Configuring Trust Framework attribute caching for development

While building and testing policies in a development environment, you can define an external attribute cache for the Trust Framework.

About this task

When you set the Policy Decision Service to external policy decision point (PDP) mode, the Policy Editor is configured by default to cache attribute values in memory on the PingAuthorize Server (for any attributes with a defined caching strategy). Alternatively, you can define an external attribute cache using Redis by configuring the options.yml file. The available Redis modes include:

Single Redis instance
Single Redis instance using TLS
Replicated Redis
Redis Sentinel
Amazon Web Services (AWS) ElastiCache Redis

Steps

Make a copy of the default options file:

Example:
```
$ cp config/options.yml my-options.yml
```
In the cache section of the new options file, uncomment the line provider: redis to enable the Redis caching options.
Uncomment the desired Redis cacheConfig block and modify it to reflect your Redis instance settings.

Example:
```
cache:
  provider:redis
  cacheConfig:
    mode: single_instance
    nodeAddresses: redis://localhost:6379
#   username: <optional>
#   password: <optional>
```
1. Optional: Uncomment username and password and add the appropriate values.
Stop the Policy Editor:

Example:
```
$ bin/stop-server
```

Run setup using the --optionsFile argument and customize all other options as appropriate for your needs:

Example:

$ bin/setup demo \
  --adminUsername admin \
  --generateSelfSignedCertificate \
  --decisionPointSharedSecret pingauthorize \
  --hostname  <pap-hostname>  \
  --port  <pap-port>  \
  --adminPort  <admin-port>  \
  --licenseKeyFile  <path-to-license>  \
  --optionsFile my-options.yml

Start the Policy Editor:

Example:
```
$ bin/start-server
```
