geo-replication
Google Cloud SQL: Automated backups, read replicas, automatic failover

2. Separate Database User Permissions

-- Create read-only user for monitoring
CREATE USER elsa_readonly WITH PASSWORD 'secure_password';
GRANT CONNECT ON DATABASE elsa_workflows TO elsa_readonly;
GRANT SELECT ON ALL TABLES IN SCHEMA public TO elsa_readonly;

-- Create migration user with schema modification rights
CREATE USER elsa_migrations WITH PASSWORD 'secure_password';
GRANT ALL PRIVILEGES ON DATABASE elsa_workflows TO elsa_migrations;

-- Application user with limited permissions
CREATE USER elsa_app WITH PASSWORD 'secure_password';
GRANT CONNECT ON DATABASE elsa_workflows TO elsa_app;
GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO elsa_app;

3. Use Connection Pooling

env:
- name: ConnectionStrings__PostgreSql
  value: "Host=postgres;Database=elsa_workflows;Username=elsa_user;Password=$(PASSWORD);Pooling=true;MinPoolSize=1;MaxPoolSize=20"

4. Enable TLS for Database Connections

env:
- name: ConnectionStrings__PostgreSql
  value: "Host=postgres;Database=elsa_workflows;Username=elsa_user;Password=$(PASSWORD);SSL Mode=Require;Trust Server Certificate=false"

5. Implement Health Checks

livenessProbe:
  httpGet:
    path: /health/live
    port: 8080
  initialDelaySeconds: 30
  periodSeconds: 10

readinessProbe:
  httpGet:
    path: /health/ready
    port: 8080
  initialDelaySeconds: 10
  periodSeconds: 5

6. Set Resource Limits

resources:
  requests:
    memory: "512Mi"
    cpu: "250m"
  limits:
    memory: "2Gi"
    cpu: "1000m"

7. Production Scaling Considerations

For production deployments, run at least 3 replicas:

spec:
  replicas: 3  # Minimum for production

Why 3+ replicas?

High Availability: If one pod fails, others continue serving traffic
Rolling Updates: Allows zero-downtime deployments (update one pod at a time)
Load Distribution: Better distribution of workflow execution across pods
Pod Disruption Budget: Can configure PDB to maintain minimum available pods

Scaling Strategy:

Development/Staging: 1-2 replicas
Production (low traffic): 3 replicas
Production (high traffic): 5-10+ replicas with HPA
Enterprise: 10+ replicas with node affinity and pod anti-affinity rules

For automatic scaling based on CPU/memory usage, see the Full Kubernetes Deployment Guide.
