Integrates SPIFFE SVID authentication with Hashicorp Vault to retrieve a VAULT_TOKEN.
-
Read secrets from Hashicorp Vault Hashicorp Vault without providing a secret to authenticate against Hashicorp Vault. Instead we will be using a SPIFFE SVID to authenticate ourself against Hashicorp Vault.
-
Perform secretless/keyless code signing by utilizing the Hashicorp Vault Transit engine as a software defined HSM. This resolves the issue of having signing keys on a local machine as well resolves the issue of managing secrets to access the signing keys. Again we utilize the SPIFFE SVID to authenticate against Hashicorp Vault.
make build$ export VAULT_ADDR=http://localhost:8200
$ bin/spiffe-vault auth -role my-role
# Export following environment variable to authenticate to Hashicorp Vault
export VAULT_TOKEN=s.IK1LBrCGXFQDAgawmhNLbcDHDepending on the shell you are using you can automatically export the variable.
bash
$ export VAULT_ADDR=http://localhost:8200
$ echo "$(bin/spiffe-vault auth -role my-role)" > /tmp/spiffe-vault
$ source /tmp/spiffe-vault
$ vault kv get secrets/my-key
