Add Custom Certificate During Deployment

Warning

We are currently working on making the setup and upgrade process to Automate HA a seamless experience. If you are already using Chef Automate HA, or are planning to use it, please contact your customer success manager or account manager for more information.

Custom certificates can be added during deployment for different services.

Setting common certificates for all the nodes of a service

The following services support custom certificates:

Common custom certificate for Chef Automate

To add a common custom certificate for all the nodes of the Chef Automate service, add the configurations given below in the config.toml file before running the chef-automate deploy command:

[automate.config]
enable_custom_certs = true

# Add Automate Load Balancer root-ca
root_ca = """ADD_YOUR_ROOT_CA_HERE"""

# Add Automate node internal public and private keys
private_key = """ADD_YOUR_PRIVATE_KEY_HERE"""
public_key = """ADD_YOUR_PUBLIC_KEY_HERE"""

Common custom certificate for Chef Server

To add a common custom certificate for all the nodes of the Chef Server service, add the configurations given below in the config.toml file before running the chef-automate deploy command:

[chef_server.config]
enable_custom_certs = true
private_key = """ADD_YOUR_PRIVATE_KEY_HERE"""
public_key = """ADD_YOUR_PUBLIC_KEY_HERE"""

Common custom certificate for OpenSearch

To add a common custom certificate for all the nodes of the OpenSearch service, add the configurations given below in the config.toml file before running the chef-automate deploy command:

[opensearch.config]
enable_custom_certs = true
root_ca = """ADD_YOUR_ROOT_CA_CERT_HERE"""
private_key = """ADD_YOUR_PRIVATE_KEY_HERE"""
public_key = """ADD_YOUR_PUBLIC_KEY_HERE"""
admin_key = """ADD_YOUR_ADMIN_KEY_HERE"""
admin_cert = """ADD_YOUR_ADMIN_CERT_HERE"""

Common custom certificate for PostgreSQL

To add a common custom certificate for all the nodes of the PostgreSQL service, add the configurations given below in the config.toml file before running the chef-automate deploy command:

[postgresql.config]
enable_custom_certs = true
root_ca = """ADD_YOUR_ROOT_CA_CERT_HERE"""
private_key = """ADD_YOUR_PRIVATE_KEY_HERE"""
public_key = """ADD_YOUR_PUBLIC_KEY_HERE"""

Setting unique certificates for different nodes of a service

For on-prem installations, the following services support unique custom certificates for different nodes:

Note

If you are using unique custom certificates for each node of a service, then you can skip the Public and Private Keys before the certs_by_ip section for that service.
If you are using unique custom certificates for each node of a service, then make sure to define keys for all the IPs for that service. For example, if you are using 3 nodes for PostgreSQL service, then you need to define keys for all 3 IPs using 3 certs_by_ip sections.
If you have defined keys at both the places (common and inside the certs_by_ip section), then the keys defined in the certs_by_ip section will be used.

Unique custom certificates for Chef Automate

To add unique custom certificates for 2 the nodes of the Chef Automate service, add the configurations given below in the config.toml file before running the chef-automate deploy command:

[automate.config]
enable_custom_certs = true

# Add Automate Load Balancer root-ca
root_ca = """ADD_YOUR_ROOT_CA_CERT_HERE"""

[[automate.config.certs_by_ip]]
ip = "ADD_YOUR_FIRST_IP_ADDRESS_HERE"
private_key = """ADD_YOUR_PRIVATE_KEY_OF_FIRST_IP_ADDRESS_HERE"""
public_key = """ADD_YOUR_PUBLIC_KEY_OF_FIRST_IP_ADDRESS_HERE"""
[[automate.config.certs_by_ip]]
ip = "ADD_YOUR_SECOND_IP_ADDRESS_HERE"
private_key = """ADD_YOUR_PRIVATE_KEY_OF_SECOND_IP_ADDRESS_HERE"""
public_key = """ADD_YOUR_PUBLIC_KEY_OF_SECOND_IP_ADDRESS_HERE"""

Unique custom certificates for Chef Server

To add unique custom certificates for 2 the nodes of the Chef Server service, add the configurations given below in the config.toml file before running the chef-automate deploy command:

[chef_server.config]
enable_custom_certs = true
[[chef_server.config.certs_by_ip]]
ip = "ADD_YOUR_FIRST_IP_ADDRESS_HERE"
private_key = """ADD_YOUR_PRIVATE_KEY_OF_FIRST_IP_ADDRESS_HERE"""
public_key = """ADD_YOUR_PUBLIC_KEY_OF_FIRST_IP_ADDRESS_HERE"""
[[chef_server.config.certs_by_ip]]
ip = "ADD_YOUR_SECOND_IP_ADDRESS_HERE"
private_key = """ADD_YOUR_PRIVATE_KEY_OF_SECOND_IP_ADDRESS_HERE"""
public_key = """ADD_YOUR_PUBLIC_KEY_OF_SECOND_IP_ADDRESS_HERE"""

Unique custom certificates for OpenSearch

To add unique custom certificates for 3 of the nodes of the OpenSearch service, add the configurations given below in the config.toml file before running the chef-automate deploy command:

[opensearch.config]
enable_custom_certs = true
root_ca = """ADD_YOUR_ROOT_CA_CERT_HERE"""
admin_key = """ADD_YOUR_ADMIN_KEY_HERE"""
admin_cert = """ADD_YOUR_ADMIN_CERT_HERE"""
[[opensearch.config.certs_by_ip]]
ip = "ADD_YOUR_FIRST_IP_ADDRESS_HERE"
private_key = """ADD_YOUR_PRIVATE_KEY_OF_FIRST_IP_ADDRESS_HERE"""
public_key = """ADD_YOUR_PUBLIC_KEY_OF_FIRST_IP_ADDRESS_HERE"""
[[opensearch.config.certs_by_ip]]
ip = "ADD_YOUR_SECOND_IP_ADDRESS_HERE"
private_key = """ADD_YOUR_PRIVATE_KEY_OF_SECOND_IP_ADDRESS_HERE"""
public_key = """ADD_YOUR_PUBLIC_KEY_OF_SECOND_IP_ADDRESS_HERE"""
[[opensearch.config.certs_by_ip]]
ip = "ADD_YOUR_THIRD_IP_ADDRESS_HERE"
private_key = """ADD_YOUR_PRIVATE_KEY_OF_THIRD_IP_ADDRESS_HERE"""
public_key = """ADD_YOUR_PUBLIC_KEY_OF_THIRD_IP_ADDRESS_HERE"""

Unique custom certificates for PostgreSQL

To add unique custom certificates for 3 of the nodes of the PostgreSQL service, add the configurations given below in the config.toml file before running the chef-automate deploy command:

[postgresql.config]
enable_custom_certs = true
root_ca = """ADD_YOUR_ROOT_CA_CERT_HERE"""
[[postgresql.config.certs_by_ip]]
