How to pass environmental variables in envconsul config file?

kubernetes minikube consul hashicorp-vault

I. Within container specification set environmental variables (values in double quotes):

env:  - name: VAULT_TOKEN    value: "abcd1234"  - name: VAULT_ADDR    value: "http://10.0.2.2:8200"

Then refer to the values in envconsul.hcl

vault {  address = ${VAULT_ADDR}  renew_token = false  retry {    backoff = "1s"  }  token = ${VAULT_TOKEN}}

II. Another option is to unseal the vault cluster (with the unseal key which was printed while initializing the vault cluster)

$ vault operator unseal

and then authenticate to the vault cluster using a root token.

$ vault login <your-generated-root-token>

kubernetes minikube consul hashicorp-vault

I tried many suggestions and nothing worked until I passed -vault-token argument to envconsul command like this:

envconsul -vault-token=$VAULT_TOKEN -config=/app/config.hcl -secret="/secret/debug/service" env

and in config.hcl it should be like this:

 vault {  address     = "http://kvstorage.try.direct:8200"  token       = "${env(VAULT_TOKEN)}" }
