It uses the [`app-role`](https://www.vaultproject.io/docs/auth/approle.html), [`app-id` authentication mechanism](https://www.vaultproject.io/docs/auth/app-id.html) or simple [token authentication](https://www.vaultproject.io/docs/auth/token.html) to identify itself with the Vault server, fetches all fields in the specified key and returns export directives for bash / zsh. That way you can do `eval` stuff and pull those fields into your ENV. ## Usage In general this program can either output your ENV variables to use with `eval` or similar or it can run a program with populated environment. ``` # vault2env [secret path] [command] # vault2env --export [secret path] export ... ``` ### Using evironment variables ```bash # export VAULT_ADDR="https://127.0.0.1:8200" # export VAULT_APP_ID="29c8febe-49f5-4620-a177-20dff0fda2da" # export VAULT_USER_ID="54d24f66-6ecb-4dcc-bdb7-0241a955f1df" # vault2env secret/my/path/with/keys export FIRST_KEY="firstvalue" export SECOND_KEY="secondvalue" # eval $(vault2env secret/my/path/with/keys) # echo "${FIRST_KEY}" firstvalue ``` ### Using CLI parameters The command does differ only with its parameters specified for the different authentication mechanisms: - When using AppRole you need to specify `--vault-role-id` and optionally `--vault-secret-id` if you're using the `bind_secret_id` flag for your AppRole - When using AppID specify `--vault-app-id` and `--vault-user-id` - When using Token auth only specify `--vault-token` ```bash # vault2env --vault-addr="..." --vault-app-id="..." --vault-user-id="..." secret/my/path/with/keys export FIRST_KEY="firstvalue" export SECOND_KEY="secondvalue" ``` Though it's possible to use CLI parameters I strongly recommend to stick to the ENV variant as it's possible under certain conditions to read CLI parameters on a shared system using for example `ps aux`.
