Vaultify templates file from vault secrets and auto renews leases

vaultify has three commands, template, renew-leases, and run

The template command reads a template, renders the vault secrets into it, and stores the result in a file. In addition it also stores the secret lease information in a secrets file to be able to renew the leases.

template.yaml example:

credentials:
    <{- $admin := vault "database/creds/maindb-admin" }>
    username: <{ $admin.Data.username | quote }>
    password: <{ $admin.Data.password | quote }>

Running vaultify template:

vaultify template --vault https://vault.vault:8200 \
                  --role maindb-admin \
                  --template-file template.yaml \
                  --output-file /app/config.yaml \
                  --secrets-output-file /app/secrets.json \
                  -vv

The renew-leases command renews leases that for created by template command and stored in a secrets file.

Running vaultify renew-leases:

vaultify renew-leases --vault https://vault.vault:8200 \
                      --secrets-output-file /app/secrets.json \
                      --metrics-address ":9105" \
                      -vv

Running vaultify and continuously renew leases:

vaultify run --vault https://vault.vault:8200 \
             --role maindb-admin \
             --template-file template.yaml \
             --output-file /app/config.yaml \
             --metrics-address ":9105" \
             -vv

Note that running only this might not work for all work loads. If you run your application in kubernetes and your configuration needs to be rendered before the application starts, you should run the template command in a initContainer and the renew-leases command in a side-car.

Vaultify run and renew-leases are exposing the following metrics:
