🔨How to Configure HashiCorp Vault

1. Configure .env/.env.docker files in auth-service folder

VAULT_PROVIDER = "hashicorp"

Note: VAULT_PROVIDER can be set to "database" or "hashicorp" to select Database instance or a hashicorp vault instance correspondingly.

If the VAULT_PROVIDER value is set to "hashicorp" the following 3 parameters should be configured in auth-service folder.

1. HASHICORP_ADDRESS : http://localhost:8200 for using local vault. For remote vault, we need to use the value from the configuration settings of Hashicorp vault service.

2. HASHICORP_TOKEN : the token from the Hashicorp vault.

3. HASHICORP_WORKSPACE : this is only needed when we are using cloud vault for Hashicorp. Default value is "admin".

2. Hashicorp should be configured with the created Key-Value storage, named "secret" by default, with the settingKey=<value> records for the following keys:

1. OPERATOR_ID

2. OPERATOR_KEY

3. IPFS_STORAGE_API_KEY

Note: These records in vault will be created automatically if there are environment variables with the matching names.
