vault: post policy as HCL; find a more ergonomical approach for creating policies via the http api

[noahehall]

C

• we need the ability to write policies in HCL, with any level of complexity, and post those HCL policies to a vault server

T

• [ ] dude you just need to convert the policy to a string with quotes escaped, see below

A

• @see https://github.com/hashicorp/vault/issues/18551
  • found a workaround but im sure theres a way to send valid hcl / json without having to parse it

creating policy policy_admin_vault:
path "secret/*" { # kv-v2
  capabilities = [ "create", "read", "update", "delete", "list", "patch", "sudo"]
}

path "env/*" { # kv-v1
  capabilities = [ "create", "read", "update", "delete", "list", "patch", "sudo"]
}

path "sys/*" {
  capabilities = [ "create", "read", "update", "delete", "list", "patch", "sudo" ]
}

path "auth/*" {
  capabilities = [ "create", "read", "update", "delete", "list", "patch", "sudo" ]
}

path "database/*" {
  capabilities = [ "create", "read", "update", "delete", "list", "patch", "sudo" ]
}

path "pki*" {
  capabilities = [ "create", "read", "update", "delete", "list", "patch", "sudo" ]
}

resolution

• your gonna have to write an hcl parser that escapes the double quotes everywhere, in order to send a string that parses back into valid hcl
  • vault wont accept the payload if you simplify convert the hcl to json
