ClickHouse Cloud Credentials

ClickHouse Cloud Credentials

Establish dual credential storage pattern (Doppler + 1Password) for ClickHouse Cloud authentication.

Purpose

Store and backup ClickHouse Cloud credentials in two secure locations:

1. Doppler (aws-credentials/​prd project) - Runtime environment variables
2. 1Password (Engineering vault) - Secure backup and team access

This skill guides the workflow of storing 8 required credentials for gapless-crypto-clickhouse service.

When to Use

Use this skill when:

• New service setup: Initial credential storage for new ClickHouse Cloud service
• Credential rotation: Updating API keys or database passwords
• Backup verification: Ensuring credentials exist in both storage locations
• Team onboarding: Documenting required credentials for new team members

Triggers: User mentions "store credentials", "Doppler", "1Password", "ClickHouse API keys", "credential rotation"

Prerequisites

Credentials to Store:

• API Key ID and Secret (from ClickHouse Cloud console)
• Organization ID (from ClickHouse Cloud API)
• Service ID (gapless-crypto-clickhouse service)
• Connection parameters (host, port, user, password)

Required Access:

• Doppler CLI access to aws-credentials/​prd project
• 1Password CLI (op) access to Engineering vault

Credential Schema

Doppler Secrets (aws-credentials/​prd)

8 required secrets:

See: references/​doppler-schema.md for detailed descriptions

1Password Item (Engineering Vault)

Vault: Engineering (fnzrqcsl3pl3bcdojrxf46whnu) Item Title: "ClickHouse Cloud - gapless-crypto-cli"

8 required fields:

See: references/​onepassword-schema.md for detailed specifications

Workflow

Step 1: Store API Credentials in Doppler

# Store API Key ID and Secret
doppler secrets set CLICKHOUSE_CLOUD_KEY_ID "<key_id>" --project aws-credentials --config prd
doppler secrets set CLICKHOUSE_CLOUD_KEY_SECRET "<key_secret>" --project aws-credentials --config prd

Step 2: Store Organization and Service Metadata in Doppler

# Store IDs
doppler secrets set CLICKHOUSE_CLOUD_ORG_ID "<org_id>" --project aws-credentials --config prd
doppler secrets set CLICKHOUSE_CLOUD_SERVICE_ID "a3163f31-21f4-4e22-844e-ef3fbc26ace2" --project aws-credentials --config prd

Step 3: Store Connection Details in Doppler

# Store connection parameters
doppler secrets set CLICKHOUSE_HOST "ebmf8f35lu.us-west-2.aws.clickhouse.cloud" --project aws-credentials --config prd
doppler secrets set CLICKHOUSE_PORT "8443" --project aws-credentials --config prd
doppler secrets set CLICKHOUSE_USER "default" --project aws-credentials --config prd
doppler secrets set CLICKHOUSE_PASSWORD "<db_password>" --project aws-credentials --config prd

Step 4: Backup Credentials in 1Password

# Create 1Password item with all fields
op item create --vault Engineering \
  --category "API Credential" \
  --title "ClickHouse Cloud - gapless-crypto-cli" \
  username="<key_id>" \
  credential="<key_secret>" \
  "organization_id[text]=<org_id>" \
  "organization_name[text]=TE's Organization" \
  "service_id[text]=a3163f31-21f4-4e22-844e-ef3fbc26ace2" \
  "service_name[text]=gapless-crypto-cli" \
  "database_password[password]=<db_password>" \
  "console_url[url]=https://clickhouse.cloud/"

Step 5: Verify Storage

# Verify Doppler secrets (names only)
doppler secrets --project aws-credentials --config prd --only-names | grep CLICKHOUSE

# Verify 1Password item
op item get "ClickHouse Cloud - gapless-crypto-cli" --vault Engineering

Success Criteria

• ✅ All 8 secrets stored in Doppler (aws-credentials/​prd)
• ✅ All 8 fields stored in 1Password (Engineering vault)
• ✅ No plaintext credentials in version control
• ✅ Credentials accessible via Doppler CLI
• ✅ Backup accessible via 1Password CLI

Security Notes

1. No secrets in code: Reference Doppler key names, never hardcode values
2. Dual storage: Doppler for runtime, 1Password for backup and team access
3. Credential rotation: Update both Doppler and 1Password when rotating
4. Access control: Doppler and 1Password enforce team-based access controls
5. Audit trail: Both systems log credential access for security monitoring

Troubleshooting

Issue: "Doppler secrets not found"

• Check: Verify project name aws-credentials and config prd
• Verify: doppler projects list shows project exists

Issue: "1Password vault not accessible"

• Check: Engineering vault ID: fnzrqcsl3pl3bcdojrxf46whnu
• Verify: op vault list shows Engineering vault

Issue: "Credential format incorrect"

• Check: API Key ID format (example: xnIdJM3n42LDImsZ9zzg)
• Verify: UUIDs are valid format (8-4-4-4-12 hex digits)
