Running the software locally

1. Setup the variables. There are three approaches to setup the necessary variables for this application.
   • Getting variables from vault.

     export VAULT_ADDR="https://{{vault_url}}"
     export GITHUB_TOKEN="{{github_token}}"
     

   • Read variables from the config file. The config file must follow this json structure.

     {
         "sesamConfig": {
             "host": "{{host for the API}}",
             "desc": "{{host description}}",
             "jwt": "{{token}}"
         }
     }
     

   • Setup the variables in your local env.

     export SESAM_HOST=...
     export HOST_DESC=...
     export HOST_JWT=...
     

2. Running the code from the source code

   go run . -config.vault
