anchor.diff:  The only step you need to take is to set the following
   environment variables:
   
  -    export VAULT_ADDR='http://127.0.0.1:8200'
  +    export VAULT_ADDR='http://ip-172-31-26-180.ec2.internal:8200'
   
   The unseal key and root token are reproduced below in case you
   want to seal/unseal the Vault or play with authentication.

   . Run the command to configure Vault CLI to identify the server:
   +
   ```
  -export VAULT_ADDR='http://127.0.0.1:8200'
  +export VAULT_ADDR='http://ip-172-31-26-180.ec2.internal:8200'
   ```
